Answer:
y=4
Step-by-step explanation:
First, we need to find the slope of the line (m)
the equation is (y2-y1)/(x2-x1)
let's label the points
x1=-2
y1=4
x2=2
y2=4
susbtitute into the equation
m=(4-4)/(2--2)
m=0/4
m=0
the slope is 0.
now let's use point slope form: y-y1=m(x-x1)
once again let's subsitute into the equation
y-4=0(x+2)
do distributive property
y-4=0
add 4 to both sides
y=4
the equation is y=4
hope this helps!
Should be all real numbers
Answer:
35 times
Step-by-step explanation:
60x + 480 = 2580
60x = 2100
x = 35
Answer:
k = -3/4
Step-by-step explanation:
The lines will be parallel if their slopes are equal. To find the slope of each line, write its equation in slope-intercept form (y = mx + b). In other words, solve each equation for y and look at the coefficient of x.
2x + 3y = 4k
3y = -2x + 4k
y = (-2/3)x + 4k/3
The slope of the first line is -2/3.
x - 2ky = 7
-2ky = -x + 7
y = [1/(2k)]x - 7/(2k)
The slope of the second line is 1/(2k).
If the slopes are equal, then
1/(2k) = -2/3
Multiply by 2k.
1 = (-2/3)(2k) = (-4/3)k
1 = (-4/3)k
k = -3/4
I’m going to say b.66 because 3.14•10.5•2=65.94
I got 10.5 by dividing 21 by 2 because I guessed it was the diameter
