For which valies of A, B, and C will Ax + By = C be a horozontal line through the point (-4, 2)?
Answer: B=1, C=2 and A =0.
Step-by-step explanation:
On a coordinate plane , a horizontal line is parallel to x-axis with 0 slope(m) .
Every horizontal line is written as y=c [∵ y= mx+c , here m=0 ]
Here value for x changes but values for y is fixed as c.
If the horizontal line passes through (-4,2), so for some point x= -4 and y=2.
So, Equation of line must be y=2, which can be written as (0)x+(1)y =2
By comparing this to Ax + By = C, we get B=1, C=2 and A =0
Use the equation y=-3x if the x-value is 2 1/3

Three students have started a fence-painting business. Working together, Pragnesh and Qazi can paint the fence in 2 hours. Similarly, Pragnesh and Ronghui can paint the fence in 3 hours when they work together. Finally, when Qazi and Ronghui work together, they can paint the fence in 4 hours. How long would it take if all three students worked together to paint the fence
Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi = [tex]\frac{1}{2}[/tex] half of the fence
pragnesh and roghui = [tex]\frac{1}{3}[/tex]
qazi and roghui = [tex]\frac{1}{4}[/tex] quarter of the fence
time taken when they all work together
= [tex]\frac{1}{2}[/tex] + [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{4}[/tex]
= [tex]\frac{13}{12}[/tex]
= [tex]\frac{12}{13}[/tex]
= 0.9231 × 60(mins)
= 55.4 mins

Consider the equation 2x +2y =8
Answer:
in slope intercept form it would be y = -x + 4
Step-by-step explanation:
your equation: 2x +2y =8
subtract 2x from both sides: 2y = -2x + 8
divide both sides by 2: y = -x + 4

Answer:
G (-2, -3) is in the solution set
Step-by-step explanation:
Finding the solution set
You are given the boundary lines for the inequalities, but the graph does not show the solution set.
The line for inequality y < -2x -4 is the one with negative slope that extends from upper left to lower right. The relation of y to the comparison symbol is ...
y <
indicating that y-values in the solution set will be less than those on the line. The line itself is NOT included in the solution set. That is, "shading" will be below and left of the line.
__
The line for inequality 2x - 4y ≤ 8 is the one with positive slope. Considering the variable with the positive coefficient, its relation to the comparison symbol is ...
x ≤
indicating that x-values in the solution set will be less than (or equal to) those on the line. The line IS included in the solution set. Shading will be above and left of the line with positive slope.
Then the doubly-shaded area is the quadrant at the left side of the X where the lines cross. The lower boundary of that is included in the set, while the upper boundary is not.
__
Considering the points
Now that you know the location of the solution set, you can decide whether any given point is in it, or not.
Plotting the points, you find that F and G are on the boundary lines, and H and J are outside the solution set. Point F(-2, 0) is on the upper boundary line, so is not in the solution set, either.
The point listed in choice G, (-2, -3) is in the solution sets of both inequalities.

Convert 4 3/7 into an improper fraction
Answer: The improper fraction is 31/7.
Explanation: For calculating an improper fraction, you multiply the whole number with the denominator and then add that answer to the numerator. In this situation, it is 4x7, which equals 28. Add 3 to 28, which equals 31. The answer is 31/7.

Henry has 96 marbles. He is packing containers with 8 marbles in each container. How many containers, c, does Henry need to pack all the marbles?
96 − c = 8
96 = 8 x c
c = 96 + 8
8 ÷ c = 96
Answer:
96 = 8 times c
Step-by-step explanation:
96 divided by 8 = 12
12 times 8 = 96
BRAINLIEST PLEASE
The number of containers, c, that Henry needs to pack all the marbles will be B. 96 = 8 x c.
Since Henry has 96 marbles and is packing containers with 8 marbles in each container, the equation to solve the number of containers needed will be;
96 = 8 x c.
96 = 8c
c = 96/8
c = 12
Therefore, 12 containers will be needed.

Given:
A number line.
To find:
The correct values for points A, B, C and D.
Solution:
From the given number line is it clear that there are three marks between any two consecutive integers which divide the number line between those integers in 4 equal parts.
It means, one mark = [tex]\dfrac{1}{4}[/tex].
In the number line, point A is at -2. So,
[tex]A=-2[/tex]
D is 1 mark below 0.
[tex]D=-\dfrac{1}{4}[/tex]
C is mark below -1.
[tex]C=-1-\dfrac{1}{4}[/tex]
[tex]C=-(1+\dfrac{1}{4})[/tex]
[tex]C=-1\dfrac{1}{4}[/tex]
B is 3 units below -1.
[tex]B=-1-3(\dfrac{1}{4})[/tex]
[tex]C=-1-\dfrac{3}{4}[/tex]
[tex]B=-(1+\dfrac{3}{4})[/tex]
[tex]B=-1\dfrac{3}{4}[/tex]
So, [tex]A=-2,B=-1\dfrac{3}{4},C=-1\dfrac{1}{4},D=-\dfrac{1}{4}[/tex]
Therefore, the correct option is A.
A micro-photograph of a human hair shows the hair magnified 150 times. If the hair is
2 cm wide in the photograph, what is the actual width of the hair? Express your
answer in mm, rounded to 2 decimal places
Answer:
The actual width of the hair is 20 / 150 = 0.13 mm
Step-by-step explanation:
Scaling
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling in several applications of real-life.
The human hair is magnified 150 times by a micro-phtograph. This is the scale factor.
The hair can be seen 2 cm wide in the photograph.
Converting to millimeters, 2 cm = 2*10 = 20 millimeters.
The actual width of the hair is 20 / 150 = 0.13 mm

given cot A= 40/9 and that angle A is in quadrant 1 find the exact value of sec A in the simplest radical form using a rational denominator
Answer:
41/40Step-by-step explanation:
Given cotA = 40/9
1/tanA = 40/9
tanA = 9/40
According to SOH, CAH, TOA
tan A = 9/40 = opposite/adjacent
Get the hypotenuse
hyp² = opp²+adj²
hyp² = 9²+40²
hyp² = 81+1600
hyp² = 1681
hyp = √1681
hyp = 41
Het sec A
sec A = 1/cosA
Since cos A = adjacent/hypotenuse
cos A = 40/41
secA = 1/(40/41)
SecA = 41/40
Hence the exact value of secA is 41/40
