Chloe is having her birthday party at the Griffith Observatory. The observatory charges $75 and an additional $8 per person. If Chloe wants to spend at most $190, how many people can she invite?

Step-by-step explanation:

xy = k, where k is a real constant.

When y = -1/4, x = -8.

=> k = (-8)(-1/4) = 2.

Therefore when x = 4,

y = k/x = (2)/(4) = 0.5.

In an inverse variation the value of y is 0.5

What is the value of y ?

In an inverse variation, X = -8 wheny= - 1/4.

y= - 1/4.

the value of y when x = 4

In the equation xy = k, k is a real constant.

X equals -8 at y = 1/4.

=> k = (-8)(-1/4) = 2.

Consequently, if x = 4,

y = k/x = (2)/(4) = 0.5.

In an inverse variation the value of y is 0.5.

Answer:

Step-by-step explanation:

Find the lowest common multiple between the numbers

35 = 5×7

40 = 2³×5

42 = 2×3×7

So the lowest common multiple is:

2³×3×5×7 =840 minutes

840 minutes is 14 hours so the next time they are all at the interchange is 2020 hours.

Answer:

-4

Step-by-step explanation:

Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.

So to solve for x, set 28 and 10x+68 equal to each other.

28=10x+68

First, subtract 68 from both sides

-40=10x

Then, divide both sides by 10

-4=x

If you want to check your answer plug -4 back into the original equation.

28=10(-4)+68

28=-40+68

28=28, which is true, therefore -4 is correct.

Answer:

The expression uses multiplication and subtraction.

Multiplication and subtraction used in the expression 2x – 4

An expression is combination of variables, numbers and operators.

We need to find which operations are used in expression

2x-4

An operation is a mathematical action. Addition, subtraction, multiplication, division, and calculating the root are all examples of a mathematical operation.

Two times of x minus four.

Two times of x means we are taking product of 2 and x. Multiplication is used

2x-4 means we are subtracting four from 2x. Subtraction is used in the expression.

Hence Multiplication and subtraction used in the expression 2x – 4

Answer:

-3 and -4

Step-by-step explanation:

x = 1st number

y = 2nd number

set up system of equations:

2x + 3y = -18

3x + 2y = -17

elimination method:  multiply 1st equation by -2 and second by 3

 -4x - 6y = 36

+

 9x + 6y = -51

  5x = -15

   x = -3

find y:  2(-3) + 3y = -18

           -6 + 3y = -18

            3y = -12

             y = -4

Answer:

Coordinates of point R → (c - a, b)

Step-by-step explanation:

From the picture attached,

By the property of an isosceles trapezoid,

PX = AY = a

Therefore, horizontal distance of Y from the origin PY = AP - AY

PY = c - a

Vertical distance of point R from x-axis (RY) = b

Therefore, coordinates of point R will be (c - a, b).

Answer:

8 pounds

Step-by-step explanation:

Total ratio = 3 + 1 + 5 = 9

x = total pounds of chicken, beef and fish bought

equation for pounds of fish bought = 5/9 × x = 10

divide both sides by 9/5

x = 18

pounds of chicken bought = 3/9 x 18 = 6 pounds

pounds of beef bought = 1/9 x 18 = 2 pounds

total weight of meat bought = 6 + 2 = 8 pounds

The line's equation is y=x+3

4-(-1)/1-(-4)=5/5=1. That's the slope.

Answer:

1

Step-by-step explanation:

Use the following equation:

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

Let:

([tex]x_1 , y_1[/tex]) = ([tex]-4 , -1[/tex])

([tex]x_2 , y_2[/tex]) = ([tex]1 , 4[/tex])

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{4 - (-1)}{1 - (-4)}[/tex] = [tex]\frac{4 + 1}{1 + 4} = \frac{5}{5}[/tex]

[tex]\frac{5}{5} = 1[/tex]

Your slope is 1.
