Answer:
Step-by-step Turn 7 into a fraction
3/5 ÷ 7/1
Use the recipricle and multiply
3/5 x 1/7
Multiply across
3/35
And that's it! :)
(13x^2 - 10x + 12) - (9x^2 + 20x - 50)
13x^2 - 10x + 12 - 9x^2 - 20x + 50
13x^2 - 9x^2 = <em>4x^2</em>
- 10x - 20x = <em>-30x</em>
12 + 50 = <em>62</em>
4x^2 - 30x + 62
Answer:
A. 78
Step-by-step explanation:
2a+24= 180
-24 -24
2a= 156
divide each side by 2
a= 78
Answer:
Graph A.
Step-by-step explanation:
When x is equal to 0, why has to be equal to 2. The slope also has to be 3. To find this out, we do y2-y1/x2-x1. For A, the slope is -7--4/-3--2. This is equal to -3/-1. This is equal to 3. Because y=2 when x=0. option A is correct. For option D, when x=0, y=32. Therefore, this option is not correct. For option B, when x=0, y=2 so this could be correct. Plug it into y2-y1/x2-x1. This is equal to -1-0/-1-2. This is equal to -1/-3. 1/3 is not equal 3 so this option is not correct either. When x=0, y=32 for option C. Therefore, this option is not correct. Therefore, the answer is option A.
