miv72 [106K]

Answer:

2x + 4y

$40

Step-by-step explanation:

Equation for x small balloons and y large balloons

2x + 4y

Total cost of 10 small balloons and 5 large balloons

x = 10, y = 5

2(10) + 4(5)

= 20 + 20

= $40

If there are 18 students every one of the will pair up with 17 other students throughout the year so the total amount of pairs that can be made is 18x17=306 but since it’s not important if student A is paired with student B or student B with student A we should divide the total amount of pairs by two- 306:2=153 so in total there will be 153 projects finished

What is an equation of the line that passes through (2,-3) and is perpendicular to y=x-5

Digiron [165]

y = -x - 1 is the equation of the line that passes through (2,-3) and is perpendicular to y = x - 5

Solution:

Given that we have to write the equation of the line that passes through (2,-3) and is perpendicular to y = x - 5

The equation of line in slope intercept form is given as:

y = mx + c ------ eqn 1

Where, "m" is the slope of line and "c" is the y intercept

Given equation of line is:

y = x - 5

On comparing the above equation with eqn 1,

m = 1

We know that,

Product of slope of line and slope of line perpendicular to given line is equal to -1

Therefore,

$1 \times \text{ slope of line perpendicular to given line } = -1\\$

Slope of line perpendicular to given line = -1

Now we have to find the equation of line with slope -1 and passing through (2, -3)

Substitute m = -1 and (x, y) = (2, -3) in eqn 1

-3 = -1(2) + c

-3 = -2 + c

c = -3 + 2

c = -1

Substitute m = -1 and c = - 1 in eqn 1

y = -x - 1

Thus the equation of line is found
