Answer: What is the question????
Answer:
23 degrees
Step-by-step explanation:
90 + 67 = 157
180 - 157 = 23
there are always 180 degrees in triangles
D i think because it’s talking about the angling
-47 - 15y =-17.....Equation A
-x+ 5y=-13..........Equation B
Solve B for y.
-x + 5y = -13
5y = x - 13
y = (x - 13)/5
Plug y into A.
-47 -15y = -17
-47 -15(x - 13)/5 = -17
-47 -3(x - 13) = -17
-47 -3x + 39 = -17
-3x - 8 = -17
-3x = -17 + 8
-3x = -9
x = -9/-3
x = 3
Now that we know x is 3, plug 3 for x into EITHER Equation A or B (your choice) to find y.
I will let you do that.
Answer:
The answer is below
Step-by-step explanation:
A linear function is a function in the form y = mx + b, where y and x are variables, b is the y intercept (value of y at x = 0) and m is the slope (rate of change).
Let x represent the year and y represent the amount of rainfall in inches. The linear function can be gotten by selecting any two pair of points from the table in the form (x, y).
Let us use the points (2004, 62.33) and (2007, 60.74). The equation is gotten using:
![y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-62.33=\frac{60.74-62.33}{2007-2004}(x-2004) \\\\y-62.33=-0.53(x-2004)\\\\y-62.33=-0.53x+1062.12\\\\y=-0.53x+1124.45](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-x_1%29%5C%5C%5C%5Cy-62.33%3D%5Cfrac%7B60.74-62.33%7D%7B2007-2004%7D%28x-2004%29%20%20%5C%5C%5C%5Cy-62.33%3D-0.53%28x-2004%29%5C%5C%5C%5Cy-62.33%3D-0.53x%2B1062.12%5C%5C%5C%5Cy%3D-0.53x%2B1124.45)
