f(x)=7x+2
f(-1)=7(-1)+2=-7+2=-5
f(3)=7(3)+2=21+2=23
f(5)=7(5)+2=35+2=37

Given f(x)=10x+4 and g(x)=3x-8
f(x)+f(x)=(10x+4)+(3x-8)=13x-4
13x-4
Question 49
f(x)=x²-3x and g(x)=4x⁵
f(x)*g(x)=(x²-3x)(4x⁵)=4x⁷-12x⁶
4x⁷-12x⁶
Question 50
(0,3)
f(x)=-2x/3 + 2
f⁻¹(x)=-3x/2+3
f⁻¹(0)=3

Answer:
$7282.8
Step-by-step explanation:
You multiply 7000*0.02
Add 140 (answer to this^) to 7000
7140*0.02
^add this answer to get 7282.8
The integers that make the linear equation false are:
3, 78, and 126
We found that by evaluating the equation in all the options.
<h3>Which integers make the equation false?</h3>
Here we have the linear equation:
8m - 15 = 5m + 63
And the possible solutions are:
S: {3, 26, 78, 126}
To see which of these integers make the equation false, we can replace the value of m by the given values and see when the equation is false (the number in the left is different to the one in the right).
if m = 3
8*3 - 15 = 5*3 + 63
9 = 78 this is false.
if m = 26
8*26 - 15 = 5*26 + 63
193 = 193 this is true.
if m = 78
8*78 - 15 = 5*78 + 63
609 = 453 this is false.
if m= 126
8*126 - 15 = 5*126 + 63
993 = 693 this is false.
So the integers that make the equation false are:
3, 78, and 126.
