It is A how is this hard.
A. 2y6 + 4x2y2 + 10x + 12
B. 2y3 – 4xy2 – 3x + 12
C. 2y3 + 4xy2 + 10x + 9
D. 2y3 + 4xy2 + x + 12
a) only (1,2)
b) only (2,4)
c) both (1,2) and (2,4)
d) neither
First simplify the equation.
3x+3y= -x+5y
4x=2y
2x=y
y=2x
Means that the y value is 2 times the x value.
answer: C but there are more solutions than just (1,2) and (2,4)
B)75degrees
C)105degrees
because all triangles angles add up to equal 180, and a right triangle has a 90 degree angle. you subtract 90 and 15 from 180 and that number will be the size of the remaining angle
180-90=90
90-15= 75
the answer is B) 75degrees
The inequality that represents the number of toll passes without having to add any value to the toll pass is 18.
It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Toll pass accountvalue = $32
Amount deducted with each toll pass = $1.25
The amount in the account after which value is added to the account.
= below $10
The inequality that represents the number of toll passes.
32 - 1.25x < 10
Solve for x.
32 - 1.25x < 10
32 - 10 < 1.25x
22 < 1.25x
1.25x > 22
x > 22/1.25
x > 17.6
Thus,
The number of tollpasses is 18.
