Answer:
9/3=3
Step-by-step explanation:
the formula is y2(7) minus y1(-2)
divided by x2(-4) minus x1(-7)
Answer:
B. -7
Step-by-step explanation:
f(x) = 4x + 5
To find the value of f(-3), replace all the x's in f(x) with -3.
f(x) = 4x + 5
f(-3) = 4(-3) + 5
f(-3) = -12 + 5
f(-3) = -7.
This makes your answer B, -7.
Answer: 67°
Step-by-step explanation:
Complementary angle refers to the angle that when added together will be equal to 90°.
Let the measurement of the angle's complement be x.
Therefore, the angles are x and 2x + 21. Since it's a complementary angle, therefore,
x + 2x + 21 = 90
3x + 21 = 90
3x = 90 - 21
3x = 69
x = 69°/3
x = 23°
Therefore, the angle will be:
= 2x + 21
= 2(23°) + 21°
= 46° + 21°
= 67°
The angle is 67°.
