Answer:

I'm pretty sure the slope is 5/4

Step-by-step explanation:

When you graph (-8,-7) and (-4,-2) you use rise/run to find the slope.Which is essntially counting up and the over from the first point to the second. Or you can use the equation of slope. Which is y1-y2/x1-x2.

Answer:

Step-by-step explanation:

Given quadratic equation is,

y = -2x² + 4x + 5

y = -2(x² - 2x) + 5

y = -2(x² - 2x + 1 - 1) + 5

y = -2(x² - 2x + 1) + 2 + 5

y = -2(x - 1)² + 7

This equation is in the vertex form of the quadratic equation,

y = a(x - h)² + k

where, (h, k) is the vertex of the parabola.

Therefore, vertex of the given quadratic equation is (1, 7)

The equation can be rewritten as y = -2(x - 1)² + 7.

Therefore, the vertex of the graph of the function y = -2x² + 4x + 5 in the xy-coordinate plane is located at the point (1, 7).

ABCD is a parallelogram.

Measures of the opposite angles of a parallelogram are equal. Here [tex] \angle A, \:\: \angle C \: \: and\:\: \angle B, \:\: \angle D[/tex] are opposite angles.

[tex] \therefore m\angle A = m\angle C = 110\degree [/tex]

[tex] \& \:m\angle B = m\angle D = 70\degree [/tex]

[tex] m\angle A + m\angle B =110\degree + 70\degree [/tex]

The number of people that bought T-shirt is 2070 people

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"

To find the percentage of those that bought the T-shirt

We find 45% of 4,500

45/100 * 4500

2070

Hence, 2070 people out of the 4,500 people who attend the rock concert bought the T-shirt

Responder:

26 litros

Explicación paso a paso:

Dado lo siguiente

Litros totales de agua utilizados = 20 litros

El inodoro en sí contiene 6 litros de agua.

Agua total consumida = litro de agua utilizada + agua contenida en el inodoro

Agua total consumida = 20 litros + 6 litros

Agua total consumida = 26 litros

Por lo tanto, el consumo total de agua del inodoro, asumiendo que se descarga una sola vez, es de 26 litros

Answer:

x = 6

Step-by-step explanation:

Coach ticket = $180

first class ticket = $1020

people = 8

Let x be number of coach tickets

Then number of first class tickets = (8 - x)

x * 180 + (8 - x) * 1020 = 3120

180 X + 8 * 1020 - 1020 x = 3120

180 x + 8160 - 1020 x = 3120

180 x - 1020 x = 3120 -8160

- 840 x = - 5040

840 x = 5040

x = 6

So 6 coach class tickets and 2 first class tickets

Answer:

She bought 8 coach tickets

And 5 first class tickets

Step-by-step explanation:

Answer:

2x - 1

Step-by-step explanation:

Simplify. Note that you cannot combine a term with a variable with a constant term. Divide 5 from both terms in the parenthesis:

1/5(10x - 5) = (10x - 5)/5

Divide 5 from both terms in the parenthesis:

10x/5 = 2x

-5/5 = -1

2x - 1 is your answer.

Answer:

6,5

Step-by-step explanation:

1 dollar 30 cent = 130 cent

20 copies=130

1 copy=130/20=6,5

The cost of the copy per unit will be $0.065 for each copy.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

If the cost of making 20 copies is $1.30.

Then the cost of each copy is given by the division of $1.30 and 20. Then we rate is given as,

Rate = $1.30 / 20

Rate = $0.065 for each copy

The cost of the copy per unit will be $0.065 for each copy.
