Can someone give me a step by step explanation because my teacher doesn’t teach us anything? :(

Alex

Answer:

(7x^2 -1)(x - 2).

Step-by-step explanation:

7x^3 - 14x^2 - x + 2

We can factor this by grouping - that is factoring the first 2 terms and the last 2:

= 7x^2(x - 2) - 1(x - 2) <-- the x - 2 is common to both parts so we have:

(7x^2 -1)(x - 2).

A car uses 1 2/5 gallons of gasoline to travel 50 3/4 miles. How far can the car travel, in miles, on 1 gallon of gasoline?

Leya [2.2K]

Answer:

30 9/20

Step-by-step explanation:

(50 3/4)-((2/5) x (50 3/4)

=30.45

=30.45/1

=30.45/1 x 100/100

=3045/100

=3045÷5/100÷5

=30 9/20

30.45= 30 9/20

Hope this helps have a good day.

ANSWER

$y = 2x - 4$

EXPLANATION

To find the equation of BC, we must find the slope and use the point B(4,4) with the slope to find the equation.

We know the slope of BC is perpendicular to the slope of AB.

But the slope of AB
$= \frac{4 - 5}{4 - 2}$

$= - \frac{1}{2}$

The slope of BC is the negative reciprocal of the slope of AB, which is
$= - \frac{ 1 }{ - \frac{ 1}{2} }$
$= - 1 \times - \frac{2}{1} = 2$

The equation in slope intercept form is given by,

$y = mx + c$

This implies that,

$y = 2x + c$

The point B(4,4) lies on this line so it must satisfy its equation,

$4 = 2(4) + c$

$4 = 8 + c$

$c = 4 - 8 = - 4$

The required equation is,

$y = 2x - 4$

The correct answer is A
