It's 11 degrees.

Since you have to do 4 - -7, you can leave the seven, change the subtraction sign to an addition, and make -7 the opposite (7), the equation would be 4 + 7, making it 11 degrees.

What is the answer to this question ? Please answer !!
mylen [45]

\text{Let}\ k:y=m_1x+b_1\ \text{and}\ k:y=m_2x+b_2,\ \text{then}\\\\k\ \perp\ l\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\-------------------------\\\text{We have}\ 5x-y=-4.\ \text{Convert it to the slope-intercept form:}\\\\5x-y=-4\qquad\text{subtract 5x from both sides}\\\\-y=-5x-4\qquad\text{change the signs}\\\\y=5x+4\to m_1=5\to m_2=-\dfrac{1}{5}\\\\\text{Therefore we have}\ y=-\dfrac{1}{5}x+b.\\\\\text{The line passing through the point (-2, 2).}\\\text{Put the coordinates of the point to the equation:}

2=-\dfrac{1}{5}(-2)+b\\\\2=\dfrac{2}{5}+b\qquad\text{subtract}\ \dfrac{2}{5}\ \text{from both sides}\\\\1\dfrac{3}{5}=b\to b=\dfrac{8}{5}\\\\\text{Therefore we have the equation of a line in slope-intercept form:}\\\\y=-\dfrac{1}{5}x+\dfrac{8}{5}\\\\\text{Convert it to the standard form}\ Ax+By=C:\\\\y=-\dfrac{1}{5}x+\dfrac{8}{5}\qquad\text{multiply both sides by 5}\\\\5y=-x+8\qquad\text{add x to both sides}\\\\\boxed{x+5y=8}\to\boxed{[B]}

Solve for a: 3a - 5(a - 2) = 34<br><br>A: a=1<br>b: a=-12<br>c: a=-22<br>d: a=0 ​
nalin [4]

Answer:

b. a=-12

Step-by-step explanation:

3a-5a+10=34

multiply -5 times a and -2

-2a+10=34

-5a from 3a

-2a=24

subtract 10 from both sides

a=-12

-2a divided by both sides
