2 answer
Let x be weight of the baby
142=78+69-2x
142=147-2x
147-142 =2x
5=2x
2.5 = x
Answer:
15°
Step-by-step explanation:
7x + 12 + 63 = 180
7x + 75 = 180
7x = 180 - 75
7x = 105
x = 15
Answer:
y=1/5x+2
Step-by-step explanation:
In perpendicular lines the slopes are negative reciprocals so the slope of other line is 1/5x
And they intersect at (15,5) to find the y intercept(b)
y=1/5x+b
5=(1/5)(15)+b
5=3+b
b=2

Answer:
Step-by-step explanation:
#1 Synthetic method
- 2x³ + x² - 2x - 4 ÷ x + 1 = 2x² - x - 1 rem 3
--------------------------------------
x + 1 | 2x³ + x² - 2x + 4
---------------------------------
-1 | 2 1 -2 4
<u>| - 2 1 1 </u>
2 - 1 - 1 3
#2 Long division
- 3x³ - 5x² - 26x - 8 ÷ 3x + 1 = x² - 2x - 8
--------------------------------------
3x³ - 5x² - 26x - 8 <u>| 3x + 1</u> = x² - 2x - 8
<u>3x³ + x²</u>
-6x² - 26x
<u>-6x² - 2x</u>
- 24x - 8
<u>- 24x - 8</u>
