Express 5×-4y=20 in the form a×+by+c=0and write the value of a,band c<br><br>​
finlep [7]

Answer:

a = 5

b = -4

c = -20

Step-by-step explanation:

Here, we want to express the given equation in the following form;

So we can have this as;

5x-4y-20 = 0

That means we have;

a as 5

b as -4

and c as -20

For each rectangle below, write a linear equation that represents the area y of the rectangle. Solve this system of two linear e
Hatshy [7]

(5,24)

  • The two areas are the same.

  • To find the area, we multiply the side lengths. Y=area

Rectangle 1: side lengths 4 and (x+1)

y=4(x+1)= 4x+4

Rectangle 2: side lengths 3 and (2x-2)

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

  • Since the two areas are same, we can conclude that

4x+4=6x-6

  • Now, simplify.

-2x=-10, x=5

  • Since x is 5, we can plug it into the equations to find y.

Option 1 with rectangle 1: y=4(5)+4, y=24

Option 2 with rectangle 2: y=6(5)-5, y=24

I graphed the linear equation on desmos.

According to the National Beer Wholesalers Association, U.S. consumers 21 years and older consumed 26.9 gallons of beer and cide
motikmotik

Answer:

Kindly check explanation

Step-by-step explanation:

If the null is rejected, then we conclude that the average Consumption of beer and cider by customers who are 21 years and above is greater than 26.1

A type 1 error is committed if the null hypothesis is incorrectly rejected ; this means we will be concluding that customers who are 21 years and older have higher average Consumption when they actually do not. This may lead to a restriction on beer consumption in the city when there actually isn't a need for it.

For type 2 error, a false null is incorrectly accepted, in this scenario, we are saying that the consumption of beer and cider is not beyond the mean value when in actual sense it is.

( 4 over 4 )x = 4/32 what is the value of x
aksik [14]

4 over 4 (4/4) is equal to 1.

The equation can be rewritten as X = 4/32

4/32 can be simplified to 1/8


So you have X = 1/8

Axis of symmetry of f(x)=(x+3)^2-8
Anna007 [38]

<u>ANSWER</u>

x =  - 3

<u>EXPLANATION</u>

When a quadratic equation is in the vertex form,

f(x) = a {(x - h)}^{2}  + k

the equation of axis of symmetry is simply

x = h

The given quadratic equation is

f(x) =  {(x + 3)}^{2}  - 8

We can rewrite this as

f(x) =  {(x  -  -  3)}^{2}  - 8

We now compare to

f(x) = a {(x - h)}^{2}  + k

We have

h =  - 3 \:  \:  \: and \:  \: k =  - 8

Therefore equation of axis of symmetry is:

x =  - 3
