Answer:

x = -50

Step-by-step explanation:

Let's solve your equation step-by-step.

−2x+4=104

Step 1: Subtract 4 from both sides.

−2x+4−4=104−4

−2x=100

Step 2: Divide both sides by -2.

−2x/-2 100/-2

=-50

2. Write your own equation in slope intercept form. Identify the slope, m, and y-intercept, b.

liberstina [14]

Slope intercept form
y = mx + b:

10 = 7x + 3

y = 10
slope (m) = 7
b = 3

standard form:
Ax + By + C:

7x + 10y + 3

A = 7
B = 10
C = 3

hope this helps

a group of astronauts launched a model rocket from a platform. Its flight path is modeled by h= -4t^2+24t+13 where h is the heig

Eddi Din [679]

Answer:

6.5 seconds

Step-by-step explanation:

Keep in mind that when $h=0$ , this is the same height for both when the model rocket takes off and lands, so when the rocket lands, time is positive. Thus:

$h=-4t^2+24t+13\\\\0=-4t^2+24t+13\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-24\pm\sqrt{24^2-4(-4)(13)}}{2(-4)}\\ \\t=\frac{-24\pm\sqrt{576+208}}{-8}\\\\t=\frac{-24\pm\sqrt{576+208}}{-8}\\\\t=\frac{-24\pm\sqrt{784}}{-8}\\\\t=\frac{-24\pm28}{-8}\\\\t=\frac{-24-28}{-8}\\ \\t=\frac{-52}{-8}\\ \\t=\frac{52}{8}\\\\t=6.5$

So, the amount of seconds that the model rocket stayed above the ground since it left the platform is 6.5 seconds

Paul baked 208 brown loaves. if the ratio of white loaves to brown loaves is 3:2, how many loaves did he bake in total

navik [9.2K]

Answer:

520 loaves

Step-by-step explanation:

First, let's find how many white loaves he baked.

Let's make a proportion.

white loaves/brown loaves= white loaves/brown loaves

He baked 3 white loaves for every 2 brown loaves. He baked x white loaves for 208 brown loaves.

3/2=x/208

Now, we have to solve for x. To do this, we have to get x by itself. x is being divided by 208. To reverse this, multiply both sides by 208

208*3/2=x/208*208

208*3/2=x

312=x

He baked 312 white loaves.

Now, we have to find the total number of loaves he baked.

To do this, add the brown loaves and the white loaves.

brown loaves+white loaves

He baked 208 brown loaves and 312 white loaves

208+312

520

He baked 520 loaves in total

A ball is thrown horizontally with a speed of 10 m/s, from the edge of the top of the building of height 19.6m, and later strike

kodGreya [7K]

1) You need to solve t - $19.6=.5(9.8)t^2$
2) Then solve f $vf^2=2(9.8)(19.6)$
3) As it's constant it is still 10m/s
4) You need to use the time from part 1 times 10m/s
5) Use Pythagorean theorem with 10m/s and vf

I am pretty sure it will help you.
