Answer:
Y = 1/2x+2
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
We know the slope
y = 1/2x +b
Substitute the point into the equation
0 = 1/2 (-4) +b
0 = -2+b
b=2
Y = 1/2x+2

A rectangular prism has a length of 9 in., a width of 4 in., and a height of 1 1/2in. The prism is filled with cubes that have edge lengths of 1/2 in. How many cubes are needed to fill the rectangular prism?
Hey there! :)
Answer:
432 cubes.
Step-by-step explanation:
Volume of rectangular prism: V = l × w × h
V = 9 × 4 × 1.5
V = 54 in³
Volume of cubes: V = s³
V = 1/2³
V = 1/8 in³
Set up an equation to solve for the # of cubes needed (x):
54 = 1/8x
Divide both sides by 1/8:
54 × 8/1 = x
x = 432 cubes.
BRAINLIEST!!! Mary went up the Old Tower taking 3 steps per second. Then she carefully came down from the tower taking 2 steps per second. It took Mary 25 seconds longer to come down than to go up. How many steps does the Old Tower have?
Answer:
The old tower has 65 steps.
(I think,)
Answer:
150 steps
Step-by-step explanation:
For every 6 steps going up it takes a extra 1 second to go down. Since it took Mary 25 seconds longer to get down you multiply 6 by 25 and you'll get 150 steps.

Hey there! :)
Answer:
f(x + 5/4) --> f(x) is translated 5/4 units left.
f(x) - 5/4 --> f(x) is translated 5/4 units down.
Step-by-step explanation:
Recall that a linear equation in transformations form is:
f(x) = ±a(b(x-h))+k
In this instance:
f(x + 5/4) the 'h' value is -5/4, meaning the graph is translated 5/4 units left.
f(x) - 5/4 has a 'k' value of -5/4, so the graph is translated 5/4 units down.

A department store sells logo shirts at an original price of $20.
Answer:
Answer is below.
Step-by-step explanation:
Macy forgot that a discount of 25% means the cost is multiplied by 75%.
Take the original price of the shirt, $20, times 75% for each month and times 50% for the employee discount.
20 x 0.75 x 0.75 x 0.50 = $5.63 is the price of the shirt for the employees using all of the discounts.

Answer:
The 3rd one
Step-by-step explanation:
You have already collected $20. You need at least $160, but having even more money would be great. You need $160, but any number to the right of 160 would be even better as your goal.

Answer:
12, -3.7, ⅓
(2nd, 3rd and 5th option)
Step-by-step explanation:
Constants are numbers without any variables with it.
x and y are the variables here.
-8 is the coefficient of y and hence it is not a constant.
*the value of a constant will not change
Note that the constant includes the symbol too, hence it is -3.7 and not 3.7.

Find the equation of the exponential function represented by the table below:
HELLPPP
Answer:
y = 4 [tex](\frac{1}{2}) ^{x}[/tex]
Step-by-step explanation:
For an exponential function in the form
y = a [tex]b^{x}[/tex]
Use ordered pairs from the table to find values of a and b
Using (0, 4 ), then
4 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), thus
a = 4, so
y = 4 [tex]b^{x}[/tex]
Using (1, 2 ) , then
2 = 4 [tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = [tex]\frac{1}{2}[/tex]
Thus exponential function is
y = 4 [tex](\frac{1}{2}) ^{x}[/tex]
Answer:
y = 4 (\frac{1}{2}) ^{x}

Answer:
∠ FGE = 52.5°
Step-by-step explanation:
The secant- secant angle is half the difference of the measures of the intercepted arcs, that is
∠ FGE = [tex]\frac{1}{2}[/tex] (arc BD - arc FE )
= [tex]\frac{1}{2}[/tex] × (135 - 30)°
= [tex]\frac{1}{2}[/tex] × 105°

this is a sketch of the curve with equation y=f(x) the vertex of the curve is at (2,-3)
Answer:
see explanation
Step-by-step explanation:
(a)
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
f(x) + 5 represents a shift up of 5 units, thus
(2, - 3 ) → (2, - 3 + 5 ) → (2, 2 )
(b)
Given f(x) then - f(x) represents a reflection of f(x) in the x- axis
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(2, - 3 ) → (2, 3 )
The vertex of the given curve is the minimum point on the curve.
The vertex of f(x) + 5 is (2,2)The vertex of -f(x) is (2,3)The vertex is given as:
[tex]\mathbf{(x,y) = (2,-3)}[/tex]
(a) The vertex of f(x) + 5
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,y + 5)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-3 + 5)}[/tex]
[tex]\mathbf{(x,y) \to (2,2)}[/tex]
Hence, the vertex of f(x) + 5 is (2,2)
(b) The vertex of -f(x)
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-(-3))}[/tex]
[tex]\mathbf{(x,y) \to (2,3)}[/tex]
Hence, the vertex of -f(x) is (2,3)

Hey there!
Answer:
2nd choice, The graph of g(x) is the graph of f(x) reflected in the x-axis, expanded vertically by a factor of 5, and translated 8 unit(s) down.
Step-by-step explanation:
Recall that the transformation form of a logarithmic function is:
y = ±alog(b(x-h))+k
Given g(x) = -5logx-8:
Negative in front of equation: reflection over the x-axis
'a' value of 5: expanded vertically by a factor of 5
'k' value of -8: translated 8 unit(s) down.

Lindsey lives 32 blocks from the grocery store. It takes her 9 minutes to walk 12 blocks. If she continues to walk at the same rate, how long would it take her to walk 32 blocks?
Answer:
if she countinues to walk at that rate it will take her 24 minutes to walk the 32 blocks
Step-by-step explanation:
i took the 12 blocks every 9 minutes and counted for a total of 36 blocks which would take 27 minutes then since we want to know how long it would take for her to walk 32 blocks I found how long it would take her to walk 4 blocks which is 3 minutes (12/3 = 4 9/3 =3) and i subtracted those 3 minutes from the 36 block walk giving you 24 minutes for 32 blocks
