Answer:
The graph in the attached figure
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
a is a coefficient
(h,k) is the vertex
In this problem we have
(h,k)=(1,-4)
substitute
we have
An x-intercept of (-1,0)
substitute and solve for a
The equation is
<u><em>Verify the y-intercept</em></u>
For x=0
The y-intercept is the point (0,-3) -----> is correct
using a graphing tool
see the attached figure
Answer: 1
Step-by-step explanation:
Answer:
125 is 80% of 156.25
Working out percentages
We have, 80% × x = 125
or,
<u>80
</u>
100
x = 125
Multiplying both sides by 100 and dividing both sides by 80,
we have x = 125 ×
<u>100
</u>
80
x = 156.25
If you are using a calculator, simply enter 125×100÷80, which will give you the answer.

Answer:
A+3B=4+5r
Step-by-step explanation:
Given that,
A = 1+r+7r
B = 1-r
We need to find an expression that is equal to A+3B.
Putting the values of A and B in A+3B, we get :
A+3B = 1+r+7r + 3(1-r)
=1+8r+3-3r
=(1+3) +(8r-3r)
=4+5r
Hence, the values of A+3B equals 4+5r.
5/17 means 5 parts of 17
17-5=12
So if 5/17 is shaded, 12/17 is not.
<em>Answer: 12/17</em>
