Answer:
b
Step-by-step explanation:
to determine which point is a solution, substitute the x-coordinate of the point into the equation and if the value is equal to the y-coordinate of the point then it is a solution.
(a) (- 1, 3)
y = (- 2 × - 1) + 4 = 2 + 4 = 6 ≠ 3 ⇒(-1, 3) is not a solution
(b) (- 2, 8)
y = (- 2 × - 2) + 4 = 4 + 4 = 8 ⇒ (- 2, 8) is a solution
(c) (0, 1)
y = 0 + 4 = 4 ≠ 1 ⇒ (0, 1) is not a solution
(d) (4, 2)
y = (2 × 4) + 4 = 8 + 4 = 12 ≠ 2 ⇒ (4, 2) is not a solution
Answer:
Step-by The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.-step explanation:
Answer:
The correct answer is x =9
Step-by-step explanation:
It is given that, the polygons are similar.
Then the ratio of corresponding sides are equal.
<u>To find the ratio of corresponding sides</u>
corresponding sides are
16 and 12 ratio = 12/16 = 3/4
32 and 24 ratio = 24/32 = 3/4
x - 1 and 6
y + 1 and 21
Therefore we can write 6/(x-1) = 3/4
<u>To find the value of x</u>
6/(x-1) = 3/4
24 = 3(x-1)
24 = 3x - 3
3x = 27
x = 27/3
x = 9
Therefore the value of x = 9
