Answer:

So the solution would be (1,-2). Remember you can always validate that the solution is correct by plugging it into both equations. But this is the same as the first equation, y=3x-5. Since they are the SAME line they will have infinite solutions.

Solve the inequality -5/4(8x+4)<6-3x. Show your work.

Debora [2.8K]

Answer:

$x>-\frac{11}{7}$

Step-by-step explanation:

Step 1: Distribute

$-\frac{5}{4} (8x+4)$

$(-\frac{5}{4} *8x)+(-\frac{5}{4} *4)$

$-\frac{40x}{4}-\frac{20}{4}$

$-10x-5$

Step 2: Add 10x to both sides

$-10x-5\mathbf{+10x}$

$-5$

Step 3: Subtract 6 from both sides

$-5\mathbf{-6}$

$-11$

Step 4: Divide both sides by 7

$-11\mathbf{/7}$

$x>-\frac{11}{7}$

Answer: $x>-\frac{11}{7}$

QUESTION 1 What is the mean of 21, 23, 35, 40)? o A. 27 B. 31.75 e C. 19 D.29.75

tangare [24]

Answer:

D. 29.75

Step-by-step explanation:

To determine the mean, you must add up all the numbers and then divide that number by how many numbers you added.

Here,

21 + 23 + 35 + 40

= 119

You added 4 numbers (21, 23, 35, 40),

so, 119 / 4

= 29.75

Hope this helps and a thank won't hurt! :)

The net of a triangular prism is show below.Find the rotal surface area of the triangular prism 4.6,4,5,15

marysya [2.9K]

Answer:

228.4cm²

Step-by-step explanation:

Find the diagram attached

Total surface area of the prism = Ph + 2B

P is the perimeter of the base (triangle)

h is the height of the prism

B is Base area

P = 5cm + 5cm + 4cm

P = 14cm

h = 15cm

B = 1/2 * base * height

B = 1/2 * 4.6 * 4

B = 4.6 * 2

B = 9.2cm²

Substitute the values into the formula;

Total surface area of the prism = Ph + 2B

Total surface area of the prism = 14(15)+2(9.2)

Total surface area of the prism = 210 + 18.4

Total surface area of the prism = 228.4cm²

Hence the total surface area of the triangular prism is 228.4cm²
