Answer:Yes
Step-by-step explanation:You are multiplying the ratios by 4
Answer: B
Step-by-step explanation:
If you use slope-intercept form, you can see that B uses the equation y = 5x - 4, and you can also see that it is linear since it is proportional. The only coordinate plane that has a nonlinear line is D.
Answer:
1st Question
A. 85
2nd Question
B. 71
Step-by-step explanation:
1st Question
{90 + 94 + 96 + 90} = 370/4 = 92.5
{95 + 99} = 194/2 = 97
{87 + 75 + 82 + 85} = 329/4 = 82.25
{71} = 71/1 = 71
.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175 Rounded-up = 85
___________________________________________________
2nd Question
.10(95) +.20(80) +.50(67) +.20(60) = 71
The slope is 0 I’m pretty sure because it is a horizontal line, if it was a vertical line it would be undefined
3+2=4 4*2=8 hope that helps
