Answer:
k = 29
Step-by-step explanation:
(5k -3) + (9+k) = 180
5k-3+9+k = 180
6k + 6 = 180
6k = 180 - 6 = 174
k = 29
The function ought to be represented as; m(t) = 7t + 25 where t is the number of yards that she mows.
<h3>What is a linear function?</h3>
The term linear function refers to a function that yields a straight line graph when it is plotted. Now we know that a linear function would not contain an exponent that is greater than one.
In this case, we know that the question states that she charges a base fee of $25 and $7 for every hour she mows thus the function ought to be represented as; m(t) = 7t + 25 where t is the number of yards that she mows.

Answer:
1,1
Step-by-step explanation:
Substitute 1 and 1 for x and y
x + y = 2
(1) + (1) = 2 ----> Works
x + 3y = 4
(1) + 3(1) = 4
1 + 3 = 4 ------> Works

Answer:
x=-3,x=9
Step-by-step explanation:
x^2-6x-20-7=0
x^2-6x-27=0
x^2-(9-3)x-27=0
x^2-9x+3x-27=0
x(x-9)+3(x-9)=0
(x+3)(x-9)=0
x=-3,x=9
Answer:
x = -2, x = 2
Step-by-step explanation:
The denominator factors as ...
x^2 -4 = (x -2)(x +2)
The numerator has no factors that cancel either of these, so the function will have vertical asymptotes where the denominator is zero: at x = -2 and x = 2.
