can you please explain slope, the y-intercept, how to find the equation and how to graph it properly?
Answer:
Slope is a line on a graph, you find slope with the m=yx+b equation. Y intercept is the point that the line crosses the y axis at, it is represented by b. X and Y in the equation are your coordinates. You graph it by starting at your y-intercept and going up in a straight line following the slope calculated.

Willie left the mall and traveled toward the town hall at an average speed of 40 km/h. Gabriella left two hours later and traveled in the opposite direction with an average speed of 70 km/h. Find the number of hours Gabriella needs to travel before they are 410 km apart.
Answer:
Gabriella need to 2.45 hours of travelling to be 410km apart from Willie.
Step-by-step explanation:
In order to make them 410km apart and the time included in it is to be found
we proceed as
Willie left the mall earlier and Gabriella left two hours before
so willie has travelled for 2 hours while Gabriella was still at the initial point
with this logic we find the hours Gabriella needs as follows
Willie Gabriella
←←←←←←←← →→→→→→→→→→
40km/h 70km/h
X hours X+2 hours
40*x+70(x+2) = 410
40x+70x + 140=410
110x=270
x=270/110
x= 2.45hrs

Decide whether there is enough information to prove that r is parallel to s. If so, state the theorem you would use.
A. No, there is not enough information.
B. Yes. Alternate Interior Angles Converse
C. Yes. Alternate Exterior Angles Converse
D. Yes.Consecutive Interior Angles Converse
E. Yes. Corresponding Angles Converse
Answer:
B. Yes. Alternate Interior Angles Converse
Step-by-step explanation:
The two angles shown in the figure above are alternate interior angles. Each is located within the two parallel lines intersected by the transversal, and they also lie on opposite side of the transversal.
The marked alternate interior angles are congruent. Therefore, lines r and s are parallel. So, by the Alternate Interior Angles Converse, lines r and s are parallel.
Therefore, the right response to the question is:
"B. Yes. Alternate Interior Angles Converse".
If x^2+x =3^2/3+3^-2/3 then prove that 3x^3+9x-8=0
x^2 + 2 = 3^2/3 + 3^-2/3
x^2 = 3^2/3 + 3^-2/3 - 2
x = √(3^2/3 + 3^-2/3 - 2)
x = 0.748888296
Substitute for x in 3x^3 + 9x - 8:
3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.
So it is proved.

What is the solution to the equation 13.7y – 10.6 = 6.2y + 19.4
Answer: hope this helps :)))
y=4
Step-by-step explanation:
Step 1: Subtract 6.2y from both sides.
13.7y−10.6−6.2y=6.2y+19.4−6.2y
7.5y−10.6=19.4
Step 2: Add 10.6 to both sides.
7.5y−10.6+10.6=19.4+10.6
7.5y=30
Step 3: Divide both sides by 7.5.
7.5y/7.5 = 30/7.5
y=4

Mr. Mohr wants to build a rectangular patio using concrete tiles that are 12 square inches. The patio will measure 13.5 feet by 43 feet. What is the area of the patio? How many concrete tiles will he need to complete the patio?
Answer: He will need 49 tiles.
Step-by-step explanation:
Given: The patio will measure 13.5 feet by 43 feet.
Area of patio = 13.5 feet x 43 feet [Area = length x width]
= 580.5 sq. feet
Since area of each concrete tile = 12 sq. inch
Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)
= 580.5 ÷ 12
= 48.375 sq. inch ≈49
Hence, he will need 49 tiles.
Answer:
49 tiles
Step-by-step explanation:
Answer: He will need 49 tiles.
Step-by-step explanation:
Given: The patio will measure 13.5 feet by 43 feet.
Area of patio = 13.5 feet x 43 feet [Area = length x width]
= 580.5 sq. feet
Since area of each concrete tile = 12 sq. inch
Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)
= 580.5 ÷ 12
= 48.375 sq. inch ≈49
Hence, he will need 49 tiles.
For some reason, in our history class, there are 14 boys than there are girls. If a total of 32 students are in the class, how many boys and how many girls are there?
Answer:
There are 23 boys and 9 girls in the class
Step-by-step explanation:
The given information is that the number of boys = 14 + The number of girls
The total number of boys and girls = 32
Let the number of girls = x
Therefore, we have;
The number of boys = 14 + x
The total number of boys and girls = 32 = The number of boys + The number of boys
The number of boys + The number of boys = 14 + x + x = 14 + 2·x
∴ The number of boys + The number of boys = 32 = 14 + 2·x
14 + 2·x = 32
2·x = 32 - 14 = 18
2·x = 18
x = 18/2 = 9
x = 9
Therefore, the number of boys is 14 + x = 14 + 9 = 23 boys
The number of boys = 23 boys
The number of girls = x = 9 girls
the number of boys = 23 boys
The number of girls = x = 9 girls
The number of girls = 9 girls
Therefore, there are 23 boys and 9 girls in the class.

Which algebraic expression represents the phrase "seven more than half of a number”?
o 7 -1/2x
o -7+1/2x
o 1/2x+7
o -1/2x-7
PLEASE HELPPPP
Answer:
C
Step-by-step explanation:
Seven more is addition (+7)
Half a number would be represented by 1/2, and since the number is unknown, it would be represented by a variable (in this case, x)
C is the correct response

A. f(x) = 5x
B. f(x) = 5 + 5x
0 Ç. f(x) = 7 + 5x
O D. f(x) = 12 + 5x
Answer:C. f(x)=7+5x
Step-by-step explanation:
12=5(1)+n
12=5+b
-b+12=5
-b=5-12
5-12=7
-b=7
f(x)=7+5x
I know this because I just answered this question and got it right
The equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The table is given,
From the data given in the table:
12 = 5(1)+n
12 = 5+b
b = 7
The function would be:
f(x) = 7 + 5x
Thus, the equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.

Nick has $3.90 in quarters and dimes, and the total number of coins is 27. How many quarters and how many dimes? Can I have some help with formatting?
Answer:
There are 19 dimes and 8 quarters
Step-by-step explanation: Q= Quarter and D=dimes
q+d= 27; q=.25 and d=.10;
.25q+.10d= $3.90
q= 27-d
.25(27-d)+.10d=3.90 >Distribute .25 through the parenthesis
= 6.75-.25d+.10d=3.90 >Combine like terms
= -.15d=3.90-6.75 >Subtract 6.75 from both sides of the equation
= -.15d=-2.85 >Subtract
= d=19 >Divide both sides by -.15
q= 27-d>>>>> q= 27-19
q= 8
