I don't think the correct y-intercept is offered as one of the choices.

                                         <u>  y = 2 (x + 3) (x - 4)</u>

Where the graph crosses
the y-axis, x=0 :                  y = 2 (0 + 3) (0 - 4)

                                           y = 2 ( 3 )  ( -4 )

                                           y = 2 ( -12 )  =  <em>-24

On Julie's trip to the mountains she traveled 192 miles using 6 gallons of gas. On the return trip she traveled 235 miles on 8 g
Tamiku [17]

Julie travelled with 30.5 miler per gallon.

<u>SOLUTION: </u>

Given, On Julie's trip to the mountains she traveled 192 miles using 6 gallons of gas.  

On the return trip she traveled 235 miles on 8 gallons of gas.  

We have to find how many miles per gallon did Julie get on the way there?

We know that,

\text { number of miles per gallon }=\frac{\text { total distance travelled }}{\text { total number of gallons }}

Substituting the values we get,

=\frac{192+235}{8+6}=\frac{427}{14}=30.5 \text { miles per gallon }

Hence, Julie travelled with 30.5 miler per gallon on the way there on mountains.

erastovalidia [21]

Answer:

f(a) = 3a + 1 \\ Now,\: a =  - 1 \\ f( - 1) = 3( - 1) + 1 \\ f( - 1) =  - 3 + 1 \\ \boxed{ f( - 1) =  - 2}

  • Therefore, <em><u>-2</u></em> is the right answer.

A angles of an equilateral triangle are congruent. If x represents the measure of the third angle of the triangle, what is x?
Tatiana [17]

Answer:

D

Step-by-step explanation:

Since x is the measure of the third angle and all 3 angles are congruent then

All 3 angles have a measure of x

The sum of the 3 angles in a triangle = 180°, this

x + x + x = 180 ← is the required equation

3x = 180 ( divide both sides by 3 )

x = 60
