What is the slope intercept form of a line perpendicular to the line y= -3/2x -7 which passes through (-3,-4)?

Answer:

Step 3: He should have divided both sides by −7

Step-by-step explanation:

Incorrect calculation

−7x + 25 = 48

Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23

Step 3: negative seven times x over seven = twenty-three over seven

-7*x/7 = 23/7

-7x/7 = 23/7

Step 4: x = twenty-three over seven

Correct calculation

−7x + 25 = 48

Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23

Step 3: negative seven times x over seven = twenty-three over seven

-7*x/-7 = 23/-7

-7x/-7 = 23/-7

Step 4: x = twenty-three over negative seven

x = -23/7

Answer:

y=1.75x + 5.00

Step-by-step explanation:

Answer:

C. y = -2/3x -2

Step-by-step explanation:

We know the slope is negative. You can find slope using rise/run. The y-intercept is -2 because the line meets -2 at the y-intercept.    

Answer:

The first answer (top)

Step-by-step explanation:

Standard form is ax+by=c

a and b are the coefficients

Take a point from the given line

I chose (0, -2)

Then, plug in the values of x and y

2*0+3*-2=-6

-6=-6

Since it works the standard form of the line is 2x+3y=-6

Step-by-step explanation:210 games

14+13+12... (x2)

The total number of games played is 182.

The number of possible arrangements for a given set is calculated mathematically using permutation, where the arrangement's order matters.

Given that, there are 14 teams and each team plays twice with the other team.

Since each team plays every other team twice, the total number of games is nothing but the permutation of 2 out of 14 which is given by:

₁₄P₂

=14!/((14-2)!)

= (14×13×12!)/ 12!

= 14×13

=182

Hence, the total number of games played is 182.

Answer:

x=1, y=2

Step-by-step explanation:

1) 8x+3y=14 Original system of linear 2d equations

   2x+y=4

2)     8x+3y=14

   -4 (2x+y) =-4(4)   Multiply second equation by negative four.

3)    8x+3y=14

  +  -8x-4y=-16   Add equations, eliminating x terms

4) -y=-2

     y=2 solve for y

5) 8x+3(2)=14 Substitute solution for y to solve for x

Answer:

Step-by-step explanation:

A terminating decimal has an equivalent denominator that is a power of 10. That is, it is the product of a power of 2 and a power of 5.

Any fraction that has a denominator that is a power of 2 can be expressed as an equivalent fraction with a power of 10 as the denominator.

Example:

  [tex]\dfrac{7}{2048}=\dfrac{7}{2^{11}}=\dfrac{7\cdot5^{11}}{2^{11}\cdot5^{11}}=\dfrac{7\cdot5^{11}}{10^{11}}=0.00341796875[/tex]

Answer:

y = 3x - 2

Step-by-step explanation:

Step 1: Look at the "y" axis and see what it is going through (-2)

Step 2: Check if the line if a positive slope or a negative slope (positive)

Step 3: Since we now know this is a positive slope, it cancels out "D" and "A".

Step 4: This would not be B because the rise is "1" and the run is "3"

Final Ansr: "C" because the rise is "3" and the run is "1" with a "-2" y-intercept.

Answer:

$3375 money would the student council have in four years if they invest $3000 at 5% interest compounded yearly.

Step-by-step explanation:

We are given:

Principal Amount = $3000

Interest Rate r = 5% or 0.05

n=1 (compounded yearly)

Years t= 4

We need to find future value (A)

The formula used is: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Putting values in formula and finding future value A

[tex]A=P(1+\frac{r}{n})^{nt}\\A=3000(1+\frac{0.05}{1})^{1*4}\\A=3000(1+0.05)^4\\A=3000(1.05)^4\\A=3000(1.215)\\A=3375[/tex]

So, $3375 money would the student council have in four years if they invest $3000 at 5% interest compounded yearly.

Answer:

I think its 183 1/3

It's what I figured out & the other answer says the same.

Step-by-step explanation:

You like TommyInnit, too? Poggers! <3

Answer:

183 1/3

Step-by-step explanation:

I'm assuming that x and y are directly proportional.

So anyways:

5.5 divided by 3/4 is 7 1/3.

Because this is directly proportianol, you'll also have to mutiply y by 7 1/3.

So: 25 times 7 1/3 equal to 183 1/3

x = 10 hours

Each works 10 hours. Their total is 84 dollars each.

Answer:

Step-by-step explanation:

Needs $500  Makes 7.50 and works 10 hours week.

7.50*10= $75.00 a week

500/75= 6.6 weeks or 6 weeks and 2/3 of a week. I'd round to 7 weeks.

75(x)=500   X= weeks needed.

75x=500 if you divide 500 by 75

Answer:

The ordered pairs are;

(-1,1) and (-2,3)

Step-by-step explanation:

Here, we want to select which ordered pair is not a solution to the given equation

The one that will not be a solution will be a point at which if we insert the x-value into the equation, we do not get the y-value at that point

For (3,7

2(3) + 1 = 7

For 0,1

2(0) + 1 = 1

For (-1,1)

= 2(-1) + 1 = -2 + 1 = -1

This is wrong

(-3,-5)

= 2(-3) + 1 = -6 + 1 = -5

(-2,3)

= 2(-2) + 1 = -4 + 1 = -3

This is wrong also

Step-by-step explanation:

[tex] \because \angle JKM [/tex] is the exterior angle of [tex] \triangle KLM [/tex]

[tex] \therefore [/tex] by remote interior angle theorem of a triangle, we have:

[tex] m\angle L + m\angle M = m\angle JKL \\\\

(18z + 3)\degree + (5z - 3)\degree = 161\degree \\\\

(18z + 3+5z - 3)\degree = 161\degree \\\\

(23z)\degree = 161\degree \\\\

23z = 161\\\\

z = \frac{161}{23} \\\\

\huge \red {\boxed {z = 7}} \\\\

\because \measuredangle L = (18z +3)\degree \\\\

\therefore \measuredangle L = (18\times 7+3)\degree \\\\

\therefore \measuredangle L = (126+3)\degree \\\\

\huge\purple {\boxed {\therefore \measuredangle L = 129\degree}} \\\\

\because \measuredangle M = (5z - 3)\degree \\\\

\therefore \measuredangle M= (5\times 7-3)\degree \\\\

\therefore \measuredangle M = (35-3)\degree \\\\
