Answer:
B. (0,0)
Step-by-step explanation:
The y-intercept of the equation f(x) = 1/2x lies on the y-axis.
This means we need to set x = 0 and solve for y
1/2(0) = 0
Therefore, (0,0) is the y-intercept of this equation.
What we know:
Area=l x w
vertices at (-4,0),(-3,1), (0,-2),(-1,-3)
pythagorean formula=a²+b²=h²
What we need to find:
Area
Finding length:
Length of rectangle is from point (-4,0) to (-1,-3), found it by plotting the points on graph paper. Went down 3 units and right 3 units to go from one point to the other, these are the a and b in the pythagorean formula.
a²+b²=h²
(3)²=(3)²=h²
9+9=h²
18=h²
√18=√h²
√18=h
Finding width:
Width of rectangle is from point (-4,0) to (-3,1), found it by plotting the points on graph paper. Went up 1 unit and right 1 unit to go from one point to the other, these are the a and b in the pythagorean formula.
a²+b²=h²
(1)²+(1)²=h²
1+1=h²
2=h²
√2=√h²
√2=h
Now we can find area,
Area= l x w
= √18 x√2
=√36=6
Area=6
Remember that when we square root a number we get two solutions, one negative and one positive but since length, width and area are positive we only use positive solutions.
I think it’s B. You wouldn’t have to multiply since it’s only adding or subtracting, and you don’t add exponents when you’re adding monomials.
Answer:
x=2
Step-by-step explanation:
have a nice day
I believe this is it.
x is Coleman's test grade.
x/2 +27 = 67 Now solve for x
-27 -27
x/2=40
*2 *2
x=80
Coleman's Test Score was 80.
