What value of x will make the equation below true?
5x = 12x – 28

Answers

Answer 1
x = 4
First take 12x off both sides, so -7x=-28
The negatives cancel out, so 7x=28
Not find the hcf and divide by that.
Answer 2

Answer:

3.4

Step-by-step explanation:

5x=12x-28

28=12x-5x

28=8x

28÷8=3.4

the answer is option 2

Answer:

Option 2

Step-by-step explanation:

Given function:

x=8 and y=6x=5 and y=20

Option 1: ×

Table one: y=8-6

if y is 6 then 8-6 can’t be 6 it is 2.

Option 2: √

Table one:

y=8-2

y would be 6 then this would be correct..

Table two:

y=4x

if y=20 then x would be 5 and if y is 16 then x=4.

Option 3:×

y=4x

this is wrong since table 2 is y=4x..

Option 4:×

Table one

y=x-4

if y is 6 and x is 8 then this is wrong..

Therefore, option 2 is correct..

Answer:

y=3x-3

Step-by-step explanation:

insert the first point into y=mx+b

3=2m+b

----------------

Do it again with the other point

6=3m+b

-------------

Now put both equations in a system of equations

3=2m+b

6=3m+b

solve for m and b

m=3 and b=-3

y=3x-3

m=slope

b=y-intercept

what is the distance between (0.-3) and (9.6)

Answers

Answer:

d = 12.7  when rounded to the nearest tenths

Step-by-step explanation:

Distance formula:

d=√((x_2-x_1)²+(y_2-y_1)²)

Your ordered pairs (0, -3) and (9, 6)

d=√((9-0)²+(6-(-3))²)

d=√((9))²+(6+3))²)

d=√(81 + (9)²)

d = √162

d = 12.727...

d = 12.7  when rounded to the nearest tenths
