Answer:

a) 186

Step-by-step explanation:

g(x) = 7(x^2 + 3) - 10

g(5) = 7((5)^2 + 3) - 10

g(5) = 7(25 + 3) - 10

g(5) = 7 × 25 + 7 × 3 - 10

g(5) = 175 + 21 - 10

g(5) = 186

Match each graph with the correct slope of the line. drag and drop the answer
OLEGan [10]

Answer/Step-by-step explanation:

✔️Slope of the first graph:

Using two points on the line, (0, 1) and (3, 2),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{3 - 0} = \frac{1}{3}

Slope = ⅓

✔️Slope of the second graph:

Using two points on the line, (0, 0) and (1, 1),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 0}{1 - 0} = \frac{1}{1} = 1

Slope = 1

✔️Slope of the third graph:

Using two points on the line, (0, 1) and (2, 2),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{2 - 0} = \frac{1}{2}

Slope = ½

Sophia manages a landfill. She decides to measure the rate at which trash increases in volume to fill the landfill as the number
goblinko [34]

Answer:

\frac{m^3}{h}, \frac{cm^3}{h},  \frac{km^3}{h}

Step-by-step explanation:

If you look at the objects thrown as garbage, it's a two- or three-dimensional item that takes up space and also has mass and this is a solid waste.

And the landfill that dumps such garbage is also three-dimensional.

Hence, the volume module, if the object inside is a solid, either would be

m^3,cm^4,Km^3

As household numbers rise, landfill space increases.

So,

household\ number = Proportionality\times  landfill\ space

If H represents the number of household keeps,  then it will be a sufficient unit for the purpose of Sophia that is

\frac{m^3}{h}, \frac{cm^3}{h},  \frac{km^3}{h}

How do you write 12,430,000 in expanded form
const2013 [10]

we know that

12,430,000 in expanded form is equal to

12,430,000=1*(10,000,000)+2*(1,000,000)+4*(100,000)+3*(10,000)\\\\   12,430,000=(10,000,000)+(2,000,000)+(400,000)+(30,000)

therefore

<u>the answer is</u>

(10,000,000)+(2,000,000)+(400,000)+(30,000)

Anna has a total of 36 goldfish in her aquarium, some are orange and some are black. The number of orange goldfish is 7 more tha
andriy [413]

Answer:

x + y = 36.....Equation 1

x = 7 + 2y...... Equation 2

Step-by-step explanation:

Let the number of:

Orange goldfish = x

Black gold fish = y

Anna has a total of 36 goldfish in her aquarium, some are orange and some are black.

x + y = 36.....Equation 1

The number of orange goldfish is 7 more than twice the number of black goldfish.

x = 7 + 2y...... Equation 2

We can rewrite this as:

x - 2y = 7..... Equation 2

The system of equations below that can be used to describe the number of black and orange goldfish in Anna's aquarium is :

x + y = 36.....Equation 1

x = 7 + 2y...... Equation 2
