Answer:

Therefore,  |5 – 3x| = –8  has no solution.

Step-by-step explanation:

Given  :  |–x – 3| = 5

              |2x – 1| = 0

              |5 – 3x| = –8

              |–x + 9| = 0.

To find  : Which equation has no solution.

Solution : We have given that |–x – 3| = 5

                                                  |2x – 1| = 0

                                                  |5 – 3x| = –8

                                                   |–x + 9| = 0

As we know that values outside the modulus is positive or zero.

Then, all the option has positive values or zero except  |5 – 3x| = –8 .

If we plug any values of x it would not be equal to -8 .

Therefore,  |5 – 3x| = –8  has no solution.

Answer:

Option B. 75

Step-by-step explanation:

we know that

<u>A negative correlation</u> or inverse correlation is a relationship between two variables such that as the value of one variable increases, the other decreases

we know that

For L1=150, K1=7

so

For K2=14, L2=?

we have that

L1*K1=L2*k2

substitute the values

150*7=L2*14

L2=150*7/14

L2=75

An investor invested a total of $2,800 in two mutual funds. One fund earned 5% profit while the other earned 3% profit. If the i
Natasha_Volkova [10]

Answer:

The amount invested in the mutual fund that earned 5% was $1,000

The amount invested in the mutual fund that earned 3% was $1,800

Step-by-step explanation:

Let

x ----> the amount invested in the mutual fund that earned 5%

y ----> the amount invested in the mutual fund that earned 3%

we know that

x+y=2,800 ----> y=2,800-x ----> equation A

5\%=5/100=0.05

3\%=3/100=0.03

0.05x+0.03y=104 ----> equation B

Solve the system by substitution

substitute equation A in equation B

0.05x+0.03(2,800-x)=104

Solve for x

0.05x+84-0.03x=104

0.05x-0.03x=104-84

0.02x=20

x=\$1,000

<em>Find the value of y</em>

y=2,800-x

y=2,800-1,000=\$1,800

therefore

The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800

I can answer 18 for you, but I don't understand 16

18. Since when we lose 3 girls the ratio for the girls side drops by 1, that tells us that 1 digit equals 3 people.

a) 5*3=15 so our answer is 15 girls.

b) 4*3=12 and 5*3=15 so 15+12, our answer would be 27
