-2x + (1/2)y = 18

(1/2)y = 2x + 18

y/2 = 2x + 18

y = 2*(2x + 18)

y = 2*2x + 2*18

y = 4x + 36

The x intercept is the value of x, when the y value is 0.

0 = 4x + 36

0 - 4x = 36

-4x = 36

x = 36/-4

x = -9

The x intercept is  -9

I hope this helps.

Answer:

The x-intercept of the line with the equation is -9.              

Step-by-step explanation:

Given : Equation -2x+\frac{1}{2}y=18

To find : What is the x-intercept of the line with the equation ?

Solution :

To find x-intercept we put y=0.

Equation -2x+\frac{1}{2}y=18 substitute y=0,

-2x+\frac{1}{2}(0)=18

-2x=18

x=\frac{18}{-2}

x=-9

Therefore, The x-intercept of the line with the equation is -9.

Option D: \frac{2}{5} is the x-coordinate

Explanation:

It is given that the coordinates of the line segment are A(3,2) and B(6,11).

Since, the line is partitioned by the point C by the ratio AC : BC = 2 : 3

The distance between the x-coordinates is 3 units.

To determine the value of the x-coordinate for point C, let us divide the value of x-coordinate from the ratio divided by the sum of ratio.

The value of x-coordinate from the ratio is 2.

Sum of the ratio is 2 +3 = 5

Thus,

The x - coordinate = value of x-coordinate from the ratio / Sum of ratio = 2/5

Substituting the values, we have,

The x - coordinate of the Point C = \frac{2}{5}

Thus, Option D is the correct answer.

Two bicyclists are 7/8 of the way through a mile long tunnel when a train approaches the closer end at 40 mph. The riders take o
Anastaziya [24]

Answer:

the cyclists rode at 35 mph

Step-by-step explanation:

Assuming that the cyclists stopped, and accelerated instantaneously at the same speed than before but in opposite direction , then

distance= speed*time

since the cyclists and the train reaches the end of the tunnel at the same time and denoting L as the length of the tunnel :

time = distance covered by cyclists / speed of cyclists = distance covered by train / speed of the train

thus denoting v as the speed of the cyclists :

7/8*L / v = L / 40 mph

v = 7/8 * 40 mph = 35 mph

v= 35 mph

thus the cyclists rode at 35 mph

Mkey [24]

Answer:

178251.203502

Step-by-step explanation:

We have given:

Principal amount which is 80,000

Time which is 20 year

Rate which is 11.5%

And since, we have to find 13 years early so, time would be: 20-13=7 years.

And since, we have to find for 12 months

Hence, n=12

We have formula to calculate compound interest:

P{1+\frac{r}{n}}^{nt}

On substituting the values we get:

80,000(1+\frac{0.115}{12})^{12\cdot 7}

\Rightarrow 80,000(1+(\frac{.115}{12}})^{84}

On simplification we get:

178251.203502
