Answer:
Yes
Step-by-step explanation:
Because 9, 12, and 15 are Pythagorean triples
<u><em>(The Explanation):</em></u> What we are given is that the car drives 45 miles each hour. Furthermore, you need to multiply the amount of hours desired to the miles to get a total mile.
<u><em>(Step-By-Step Instructions):</em></u>
<em>45(4) and 45(20) </em> Multiply
<u><em>The Answers:</em></u> 4 hours = 180 miles / 20 hours = 900 miles
2. I think the answer is 24
subracting the last 2 inequalities we get
6x + 7y <= 42
3x + 2y <= 18 subtract:_-
3x + 5y <= 24
Answer:

Step-by-step explanation:
We are asked to find the equation of a line given a point and the slope. We will use the point-slope formula.

In this formula, m is the slope and (x₁, y₁) is the point the line passes through. The slope of this line is -4 and the line passes through (-2,5).
Substitute the values into the formula.


We are finding the equation of the line, so we should find the slope-intercept form or y=mx+b ( where m is the slope and b is the y-intercept).We must isolate the variable y on one side of the equation.
First, distribute the -4 on the right side of the equation. Multiply each term inside the parentheses by -4.


5 is being subtracted from y. The inverse operation of subtraction is addition, so we will add 5 to both sides of the equation.


The equation of the line is y= -4x -3. The slope of the line is -4 and the y-intercept is -3.
