The answer is b and i know that cause just david’s
Given that in triangle XYZ and MPN XY=MP, YZ=PN and the ratio of XZ to MN is 23/19.
Thus the possible size of angle Y given that mP=85 will be:
mY/P=23/19
mY/85=23/19
mY=23/19*85
mY=102.9
The approximate value is therefore mY=100

Answer:
3(4x + 1)(x - 4) Answer choice B
Step-by-step explanation:
-12x^2 + 45 + 12
You would take out the -3 in the equation.
-3(4x^2 -15x - 4)
You can then multiply the first 4 and the last -4 and get a -16. You can then find two numbers that would multiply to -16 and add to -15.
You would do this by listing the factors of -16, which the numbers 1 and -16 would work.
You would then substitute each value in for the 17x and add them together, which this is just separating the value 17x.
3(4x^2 - 16x + x - 4)
3(4x^2 - 16x)(x - 4)
You can then take ou ta four for the first function in the parentheses.
3(4x(x - 4) 1(x - 4))
Then you take the function from the outside and the inside.
3(4x + 1)(x - 4)
The answer to the question would be B.
Answer:
Step-by-step explanation:
y = total number charged.
x = number of animals vaccinated.
If she charges $20 as a base, this means it is a constant value.
She also charges $10 for each animal vaccinated, this can be written as 10x.
Therefore the equation for the total number charged (y) can be written as:
Total amount charged = $20 + $10 for every animal vaccinated.
y = 20 + 10x
Answer:
3800
Step-by-step explanation:
Variables:
O - Original cost
N - New cost
c - change factor
Step 1:
Recognize that if something decreases by 19%, it is worth 19% <em>less</em>
This means that the new price, fractionally, is 100% - 19% = 81%
So we can use c as 0.81 (81/100)
Step 2:
Write an equation to represent what is happening
N = O * c
Step 3:
Sub in what we know
3078 = O * 0.81
Step 4:
Rearange and solve
O = 3078 / 0.81 = 3800
