Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.
Thus, lets form an equation:
90 = 5x + 19 + 4x - 1
72 = 9x
x = 9
Thus, the measure of angle B is 64°.
A graph which represents the linear function y = -2x is: graph B.
<h3>What is a graph?</h3>
In Mathematics, a graph can be defined as a type of chart that is typically used for the graphical representation of data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis respectively.
Generally speaking, the graph of any proportional relationship is characterized by a straight line with the data points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) either increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.
In this context, we can reasonably infer and logically deduce that the relationship between x-values and y-values in the graph of y = -2x is proportional as it passes through the origin (0, 0).

Answer:
43.3 cupcakes
Step-by-step explanation:
If shamans has 3&1/3 cups of flour to make cupcakes. If she needs 1/13 cup of flour to make one cupcake how many full cupcakes can she make
From the above question
1/ 13 cup = 1 cup cake
3 1/3 cups = x
Cross Multiply
1 /13 × X = 3 1/3 × 1
x = 10/3 ÷ 1 /13
x = 10/3 × 13/1
x = 130/3
x = 43.333333333 cupcakes
Answer: y = -2x + 7
Step-by-step explanation:
Slope intercept form is the same as solving for y in the equation .
So solve for y and it will be in slope intercept form.
12 - y = 2x + 5 Subtract 12 from both sides
-12 -12
-y = 2x -7 Now divide both sides by -1
y = -2x + 7
