Answer:
4
Step-by-step explanation:
3^2=9
-2 times 3 = -6
9-6+1=4
Answer:
75
Step-by-step explanation:
Homework mean x 10%: (80+100+90)/3 x 0.1 = 90 x 0.1 = 9
Quiz mean x 25%: (84+90+72)/3 x 0.25 = 20.5
Test mean x 45%: (64+72)/2 x 0.45 = 30.6
Sum of means/percentage of grade: 9 + 20.5 + 30.6 = 60.1/.8 = 75.125
The answer is b because of the thing right there’s
Answer:
C (Y = -5/8x - 10)
Step-by-step explanation:
first find the slope (y₂ - y₁) ÷ (x₂ - x₁)
(5 - (-20)) ÷ (-24 - 16)
-5/8 = slope (m)
now that we know the slope is -5/8 we can rule out A and B
now to find the y intercept just substitute a point in for x and y
5 = (-5/8)(-24) + b
multiply
5 = 15 + b
subtract 15 from both sides tp isolate b
-10 = b
