Answer:
( -9, -6)
Step-by-step explanation:
The red dot is the original (6, 9)
The blue dot is when it is rotated 270 degrees clockwise (-9, -6).
The slope of a line is the ratio of the change in y to the change in x. The slope of the given line is 1/2 = -6/-12. That is, when y changes by -6 to go from 6 to zero, x will change by -12 to go from 0 to -12.
The x-intercept is (-12, 0).
Those are just repeating equivalent decimals
Let x = total sales of baked goods remember 20% = .20 as a decimal
so the equation would be .20x = $600
divide both sides by .20
.20x/.20 = $600/.20
x = $3000 the total sales of baked goods
CHECK: 20% times $3000 = .20 times $3000 = $600
To solve the system if equations substitute the given values and simplify:
4x+2y=7
y=5x
To start off we are given what h equals already so we do not have to solve for it. This means we can just plug in its values into the first equation.
4x+2(5x)=7
Solve for x
4x+10x=7
14x=7
x=7/14
x=1/2
Now that we have an x value substitute back into the second equation to find the y value and be able to create a coordinate point.
y=5x
y=5(1/2)
y=5/2
y=2.5
So your answer would be
(1/2,5/2) or (0.5,2.5)
I hope this helps!
