Answer:
y = x + 6
Step-by-step explanation:
A line that is perpindicular to y = -x + 20 would be y = x. Now, we have to solve for the y-intercept. Knowing the line must cross through (-4,2) we can solve for the y-intercept using the equation y = x which is just up one over one. Going over 4 units to get to x = 0 means going up 4 units to get to y = 6. Now we know the y-intercept is 6. This means the final equation is y = x +6.

Write the equation of the line that is perpendicular to the line y=(-1/5)x+9 and passes through the point (-2,-2)
Answer:
y = 5x + 8
Step-by-step explanation:
Recall that if two lines are perpendicular, their slopes are negative reciprocals of one another. Thus, given y = (-1/5)x + 9, the slope of any perpendicular is
-1
m = --------- = 5
(-1/5)
Starting out with the slope-intercept equation y = mx + b, we get:
-2 = 5(-2) + C, or C = 8
Thus, the desired equation is
y = 5x + 8
The equation of the line that is perpendicular to the given line is y=5x+8.
Given that, the equation of line y=(-1/5)x+9 and passes through the point (-2,-2).
What is slope of an equation?The slope formula is used to calculate the inclination or steepness of a line. It finds application in determining the slope of any line by finding the ratio of the change in the y-axis to the change in the x-axis.
If m is the slope of a line, then the slope of a line perpendicular to it is -1/m.
Now, slope =-1/5
-1/m = 5
Put m=5 and the point (-2, -2) in y=mx+c and simplify
That is, -2=5(-2)+c
⇒c=8
Substitute m=5 and c=8 in y=mx+c, we get y=5x+8
Therefore, the equation of the line that is perpendicular to the given line is y=5x+8.

A scientist needs 10 liters of a 20% acid solution for an experiment, but she only has a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and 40% solutions should she mix to get the solution she needs?
9514 1404 393
Answer:
4.3 L of 40% solution5.7 L of 5% solutionStep-by-step explanation:
Let x represent the number of liters of 40% solution in the mix. Then the total amount of acid in the mix is ...
0.40x +0.05(10-x) = 0.20(10)
0.35x +0.5 = 2.0
0.35x = 1.5
x = 1.5/0.35 ≈ 4.3 . . . . liters of 40% solution

5x – 3y = -19
Answer:
y = 5/ 3 x + 19/ 3
Step-by-step explanation:
Slope-intercept form, y = m x + b .
Answer:
y=5/3x+6 1/3
Step-by-step explanation:
To get into y-intercept form you need to get y alone...
5x-3y=-19 subtract the 5x
-3y=-5x-19 divide by -3
y=5/3x+19/3 simplify
y=5/3x+6 1/3
Which equation represents a line which is parallel to the line 7x-5y=-30?
Answer:
Y=7/5x+8
Is the answer to question don't ask me how I know I cheated
The equation y = 7x/5 + b represents a line which is parallel to the line 7x-5y=-30.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
We have an equation,
7x-5y=-30
Simplifying,
y = 7x/5 + 30/5
y = 7x/5 + 6.
The general formula of line parallel to a given line is,
y = 7x/5 + b, where b is the y-intercept of the line.
Therefore, y = 7x/5 + b is the required line.

Ingrid's curtain company is making curtains for a local hotel. She wants each curtain to be 36 inches long. At the fabric store, fabric is sold by the foot. If Ingrid's curtain company wants to make 64 curtains, how many feet of fabric will she need? 1 inch = 1 12 foot I just don't get it
Answer:
192 ft
Step-by-step explanation:
Number of curtains = 64
Length of each curtains = 36 inches
Total length of curtains = Number of curtains × Length of each curtains
= 64 × 36 inches
= 2,304 inches
1 inch = 1/12 foot
2,304 inches = 2,304 / 12 ft
2,304 inches = 192 ft
She will need 192 ft of the fabric to make 64 curtains each of length 36 inches
