X - the number

x+\frac{1}{3}x+\frac{1}{8}x=70 \\
\frac{24}{24}x+\frac{8}{24}x+\frac{3}{24}x=70 \\
\frac{35}{24}x=70 \\
x=70 \times \frac{24}{35} \\
x=2 \times 24 \\
x=48

The number is 48.

Complete the table shown below. f(x) = 2x2 - 8x + 6 1 0 2 y 3 4. 6 X= y = Z ​
Serga [27]

Answer:

x = 6, y = -2, z = 0

Step-by-step explanation:

To find x, we have to plug 0 into f(x). Therefore, x = f(0) = 2 * 0² - 8 * 0 + 6 = 6. Similarly, to find y, we have to plug 2 into f(x) so y = f(2) = 2 * 2² - 8 * 2 + 6 = -2. Finally, z = f(3) = 2 * 3² - 8 * 3 + 6 = 0.

2y-4x=-12 what is the slope intercept
SpyIntel [72]
So you have yo turn it into the correct form first so you add 4x to both sides and come out with 2y=4x-12 them you divide each side by 2 because you have to have to by itself and you come out with y=2x-6 so the slope is 2x and the y intercept is -6

Can somebody help me solve this?
Nookie1986 [14]

Answer:

z = 3.2 units

Step-by-step explanation:

sin 76°/z = sin 51°/2.6

cross-multiply to get:

z·(sin 51°) = 2.6·(sin 76°)

z = 2.6·(sin 76°) ÷ (sin 51°)

z = 3.2
