Answer:(a=5,b=3)
7a-3b = 26--------(1)
a + 2b =11---------(2)
on mutlplying by7 in eq 2
= 7a+14b=77-------(3)
from eq(1) and (3) (on substracting)
7a+14b=77
7a-3b=26
________
=-17b=51
b=51/17
b=3
on putting value of b in eq 1
7a-3b = 26
=7a-9=26
7a=35
a=5
Step-by-step explanation:

The equation would be 55h+40=c
h-hours
40-Initial value-Price paid at start
c-total cost
so if you plug the numbers in, 55h+40=190
Subtract 40 from both sides, 55h=150
Divide both sides by 55, h=150/55
150/55=<span>2.72727272727
and that rounds to 2.73</span>

Step-by-step explanation:
<u>Given function:</u>
To graph the line we need two points
One of the easy points is the y-intercept:
Another point can be taken depending on the slope. With the slope of -3, we select x = 2 and find its y- coordinate:
- y = -3(2) + 4 = -6 + 4 = -2
So we have points
Plot these points and connect with the line and we are done.
Answer:
A
Step-by-step explanation:
we have given that .
we need to express this interms of power of x .
we know that .
in place of n we have 2 .so .
so this will be the expression interms of power of x .
