please help me i rlly need help
Answer:
3
Step-by-step explanation:
Given a line with points; (2, 5) (3, 8).
1. Find the slope of the given line
The formula for finding the slope is:
[tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1}}[/tex]
Substitute in the values;
[tex]x_{1} = 2\\y_{1} = 5\\x_{2} = 3\\y_{2} = 8[/tex]
[tex]\frac{8-5}{3-2}[/tex]
simplify;
[tex]\frac{3}{1}[/tex]
= 3
2. Find the slope of the parallel line;
Remember, when two lines are parallel, they run alongside each other, of infinitely long, but they never touch. Hence two parallel lines have the same slope. Therefore, the slope of a line that is parallel to the given one will also have the same slope as the given one, which is 3.
pleaseeeeeeeeeeeeeeeeeeeeee help me i'm begging you so the questions is what is the multiplicative of 5 and 10-5k

A school eams S70 from selling 50 tickets for the school play. Each ticket costs the same amount
How much does the school eam for 1 ticket?
Enter your answer in the box below.
Answer:
$1.40
Step-by-step explanation:
I used a unit rate to understand it.
$70/50
70÷ 50= 1.4
50÷50=1
1.4/1 = 1.4 OR $1.40, adding a zero doesn't change it amount, it just places a filler, so the final answer is, one dollar and forty cents.

What’s the equation of a line that is perpendicular to -x +2y =4 and passes through the point (-2,1)
Answer:
y = -2x - 3
Step-by-step explanation:
Given:
Equation of -x +2y =4
Point of (-2,1)
-x + 2y = 4
y = x/2 + 2 or y = 1/2x + 2
Which means the equation's slope is m = 1/2.
The slope of the perpendicular line is negative inverse which is m = -2.
Now we have an equation of y = -2x + a.
Use (-2, 1) to find a:
1 = (-2)(-2) + a
a = -3
y = - 2x - 3

I need HELP, I'm just a dumb kid from Minnesota, I have no clue what to do...The line below has a slope of 2. Both points are on the same line. Find the values of a and b
Answer:
The values of [tex]a[/tex] and [tex]b[/tex] are 6 and 4, respectively.
Step-by-step explanation:
Geometrically speaking, any line is represented by equation of the form:
[tex]y = m\cdot x + b[/tex] (1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]m[/tex] - Slope, dimensionless.
[tex]b[/tex] - y-Intercept, dimensionless.
In addition, the slope is defined in terms of distinct known points. That is:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] (2)
If we know that [tex](x_{1},y_{1})=(4,b)[/tex], [tex](x_{2}, y_{2}) = (a, 8)[/tex] and [tex]m = 2[/tex], then the slope is:
[tex]\frac{8-b}{a-4} = 2[/tex]
[tex]8-b = 2\cdot (a-4)[/tex]
[tex]8-b = 2\cdot a -8[/tex]
[tex]b = 16-2\cdot a[/tex]
There is more than one option. If we assume that [tex]a = 6[/tex], then [tex]b[/tex] is:
[tex]b = 16-2\cdot (6)[/tex]
[tex]b = 4[/tex]
The values of [tex]a[/tex] and [tex]b[/tex] are 6 and 4, respectively.

If pand q vary inversely and pis 28 when Q is 29. determine q when p is equal to 14.
9514 1404 393
Answer:
q = 58
Step-by-step explanation:
If the variation is inverse, when p is multiplied by 1/2, q will be multiplied by the inverse (reciprocal) of 1/2, which is 2/1 = 2.
When p = (1/2)(28), q = (2)(29) = 59
q = 58

Which equation represents the line that passes through the point (4, -5) and is perpendicular to the line x + 2y = 5?
Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13

You recently discovered that your job provides a 25% matching towards your retirement.
If you deposit $300 each month into a retirement account with an APR of 8.99%, what
would you type in Excel to find the balance after 30 years?
Answer:
What is typed in the attached Excel file is =FV(B4,B5,-B3,0,0).
Step-by-step explanation:
Note: See the attached excel file for the calculation of future value of an ordinary annuity.
Since we want to find the balance after 30 years, the function in the Excel is the FV function which is used to calculate the future value (FV) of an ordinary annuity as follows:
=FV(rate,nper,-pmt,0,0) …………………… (1)
rate = Monthly interest rate = APR / 12 = 8.99% / 12 = 0.0899 / 12 = 0.00749166666666667. Note: This is typed in cell B4 in attached excel file.
nper = periods = number of months = 30 years * 12 months = 360. Note: This is typed in cell B5 in attached excel file.
pmt = monthly payment = $300. Note: This is typed in cell B3 in the attached excel file. And also typed as a negative value in cell B7, i.e. as -B3.
pv = present value = 0. Note: This is the first 0 typed in cell B7 in the attached excel file.
type 0 = 0 this is typed to indicate that deposit is made at end of period as a regular or ordinary annuity. This is the second 0 typed in cell B7 in the attached excel file.
Based on the above, the FV function in equation (1) above is converted to the following which is typed in the attached Excel file to find the balance after 30 years:
=FV(B4,B5,-B3,0,0)
The above then gives a future value of $548,080.11 which is the balance after 30 years.

Answer:
7) y = -2
8) x = 4
Step-by-step explanation:
Any straight horizontal/vertical line you find will be x= or y=. The vertical lines are always x= because they only touch the x axis. It's the opposite for horizontal lines. For example, on number 7, the line touches -2 on the y axis. That's why it's "y=-2". Same goes for 8. the line only touches 4.
I hope this helped and wasn't confusing!
