Answer: B ?
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Use the vertical line test to see if it a function. If the vertical line passes through 2 or more points, then it not a function. If only one point, it is a function.
Rearrange then factorise x^2-5x+19=5x+3
Answer:
x = ±4i or x = ±√-16
Step-by-step explanation:
x² - 5x + 19 = 5x + 3
x² + 16 = 0
x² = -16
x = ±√-16 (a negative square root is an imaginary number)

A flower pots space and six size they're all the same length. Each side measures X -6 units. The bases perimeter is 78 units. What is the value of X
Answer:
x = 19
Step-by-step explanation:
The shape of the flower base has six sides of equal lengths. This means that the flower base is a regular hexagon. A regular hexagon is a closed polygon with six equal sides and six equal angles.
Each side of the base measures x - 6, and the perimeter of the base is 78 units.
Length of each side = x - 6
The total length of the base = perimeter of the base.
The total length of the base is gotten by summing all the sides of the base. Since the base has 6 sides, therefore the total length of the base = 6(x - 6). Hence:
Perimeter of base = 6(x - 6)
78 = 6x - 36
6x = 78 + 36
6x = 114
x = 114 / 6
x = 19
Length of each side of base = x - 6 = 19 - 6 = 13 units
WHICH STATEMENT IS TRUE?
Answer:
Step-by-step explanation:
The perimeter of the field is 6times the perimeter of the playgroud.

Answer:
Q2: slope = -½
Q3: slope = 1
Step-by-step explanation:
If the equation of the line is in the form y = mx+b, then m is the slope of the line and b is the y-intercept (the point where the line crosses the x-axis).
y = -½x, so the slope of the line is -½
y = x+15, so the slope of the line is 1

X = 5
x = 4
x = 12
x = 20
Answer:
X = 5
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
The scale factor of this shape is of 4
From 12 to 3, you divide by 4
So now, you need to divide 20 by 4 to get what x is, and 20 ÷ 4 is 5

Carl went to the toy store with a total of $17.25. He wanted to buy
action figures costing $1.83 each (price includes tax). What is the
maximum number of figures that he can buy?
Answer:
Step-by-step explanation:
Just divide 17.25 by 1.83 and you will get the answer. You'd get 9.4 but you can't have .4 of something so it is just 9.

Answer:
y=x+4
Step-by-step explanation:
The slope of the graph is 1x or just x. The y-intercept of the graph is 4 because the line intercepts with the y axis at 4. So your equation is y=x+4.

Answer:
12.65
Step-by-step explanation:
Just use the pythagorean Theorem
Answer:
12.65
Step-by-step explanation:
Use the Pythagorean Theoram to answer this question.
a^2 + b^2 = c^2
a^2 + 6^2 = 14^2
a^2 + 36 = 196
-36 -36
_____________
a^2 = 160
then you square root both sides of the equation to get 12.65
Jack has twice as many dimes as quarters. If the total value of the coins is $6.30, how many dimes does he have?
Answer:
Number of dimes = 28
Step-by-step explanation:
Given that:
Worth of coins = $6.30 = 6.30 * 100 = 630 cents
Let,
x be the number of dimes
y be the number of quarters
According to given statement;
x = 2y Eqn 1
10x+25y = 630 Eqn 2
Putting x = 2y in Eqn 2
10(2y) + 25y = 630
20y + 25y = 630
45y = 630
Dividing both sides by 45
[tex]\frac{45y}{45}=\frac{630}{45}\\y=14[/tex]
Putting y=14 in Eqn 1
x = 2(14)
x = 28
Hence,
Number of dimes = 28

Dan draws a circle with a radius of 8 inches. Question 1 Part A: What is the circumference of Dan's circle, inches? If needed, round your answer to the nearest hundredth. Enter your answer in the box.
Answer:
The circumference of Dan's circle is approximately 50.27 inches.
Step-by-step explanation:
The length of the circumference ([tex]s[/tex]), measured in inches, is determined by the formula:
[tex]s = 2\pi\cdot r[/tex] (1)
Where [tex]r[/tex] is the radius, measured in inches.
If we know that [tex]r = 8\,in[/tex], then the length of the circumference is:
[tex]s = 2\pi\cdot (8\,in)[/tex]
[tex]s \approx 50.27\,in[/tex]
The circumference of Dan's circle is approximately 50.27 inches.

The exponential function is given by N=4(2)ˣ
What are exponents?Exponent is a mathematical operation, written as an. Here the expression an involves two numbers, the base 'a and the exponent or power 'n'. Exponents are used to simplify algebraic expressions.
Given here: A particular type of cell doubles every hour and initially there were 4
let x be the number of hours then we have the exponential function
N= 4×2ˣ
Now for x=0 hours we have
N=4
which is the initial amount
similarly for x=1 we have
N=4×2
=8 which is double from the initial amount in hour
Thus the function that can describe the relationship is N=4(2)ˣ
