Answer:
y = -1/4x + 3
Step-by-step explanation:
Because you are finding the perpendicular slope, you need to find the negative reciprocal of the original line, which would be -1/4. You then use point slope form to find the y-intercept with the slope and given point:
y - 5 = -1/4(x + 8). That equals to y = -1/4x + 3.
So the equation of this line is y = -1/4x + 3.
Answer:
Larger number = 32
Step-by-step explanation:
Smaller number = x
Larger number = y
y - x = 8 -----------(I)
3y = 4x ---------------(II)
3y/4 = x
Plug in x = 3y/4 in equation (I)
y = 8*4
y = 32
Plug in y = 32 in equation (II)
3y = 4x
3*32 = 4x
4x = 3*32
x =
x = 3 *8
x = 24
Answer:
60
Step-by-step explanation:
60% * x = 45% * 80
Changing to decimal form
.60x = .45 *80
.60x =36
Divide each side by .60
.60x/.60 = 36/.60
x =60
Answer:
.
Step-by-step explanation:
Start by finding the slope of this line.
If a slanting line goes through and , where , the slope of this line would be:
.
The line in this question goes through and . Hence, the slope of this line would be:
.
If a slanting line with a slope of and goes through the point , the equation of this line in the point-slope form would be:
.
For the line in this question, the slope is . Take as the chosen point on this line. The point-slope form equation of this line would be:
.
Rewrite to obtain the equation of this line in the slope-intercept form:
.
