Mathematics
1 answer:
Olin [163]2 years ago
3 0

Answer:

X<-3b+5/-a

Step-by-step explanation:

Isolate x, move 3b to the other side, switching its sign to negative.

S1: -ax>5-3b

Next, divide both sides by -a, fully isolating x.

S2: x> 5-3b/-a

Since we divided both sides by -a, we switch the inequality sign per rule.

S3: x<5-3b/-a

9. Carla has $200 in her bank account.
Firdavs [7]

(a) Linear Equation:   f(x) = 200 - 20x

(b) x-intercept : (10,0)

(c) y-intercept : (0,200)

(d) Domain : {0,1,2,3,4,5,6,7,8,9,10}

    Range : {0,1,2,...,200}

Step-by-step explanation:

Step 1: As we can see in graph, money in Carla is decreasing in multiples of 20 can be referred as 20x.

Every week $20 is getting deducted from the total amount of $200.

Step 2: (a) So we can quote it in equation as,

f(x) = 200 - 20x

where x represents number of weeks

Step 3: (b) x-intercept is where value of y becomes 0.

So, referring graph we can determine x intercept as x = 10. Point (10,0). which also means no money left in account.

Step 4: (c) y-intercept is where value of x becomes 0.

So, referring graph we can determine y intercept as y = 200. Point (0,200). which is starting value of money in account.

Step 5: (d) Domain : {0,1,2,3,4,5,6,7,8,9,10}

                  Range : {0,1,2,...,200}

Determine whether the equation has no solution, one solution, or infinitely many solutions. 7(12 – 2 x ) = 4(3 – 3 x )
Alex777 [14]

Answer: The equation has one solution

Step-by-step explanation: First , open the brackets

7( 12 - 2x ) = 4 (3 - 3x )

84 - 14x = 12 - 12x

collect the like terms

84 - 12 = - 12x + 14x

72 = 2x

Therefore divide through by 2

x = 72/2

x = 36

Therefore, the equation has only one solution

AlladinOne [14]

Answer:

The  money Raven has left after she buys the concert ticket is $8 .

Step-by-step explanation:

As given

Raven has been babysitting to earn enough money to buy a concert ticket that costs $24.

She already had $12 and she earned $20 babysitting.

Total money Raven have = $12 + $20

                                         = $ 32

Money Raven has left after she buys the concert ticket = Total money Raven have - Cost of the concert ticket .

Money Raven has left after she buys the concert ticket = 32 - 24

Money Raven has left after she buys the concert ticket = $8

Therefore the  money Raven has left after she buys the concert ticket is $8 .
