y = -4x + 3
8x + 2y = 8
Solve by using elimination.

Answers

Answer 1

Answer:

The equations are not compatible

Step-by-step explanation:

y = -4x + 3

8x + 2y = 8

substitute for y:

8x + 2(-4x + 3) = 8

simplify:

8x - 8x + 6 = 8

6 ≠ 8

There are 4 consecutive integers that have sum of 266 . Which integers are they?

Answers

Answer:

the four consecutive integers are 65 , 66 , 67 and 68 .

Step-by-step explanation:

you should let the first integer be x

so that would leave the 2nd as x + 1

The 3rd would be x + 2

and the 4rth would be x + 3

so X + X + 1 + X + 2 + X +3 =266

you can combine your like terms:

X+X+X+X= 4x

and 1+2+3=6

then you do simple algebra:

4x= 266-6

266-6= 260

4x=260

divide both sides by 4

260/4 is 65

x = 65

65 is your answer then you go up by 3 numbers.

Answers

Answer:

(-2, 1).

Step-by-step explanation:

Move (-3, -1) one unit to the right, and you get (-2, -1). Reflect (-2, -1) over the y-axis, and the coordinates will be (-2, 1).

The only thing that changes is the y coordinate. If you had reflected it over the x-axis, the x coordinate would have changed and the y coordinate would have stayed the same.

Melody Pond and a tree cast a shadow at the same time of day. Melody is 5.6 feet tall and casts a 10-foot shadow. If the length of the tree's shadow is 62 feet, what is the height of the tree?

Answers

Answer:

34.72 feets

Step-by-step explanation:

Using the relation :

Length of tree / shadow of tree = height of melody / shadow of melody

From the details given in the question :

Let height of tree = h

h / 62 = 5.6 / 10

Cross multiply

h * 10 = 62 * 5.6

h = 347.2 / 10

h = 34.72 feets

Hence, the height of tree is 34.72 feets

Answers

Answer:

1 9/10 kilometers

Distance 1 = 3/5 kilometers

Distance 2 = 1/2 kilometers

Total distance to be covered = 3 kilómeters

Distance already covered :

3/5 + 1/2

(6 + 5) / 10

= 11 / 10 kilometers

Distance left to be covered :

3 - 11/ 10

(30 - 11) / 10

= 19 / 10 kilometers

= 1 9/10 kilometers

. For what value of x do the expressions 2x +2 and 3x – 6 have the same value?

Answers

Answer:

x = 8

Step-by-step explanation:

To find the solution, equate the 2 expressions, that is

3x - 6 = 2x + 2 ( subtract 2x from both sides )

x - 6 = 2 ( add 6 to both sides )

x = 8

As a check

2x + 2 = 2(8) + 2 = 16 + 2 = 18

3x - 6 = 3(8) - 6 = 24 - 6 = 18

Both expressions have the same value when x = 8
