Mathematics

Answer:

y = 4.5 x

Step-by-step explanation:

If this is a proportional relationship, we can find the slope

m = (y2-y1)/(x2-x1)

m = (27-0)/(6-0)

m = 27/6

m=9/2

The slope is 9/2

The y intercept, where it crosses the y axis is 0

Using the slope intercept form of the equation y=mx+b

y = 9/2 x+0

y =9/2x

It wants the decimal form

y = 4.5 x

Answer:

13 cm

Step-by-step explanation:

Use Pythagora's theorem to solve for the hypotenuse of the triangle:

a^2+b^2=c^2

Where a and b are the two shorter legs, and c is the hypotenuse.

Replace the values in and solve for c:

5^2+12^2=c^2\\25+144=c^2\\169=c^2\\13=c

Larry's Lemons is a street vendor business that sells lemonade and lemon bars. A cup of lemonade sells for $2 and a lemon bar se
maxonik [38]

We can let x and y represent cups of lemonade and numbers of lemon bars, respectively. Then the constraints are ...

  • x ≥ 150
  • y ≥ 0
  • 2x +1.5y ≥ 500
  • 0.25x +0.20y ≤ 100

A graph is shown in the attachment, with the ordered pairs plotted. It is not feasible to sell half cups of lemonade or half lemon bars, so the second and third choices must be excluded. The point (160, 110) falls outside the feasible region, so is not a correct choice.

The correct choices are ...

  • (150, 200)
  • (180, 100)

Evaluate the expression when x= -5.2 and y = –6.8.<br> 4x-7y
vfiekz [6]

Step-by-step explanation:

Substitute variables with given values

Minus sign becomes plus sign if a negative is multiplied by a negative or a negative is put next to a negative number.

4x-7y=4(-5.2)-7(-6.8)

-20.8+47.6=26.8
