Answer:

  23

Step-by-step explanation:

Let J represent Jiri's age. Then Pamela's age is 2J and the sum of their ages is ...

  J + 2J = 69

  3J = 69 . . . . .collect terms

  J = 23 . . . . . . divide by 3

Jiri's age is 23.

Write an equation in slope intercept form of the line that passes through the given point and is parallel to the graph of the gi
kupik [55]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following line:

y = 2x-8

The slope is m_ {1} = 2

By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to the given line will have a slopem_ {2} = 2

Therefore, the equation of the parallel line will be of the form:

y = 2x + b

We substitute the given point and find "b":

3 = 2 (-1) + b\\3 = -2 + b\\3 + 2 = b\\b = 5

Finally, the equation is:

y = 2x + 5

Answer:

y = 2x + 5

Using special products what is (wx-y)^2
VikaD [51]
I think that supposed to be (wx - y^2)^2?

If so, multiply using FOIL:

First: wx * wx = w^2x^2

Outside: wx * -y^2 = -wxy^2

Inside: -y * wx = -wxy^2

Last: -y^2 * -y^2 = y^4

Combine w^2x^2 - 2wxy^2 + y^4

I will make u a brainllest
Luba_88 [7]

Answer: d) q--->r

Step-by-step explanation:

This is an example of substitution.  We know that p=q, and need to make p=r.

Lets assume p=3.  Then q must equal 3.  Then r must equal three.  Thus, q=r.

If x=y and x=z then y=z

Can someone please explain this step by step on how to do it
luda_lava [24]
 addition factors of 44 equivalent to a ratio of 4:7
4*3= 12
7*3= 21
12+21= 32
4*4= 16
4*7= 28
28+16= 44
This is one of those things that you just have to do a bunch of calculations to eliminate and identify by deductive reasoning.
