(7 + 5 + 5 + 2 + 8 + 7) / 6 = 34/6 = 5.67

(34 + 2 + x) / 8 = 5.67 - 1
(36 + x) / 8 = 4.67
36 + x = 4.67 * 8
36 + x = 37.36
x = 37.36 - 36
x = 1.36

Please Help! The graph of y=f(x) is shown below. What are all of the real solutions of f(x)=0? (Picture of graph included)
qwelly [4]

Answer:

(7, 0), (-8, 0), (0, 0)

Step-by-step explanation:

y = f(x) = 0

the real solutions are the ones that cross the x-axis because when a point is on the x-axis, its y coordinate will be 0.

=> (7, 0), (-8, 0), (0, 0)

Rewrite the following fractions as division problems. a. 7⁄11 b. 5⁄2 c. 9⁄10 d. 7⁄15
larisa [96]
A. 7/11= 7 ÷ 11
B. 5/2= 5 ÷ 2
C. 9/10= 9 ÷ 10
D. 7/15= 7 ÷ 15

A fraction is just a division problem. 7/11 would be considered 7 ÷ 11 (or just 7/11) just do the same for the rest of the fractions.

Solve sin^2x+cos2x-1/4=0
sweet-ann [11.9K]
sin^{2}x + cos2x - \frac{1}{4} = 0
sin^{2}x + cos^{2}x - sin^{2}x = \frac{1}{4}
cos^{2}x = \frac{1}{4}
cos(x) = \pm \frac{1}{2}

x = \pm \frac{\pi}{3}
General solutions: x = \pi(n - \frac{1}{3}) and x = \pi(n + \frac{1}{3})
