Answer:
Measure of CD = 17 units
Step-by-step explanation:
Perimeter of a polygon = Sum of measures of all sides of the polygon
Perimeter of the given rectangle = 2(length + width)
= 2[(x + 3) + (2x - 1)]
= 2(3x + 2) units
Perimeter of triangle EFG = EF + FG + GE
= (x - 7) + (4x - 8) + (3x + 1)
= (8x - 14)
= 2(4x - 7) units
Since, perimeters of both the figures are equal,
2(3x + 2) = 2(4x - 7)
3x + 2 = 4x - 7
4x - 3x = 7 + 2
x = 9
Measure of CD = (2x - 1)
= 2(9) - 1
= 17 units
Answer:
29 times
Step-by-step explanation:
We can find this answer by dividing 87 by 3
87/3 = 29
We can prove this by multiplying 29 times 3 which gives us 87
Answer:
y = -x + 8
Step-by-step explanation:
The equation can be written as;
y = mx + b
where b is the y-intercept
From the diagram , b= 8
y = mx + 8
To get m, substitute (8,0 ) into the equation
0 = 8x + 8
x = -8/8
x = -1
So the full equation is;
y = -x + 8
Answer:
A
Step-by-step explanation:
We can see that Function A's y coordinate doubles every time. The function A = f(x) = 5(2)^x. It is an exponential growth function, and therefore y can never be 0. This means that A does not have an x-intercept.
Function B is a rational function. x cannot be 0, since that would result in an undefined number. This also means that B does not have an x-intercept.
