William left his house at time zero and drove to the store, which is 8 blocks away, at a speed of 2 blocks per minute. Then he stopped and went into the store for 2 minutes. From there, he drove in the same direction at a speed of 4 blocks per minute until he got to the bank, which is 16 blocks away from the store. He stopped at the bank for 5 minutes. Then he drove home at a speed of 12 blocks every minute. Make a graph showing the number of blocks away from home that William is x minutes after he leaves his house, until he get back home.

Answer:

x = -20

Step-by-step explanation:

1) Isolate x

-2.5x - 10 = 40

+ 10 + 10

-2.5x = 50

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

-2.5 -2.5

x = -20

Answer:

x=-20

Step-by-step explanation:

-2.5x -10=40

-2.5x -10+10=40+10

-2.5x=50

-2.5x/-2.5=50/-2.5

x=-20

Answer:

After solving the compound inequality [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex] we get [tex]\mathbf{x>5 \ or \ x<-4}[/tex]

Option B is correct.

Step-by-step explanation:

We are given compound inequality: [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex]

We will first solve the inequalities to find the value of x, then will draw the graph.

[tex]1.5x-1>6.5 \ or \ 7x+3<-25\\1.5x-1+1>6.5+1 \ or \ 7x+3-3<-25-3\\1.5x>7.5 \ or \ 7x<-28\\x>\frac{7.5}{1.5} \ or \ x<\frac{-28}{7}\\x>5 \ or \ x< -4[/tex]

So, after solving the compound inequality [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex] we get [tex]\mathbf{x>5 \ or \ x<-4}[/tex]

Now, the number line will be as shown in figure.

The description as given in options is:

A number line goes from negative 10 to positive 10. An open circle appears at negative 4 and positive 5. The number line is shaded from negative 4 toward negative 10. The number line is also shaded from positive 5 toward positive 10.

so, Option B is correct.

Answer:

  (-5,1)

Step-by-step explanation:

To eliminate x, multiply the first equation by 3 and add 2 times the second equation.

  3(-2x +7y) +2(3x -4y) = 3(17) +2(-19)

  -6x +21y +6x -8y = 51 -38

  13y = 13

  y = 1 . . . . . matches the third answer choice

Answer: First of all thats wrong. 1/2 + 10 = 10 1/2 and 1/4 + 54 = 54 1/4

Step-by-step explanation:

The point that is scored by Mabel will be 52 points.

Based on the information given, since Phoebe scored 10 points less on her math test than Nancy and scored 23 points, then Nancy will have:

= 10 + 23 = 33 points

Since Mabel scored 19 points more on her math test than Nancy, then, the point that is scored by Mabel will be:

= 33 + 19

= 52 points

The ratio, [tex] \frac{opposite}{adjacent} [/tex], used by Hannah is the formula for calculating tangent of an angle.

Given :

There are 36 tickets sold for a raffle for the Student Art Auction, and there are two prizes to be awarded.

Dionte buys two tickets.

To Find :

The probability that he will win both price.

Solution :

Number of prizes available, p = 2

Probability of getting price from first draw :

[tex]P_1=\dfrac{2}{36}\\\\P_1=\dfrac{1}{18}[/tex]

Probability of getting price from second draw if he won first prize :

[tex]P_2=\dfrac{2-1}{36-1}\\\\P_2=\dfrac{1}{35}[/tex]

So, probability of winning both prize :

[tex]P=P_1\times P_2\\\\P=\dfrac{2}{36}\times \dfrac{1}{35}\\\\P=0.00159[/tex]

Therefore, probability of winning both prize is 0.00159 .

Answer:The slope of a line measures the steepness of the line. Most of you are probably familiar with associating slope with "rise over run". Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point. On the graph, that would mean a change of x values.

Answer:

h= 14

Step-by-step explanation:

7h-5(3h-8)= -72  PEDMAS Parenthesis first

7h-15h+40= -72 combine like terms

-8h+40= -72  subtract 40 from both sides

-8h=-112  divide by -8

h=14

The required simplified solution of the given expression is h = 4.

Given that,
A number of instruction has been added in the question, guiding the solution of the given expression.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
7h-5(3h-8) = -72

Simplify,
7h -5×3h - 5× -8 = -72
7h -15h + 40 = -72
8h = -72 + 40
-8h = -32
h = 4

Answer:

A

Step-by-step explanation:

(0, 2) is the y intercept of the given graph, option B is correct.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The line is passing through the points (3, 0) and (0,2)

We have to find the slope

m=2/-3

=-2/3

Now let us find y intercept

0= -2/3(3) +b

b=2

Hence, (0, 2) is the y intercept of the given graph, option B is correct.
