What is the solution of the following system?
Use the substitution method.
{y+7=3x6x−2y=12
The only solution is (14, 12) .
The only solution is (12, 14) .
There is no solution.
There are an infinite number of solutions.
Answer:
there is no solution
Step-by-step explanation:
y + 7 = 3x
6x - 2y = 6 which can be simplied to be 3x - y = 6 (divide by 2)
let y = 3x - 7
substitute: 3x -(3x - 7) = 6
3x - 3x + 7 = 6
7 ≠ 6 therefore, no solution

Read the excerpt from Heart of a Samurai and then answer the question.
The strangers leaped out of their boats and pulled them up on the small beach. By signs, they made it clear the castaways should climb aboard.
The fishermen exchanged frightened glances and whispered to one another,
“What about Denzo and Jusuke?”
Gesturing, Manjiro communicated to the strangers about the two men in the cave. Denzo and Jusuke were retrieved, both of them so weak they had to be carried to the boats. Everyone found a place and the sailors shoved off. The two boats rowed away from the island toward an unknown future.
The sun flickered on the restless waves just as it always did. The wind blew just as steadily as it always had. Yet everything had changed. They had been rescued from the island, only to be taken captive by barbarians.
Manjiro stared at the strangers when he thought they weren’t looking. Sometimes he caught them staring at him when they thought he wasn’t looking.
What do the details in this excerpt help readers to infer about the barbarians?
A. They are just as mean and monstrous as the fishermen expect them to be.
B. They are suspicious creatures who seem to be from a place other than Earth.
C. They have a plan to humiliate the fishermen and are waiting for the right time.
D. They are just as curious about the fishermen as the fishermen are about them.
Answer:
D
Step-by-step explanation:
"Manjiro stared at the strangers when he thought they weren’t looking. Sometimes he caught them staring at him when they thought he wasn’t looking."
"The fishermen exchanged frightened glances and whispered to one another,"
You hike up a mountain. You climb steadily for 2 hours, then take a 30-minute break for lunch. Then you continue to climb, faster than before. When you make it to the summit, you enjoy the view for an hour. Finally, you decide to climb down the mountain, but stop halfway down for a short break. Then you continue down at a slower pace than before. Sketch a graph of the situation. a. Height (feet) Time (hours) b. Is the graph discrete or continuous? Explain your reasoning.
Answer:
Continuous
Step-by-step explanation:
The graph is considered continuous due to the fact that it can take any amount of height, weight, and temperature. If it was discrete there would be a limit to your hike.

Find c, given that a + 18.2, B = 62, and C =48. Round answer to the nearest whole number. Do not use a decimal point or extra spaces in the answer or it will be marked incorrect
Answer:
[tex]c=14[/tex]
Step-by-step explanation:
a = 18.2
[tex]\angle B=62^{\circ}[/tex]
[tex]\angle C=48^{\circ}[/tex]
[tex]\angle A=180-(62+48)=70^{\circ}[/tex]
From sine rule we have
[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
[tex]\Rightarrow \dfrac{\sin A}{a}=\dfrac{\sin C}{c}[/tex]
[tex]\Rightarrow c=\dfrac{\sin C}{\sin A}a[/tex]
[tex]\Rightarrow c=\dfrac{\sin 48^{\circ}}{\sin 70^{\circ}}\times 18.2[/tex]
[tex]\Rightarrow c=14.4\approx 14[/tex]
[tex]\boldsymbol{\therefore c=14}[/tex].
Mark and Jen me at the beach yesterday July 31. Might go to the beach every third day in Django ceviche before three. How many times will they be at the beach on the same day over the next 30 days?
Answer:
The number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.
Step-by-step explanation:
Every third day implies that they both go the beach and then have a two day break, and then go the beach on the day after.
Put simply, every third day implies one day in three days.
Based on the above, the number times both Mark and Jen will be at the beach on the same day over the next 30 days can be calculated by dividing 30 by 3 as follows:
Number times both Mark and Jen will be at the beach = 30 / 3 = 10
Therefore, the number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.

Answer:
Expanded: 4x^2+20x+25
When simplified it changes back, (2x+5)^2
Step-by-step explanation:
Answer:
4x² + 20x + 25
Step-by-step explanation:
Given
(2x + 5)²
= (2x + 5)(2x + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x + 5) + 5(2x + 5) ← distribute both parenthesis
= 4x² + 10x + 10x + 25 ← collect like terms
= 4x² + 20x + 25

(04.03) The table shows the ratio of caramel corn to hot pepper corn in a bag. What is the constant of proportionality?
Hot Pepper Corn Caramel Corn
5 8
10 16
15 24
3
8
1.6
0.625
Answer:
0.625
Step-by-step explanation:
To solve the problem, we merely just divide the rates by each other. Ratios are just the fractions of two terms, after all.
Therefore, the answer would be 5/8, or 0.625.
To verify, we can use the other values given in your question.
10/16 is also an answer, but when you simplify, you get 5/8, which gives the same answer- 0.625.
You can do the same with the other ratios given.
15/24 simplified is 5/8, which, once again, is 0.625.
Thus, I can say with certainty that the answer is 0.625.

Answer:
perimeter of the following figure will be equal to 440 miles.
Step-by-step explanation:
perimeter refers to measure of total boundaries of a figure
hence perimeter will be the sum off all sides
so , P = 170 + 30 + 160 +80 = 440 miles

find the value of X round to the nearest tenth
Given:
In a right angle triangle triangle, the length of hypotenuse = 47 units.
One of the acute angle = 17°.
Opposite side of the given angle = X
To find:
The value of X. Round to the nearest tenth.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
A right triangle is crated with the help of dotted lines. In this triangle,
[tex]\sin (17^\circ)=\dfrac{X}{47}[/tex]
[tex]0.2923717=\dfrac{X}{47}[/tex]
Multiply both sides by 47.
[tex]0.2923717\times 47=X[/tex]
[tex]13.74147=X[/tex]
[tex]X\approx 13.7[/tex]
Therefore, the approximate value of X is 13.7 units.

Reduce the fraction: 40/1
please find the value of x in each parellogram and show work
Answer:
11.x=100
12.x=118
Step-by-step explanation:
using the interior angles theorem the space below x is 80 degrees
the space below 80 is x
Every paralellogram equals 360 degrees
add all angles and subtract from 360 to find x
80+80+x+x=160+x2
x2=200
x=100
Use the same thing for 12
62+62+X+X=360
124+2X=360
2X=236
x=118

find the measure of angle 1
Answer:
[tex]\displaystyle 70° = m\angle{1}[/tex]
Step-by-step explanation:
Consecutive Interiour Angles are supplementary, so set both expressions equivalent to one hundred eighty degrees:
[tex]\displaystyle 180° = [9x + 38]° + [6x + 22]° \hookrightarrow 180° = [60 + 15x]° \hookrightarrow \frac{120}{15} = \frac{15x}{15} \\ \\ 8 = x \\ \\ \\ [6[8] + 22]°; [48 + 22]° \\ \\ 70° = m\angle{4}[/tex]
As you can see, we plugged the x-value into the expression for the fourth angle because if you recall, you can tell that angles [tex]\displaystyle 1\:and\:4[/tex]are vertical angles, and accourding to the Vertical Angles Theorem, these angles are considered congruent, therefore seventy degrees is also the measure of the first angle.

Step-by-step explanation:
hope this helps :)
The slope of the line passing through (-4, -3) and (14, 0) is 1/6.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
The slope of the line passing through (-4, -3) and (14, 0) is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{0-(-3)}{14-(-4)} \\\\m=\frac{3}{18} \\\\m=\frac{1}{6}[/tex]
The slope of the line passing through (-4, -3) and (14, 0) is 1/6

Hey guys ( or gals ) I have no idea what to do please help me.
Answer:
Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.
You would have to find a GCF (greatest common factor) and multiply it out of the radical.
ex.
[tex]\sqrt{6}[/tex] = 2 x 2 x 2
when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2
2[tex]\sqrt{2\\}[/tex]
so [tex]\sqrt{6}[/tex] would be closest to the positive 2 on the number line and 2 notches.
[tex]\sqrt{11}[/tex]
is an irrational number, so it might fall into 3.3 if turned into a decimal.
