Answer:

-1.6x2 + 2.3x + 3.2 = f(x) to solve this you do -1.6 x 2 = -3.2 + 2.3x = -0.9 + 3.2 = 2.3

Step-by-step explanation:

For A the height of ledge is 3.2

for b - the frogs highest point 2.30x

and c is 12.3x

Answer:

16=c

Answer:

x=2

Step-by-step explanation:

Let's solve your equation step-by-step.

Step 1: Simplify both sides of the equation.

12=2x+4x

12=(2x+4x)(Combine Like Terms)

12=6x

12=6x

Step 2: Flip the equation.

6x=12

Step 3: Divide both sides by 6. 6x/6=12/6

x=2

Hope you found this helpful and have good day (.

Answer:

2

Step-by-step explanation:

plus the like-terms (x plus x): 2+4

so 12=6x. get 6 out of the x-term. X is the unknown number being multiplied by 6. To get it to the other side, divide the numbers. So: 12/6=x and 12/6 is 2. so x=2.

Hello!

Answer:

The answer is C

Step-by-step explanation:

I wrote it in to my graphing calculator

Hope this helps!

Step-by-step explanation:

[tex]\tt{} \frac{3}{4} (x - 6) = 2(x - 3) + 4[/tex]

[tex]\tt{} \frac{3}{4} x - \frac{9}{2} = 2x - 6 + 4[/tex]

[tex]\tt{} \frac{3}{4} x - \frac{9}{2} = 2x - 2[/tex]

[tex]\tt{}3x - 18 = 8x - 8[/tex]

[tex]\tt{}3x - 18 = - 8 + 18[/tex]

[tex]\tt{} - 5x = 10[/tex]

[tex]\tt{}x = - 2 \\ \\ [/tex]

Answer:

x=-8

Step-by-step explanation:

3/4( x -16) = 2 ( x- 3) +4

3/4x - 3/4*16 = 2x - 6 + 4

3/4 x -12 =2x -2

-2x = -2x

________________

-5x/4 -12 = -2

+2 = +2

_____________

-5x/4 = 10

x=- 10*4/5

x= -8

Answer:

y=1

Step-by-step explanation:

You're correct also graphed so you can see your answer is right

The graph is undedefined because it doesn't have a X and continues straight on one point. So for standard for you would put Y=1/undefined or just undefined

Answer:

y=1/2x+14

Step-by-step explanation:

If you mark (-8,10) in a graph and go up 1, over 2, then you will eventually get to (0,14).

You can also use the slope formula in reverse. 1/2=b-10/0-(-8)

1/2=b-10/8, then multiply both side by 8

4=b-10, add 10 to both sides

14=b

Answer:

[tex]\frac{{5}}{w^{2}}[/tex]

Step-by-step explanation:

We begin with [tex]\frac{15w^{4}v^{5}}{3w^{6}v^{5}}[/tex].

Firstly, as with simplifying fractions we can simplify the numbers. 15 is divisible by 3, so this becomes [tex]\frac{5w^{4}v^{5}}{w^{6}v^{5}}[/tex].

To simplify indices (aka exponents or powers), we must subtract the power on the denominator from the matching one on the numerator, and then use that number as the power in the numerator. In this case, 4-6 and 5-5, which becomes -2 and 0.

So now we have [tex]\frac{5w^{-2}v^{0}}{1}[/tex].

For a negative power, we switch it into the other half (numerator to denominator) and take away the negative sign, leaving [tex]\frac{5v^{0}}{1w^{2}}[/tex].

We can remove the [tex]v^{0}[/tex] in the numerator as it just multiplies the numerator by one, and remove the 1 in the denominator for the same reason.

This leaves us with [tex]\frac{5}{w^{2}}[/tex].

This is because the data shows that for every 7 days the plant grows 7cm

The simple interest of a given sum is directly proportional to the rate of interest. The total amount for repayment is $979.43.

The simple interest is a method of calculating the interest over a sum without considering the compounding.

The simple interest over a period of time varies as arithmetic progression.

Given that,

The amount of loan P = $561.60

Time for the interest T = 8 years.

Rate of interest R = 9.3%.

The total amount A can be given by summing the amount of loan to the interest over it as,

A = P + S.I

And the simple interest is given as,

S.I = (P × R × T) / 100

    = (561.60 × 9.3 × 8) / 100

    = 417.83.

The amount is given as,

A = 561.60 + 417.83

   = 979.43.

Hence, the total amount to be repaid is $979.43.
