1) To solve for x, is to let x on the left side and the other terms and variables on the right side.
bx -10=f <em>Add 10 to both sides</em>
bx = f+10 Divide by b on both sides
So that's the way we solve for x.
b) For this one we multiply the whole expression by 2 and then isolate z on the left side, and the rest on the right side.
z = 2h +2b
Answer: y-3=4(x+1) in point-slope form and y=4x+7 in slope intercept form
Step-by-step explanation:
You can find the point-slope form by plugging the numbers into the following: y-y₁=m(x-x₁).
You will end up with y-(3)=(4)(x-(-1)) which when simplified equals y-3=4(x+1).
To find slope intercept form you know need to isolate y and simplify.
Adding 3 to both sides results in y=4(x+1)+3.
If you then distribute you get y=4x+4+3 which simplifies to y=4x+7.

Step-by-step explanation:
Answer:
x = 192
Step-by-step explanation:
The three right triangles in the figure are all similar, so their sides are proportional.
<h3>Proportion</h3>
The length marked x is the long side of the smallest triangle, and the short side of the middle-size triangle. The long side of the middle-size triangle is ...
400 -144 = 256
We now have enough information to write the proportion ...
long side/short side = x/144 = 256/x
Multiplying by 144x gives ...
x² = (144)(256)
x = √(144×256) = 12×16 = 192
The length x is 192 units.
