Mathematics
1 answer:
iVinArrow [24]2 years ago
7 0

Answer:

Step-by-step explanation:

5a. 7 < x

b. 2< 2x

c. 8 > x

d. 3 > x/29

joe = j

christina = c

Aaron = a

j = 3a , c = a-6 total ages is 149

149 = j + c+ a

149 =  3a + a-6 + a

149 = 5a-6

add 6 to both sides

149 + 6 = 5a-6+6

155 = 5a

a = 155/5

a = 31

c = a - 6

c = 31 - 6

c = 25

ryzh [129]

Answer:

The third option is correct.

The domain of the function is given by

Domain = 0 \leq t \leq 40

The range of the function is given by

Range = 0 \leq V(t) \leq 200

Step-by-step explanation:

Sara bought a cell phone for $200 and its value has decreased at rate of $5 per month.

V(t) is the value of the phone and t is the number of months.

The domain of the function is the possible values of the number of months t.

The domain of the function is given by

Domain = 0 \leq t \leq 40

The range of the function is the values of V(t) that we get after substituting the possible values of the number of months t.

The range of the function is given by

Range = 0 \leq V(t) \leq 200

When the number of months is t = 0 then the value of the function is maximum V(t) = 200

When the number of months is t = 40 then the value of the function is minimum V(t) = 0

Therefore, the third option is correct.

Given that v=√u*u- 2qs. Make q the subject of the equation. Find the value of q in the equation if v=8, u=12, and s=40​
kifflom [539]

Answer:

Step-by-step explanation:

v=√u*u- 2qs

  1. \sqrt{20} x 20 - 2q40 = 8
  2. 2\sqrt{5} x 20 - 2q40 = 8
  3. 40\sqrt{5} - 2q40 = 8
  4. - 2q40 = 8 - 40\sqrt{5}
  5. -80q = 8 - 40\sqrt{5}
  6. q = (8-40\sqrt{5} ) / -80 = \frac{-1 + 5\sqrt{5} }{10} = 1.018

Find the larger of two consecutive integers if the larger is 149 less than twice the smaller.
snow_tiger [21]

Answer:

151

Step-by-step explanation:

Let x = the smaller integer and y = the larger integer.

We have two conditions:

(1)   x + 1 = y

(2)       y =  2x - 149      Substitute (1) into (2)

    x + 1 = 2x - 149        Add 150 to each side

x + 150 = 2x                 Subtract x from each side

        x = 150                Substitute into (1)

150 +1 = y

       y = 151

The larger integer is 151.

<em>Check: </em>

(1) 150 + 1 = 151

          151 = 151

(2)       151 = 2×150 -149

          151 = 300 -149

          151 = 151
