Answer:

-1(7x+12)(x+1)

Step-by-step explanation:

1) Find out which two integer numbers whose product result in -84 and whose sum is -5?

-7x² +5x +12= 0

Product ( )*( )= -84

And Sum ( )+( )= 5

12 * -7 = -84 and 12 +(-7) = 5

2) We now can rewrite the above trinomial as

-7x²+12x-7x-12=0

3) Group them, highlight the MCD and rewrite it as a product.

x(7x+12) -1(7x-12)=0  Maximum Common Divider in evidence

x(7x+12) -1(7x-12)=0 Common Factor in bold multiplied by -1

-1(7x-12)(x+1) The Second term was divided by -1

-1(7x+12)(x+1)=0

4) Test it, to check your work

-1(7x+12)(x+1)

-1[7x²-5x-12]

-7x²+5x+12

12=10(s+4)+50 what is the written problem to this can you help me with the answer
muminat

Answer:

s = -7.8

Step-by-step explanation:

from the question 12=10(s+4)+50

<u>first step</u>

open the bracket and evaluate for the value of s

12=10(s+4)+50

12 = 10s + 40 + 50

12 = 10s + 90

collect or combine the like terms

12-90 = 10s

-78 = 10s

divide both side by 10

-78/10 = 10s/10

-7.8 = s

therefor s = -7.8

The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB in slope-intercept form that contains poi
bazaltina [42]

Answer:

The equation would be y = 2x - 8

Step-by-step explanation:

The equation of the line would have a slope of 2, since parallel lines have the same slope. We can use that and the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y + 2 = 2(x - 3)

y + 2 = 2x - 6

y = 2x - 8

Miamor wanted to make note cards by cutting pieces of paper in half.
Minchanka [31]

Answer: 14 pieces

Step-by-step explanation:

Let the number of pieces of paper she had at first be x.

Before starting she got seven more pieces to use. This can be written as:

= x + 7

When she was done she had 28 half pieces of paper. This can then be written as:

x + 7 = (28 × 1/2)

x + 7 = 14

x = 14 - 7

x = 7

Since x = 7, she started with:

= x + 7

= 7 + 7

= 14 pieces
