Answer:
F
Step-by-step explanation:
1(10) + 12= 22
2(10) + 12= 32
etc.....
Slide 14: you have to measure it
Slide 11: No they do not form a proportion because they are not related. You can do 20 push ups per minute, while your friend can do 19.
Slide 15: 4. Actual is 15 5. Actual is 35 6. Model is 4 7. Model is 2.5
Slide 13: 1. Proportional 2. Proportional 3. Not proportional 4. Proportional
Slide 12: m=77 a=10 g=16 w=160
Hope I’m not too late!
Let 11x + 15y + 23 = 0 be equation (1)
And 7x - 2y - 20 = 0 be equation (2)
Multiply equation (1) by 2:
22x + 30y + 46 = 0
Multiply equation (2) by 15:
105x - 30y - 300 = 0
Add equations (1) and (2):
22x + 105x + 30y - 30y + 46 - 300 = 0
127x - 254 = 0
127x = 254
x = 254/127
[x = 2]
Substitute x = 2 in equation (1) to find y:
11(2) + 15y + 23 = 0
22 + 15y + 23 = 0
15y + 45 = 0
15y = -45
y = -45/15
y = -3
Therefore, x = 2 and y = -3.
