5x-2y=-4
5x-2(0)=-4
-5x=-4
x=-4/5, so the x-intercept I'd (0,-4/5). Hope it help!

5x - 2y = -4

To find the x-intercept, you make y = 0

So, our equation now looks like this :

5x - 2(0) = -4

Simplify.

5x - 0 = -4

5x = -4

Divide both sides by 5.

x = -4/5

So, our x-intercept is -4/5

* Remember, ALWAYS make y = 0 when solving for the x-intercept*

~Hope I helped!~

Can somebody please help with this? ​
Digiron [165]

Answer:

x=8°

y= 96°

z= 96°

Step-by-step explanation:

Solve for z first. The whole circle is 360° so if you only count half the angles it will add up to 180°.

Solve for z:

48+36+z=180°

84+z+180°

z=96°

Now that you have z you can solve for x by using only the bottom half of the circle.

z+36+6x=180° *remember z=96

96+36+6x=180

132+6x=180

6x=48

x=8°

Now you can solve for y by either plugging x into an equation or by knowing that opposite angles are equal.

y=96°

Against the wind a commercial airline in South America flew 630 miles in 3.5 hours. With a tailwind the return trip took 3 hours
Salsk061 [2.6K]

Answer:

The speed of plane is 195\ mph, and speed wind is 15\ mph.

Step-by-step explanation:

Given against the wind the airline flew 630 miles in 3.5 hours.

including the tailwind the return trip took 3 hours.

Let speed of plane is x.

Also, speed of the wind is y.

Now, we will find speed on each case.

Speed against the wind is  \frac{630}{3.5}=180\ mph

Speed with the wind is \frac{630}{3}=210\ mph

Now, we will write the equation

x+y=210\\x-y=180

Add these equation we get,

2x=390\\x=\frac{390}{2}\\x=195\ mph

Now, plug this value in x+y=210 to get speed of wind

195+y=210\\y=210-195\\y=15\ mph

So, the speed of plane in still air is 195\ mph, and speed of the wind is 15\ mph.
