yes it is correct

with parentheses you have to bring EVERYTHING INSIDE THE PARENTHESES to the given power but not if there are no parentheses

I know someone already answered this but they would be correct. This is how I think of it... if it does not have parentheses and it is a negative number and it has an exponent well then your answer will be negative but if you do have parentheses and your number is negative and it has an exponent well then your answer will be positive.

Yes, the triangle is right angled.

Step-by-step explanation:

Given lengths are;

11 yards, 60 yards and 61 yards

From pythagoras theorem;

The sum of square of shorter lengths is equal to square of larger side.

Here;

a = 11 , b = 60 , c = 61

a^2+b^2=c^2\\(11)^2+(60)^2=(61)^2\\121+3600=3721\\3721=3721

As it satisfies the condition of Pythagoras theorem, the triangle is right angled.

Yes, the triangle is right angled.

Standard form to slope intercept form <br> 6x+5y=50
cestrela7 [59]
To put it in slope intercept form, you want to solve for y.
5y = -6x + 50
y = -6/5x + 10

So, your slope is -6/5 (or -1.2) and your y-intercept is +10.

On a coordinate plane ,the segment with endpoints (10,40) and (70,120) is dilated by a factor of 4/5,with the origin as the cent
mestny [16]

The length of the dilated line segment is 80 units.

<h3>What is dilation?</h3>

Dilation is the increase or decrease in the size of a figure or object.

The segment with endpoints (10,40) and (70,120) is dilated by a factor of 4/5 to get (8, 32) and (56, 96).

The distance between points (8, 32) and (56, 96) is:

Distance = \sqrt{(96-32)^2+(56-8)^2} =80\ units

The length of the dilated line segment is 80 units.

From the figure below, the coordinates for point z are:<br> HELP PLS
Gelneren [198K]

Answer:

(2a, 0)

Step-by-step explanation:

the distance from (a,0) and z from the origin and to each other is both 3. It’s in the middle of two points, there’s an equal distance between w to y and y to z. I hope that makes sense, so, to get the x coordinate multiply a by 2.
