Answer:
-3x + 4y = 40.
Step-by-step explanation:
Let's convert the equation to standard form:
y - 4 = 3/4(x + 8)
y - 4 = 3/4 x + 6
y = 3/4x + 10
Multiply through be 4:
4y = 3x + 40
-3x + 4y = 40 (answer).
Answer:
7-x
Step-by-step explanation:
49 - x^2 is a perfect square so
it factors to :(7+x)(7-x)
since there is a negative in 49 - x^2, it would make sense that the answer would be a negative to get that negative answer in the first place (negative times a positive equals a negative)
Forgive me for my lame explanation :')
Answer:
Step-by-step explanation:
Split the triangle into a 30-60-90 triangle. Since you have LM from that triangle, you can figure out the other sides. Then, using the leg from that triangle, the one next to it is a 45-45-90 triangle, meaning it's isosceles.
KM = 30 + 10√3
KL = 10√6
A rational number can be written as "a ratio of integers".
(That's a fancy name for "a fraction".)
If you make 8 times 0.8 (because there is 8y so that means is there is eight 0.8), 8 times 0.8 is 6.4. so 40 minus 6.4 equals to 33.6. so there is 4x. 33.6 divide 4 is 8.4.
x = 8.4
