Answer:

X = 7

AB = 14

BC = 14

CA = 14

Step-by-step explanation:

This is an equilateral triangle so you can set the lengths equal to each other in order to find X.

2x=x+7

-x -x

x=7

you can do this with any combination of the lengths and you will always get 7

Now you plug in 7 for x

Original: 2x

Plug in 7: 2*7

You get 14

Since this is after all, an equilateral triangle all lengths are equal so all lengths are 14.

Given the vertex of (3, 6) of a quadratic and a point at (4,8) what would be the a value for the quadratic?

svetoff [14.1K]

Answer:

a = 2

Step-by-step explanation:

The vertex form y = a(x - h)^2 + k

Where (h, k) is the vertex.

Given: (h, k) = (3, 6) and point (4, 8)

Now plug in the given values and find the value of "a"

x =4 and y = 8

8 = a(4 - 3)^2 + 6

8 = a(1)^2 + 6

8 = a + 6

a = 8 - 6

a = 2

So the value of a = 2.

Hope you will understand the concept.

Thank you.

Sonya plans to spend at least 15$ on berries to make pies. Strawberries are on sale for 3$ per pint, and blueberries are on sale

bekas [8.4K]

Answer:

15 ≥ 3x + y

8 ≥ x + y

Step-by-step explanation:

Strawberries= 3x

Blueberries= y

At least symbol= ≥

15 ≥ 3x + y (Plans to spend AT LEAST $15 so this has to be 15 ≥)

8 ≥ x + y (Plans to spend AT LEAST 8 pints so this has to be 8 ≥)

The number of points Marcus scored in different rounds of a computer board game is shown

shtirl [24]

Answer:

583

Step-by-step explanation:

The mean of a data set is the average of the data set. It can be found by adding up all of the values and then dividing by the total number of values added. In this case, one is given the mean, and one needs to find a missing value. Since there is a missing element, add one to the total number of values in the data set. The missing element is represented by the parameter (x). Set up an equation and solve:

$\frac{(236)+(342)+(328)+(352)+(352)+(306)+(317)+(x)}{8}=325\\$

Simplify,

$\frac{2233+x}{8}=352$

Inverse operations,

$2233+x=2816\\\\x = 583$
