Answer 1

Answer:

Answer:

D: -2

Step-by-step explanation:

Let's time 2 on both sides.

Then the equation will be:

(3x+4)=x

3x+4=x

-x -x

2x+4=0

-4 -4

2x=-4

x=-2

So the answer is D:-2.

Hoped I helped!

Casey is deciding which of two landscapers to hire. Each landscaper charges an hourly rate plus a fee for each job.Casey correctly wrote and solved a system of linear equations by substitution. In his work, he substituted an expression for one variable and solved for the other. This resulted in the equation 5 = 20. What can Casey conclude?One landscaper charges $20 for 5 hours of work.One landscaper’s hourly rate is $15 lower than the other landscaper’s.Both landscapers charge the same hourly rate and the same fee per job.Both landscapers charge the same hourly rate, but not the same fee per job.

What is the intersection of plane WZVS and plane STUV?

Answers

Answer: The required intersection is the line 'VS'.

Step-by-step explanation: We are given to find the intersection of the planes WZVS and plane STUV.

We know that,

If two planes intersect each other, then their intersection is a straight line.

As shown in the given figure, the point 'V' and 'S' lie on both the planes WZVS and STUV.

So, the line joining these two points, i.e., the line VS also lie on both the planes.

Therefore, the intersection of both the planes is the line 'VS'.

Thus, the required intersection is the line 'VS'.

An easy way to find this is to look at the cross section, and see where the lines meet

Find the product. a 4(3a 2 - 2a + 1)

Answers

Answer:

The product of $a^(4)(3a^(2)-2a+1)$ is $3a^(6)-2a^(5)+a^(4)$ .

Step-by-step explanation:

As given the expression in the question be as follow .

$= a^(4)(3a^(2)-2a+1)$

First open the bracket

$= a^(4)* 3a^(2)-a^(4)* 2a+a^(4)* 1$

Now by using the property of exponent .

$x^(a)* x^(b)= x^(a+b)$

$= 3a^(2+4)-2a^(4+1)+a^(4)$

$= 3a^(6)-2a^(5)+a^(4)$

Therefore the product of $a^(4)(3a^(2)-2a+1)$ is $3a^(6)-2a^(5)+a^(4)$ .

a^4(3a^2 - 2a + 1)

= 3a^6 - 2a^5 + a^4

If x is a number that is 7 more than y, how do you express x as a function of y?

Answers

Hi Mella,

So we basically have:
⇒ x = 7 + y

In order to write this in terms of y, then basically we just have to solve for y. To do this, let's look at the equation again to see how we can get y by itself.

⇒ x = y + 7

If we subtract 7 from both sides, we now have

⇒ x - 7 = y which is the same as y = x - 7.

x is now expressed as a function of y.

-Hope this helps!

I think that it's x=7+y

Tony invested $5,500 in a four-year CD that paid 4.8% interest, but later needed to withdraw $475 early. If the CD’s penalty for early withdrawal was three months’ worth of interest on the amount withdrawn, how much of a penalty did Tony pay

Answers

Given:
principal: 5,500
term: 4 years
interest rate: 4.8% per annum
early wdl of 475

penalty is the 3 months interest of the amount withdrawn.

Interest = 475 * 4.8% * 3/12
Interest = 475 * 1.2%
interest = 5.7 is the amount of the penalty

What is the next term for the given arithmetic sequence? -3, -2.25, -1.5, -0.75, ...-0.25
0
0.75

Answers

Option B is the correct answer.

Step-by-step explanation:

Arithmetic progression have a first term and common difference.

Here first term, a = -3

Common difference, d = -2.25 - (-3) = -2.25 + 3 = 0.75

The n th term of an arithmetic progression is given by a + (n-1) d

Here we need to find fifth term, that is n = 5

Fifth term = a + (n-1) d = -3 + (5-1) x 0.75

Fifth term = a + (n-1) d = -3 + 4 x 0.75

Fifth term = a + (n-1) d = -3 + 3 = 0

So next term for the given arithmetic sequence = 0

Option B is the correct answer.

the next term in the arithmetic sequence is 0 since its adding 0.75 every time.
