please can you give the answer of this, 8x+5y=23 -8x+9y=-19

Answers

Answer 1
8X+5Y=23
8X=23-5Y

-8X+9Y= -19 multiple all by -1
8X-9Y=19
8x=23-5y
Plug that in
23-5Y-9Y=19
-14Y=19-23
-14Y= -4
Y=1

8X=23-5Y
8X=23-5•1
8X=23-5
8X=18
X=18/8
X=9/4

Determine the vertical asymptotes and holes for the graph of the equation below.

y=[tex]\frac{x+7}{x^2+8x+7}[/tex]

Please show all steps to solve!

Answers

Since x ² + 8x + 7 = (x + 7) (x + 1), we have for x ≠ -7,

y = (x + 7) / (x ² + 8x + 7) = 1/(x + 1)

so y is undefined at x = -1, indicating a vertical asymptote, and there is a hole/removable discontinuity at x = -7. Then the answer is D.

Can a triangle have two obtuse angles? please Justify your answer.

Note that 23% = 23/100 = 0.23

First, multiply $84 with 0.23:

84 x 0.23 = 19.32

Next, subtract 19.32 from the total cost:

84 - 19.32 = 64.68

Answer:

y≤6x+8

Step-by-step explanation:

Given function:

y≤3x+4

This means:

variable stays same

if y=7 then x=1 and if y=14 then x can be 2 or 3.

we can also think as:

y≤6x+8

what we did:

double the number: 3x+4 · 2 = 6x+8

Therefore, another equation for y≤3x+4 would be y≤6x+8.

Annabelle has 56 1 cm³ what are the dimensions of the rectangle Langer prism Annabelle could build with all the cubes

Answers

Answer:

The six possible rectangular prisms Anabelle could build are;

W = 1,  B = 1,  L = 56

W = 1, B = 2,  L = 28

W = 1,  B = 4,  L = 14

W = 2,  B = 2,  L = 14

W  = 1,  B = 7,  L = 8

W = 2,  B = 4,  L = 7

Step-by-step explanation:

The number 1 cm³ Annabelle has = 56

The dimensions volume of the cubes Annabelle could build with the 1 cm³ = 56 cm³

The volume of rectangular prism, V = L × B × W

∴ For the rectangular prism, V = 56 cm³ = L × B × W

Therefore, the possible dimensions of the prism are three factors of 56, including;

1, 2, 4, 7, 8, 14, 28, 56

The combination of 3 factors of 56 that can be multiplied together to give 56 and therefore, the possible rectangular prisms includes;

  W × L × B = A

1) 1 × 1 × 56 = 56

2) 1 × 2 × 28 = 56

3) 1 × 4 × 14 = 56

4) 2 × 2 × 14 = 56

5) 1 × 7 × 8 = 56

6) 2 × 4 × 7 = 56

There are therefore 6 possible rectangular prisms Annabelle could build
