9-2x+35
first you want to get rid of the number. so you subtract 9 on both sides. Think of this as a balance scale, what you do on one side must be done on the other.
9-2x+35
-9 -9
-2x= 26
you always want to do the opposite, so since this was positive 9 you subtract so the 9 is gone.
-2x=26
/-2 /-2
you divide each side by -2 and you get
x=-13
since a negative divided by a positive is a negative
A composite number is a number that's not prime. A prime number is a number who only has 2 factors (1 and itself). A composite number has multiple factors.
For example;
7 is prime, as the factors of 7 are only 1&7.
14 is composite, as there are 4 factors (more than 2); 1&14, 2&7.
91 is composite, as it has the following factor pairs; 1&91, 7&13.
139 only has 1&19, making it prime.
13 only has 1&13, making it prime.
29 only has 1&13, making it prime.
Your answer is A.) 91.

The coordinate set (0, 0), (2, 1), (4, 2), (6, 3) represents a straight line. Since the first point is (0, 0) the y-intercept is 0. Now, lets solve for the slope (we can use any of the four points to solve).
Slope formula: y2-y1/x2-x1
= 2-1/4-1
= 1/2
Now that we know what the slope is, we can write the equation of the line.
Slope intercept form: y = mx + b (m = slope and b = y-intercept)
y = 1/2x
Lets find the exponential equation for the line.
y = ab²
1 = ab²
1/a = ab²/a
1/a = b²
√1/a = √b²
√1/a = b

Answer:
Step-by-step explanation:
- 20 + 2 < x/3 - 8
- 22 + 8 < x /3
- 30 < x /3
- 30*3 < x
- 90 < x
- x > 90
Correct choice is C
