The green shaded region does not represent the
solution to the system of linear inequalities given
below. Explain why not.
y²2
35x+2y= 20
Answer:
Step-by-step explanation:
Region represented by the inequality y ≥ 2 will be the area above the dark line y = 2.
Equation of the other line is,
3.5x + 2y ≤ 20
2y ≤ 20 - 3.5x
y ≤ -1.75x + 20
Shaded region representing the solution of the inequality will be below the solid line y ≤ -1.75x + 20.
Therefore, solution of the system of inequalities will be the common region of both the colors in the graph attached.
Graph of the question will not represent the solution of the system of inequalities.
Answer:
The blue line should be solid because the inequality has “or equal to.” The green shading should be on the other side of the blue line. The blue line should be part of the solution set.

Answer:
Robert is 10 and his dad is 40 years old
Step-by-step explanation:
We have (4x+5)=3(x+5)
4x+5=3x+15
x=10.
Roberts is 10 years old and his father is 40 years old.
Answer:
Step-by-step explanation:
Roberts's father=4x
Robert=x
After 5 years, the ages will be
4x+5 and x+5 because we just simply add 5 years to their ages
It says that the father will be 3x older. So,
3(x+5)=4x+5. --this is the equation
3x+15=4x+5
-5 -5
3x+10=4x
-3x -3x
x=10

Answer:
c 25
Step-by-step explanation:
The exponents cancel out and leaves you with 5 × 5. which is 25
Forty-five is six more than three times a number.
Answer:
13
Step-by-step explanation:
45 - 6 = 39/3 = 13
Answer:
Forty-five is six more than three times 13.
Step-by-step explanation:
First, you have to set up the equation. We know 45 equals three times a number, 3x, plus 6.
45 = 3x + 6
Subtract 6 from both sides.
39 = 3x
Divide by 3 to isolate the x, and you get 13. Hope that helps!

Answer: X = -7
Step-by-step explanation:
the number is represented as X
6x + 10 = 4x - 4
solve your equation by subtracting 10 on both sides to make -4 -14
6x = 4x - 14
subtract 4x on both sides to get 2x
2x = -14
divide -14 by 2x
x = -7
Check it by plugging it in the equation
-42 + 10 = -28 - 4
-32 = -32

Evaluate the following expression x^2 - 4x + 2 when x = -2
Answer:
-2
Step-by-step explanation:
sub x = -2 into X^2 - 4 x + 2
-2^2 - 4(2) + 2
= 4 - 8 + 2
= -4 + 2
= -2
Answer:
14
Step-by-step explanation:
Well since we know that x= -2 we can plug it into the equation
-2^2-4*-2+2
Now we can solve
-2^2 - 4*2+2
= 14

Find the slope of the line that passes through (8,4) and (5, 3).
Answer:
The answer is
[tex] \frac{1}{3} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}\\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(8,4) and (5, 3).
The slope is
[tex]m = \frac{3 - 4}{5 - 8} = \frac{ - 1}{ - 3} = \frac{1}{3} \\ [/tex]
We have the final answer as
[tex] \frac{1}{3} \\ [/tex]
Hope this helps you
Step-by-step explanation:
Hey there!
Here;
The given coordinates are(8,4) and (5,3).
Use slope formulae.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{3 - 4}{5 - 8} [/tex]
Simplify it to get answer.
[tex]m = \frac{ - 1}{-3} [/tex]
Therefore the slope is, 1/3.

Write a function rule for the table.
OC= 220 + 12
Oc= 220
Oc= 220 + 22
O c = 120 + 22
Answer:
c = 22o + 12
Step-by-step explanation:
As input values increase by 1, output values increase by 56-34=22. The output value for o=1 is 12 more than 22o, so the function rule seems to be
c = 22o +12
__
Based on answer choices, we assume that input is o, and output is c. '0' is not a variable.

Convert the following angle from degrees to radians. Express your answer in simplest form. 690∘
23π / 6 radians is equivalent to the 690-degrees.
To convert degrees to radians, we use the formula:
radians = degrees × π / 180
Therefore, for 690 degrees:
radians = 690 × π / 180
Simplifying this expression:
radians = 23π / 6
Therefore, 690 degrees is equivalent to 23π / 6 radians.

Step-by-step explanation:
Kelly runs a distance of 100 metres in a time of 10.52 seconds.
The distance of 100 metres was measured to the nearest metre.
The time of 10.52 seconds was measured to the nearest hundredth of a second.
Write down the upper bound for the distance of 100 metres.
Answer:
Upper bound for distance = 100.49. This is the highest number that you can round up to get 10.52.
Lower bound for time = 10.515 seconds. This is the lowest number that you can round up to get 10.52.
Upper bound for average speed = Upper bound for distance divided by upper bound for time.
100.49/10.5249 = 9.548 seconds.
Lower bound for average speed = Lower bound for distance divided by lower bound for time.
99.5 / 10.515 = 9.463 seconds.
Step-by-step explanation:
Hope this helps you out.
The upper bound for the distance of 100 metres is 100.4 meters.
What is meant by rounding off?Rounding off means a number is made simpler by keeping its value intact but closer to the next number.
Given:
Kelly runs a distance of 100 metres in a time of 10.52 seconds.
The upper bound represents the highest number, to which round off can be done to the nearest unit.
We have distance of 100 metres
So, the upper bound for the distance is 100.4 meters.
Hence, the upper bound for the distance is 100.4 meters.

1) If 2x + 3y = 12 and xy = 6, find the value of 4x2 +9y2.
Answer:
72
Step-by-step explanation:
Given that 2x + 3y = 12 , then
(2x + 3y)² = 12² = 144 ← distribute left side using FOIL
4x² + 12xy + 9y² = 144 ( subtract 12xy from both sides )
4x² + 9y² = 144 - 12xy = 144 - 12(6) = 144 - 72 = 72
