Solve the system of equations by adding. checking your answer

Mathematics
1 answer:
Brut [27]3 years ago
3 0

Answer:

Step-by-step explanation:

This is very easy, because the coefficients of the y terms are 2 and -2. You can easily eliminate the y terms by adding the equations together:

2x + 2y = 2

3x - 2y = 43

-----------------

5x + 0y = 45,  so x = 9

Use the value of x to solve for  y:

2(9) + 2y = 2

y = -8

(x,y) = (2, -8)

The lengths of salamanders have a normal distribution with mean 15cm, and standard deviation 2cm. What length of salamander woul
Law Incorporation [45]

Answer:

16.68 cm

Step-by-step explanation:

Given that :

Mean , m = 15

Standard deviation, s = 2

Length of salamander that would Place it at 80% of salamander length :

P(Z ≤ x) = 0.8

Zscore equivalent to 0.8 = 0.842

Using the relation :

Zscore = (x - m) /s

0.842 = (x - 15) / 2

1.684 = x - 15

Add 15 to both sides

1.684 + 15 = x - 15 + 15

16.684 = x

Hence, x = 16.68 cm

RSTUV - EABCD. Find AE.
larisa86 [58]

9514 1404 393

Answer:

  AE = 3

Step-by-step explanation:

First of all, we need to find corresponding sides that are defined in both figures. The table below shows the given values.

From the table, we can write the proportion ...

  EA/RS = BC/TU . . . corresponding sides are proportional

  EA/6 = 4/8 . . . . . . . substitute given lengths

  EA = 6(4/8) = 3

The length of AE is 3 units.
