Question 3 - 1 Point

Mathematics
1 answer:
exis [7]2 years ago
3 0

Answer:

m∠A=42

Step-by-step explanation:

Since they are complementary they must add up to 90°.

(2x+30)+(6x+12)=90

We can just remove parenthesis since you can't really do anything with them.

2x+30+6x+12=90

Combine like terms.

8x<u>+42</u>=90

Do inverse to find the value of x.

<u>8x</u>=48

x=6

Now since we are looking for the m∠A and not x we need to replace the x with the value of x in the ∠A equation.

(<u>2(6)</u>+30)

(<u>12+30</u>)

m∠A=42

An object in a simulation accelerates
notsponge [240]

Observe the graph below. This graph represents the scenario.

The question is ill formated, the complete question is

In a simulation, a moving object accelerates from rest to 4 meters per second in 2 seconds. For the following three seconds, it increases linearly until it reaches a speed of 10 meters per second. Following three seconds at that speed (acceleration = 0), the item progressively decelerates until it comes to rest two seconds later. Draw the graph of this scenario for 10 seconds?

I'll describe how the graph may show.

It will move diagonally upward from time 0 to 2 seconds until it reaches the y axis at a speed of 4 m/s.

Then, from 2 to 5, the position will move up diagonally until it reaches the y axis at a speed of 10 m/s.

The next 5 to 8 seconds will be horizontal.

After that, it will descend diagonally.

Observe the graph below. This graph represents the scenario.

All computers are on sale for 10% off the original price. If x is the original price of the computer, then the function that rep
prohojiy [21]
So the original price is "x".

the discounted price by 10% is P(x) = 0.9x.

the price minus a $150 coupon is C(x) = x - 150.

so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!! wait a minute!! you have a $150 coupon, and you can use that for the purchase, so you're really only getting out of  your pocket 0.9x - 150, namely the discounted by 10% and then the saving from the coupon.

C(   P(x)   ) = P(x) - 150

C(   P(x)   ) = 0.9x - 150

Does this graph show a function? Explain how you know.
Natasha2012 [34]

Answer: D. No; the graph fails the vertical line test.

The vertical line test is a tool used to determine if we have a function. If we can draw a single straight vertical line through more than one point on the red curve, then the graph is said to have failed the vertical line test. Consequently, this leads to the relation not being a function.

For this circle graph, we can draw a vertical line through more than one point, which is why we don't have a function here.

Put another way, there are inputs (x) that produce more than one output (y), so that's why we don't have a function.

What is the slope and y-intercept of 2y-10=-4x
geniusboy [140]

Answer:

y=-2x+5

Slope: -2

y int. 5

Step-by-step explanation:

Convert to slope intercept form

2y-10=-4x

Add 10 to both sides

2y-10+10=-4x+10

Simplify

Divide both sides by 2

\bold{\frac{2y}{2}=-\frac{4x}{2}+\frac{10}{2}}

Simplify

y=-2x+5

Slope: -2

y intercept: 5

Show steps to solve for y=2x-2y​
levacccp [35]

Answer:y=2/3x

Step-by-step explanation:

y=2x-2y

combine like terms

y+2y=2x

y=1

so 1y+2y=3y

3y=2x

divide 3 on both sides 3y =2x
