Step-by-step explanation:

Step 1: Define

(5x + 3) - (2x - 6)

Step 2: Simplify

Distribute negative: 5x + 3 - 2x + 6
Combine like terms (x): 3x + 3 + 6
Combine like terms (Z): 3x + 9

Answer: 3 (x+3)

Explain:

Remove the parentheses - 5x+3 - 2x-6

Add like terms - 5x+-2x=3x and 3+6 = 9

Now we have 3x + 9

Factor the expression - 3 (x+3)

How much does 2.5 L of oil cost if 2,000 mL costs $5.00? Show work

kkurt [141]

Answer:

$6.25

Step-by-step explanation:

2000ml = 2 litres

2.5L - 2L = 500ml

So now we know that without the 500ml, it is 5 dollars.

Find out how much 500 ml cost.

2000ml = 5.00

1ml = 5.00 ÷ 2000 = 0.0025

500ml = 0.0025 x 500 = 1.25

2L + 500 ml = 2.5L (which 2.5L costs 6.25)

This table models a linear function. x −8 −4 4 8 y −3 0 6 9 Enter the coordinates of the y-intercept in the boxes.

adell [148]

Answer:

y-intercept is 3

Step-by-step explanation:

We are given table

x: -8 -4 4 8

y: -3 0 6 9

We can select any two points

$x_1=-8,y_1=-3$

$x_2=-4,y_2=0$

Firstly, we will find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{0+3}{-4+8}$

$m=\frac{3}{4}\quad$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

we can plug values

$y+3=\frac{3}{4}(x+8)$

now, we can solve for y

$y=\frac{3}{4}x+3$

For finding y-intercept , we can plug x=0

$y=\frac{3}{4}\times 0+3$

$y=0+3$

$y=3$

So,

y-intercept is 3

36x^2-21x-30 factor

miv72 [106K]

Easy...

to even begin to factor..you must factor out a 3, to simplify your answer.

3(12 $x^{2}$ -7x-10)

Now, you can factor.

$3(12 x^{2} -7x-10)$

So..to find the answer...

12*-10=-120x
and
you would use -7x

What multiplies to -120..but adds to -7?

-15*8=-120
and
-15+8=-7

To find the answer, plug in what you know..

3(3x+2)(4x-5)

Thus, your answer.
