Identify the equation in slope-intercept form for the line containing the point (0,7) and perpendicular to y=−5/4x+11/4. HELP PL
777dan777 [17]

To write the equation of a line I need slope and y intercept (0,y)

I have y intercept (0,7)  of +7 as written in the equation

The equation y=-5/4x + 11/4 has a slope of -5/4

To get perpendicular slope is negated reciprocal

so take -5/4 and flip it -4/5 and change the sign (in this case negative to positive)  4/5

so the new equation is y=4/5x +7 (third one)

Who got the answer to this ? <br> (4x^2+6+7)-(-8x^2-2x+6)
Andru [333]

Answer:

12x^2+2x+7

Step-by-step explanation:

Distribute the Negative Sign:

=4x^2+6+7+−1(−8x^2−2x+6)

=4x^2+6+7+−1(−8x^2)+−1(−2x)+(−1)(6)

=4x^2+6+7+8x^2+2x+−6

Combine Like Terms:

=4x^2+6+7+8x^2+2x+−6

=(4x^2+8x^2)+(2x)+(6+7+−6)

=12x^2+2x+7
