Substitute.
2x+(2x -15) = -3

4x -15 = -3
Add 15 to both sides

4x = 12

Divide by 4

X=3

2(3) + y = -3

6+y=-3
-6 from both sides
Y=-9

(3,-9)

aleksley [76]

Answer:

Standard error for the distribution of means = 0.4474

Step-by-step explanation:

Standard error for the distribution of means is given as

σₓ = σ/√n

where σ = standard deviation = 2.237

n = sample size = 25

σₓ = (2.237/√25)

σₓ = 0.4474

Hope this Helps!!!

Add. Simplify the answer to lowest terms before entering the numerator and denominator in their boxes. 11/16 + 3/16
myrzilka [38]

Answer:

The answer is 7/8.

Step-by-step explanation:

If you add 11/16 to 3/16, you'll get 14/16.  14/16 has two numbers that are divisible by 2,  so when you divide 14/16 by 2 you'll get 7/8 which is 14/16 in a simplified form.  7 is prime and you can't divide it down any more, but 8 i'snt the same way.  The rule is, whatever you do to one side, you have to do to the other.  You can divide 8, but not 7; therefore, you cannot simplify the fraction any further.
