Answer:

(f-g)(2)=14

Step-by-step explanation:

We are given the two functions:

f(x)=3x^2+1\text{ and } g(x)=1-x

And we want to find the value of:

(f-g)(2)

This is equivalent to:

(f-g)(2)=f(2)-g(2)

Substitute:

=(3(2)^2+1)-(1-(2))

Evaluate:

=(3(4)+1)-(1-2)=(12+1)-(-1)=13+1=14

Therefore:

(f-g)(2)=14

Help me please. I dont understand this question.
ziro4ka [17]

Answer:

y = 100°

Step-by-step explanation:

I can't see the full question, but I'm guessing you need to find the measure of angle y.

The total angle sum of a polygon can be calculated with the formula

T = 180°(n - 2)   where T is the total angle measure, and n i the number of sides.

For our shape, there are 4 sides, so n = 4.  Plug that in and simplify...

T = 180°(4 - 2)

  T = 180°(2)

      T = 360°

We are given 3 of the angles, so angle y is

y = 360 - 107 - 104 - 49

    y = 100°

To solve the inequality m/-7<(or equal to) 14 , what should be done to both sides?
Marizza181 [45]

Answer:

\large\boxed{m\geq-98}

Step-by-step explanation:

\dfrac{m}{-7}\leq14\\\\-\dfrac{m}{7}\leq14\qquad\text{change the signs}\\\\\dfrac{m}{7}\geq-14\qquad\text{multiply both sides by 7}\\\\7\!\!\!\!\diagup^1\cdot\dfrac{m}{7\!\!\!\!\diagup_1}\geq(7)(-14)\\\\m\geq-98

Jim is saving nickels, dimes and quarters to buy a baseball mitt. He has 12 more
Harrizon [31]

Answer:

36 quarters   48 dimes  64 nickels

Step-by-step explanation:

quarter = q

dime = q+12

nickel = 2q-8

$17 = 1,700 cents

(q)25 + (q+12)10 + (2q-8)5 = 1,700

25q +10q+120  +10q-40 =1,700

45q+80 = 1,700

45q = 1620

q= 36      

 36     QUARTERS x25 =  900cents

 48 DIMES    x10      =         480 cents

  64 NICKELS x 5 =             320 cents

  TOTAL                              1,700 cents ($17)
