Answer:
3.6 and 8.4
Step-by-step explanation:
you put it into proportions
?/12= 30/100
you do 30 times 12
then divide it by 100
?/12 = 70/100
multiply 70 and 12
then divide it by 100
C. Karla says that to solve the equation you first subtract 15 and then divide by 10.
Karla is given the equation 10x + 15 = 20 to solve. She says the solution is 1/2
10x + 15 = 20
10x = 20 - 15 (subtract 5)
10x = 5 (divide by 10)
x = 5/10 = 1/2
Answer:
Figure P'Q'R'S' has been dilated by a scale factor = 1.5 to form image quadrilateral P"Q"R"S".
Step-by-step explanation:
From the graph attached,
Coordinates of point T' → (2, -2)
Coordinates of point T'' → (3, -3)
As it's clear form the picture, quadrilateral P'Q'R'S' has been dilated to form the image quadrilateral P"Q"R"S" by a scale factor = k
By the rule,
T'(x, y) → T"(kx, ky)
Therefore, T'(2, -2) → T"(2k, -2k)
T"(2k, -2k) → T"(3, -3)
By comparing x-coordinates,
2k = 3
k =
k = 1.5
Therefore, figure P'Q'R'S' has been dilated by a scale factor = 1.5 to form quadrilateral P"Q"R"S".
Answer:
13
Step-by-step explanation:
It is a parallelogram so the opposite angles are the same.
All angles sum to 360 degrees.
This means that the adjacent angles sum to 180 degrees.
4a + 11 + 9a = 180 = 13a + 11
13a = 169
a=13
The Y-intercept is found when X is equal to 0.
In the table, when X is 0, f(x) is 1.
On the graph, when X is 0 the line crosses at Y = 1.
This means that they are equal.
The answer would be equal to.
