Answer: The interest is $453.60.

What is the equation of the line whose y-intercept is 3 and slope is 1? y = x - 3 y = x 3 y = 3x 1 user: what is the slope of a

Lesechka [4]

A)

y = mx + c

<span>y = 1x + 3
</span>
<span>y = x + 3
</span>
b)
y = 2x ? 5 comparing to y = mx + c, slope = m

slope = 2.

But for a perpendicular line, we take the negative reciprocal,

Answer:

m=-29/3 and n=65/3

Step-by-step explanation:

The given system has equations:

3m+3n=36

8m+5n=31

Multiply the top equation by 5 and bottom equation by 3 to get:

15m+15n=180

24m+15n=93

Subtract the top equation from the bottom equation to get:

9m=-87

Divide both sides by 9

$m = - \frac{29}{3}$

We substitute this value into the first equation to get:

$3( - \frac{29}{3} ) + 3n = 36$

$3n = 36 + 29$

$3n = 65$

$n = \frac{65}{3}$
