Answer:
y= -6x+5
Step-by-step explanation:
Since the lines are parellel the lines don't intersect AT ALL so they have the same slope. Moreover, since the point given is (0,5), given so that the point is on the y-axis and the line intersects it, the y coordinate since x is zero will by the y-intercept.
Hope this Helps!!
Answer:
2x - 2y = 14
x - y = 2
1.) x = 2+ y
2.) 2(2+ y) - 2y = 14
3.) 4 + 4y - 2y = 14
4.) 4y - 2y = 14 - 4
5.) 2y = 10
6.) 2y/2 = 10/2
7.) y = 5
x - y = 2
8.) x - 5 = 2
9.) x = 2 + 5
10.) x = 7
Therefore, x = 7 and y = 5
Step-by-step explanation:
1. First make one of the variables in any equation the subject of the formula
2. Then substitute the variables equating to the subject of the formula
3. Group the like terms,then solve the equation.
4. Replace the value you will find in the first equation into the other equation.
5. Repeat with the same
The easiest way is to try the point (-4,1), that is, x=-4, y=1,
to see which equation works.
b works.
The usual way to do it is to find the equation of the circle
standard form of a circle is (x-h)²+(y-k)²=r², (h,k) are the coordinates of the center, r is the radius.
in this case, the center is (-2,1), so (x+2)²+(y-1)²=r²
the given point (-4,1) is for you to find r: (-4+2)²+(1-1)²=r², r=2
so the equation is (x+2)²+(y-1)²=2²
expand it: x²+4x+4+y²-2y+1=4
x²+y²+4x-2y+1=0, which is answer b.
Answer: 37 fruit pies+42 fruit juices=79 total items
(a) 37*1.65= $61.05
42*1.36= $57.12
(b) Mr Sanchez's class earned more money.
(c) Mr. Sanchez's class earned $3.93 more than Mr. Kelly's class
$61.05-$57.12= $3.93
