Write the equation in standard form using integers: y = -2/5x - 3

1 answer:

7 0

Let's assume you meant y = (-2/5)x - 3.

-2/5x could be misinterpreted.

First, clear out the fraction(s). To do this, mult. both sides of the above eq'n by 5.

Result: 5y= -2x - 15. Add 2x to both sides. The resulting equation is what you wanted: an equation in the form Ax + By = C (standard form).

Please help! 15 points! <br><br> Btw, you cannot answer in the file.....that's just a pic.....

You can find the value of x using the trigonometric function of cosine.

cos x = adj/hyp
cos 49 = x/55
55(cos 49) = x
36.083 = x

Hope I am right :)

Amayo943,

Remember that with exponents you have to multiply the number of exponets by the same number it's in for example: $1^2 = 1 \times 1$ In this case you need to know that:

$15^2 = 15 \times 15$
$15 \times 15 = 225$
$=225$

Therefore your answer is "225."

Hope this helps!
