B is also a way to find the y intercept
in function G the y-intercept is 6
and in the graph the y-intercept is 4
6 is greater than 4 so
Function G is larger
What is the equation of a circle with center (−3, 0) and radius 20?
Answer:
(x + 3)^2 + y^2 = 20^2
Step-by-step explanation:
If the center is (-3, 0), then the standard equation of a circle, (x - h)^2 + (y - k)^2 = r^2 becomes (x + 3)^2 + (y - 0)^2 = 20^2, or
(x + 3)^2 + y^2 = 20^2

A student is evaluating the expression below for n=3.7.12.8+6(n-0.5) in what order should the student do the steps?
Answer:
32
Step-by-step explanation:
The given expression is :
12.8+6(n-0.5)
We need to evaluate the expression for n = 3.7
Put n = 3.7 in the above expression.
12.8+6(3.7-0.5)
= 12.8+6(3.2)
= 12.8 + 19.2
= 32
So, the value of the given expression is equal to 32.

the surface area of the rectangular prism is given by formula S=2 (ab+bh+ah) find the value of h when a = 10, b=6 and s=440
Answer:
10
Step-by-step explanation:
440=2(60+6x+10x)
220=60+16x
160=16x
x=10
h=10
The required value of h is 10 which is determined by substituting the values of a = 10, b = 6, and s = 440 in the formula the surface area of the prism of S = 2 (ab+bh+ah).
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.
We have been given data as:
a = 10, b = 6 and s = 440
The surface area of the rectangular prism is given by the formula
⇒ S = 2(ab + bh + ah)
Substitute the values of a = 10, b = 6 and s = 440 in the above formula
⇒ 440 = 2(60 + 6h + 10h)
⇒ 220 = 60 + 16h
⇒ 220 - 60 = 16h
⇒ 160 = 16h
⇒ 16h = 160
⇒ h = 160/16
⇒ h = 10
Therefore, the required value of h is 10.

3. Choose the equation of the line parallel to the line 5 = -10x - 5y that passes through the point (-2,5). A y=-2x + 1 C y=x-5 By=-12x + 5 D y = 5x + 11
Answer:
y = -2x + 1
Step-by-step explanation:
The equation is in standard form, first, we need to convert it to slope-intercept form.
5 = -10x - 5y
5 + 10x = -5y
Divide both sides by -5 to isolate y variable.
y = -2x - 1
If the line is parallel, the slope remains the same.
To find the y-intercept, you need to plug the values of x and y into the equation, which is y = 2x + b
5 = -2(-2) + b
5 = 4 + b
1 = b
The equation is -2x + 1

Luis is making cookies. He needs 1 1/4 cup of sugar to make 12 cinnamon cookies and 1/2 cups of sugar to make 24 chocolate chip cookies. How many cups of sugar does he need to make both recipes?
Answer: 1 3/4 cups of sugar
Step-by-step explanation:
To make the first recipe, Luis needs 1 1/4 cup of sugar.
To make the second recipe, he needs 1/2 cup of sugar.
The number of cups of sugar that he need to make both recipes will be gotten by adding both cups of sugar together. This will be:
= 1 1/4 + 1/2
= 1 1/4 + 2/4
= 1 3/4
Therefore, 1 3/4 cups of sugar are needed

What is Factorizing?Brackets should be expanded in the following ways to factorize an expression
For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket
For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.
Given data ,
Let the expression be represented as A
Now , the value of A is
A = x² + x - 56
On factorizing the equation , we get
A = x² + 8x - 7x - 56
8x - 7x = 1
So , A = ( x - 7 ) ( x + 8 )
Hence , the expression is A = ( x - 7 ) ( x + 8 )

Answer:12 out of 9 chances
Step-by-step explanation:
Answer: 9/24 or 3/8(simplified).
Step-by-step explanation:
Okay first let's break it down.
The spinner has a 1/4 chance of landing on blue.
The spinner has a 1/2 chance of landing on red.
The spinner has a 1/4 chance of landing on green.
The spinner has a 3/4 chance of landing on red or blue
The spinner has a 3/4 chance of landing on red or green.
The spinner has a 1/2 chance of landing on blue or green.
A 6-sided die has a 1/2 chance of landing on either even or odd.
The question first asks the probability of spinning a red or blue.
So first, you need to know how many parts of the spinner of the four sections are red and blue. It's 3/4. There are 3 even numbers on a six-sided die so that's 3/6 or 1/2. Next, multiply these probabilities to get 9/24 or 3/8.
