Answer: 10 times 3 equals 30 and 7 times 18 equals 126. 126 plus 30 is 156 is the answer
Step-by-step explanation:math
There are two mystery numbers. The sum of 7 times the first number and 5 times the second number is -11. The sum of 10 times the first number and 8 times the second number is -20. What are the two numbers?
An exponential function has an initial value of 500 and a decay rate of 15%. Compare the average rate of change for the interval 0 < x < 4 to the average rate for the interval 4 < x < 8 What do you think will happen to the average rate of change for intervals beyond x = 8 ? Explain.
For 0<x<4, the average rate of change will be -60
For 4<x<8 the the average rate of change will be -31
And for the sentence (on savass in order is)
Stay negative, -31, decrease but at a slower rate
In this exercise we have to use the knowledge of functions to describe the average rates of each one of them, so:
For 0<x<4 will be -60
For 4<x<8 will be -31
First, we have to remember what an average rate means, like:
It is a measure of in what way or manner much the function altered for one, approximately, over that pause. It happen derived from the slope of the direct route joining the break's endpoints in contact the function's diagram.So we can say that:

Graph a line with a slope of 3 that goes through the point (1, 3).
X intercept and y intercept 20 POINTS
Answer:
Step-by-step explanation:
The slope intercept form of a line is y=mx+b where m is the slope and b is the y intercept. We are given a slope of three so
y=3x+b, using point (1,3) we can solve for b
3=3(1)+b, 3-3=0 so b=0 then our line is
y=3x
The x intercept is when y=0 and this occurs when x=0 or the point (0,0)
The y intercept occurs when x=0, this occurs when y=0 or the point (0,0)

Answer:
LCM of 9 and 15 is 45.
Step-by-step explanation:
What is the LCM of 9 and 15?
Find the prime factorization of 9.
Find the prime factorization of 15. 15 = 3 × 5.
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM: LCM = 3 × 3 × 5.
LCM = 45.

if a number y has a positive integer factors then y and 2z integer factors. Is it true? how?
Answer:
Given:
x is a factor of y --> , for some non-zero integer ;
y is a factor of z --> , for some non-zero integer ;
So, .
Question: is z even? Note that will be even if either or is even
(1) even --> either even, so the answer is directly YES or is even (or both). But if is even and as then z must be even too (one of the multiples of z is even, so z is even too). Sufficient.
(2) even --> as then as one of the multiples of z even --> z even. Sufficient.

2x^2=-10x+12
what are the solutions to this equation
Answer:
x = -6 and x = 1
Step-by-step explanation:
Move everything to the left side of the equation by subtracting (-10x + 12)
2x² = -10x + 12
2x² + 10x - 12 = 0
Divide each side by 2:
x² + 5x - 6
Find 2 factors of -6 that add up to 5. These factors are 6 and -1
x² + 5x - 6
(x + 6)(x - 1)
Set this equal to 0 and solve for x
(x + 6)(x - 1)
x + 6 = 0
x = -6
x - 1 = 0
x = 1
So, the solutions to the equation are x = -6 and x = 1
The solutions to the equation 2x² = -10x + 12 are x = -6 and x = 1.
To find the solutions to the quadratic equation 2x² = -10x + 12, we can rearrange the equation into standard quadratic form, which is ax² + bx + c = 0.
First, we move all the terms to one side of the equation:
2x² + 10x - 12 = 0
Next, we can solve this equation by factoring, completing the square, or using the quadratic formula. In this case, we'll use factoring.
Looking at the equation, we notice that all coefficients are even, so we can simplify the equation by dividing both sides by 2:
x² + 5x - 6 = 0
Now, we factor the quadratic expression:
(x + 6)(x - 1) = 0
By setting each factor equal to zero, we can find the solutions:
x + 6 = 0 --> x = -6
x - 1 = 0 --> x = 1
Therefore, the solutions to the equation 2x² = -10x + 12 are x = -6 and x = 1. These values make the equation true when substituted back into the original equation.
