Answer:
Darnell can read 1,715 words in 7 minutes
Step by step Explanation:
1. I need to find out how many words he reads in 1 minute. Divide 735 by 3, my answer is 245
245
______
3)735
6 bring down the 3 to make 13
-_____
1 3
12 bring down the 5 to make 15
-______
1 5
15
___________
0
2. multiply 735 by 2 cause he reads 735 words in 3 minutes and we are tryna find out how many words he reads in 7 minutes. 3×2=6, so 735+735 (735×2) equals 1470
3. Add 245, for that extra minute that we missed. my answer is 1,715 words in 7 minutes
Answer:
y = (7/8)x + 7
Step-by-step explanation:
"7 over 8 x" is incorrect; you meant "(7/8)x" (which is not the same as "7 over 8 x." Thus, your line is y = (7/8)x - 7. The slope of a parallel line is the same, or (7/8). Given that the line passes thru (8,0), we have enuf info with which to calculate the y-intercept. Write out: y = mx + b. Immediately replace m with (7/8), y with 0 and x with 8, obtaining: 0 = (7/8)(8) + b. Then b = 7, and the equation of this new, parallel, line is y = (7/8)x + 7.
Vertex: (1,-6)
Axis of symmetry: x=1
