Answer:
See explaination
Step-by-step explanation:
While graphing inequalities, think of the inequality sign as an equal sign.
So, y=mx+b.
Say the inequality was y>3x+7, I would think fo the > as an equal sign.
So, in your head, "write" it like this: y=3x+7. Hope this helps.

15 are boys and 23 are girls. If three members are selected to lead the parade, find the
probability that all three are girls.
Answer:
60.5% chance
Step-by-step explanation:
it is 23/38, since there are 23 girls and 38 ppl in total
If three members are selected to lead the parade, 23/38 is the probability that all three are girls.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given,
The number of students involved in planning the homecoming parade are thirty eight 38.
Among these thirty eight students, there are fifteen number of boys 15 and Twenty three number of girls (23).
Given a condition that If three members are selected to lead the parade,
We need to find the probability of all three girls.
The number of students =P(B)=38
The number of girls=P(A)=23
The probability of all three girls is P(A)/P(B)
23/38
Hence 23/38 is the probability that all three are girls.

Find the slope of a line that is perpendicular to the line
y = -1/8x +3
Answer:
The slope of a line that is perpendicular to the line
y = -1/8x +3 will be: 8
Step-by-step explanation:
Given the equation
y = -1/8x +3
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is -1/8.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be:
[tex]\frac{-1}{\frac{-1}{8}}=8[/tex] ∵ [tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}[/tex]

x+2
Divide the following using synthetic division
Answer:
x-5+ [tex]\frac{3}{x+2}[/tex]
Step-by-step explanation:
If x+2 is a factor, -2 is a zero. So we can put -2 in the left-hand corner of your synthetic division, bring the coefficients down so you'll have a set up like this:
-2 | 1 -3 -7
____________
1. bring down the 1:
-2 | 1 -3 -7
____________
1
2. multiply that by -2 and enter the result underneath 3:
-2 | 1 -3 -7
-2
___________
1
a. then, add through:
-2 | 1 -3 -7
-2
___________
1 -5
3. Do the same for -5 (multiply by the zero -2), enter that underneath -7 and add through:
-2 | 1 -3 -7
-2 10
___________
1 -5 3
Now, reassign the coefficients to their x. Because we already factored out an x with the zero, the 1 is assigned to 'x' rather than back to '[tex]x^{2}[/tex]'. The '-5' will not have an x attached. '3' is your remainder and cannot be divided out any further, so it will be written as [tex]\frac{3}{x+2}[/tex]. Finally, just put them back together to get x-5+[tex]\frac{3}{x+2}[/tex].

An airplane travels 780 miles in 4 hours. Make a table and graph to show the mileage for 2,8, and 12 hours. Is there a direct variation? Explain.
PLS HELP ME ON THIS QUESTION!!
Answer:
Please check the explanation.
Step-by-step explanation:
As an airplane travels 780 miles in 4 hours.
We need to determine the table and graph to show the mileage for 2,8 and 12 hours.
as
The airplane covers the distance in 4 hours: 780 miles
so
The airplane covers miles in 1 hour will be: 780/4 = 195 miles
Hence, the table can be calculated as:
Hours Distance Mileage in Miles
[tex]2[/tex] [tex]2\times195\:=\:390[/tex] miles
[tex]8[/tex] [tex]8\times195 = 1560[/tex] miles
[tex]12[/tex] [tex]12\times195 = 2340[/tex] miles
It is clear from the table that it is a direct variation as the constant is 195 miles per hour.
Please check the attached graph. The graph clearly indicates a direct variation.

Answer:
43°
Step-by-step explanation:
1. You need to create an equation: 3c+64+5c+82=90°
(Why 90°?)- this is a right triangle as you can see the little square
2. Then combine like terms
8c+146=90°
3. Subtract 146 from both sides
4. 8c=-56
5. Then divide 8 from both sides
C= -7
6. Then plug in -7 in 3c+64 and solve!
7. The final answer is 43

*x=4,y=0
*x=3,y=1
*x=3,y=0
*x=4,y=1
please answer step by step
Step-by-step explanation:
2x+4y=8
3x-4y=12
2x+4y+3x-4y=8+12
cancel +4y and -4y
therefore 2x+3x=20
5x=20
x=20/5
x=4
Sibstituting x=4 in 2x+4y=8
2x+4y=8
2*4+4y=8
8+4y=8
4y=8-8
y=0/4
y=0
x=4
