Mathematics
1 answer:
Gemiola [76]3 years ago
7 0

Answer:

C) 3/4

Step-by-step explanation:

The equation for rate of change is (y2-y1)÷(x2-x1)  These numbers come from two ordered pairs off the table of your choice (x1,y1) (x2,y2). I used the first two rows of the table so my two order pairs are (-8,-12)=(x1,y1) and (8,0)=(x2,y2) Next i plugged the ordered pairs into the equation:

0-(-12) ÷ 8-(-8)        

In both the numerator(top) and the denominator(bottom) are subtracting a negative which is the same as adding so the fraction is 12/16. This can be further simplified by dividing the top and bottom by 4 to get the final answer of 3/4

Find the 12th term of the sequence -15,-9,-3, 3
Reika [66]
First term (a) = -15
common difference(d)= -9-(-15)
= -9+15=6
So,
12th term(a12)= a +(n-1)d
= -15+(12-1)×6
= -15 + 11×6
= -15+66
= 51

1. The spinner shown has six congruent sections.
kondaur [170]

Answer:

B

Step-by-step explanation:

The probability of obtaining a 3 is

P(3) = \frac{1}{6}

Then after 30 spins the predicted number of times it should land on 3 is

30 × \frac{1}{6} = 5

What is the solution to 3(–3x + 9) = −18?
Rus_ich [418]

Answer:

x = 5 (If solved algebraically)

No Solution (If the parentheses are absolute value lines)

Step-by-step explanation:

Result when solving this way: 3|-3x + 9| = -18

1) Divide both sides by 3
|-3x + 9| = -18/3

2) Simplify 18/3 to 6

|-3x + 9| = -6

3)  Break down the problem into these 2 equations.

-3x + 9 = -6

- (-3x + 9) = -6

4) Solve the 1st equation: -3x + 9 = -6

- Subtract 1 from both sides.

-3x = -6 - 9

-Simplify -6 - 9 to -15.

-3x = -15

-Divide both sides by -3.

x = -15/-3

- Two negatives make a positive.

x = 15/3

- Simplify 15/3 to 5.

x = 5

6)  Solve the 2nd equation:  - (-3x+ 9) = -6

1 - Remove parentheses

3x - 9 = -6

2 - Add 9 to both sides

3x = -6 + 9

3 - Simplify -6 + 9 to 3.

3x = 3

- Divide both sides by 3.

x = 1

6) Collect all solutions.

x = 1,5

7) Check solution.

When x = 1, the original equation 3|-3x + 9| = -18 does not hold true.

We will drop x = 1 from the solution set.

8) Check solution.

When x = 5, the original equation 3|-3x + 9| = -18  does not hold true.

We will drop x = 5 from the solution set.

9) Therefore,

No solution exists.

Result when solving algebraically:

Simplifying

3(-3x + 9) = -18

Reorder the terms:

3(9 + -3x) = -18

(9 * 3 + -3x * 3) = -18

(27 + -9x) = -18

Solving

27 + -9x = -18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + -9x = -18 + -27

Combine like terms: 27 + -27 = 0

0 + -9x = -18 + -27

-9x = -18 + -27

Combine like terms: -18 + -27 = -45

-9x = -45

Divide each side by '-9'.

x = 5

Simplifying

x = 5
