Answer:
-12 3/5
Step-by-step explanation:
-4 3/10 - 8 3/10
The signs are the same so we add and then take the sign
4 3/10 + 8 3/10
Add the whole numbers
4+8 = 12
Add the fractions
3/10 + 3/10 = 6/10
Simplify the fraction
6/10 = 3/5
Put them together
12 3/5
Add the sign
-12 3/5
F(x)=2x+1
you can use a table of values for a diagram and graph the line
Rx - sx + y = b
WHEN SOLVING FOR X :
rx - sx + y = b
We must get x onto it's own side, so subtract y from both side.s
rx - sx = b - y
Then, factor out x.
x(r - s) = b - y
Then, divide both sides by (r - s).
x(r - s) ÷ (r - s) = b - y ÷ (r - s)
Simplify.
x = b - y / r - s →

WHEN SOLVING FOR Y :
rx - sx + y = b
We need to isolate y, so get rid of everything BUT y on the left side.
Subtract rx from both sides.
-sx + y = b - rx
Then, add sx to both sides.
y = b - rx + sx

The LCM of 10 and 14 is 2.
Answer:
D one real solution
Step-by-step explanation:
x^2 - 8x + 16 = 0
This is in the form
ax^2 +bx + c = 0
so we can use the discriminant to determine the number of solutions
b^2 -4ac
(-8)^2 -4(1)(16)
64 - 64
0
Since the discriminant is zero, there is one real solution.
