Answer 1
Answer:

The scatter plot which shows the weakestpositive linear association is; On a graph, points are grouped closely together and increase.

Which scatterplot shows the weakest positive linear association?

It follows from the task content that the scatterplot which shows the weakest positive linear association be identified.

On this note, for an association to be positive, the graph must increase. However, the scenario described is a weak linear association, hence, the points don't necessarily form a line accurately, they just have to be closely together and increase.

Name the slope and one point that is on the linerepresented by the equation: x = -2
A) m = undefined and point (-2,5)
B) m = 0 and point (-2,4)
C) m = undefined and point (5,-2)
D) = zero and point (5,0)

Answers

Answer: Choice A

m = undefined

point (-2,5)

==================================================

Explanation:

The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)

Another point on this line is (-2,5) since this also has x coordinate -2.

------------------

All vertical lines have undefined slope.

Let's pick two points such as (-2,0) and (-2,1) and find the slope through them

m = (y2-y1)/(x2-x1)

m = (1-0)/(-2-(-2))

m = (1-0)/(-2+2)

m = 1/0

m = undefined, since we cannot divide by zero.

After writing a $800 check to pay a bill, a student had a balance of $350 in his account. How muchdid he have in the account before he wrote the check?
a) Let X = his balance before writing the check. Write the equation you would use to solve this
problem.

Answers

The equation to solve the problem is X  - $800 = $350. And the amount in his account before he wrote the check is $1150.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that after writing an $800 check to pay a bill, a student had a balance of $350in his account.

We need to find out how much did he have in the account before he wrote the check.

The amount of the check = $800

The amount the student has in balance = $350

The amount the student had before he wrote the check.

Let X be the amount the student had before the check.

Now,

X  - $800 = $350

X - 800 = 350 is our equation to find the amount the student has before the check.

The value of X can be written as,

We have,

X  - $800 = $350

Add $800 on both sides

X = $350 + $800

X = $1150

Hence, the equation to solve the problem is X  - $800 = $350. And the amount in his account before he wrote the check is $1150

X2 + 17x − 12 = −84

Answers

Answer:

Step-by-step explanation:

The given quadratic equation is expressed as

x^2 + 17x − 12 = −84

Adding -84 to the left hand side and the right hand side of the equation, it becomes

x^2 + 17x − 12 + 84 = −84 + 84.

x^2 + 17x + 72 = 0

We would find two numbers such that their sum or difference is 17x and their product is 72x^2. The two numbers are 8x and 9x. Therefore

x^2 + 8x + 9x + 72 = 0

x( x + 8) + 9(x + 8) = 0

x + 9 = 0 or x + 8 = 0

x - 9 or x = 8
