Answer:

No solution.

Step-by-step explanation:

Step 1: Write equation

2x - 9 = 2x + 23

Step 2: Solve for x

Subtract 2x on both sides: -9 ≠ 23

Here, we can see that we would have no solution. Another way to see it is that these 2 lines are parallel, and parallel lines have no solution.

What are the slope and the y-intercept of the linear function that is represented by the table? X -1, -1/2, 0, 1/2 Y -3/2, 0. 3/

JulijaS [17]

Answer: Slope: 3, Y-intercept: 3/2

Step-by-step explanation:

x y

-1 -3/2

-1/2 0

0 3/2

1/2 3

Since we are given an x,y table, we can easily spot the y-intercept. The y-intercept has the x value of 0. Therefore, the y-intercept is 3/2.

Now, we can use the formula $m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$ to find the slope.

$m=\frac{\frac{3}{2} -0}{0-(-\frac{1}{2})}$

$m=\frac{\frac{3}{2} }{\frac{1}{2} } =\frac{3}{2} *2=3$

Slope: 3

Y-intercept: 3/2

The table shows the travelling time to work of 50 people.

Crank

Answer:

24.8 mins

Step-by-step explanation:

Time > timemark > frequency

0 – 10 > 10/2 = 5 > 5

10 – 20 > (10+20)/2 = 15 > 15

20 – 30 > (20+30)/2 = 25 > 13

30 – 40 > (30+40)/2 = 35 > 10

40 – 50 > (40+50)/2 = 45 > 7

The mean time for the 50 people is given by:

Mean = summation (mid time x frequency) / total frequency

Mean = [5x5 + 15x15 + 25x13 + 35x10 + 45x7] / 50

Mean = [25 + 225 + 325 + 350 + 315] / 50

Mean = 1240 / 50

Mean = 24.8 mins

Kamila [148]

Hi!!
The answer to your question is asking us to make an algerbraic equation for this situation.
H = 5V
Also, H + V = 52,000. H and V can then be solves by solving the 2 equations.
The results are 43,333 and 8,667

Plot the line for the equation on the graph. y-5=3/2(x-2)?

never [62]

Answer:

See the attachment

Step-by-step explanation:

The equation is in point-slope form, so you can read from the equation that one of the points on the graph is (2, 5).

The slope of 3/2 tells you that going 2 units to the right (to x=4) will move the point up 3 units (to y=8).

You can draw your line through these two points: (2, 5) and (4, 8).
