Answer:

y = 2.6

Step-by-step explanation:

in order to solve for y in the equation 4(2y-1) = 3y + 9

we fisrt open the bracket according to BODMAS rule

4(2y-1) = 3y + 9

8y - 4 = 3y + 9

the next strp is to collect the like terms

8y -4 -3y = 9

please note that when ever you are taking a positive number across the equall to sign it changes to negative (-) same thing applies to negative sign it changes to positve(+) respectively

8y-3y = 9 + 4

5y = 13

divide both ides by 5

5y/5 = 13/5

y = 2.6

Factored form of 2x^2+x-3 must show work
frozen [14]

Answer:

(2x+3)(x - 1)

Step-by-step explanation:

Since there is no common number to factor by we must approach this problem differently:

Step 1:

Multiply leading coefficient (2) by the constant term (-3)

2 x -3 = -6

Step two:

Find two numbers that multiply to -6 but add to the middle coefficient (1).

You should find these numbers to be 3 and -2

Step 3:

Replace 1x in the equation with your found numbers

2x^2 - 2x + 3x - 3

Step 4:

Take out the greatest common factor from the first two numbers, and the last two numbers.

For 2x^2 - 2x the greatest common factor would be 2x

For 3x - 3 the greatest common factor would be 3.

Step 5:

Factor out the found common factors

2x(x-1) + 3(x-1)

The values inside the bracket should be the same.

Step 6:

Factor out (x-1)

(x - 1)(2x + 3)

Therefore the factored form is (2x + 3)(x - 1)

A phone company offers two monthly plans. Plan A costs $11 plus an additional $0.11 for each minute of calls. Plan B costs $27 p
irina1246 [14]

Solution:

Let x represent a number of calling minutes. According to the problem, we want:

11\text{ + 0.11 x = }27\text{ + 0.07 x}

now, putting the similar terms together, we obtain:

0.11\text{ x - 0.07 x = 27 -11 }

this is equivalent to:

0.04x\text{ = 16}

now, solving for x, we get:

x\text{ = }\frac{16}{0.04}\text{ = 400}

then, the correct answer for the first question is:

400 minutes is the number of minutes the two plans cost the same

now, for the second question, we can replace the above value (400 minutes) into the following equation:

11\text{ + 0.11(400) = }55

so that, the correct answer for the second question is:

$55 is the cost when the two plans cost the same
