Y=21.95x+10 y=22.45x Solve by substitution

Mathematics
1 answer:
bogdanovich [222]3 years ago
4 0

Answer:

  (x, y) = (20, 449)

Step-by-step explanation:

When the equations are in this form, it is easiest to substitute one of the expressions for y into the other equation. That gives ...

  21.95x +10 = 22.45x

  10 = 0.50x . . . . . subtract 21.95x

  20 = x . . . . . . . . .multiply by 2

  y = 22.45x = 22.45·20 = 449

Lisa [10]

Answer:

Below.

Step-by-step explanation:

Number is different to the other 2. Its value is +4 because negative 2 squared = + 4.

What is the y-intercept of the line?<br><br> x 16 24 32<br> y 44 64 84
Shtirlitz [24]

Answer:

The y-intercept of the line is 2

Step-by-step explanation:

You could try to find the slope of the line and then find the intercept with y axis by sloving b = y - ax

But here it seems easy enough once you see that the x values in the table increase by a factor of 8 and the y values in the table increase by a factor of 20.

(By the way, this is enough to give you the slope, because it is 8/20 ). But why bother?

Just extrapolate the table to the left, and you will find the y value where x = 0

x 0 8 16 24 32

y 2 22 44 64 84

So the y-intercept of the line is 2.

Extra:

The full equation of the line is:

y = 8/20x + 2

KL = 4x +3.<br> JK = 4x + 2, and<br> JL = 45<br> Find KL.
lbvjy [14]

Answer:

KL=23

Step-by-step explanation:

We are given the length of the whole line and its two halves. Since JK and KL make up the line JL, adding them together would make the line JL.

(4x+3)+(4x+2) = 45

8x+5=45

8x=40

x=5

Now we can plug the value of x back into the expression we were given for the line KL.

4(5)+3

23
