Answer: there are 2 terms
Step-by-step explanation: A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. ... Examples of single terms: 3x is a single term.
Answer:
x = -2
Step-by-step explanation:
3x+2=−4
3x+2−2=−4−2(Subtract 2 from both sides)
3x=−6
3x
/3
=
−6
/3
(Divide both sides by 3)
x=−2
2.)
average velocity=(change in distance)/(change in time), in this case:
v=(549 9/10)/(7 50/60)
v=(5499/10)/(470/60)
v=(5499/10)(60/470)
v=32994/470
v=70.2 km/hr

Make two position functions...
c=15t, and r=120-20(t-1)
c=15t, r=140-20t
They meet when c=r so:
15t=140-20t add 20t to both sides
35t=140 divide both sides by 35
t=4
So they will meet 4 hours after Cindy leaves at 1 pm, thus they meet each other at 5 pm.
check...
c=15(4)=60
r=120-20(4-1)
r=120-20(3)
r=60
S(x) = 2 - x²
t(x) = 3x
s(t(x)) = st(x)
s(t(x)) :
s(3x)
So in s(x) = 2 - x², to solve for s(3x) we replace x with 3x
s(x) = 2 - x²
s(3x) = 2 - (3x)²
= 2 - 9x²
st(x) = 2 - 9x²
st(-7) = 2 - 9*(-7)(-7)
= 2 - 9*49 = 2 - 441 = -439
st(-7) = -439
