What was Jada’s error?
alukav5142 [94]
The correct answer is: "Jada should have multiplied both sides of the equation by 108"

The goal of this equation is to isolate x, which is something that Jada failed to do. And the only way to isolate x is to multiply each side by 108, since it is the reciprocal of \frac{1}{108}

-7m²-10m+17<br> common factor
kicyunya [14]

Answer:

Greatest common factor of 17

So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!

Step-by-step explanation:

Add and subtract the second term to the expression and factor by grouping.

- (m - 1 )( 7m + 17 )

Write an equation of the line parallel to y=3x+5 and passing through the point (5,9) in point-slope form. Show all work.
Yuri [45]

Answer:

y - 9 = 3(x - 5)

Explanation:

y=3x+5

If you want the equation parallel, then the slope will be: 3

Point Slope Form: y - y_{1} = m( x - x_{1})

Since we have everything we need for this equation, we just need to fill in the blanks:  y - 9 = 3(x - 5)

Help 10 POINTS MATH IS NOT MY STRONG SUIT
Masja [62]

Answer:

infinite number of solutions

Step-by-step explanation:

Work with the second equation.  Subtract 8x from both sides.

- 4y + 8x - 8x = -8x - 12                   Collect like terms.

-4y = - 8x - 12                                   Divide by - 4

-4y/-4 = - 8x/-4 - 12/-4

y = 2x + 3

That is exactly the same line as the first given.  There is an infinite number of solutions.
