Answer:
Step-by-step explanation:
To isolate the term of x from one side of the equation, you must multiply by a polynomial.
<u>You have to solve with parentheses first.</u>
<u>Solve.</u>
x(-5x)=-5x²
3*3x²=9x²
3(-5x)=-15x
3(-10)=-30
<u>Then, rewrite the problem down.</u>
<u>Combine like terms.</u>
<u>Add/subtract the numbers from left to right.</u>
-5x²+9x²=4x²
<u>Solve.</u>
<u>Then rewrite the problem.</u>
- <u>Therefore, the correct answer is 3x³+4x²-25x-30.</u>

y = - 4x + - 8 is equation of slope-intercept form.
What is in slope-intercept form?
- Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
- Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.
the equation of slope - intercept form
y = mx + c
( -1 , -4 ) is point shown in graph
slope = -y/x
= - ( -4)/-1 = 4/-1 = -4
- 4 = -4 * - 1 + c
- 4 = 4 + c
c = - 4 - 4 = - 8
put value of c in the equation of slope - intercept form
y = - 4x + - 8

Step-by-step explanation:
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
The difference is a2 - a1 = 31 - 24 = 7
n = 500
a500 = a1 + (500 - 1) * 7
a500 = 24 + 499 * 7
a500 = 24 + 3493
a500 = 3517
