Answer:

<em>Another point on the graph is (0;0).</em>

Step-by-step explanation:

To find another point on the graph, we have to find the equations of the line.

In first place, we need to calculate the slope, which definition is:

m=\frac{x_{2}-x_{1}}{y_{2}-y_{1}}

The problem gives us the two points needed to find the slope:

m=\frac{x_{2}-x_{1}}{y_{2}-y_{1}}\\m=\frac{315-105}{3-1}=\frac{210}{2}=105

Now, we use the slope and one point to find the equation with the point-slope formula:

y-y_{1}=m(x-x_{1})\\y-105=105(x-1)\\y=105x-105+105\\y=105x

The independent term is missing, this means that it's zero. So, when a linear function doesn't have the independent terms, we know that the line will pass through the origin of the system, which is (0;0)

Therefore, another point on the graph is (0;0)

(The graph is attached. The slope is two high, that's why the line is almost vertical).

Jully bought 3 slices of cheese pizza and 4 slices of pepperoni pizza for $18.00. Christian bought 3 slices of cheese pizza and
andrew11 [14]

Answer:

$2.00

Step-by-step explanation:

You can form an equation with these statements, x being the price of cheese pizza and y being the price of pepperoni. Making the equation,

3x+4y=18

3x+2y=12

Solving the equation,

3x+4y=18

6x+4y=24

-3x=-6

x=2

y=3

Solving another way,

2y=6

y=3

x=2

Therefore, the answer is $2.00

When number can each term of the equation be multiplied by to eliminate the fractions before solving 6-3/4x+1/3=1/2x+5​
PolarNik [594]

Answer:

12

Step-by-step explanation:

You need to find the least common denominator (LCD) to all the denominators of the fractions present in the equation. These denominators are (writing them in their prime factor form to make our calculations easier):

4=2^2\\3=3\\2=2

Therefore, we need to include a factor of 3, and two factors of 2 (2^2) in our least common denominator, so this LCD will be a perfectly divided by all three given denominators, therefore eliminating all fractions in the equation.

Our LCD is = 3*2^2=13*4=12

A paper sheet is cut 28 inches to the nearest inches. Find the maximum and minimum length of the patient possible.
aliina [53]

Answer:

  • max: 28.5 inches
  • min: 27.5 inches

Step-by-step explanation:

If the actual dimension were different from 28 inches by more than 1/2 inch, it would be reported as a different dimension. So, the minimum that will be reported as 28 is 27.5. The maximum that will be reported as 28 will be 28.4999999.... ≈ 28.5

The maximum and minimum length of the sheet are 28.5 inches and 27.5 inches, respectively.
