Have to write a slope intercept form from this equation 2x + 1.50y = 15

1 answer:

3 0

The equation is in standard form. Standard form is in this formula:
Ax + By = C
To convert a standard form to slope intercept form you first move Ax to the other side of the equation by inverse operations.
2x + 1.50y = 15
-2x -2x
1.50y = -2x + 15

You then divide B (From By) across the whole equation. (If you can't evenly divide make it a fraction)
1.50y = -2x + 15
1.50 1.50
y = -2/1.50x + 10

Slope (12,-18),(11,12)

olga nikolaevna [1]

If you are trying to find the slope using only these two points then you should first take note of what your X and Y values are. For instance, 12 & 11 are your X values and -18 & 12 are your Y values. Knowing this you can now find your slope by doing y2-y1/
x2-x1. You will get the fraction -30/1 or -30 which is your slope. Hope that made sense!

Number sentence is simply a sentence, that uses numbers and arithmetic signs.

The context that can be created from the sentence is: How many bits are there, in $32\frac 14$ bytes
The verbal meaning of $32\frac 14 \div \frac 18 = 258$ is: When $32\frac 14$ is divided by $\frac 18$ , the result is $258$

Given

$32\frac 14 \div \frac 18 = 258$

(a) Context or story

A context is as follows:

There are 8 bits in a byte; How many bits are there, in $32\frac 14$ bytes

(b) As a multiplication

$32\frac 14 \div \frac 18 = 258$

Change the division to multiplication as follows:

$32\frac 14 \times \frac 81 = 258$

Need help with this question!

Katyanochek1 [597]

Answer:

A = 0.85(b +47)
$143.65

Step-by-step explanation:

Since the number of bagels sold already is 47, the total number of bagels sold will be b+47. The revenue from each sale is $0.85, so the total revenue will be ...

A = 0.85·(b +47)

This equation can be written in different forms, but this satisfies the requirement for "an equation."

Since b is the number of addition bagels, when 122 additional bagels are sold, the value of b is 122. Then the equation becomes ...

A = 0.85·(122 +47)

A = 0.85·169 = 143.65

Revenue will be $143.65 when 122 additional bagels are sold.
