When you use this formula slope = rise/run like rise over run than you find the slope. rise me y and run means x. So when the line slopes downwards to the right it became negative slope as x increases and when line sloped upward to the right the slope become positive as y decreases.
formula to find slope: slope = rise/run or y/x
That will equal 7 2/5 I hoed this helped :)
3s + 4j = 360
1s + 3j = 220
This one we can solve using substitution, in that
s + 3j = 220 implies s = 220 - 3j (subtract 3j from each side).
Now substitute into the first equation:
3(220 - 3j) + 4j = 360. Solve for jackets.
660 - 9j + 4j = 360 [Distributive property]
660 - 5j = 360 [Add -9j + 4j]
Subtract 360 from each side, and add 5j to each side.
660 - 360 - 5j + 5j = 360 - 360 + 5j
300 = 5j
Divide each side by 5.
$60 = price of a jacket.
Three of these plus a shirt runs $220.
3(60) = 180
180 + s = 220
180 - 180 + s = 220 - 180 [Subtract 180 from each side]
s = 40
Now we double check.
3(40) + 4 (60) = 120 + 240 = 360. This satisfies the first equation.
We could check the second one too, but I'm satisfied.
Answer:
12.5 miles per hour
Step-by-step explanation:
1,100 ft/min * (60 min)/(1 hr) * (1 mile)/(5280 ft) = 12.5 miles/hr
Hello!
Let's solve this equation for y first.
-10x+y=4
Add 10x to both side.
y=10x+4
Now, let's plug in our x-values to find y.
x: -2, -1, 0, 1, 2
y:-16,-6, 4,14,24
I hope this helps!
