Answer:
A
Step-by-step explanation:
the y intercept is -3
the slope is 3/4.
slope is defined as rise over run (up/down and then right/left)
Answer:
Step-by-step explanation:
One
The input is the top line. B is the output when multiplied by 4
B = 4A
Input A 12 15 47 34
Output B 48 60 188 136
Rule: 12 * 4 = 48; 15*4 = 60
Check the other two.
Two
B = A/2
Input A 44 56 18 26 20
Output B 22 28 9 13 10
Rule: 44/2 = 22; 56/2 = 28
Check the others.
The answer would be 5 i hope this helps!
Answer: 41 degrees
Step-by-step explanation:
so, we know that a triangle is 180 degrees. since we know that one angle is 80 degrees, we can subtract that from the equation. now, we are trying to find what X is so that we can find the angle. here is how i did it:
i rewrote it and removed the parentheses.
4x + 1 + 4x + 19 = 100
then, i collected like terms and calculated it.
8x + 20 = 100
then, i moved the constant to the right.
8x = 100 - 20
then, i simply calculated it.
8x = 10
solution: x = 10
so, we just insert X into the angle for A. that gets us 4(10) + 1 = angle A
40 + 1 = angle A, hence angle A = 41 degrees.
