Slope-Intercept Form: y = mx + b

Step-by-step explanation:

Step 1: Define

Slope m = 10

y-intercept b = 0

Step 2: Write function

Plug in variables into the general form.

y = 10x + 0

y = 10x

Answer:

y = 10x

Step-by-step explanation:

Equation of a line: y = mx + b

y = 10x + 0 is also y = 10x

Answer:

The value of x is -1 when h(x) = 0

Step-by-step explanation:

Given function is:

[tex]h(x) = 4x+4[/tex]

The function is a linear function with one input.

We have to solve for x when h(x) = 0 this means that we have to put h(x) = 0 and find the value of x.

So,

[tex]h(x) = 0\\4x+4 = 0[/tex]

Subtracting 4 from both sides

[tex]4x+4-4 = 0-4\\4x = -4[/tex]

Dividing both sides by 4

[tex]\\\frac{4x}{4} = \frac{-4}{4}\\x = -1[/tex]

Hence,

The value of x is -1 when h(x) = 0

Answer:

See attached graph, and answers.

Step-by-step explanation:

The inequalities are given as;

i) y>3x+10

ii) y<-3/4x -1

Graphing the inequalities gives the following result

The solution area is that which is shaded and the lines are broken lines not complete

From the graph the solution is:  { -2.9,1.2}

The point {8,10} is not a solution to the system. This is because it is not in the shaded area that represent the solution to the inequalities.

Answer:

32

Step-by-step explanation:

Factorize:

64= 2x2x2x2x2x2

160= 2x2x2x2x2x5

224=2x2x2x2x2x7

If you notice, the pairs have 5 2s. So the gcf is 2^5 or 32.

Hope this helps plz hit the crown :D

The greatest common factor of 64,160, and 224 will be 32.

The greatest common factor is the largest positive number which can be divided into given numbers evenly. The greatest common factor is the highest number which divides all the given numbers completely.

Given numbers 64, 160 and 224. The greatest common factor is calculated by factorizing the given numbers.

Factorize number 64.

64 = 2x2x2x2x2x2

Factorize the number 160.

160 = 2x2x2x2x2x5

Factorize the number 224.

224 = 2x2x2x2x2x7

The common number between all three numbers is 2² or 32. Therefore, the greatest common factor of 64,160, and 224 will be 32.

Answer:

1250 Kilometers.

Step-by-step explanation:

Start by finding the proper ratio of 5000:6. Now divide 6/1.5 to see what we need to divide 5000 by. 6/1.5 is 4. So divide 5000 by 4. This gives you an answer of 1250 kilometers.

Answer:

[tex]1250km[/tex]

Step-by-step explanation:

To find how far the plane can travel in [tex]1.5[/tex] hours, we need to first find the speed of the plane.

It is given that the plane can travel [tex]5000[/tex] kilometers in 6 hours, so the following equation can be written:

[tex]s = 5000km/6hours[/tex] ([tex]s[/tex] refers to the speed of the plane)

[tex]= 833\frac{1}{3}km/hour[/tex]

To find how far the plane travels in [tex]1.5[/tex] hours, we can multiply the distance it travels in 1 hour to [tex]1.5[/tex] hours:

Distance travelled [tex]= 833\frac{1}{3}\times 1.5[/tex]

[tex]=1250km[/tex]

Answer:

y = -7x + 30

Step-by-step explanation:

Answer:

x = -2, y = -4

x = -1, y = -1

x = 0, y = 2

x = 1, y = 5

Step-by-step explanation:

Just apply the formula into the different values for x.

x = -2

y = 3(-2) + 2

  = -6 + 2

  = -4

x = -1

y = 3(-1) + 2

  = -3 + 2

  = -1

x = 0

y = 3(0) + 2

  = 0 + 2

  = 2

x = 1

y = 3(1) + 2

  = 3 + 2

  = 5

Given that the angle m∠PQR has angles m∠PQS and m∠SQR arranged adjacent to each other while sharing the same boundary segment, QS we have by the angle addition postulate;

m∠PQR is the sum of the angles m∠PQS and m∠SQR, therefore;

m∠PQR = m∠PQS + m∠SQR = 90°.

The events of picking marbles from the jar is independent

An event is independent if the occurrence of one event does not depend on another event.

For example, if you toss a coin and it lands on its head. You then flip another coin and it lands on its tail. These two events are independent. The face the second coin lands on do not depend on which face the first coin lands on. Also, the face that the first coin lands on does not depend on which face the second coin lands on.

In this question, after the first marble is picked, you do not return the first marble into the jar. Then you pick a second marble. The colour of the second marble does not depend on the colour of the first marble you picked. This means that the events are independent.

Answer:

The width of the rectangle is 20 inches.

Step-by-step explanation:

Since the ratio of length to width is 6:5, the width will be 5/6 of the length. To find 5/6 of 24, multiply 24/1 by 5/6 and simplify. (24/1 is the fraction form of 24 and makes solving the problem a little easier.)

— 24/1 * 5/6 = 120/6

— 120/6 = 20

The width of the rectangle is 20 inches.

Explanation:

Look through the table to see when f(x) = g(x)

This happens when both are equal to 1, which is in the fourth row, or when x = -1.

In other words,

So f(-1) = g(-1)

We can then say the solution to f(x) = g(x) is x = -1.
