C) They satisfy equation A but not equation B
________________
EXPLANATION
4y - 3x = 16
4(0.25) - 3(-5) = 16
1 -3(-5) = 16
1 + 15 = 16
16 = 16
-x - 8y = 3
-5 - 8(0.25) = 3
-5 - 2 = 3
-7 = 3
Doesnt solve equation B
(Please mark me brainliest it would be much appreciated)
Answer:
y=7x-6
Step-by-step explanation:
Use point-slope equation.
y-y1=m(x-x1)
y-8=7(x-2)
y-8=7x-14
y=7x-6
Answer:
See sample table below.
Step-by-step explanation:
The function is given as :
f(x) = 3ˣ
A table of values can be formed as ;
x <u>calculations</u> f(x)

-3 3⁻³ 0.0370
-2 3⁻² 0.1111
-1 3⁻¹ 0.3333
0 3⁰ 1.000
1 3¹ 3.000
2 3² 9.000
3 3³ 27.00
4 3⁴ 81.00
We need to find what fraction of the garden is cherry trees so we add the proportion of the other kinds of trees and subtract this from 1 like so:
1/2 + 1/4 + 1/6 = 11/12
1 - 11/12 = 1/12
This means that 1/12 of the all trees in the garden are cherry trees;
We know that there are 200 cherry trees;
If we let x = the total number of trees in the garden
Then, we can say:
1/12 * x = 200
x = 200 * 12
x = 2400
There are 2400 trees in the garden.
The percent of the discount is 28 percent off
