asambeis [7]3 years ago
4 0

Answer:

-2x2a • (2x2 + 4b - 5)

Step-by-step explanation:

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 2xa • ((-4xb -  2x3) +  5x)

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -2x3 - 4xb + 5x  =   -x • (2x2 + 4b - 5)  

Trying to factor a multi variable polynomial :

3.2    Factoring    2x2 + 4b - 5  

Try to factor this multi-variable trinomial using trial and error  

Factorization fails

Multiplying exponential expressions :

3.3    x1 multiplied by x1 = x(1 + 1) = x2

Final result :

 -2x2a • (2x2 + 4b - 5)

Select the correct graph of the equation.
tatyana61 [14]

Answer:

A

Step-by-step explanation:

The -2 indicates that y would be -2; because A is the only option with that being true, we can eliminate all other potential options rather quickly.

I believe this is 3/5x-2 but please take pictures with all information in view so we can provide better answers!

Tasha invests $5000 annually at 6% and an additional $5000 annually at 8%. Thomas invests $10000 annually at 7%. Which statement
REY [17]

Answer:

Answer:

Option B is correct.

Step-by-step explanation:

We will compare the interest earned by both.

Tasha: p = $5000

r = 6% or 0.06

n = 1

So, Amount after a year will be = = $5300

And amount the next year with p = 5300: 5300*1.06= $5618

Additional $5000 at 8%

Here the amount will be = =5400

Next year amount with p = 5400 : 5400*1.08 = $ 5832

Amount in total Tasha will have in 2 years = 5618+5832 = 11450

Thomas:

p = 10000

r = 7% or 0.07

n = 1

After a year the amount will be = =$10700

Amount Next year with p = 10700 : 10700*1.07 = $11449

*****Just after 1 year we can see that Tasha's total amount is high than Thomas. This means at the same consistent rate, each year Tasha's amount will always be higher than Thomas.

So, option B is correct. Tasha’s investment will yield more over many years because the amount invested at 8% causes the overall total to increase faster.

Someone help me please !!!
KIM [24]

Answer:

1. 10

2. 12

3. Sqrt 130

4. Sqrt 45

Step-by-step explanation:

To find the missing side of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem is a^2+b^2=c^2 where a and b are the legs with a being the smallest and c is the hypotenuse.

1. a=6, b=8, c=?

6^2+8^2=c^2\\36+64=c^2\\100=c^2\\10=c

2. a=5, b=?, c=13

5^2+b^2=13^2\\25+b^2=169\\169-25=b^2\\144=b^2\\12=b

3. a=7, b=9, c=?

7^2+9^2=c^2\\49+81=c^2\\130=c^2\\\sqrt{130}=c

4. a=2, b=?, c=7

2^2+b^2=7^2\\4+b^2=49\\49-4=b^2\\45=b^2\\\sqrt{45}=b
