In the xy -plane, what is the y -intercept of the graph of the

1 answer:

6 0

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

 y = 2 (x + 3) (x - 4)

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

 y = 2 ( 3 ) ( -4 )

 y = 2 ( -12 ) = -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.

SOLUTION:

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.

1. If a = -1 , the value of3a + 1 is

erastovalidia [21]

Answer:

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

Therefore, -2 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:

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
