what is the slope help pls?

Answers

Answer:

y=7x-6

Step-by-step explanation:

You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say

y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.

Can someone help please

Answers

Answer:

14.5 units

Step-by-step explanation:

we need to find the length of the rectangle. To do that, we must find the hypotenuse of the right triangle below the rectangle.

Finding the hypotenuse of a right triangle uses the Pythagorean theorem, or a² + b² = c²

let a be 9 and b be 7.

9² + 7² = c²

81 + 49 = c²

130 = c²

√130 = c

c = approx. 11.4

Now, we know the length of the rectangle.

Once a rectangle is cut diagonally, it forms 2 equal right triangles. We will use the same process to find the hypotenuse of the second right triangle.

9² + 11.4² = c²

81 + 130 = c²

81 + 130 = approx. 211

c² = 211

√211 = c

c = approx. 14.5

gjj h 7/4 to the third power Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

A flower garden is circular. The diameter of the garden is 20 feet. Which is the closest to the total area of the garden?

Answers

Answer:

40

Step-by-step explanation:

The total area of the garden is  31.75 sq meters

The first step is to calculate the radius if the circle

The diameter of the garden is 20 feet

2π × radius= 20

2π × 3.14= 20

6.28π= 20

π= 20/6.28

π= 3.18

The area of the flower garden can be calculated as follows

= π × radius²

= 3.14 × 3.18²

= 3.14 × 10.1124

= 31.75 sq meters

Hence the total area of the garden is 31.75 sq meters
