f(-8) = 2{(-8) - 3} + 4
= 2{-11} + 4
= -22 + 4
= -18

Which graph best represents the following equation?
y + 3 = |x – 5|
Answers
Answer:
This one
Step-by-step explanation:
The graph of the function y + 3 = |x - 5| is the first diagram given in the options.
What is modulus function ?A modulus function always outputs positive numeric value irrespective of the sign of the input.
According to the given question we have to determine the graph of y + 3 = | x - 5 |.
So, y + 3 = | x - 5|
y = | x - 5 | - 3.
Now to obtain the vertex of the graph we'll set x -5 = 0 .
x = 5 and that corresponds to y value of -=3.
So, the vertex of the graph is (5,-3).
Now to plot the function we'll select some values of less than and greater than 5.
When x = 2 , y = 0. x = 4 , y = 2. x= 6 , y = -2. x = 8 y = 0.

What is Y + 4 = -3 (x +1) in standard form?
Answers
-3x - y = 7
Explanation:
the standard form of an equation is written as Ax + By = C, where A, B, and C are integers.
first, distribute -3:
y + 4 = -3x - 3
then get x and y on the same side and the number on the other side for standard form.
add 3 to both sides:
y + 7 = -3x
subtract y from both sides:
7 = -3x - y
Answer:
-3x - y = 7
first, distribute -3:
y + 4 = -3x - 3
then get x and y on the same side and the number on the other side for standard form.
add 3 to both sides:

What is the image point of ( 4 , − 6 ) (4,−6) after a translation right 5 units and up 4 units?
Answers
Answer:
(9,-2)
Step-by-step explanation:
5 is the x coordinate, and 4 is the y coordinate. When you go right a certain amount of units, you add those units to your x coordinate. If you were to go left a certain amount of units, you'd subtract them. Since we're going right, 5 + 4 = 9. When you go up a certain amount of units, you add those units to you y coordinate. If you were to go down a certain amount of units, you'd subtract them. Since we're going up, -6 + 4 = -2. So, x = 9 and y = -2, or (9,-2)

Under her cell phone plan, Janelys pays a flat cost of $46.50 per month and $5 per gigabyte. She wants to keep her bill under $70 per month. Write and solve an inequality which can be used to determine gg, the number of gigabytes Janelys can use while staying within her budget.
Answers
Answer:
less than 4.7 gigs
Step-by-step explanation:
The cost of Janelys's cell phone plan will be the sum of the flat cost and the product of the per-gig cost and the number of gigs of data she uses.
y = 46.50 +5g
She wants this to be less than $70 per month, so we can find the constraint on her data usage from ...
46.50 +5g < 70
5g < 23.50 . . . . . . . . subtract 46.50
g < 4.7 . . . . . . . . . . divide by 5
Janelys must use less than 4.7 gigs of data to stay within her budget.
Rectangle LMNP with vertices L(-2, 7),
M(2,3), N(0, 1), and P(-4, 5):
(a) Translation: (x, y) - (x + 6, y-8)
(b) Reflection: in the y-axis
Answers
Answer:
L’ is (-4,-1)
M’ is (-8,-5)
N’ is (-6,-7)
P’ is (-2,-3)
Step-by-step explanation:
Here, we want to from new vertices by translation followed by reflection;
When we reflect , we simply change the sign of the x-coordinates if we are reflecting over the y-axis
We proceed as follows;
1. L (-2,7)
Translation will be (-2 + 6, 7-8) = (4,-1)
Reflection will be ( -4,-1)
so L’ is (-4,-1)
2. M (2,3)
Translation will be
(2 + 6, 3-8) = (8,-5)
Reflection will be ( -8,-5)
So M’ is (-8,-5)
3. N (0,1)
translation will be
( 0 + 6, 1-8) = (6,-7)
Reflection will be ; (-6,-7)
4.P (-4,5)
Translation will be (-4 + 6, 5-8)
= (2, -3)
Reflection will be;
(-2, -3)
P’ = (-2,-3)

what is g(-4) + f(1)?
Answers
If f(x) = -4x - 5 and g(x) = 3 - X,the value g(-4) + f(1) is equal to -2.
The function f(x) is f(x)=-4x-5
The function g(x) is g(x)=3-x
g(-4)=3-(-4)=3+4=7
f(1)=-4(1)-5=-9
g(-4)+f(1)=7+(-9)=7-9=-2

The function of g is being applied to the function of x, in this case.

Answers
Answer:

Step-by-step explanation:
since we know that when 20 minutes have passed, the minute hand will have moved 4 intervals (i.e. from 12 to 4), and each interval is 30 degrees by measurement. So 4 intervals have a degree measurement of 120 degrees, which is 1/3 of the whole circle (clock). since there isn't any notation on whether pi is taken as 3.14 or 22/7 or whatsoever, you can just say that it has moved (5x2)pi x 1/3 = 3 1/3 pi inches
