Answer:

y=2x-8

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept value.

It says the slope is 2, so we know that y = 2x+b. To find b, plug in a point given.  We are given (9,10), so plug that into the equation, where y = 10 and x = 9.  10=2(9)+b, solve for b.

b equals -8, so the answer is y=2x-8.

Answer:

y= 2x - 8

Answer:

B= [tex]\frac{2A}{H}[/tex]

Step-by-step explanation:

If you noticed, A= [tex]\frac{1}{2}[/tex]BH is the formula for finding the area for a triangle. Your goal is to get B by it's self. Your first step will be to clear of the fraction first, so you will multiply both sides by 2.   2(A)=2([tex]\frac{1}{2}[/tex]BH).    On the left, you have 2×A= On the right side, you have     2([tex]\frac{1}{2}[/tex]BH),     but since you have a number in the equation, you will only use 2×[tex]\frac{1}{2}[/tex]. To solve  2×[tex]\frac{1}{2}[/tex], you will cnacel out both 2's and you have 1. 1×BH will still equal BH, so you are now left will B×H.

(Your new equation looks like this by the way).    2A=BH

Since you need to get B by its self, the way to clear the H away from the B is by dividing.  You will now divide the B and H aswell as 2A and H. (It will look like this) [tex]\frac{2A}{H} = \frac{BxH}{H}[/tex] . (Again when you have the same number or letter, you cross it out. When you divide, you won't change anything on the left side, and all you have to do on the right id to cross out the H next to the B and cross out the H on the bottom of the equation). You should be left with [tex]\frac{2A}{H}[/tex] = B. Now you can turn it around for your final answer. B= [tex]\frac{2A}{H}[/tex].

It takes 42 minutes for 6 people to paint 7 walls

Solution:

It takes 54 minutes for 4 people to paint 6 walls

To find: Minutes required for 6 people to paint 7 walls

If [tex]M_1[/tex] men can do [tex]W_1[/tex] work in [tex]D_1[/tex] days working [tex]H_1[/tex] hours per day and [tex]M_2[/tex] men can do [tex]W_2[/tex] work in [tex]D_2[/tex] days working [tex]H_2[/tex] hours per day, then

[tex]\frac{M_1D_1H_1}{W_1} = \frac{M_2D_2H_2}{W_2}[/tex]

M = Number of men

D = Number of days

H = Number of hours per day

W = Amount of work

Here in this sum,

54 minutes for 4 people to paint 6 walls

[tex]H_1 = 54 minutes ; M_1 = 4 people ; W_1 = 6 walls[/tex]

Minutes required for 6 people to paint 7 walls

[tex]H_2 = ? ; M_2 = 6 people ; W_2 = 7 walls[/tex]

Substituting the values in formula, we get

[tex]\frac{54 \times 4}{6} = \frac{H_2 \times 6}{7}\\\\9 \times 4 = \frac{H_2 \times 6}{7}\\\\H_2 = \frac{36 \times 7}{6}\\\\H_2 = 42[/tex]

Thus it takes 42 minutes for 6 people to paint 7 walls

There is a graph

Answer:

4 feet

Step-by-step explanation:

From the question, we are given;

We are required to find the radius of the cylinder fish tank;

Volume = pi × r² × h

Rearranging the formula;

r² = V ÷ pi × h

Therefore;

r² = 320 pi ÷ (pi × 20 ft)

   = 16

Thus;

r = √16

  = 4 ft

Therefore, the radius of the fish tank is 4 feet.

slope of the given straight line in graph is -2

Step-by-step explanation:

Explanation:-

in given graph we have to choose points are A(0,3) on y-axis and B(1.5 , 0) on x- axis

let m be the slope of a line

by using slope formula is

[tex]m= \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

m = [tex]\frac{0-3}{1.5-0}[/tex]

m= -2

another points we have choose

in given graph we have to choose points are A(0,3) on y-axis and B(2.5 , -2)

slope of a line :-

let m be the slope of a line

by using slope formula is

[tex]m= \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

[tex]m = \frac{-2-3}{2.5-0}[/tex]

m= -2

where ever you will take point the slope of given straight line is

m = -2

30 kg of mocha coffee bean and 20 kg of java coffee bean should be used to make 50 kg of mocha java blend that will sell for $ 18 per kg

Solution:

Let "x" be the kilogram of mocha coffee beans

Let "y" be the kilogram of java coffee beans

Cost of 1 kg of mocha coffee bean = $ 20

Cost of 1 kg of java coffee bean = $ 15

Kilograms of each kind of coffee bean should he use to make 50 kg of the mocha-java blend

Cost of 1 kg of mocha java blend = $ 18

From given information,

Mocha coffee beans and java coffee beans are mixed to get 50 kg of blend

Therefore,

[tex]x + y = 50 ------------ eqn 1[/tex]

Abdul wants to make a mocha-java blend that will sell for $18/kg

Therefore, we frame a equation as:

(kilogram of mocha coffee beans) x (Cost of 1 kg of mocha coffee bean) + (kilogram of java coffee beans) x (Cost of 1 kg of java coffee bean) = Cost of 1 kg of mocha java blend x 50 kg

Thus we get,

[tex]x \times 20 + y \times 15 = 18 \times 50\\\\20x+15y = 900 ------------ eqn 2[/tex]

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 50 - y -------- eqn 3

Substitute eqn 3 in eqn 2

20(50 - y) + 15y = 900

1000 - 20y + 15y = 900

5y = 100

Substitute y = 20 in eqn 3

x = 50 - 20

Thus 30 kg of mocha coffee bean and 20 kg of java coffee bean should be used to make 50 kg of mocha java blend that will sell for $ 18 per kg

We need to set and solve a system of equations, with the variables representing the weights of mocha and java coffee in the blend. Solving the system yields the number of kilograms needed.

To solve your problem, Abdul, we will use the concept of weighted averages. We'll need two equations. Let's denote the weight of the mocha coffee in the mix by x kg and the weight of java coffee by y kg. From the problem's requirements, we get these two equations:

Now, the goal is to solve this system of equations. You can do that by, for example, substituting x = 50 - y in the second equation and solving for y. Then, substitute y's value back into the first equation to get x.

The solution to this system will give you the weights of mocha and java coffee beans needed to make your desired blend.

Answer:

Question 1: A. 2

Question 2: C. [tex]x>90[/tex]

Step-by-step explanation:

Question 1:

Amount to be spend = $625

Cost to rent the ball room for 3 hrs = $350

Cost of each additional hour = $125

Ms Jensen wrote the Inequality as,

[tex]625>350+125h[/tex]

h⇒ Number of additional hours.

We need to find the value of 'h'.

Solution:

[tex]625>350+125h[/tex]

Now Subtracting both side by 350 using subtraction property of Inequality we get;

[tex]625-350>350+125h-350\\\\275>125h[/tex]

Dividing both side by 125 using Division property of Inequality we get;

[tex]\frac{275}{125}>\frac{125h}{125}\\\\2.2>h[/tex]

Hence The value of 'h =2' make the Inequality true.

Question 1:

Given:

[tex]20+2<\frac{x}{3}-8[/tex]

We need to find the solution for Inequality.

Solution:

First we will add the like terms we get;

[tex]22<\frac{x}{3}-8[/tex]

Now Adding both side by 8 using addition property of Inequality we get;

[tex]22+8<\frac{x}{3}-8+8\\\\30<\frac{x}{3}[/tex]

Now multiplying both side by 3 Using multiplication property of Inequality we get;

[tex]30\times3<\frac{x}{3}\times 3\\\\90<x[/tex]

Hence The solution to given Inequality is [tex]x>90[/tex].
