Answer:

for 18 x is 6 and for 20 it is 11

Step-by-step explanation:

For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6

For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

Hope this helps :)

Answer:

18.) x = 6

20.) x = 11

Step-by-step explanation:

<em><u>18.)</u></em>

We know that line segments FC and ED are parallel to each other so they are congruent to each other:

-1 + 2x = 5 + x

-1 + x = 5

<u>x = 6</u>

<u><em>20.)</em></u>

We know that line segments DE and CF are parallel to each other so they are congruent to each other:

18 = -4 + 2x

22 = 2x

22/2 = x

<u>11 = x</u>

Hope this helps!

Which exponential function goes through the points (1, 16) and (4, 128)?
djyliett [7]

Answer:

Here is the complete question (attachment).

The function which represent the given points are f(x)=8(2)^{x}

Step-by-step explanation:

We know that a general exponential function is like,y=a(b)^{x}

We can find the answer by hit and trial method by plugging the values of (x,y) coordinates.

Here we are going to solve this with the above general formula.

So as the points are (1,16) then for x=1,\ y=16

Can be arranged in terms of the general equation.

ab^1=16...equation(1) and ab^4=128...equation(2)

a\times b=16, then\ a=\frac{16}{a}

Plugging the values in equation 2.

We have

\frac{16}{b} b^4=128,16\times b^3=128,b=\sqrt[3]{\frac{128}{16}} =\sqrt[3]{8}=2

Plugging b=2 in equation 1.

We have a=\frac{16}{b} =\frac{16}{2} =8

Comparing with the general equation of exponential a=8 and b=2

So the function which depicts the above points =y=8(2)^x

From theoption we have B as the correct answer.

total amount = P (1 + i)t What is the total amount that First Consumer Bank will receive after lending Jane $7,000 for three yea
Mazyrski [523]

F = final amount = unknown

P = 7000 is the principal (amount loaned)

i = 0.05 is the decimal form of 5% interest rate

t = 3 years go by

Plug those three values into the formula below and simplify

F = P*(1+i)^t

F = 7000*(1+0.05)^3

F = 7000*(1.05)^3

F = 7000*(1.157625)

F = 8103.375

F = 8103.38

<h3>Answer: Choice A) $8,103.38</h3>

Suppose your current electricity meter reading is 25,789 kWh, and the reading on your last bill was 25,350 kWh. If you are charg
Brrunno [24]

The amount of bill is $43.15

Step-by-step explanation:

Given,

Current meter reading = 25,789 kWh

Reading on last bill = 25,350 kWh

Reading for the month = Current meter reading - Last month bill reading

Reading for the month = 25789 - 25350 = 439kWh

Cost per kWh = $0.0983

Cost of 439 kWh = 0.0983*439 = $43.1537

Rounding off to nearest hundredth

Cost of 439 kWh = $43.15

The amount of bill is $43.15

3x-2y=-5 and 4x+2y=-16​
podryga [215]

Answer:

x=-22/4

y=-3

Step-by-step explanation:

3x-2y=-5

4x+2y=-16

we <u>add</u> the equation

7y=-21

y=-3

then we find the x by taking a random equation

I take 4x+2y=-16

4x+2(-3)=-16

4x-6=-16

4x=-22

x=-22/4
