Answer:
Step-by-step explanation:
<em>START:</em> 4x + 10 = - 26 ⇔ 4x = - 36 ⇔ <em>x = - 9</em>
x + 13 = 9 ⇔ x = - 4 ⇔ <em>x = 8</em>
x - 9 = 27 ⇔ x = 36 ⇔ <em>x = 48</em>
9 - 2x = 35 2x = - 35 + 9 ⇔ <em>x = - 13</em>
x + 15 = 17 ⇔ x = 2 ⇔ <em>x = 3</em>
- 5x - 10 = 10 ⇔ 5x = - 20 ⇔ <em>x = - 4</em>
Now is your turn. You can do it!!!
Only in d. are the number related by multiplication (Multiplied by 3 each time to get the next number in the sequence).
3 x 3 =9
9 x 3 =27
27 x 3 = 81 etc.
Answer:
14x² + 7y - 22
Step-by-step explanation:
Combine like terms.
5x² - 6y - 22 + 13y + 9x²
5x² + 9x² = 14x²
-6y + 13y = 7y
Reorder the terms.
14x² + 7y - 22
Hope that helps.
Answer:
k = 10
Step-by-step explanation:
X progresses by 25, while y progresses by 250.
So divide 250 ÷ 15 and your answer is 10.
Slope is the change in y over the change in x:
Slope = (y2 - y1) / (x2-x1)
Replace the letters in the equation with the given information:
1/2 = (1 - -1) / (15 -r)
Cross multiply:
1 * (15-r) = 2 * (1- -1)
Simplify:
15 -r = 4
Subtract 15 from each side:
-r = -11
Because r is negative, you need to multiply both sides by -1 to make r positive:
r = 11
