Find the slope and the y-intercept of the line y=4x+6
Answer:
Slope: 4
Y-intercept: 6
Step-by-step explanation:
The equation is given to you in slope intercept form which is y=mx+b.
In this form m is the slope and b is the Y-intercept. Therefore all you have to do is take the value for m from the equation and put that down for the slope and the value for b as the y-intercept.
Please help!! I'm super confused

What is the cost of paving the path with bricks at rate of Rs.100 per m². When area of land is 63 m s
Answer:
Rs. 6300
Step-by-step explanation:
Given that:
Land area = 63m²
Rate of paving brick = RS. 100 per m²
Hence, to pave bring on a 63m² land area ;
Total cost of paving brick will be :
Cost per m² * land area
Rs. 100 * 63
= Rs. 6300

Answer:
㏒(2x²) = ㏒(2) + 2㏒(x)
Step-by-step explanation:
As given, ㏒(2x²)
As we know that ㏒(MN) = ㏒(M) + ㏒(N)
⇒㏒(2x²) = ㏒(2) + ㏒(x²)
As we know that ㏒(xⁿ) = n㏒(x)
⇒㏒(2x²) = ㏒(2) + 2㏒(x)
∴ we get
㏒(2x²) = ㏒(2) + 2㏒(x)

Kyle found that
31/97 = 0.3196. Without doing any computation, explain how we know
that Kyle is wrong.
I need the answer really quickly!!!
Answer:
The answer actually rounds to 0.3196, but the computation is so long, we just count it as 0.3196. The real answer would be 0.31958762886.

HELP ASAP 3.) Andy's Karpet Kleaning charges a $23 consultation fee, plus $17 per hour to clean carpets. Stanley
Steemer charges a $37 consultation fee, plus $13 per hour. After how many hours will the total charge be the
same? What is the charge?
Answer:
After 3.5 hours and the charge is $82.50.
Step-by-step explanation:
Setting up the equations equal to each other will give a solution (x-value) that makes both sides equal (the same price) after the same amount of hours (x-value).
13x + 37 = 17x +23
x = 3.5
Then plug the hours into either side to get the equal price.
13(3.5) + 37 = $82.50
OR
17(3.5) + 23 = $82.50
find the perimeter and area:
1. square with a side 2.4 m in length find the perimeter and area
2. rectangle with length (x+3) and width 7
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle?
Answer:
1= Perimeter =9.6
Area = 5.76m^2
Answer:
find the perimeter and area:
1. square with a side 2.4 m in length find the perimeter and area
answer:
length [l]=2.4m
area of square=l²=2.4²=5.76m²
perimeter of square=4l=4×2.4=9.6m
2. rectangle with length (x+3) and width 7
answer:
length [l]=x+3
Breadth [b]=7
perimeter of rectangle =2{l+b}=2(x+3+7)=2x+20
area of rectangle=l×b=(x+3)×7=7x+21
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle.
answer:
the term for the perimeter of a circle=2πr (when radius is given ) and πd (when diameter Is given)

Answer:
1) [tex]\frac{1}{2^7}[/tex] ; 2) [tex]11^7[/tex]
Step-by-step explanation:
1) Using the Power of a Fraction Rule [tex](\frac{a}{b} )^x = (\frac{a^x}{b^x} )[/tex],
[tex](\frac{1}{2} )^7 = (\frac{1^7}{2^7} )[/tex], which can just be simplified to [tex]\frac{1}{2^7}[/tex].
2) Using the Negative Exponent Rule, [tex]a^{-x} = \frac{1}{a^{x}}[/tex],
[tex](\frac{1}{11} )^{-7} = \frac{1}{\frac{1}{11^7}}[/tex], which can be simplified to [tex]11^7[/tex].

Answer:
arc AB = 90 degrees
x = 9
arc AD = 108 degrees
arc DC = 139 degrees
arc BC = 13 degrees
arc ADC = 247 degrees
Step-by-step explanation:
12x+(17x-14)+(2x+5)+90 = 360
31x+81 = 360
31x = 279
x = 9
arc AD = 12(9) = 108 degrees
arc DC = 17(9)-14 = 139 degrees
arc BC = 2(9)+5 = 23 degrees
arc ADC = 108+139 = 247 degrees

#13 and 14
Answer:
For number 13 you should get 14 is the width just divide what you got from multiplying the length and the other side. 2 and 95 could be possible answers of number 14.
Answer:
13. Width is 14 inches.
14. 5 and 38
Step-by-step explanation:
Volume (rectangular prism) = length*width*height
1428=17*w*6
w=1428/102
w=14 inches
Base area=length*width
∴Volume (rectangular prism) = Base area*height
190=Base area*height
Pick two numbers that multiply to give 190: 5 and 38.
