what points do i have to put ? please help

let's say

A(-3,1) B(-3,5) C(4,1)

we need to find the perimeter of ABC for that we find each of the sides

AB BC and AC

there is a formula to find the distance between 2 poins

let's say that a point has the structure A(x1,y1) where x=-3 and y=1 and B(x2,y2) where x2=-3 and y2=5

AB=[tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

AB=[tex]\sqrt{(-3+3)^2+(5-1)^2}[/tex]

AB=[tex]\sqrt{0^2+4^2}[/tex]

AB=4

we do the same thing for AC and BC

AC=[tex]\sqrt{(4+3)^2+(1-1)^2}[/tex]

AC=[tex]\sqrt{7^2+0^2}[/tex]

AC=7

BC=[tex]\sqrt{(4+3)^2+(1-5)^2}[/tex]

BC=[tex]\sqrt{7^2+(-4)^2}[/tex]

BC=[tex]\sqrt{49+16}[/tex]

BC=[tex]\sqrt{65}[/tex]

The perimeter is equal to the sum of the sides

P=AB+AC+BC=4+7+[tex]\sqrt{65}[/tex]=11+[tex]\sqrt{65}[/tex]

Step-by-step explanation:

Given as :

The time period for the car loan = t = 2 years

The rate of interest applied = r = 6% at simple interest

The interest amount = S.I = $264

Let The principal amount which Elsa borrowed = $p

Now, From simple interest method

Simple Interest = 

Or, S.I = 

Or, $264 = 

Or, $264 × 100 = 12 × p

Or,  p = 

∴ p = $2200

So, The principal she borrowed = p = $2200

Hence,The Principal amount that Elsa borrowed for the car loan is $2200 . Answer

Answer:

The sign is negative

Step-by-step explanation:

Given

[tex]Expression = 3xy[/tex]

[tex]x > 0[/tex]

[tex]y<0[/tex]

Required

Determine the sign

The expression can be split into 3 factors

[tex](3) (x) (y)[/tex]

If x > 0 then x is positive and If y < 0 then y is negative

So, the expression becomes:

[tex](+3) (+x) (-y)[/tex]

Leave only signs

[tex](+) (+) (-)[/tex]

[tex]+ * + = -[/tex]

So, we have:

[tex](+*+) (-)[/tex]

[tex](+) (-)[/tex]

[tex]+ * - = -[/tex]

So, we have:

[tex](+) (-) = -[/tex]

Hence, the sign of the expression is negative

Take for instance;

[tex]x = 2[/tex]

[tex]y = -4[/tex]

The expression would be:

[tex]3 *2 * - 4 =-24[/tex] -- negative

Answer:

well -4 is your x so we are going to go 4 units to the left. Then were gonna point it right there because your y value is 0 and will stay there.

Answer:

P = (18a+10b+13) cm

Step-by-step explanation:

Given that,

A triangle has the lengths of (10a+9) cm, (8a—3) cm and (10b+7) cm.

We need to find an expression that represents the perimeter of the triangle.

Perimeter = sum of all sides

P = (10a+9) + (8a-3) + (10b+7)

Taking like terms together,

P = (10a+8a)+10b+(9-3+7)

= 18a+10b+13

Hence, the epresssion for the perimeter is (18a+10b+13) cm.

Answer:

see explanation

Step-by-step explanation:

Given

3x² + 2y² = 24

To find the x- intercepts , let y = 0 in the equation and solve for x

3x² + 2(0)² = 24, that is

3x² = 24 ( divide both sides by 3 )

x² = 8 ( take the square root of both sides )

x = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ← x- intercepts

To find the y- intercepts. let x = 0 in the equation and solve for y

3(0)² + 2y² = 24 , that is

2y² = 24 ( divide both sides by 2 )

y² = 12 ( take the square root of both sides )

y = ± [tex]\sqrt{12}[/tex] = ± 2[tex]\sqrt{3}[/tex] ← y- intercepts

Answer: 15.7828283 miles

Step-by-step explanation: 5280*12 = 63360. There are 63360 inches in 1 mile. 1000000/63360=15.7828283

Options:

A. [tex]y-1 = 4(x + 8)[/tex]

B. [tex]y = -4x + 15[/tex]

C. [tex]16x + 4y = 9[/tex]

D. [tex]y=-4x[/tex]

E. [tex]4x + 2y = 3[/tex]

Answer:

B. [tex]y = -4x + 15[/tex]

C. [tex]16x + 4y = 9[/tex]

D. [tex]y=-4x[/tex]

Step-by-step explanation:

Given

[tex]8x + 2y = 7[/tex]

Required

Select all equations that could be used.

Equation that could be used in place of [tex]8x + 2y = 7[/tex] must have the same slope.

Calculating the slope of [tex]8x + 2y = 7[/tex]

Make y the subject

[tex]2y = 7 - 8x[/tex]

[tex]y = \frac{7}{2} - \frac{8x}{2}[/tex]

[tex]y = \frac{7}{2} - 4x[/tex]

[tex]y = - 4x + \frac{7}{2}[/tex]

Using y = mx + b

Where

[tex]m = slope[/tex]

The slope is -4

Option A.

[tex]y-1 = 4(x + 8)[/tex]

Open bracket

[tex]y - 1=4x + 32[/tex]

Collect Like Terms

[tex]y - 4x = 32 + 1[/tex]

[tex]y - 4x = 33[/tex]

Make y the subject

[tex]y = 4x + 33[/tex]

The slope of this line is 4;

Hence, it can not be used.

Option  B.

[tex]y = -4x + 15[/tex]

The slope of this line is -4;

Hence, it can be used.

Option  C.

[tex]16x + 4y = 9[/tex]

Solve for4y

[tex]4y=9 - 16x[/tex]

Solve for y

[tex]\frac{4y}{4} =\frac{9}{4} - \frac{16x}{4}[/tex]

[tex]y =\frac{9}{4} - 4x[/tex]

[tex]y = - 4x + \frac{9}{4}[/tex]

The slope of this line is -4;

Hence, it can be used.

D. [tex]y=-4x[/tex]

The slope of this line is -4;

Hence, it can be used.

E. [tex]4x + 2y = 3[/tex]

Solve for 2y

[tex]2y = 3 - 4x[/tex]

Solve for y

[tex]\frac{2y}{2} = \frac{3}{2} - \frac{4x}{2}[/tex]

[tex]y = \frac{3}{2} - 2x[/tex]

The slope of this line is -2;

Hence, it can not be used.

From the calculations above, equations B, C and D are equivalent

Answer:

slope is 5

Step-by-step explanation:

Answer: 5

Step-by-step explanation:

(4,3) (2,-7)

Put it in the equation of y2 - y1 over x2 - x1

-7-3 = -10 and 2 - 4 = -2 that will give you the fraction of -10/-2

Reduce the fraction and that will give you the answer of 5, slope = 5

In slope-intercept form it would be y - 3 = 5 (x - 4)

Hope this helps! ^^

Answer:

Step-by-step explanation:

Apply the slope formula to be sure. The slope formula is

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

Filling in with our coordinates gives us:

[tex]m=\frac{-2-10}{-2-4}=\frac{-12}{-6}=2[/tex]

The slope is 2. If you don't want to use the slope formula you could just look at the line and pick 2 points the line goes through and use a slope triangle, but that's a bit more difficult to explain without the benefit of being there to point out the idiosyncrasies of it.

Answer:

x = 11

Step-by-step explanation:

3/6=5.5/x

Cross multiply.

3 * x = 6 * 5.5

x = 2 * 5.5

x = 11

Answer:

The answer is x=−2y+4

Step-by-step explanation:

1) Add -4y to both sides.

2x+4y+−4y=8+−4y

2x=−4y+8

Step 2: Divide both sides by 2.

2x/2=−4y+8/2

x=−2y+4

Given :

A college cafeteria pays student cashiers $540 per hour. Cashiers earn an additional  $110 per hour for each hour worked over 35 hours per week.

To Find :

A cashier worked 39  hours one week and 37 hours the second week.

Show and explain to the cashier how her salary calculated in this two-week period.

Solution :

Week 1 :

For first 35 hours he will get fixed amount i.e $540.

Now, for next four hours he will get $110 per hour.

So, total salary, T = 540 + (110×(39 - 35)

T = $980

Week 2 :

Total salary, T = 540 + ( 110×( 37 - 35 ))

T = $760

Therefore, salary of two week period is $( 980 + 760 ) = $1740.

Answer:

  c) 5n +25q = 365

     2q -4 = n

Step-by-step explanation:

The number of nickels (n) is 4 less than twice the number of quarters (q), so one of the equations is ...

  2q -4 = n

The face value is 365 cents, so another equation is ...

  5n +25q = 365

These equations seem to match choice C.

Step-by-step explanation:

i love you more than you know:( <3

see you someday

The compound inequality which represents the given situation is 20 < x < 30.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Let's say x represents the spend.

As per the given,

You can spend less than $30,

x < 30

You must also spend more than 20.

x > 20

Compound,

30 < x < 20

Hence "The compound inequality which represents the given situation is 20 < x < 30".

Answer:

Henny = (x-8) dollars

Step-by-step explanation:

Janet's has x dollars.

Henny has $8 less than Janet. It means, the difference between the dollars own by Janet's and Henny is 8.

Henny has = (x-8) dollars

Hence, the expression that shows dollars Hanley has is (x-8).
