Which point on the graph is the solution to the system of linear equations? -2x=-y+4 x=-2

Mathematics
1 answer:
Elodia [21]2 years ago
4 0

Answer:

The solution is (-2, 0)

Step-by-step explanation:

Re-write -2x=-y+4 x=-2 in column form:

x=-2

-2x=-y+4

Next, substitute -2 for x in the second equation:

-2(-2) = -y + 4, or:

4 = -y + 4.  Thus, y must be 0.

The solution is (-2, 0)

Find the equation of the straight line passing through the point (3,5) which is perpendicular to the line y=3x+2
Levart [38]

Answer:

the desired equation is y = (-1/3)x + 6

Step-by-step explanation:

Let the given line be A:  y=3x+2

The slope of line A is m = 3.

The slope of any line B which is perpendicular to line A is the negative reciprocal of the slope of A:  m = -(1/3).

The particular perpendicular line that passes through (3, 5) is then

5 = (-1/3)(3) + b, which simplifies to 5 = -1 + b, or b = 6.

Thus, the desired equation is y = (-1/3)x + 6

A car travels at constant speed for 7 days and covers 1500 miles. What is the speed in centimeters/minute? You may use the (appr
zvonat [6]

Answer:

Speed = 23809.52 cm/min      

Step-by-step explanation:

Given : A car travels at constant speed for 7 days and covers 1500 miles.

To find : What is the speed in centimeters/minute

Solution : Formula to find speed is

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

Distance traveled = 1500 miles and time taken = 7 days

\text{Speed}=\frac{\text{1500 miles}}{\text{7 days}}

Now, we have to convert miles into centimeter and days into minutes.

1 day = 24 hours

1 hour= 60 minute

24 hr= 24×60 minute

1 day =  24×60 minute

7 days = 7×24×60 minute = 10,080 minute

Now, 1 mile = 8/5 km = 1.6 km

1 km= 100000 cm

1.6 km = 1.6 × 100000 cm

1 mile = 1.6 × 100000 cm

1500 miles = 1500×1.6 × 100000 cm = 240,000,000 cm

Put back the values into speed

\text{Speed}=\frac{\text{1500 miles}}{\text{7 days}}

\text{Speed}=\frac{\text{240,000,000 cm}}{\text{10,080 minute}}

\text{Speed}=\text{23809.523 cm/minute}

Therefore, speed = 23809.52 cm/min
