Responder:

<u>3x² - 3x -3 </u>

Explicación paso a paso:

Dado

Área de una pared = 3x² - 5x + 14

Área de la otra pared = 2x - 17

El área total de las dos paredes es la suma de las áreas de ambas paredes como se muestra;

Área total = 3x² - 5x + 14 + 2x - 17

Área total = 3x² -5x + 2x + 14-17

Área total = 3x² - 3x -3

Por tanto, el área total de ambas paredes es <u>3x² - 3x -3 </u>

What is the slope of a line that is perpendicular to a line whose equation is 3y=−4x+2 ?
vova2212 [387]

we know that

if two lines are perpendicular, then the product of their slopes is equal to minus one

so

m1*m2=-1

Step 1

<u>Find the slope of the given line</u>

we have

3y=-4x+2

Solve for y

Divide by 3 both sides

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

y=-\frac{4}{3}x+ \frac{2}{3}

the slope of the given line is m1=-\frac{4}{3}

Step 2

<u>Find the slope  of a line that is perpendicular to the given line</u>

we have

m1=-\frac{4}{3}

m1*m2=-1

m2=-1/m1

substitute the value of m1

m2=-1/(-4/3)=\frac{3}{4}

therefore

<u>the answer is</u>

the slope is \frac{3}{4}

Graph the system of equations on your graph paper to answer the question. {y=−3x+9y=−x−5 What is the solution for the system of
marysya [2.9K]

y=−3x+9 slope of this equation is -3 and y-intercept is 9

Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9

y=−x−5 slope of this equation is -1 and y intercept is -5

Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5

The intersection point of these two lines gives you the solution.

The coordinates of point of intersection (7,-12)
