Answer: 37) 170
Step-by-step explanation:
85 - (-85) = 85 + 85 = 170
Answer:
y=-5/3x+13.
Step-by-step explanation:
As a line that is perpendicular to anoher line has a slope that is the negative reciprocal of the line's original slope, we know that the slope of our new line is -5/3. As it passes point (12, -7), we can use the point slope formula which is y-y1=m(x-x1). So plug in, y+7=-5/3(x-12) and that gives us y+7=-5/3x+20 which gives our final answer of y=-5/3x+13.
Answer:
Domain and Range are both all real numbers.
Step-by-step explanation:
For the function y=1.3x + 12 there are no restrictions on the function. Therefore all values are used for the x inputs and y outputs. So the domain is all real numbers and y is all real numbers.
Answer:
<em>y = 1/3x - 2</em>
Step-by-step explanation:
Line y = 1/3x + 5 has slope 1/3, so the line we are looking for also has slope 1/3.
y = 1/3x + b
We know a point, so we plug in the values of x and y, and we solve for b.
y = 1/3x + b
-1 = (1/3)(3) + b
-1 = 1 + b
b = -2
Now that we know b, the equation is:
y = 1/3x - 2
