CAN SOMEONE FIND "x" FOR ME PLZ :/

Answers

Answer:

9°

Explanation:

So, since the arrow is pointing to a RIGHT angle, you have to know the right angle's degree is 90° so set up an equation.

11x - 9 = 90

Now you solve it. Here's a step by step:

11x - 9 = 90

Add nine to nine and ninety. Since the nine in this equation is negative, it'll cancel it out. Now here's what you have left to solve:

11x = 99

Divide -11 from 11 and 99.

x = 9

If you feel like you're wrong, fill it in!

11(9) - 9 = 90

11 x 9 = 99

99 - 9 = 90

There you go!

Is y=-3.5x-10 proportional

Answers

Answer: =3.5x Slope:

3.5

y-intercept:

0

Step-by-step explanation:

y=-3.5x-10 is an inverse proportional.

Given that, the given equation is y= -3.5x-10.

What is a proportional relationship?

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Put x=0, 1, 2, 3, and 4 in the given equation.

When x=0

y=-10

When x=1

y=-3.5(1)-10

=-3.5-10

=-13.5

When x=2

y=-3.5(2)-10

=-7-10

=-17

When x=3

y=-3.5(3)-10

=-10.5-10

=-20.5

Here, x increases and y decreases, it is inverse proportionality

Therefore, y=-3.5x-10 is an inverse proportional.

Answer:

1. y = 4x - 4

2. y = x + 2

3. y = -2x - 4

4. y = -x + 2

Step-by-step explanation:

Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.

Find the value of a.

Answers

Answer: 14

Step-by-step explanation: The perimeter is all of the side added together. When finding the perimeter of a rectangle the opposing sides have the same value. So the equation would be 2(12) + 2(a) = 52. 12 x 2 is 24. 52- 24 is 28 and youre left with 28 = 2(a). You divide each side by 2 and get 14 = a

A model is made of an Airbus A300 aeroplane.
The length of the model is 36 cm.
The length of the real aeroplane is 54 m.

Answers

Answer:

Since the Airbus A300 model airplane was made to scale, measuring 36 centimeters, while the real airplane measures 54 meters, to determine the scale ratio between both planes, the following calculation must be performed:

36cm = 0.36m

0.36 = 1

54 = X

54 x 1 / 0.36 = X

150 = X

Therefore, the scale ratio between the model and the real plane is 150:1.
