5) 4x – 5y = -20<br> What is the slope
EastWind [94]

Answer: 4/5

Step-by-step explanation:

To find the slope, solve for y

4x - 5y = -20

-5y = -4x - 20

y = \frac{4x}{5} +4

The slope is the coefficient of x which is \frac{4}{5}

What is the distance between the points (25 , 12) and (9 , 12) in the coordinate plane? A. 8 units B. 34 units C. 16 units D. 13
TEA [102]

Answer:

The answer to the question provided is 16 units.

.

Step-by-step explanation:

☆Well, we simply use the distance formula, which is:

d =  \sqrt{(x_2 - x_1)^{2}  + (y_2 - y_1)^{2} }

...

☆All we need to do is plug in!

d =  \sqrt{(x_2 - x_1)^{2}  + (y_2 - y_1)^{2} } \\ \\  d =  \sqrt{(9 - 25) {}^{2}   +  (12 - 12)^{2} }  \\ d =  \sqrt{( - 16)^{2} + (0) ^{2}  }  \\  d =  \sqrt{256 + 0}  \\ d =  \sqrt{ 256 }  \\ d = 16

What is the value of the expression when x = 4?<br> 8x^2 + 3x
tamaranim1 [39]

Answer:

The value of the expression at x = 4 is 140

Step-by-step explanation:

<em>Let us solve the question</em>

∵ The expression is 8x² + 3x

∵ x = 4

→ To find the value of the expression at x = 4 substitute x by 4 in

    the expression, then calculate the value of it

∵ The value of the expression = 8(4)² + 3(4)

→ Solve the power first

∴ The value of the expression = 8(16) + 3(4)

→ Simplify each term using multiplication

∴ The value of the expression = 128 + 12

→ Add the terms

∴ The value of the expression = 140

∴ The value of the expression at x = 4 is 140

dmitriy555 [2]

Answer:P(t) = 10t - 400

Step-by-step explanation:

Selling price of each ticket = $10

Cost of setting up the dance= $400

Profit = Revenue - cost

Revenue = price × quantity

Revenue that will maximize profit = 10t  

where t= quantity of tickets that maximises profits

Cost = $400

Profit(t) = Revenue - cost

P(t)= 10t - 40
