(Slope-Intercept to Standard Form) y=6/5 x How would I work this out?

1 answer:

8 0

6x - 5y = 0.

Since 6 represents x and 5 represents y, you have to write it as 6x and 5y. And it’s going to equal zero since there is no y-intercept.

Answer: b:70

Step-by-step explanation:

x^2=100

100 - (2*10 + 2*5 )= 100 - (20 + 10)

100 - 30 = 70

Which function could represent the value of a rare coin that increases over time? y=−32x+1y is equal to negative 3 halves x plus

KATRIN_1 [288]

The function that could represent the value of a rare coin that increases over time is; y = ²/₃x + 2

<h3>How to create linear equations?</h3>

We want to find which of the equations below could represent the value of a rare coin that increases over time

y = -³/₂x + 1

y = -²/₃x - 7y

y = ²/₃x + 2

y = ³/₂x - 6

Now, the general form of a linear equation in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, for the equation to be increasing over time, it means the slope must be positive and the y-intercept must also be positive.

Looking at the given options, the only one where slope and y-intercept is positive is y = ²/₃x + 2

Question 1(Multiple Choice Worth 2 points)

dusya [7]

Answer:

6x +47

Step-by-step explanation:

f(x) = 6x + 11

g(x) = x + 6

now f[g(x)]=by substituting values of g (x)

to f (x)

f[g(x)]=6 (x+6)+11

=6x+36+11

=6x +47

A shop sells pairs of trainers for £52 each. They make a percentage profit of 30% on each pair. What was the cost of each pair o

Sphinxa [80]

Answer:

£15.6

Step-by-step explanation:

Method 1:

You are trying to find 30% of £52.

Therefore:

$\frac{30}{100} * 52 = \frac{30 * 52}{100}$

If you solve this you will find that 30 × 52 = 1560, and 1560 ÷ 100 = £15.6.

So, the answer is £15.6.

Method 2:

You can solve 30% of £52 by using an algebra equation.

By using the rule that to convert a percentage to a decimal you divide by 100, you can change 30% to be 0.3.

Now, in order to write the equation, you will have to include 0.3 and 52.

The equation is:

0.3 * 52 = x

Once you multiply, you will find that the answer is £15.6.

I hope I helped!
