Answer:

1. m=-8 or m=8

2. x=-3 or x=3

3. equation has no roots

(thus if represented in graph format, the graph will not

intersect the x-axis)

4. s=-√12 or s=√12

5. x=0 or x=4

Step-by-step explanation:

for questions 1, 2 and 4, nite that when there is an even power of a variable in an equation, there will be an introduction of extra solutions thus you cannot just assume that the numbers attained will always be positive as the multiplication if negative numbers will also give you a positive answer especially when you square the number.

To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the formula F= (C*1.8) + 32 where F is degrees
asambeis [7]

Answer:

The temperature is 50^{\circ}F

Step-by-step explanation:

Given

F= (C*1.8) + 32

Required

Find F when C = 10

F= (C*1.8) + 32

Substitute 10 for C

F = 10 * 1.8 + 32

F = 18 + 32

F = 50

Against the wind a commercial airline in South America flew 630 miles in 3.5 hours. With a tailwind the return trip took 3 hours
Salsk061 [2.6K]

Answer:

The speed of plane is 195\ mph, and speed wind is 15\ mph.

Step-by-step explanation:

Given against the wind the airline flew 630 miles in 3.5 hours.

including the tailwind the return trip took 3 hours.

Let speed of plane is x.

Also, speed of the wind is y.

Now, we will find speed on each case.

Speed against the wind is  \frac{630}{3.5}=180\ mph

Speed with the wind is \frac{630}{3}=210\ mph

Now, we will write the equation

x+y=210\\x-y=180

Add these equation we get,

2x=390\\x=\frac{390}{2}\\x=195\ mph

Now, plug this value in x+y=210 to get speed of wind

195+y=210\\y=210-195\\y=15\ mph

So, the speed of plane in still air is 195\ mph, and speed of the wind is 15\ mph.
