Answer:
the answer is A. -16
Step-by-step explanation:
3(-16)+3= -45
-45/5=
-9
5(-16)-1=-81
-81/9=
-9
-9=-9
m = money earned in one week
h = hours worked
x = times credit card was swiped
m = 14.45h + 8.50x
Given the next quadratic function:

to sketch its graph, first, we need to find its vertex. The x-coordinate of the vertex is found as follows:

where <em>a</em> and <em>b</em> are the first two coefficients of the quadratic function. Substituting with a = 2 and b = 3, we get:

The y-coordinate of the vertex is found by substituting the x-coordinate in the quadratic function, as follows:

The factorization indicates that the curve crosses the x-axis at the points (-2, 0) and (1/2, 0). We also know that the curve crosses the y-axis at (0,-2). Connecting these points and the vertex (-0.75, -3.125) with a U-shaped curve, we get:
Answer:
a) 42. b) 64. c) 39.
Step-by-step explanation:
a. 6 x 7 = 42
b. 8 x 8 = 64
c. 3 x 13 = 39
First you would have to find the third angle in the triangle which you would do by adding 63+61 and subtracting the resulting number from the total degrees in a triangle. From there, you would calculate x and y using the knowledge that angles on a line equal 180.
