Two straight lines perpendicular to each other, the slope of which is negative reciprocal.

y=-4/3x+b

The known points are put into the linear equation

y=-4+b

b=13

y=-4/3x+13

First, put the equation of the line given into slope-intercept form by solving for y. You get y = 2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.

makvit [3.9K]

Given :

High Construction Company distributed 8% of its total profit, an amount equal to $5500 in  bonus this year.

To Find :

The total profit .

Solution :

Let , total profit be x .

It is given that 8 % of the total profit is equal to $5500 .

So ,

\dfrac{8x}{100}=5500\\\\x=\dfrac{5500\times 100}{8}\\\\x=\$\ 68750

Therefore , total profit is $68750 .

Hence , this is the required solution .

Do this problem for me? 1st correct answer gets a brainliest...
Fantom [35]

The expression x > -4 means "all the numbers stricktly greater than -4"

Since the number line is oriented with positive direction going to the right, a number is greater than another if its sits to its right.

So, we want all the numbers to the right of -4, excluded -4 itself.

So, the answer is D.

The graph below shows the total cost for lunch, c, when Will and his friends buy a large salad to share and several slices of pi
melamori03 [73]

Answer:

The correct option is <u>$2.50</u>.

Step-by-step explanation:

This can be determined by calculating the change in total cost of lunch using the data given in the question as follows:

Slice of pizza     Total cost of lunch ($)    Change in total cost of lunch ($)

         0                                7.5                                          -

         1                                 10                                          2.5

         2                                12.5                                       2.5

         3                                 15                                          2.5

         4                                 17.5                                       2.5

         5                                 20                                         2.5

         6                                 22.5                                      2.5

         7                                 25                                         2.5

         8                                 27.5                                      2.5

Since the change in total cost of lunch in table abov is constant at $2.50, this implies that for each additional slice of pizza that is purchased, the total cost of lunch increases by $2.50.

Therefore, the correct option is <u>$2.50</u>.
