Answer:
Step-by-step explanation:
Rate of change= slope/gradient (Constant of proportionality, slope, unit rate)
By the Pythagorean Theorem, the longest side of a right triangle squared is equal to the sum of the squared sides...
h^2=x^2+y^2, where h=hypontenuse, and x and y are the side lengths...
87^2=w^2+63^2
w^2=87^2-63^2
w^2=3600
w=√3600
w=60 in
So the base of the frame is 60 inches wide.
Answer:
slope: 7
y intercept (0 , 0)
Step-by-step explanation:
y = 7x
equation of line: y = mx + b m: slope b: y intercept
slope = 7
y intercept: 0 (0 , 0)
Answer:
1. x=27
2. x=3
Step-by-step explanation:
<h3>the first one </h3>
let's solve your equation step-by-step.
x−7=20
Step 1: Add 7 to both sides.
x−7+7=20+7
<h3>the second one </h3>
Let's solve your equation step-by-step.
3x+6=12x−21
Step 1: Subtract 12x from both sides.
3x+6−12x=12x−21−12x
−9x+6=−21
Step 2: Subtract 6 from both sides.
−9x+6−6=−21−6
−9x=−27
Step 3: Divide both sides by -9.
−9x/−9=−27/−9
