So all you do is the exponents first the add multiply and divide until you get your answer. C
Answer:
x = 22°
Step-by-step explanation:
The angles of a triangle add to 180°, so:
69 + (3x - 4) + (3x - 17) = 180
(3x - 4) + (3x - 17) = 111
6x - 21 = 111
6x = 132
x = 22
False, since if there are two perpendicular lines with gradients m1 and m2, then m1*m2 = -1.
Taking this example -5/2 multiplied by 5/2 is equal to -25/4, which is not equal to -1.
To find the actual gradient of the perpendicular line you would have to divide -1 by -5/2, which gives you 2/5.
Y = mx + b
y is the total cost
The slope m is the rate: that's $8 per hour
x is the number of hours
b is the initial value: that's $16
y = 8x + 16
The problem states that the cost was $48.
Substitute that for y and solve for x.
48 = 8x + 16
32 = 8x
x = 4 hours
