Answer:
C
Step-by-step explanation:
The first one (0,7) tells you that when x isn't there, the amount of money is 7.
That means that the y intercept is 7.
When x = 1 the total is 15
Money saved = ax + 7
15 = a*1 + 7 Subtract 7
15-7 = a + 7-7
a = 8
The equation is f(x) = 8x + 7
Answer:
The scale factor of the sides of the Octagon is 2:5
Step-by-step explanation:
Both these octagons can be considered as the combination of 8 similar triangles joined edge to edge.
We know this property of similar triangles, that the ratio of area of similar triangles is proportion to the square of the ratio of sides of the similar triangle.

From the above property, we plug in the values


Therefore, the ratio of the sides of the Octagon are 2:5.
Parallel lines are two lines that are not crossing each other for instance \\ that is a parole line
Answer:
B
Step-by-step explanation:
The slope of the line that passes through the given points is (4-7)/(-3-1) = 3/4.
Since parallel lines have equivalent slopes, the answer is B.
