What is the equation of the line that passes through the point (-1,7) and is parallel to the line y= -2x-1

Mathematics

Nuetrik [128]3 years ago
3 0

if we look at the equation y = -2x - 1, is already in slope-intercept form, therefore, \bf y=\stackrel{slope}{-2}x-1 has a slope of -2.


now, parallel lines have exactly equal slopes, therefore a parallel to that one above, will have also a slope of -2, so we're really looking for a line whose slope is -2 and runs through -1, 7.


\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{7})\qquad \qquad \qquad slope =  m\implies -2\\\\\\\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-7=-2[x-(-1)]\\\\\\y-7=-2(x+1)\implies y-7=-2x-2\implies y=-2x+5

Simplify the expression 10-4x(6+5-1) divided by 8+7
Eddi Din [679]
Simple,

writing out the problem...

\frac{10-4x(6+5-1)}{15}

Simplify it...

-4x(6+5-1)

-4x(11-1)

-4x(10)

-40x

Making it look like...

\frac{10-40x}{15}

Cancel out the common factors...

Thus making the answer:

- \frac{2(4x-1)}{3}.

T<br> ✓<br> Х<br> Find the sum of (x2 – 7x + 5) and (-3x2 - x + 10)<br> [
Zanzabum

Answer:

-2x² - 8x + 15 = 0

Step-by-step explanation:

Given the following algebraic expression;

x² – 7x + 5

-3x² - x + 10

To add the equation together;

x² – 7x + 5 + (-3x² - x + 10) = 0

x² – 7x + 5 - 3x² - x + 10 = 0

Collecting like terms, we have;

(x² - 3x²) - (7x + x) + (5 + 10) = 0

-2x² - 8x + 15 = 0
