Hello,
answer A
4x+2y=11
x-2=-2y==>2y=-x+2
4x-x+2=11==>3x=9==>x=3
2y=-3+2==>y=-1/2
Yes, it’s a function because there is no repeating x-values,
Answer:
Step-by-step explanation:
Is these type of questions the decimal, (the little dot between the numbers) is really important.
2.094<=>2.702 In both of the equations there is a 2, and then the decimal, what numbers are next? 7, and 0. Which one of those it bigger? 7!!!!
so 2.094<2.702
9514 1404 393
Answer:
z = 14.4
Step-by-step explanation:
The angle bisector divides the sides proportionally.
z/12 = 6/5 . . . . . . . . . write a proportion*
z = 12(6/5) = 72/5 . . . . . multiply by 12
z = 14.4
_____
* We consider the proportion easier to solve if the unknown is in the numerator. Then the solution is found by multiplying the equation by that denominator.
The distance between Mary and Rogers houses is 2.47 miles.
<u>Step-by-step explanation:</u>
From the given information we can form a right angle triangle.
Refer to the image given below.
N mentions the north and W mentions the south.
S denoted the School.
M denotes Mary's home - 2.1 miles away from School and forms one side of the triangle.
R denotes Roger's home - 1.3 miles away from School and forms another side of the triangle.
The distance between their houses will be the hypotenuse side of the triangle.
Hypotenuse side = .
= .
= .
=.
= 2.47.
Distance between their houses =2.47 miles.
