Step-by-step explanation:
[tex]8x - 3 = 5 + 4y[/tex]
Isolate y first subtract 5 from both sides
[tex]8x - 8 = 4y[/tex]
Divide both sides by 4.
[tex] \frac{8x - 8}{4} = y[/tex]
[tex]2x - 2 = y[/tex]
y= 1
Step-by-step explanation:
Solve for y:
8x - 3 = 5 + 4y
8x = 4y + 5+3
Divide both sides by 8
x = 1÷2y + 1
plug into equation
8 (1÷2y +1) - 3 = 5 + 4y
Distribute
8÷2+ 8 - 3 = 5 + 4y
4 + 5 -5 = 4y
Combine like item
4 = 4y
divide both sides by 4
y= 1

what are the coordinates of the point (2,3) after a counterclockwise rotation of 90° about the origin? Only answer if your 100% right please. Will Mark Brainliest
(-3, 2)
Step-by-step explanation:
when the point is rotated through 90∘ about the origin in the counterclockwise direction then the point M(h,k) takes the image M′(−k,h)
so the point (2,3) will be (-3 ,2 )

The product of 7 and a number subtracted from 49 is 21. How do I write that as an equation?
Answer:
7x-49=21
Step-by-step explanation:
Express (16^3)^1/2
in simplest radical form.
Answer:
I assume you mean 16^(1/3) i.e. the cube root of 16
I am also assuming you mean the real cube root because, as you may know, every non-zero real number has three cube root - one real and two complex conjugates.
Since 16 = 8 x 2 and 8 = 2³ then (2³ x 2)^1/3 = (2³)^1/3 x 2^1/3 = 2 x 2^1/3
You might check that the cube root of 16 is about 2.52 which is twice the cube root of 2

Cody won 64 super bouncy balls playing hoops at the county fair. At school he gave three to every student in his math class. He only has 7 remaining. How many students are in his class ?
need algebraic equation too
QUICK! WILL AWARD BRAINLIEST!
Please solve the following five boxes.
Step-by-step explanation:
Set the equation
[tex](x - 4) {}^{2} [/tex]
swap y and x
[tex](y - 4) {}^{2} = x[/tex]
[tex]y - 4 = {x}^{2} [/tex]
[tex]y = {x}^{2} + 4[/tex]
So the inverse is
[tex] {x}^{2} + 4[/tex]
The domain is [4, infinity)
The range is [0,infinity)
The domain of the inverse is [0, infinity)
The range is [4, infinity)

Kollie was born in January
2000. How old wos he five
years ago?
Answer:
He was 16 years old.
Step-by-step explanation:
[tex] = (2021 - 5) - 2000 \\ = 2016 - 2000 \\ = 16[/tex]
Answer:
16 years old.
Step-by-step explanation:
Today's year is 2021
So,
[tex]2000 + 21 = 2021[/tex]
So, whoever's born in 2000, would be 21 years old in 2021. How old was Kollie five years ago?
[tex]21 - 5 = 16[/tex]
Kollie was 16 years old.
The sum of the speeds of two trains is 719.3 miles per hour. If the speed of the first train is 8.7 mph faster than that of the second train find the speeds of each.
What is the speed of the first train?
Answer:
First train 364, second train 355.3
Step-by-step explanation:
Let's me just say
First train = x
Second train = y
Easier to type like that
So
x + y = 719.3
they say " first train is 8.7 mph faster than that of the second train "
Therefore
x = y + 8.7
Now u have these two equations
x + y = 719.3
x = y + 8.7
Now since u know what is x, just put it in your first equation
x + y = 719.3
y + 8.7 + y= 719.3
2y = 710.6
= 355.3
Therefore the speed of the first train is
x + y = 719.3
x + 355.3 = 719.3
x =364

Answer:
Rs 3200
Step-by-step explanation:
The actual selling price was 20% below the cost price, so was ...
sp = cp(1 -20%) = 0.80cp
Had the selling price been raised, the selling price would have been 5% above the cost price:
sp +800 = cp(1 +5%) = 1.05cp
Subtracting the first equation from the second gives ...
(sp +800) -(sp) = (1.05cp) -(0.80cp)
800 = 0.25cp . . . . . . . simplify
3200 = cp . . . . . . . . multiply by 4
The cost price was Rs 3200.
The sum of two whole numbers is 64 and their difference is 20. What is the bigger number?
Answer:
42 and 22 are the numbers
Step-by-step explanation:
Let the numbers be x and y
[tex]x + y = 64[/tex]
[tex]x - y = 20[/tex]
On adding both
[tex]x + y + x - y = 64 + 20[/tex]
[tex]2x = 84[/tex]
[tex]x = \dfrac{84}{2} [/tex]
[tex]x = 42[/tex]
Using 1
[tex]42 + y = 64[/tex]
[tex]y = 64 - 42[/tex]
[tex]y = 22[/tex]
Match the expression to its value.
