Answer:
y=3 x=4
Step-by-step explanation:
4x - 2y = 10
<u>4x + y = 19</u>
-3y=-9
the 4x canceled out.
y=3
plug in y into one of the equations
4x + 3 = 19
4x=16
x=4
Hope this helps!
If not, I am sorry.
Answer:
(8, 5)
Step-by-step explanation:
Let's take a look at the y-intercept, (0, 5). If the axis of symmetry is x = 4, then the distance from (0, 5) is 4 units. If we reflect this point (0, 5) about the axis of symmetry x = 4, the resulting point is (8, 5). In other words, the distance from the y-intercept to the axis of symmetry is 4 units, and so the distance from the y-intercept must be 4 units plus 4 units, or 8 units.
The only answer choice that matches this is the second one: (8, 5).

Answer:
AB = AD = 22 units
Explanation:
1- solving for r:
We are given that:
AD is congruent to AB
This means that:
AD = AB
2r + 8 = 5r - 13
5r - 2r = 8 + 13
3r = 21
r = 21/3
r = 7
2- getting the value of AB:
Since we calculated the value of r, we can simply substitute in the equation to get AB as follows:
AB = AD = 5(7)-13 = 2(7)+8 = 22 units
Hope this helps :)
Patrick completes 13 questions every 52 minutes.
We're trying to find the time for Patrick to complete 1 packet.
Let's set these up as a fraction equation.
13/52 = 1/x, x being the variable that substitutes the time we're looking for.
13/52 can be simplified, though.
Divide both numbers by 13.
13 / 13 = 1
52 / 13 = 4
We now have:
1/4 = 1/x.
Well, this makes it easier. The numerators match, so the denominators must match as well.
x = 4.
It will take Patrick 4 minutes to complete 1 homework question.
I hope this helps!
