Answer:
the answer should be A) 12
Step-by-step explanation:
54 ÷ 3^2 × 2
54 ÷ (3 × 3) × 2
54 ÷ 9 × 2
6 × 2
12
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the points (4, -4) and (k, -1) and the slope m = 34.
Substitute:
![\dfrac{-1-(-4)}{k-4}=34\\\\\dfrac{3}{k-4}=\dfrac{34}{1}\qquad|\text{cross multiply}\\\\34(k-4)=3\qquad|\text{use distributive property}\\\\34k-136=3\qquad|+136\\\\34k=139\qquad|:34\\\\k=\dfrac{139}{34}](https://tex.z-dn.net/?f=%5Cdfrac%7B-1-%28-4%29%7D%7Bk-4%7D%3D34%5C%5C%5C%5C%5Cdfrac%7B3%7D%7Bk-4%7D%3D%5Cdfrac%7B34%7D%7B1%7D%5Cqquad%7C%5Ctext%7Bcross%20multiply%7D%5C%5C%5C%5C34%28k-4%29%3D3%5Cqquad%7C%5Ctext%7Buse%20distributive%20property%7D%5C%5C%5C%5C34k-136%3D3%5Cqquad%7C%2B136%5C%5C%5C%5C34k%3D139%5Cqquad%7C%3A34%5C%5C%5C%5Ck%3D%5Cdfrac%7B139%7D%7B34%7D)
Answer:
- (139/2)
Step-by-step explanation:
18 1/2 -2^3•(4 1/3 + 6 4/6)
= 37/2 - 8 .( 13/3 + 40/6)
= 37/2 - 8 x 11
=37/2 - 88
= - (139/2)
