Mathematics
1 answer:
Tcecarenko [31]2 years ago
8 0
First things first, write out your equation without the substitution.

2x+ 2y= 10

Now, put in the substitution.

2x+ 2• 2= 10

Combine like terms.

2x+ 4= 10

Now that your equation it simplified, you need to reverse the problem and put everything on the other side.

2x+ 4= 10
- 4 - 4
2x = 6

2x=6
— —
2 2

X= 3

So the final answer is x=3

The length of a rectangle is 1/4 of the width the perimeter is 10 inches what is the width?
natita [175]

Answer: 4

Step-by-step explanation: 1/4w + 1/4w + w + w = 10

                                              2/4w + 2w = 10

                                              1/2w + 2w = 10

                                               2.5w = 10

                                               Divide 10 by 2.5

                                              width = 4

The heights of adult men in america are normally distributed, with a mean of 69.1 inches and standard deviation of 2.65 inches.
Nesterboy [21]
The solution for this problem is:It's given that the heights are normally distributed. 
5 feet 7 inches = (5*12 +7) inches = (60+7) inches = 67 inches. 
The z-score is (67 - 69.1)/(2.65) = -1.136. The probability is 0.127978 or 12.8%, making probability of a height over 67 inches

The graph of a quadratic function meets the x axis where the x=3 and x=k. if the turning point of the function occurs where x=0.
liraira [26]

Step-by-step explanation:

The turning point of a quadratic function is equidistant from both x-intercepts (if they exist)

Since they do exist in this question, 3 + k = 2(0.5), 3 + k = 1, k = -2.
