Answer:
2nd choice OC.y=-2x+3
Step-by-step explanation:
The equation for the slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. With these two numbers both given to us, we can just plug them in and get y=-2x+3.
Hope this helps you
Answer:
5x +3y = -14
Step-by-step explanation:
The equation of the given line is in standard form. This makes it easy to write the equation for a perpendicular line.
__
<h3>form</h3>
The perpendicular line will have a slope that is the negative reciprocal of the slope of the given line. This can be made to happen by ...
- swapping the coefficients of x- and y
- negating one of the coefficients.
So, the line perpendicular to 3x -5y = 2 will have an equation of the form ...
5x +3y = c . . . . . for some constant c
<h3>constant</h3>
The constant will be what is needed to make the line go through the given point. That is, for (x, y) = (-1, -3), the equation is satisfied.
5(-1) +3(-3) = c = -5 -9 = -14 . . . . . substitute values for x and y
<h3>equation</h3>
Then the equation for the perpendicular line through (-1, -3) is ...
5x +3y = -14
Answer:
80
Step-by-step explanation:
3x -1 = 11
3x = 11 + 1
3x = 12
x = 4
I take it by, x2 + x, you mean 2x + x, since x = 4, then
2x + x = 2(4) + (4) = 8 + 4 =12
