Since you cannot add numbers which have x to the power of something and normal x, A and B are incorrect. C is also incorrect because I don't even know how you could get that number.
D is correct.
(14x2 + 7x) + 9x2 - you don't even need the brackets, so
14x2 + 7x + 9x2 
(14x2 + 9x2) + 7x
23x2 + 7x

<h3>Answer:</h3>

4) ÷10

5) Yes

<h3>Step-by-step explanation:</h3>

<em>Question 4</em><em>:</em>

Just take the first number 322 and plug in the choices.

At the end the only one that will finish with all exactly like the pattern is ÷10.

<em>Question</em><em> </em><em>5</em><em>:</em>

We know Logan's watch is still under warranty because,

1 week = 7 days.

6 weeks × 7 days = 42 days

But he has 90 days, so there is still more than 50 days that he can go return it and will get his money back.

<h3>Hope this Helps!!</h3>

Put these points into an equation IN STANDARD FORM!!!!!!<br><br>(0,2) and (8,0)
zubka84 [21]

The equation of the line in standard form is x + 4y = 8

<h3>How to determine the line equation?</h3>

From the question, the points are given as

(0, 2) and (8, 0)

To start with, we must calculate the slope of the line

This is calculated using

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (0, 2) and (8, 0)

Substitute the known parameters in Slope = (y₂ - y₁)/(x₂ - x₁)

So, we have

Slope = (0 - 2)/(8 - 0)

Evaluate

Slope = -1/4

The equation of the line can be calculated using as

y - y₁ = m(x + x₁)

Where

(x₁, y₁) = (0, 2)

and

m = slope = -1/4

Substitute the known values in the above equation

So, we have the following equation

y - 2 = -1/4(x - 0)

This gives

y - 2 = -1/4x

Rewrite as

1/4x + y = 2

Multiply by 4

x + 4y = 8

Hence, the line has an equation of x + 4y = 8
