How to sole linear equations
slega [8]

Answer:

Step-by-step explanation:

I assume you mean simple linear equations, maybe not factoring. Anyhow Ill do a few examples:

1. 2x + 5 = 19

2. 14 - 3x = 23

3. 50x / 5 = 150

1. 2x + 5 = 19

Subtract 5

2x = 14

Divide by 2

x = 7

2. 14 - 3x = 23

Subtract 14 to the other side because we have to isolate the term with x in it

-3x = 9

Divide by -3

x = -3

3. 50x / 5 = 150

Multiply by 5 to isolate the value with x

50x = 750

Divide by 50

x = 15

I dont know if this is what you are looking for but this is general idea of how to solve these types of questions. If you need factoring or help with quadratics then let me know!

A hemispherical bowl is made of brass has an inner diameter 35 cm. What is the inner surface area? URGENT
Ganezh [65]

Answer:

The inner surface area of a hemispherical bowl will be: 1923.25 cm²

Step-by-step explanation:

Given

d = 35 cm

as

r=\frac{d}{2}

  =\frac{35}{2}

   = 17.5 cm

The inner surface area of a hemispherical bowl = 2πr²

=2\times 3.14\times \left(17.5\right)^2

=6.28\:\times \:17.5^2

=1923.25

Hence, the inner surface area of a hemispherical bowl will be: 1923.25 cm²

A car traveled at a constant speed. The graph shows how far the car traveled, in miles, during a given amount of time, in hours.
snow_tiger [21]

Answer:

Step-by-step explanation:

A car traveled at a constant speed as shown in the graph.

Distance traveled is on the y-axis and duration of travel on the x-axis.

Point A(3.5, 210) shows,

Distance traveled = 210 miles

Time to travel = 3.5 hours

So the point (3.5, 210) shows the distance traveled by the car in 3.5 hours is 210 miles.

Slope of the line = speed of the car = \frac{\text{Distance traveled}}{\text{Time}}

                           = \frac{210}{3.5}

                           = 60 mph

Now we will find the speed of the car at another point B(1, 60).

If the speed of car is same as the point B as of point A, point B will lie on the graph.

Speed of the car at B(1, 60) = \frac{\text{Distance traveled}}{\text{Time}}

                                             = \frac{60}{1}

                                             = 60 mph

Hence, we can say that point B(1, 60) lies on the graph.

What is the rate of change between the points (-3, 0) and (-2, -5)?​
Elis [28]

The rate of change is the change in Y over the change in X.

Rate of change =  (-5 - 0) / (-2 - -3)

Rate of change = (-5 ) / (-2+3)

Rate of change = -5 /1

Rate of change = -5
