Answer:
y= 1/2x -7
Step-by-step explanation:
Find the y-intercept. It is where the line crosses "y" which is -7
Next find the rise and the run for "x"
Rise - 1
Run - 2
Then put them in slope intercept form
y=1/2x -7
Answer:
a = 14
Step-by-step explanation:
<u>Step 1: Write out your problem</u>
f (a) = 5a + 14 | f (a) = 0
<u>Step 2: Solve</u>
f (a) = 5 (0) + 14 , Input a.
f (a) = 0 + 14 , 5 x 0 = 0
(a) = 14 , 0 + 14
a = 14
Answer:
Rewrite so y is on the left side of the inequality.
−83y>43
Multiply each term by −38 and simplify.
Inequality Form:
y<−1/2
Interval Notation:
(−∞,−1/2)
Step-by-step explanation:
Answer:
27.5
Step-by-step explanation:
y = kx
55 = 120k
k = 55/120
y = 55/120 x 60
y = 55/2
y = 27.5
We know that
<span>A large pump can drain an 80,000 gallon pool------------> in 3 hours
X gallons---------------------------------------------------------> in 2 hour
X=2*80000/3----------> 53333.33 gallons in 2 hour
therefore
</span><span>the smaller pump in two hours drain an [80000-53333.33]=26666.67 gallons
</span><span>
if the </span>smaller pump drain 26666.67 gallons-----------------> in 2 hours
<span> 80000 gallons------------------------------------------------> X
X=80000*2/26666.67------> 6 hours
the answer is
</span><span>the smaller pump to drain the pool by itself would take 6 hours</span><span>
</span><span>
</span>
