Please help me with this ​
MissTica

Answer:

For the question on the right, I assume b is the exponential factor, or growth factor.

Step-by-step explanation:

Linear:

Y=aX + b\\(X, Y) = (0, 15) => b = 15\\(X,Y) = (1, 12) => a = -3\\Y = -3X + 15

You can find the equation by using two points and the equation for a line.

Exponential:

Y = a^{bX+c}\\(X, Y) = (0, 81) => a^{c} = 81 => a^{c} = 3^{4} => a=3, c=4\\(X, Y) = (1, 27) => a^{b+c} = 27 => a^{b}a^{c} = 27 => a^{b} = \frac{27}{81} = \frac{1}{3} => b=-1\\Y = 3^{-X+4}

Please help! I dont understand math at all! :o(
Brut [27]

Answer:

$393.75

$2,446.88

Step-by-step explanation:

Let's take this problem one step at a time. First let's compute for the total price after the sales tax has been added.

Sales tax = 8.75% or 0.0875

Original Price = $4,500

The sales tax is computed by multiplying the total to the sales tax rate.

4,500 x 0.0875 = $393.75

$393.75 is the total sales tax that Brenton will pay.

Now to find the total price with the sales tax included, we simply add the original price and the sales tax value together.

4,500 + 393.75 = $4,893.75

Now that we have the total overall price, we can then compute for how much the 50% down payment Brenton has made.

Down Payment = 50% or 0.5

Overall Price = $4,893.75

We simply multiply both the down payment and the overall price to find how much Brenton has paid.

4,893.75 x 0.5 = $2,446.88

Now that we know how much Brenton paid, we also now know how much Brenton financed by subtracting the overall price to his down payment.

4,893.75 - 2,446.88 = $2,446.88

Brenton finance a total amount of $2,446.88.

Bobby has already ran 1 mile on his own, and he expects to run 1 mile during each track practice. How many track practices would
german

Answer:

In order to have ran 33 miles, Bobby would have to attend <em>32 track practices.</em>

Step-by-step explanation:

Solving this problem entails of uncovering the amount of track practices Bobby must attend in order to have ran 33 miles. Start by reading the problem carefully to break down the information provided.

You can see that Bobby has already ran one mile on his own. This is important to remember for later. The problem also states that he expects to run one mile at every track practice.

Setting up an equation will help us solve. Here is how we could set up the equation:

(<em>amount of miles already ran</em> = 1) + (<em>number of track practices</em> = x) = (<em>total miles to run</em> = 33)

1 + x = 33

The equation is now in place. You can solve this, or isolate <em>'x',</em> by using the subtraction property of equality. This means we will subtract one from both sides of the equation, thus isolating the variable.

1 + x = 33

1 - 1 + x = 33 - 1

x = 32

The variable is the only term left on the left side of the equation. This means Bobby must attend track practice <em>32 times</em> in order to have ran 33 miles.

Plz help urgent so easy will give brainliest mark for the first answer given!!
timama [110]

Answer:

Step-by-step explanation:

6). Equation of the line has been given as,

    4x + 9y = -9

    By converting this equation into y-intercept form,

    9y = -4x - 9

    y=-\frac{4}{9}x-\frac{9}{9}

    y=-\frac{4}{9}x-1

    By comparing this equation with y = mx + b

    Here, m = Slope of the line

    b = y-intercept

    Slope of the equation (m) = -\frac{4}{9}

    y-intercept (b) = -1

8). Equation of the line is,

    5x + 3y = 12

    3y = -5x + 12

    y=-\frac{5}{3}x+\frac{12}{3}

    y=-\frac{5}{3}x+4

    Slope of the line = -\frac{5}{3}

    y-intercept = 4
