What does this mean? I don’t understand.

Answer:

it has two zeros because it is touching x axis two times

Answer:

h α t

h = kt

k = h/t

350 = k5

350/5 = k

k = 70

Step-by-step explanation:

Given that :

Ballon height varies directly as the Ascent time in minutes

Height of hot air Ballon rises 350 feets in 5 seconds

Expressing as a direct variation :

Let height of Ballon = h

Time it takes to rise = t

h α t

h = kt

k = h/t

350 = k5

350/5 = k

k = 70

Answer:

3x = 56 - (4x + 8)

Step-by-step explanation:

Let

Cost of peanut = x

Cost of Cashew = x + 2

Total Cost = Cost of Cashew + Cost of peanut

56 = (x+2) * 4 + x * 3

Cost of peanut: 3x = 56 - (4x + 8)

Total Cost = Cost of Cashew + Cost of peanut

56 = (x+2) * 4 + x * 3

56 = (4x + 8) + 3x

56 = 4x + 8 + 3x

56 = 7x + 8

56 - 8 = 7x

48 = 7x

x = 48/7

x = 6.86

Answer: 7.3

Step-by-step explanation:

Do the parentheses first!

4-7= -3

Then, multiply -3 by 2

-3×2= -6

Next,

-6-6.7= -12.7

Then, add -12.7 to 20

-12.7+20=7.3

Your answer is 7.3

Step-by-step explanation:

Force (F) = 450 N

Pressure (P) = 15 N/m² or 15 pa

Area (A) = ?

We know the force acting normally per unit area is pressure so,

P = F / A

15 = 450 / A

A = 450 / 15

A = 30 m²

The area to which the force has been applied is 30 m².

Step-by-step explanation:

Answer:

Multiply the bottom equation by -3/2 then add the equations.

Multiply the top equation by-3. then add the equations

Step-by-step explanation:

Given the simultaneous equation

2x- 6y=6  ... 1

6x - 4y = 2 ... 2

To eliminate a variable, we have to make the coefficient of one of the variable to be the same.

Multiply equastion 1 by -3

-6x+18y= -18  

6x - 4y = 2

Add the result:

-6x + 6x + 18y-4y = -18+2

18y-4y = -18+2

14y = -18

y = -9/7

Another way is to Multiply the bottom equation by -3/2 then add the equations.

Multiplying equation 2 by -3/2 will give;

6x(-3/2) - 4y(-3/2) = 2(-3/2)

-9x + 6y = -3

Add to equation 1;

2x- 6y=6

-9x + 2x + 0 = -3+6

-7x = 3

x = -3/7

Hence the correct two options are;

Multiply the bottom equation by -3/2 then add the equations.

Multiply the top equation by-3. then add the equations

Answer:

1/6

Answer:

14) [tex]f(10) = 10[/tex], 15) [tex]f(-2) = -2[/tex], 16) [tex]f(a) = a[/tex], 17) [tex]f(a+b) = a+b[/tex], 18) [tex]g(10) = 38[/tex], 19) [tex]g(-2) = -22[/tex], 20) [tex]g(a) = 5\cdot a - 12[/tex], 21) [tex]g(a+b) = 5\cdot a +5\cdot b -12[/tex]

Step-by-step explanation:

Let [tex]f(x) = x[/tex] and [tex]g(x) = 5\cdot x - 12[/tex], we proceed to resolve on each case:

14) [tex]f(10)[/tex]

[tex]f(x) = x[/tex]

[tex]f(10) = 10[/tex]

15) [tex]f(-2)[/tex]

[tex]f(x) = x[/tex]

[tex]f(-2) = -2[/tex]

16) [tex]f(a)[/tex]

[tex]f(x) = x[/tex]

[tex]f(a) = a[/tex]

17) [tex]f(a+b)[/tex]

[tex]f(x) = x[/tex]

[tex]f(a+b) = a+b[/tex]

18) [tex]g(10)[/tex]

[tex]g(x) = 5\cdot x - 12[/tex]

[tex]g(10) = 5\cdot (10) -12[/tex]

[tex]g(10) = 38[/tex]

19) [tex]g(-2)[/tex]

[tex]g(x) = 5\cdot x - 12[/tex]

[tex]g(-2) = 5\cdot (-2) -12[/tex]

[tex]g(-2) = -22[/tex]

20) [tex]g(a)[/tex]

[tex]g(x) = 5\cdot x - 12[/tex]

[tex]g(a) = 5\cdot a - 12[/tex]

21) [tex]g(a+b)[/tex]

[tex]g(x) = 5\cdot x - 12[/tex]

[tex]g(a+b) = 5\cdot (a+b) -12[/tex]

[tex]g(a+b) = 5\cdot a +5\cdot b -12[/tex]
