Answer:
o find total, we'll need to add all the costs! There's the cost for the phone which is paid once, monthly fee for all the months you use it.
total = 50 + (30 × months )
In this case, the question wants the equation in x and y, so we can plug those in:
y = 50 + 30x
Step-by-step explanation:
Answer:
22
Step-by-step explanation:
484 = 2^2 × 11^2
√484 = 2×11 = 22
Answer: -245
Step-by-step explanation: The reason is because if you add -245 to -130 you will get her present score which is -375.
-245 + (-130)
determinant: 
(a) 
D<0 means there are no real roots. there are two complex roots with imaginary components.
(b) D=16+20=36>0
D>0 means there are two real roots
(c) D = 20^2-4*4*25 = 0
D=0 means there is one real root with multiplicity 2
Answer:
y=3x+10
Step-by-step explanation:
First, put the equation into point-slope form.
y-y1=m(x-x1)
y-4=3(x+2)
Next, distribute 3 to (x+2) and simplify.
y-4=3x+6
y=3x+10
