Answer:

Explanation:

<u><em>y = 2x + 2</em></u>

<u><em /></u>

x: -4

y = 2(-4) + 2

y = -6

x: -3

y = 2(-3) + 2

y = -4

x: -2

y = 2(-2) + 2

y = -2

x: -1

y = 2(-1) + 2

y = 0

x: 0

y = 2(0) + 2

y = 2

x = 1

y = 2(1) + 2

y = 4

x = 2

y = 2(2) + 2

y = 6

write a system of linear equations that has only one solution. solve the system of equations in two ways.

Iteru [2.4K]

X + 5y = 1 . . . . (1)
8x - 2y = 3 . . . .(2)
Solution 1.
From (1), x = 1 - 5y
substituting for x in (2), we have:
8(1 - 5y) - 2y = 3
8 - 40y - 2y = 3
8 - 42y = 3
42y = 5
y = 5/42
x = 1 - 5(5/42) = 1 - 25/42 = 17/42.

Solution 2.
Multiply (1) by 8, to get:
8x + 40y = 8 . . . . . (3)
(3) - (2) = 40y - (-2y) = 8 - 3
42y = 5
y = 5/42
substitute for y into (3), to get:
8x + 40(5/42) = 8
8x + 100/21 = 8
8x = 8 - 100/21 = 68/21
x = (68/21)/8 = 17/42

Hfuuf help me plsssss

denpristay [2]

Answer:

a) 26

b) 26/3

Step-by-step explanation:

1) First, you have to turn 4 1/3 into an improper fraction, so you get 13/3

2) Then you do 13/3 *6/1 =78/3 (so you multiply both numerators and denominators)

3) Lastly, 78/3 can be simplified as 26

1) First you turn both fractions into improper fractions, so you get 13/5 and 10/3

2) Then you do 13/5*10/3 (so you multiply both numerators and denominators)

3) You get 130/15, which can be simplified as 26/3

Lelu [443]

Answer:

Hence the expression $(x+8)(x+3)=x^{2}+11 x+24$ .

Step-by-step explanation:

- The given expression is (x+8)(x+3).

- We have to multiply the given expression.

- Multiply the (x+8) by 3 , multiply the (x+8) by x then add like terms.

$\begin{array}{r}x+8 \\\underline {\times \quad x+3} \\3 x+24 \\\underline {x^{2}+8 x+24} \\x^{2}+11 x+24\end{array}$
