Answer:
-9-(-3)/0-(-3) = -3/3 = -1
y+9= -1(x-0) <u><em>Point Slope form</em></u>
y+9<u>-9</u>= -1x<u>-9</u>
y= -x-9 <em><u>Slope Intercept form</u></em>
y<u>+x+9</u> = -x-9 <u>+x+9</u>
y+x+9= 0 <u><em>General form</em></u>
Answer:
x = -43
y = -4
Step-by-step explanation:
In this question, you will have to find the value of x in terms of y using one of the equations and substituting the value in the other equation or vice versa.
Let's assume the numbers x and y, now we write the expressions.
x + y = -47
x - y = -39
Take the second equation and find x.
<u>Calculations:</u>
x - y = -39 (Add y on both sides)
x = -39 + y
Now that you got the value of x in terms of y, we can substitute.
<u>Calculations:</u>
(-39 + y ) + y = -47
2y - 39 = -47
2y = -8
y = -8/2 = -4
y = -4
Now that we got y, we can substitute that value in any of the equations to find x.
x - 4 = -47 or x + 4 = -39
x = -43
Answer:
The answer is the third bullet. (number 3)
A because it can be rearranged to the y = mx + c format. y = -1/40 x + 4
Answer: √5
2.7 is a rational number because it's a terminating decimal which means that the decimal does end and all terminating decimals are rational numbers.
-3 is a rational number because it's an
integer and all integers are rational.
√4 is rational because it's a perfect square which means that a number can be multiplied by itself to get 4 and that number is 2.
√5 is no rational! It's impossible to find a whole number multiplied by itself to give us 5 which means that it's
non-terminating and non-repeating.
