Answer:

The bottom graph on the right, check the image below:

Explanation:

Substitute the x value with 1,

f(1)=1(1+2)=3

f(2)=2(2+2)=8

f(-1)=-1(-1+2)=-1

f(-2)=-2(-2+2)=0

Yuki888 [10]

Answer:

Step-by-step explanation:

$5(y - 3.8) = 4.7(y - 4)$

Distribute 5 through the parentheses

$5y - 19 = 4.7(y - 4)$

Distribute 4.7 through the parentheses

$5y - 19 = 4.7y - 18.8$

Move ' 4.7 y ' to L.H.S and change it's sign

$5y - 4.7y - 19 = - 18.8$

Move constant to R.H.S and change it's sign

$5y - 4.7y = - 18.8 + 19$

Collect like terms

$0.3y = - 18.8 + 19$

Calculate

$0.3y = 0.2$

Divide both sides of the equation by 0.3

$\frac{0.3y}{0.3} = \frac{0.2}{0.3}$

Calculate

$y = 0.67$

Hope this helps...

Problem Set

insens350 [35]

5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.

3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.

Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is

(3 L) / (8 L) = 0.375 = 37.5%

Which expression is equivalent to m^2-13m-30?

sergiy2304 [10]

Answer: First option

Step-by-step explanation:

You have the quadratic equation given in the problem:

$m^2-13m-30$

To find an equivalent expression you cacn factorize. Find two numbers whose sum is -13 and whose product is -30.

These numbers would be -15 and 2.

Therfore, you obtain the following equivalent expression:

$(m-15)(m+2)$

If you don't want to apply the method above, you can use the quadratic formula:

$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$

Where:

$a=1\\b=-13\\c=-30$

When you susbstitute values you obtain that:

$x=15\\x=-2$

Then you can rewrite the equation as $(m-15)(m+2)$
