Answer:

ok so they had lot of money and then they went down

Step-by-step explanation:

so i think what happen was that they started off at day 1 with 500 dollars around and then they went down to 285 and then 210 around there, so that can mean they must of wasted money on something or something else on the account

Answer:

x = 128

x - 23 = 105°

Step-by-step explanation:

x - 23° = 105° because these angles are corresponding

x = 105 + 23

x = 128

The value of the angle marked x - 23 = 105

Answer:

a. ST and UV are perpendicular lines.

b. BC and DE are parallel.

c. NP and QR are neither parallel nor perpendicular.

d. GH and JK are parallel.

Step-by-step explanation:

Slopes are used to calculate steepness of a line. Slopes are also used to check if two lines are parallel, perpendicular or neither.

When two lines are parallel, their slopes are equal.

When two lines are perpendicular, product of slopes of both lines is -1

Slope is given by the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

a) S(-4, -1), T(-1,5) and U(1,1), V(5, -1)

[tex]Slope\ of\ ST = \frac{5+1}{-1+4} = \frac{6}{3} = 2\\Slope\ of\ UV = \frac{-1-1}{5-1} = \frac{-2}{4} = -\frac{1}{2}[/tex]

Now,

[tex](Slope\ of\ ST)(Slope\ of\ UV) \\= 2 * -\frac{1}{2}\\=-1[/tex]

ST and UV are perpendicular lines.

b) B(-6, -2), C(-3, 3) and D(2,0), E(5,5)

[tex]Slope\ of\ BC = \frac{3+2}{-3+6} = \frac{5}{3}\\Slope\ of\ DE = \frac{5-0}{5-2} = \frac{5}{3}[/tex]

As the slopes of two lines is equal, BC and DE are parallel.

c) N(-6,2), P(--3, -4) and Q(1, -3), R(3, 4)

[tex]Slope\ of\ NP = \frac{-4-2}{-3+6} = \frac{-6}{3} = -2\\Slope of\ QR = \frac{4+3}{3-2} = \frac{7}{2}[/tex]

NP and QR are neither parallel nor perpendicular.

d) G(-2,5), H(4,1) and J(1, –4), K(7,0)

[tex]Slope\ of\ GH = \frac{1-5}{4+2} = \frac{-4}{6} = -\frac{2}{3}\\Slope\ of\ JK = \frac{0-4}{7-1}= \frac{-4}{6} = -\frac{2}{3}[/tex]

GH and JK are parallel.

Hence,

a. ST and UV are perpendicular lines.

b. BC and DE are parallel.

c. NP and QR are neither parallel nor perpendicular.

d. GH and JK are parallel.

Answer:

Step-by-step explanation: when you first open the graphing tool you have to click relationship and choose custom. put in gwen’s equations (y=100+10x) then go to relationship and choose custom again and put in tristan’s equation (y=12.5)

also click on the settings button at the bottom of the graph and put the x axis to -100 min and 100 max and for y axis put -1000 min and 1000 max or you could choose your own numbers but thats just what i put

The graph of the equations (y = 10x + 100), (y = 10x), and (y = 12.5x) can be drawn by using the rules of transformation.

Given :

The following steps can be used to sketch the graph of the given line (y = 100 + 10x):

Step 1 - First sketch the graph of (y = x).

Step 2 - Then Multiply the x-axis by a factor of 10. The resulting graph is the graph of (y = 10x)

Step 3 - Then find the y-intercept from the given equation. Then draw the line that passes through (0,100). The resulting line is the graph of (y = 100 + 10x).

The following steps can be used to sketch the graph of the given line (y = 10x):

Step 1 - First sketch the graph of (y = x).

Step 2 - Then Multiply the x-axis by a factor of 10. The resulting graph is the graph of (y = 10x)

The following steps can be used to sketch the graph of the given line (y = 12.5x):

Step 1 - First sketch the graph of (y = x).

Step 2 - Then Multiply the x-axis by a factor of 12.5. The resulting graph is the graph of (y = 12.5x)

The graph of all the equations together is attached below.

Answer:

TRUE

Step-by-step explanation:

In a function, every domain value (x-value) must have exactly one corresponding range value (y-value). This means that in a function, an x-value or input value cannot have two different y-value or output value. Or else, it ceases to be a function.

So, when you substitute a certain value of x into the equation of a function, you can only have one exact value of y for that value of x.

Answer: LMC= 36

Step-by-step

Lcm is were u find how much they can go into each other for example

4: 12 3 4 5 6 7 8 9 = 36

9: 1 2 3 4 = 36

3: 1 2 3 4 5 6 7 89 10 11 12 = 36

Answer:

Well, I don't know how to graph it for you, but the slope is -2/3 and the point is (-9, 5).  So, when you graph it, from the point (-9, 5), you can go 3 units to the right and 2 units down.

it depends what the number is

Answer: The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.

Step-by-step explanation:

Answer

1.) B

2.)  3 hours

Step-by-step explanation:

1.)  option B is correct I think because it shows he will either be equal to or less than how much money he wants to spend

2.) i got three because if you sent up the equal I picked in question one then you subtract 28 from 250 giving u 222 and you divide that by 65 giving you 3.4 but he only charges by the whole hour so that .4 of an hour he wouldn't charge you for
