Let's start with simplifying this equation. Typically we have y = something, so let's rewrite it in this form.
3xy = -3
y = -3/3x
y = -1/x
Alright! Now, let's go ahead and solve for the y-intercept. Those only occur when x=0, so let's plug in 0 for x.
y = -1/0
Slight problem. Dividing by a 0 results in an imaginary number, or "undefined". In this case, there is no y-intercept.
Now we can solve for an x-intercept. These only occur when y=0, so let's set y to 0!
0 = -1/x
Well shoot! We have another problem. No regular number of x will give us a y=0. However, this problem isn't the same as our undefined one from before. Here, as x value approach infinity, we get closer and closer to 0. We can never actually hit 0, but we do approach it. I'm not sure how your teacher wants it answered, but strictly, there is no x-intercept. However, we can actually attempt to explain what is going on, which is that as x go to infinity, we APPROACH y=0.
Hope that helps, and please let me know if you need clarification on anything!
1 inch =2.5cm
lenght =30.25×2.5=75.625cm
width = 21×2.5=52.5cm
area of painting = 75.625×52.5=3970.3125cm²
Equivalent fractions are different fractions that name the same number. The numerator and the denominator of a fraction must be multiplied by the same nonzero whole number in order to have equivalent fractions
Answer:
D'(-2, 5), E'(3, 5), F'(3, 3), G'(-2, 3)
Step-by-step explanation:
Adding (-1, 2) to each of the coordinates gives ...
D +(-1, 2) = (-1-1, 3+2) = D'(-2, 5)
E +(-1, 2) = (4-1, 3+2) = E'(3, 5)
F +(-1, 2) = (4-1, 1+2) = F'(3, 3)
G +(-1, 2) = (-1-1, 1+2) = G'(-2, 3)
Answer:
the answer is 9
Step-by-step explanation:
why it 9 Add '2.7' to each side of the equation.
-2.7 + 2.7 + 0.3x = 9 + 2.7
Combine like terms: -2.7 + 2.7 = 0.0
0.0 + 0.3x = 9 + 2.7
0.3x = 9 + 2.7
Combine like terms: 9 + 2.7 = 11.7
0.3x = 11.7
Divide each side by '0.3'.
x = 39
Simplifying
x = 39
