Answer: -a+5
First you combine like terms
a-2a equals -a
After that you can’t combine anything else
So the equation simplified is -a+5

A ball is thrown with an initial speed of 17 mph in a direction that makes an angle of 22 degrees with the positive x-axis. Expr
Agata [3.3K]

Answer:

The speed of the ball in terms of i and j is (15.76 i, 6.37 j)

Step-by-step explanation:

Given;

velocity of the ball, v = 17 mph

angle of inclination, θ = 22⁰

The horizontal component of the velocity is calculated as;

V_x = Vcos\theta\\\\V_x = 17cos(22)\\\\V_x = 15.76 \ i

The vertical component of the velocity is calculated as;

V_y = Vsin\theta\\\\V_y = 17sin(22)\\\\V_y = 6.37 \ j

Therefore, the speed of the ball in terms of i and j is (15.76 i, 6.37 j)

The Cheer Squad is raising money to pay for their trip to the State Finals. They already have $1200 and they are selling really
Vlad [161]

Answer:

10c + 1200 ≥ 3000, c≥ 180

Step-by-step explanation:

We know that they need at least $3000; meaning, it may be $3000 or more. This leaves us with eliminating the bottom two choices.

We then look at the first two choices. If we were to subtract from 1200, we would not know the total income amount that has been gained. It would also eventually give us negative numbers. We cannot have a negative amount earned. Instead, we would use the 10c+1200 because this would allow us to visualize that it needs to be greater than or equal to 3000

Which equation can you use to solve for x​
svet-max [94.6K]

As for a specific equation, I could not say. However, I can tell you how to find x!

The first thing to remember is that a straight line has a 180 degree angle.

You see on the bottom side that we have a 146 degree angle. Now look at the top side. Look closely, and you will see that the two sides are actually identical!

Don't see it? Look at the line on top between x and 56, and imagine it is not there. You see that we actually have the same 146 degree angle, just flipped right side up!

However, this angle does not say 146, but makes an extra line between them with x and 56. This means that x + 56 equals 146!

So we can find x by subtracting 56, from 146, which is... 90!

Prove that the value of the expression: (125^2+25^2)(5^2–1) is divisible by 39
prisoha [69]

Answer:

(1252+252)(52−1)

=(1252+252)(52+−1)

=(1252)(52)+(1252)(−1)+(252)(52)+(252)(−1)

=390625−15625+15625−625

=390000

divide by 39 is

=10000
