<h3>
Answer: 100 degrees</h3>
===============================================================
Explanation:
The two angles that involve x are alternate interior angles.
Due to the parallel lines, the alternate interior angles are equal.
We'll use this to solve for x
-7x-18 = -9x-46
-7x+9x = -46+18
2x = -28
x = -28/2
x = -14
Let's check the answer by evaluating each expression as shown below
- -7x-18 = -7*(-14)-18 = 80
- -9x-46 = -9*(-14)-46 = 80
Both angles are 80 degrees each, so it confirms we have the correct x value.
-----------------------
We have one last step. We found the -9x-46 angle to be 80 degrees. Angle 4 is adjacent to this and supplementary.
So we subtract from 180 to get the answer
180-80 = 100
F(x)= 4 lx+6l
f(x)= 4 (x+6)
f(x) = 4x + 24.
Hopes this helps you out.
If c= the cost and n=number of pounds then
c=0.89n
would be the correct answer because the cost is determined by the amount of pounds of apples Sam buys.
Here,
y=mx+c
the slope of the line 6x+4y= -16 is -20.
if the two lines are perpendicular, the slope of 1st line * slope of second line=-1
the slope of the 2nd line is -1/2
y-y1=m(x-x1)
y-13=-1/2(x- -18)
when you solve, you get the equation of the line as 2y+x=50
In basic geometry, if two geometry objects intersect at right angles (90 degrees or π / 2 radians), they are vertical.
If two lines intersect at right angles, the line is perpendicular to another line. Explicitly (1) if two lines intersect, the first line is perpendicular to the second line. (2) At the intersection, the straight line angle on one side of the first line is cut by the second line into two congruent angles. Verticality can be shown as symmetric. That is, if the first line is perpendicular to the second line, then the second line is also perpendicular to the first line. Therefore, two straight lines can be said to be perpendicular (to each other) without specifying the order.
