Answer:
y = -3x
Step-by-step explanation:
Slope-intercept form:
Slope formula:
Given points: (-2, 6), (2, -6)
(2, -6) = (x1, y1)
(-2, 6) = (x2, y2)
To write the equation in y = mx + b form, we need to know the slope(m) and the y-intercept(b). To find the slope, input the two given points into the slope formula:
Simplify:
6 - (-6) = 6 + 6 = 12
-2 - 2 = -4
The slope of the equation is -3. To find b, we can input the value of the slope and one point (in this example I'll use (2, -6) into the equation:
-6 = -3(2) + b
-6 = -6 + b
0 = b
The y-intercept is 0. Now that we know the slope and y-intercept, we can write the equation:
y = mx + b
y = -3x + 0
y = -3x
The equation written in slope-intercept form is y = -3x.
Answer:
f(x) = -1
Step-by-step explanation:
2/x when x = -2
2/-2 = -1
Answer:
C) x = 1
Step-by-step explanation:
By adding the like terms you get
-12x + 10 = -10x + 8
then you add 12x to both sides and subtract 8 to both sides and get
2 = 2x
which then you would divide 2 by 2 and get 1
Peter bought 8 maple donuts
If there are 25 fewer maple than chocolate, then we know there are at least 25 chocolate donuts. if we subtract those 25 chocolate from the total of 41, we have 16 left. with the 25 chocolate donuts taken out, the number of maple and chocolate donuts in the remaining 16 are the same, meaning there are 8 of each. Since the 25 we subtracted earlier were all the chocolate, there were 33 chocolate and 8 maple. Therefore, Peter bought 8 maple donuts.
Answer:
1 13/20
Step-by-step explanation:
3/4+9/10 = 15/20+18/20=33/20
33/20 as a mixed number is 1 13/20 which is in lowest terms.
