How do you solve this? <br> Look at attached file please...I'm really confused!
il63 [147K]

Answer:

X=18, Y=6

Step by Step Explanation:

This is a little long winded.. Let's solve for Y first.

First looking at the problem, you can note a few things. First of all, there is an Isosceles triangle, and there is an equilateral triangle. Where they connect, there is a 90° angle.

Now, all equilateral triangles have the same angle measurement. 60°. Now, if you look where the right angle is, it is showing a 60° angle, a total of 90°, and an unknown area. So simply subtract. 90-60=30. Divide that by 5, and you have your answer of 6.

Now let's solve X. X is very simple. On an isosceles triangle, the two top sides are the same length. And one of the top sides is the same size as the equilateral triangle. And on equilateral triangles, all sides are the same.

So the 11 transfers over to the X side. So let's make a small equation. 11=X-7. To make it even, let's add 7 to both sides. 11+7=X+7-7. Simplify to get 18=X, which is your answer.

Here’s a graph of a linear function. Write the equation that describes that function. Express it in slope-intercept form.
Ipatiy [6.2K]

Answer:

y=4x-1

Step-by-step explanation:

Slope-intercept form is written in y=mx+b

  *m=slope

  *b=y-intercept

From what I see,

the line hits the points (0,-1) and (1,3)

Slope is the rise (change in the y-coordinate) of the line divided by the run (change in the x-coordinate).

4÷1=4

Slope=4

y=4x+b now

The y-intercept is the value of y when the line meets the y-axis

It seems to meet at (0,-1)

So we end up with...

y=4x-1 as our equation

DaniilM [7]

Answer:

y=\frac{306}{7} is the answer.

In decimal y = 43.71

Step-by-step explanation:

Given:

y varies directly with x .

Also x = 7 when y = 18

To Find:

y = ? when x = 17

Solution:

y varies directly with x .

i.e. y is directly proportional to x

∴ y = k\times x

Where

k = constant of proportionality {Remain Same}

First we will find constant of proportionality k,

∴ When x = 7 and y = 18 we have

∴ 18 = k\times 7\\\\k=\frac{18}{7}

Now when x= 17 and k=\frac{18}{7} we have

∴ y = k\times x

∴ y=\frac{18}{7}\times 17\\\\y=\frac{306}{7}\\\\ y=43.71
