Answer:
-3.75
Step-by-step explanation:
the opposite changes the sign from positive to negative, so the opposite of 3.75 would be -3.75
Answer:
1.6 = x axis || 2.5 = y axis
Step-by-step explanation:
each line is 0.5
Find the slope first using m=y2-y1/x2-x1
-4-4/0-4 =2
The y intercept is when x=0.
One of the given points is (0,-4)
The y intercept is y=-4
Answer:
3x^2-6x -3
Step-by-step explanation:
(2x^2-5x+1)+(x^2-x-4)
we sum all coefficient according to the exponent of the variable
2x^2-5x+1+x^2-x-4 = 3x^2-6x -3
Answer:
B
Step-by-step explanation:
First create the equation that has slope of -1 in the form of y=mx+b. Because the slope is -1, m=-1, so the equation is y=-x+b. Now we see that we are given the point (-3, 8) as an intersection point. Substitute x and y for -3 and 8 in our equation. With this information, our equation becomes 8=3+b. Solving, b=5. Our equation is now y=-x+5.
Simplifying all of the answer choices, we have
A. y=-x-5
B. y=-x+5
C. y=-x-5
D. and E. as what they already show
The only answer that matches is B.
