State the x- and y-intercepts of the function. -10x - 10y = -20

x=−y+2

y=−x+2

Step-by-step explanation:

x-intercept = (2,0) or just 2

y-intercept = (0,2) or just 2

Step-by-step explanation:

For any linear equation in standard form:

Ax+By=C

The y-intercept is C/B and the x-intercept is C/A. This is possible because at the y-intercept x=0 and at the x-intercept y=0. If this is hard to understand, here's the actual work:

Y-intercept:

A(0)+By=C

By=C

y=C/B

X-intercept:

Ax+B(0)=C

Ax=C

x=C/A

With this in mind, we can just plug in the values into our equations:

Y-intercept:

y = -20/-10

y = 2

X-intercept:

x = -20/-10

x = 2

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
