What is y=-4x-4 in standard form
Answer: 4x + y = -4
Step-by-step explanation:
The standard form of a linear equation is Ax + By = C.
y = -4x - 4
Add 4x on both sides
4x + y = -4

what is the equation of a line that is perpendicular to -x+7y=42 and goes through (-2,-1) in slope intercept form
Answer:
y = -7x - 15Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes
Given line
- x + 7y = 42In slope-intercept form it is
- x + 7y = 427y = x + 42y = 1/7x + 6Perpendicular line has slope - 1/(1/7) = - 7 and its equation is:
y = - 7x + bFinding b using the point (-2, -1)
-1 = -7(-2) + b-1 = 14 + bb = -1 - 14b = -15So the line is
y = -7x - 15add one line to each of the diagrams below so that the resulting figure has rotational symmetry but no line symmetry.

{6x + 4y = 18
{ 2x - 4y = -10
Answer: (1, 3)
Step-by-step explanation:
Answer:
6x+4y+2x-4y = 18+(-10)
8x = 8
x = 1
6x+4y = 18
6*1+4y = 18
4y = 18-6
4y = 12
4y/4=12/4
y= 3

Chiara had $5,700 in medical expenses last year. Her medical insurance covered 80% of these expenses. The IRS allows medical and dental expenses deductions for the amount that exceeds 7.5% of a taxpayer’s adjusted gross income. If Chiara’s adjusted gross income is $35,432, how much can she claim as a medical deduction? Explain
Using proportions, it is found that she can claim amounts greater than $2657.4 as a medical deduction.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, her adjusted gross income is $35,432, and she can claim deductions for amount's that exceed 7.5% of this, hence:
0.075 x 35,432 = $2657.4.

A medical delivery services charges $10 for a house call plus $0.50 per mile. The situation is represented by the equation c=0.5m+10 where m represents the number of miles the delivery is from the office and c represents the cost of the delivery. Calculate the total cost of a medical service delivery if the number of miles driven is 75.5 miles. Write your answer as an ordered pair (m,c).
Answer:
$47.75
Step-by-step explanation:
Where are given that the cost of medical service delivery is given by the expression
c=0.5m+10
m= the number of miles
when the number of miles is 75.5 mile we want to find the cost
put m=75.5 in the expression
c=0.5(75.5)+10
solving for c we have
c=37.75+10
c=47.75
Therefore the cost will be $47.75 for a distance of 75.5miles
