Answer:
f(-7) = -6
f(10) = 9
Step-by-step explanation:
Because -7 is less than 0 you can use the top equation -7 + 1 to get 6
Because 10 is greater than 0 you can use the bottom equation 10 - 1 to get 9
Answer:
<h2>
4x+4</h2>
Basic fact:
<em>all sides of a square are equal</em>
Step-by-step explanation:
1 side is x+1 so all sides are x+1
there are 4 sides so times everything by 4
4(x+1) which is 4x+4
<u>Step-by-step explanation:</u>
Co-ordinates = (4,8) & (-9,5)
Slope (m) = (y² - y¹) / (x² - x¹)
(m) = (5 - 8) / (-9 - 4)
(m) = -3 / -13
(m) = 3 / 13
Equation => y = mx + c
Answer:
x = 66
y = 68
Step-by-step explanation:
y is the same as the angle that is 68 degrees. Then, because the total of 46, x, and y should = 180, you solve for 180 by plugging in the y value.
46 + x + 68 = 180
114 + x = 180
x = 66
Answer:
1.7 feet
Step-by-step explanation:
R is the midpoint of QS, so RS = 4 feet.
Using sine:
sin 25° = RT / 4
RT = 4 sin 25°
RT ≈ 1.7
