Answer:

See below

Step-by-step explanation:

y = 2x + 4     Substitute this for y in the second equation

6x - 3y = -12

6x - 3(2x + 4) = - 12  Substitute this for y for 2x + 4

6x - 3(2x) -3(4) = -  12    Distributive property

6x - 6x - 12 =  - 12

(6x - 6x) -12 = - 12   like terms together

 0 - 12 = - 12       Simplify

-12 = -12        True equation so x is equal to any number  and you have the same equation

Answer:

1. Scatter plots are used to observe relationships between variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point.

2. A Scatter Analysis is used when you need to compare two data sets against each other to see if there is a relationship. Scatter plots are a way of visualizing the relationship; by plotting the data points you get a scattering of points on a graph

Write the explicit formula for the geometric sequence.
My name is Ann [436]

Answer:

D

Step-by-step explanation:

the n th term ( explicit formula ) of a geometric sequence is

• a_{n} = a_{1}(r)^{n-1}

where r is the common ratio and a_{1} the first term

here r = \frac{8}{16} = \frac{16}{32} = \frac{1}{2} and a_{1} = 64, hence

a_{n} = 64(0.5)^{n-1} → D
