Answer:
a) Graph are attached ,Red line shows the function y=3x-2 while blue line represents the function y=-5
b)(x,y)=(-1,-5)
Step-by-step explanation:
b)To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
c)Given that
y=-5
and y=3x-2
compare the right hand side of the above two equation and solve for x
3x-2=-5
or 3x=-3
or x=-1
so the solution to the given system of linear equations is =(-1,-5)
Step-by-step explanation:
Since 88 is for one night and 20 per night in fees and taxes.
Step 1 : Calculate for $88
make N the subject of formula
N= 1
Step 2: Calculate for $20
make N the subject of formula
N = 1
Answer:
d- all students from each grade
Step-by-step explanation:
Lets use elimination to solve the system of equations. We do this by adding the two equations terms together.
a + b = 5
a - b = 3
(a + a) + (b + (- b)) = (3 + 5)
2a + 0 = 8
We can then solve this new equation for a.
2a = 8
a = 4
After this, we can plug in the value of a into one of the equations and solve for b.
a + b = 5
4 + b = 5
b = 1
You're correct, the answer is 1.
47, you would add the seventeen to the opposite side.
