Answer:

x=8.5

Step-by-step explanation:

To solve this equation, we want to find out what x is. To do this, we need to get x by itself.

Perform the opposite of what is being done to the equation. Remember to perform everything to both sides.

4(x-5)=14

4 is being multiplied by x-5. The opposite of multiplication is division. Divide both sides by 4.

4(x-5)/4=14/4

x-5=14/4

x-5=3.5

5 is being subtracted from x. The opposite of subtraction is addition. Add 5 to both sides.

x-5+5=3.5+5

x=3.5+5

x=8.5

Let's check our solution. Plug 8.5 in for x in the original equation.

4(x-5)=14

4(8.5-5)=14

4(3.5)=14

14=14

Both sides of the equation are the same, so we know our solution, x=8.5 is correct.

Find f(-2) for the function f(x) = 3r2 - 2x +7. 0-13 O-1 O 1 O 23

viva [34]

Step-by-step explanation:

f(x) = 3x² - 2x + 7

f(-2) = 3(-2)² -2(-2) + 7

= 3(4) + 4 + 7

= 23

Consider the surface z = x 2+4y 2+1. Suppose you are walking on this surface directly above a curve C in the xy-plane, where the

Bess [88]

With $x(t)=\cos t$ and $y(t)=\sin t$ , we have

$z(t)=x(t)^2+4y(t)^2+1$

$z(t)=\cos^2t+4\sin^2t+1$

$z(t)=3\sin^2t+2$

Then $z(t)$ has critical points where

$\dfrac{\mathrm dz}{\mathrm dt}=6\sin t\cos t=3\sin2t=0$

$\implies\sin2t=0\implies2t=n\pi\implies t=\dfrac{n\pi}2$

where $n$ is any integer.

$z(t)$ is increasing wherever $\sin2t>0$ , which happens for

$\dfrac{2n\pi}2$

$\boxed{n\pi$

Sophie [7]

Answer:

Step-by-step explanation:

First, divide 120 by two and get 60. Now do 120-60 to get 60. Set up proportion

60/x = x/60.

Cross multiply

x^2 = 3600

and now find the square root of 3600
