Judging by the little marks on the sides, EF is the midsegment. midsegment is half of the base length
so 3x+5=80
3x=75
x=25
Answer:
the like terms are 2xy, -xy, and xy. In other words: 2, 4, & 6
Step-by-step explanation:
Objective: Solving Piecewise Functions
Analyze the info in the graph.
We know that if x=1, the graph will coincide at 5.
If x is greater than 1, the answer will be x squared it answer so any positve interger greater than 1 the answer is that squared.
If x is less than 1, the answer will be double that x.
Let check the answer choices.
A is wrong because x is less than 1 so the answer should be 2(-2)=-4 not 4.
C is Wrong, since 5 is greater than 1, it must be 25 so 5^2=25
D and B are both right, 2 is greater than 1 so 2 squared =4 and Whenever x=1, it will equal 5.
Answer:
The equation of the line is y=-x
Step-by-step explanation:
To find the equation for a line, we need to know 2 points.
One of the points is (0,0) because it goes through the origin. Another point is (5,-5). We can calculate the slope because we have 2 points using the formula.
m = (y2-y1)/(m2-m1)
m = (-5-0)/(5-0)
m = -5/5
m=-1
The slope is -1
We know the y intercept (where it crosses the y axis) is 0. Using the slope intercept form of a line
y = mx+b
y =-1x+ 0
y = -x
The equation of the line is y=-x
