Tell whether x and y show direct variation. x + y = 6​
Over [174]
<h3>Answer: Not direct variation</h3>

The reason why is because it can't be written in the form y = kx

If we solved the given equation for y, we get y = -x+6. It has a y intercept of 6, but it should be zero if we wanted a direct variation equation.

Kevin's bank offered him a 4.5% interest rate for his mortgage. If he purchases 3 points, what will be his new rate?
erma4kov [3.2K]

Answer:

The new rate would be  3.75%

Step-by-step explanation:

Purchasing a point simply implies negotiating for a lower rate of interest, which involves paying 1% of the loan in lieu of 1% interest reduction.

A point implies a reduction in interest rate by 0.25% while 3 points would reduce the interest rate by 0.75%(0.25%*3)

New interest rate=4.5%-0.75%=3.75%

The following triangle is equilaterial triangle. Solve for the unknown variable.
Iteru [2.4K]

Answer:

d

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent, then

2x = 6 ( divide both sides by 2 )

x = 3

and

3y = 6 ( divide both sides by 3 )

y = 2

Thus x = 3 and y = 2 → d

Use substitution 9x-3y=9 3x-y=3
zhannawk [14.2K]

Answer:

x=1

Step-by-step explanation:

3x-y=3

y=3-3x

9x-3y=9

9x-3(3-3x)=9

9x - 9 + 9x=9

9x + 9x=9 + 9

18x=18

x=18÷18

x=1
