Answer:

It will take her 14 months

Step-by-step explanation:

In this question, we are asked to calculate the number of months it will take kiera to increase her savings from 174 to 1350 if she adds a token of $84 to her savings each months.

Since we do not know the number of months, let’s represent this by m.

We model a linear equation to get m as follows;

Mathematically;

174 + 84(m) = 1350

Now we proceed to get m;

84m = 1350 - 174

84m = 1176

Thus, m = 1176/84 = 14 months

Answer: 14 months

Step-by-step explanation:

Current balance = $174

Amount added every month= $84

Proposed final balance= $1350

From the equation, the first term is 174 and common difference is 84.

The equation we will use is:

174 + 84x = 1350.

Collect like terms

84x = 1350 - 174

84x = 1176

Divide both side by the coefficient of which is 84

84x/84= 1176/84

X= 14

It will take 14 months for the money saved by Kiera to reach $1350.

Intercepts:
Tema [17]
An x-intercept is the point where the function passes the x axis at y=0.
The y-intercept is the point where the function crosses the y axis at x=0

1. It is an x-intercept, so y = 0. The ordered pair would be (-6, 0)
2. It is a y-intercept, so x = 0. The ordered pair would be (0, -2.3)
3. It is a y-intercept, so x=0. The ordered pair would be (0, 3/4)

To find the x-intercept, set y = 0. To find the y-intercept, set x=0

4. y-intercept: y = 3(0) -9. y = -9 The y-intercept is at (0, -9)
x-intercept: 0 = 3x -9. 9 = 3x. x = 3. The x-intercept is at (3, 0)

5. x intercept: 0 = 5x +10. -10 = 5x. x = -2. The x-intercept is at (-2, 0)
y-intercept: y = 5(0) + 10. y = 10. The y-intercept is at (0, 10)

If you look at finding the y-intercepts in the two problems above, you may see there is a pattern forming. The y-intercept is the number that your adding or subtracting that is located after the x (ex. y = 4x - 2 - the y-intercept would be -2)

9. First, find the x and y-intercepts. The y intercept is -3 You’d graph that at (0, -3). 0 = -1/2x - 3. -1/2x = 3. x = -6 so the x-intercept is at (-6, 0). If you only need to graph 2 points, then you can graph just those two points and draw a line between them.

To graph y=-1/2x + 3, start at the y-intercept and use the slope (-1/2) to find other points. Because your slope is -1/2, you’d go down 1 unit and then to the right 2 units. That would be your next point. If you wanted your line to go further up, go up one unit and then to the left 2 units. That would be your next point.

I am not sure what you need to do on 11 and 12

I think you should try 7, 8 and 10 on your own and let me know if you have any questions on them or if you are stuck on anything.

In a basketball game, Kyrie scored 5 less than twice as many as Steph. Combined the two scored 55 points. How many points did Ky
Aleonysh [2.5K]
Let steph score be x
Then kyrie score is 2x-5
Sum of the two scores is 55
Therefore x+2x-5=55
3x-5=55
3x=60
x=20

Therefore steph score is 20
And kyrie score is 2(20)-5
40-5=35

Three times the sum of n and four is twelve. write an equation or inequality.​
lisabon 2012 [21]

9514 1404 393

Answer:

  3(n+4) = 12

Step-by-step explanation:

The sum of n and 4 is (n+4). Three times that sum is 3(n+4). When we say it "is 12", we mean it is equal to 12.

  3(n +4) = 12
