Step-by-step explanation:

210 ÷ [ 5 + 16 ÷ 2 { 6 - 18 ÷ ( 7 + 2 ) } ] - 15

210 ÷ [ 5 + 16 ÷ 2 { 6 - 18 ÷ 9 } ] - 15

210 ÷ [ 5 + 16 ÷ 2 { 6 - 2 } ] - 15

210 ÷ [ 5 + 16 ÷ 2 { 4 } ] - 15

210 ÷ [ 5 + 16 ÷ 8 ] - 15

210 ÷ [ 5 + 2 ] - 15

210 ÷ 7 - 15

Answer:

-\frac{345}{37}

Step-by-step explanation:

Just follow the order of operations

210÷[5+16÷2{6−18÷(7+2)}]−15  

= 210÷[5+16÷2{6−18÷9}]−15   (calculate 7+2)

= 210÷[5+16÷2{6−2}]−15 (calculate 18÷9)

= 210÷[5+16÷2{4}]−15  (calculate 6-4)

= 210÷[5+16÷2×4]−15

= 210÷[5+8×4]−15  (calculate 16÷2)

= 210÷[5+32]−15  (calculate 8×4)

= 210÷[37]−15  (calculate 5+32)

= 210÷37−15

= 210÷37−(15×37)÷37  (put on the same denominator)

= 210÷37−555÷37  (calculate 15×37)

= (210−555)÷37

=-345÷37   (calculate 210-555)

Suppose the function F(c) represents the earnings of a volleyball team from selling c cupcakes. They are selling each cupcake fo
navik [9.2K]

Answer:

The variable c represents the domain as it is the independent variable.

The domain of the function F(c) is given by c ≥ 0.

So, only positive values for the input make sense.

The upper limit of the domain is +∞ and lower limit is 0.

It is not possible for the team to earn $50.50 as it will be only multiple of 2.

Step-by-step explanation:

If F(c) represents the earning of a volleyball team from selling c cupcakes and each cupcake costs $2 each, then the equation that models the situation is  

F(c) = 2c ..... (1)

The variable c represents the domain as it is the independent variable. (Answer)

The domain of the function F(c) is given by c ≥ 0. (Answer)

So, only positive values for the input make sense. (Answer)

The upper limit of the domain is +∞ and the lower limit is 0. (Answer)

It is not possible for the team to earn $50.50 as it will be only multiple of 2. (Answer)

A line is defined by the equation 2x+y -4. Which shows the graph of this line?
Nitella [24]

Answer:

Not sure if you mean 2x+y=-4 or 2x+y=4

either way put it in y=mx + b form (slope intercept)

Step-by-step explanation:

so for 2x+y = -4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ -4 so m= -2/1 (slope) and b= -4 the place the line crosses the y axis

so for 2x+y = 4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ 4 so m= -2/1 (slope) and b= 4 the place the line crosses the y axis

find an equation of the line passing through the point (5 4) and parallel to the line whose equation is y= 2x-6
yKpoI14uk [10]

Answer:

y = 2x - 6

Step-by-step explanation:

Given

Equation: y = 2x - 6

Required

Determine the equation of Point: (5,4)

First, we need to determine the slope of y = 2x - 6

The general form of an equation is y = mx + b

Where m represents the slope;

Hence; m =2

Since the equation and the point are parallel. then they have the same slope (m).

m = 2

Next, is to determine the equation of the point, using the following formula:

m = \frac{y - y_1}{x - x_1}

Where

(x_1,y_1) = (5,4)

So, the equation becomes

2 = \frac{y - 4}{x - 5}

Cross Multiply

y - 4 = 2(x - 5)

Open Bracket

y - 4 = 2x - 10

Make y the subject of formula

y = 2x - 10 + 4

y = 2x - 6

Hence, the equation is y = 2x - 6

What is the equation of the axis of symmetry of this parabola? y=-5(x+4)^2+3
Ede4ka [16]

Answer:

x=-4

Step-by-step explanation:

Given the equation of parabola

y=-5(x+4)^2+3

This is the vertex form of the parabola equation. Hence, the vertex of the parabola is at point (-4,3)

This parabole goes downwards in y-direction (the leading coefficient -5 is negative)

<u>The axis of symmetry</u> of parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Thus, the equation of the axis of symmetry is

x=-4
