I need help anyone??!

Answer:

I believe its -7/5 unless they want -7/-5

Step-by-step explanation:

(4,3) (-1,-4)

X1,y1 x2,y2

And it should be

Y2-y1

X2-x1

-4-3 = -7

Over

-1-4 = -5

So -7/5 or -7/-5 whatever your teacher perfers

Answer:

The slope of the line is  [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Given parameters:

                       A(-4, -1) to B(4, 2)​

Unknown:

The slope of the line joining the two points

Solution:

To find the slope of the line;  we use the expression below:

  Slope  = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]

x₁ = -4

y₁ = -1

x₂ = 4

y₂ = 2

Input the parameters and solve;

      Slope  = [tex]\frac{2 -(-1)}{4-(-4)}[/tex]

     Slope  = [tex]\frac{3}{8}[/tex]

The slope of the line is  [tex]\frac{3}{8}[/tex]

Answer:

50.3 cm³

Step-by-step explanation:

Use the cylinder volume formula:

V = [tex]\pi[/tex]r²h, where r is the radius and h is the height.

Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.

Plug in the radius and height into the equation:

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](2²)(4)

V = 16[tex]\pi[/tex]

V = 50.3 cm³

Answer:

50.3 cm³

Step-by-step explanation:

Use the cylinder volume formula:

V = r²h, where r is the radius and h is the height.

Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.

Plug in the radius and height into the equation:

V = r²h

V = (2²)(4)

V = 16

V = 50.3 cm³

Answer:

m = 7

Step-by-step explanation:

The 3 given angles lie on a straight line, thus sum to 180° , then

8m - 4 + 90 + 5m + 3 = 180, that is

13m + 89 = 180 ( subtract 89 from both sides )

13m = 91 ( divide both sides by 13 )

m = 7

Answer:

P= $2.75

Step-by-step explanation:

So first we need to create our system of equations

since each popcorn is 0.40 less than each drink we can make the equation:

D - 0.40 = P we can rewrite that as P + 0.40 = D so that we have D by its self.

Next, we create the overall equation:

$24.00 = 3P + 5D

Now plug in D from the first equation into the second equation:

$24.00 = 3P + 5( P + 0.40)

Distribute the five and solve for P:

$24.00 = 3P + 5P + 2

$22.00 = 8P

P = $2.75

Now add 0.40 which would be $3.15 and plug it into the first equation just to make sure that the answer is correct.

Answer:

Let x=the smaller integer.

Let x+1+ the larger integer.

x+(x+1)=173

(x+x)+1=173

2x+1=173

2x+1-1=173-1 (substract 1 from both sides)

2x=172 (divide 2 to both sides)

2x/2=172/2

x=86

x+1=87

Answer:

Equation: X × 0.4 + (10 - X)×0.05 = 10 × 0.2

Solution: 5.71 liters of 5% and 4.29 liters 40%

Step-by-step explanation:

The volume of the 20% acid solution the scientist needs = 10 liters

The concentration of the solution she has = 5% and 40%

Therefore, we have;

X volume of the 40% solution is mixed with 10 - X volume of the 5% solution, to obtain 10 liters of the 20% solution

Therefore, we have;

Equation: X × 0.4 + (10 - X)×0.05 = 10 × 0.2

0.4·X + 0.5 - 0.05·X = 2

0.35·X = 2 - 0.5 = 1.5

X = 1.5/0.35 = 30/7

∴ The volume of the 40% solution = 30/7 liters ≈ 4.29 liters

The volume of the 5% solution = 10 - X = 10 - 30/7 = 40/7 liters ≈ 5.71 liters

Therefore, we have;

5.71 liters of 5% solution and 4.29 liters 40% solution.

Answer: 1406.25

Step-by-step explanation:

The soccer field at a park is 9,000 square yards. The soccer field takes up 6 2/5 square inches on the map of the park. How many square yards does 1 square inch on the map represent? Show your work. Help me pls

Given that:

Area of soccer field = 9000 sq yards

Soccer field takes up 6 2/5 square inches on the map of park

Hence,

9000 yd² = 6 2/5 in²

Let 1 in² on map = m

9000 yd² = 32/5 in² - - - (1)

m = 1 in² - - - (2)

Cross multiply ;

6.4 * m = 9000

m = 9000/6.4

m = 1406.25

Hence,

1 in² on map = 1406.25 feet²

Answer:

x=9

Step-by-step explanation:

Subtract 8 from both sides.

−5x=−37−8

Subtract 8 from −37 to get −45.

−5x=−45

Divide both sides by −5.

x= -45/-5

Divide −45 by −5 to get 9.

x=9

Answer:

9

Step-by-step explanation:

Step 1:

8 - 5x = - 37       Equation

Step 2:

8 = - 37 + 5x     Add 5x on both sides

Step 3:

45 = 5x      Add 37 on both sides

Step 4:

x = 45 ÷ 5     Divide

Answer:

x = 9

Answer:

a. 13.7084 oz.

Step-by-step explanation:

Formula for Lower Control Limit =

(LCL = x-bar - A²R-bar)

x - bar = 14 oz

A2 = 0.729

R - bar = 0.4 oz

= 14 - 0.729 × 0.4

= 14 - 0.2916

= 13.7084oz

Answer: 45 students

Step-by-step explanation:

Company A’s charge can be represented by: 4s+60

Company B’s charge can be represented by: 2s+150

s is the charge per student

To find the cost at which they are the same, I will set both equations equal to each other.

4s+60=2s+150

-2s -2s

2s+60=150

-60 -60

2s=90 Divide both sides by 2

s=45

So when 45 students are going, the cost for both companies are the same.

Answer:

C. 3x^2 + 2x + 1

Step-by-step explanation:

A. 12^2 - (4*3*12) = 0 (there's one solution.)

B. (-3)^2 - (4*3*-18) = 255 (there're 2 real solutions.)

D. 3^2 - (4*0*-3) = 9 (there're 2 real solutions.)

C. 2^2 - (4*3*1) = -18 ✅✅

if b^2 - 4ac = negative then we can say that there isn't any real solution for the equation.

Answer:

34

Step-by-step explanation:

10+2=12

12 on both sides=24

5 on both sides=10

10+24=34

The perimeter of the rectangle is 34 for the given sides.

The rectangle is defined as a quadrilateral having four sides and the angle suspended by all the sides is equal to 360 degrees. The perimeter is the sum of all the sides of the rectangle.

Given that the two sides of the rectangle are 5 and x + 2. The value of x is 10.

The perimeter of the rectangle will be calculated as:-

L = 10+2=12

12 on both sides=24

5 on both sides=10

Perimeter = 10+24=34

Therefore, the perimeter of the rectangle is 34 for the given sides.

Answer:

uhh precious why u stalkin me????

Step-by-step explanation:

==========================================

Work Shown:

The given angles are a linear pair, so they are supplementary.

(1+5x)+(3+3x) = 180

1+5x+3+3x = 180

(5x+3x)+(1+3) = 180

8x+4 = 180

8x+4-4 = 180-4 .... subtract 4 from both sides

8x = 176

8x/8 = 176/8 ..... divide both sides by 8

x = 22

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

Extra info:

1+5x = 1+5*22 = 1+110 = 111

3+3x = 3+3*22 = 3+66 = 69

111+69 = 180, which helps confirm the answer.
