Answer:
B. g(x)=(x+7)^2-3
Step-by-step explanation:
Vertex form is F(x)= a(x-h)^2+k
a is the reflection
h and k are the vertex (x,y) = (h,k)
in this case there is no shrink or stretch (a)
if it is translating left or right it is "h". In this case it is translated left so its -7. However if you look at vertex form it is "x-h" so -7-7= +7
If it translating up or down it is "K". In this case it is translated down so its -3.
If it was translated up or right then its positive. If it was translated down or left its negative.
After you figure out what h and k are then you just plug it in. h=-7, k=-3
so the answer in vertex form is, g(x)=(x+7)^2-3

For a moving object, the force acting on the object varles directly with the object's acceleration. When a force of 45 N acts on a certain object, the acceleration
of the object is 5 m/s?. If the force is changed to 63 N, what will be the acceleration of the object?
Answer:
acceleration,A = 7
Step-by-step explanation:
F = kA
First expression: 45 = 5k, k = 9
therefore, when F = 63, A = 63/9 = 7

Which rectangular equation represents the parametric equations x = t Superscript one-half and y = 2t? y = 4x2 y = 2x2 y = StartRoot 2 x EndRoot y = 2 StartRoot x EndRoot
The rectangular equation which represents the parametric equations x =t^(1/2) and y = 2t is; y=2x².
Generating equations from Parametric equationsAccording to the task content;
It follows that the parametric equations given are; x =t^(1/2) and y = 2t.
Since x =t^(1/2), then it follows that; x² = t.
Therefore, by substituting x² for t in y= 2t, then we have; y = 2x².

Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.
A. 2 12/16 = 2 3/4 Ib
B. 2 2/8 = 2 1/4 Ib
C. 2 14/16 = 2 7/8 Ib
D. 2 1/2 Ib
The measured weight is (2 + 3/4) lb, so the correct option is A.
How to read the measure?
First, we can see that the needle is between the 2lb and 3lb mark, so we know that we have a measure between these two values.
Now, let's count the number of small lines between the needle and the 2lb mark. There are 12 marks (the 12th is below the needle). Then the measure will be:
(2 + 12/16) lb.
Now we want to simplify the fraction. If we divide both numerator and denominator by 4, we get:
12/16 = 3/4
Then the weight is:
(2 + 3/4) lb
Then the correct option is A.

which is a better value? 1 pound of apples for 2.15 or 3 pounds of apples for 5.76
Answer:
From what i've gotten on another answer on brainl It might be 3 pounds of apples for 5.76. On another question i've resarched i've also gotten $7.91.
Step-by-step explanation:
Sorry if none of these answers have helped you.
Answer:
The 2nd offer - 3 pounds of apples for 5.76
Step-by-step explanation:
1. Find the unit price for the 1st offer.
The unit price is 1 pound of apples for $2.15. <-- given information
2. Find the unit price for the 2nd offer.
We can set up a proportion to find the unit price.
3 pounds / $5.76 = 1 pound / $x
Let x = how much 1 pound of apples are for the 2nd offer
Cross multiply
3 · x = 5.76 · 1
Simplify
3x = 5.76
Divide both sides by 3 to isolate x
x = 1.92 = $1.92 for a pound of apples (2nd offer)
3. Compare the two offers' unit prices.
$2.15 <-- 1st offer
$1.92 <-- 2nd offer
The second offer is the better value because it costs less for each pound of apple.

The length of a rectangle is 3 inches more than it’s width.If the perimeter is 42 inches,find the dimensions of the rectangle.
Answer: Length = 9 in
Width = 12 in
Step-by-step explanation:
Length L = 3 + W
Perimeter P = 42 in
Perimeter = 2L + 2W
plugin values:
42 = 2(3 + W) + 2W
42 = 6 + 2W + 2W
42-6 = 4W
W = 36 / 4
W = 9
solve L by substituting the value of W=9 into the equation:
L = 3 + W
L = 3 + 9
L = 12
therefore, the dimensions of the rectangle:
Length = 9 in
Width = 12 in
Answer:
Answer:
length = 9 in
width = 12 in
Step-by-step explanation:
