Answer: 91
Step-by-step explanation: I assume you had a typo and mean what did Ana need on the 5th quiz since you only listed 4 quiz scores.
(74 + 92 + 83 + 100 + x)/5 = 88
(349 + x)/5 = 88
((349 +x)/5) x 5 = 88 x 5
349 + x = 440
x = 440-349
x = 91
<span><span>Molly: 105 x 05/02 = 42</span>
Kim: 105-42</span> = 63
<span> Laura: 385-105 = 280
280 x 100/385</span><span> = 72%
Donc Laura obtient 72</span>%
Answer: y = 1/8x+1
y=mx+b is slope intercept form
given m = 1/8 and a point we can find b by plugging in what we have
1=1/8(8)+b
1=1b
b=1
So then we know m = 1/8 and b = 1
y=1/8x+1 is the answer
Answer:
Linear equations that go in a straight line.
They are linear so they don’t curve like parabolas.
Step-by-step explanation:
See this picture. It will definitely help you!
Y = 7x^2-3
x=7y^2-3
