4x + 6y = 18 & 4x – 2y = 10

Answers

Answer 1

Answer:

x=4.875

y=-0.25

Step-by-step explanation:

4x – 2y = 10

2x-y=10

y=2x-10

4x + 6y = 18

2x+3(2x-10)=9

8x=39

x=4.875

y=2(4.875)-10

y=-0.25

Evaluate the function. g(x) = 3x^2 – 2x + 5 Find f(2)​

Answers

Answer:

13

Step-by-step explanation:

Replace X with 2

Evaluate the function. g(x) = 3x^2 – 2x + 5 Find f(2)​

g(x) = 3(2)^2 – 2(2) + 5

Next conduct PEMDAS

Exponents are first so solve 2^2 which is 2 x 2 = 4

g(x) = 3(4) – 2(2) + 5

Next step is multiplication multiply 3 x 4 and 2x2

g(x) = 12 – 4 + 5

conduct adding and subtracting left from right

g(x) = 13

How many times does 3/4 go into 1 1/2

Answers

Answer:

2

Step-by-step explanation:

In order to divide these fractions, you must turn the mixed number into a fraction like below:

1 1/2 = (2 x 1 + 1) / 2 = 3/2

In order to divide fractions, you must multiply by the reciprocal of the denominator. In this case, you are dividing (3/2) / (3/4) and 3/4 is the denominator.

3/2 * 4/3 = 12/6 = 2. Your answer is 2.

Your next Pre-Algebra test is worth 93 points and contains 38 multiple choice and short answer problems. Each
multiple choice problem is worth two points and each short answer is worth three points. How many of each type of
problem is on the test?

Answers

Answer:

21 of multiple choice and 17 of short answer questions

Step-by-step explanation:

Multiple choice = mShort answer = s

Equations:

m + s = 382m + 3s = 93

Solve for s by eliminating m. Subtract the double of the first equation from the second one:

2m + 3s - 2(m + s) = 93 - 2(38)3s - 2s = 93 - 76s = 17

Find the value of m:

m = 38 - 17 = 21

Answer:

10th term of the sequence = 0.537

Step-by-step explanation:

First three terms of the sequence are → 5, 4, [tex]\frac{16}{5}[/tex]..........

Ratio of 2nd and 1st term of the sequence = [tex]\frac{4}{5}[/tex]

Ratio of 3rd and 2nd term of the sequence = [tex]\frac{\frac{16}{5} }{4}[/tex]

                                                                        = [tex]\frac{4}{5}[/tex]

Therefore, ratio between every successive term to the previous term is common.

Common ratio 'r' = [tex]\frac{4}{5}[/tex]

First term of the sequence 'a' = 5

nth term of a geometric sequence = [tex]a(r)^n[/tex]

Therefore, nth term of the given term will be  [tex]T_n=5(\frac{4}{5})^n[/tex]

Now we have to find the 10 term of the given sequence.

For n = 10,

[tex]T_{10}=5(\frac{4}{5})^{10}[/tex]

      = 0.53687

      ≈ 0.537

Therefore, 10th term of the sequence is 0.537
