It means try to figure out the question by using the things with the same variable. so if it says “x + 6 = 13 and x = 8 then you use the x = 8 to figure out x + 6 = 14
Answer:
The y-intercept is (0, -1)
The exponential function that gives the relationship between y and t is:
.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
In this problem, the parameters are given as follows:
A(0) = 370000, r = 0.06.
Hence the equation is:

I don't know which language you use those, so I assume that you use c++
for (int i = 1; i <= userNum; i++)
{
summedValue = summedValue + i;
i = i + 1;
}
Substitute y = 3x + 15 to the equation -4x + 7y = 20:
-4x + 7(3x + 15) = 20 <em>use distributive property</em>
-4x + (7)(3x) + (7)(15) = 20
-4x + 21x + 105 = 20 <em>subtract 105 from both sides</em>
17x = -85 <em>divide both sides by 17</em>
x = -5
Substitute the value of x to the equation y = 3x + 15:
y = 3(-5) + 15
y = -15 + 15
y = 0
<h3>Answer: x = -5 and y = 0</h3>
