PLEASE HEPP IM STUCK

Mathematics

Ann [662]2 years ago

Answer:

m = -4

Step-by-step explanation:

We are given that a line intersects the points (-2, 9) and (3, -11).

We want to write the slope of this line.

The slope (m) can be found using the formula \frac{y_2-y_1}{x_2-x_1}, where (x_1, y_1) and (x_2, y_2) are points.

Even though we have everything we need to calculate the slope, let's label the values of the points to avoid any confusion & mistakes.

x_1=-2\\y_1=9\\x_2=3\\y_2=-11

Now substitute these values into the formula (remember that the formula has subtraction).

m= \frac{y_2-y_1}{x_2-x_1}

m=\frac{-11-9}{3--2}

Simplify.

m=\frac{-11-9}{3+2}

Subtract the values on top.

m=\frac{-20}{3+2}

Now add the values on the bottom together.

m=\frac{-20}{5}

Now divide -20 by 5.

<u>m = -4</u>

If the amount of air in a spherical balloon is 288 pi cu. in.,
vivado [14]
The balloon assumes the shape of a sphere with a formula of the volume equal to V = 4/3 pi r^3 where r is the radius of the balloon. In this case, we are given with volume of 288 pi in^3. We just substitute the given volume such that the resulting radius that answers the problem is 6 inches.

3a-5b:3a+5b=1:4 find the value of a and b
GarryVolchara [31]

Answer:

a = 5/6 , b = -3/10

Step-by-step explanation:

3a-5b:3a+5b=1:4

3a-5b / 3a +5b = 1/4

Cross multiply

3a -5b =4 ..........(1)            solve simultaneously

3a + 5b = 1 ..........(2)    using elimination method

-----------------------

Add equation 1 and 2

6a = 5

Divide both sides by 6

6a/6 = 5/6

a =5/6

Put value of a into equation 2

3a +5b = 1

3(5/6) + 5b = 1

5/2 + 5b = 1

5b = 1 -  5/2

5b = - 1½

5b = - 3/2

Divide both sides by 5

5b/ 5 = -3/2 ÷ 5

b = -3/2 × ¹/5

b = - 3/10

Therefore a = 5/6 , b = -3/10
