a quarter = 25 cents

so 4*25 = 100

a dime = 10 cents

so you would have 10x ( with x being the number of dimes

Write the slope-intercept form of the equation of the line described below.

prisoha [69]

The equation of the line is $y=-\frac{2}{5}x-5$

Explanation:

Given that the line passes through the points (-5,-3)

The slope of the line is $m=-\frac{2}{5}$

We need to determine the equation of the line.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Let us substitute the points (-5,-3) and the slope $m=-\frac{2}{5}$ in the above formula.

Thus, we have;

$y+3=-\frac{2}{5}(x+5)$

Simplifying, we get;

$y+3=-\frac{2}{5}x-2$

Subtracting 3 from both sides of the equation, we get;

$y=-\frac{2}{5}x-5$

Hence, the equation of the line in slope - intercept form is $y=-\frac{2}{5}x-5$

Frannie is two years older than 3 times her daughter's age. If Frannie is 47, how old ids her daughter?

SVEN [57.7K]

The answer is 15. Her daughter is 15 years old.

In order to find this we need to work backwards. First let’s subtract 2 from Frannie’s current age.
That gives us 45. We know that her daughter is 3 times younger so now all we need to do is divide by 3.
That gives us fifteen.

Hope this helped !!
