Answer: a) y=0.50x+15  

b) The graph of this equation form on a coordinate plane is a line.

c) Slope  =0.50 and y-intercept = 15

Step-by-step explanation:

Let x = Number of miles driven by car

Given: The cost of renting a car for a day is $0.50 per mile plus a $15 flat fee.

a) Total cost = 0.50x+15

If y =total cost of renting the car, then y=0.50x+15   (i)

b) Above equation is similar to y= mx+c  (ii) [m = slope , xc=y-intercept] which a linear equation .

So the graph of this equation form on a coordinate plane is a line.

c) Comparing (i) and (ii)

m=0.50 , c=15

Slope  =0.50 and y-intercept = 15

Step-by-step explanation:

I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

Answer:  C) 3pi

pi is irrational, and so is 3pi

The expression 3pi+0.4 is overall irrational as well.

If x is irrational and y is rational, then x+y is irrational

This is why choice C is the answer.

The other answer choices are rational values which would make the sum rational, so that's why we can rule them out.

Answer:

{1,1,2,2,4,4,8,8}

Step-by-step explanation:

In Finding The Factor Of A Number You Need To Find A multiplication of Two Numbers That Gives The Product 8.

•So keeping this in mind you can make multiples of numbers which has an outcome of 8. So;

1×8=8 {So 1 is a factor of 8 and note that any number multiplied by 1 is the number itself}

2×4=8{Two multiplied by four is going to give you 8 that's why it's a factor of 8}

3×?=8{There is no number which can be multiplied by 3 which has it's outcome as 8 so 3 isn't a factor}

4×2=8{4 multiplied by 2 is the same as 2 multiplied by 4 so you can see that when you multiply two numbers and it has it's product as 8 those two numbers that you multiplied to get the 8 is a factor of 8}

5×?=8{With the number 5 you can see that there is no number which can be multiplied by 5 which has its outcome as 8 so 5 is not a factor of 8}

6×?=8{With the number 6 you will not get any number which can be multiplied by 6 to give you 8 so 6 isn't a factor of 8}

7×?=8{With the number 7 too you won't get any number to be multiplied by 7 which is going to give you 8 that's why it isn't a factor of 8}

8×1=8{With the number 8 you can clearly see that when 8 is multiplied by 1 the product is 8 so that makes it its factor}

After finding the multiplication of Two Numbers that are going to give you 8, you can conclude that you have found the factors of 8 and note that any number above 8 can't be a factor of 8.

So we can conclude that the Factors of 8 are;

w=9

Answer:

Today: Friday, 06 November 2020

_______________________________

2 (w + 3) = -2(w - 21)

2w + 6 = -2w + 42

2w + 2w = -6 + 42

4w = 36

w = 9

Answer:

Answer: Around 1000 students would buy a school lunch.

Step-by-step explanation:

We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.

In total we have 20 + 14 = 34 students, this will be our 100%.

The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.

p1 = (14/34)*100% = 41.18%

And the percentage of students that buy lunch at school can be computed in the same way:

p2= (20/34)*100% = 58.82%

Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.

Then the exact number will be:

N = (58.82%/100%)*1700 = 1000

Around 1000 students would buy a school lunch.

Answer: 10

Step-by-step explanation:

The value of k is 10.5.

An angle is a shape created by two rays or lines that meet at the same terminal.

Here,

∠XZY = (4k + 5)°

∠YXZ = (6k + 10)°

The exterior angle M = 115°

Therefore,

∠XYZ = 180 - 115

∠XYZ = 60°

So, we can write that,

∠XZY + ∠YXZ + ∠XYZ = 180°

(4k + 5)° + (6k + 10)° + 60° = 180°

10k + 75° = 180°

Therefore,

k = 105/10

k = 10.5

Hence,

The value of k is 10.5.

Answer:

y = -x + 6

Step-by-step explanation:

Answer: [tex]y = 3x + 2[/tex]

Step-by-step explanation: [tex]2x + 3y = 6[/tex] in y-intercept form is [tex]y=\frac{-2}{3}x+2[/tex]. From this, we can make [tex]y=mx+2[/tex].

Answer:

-8

Step-by-step explanation:

Subtract 5 from both sides of the equation:

2+5=2−3

2+5−5=2−3−5

Simplify:

2=2−8

Subtract 2 from both sides of the equation:

2=2−8

2−2=2−8−2

Simplify:

0=−8

The solution to the algebraic expression has no solutions.

An algebraic expression comprises numbers, variables, and arithmetic operations with the aim of determining and finding a solution to the variables.

From the given expression, we have:

2x + 5 = 2x - 3

subtract 2x from both sides, we have:

2x -2x + 5 = 2x -2x - 3

5 = -3

Therefore, the solution algebraic equation has no solution since we don't have a variable to solve.

Answer:

70

Step-by-step explanation:

Everything needs to add up to 180. So you have 90 and 20 you will add them and you’ll get 110. Since you want to find the missing measurement you will subtract 180-110 and you’ll get 70. The missing angle is 70. To check: 90+20+70=180
