Find the equation of the line.
Use exact numbers.

y = ___x + ___

Answer:

error= 0.1/2, 0.05

4.8 + 0.05 = 4.85

6.3 + 0.05 = 6.35

4.85 x 6.35 = 30.7975 cm (when rounded, gives 30.80 cm).

Step-by-step explanation:

Answer:

1 cm: 12.5 km

Step-by-step explanation:

Okay just find what the length of one cm equates to so

4/4=1

50/4=12.5

it's like making a unit measurement but yknow its scaling

so one cm (one unit in a way) equals 12.5 km.

Answer:

so substitute x with 6

y = 4 + 36 + 1

so y or f(x) would = 41

==================

10x - 7 = 4x + 5

= 10x - 7 - 4x = 5

= 10x - 4x = 5 + 7

= 6x = 5 + 7

= 6x = 12

= x = 12 ÷ 6

= x = 2 ✔️

Answer:

[tex]a^{\frac{15}{2} }[/tex]

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex]

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

([tex]a^{\frac{1}{2} }[/tex] × a)^5

= [tex](a^{\frac{1}{2}+1) }[/tex]^5

= [tex](a^{\frac{3}{2}) } ^{5}[/tex]

a = -3.

Step-by-step explanation:

5^a = 1/125

5^3 = 125

so 5^-3 = 1/125

Answer:

a = -3

Step-by-step explanation:

5^a = 1/125

Rewriting 1/125 as 1/5^3 = 5^-3

5^a = 5^-3

a = -3

Answer:

22w - 18  

Step-by-step explanation:

To find the perimeter we have to add up all the sides

10w-10+w+1+10w-10+w+1

combine light terms

22w - 18 would be our answer

Answer:

What? I don't understand your question.

Step-by-step explanation:

just no just n oh yeah btw shoot some

The y intercept means that $8 must be paid to step into the cab.

A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the total pay for x miles

Since $8 per ride and $0.35 per mile, hence the equation is:

y = 0.35x + 8

The y intercept means that $8 must be paid to step into the cab.

Answer:

  a) £210

  b) £1651.38

Step-by-step explanation:

After the reduction, the price is 1 -30% = 0.70 of what it was.

  0.7p = £147

  p = £147/0.7 = £2.10 . . . price before decrease

Answer:

The answer is D

Step-by-step explanation:

A cant be right because the graph isn't a straight line.

B cant be right because from 0 to 60 the graph the line goes at a(n) upward slope not a straight line.

Although the first part of question c is right, the second part is wrong. From 50-90 the ling goes at a downward slope via decreasing, which isn't equal like it said so question C is wrong.

So the correct answer is D

Answer:

B) y = 5x + 29

Step-by-step explanation:

A parallel line means it will have the same slope.

    So far our equation looks like this: y = 5x + b

We will now plug in (-6, -1) to solve for b.

    y = 5x + b

    (-1) = 5(-6) + b

    -1 = -30 + b

    29 = b

So our answer is y = 5x + 29

    This is option B

Answer:

One solution

Step-by-step explanation:

Well, let's find out by solving the equation for x and seeing how many possible values there are. Our answer could be no solution, one solution, or infinite solutions. So, let's get started by writing out our equation:

3(7x + 4 ) - 2x + 8 = 5x + 12

First, we'll distribute the 3 onto the values on the left:

3(7x) + 3(4) - 2x + 8 = 5x + 12

21x + 12 - 2x + 8 = 5x + 12

Now, we can combine like terms. They are underlined and boldfaced below:

21x + 12 - 2x + 8 = 5x + 12

21x - 2x + 12 + 8 = 5x + 12

19x + 20 = 5x + 12

Next, let's take away 5x from both sides:

19x - 5x + 20 = 5x - 5x + 12

14x + 20 = 12

Finally, we'll subtract 20 from both sides:

14x + 20 - 20 = 12 - 20

14x = -8

Now, all we have to do is divide both sides by 14.

14x/4 = -8/14

x = -4/7

It looks like there is only one solution for x: -4/7. Hopefully that's helpful!

Your answer is A = 12.375 and B = 5.625.

Hello!

Remember y=mx+b.

m is the slope and b is the y intercept.

So
