A^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5
Answer: The number he needs, a, is 5
Answer:
The equation that relates the amount of yellow paint, y, and the amount of blue paint,b, in liters .
Step-by-step explanation:
Given that The Green Goober mixes 333 liters of yellow paint with 555 liters of blue paint to make 888 liters of special green paint for his costume.
So,
The amount of yellow paint: the amount of blue paint
If the amount of yellow paint is y and the amount of blue paint is b, then, from the above relation
Hence, the equation that relates the amount of yellow paint, y, and the amount of blue paint,b, in liters .
Answer:he needs no more cups of water
Step-by-step explanation:
Its simple, graph them.
For the first equation, go on the Y-Axis (the vertical one) and go to 4. Then from there go up 1, right 6.
For the second equation go on the Y-Axis (the vertical one) and plot a point at 1 (aka 0,1) Now you go up 1, right 3.
When you see an equation like y=2x+3, the 3 represents the point (0,3) as when the x is 0, y=3. Just plug the numbers in. And as for the "2x" 2 is the slope. Slope is always rise/run or up, then right. So if its 2 your slope is 2/1, rise 2, over 1. If it "-2x" is your slope then all you have to do is go down 2, right 1.
I hope this cleared up your confusion, brainliest/heart would help.
You plug in 4 for x
Which would be
(-4)^2-(-4)
-4×-4=16
16-(-4)
16+4=20
f(-4)=20
