It would be b because a^2+b^2=c^2 so in this case 5^2+8^2=c^2
Answer:
y = |1/4x|
Step-by-step explanation:
The slope is 1/4
Answer:
y = 100x + 400
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 400) and (x₂, y₂ ) = (1, 500) ← 2 points from the table
m = 
= 100
note the line crosses the y- axis at (0, 400) ⇒ c = 400
y = 100x + 400 ← equation of line
Since these are parabolas with y being squared, the standard form of such a parabola with vertex at (h, k) is
<span>x = a(y - k)^2 + h </span>
<span>There are no steps. Just look at what is inside the parentheses and compare it to (y - k) with k = -3. </span>
<span>Then look at what is added and compare it to h = -1. </span>
<span>For instance, A has (y + 1) in parentheses. So k = -1. And it has -3 added, so h = -3. That would be a vertex at (-3, -1).</span>
Answer:
x= 5/4
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain x.
