Answer:

B. x = −1

Step-by-step explanation:

In the graph, the vertex of the parabola hits point (-1,-2). Therefore, the axis of symmetry is x = -1. It is not y = -2, since the parabola opens vertically, not horizontally.

A family buys a studio apartment for $180.00 They pay a down payment of $54.00, Their down payment is what percent of the purcha
Volgvan

Answer:

Part A: 30%

Part B: 45000%

Step-by-step explanation:

To get your answer, you have to divide whatever number the down payment is by the number the family is supposed to pay for the studio apartment.

Part A: You need to divide $54.00 by $180.00, when you do that, you get the answer 0.3. You convert it to percentage by doing 0.3 multiplied by 100 which give you 30. Put a percent behind it and you have 30% as your final answer.

Part B: You need to divide 81,000 by 180 which gives you 450. Then you then have to do 450 multiplied by 100 which gives you 45,000. You then add the percentage behind and you have 45000% as your final answer.

Find the equation of a line that contains the points (3,7) and (-6, 4). Write the equation in slope-intercept form, using
NikAS [45]

Answer:

y=\frac{1}{3} x+6

Step-by-step explanation:

(3,7)(-6,4)

Step 1. Find the slope (by using the slope-formula)

m = slope

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{4-7}{-6-3}

m=\frac{-3}{-9}

m=\frac{3}{9}

m=\frac{1}{3}

Step 2. Write the equation (using the slope and the points)

Here's how to do it:

Slope-intercept Formula y=mx+b whrere m = slope and b = y-intercept

Plug in the slope into the Slope-intercept Formula

y=\frac{1}{3} x+b

Find the y-intercept (b) by using a point and substituting their x and y values

y=\frac{1}{3} x+b

Point: (3, 7)

7=\frac{1}{3} (3)+b

7=1+b

b=7-1

b=6

Step 3. Write the equation in Slope-intercept form

y=mx+b

y=\frac{1}{3} x+6
