The answers are:
(2, -1)
(0, 3)
(-1, 5)
You just plug in the x values into the equation, solve, and see if you end up with the corresponding y value.
Answer:
20n - 4
Step-by-step explanation:
the product of 20 and a number means multiplying 20 by n (the variable representing the number)
to get four less than this product, you subtract 4
Answer: B) (x - 5)(x + 4)
Step-by-step explanation:
we’re looking for x intercepts at x = 5 and x = -4
x - 5 = 0; x = 5
x + 4 = 0; x = -4
(x - 5)(x + 4) is your answer
Well first do 20 children minus 8 girls to find how many boys there are:
20-8=16
So there are 16 boys. Therefore we can write the ratio of girls to boys as:
8/16
Then we can simplify this ratio by dividing it by 8 to get:
1/2
So the answer is the ratio of girls to boys in the group in simplest form is 1/2.
