Find the x-intercept and y-intercept of the following
equation
2x + 5y = -6
Answer:
x = -3
y = -6/5
Step-by-step explanation:
To find the x-intercept(s), substitute in 0 for y and solve for x.
2x + 5(0) = -6
x = -3
Find the y-intercepts.
To find the y-intercept(s), substitute in 0 for x and solve for y.
2(0) + 5y = -6
y = -6/5

Factor this trinomial.
x2 - 9x+ 20
O A. (x – 4)(x - 5)
O B. (x-2)(x+10)
O C. (x - 2)(x - 10)
O D. (x – 4)(x + 5)
The factorization of the given trinomial [tex]x^2 - 9x+ 20[/tex] is (x – 4)(x - 5). The correct option is A.
What is trinomial?A trinomial is a polynomial that has three terms. To factor a trinomial of the form [tex]ax^2 + bx + c[/tex], you need to find two binomials that multiply together to produce the original trinomial.
To factor the trinomial [tex]x^2 - 9x + 20[/tex], we need to find two numbers that multiply to 20 and add up to -9. These two numbers are -4 and -5. Therefore, we can write:
[tex]x^2 - 9x + 20 = (x - 4)(x - 5)[/tex]
Or, To factor [tex]x^2 - 9x + 20[/tex], you need to find two numbers that multiply to 20 and add up to -9. These numbers are -4 and -5 because -4*(-5) = 20 and -4 + (-5) = -9.
You can factor the trinomial as (x - 4)(x - 5).
Thus, the correct option is A.

If I understand this right:
3/4=24
24/3=8
8*4=32
You divide the number by the numerator, and then multiply that number by the denominator.
If you mean you want 3/4 of 24 then you divide 24 by 4, which equals 6. And then multiply 6 and 3, which equals 18

ollie is making salad dressing.He mixes 1 part vinegar to 2 parts oil.Ollie makes 450mls of salad dressing.how much oul does he use
Answer:
let one part =x
part of vinegar= x
part of oil =2x
part of oil +part of vinegar = 450ml
2x+x=450
3x=450
x=450/3
x=150
part of vinegar=150ml
part of oil= 300ml
The amount of oil used by Ollie is 300ml.
What is linear equation in one variable?
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
Suppose the vinegar is x ml.
So, the oil is 2x ml.
Ollie makes 450mls of salad dressing.
⇒ 2x + x = 450
Solve the above linear equation for x.
⇒ 3x = 450
⇒ x = 150ml
Therefore, amount of oil she used = 2 × 150ml = 300ml.
Hence, the amount of oil used by Ollie is 300ml.

Step-by-step explanation:
Everyone thought that Martha Mathy was trying to start a new fashion trend when she started wearing socks that did not match. her "look" started to catch on, and pretty soon all the kids at her school were wearing mixed-up socks, too. Rita Writer, a reporter for the school paper, interviewed Martha about the new sock trend. " Wat gave you the idea to wear mismatched socks?" Rita Asked.
"Its simple mathematics," Martha replied. "you see, I have 18 socks at home but no two are the same. with just these 18 socks, I can create over 100 unique pairs of mismatched socks." Rita found this hard to believe, so she checked it out. Was Martha correct?
Answer:
There are 153 combinations
Combinations - any two from eighteen is given by the formula 18C2 or 18! / (2!*16!)
= 18 * 17 / 2 = 153
OK that is the maths - now the explanation
The first sock can be any of 18
The second sock can be any of 17 (one already been selected and they must be mismatched)
Therefore there are 18*17 = 306 permutations she could make
However the question asks for "combinations" not "permutations"
A green sock on the right foot and a yellow sock on the left foot is deemed to be a different "permutation" to a yellow sock on the right foot and a green sock on the left foot. HOWEVER, they are regarded as the same "combination" in both cases you have one green and one yellow sock.
Therefore for combinations we must divide the 306 permutations calculated above by 2 = 153
FYI Walton has incorrectly given you the value of 18!. That would only apply if Martha Mathy had 18 feet!
