Answer:
y=10 when x=7
Step-by-step explanation:
y=2x-4
y=10
Substitute y with "10": 10=2x-4
Add 4 on both sides: 14=2x
x=7
Answer:
substitute 10 for y in the equation y=2x-4
10=2x-4
2x=10+4
2x=6
divide both side by 2
x=3

Answers
Answer: the second one
Step-by-step explanation:
I’m smart I have al a’s
The true statement is - Line p must be drawn so that it can lie in the same plane as line l.
What is plane?"It is a two-dimensional flat surface with no edges or thickness."
What are parallel lines?"Two lines in the same plane that are at equal distance from each other and never meet."
For given question,
Planes A and B are shown.
If a new line, p, is drawn parallel to line l, must be drawn so that it can lie in the same plane as line l.
Line l lie in plane A.
So, the line p must be drawn in the plane A.
Therefore, the true statement is - Line p must be drawn so that it can lie in the same plane as line l.

Answer:
1. x < -2
2. x < -9
Step-by-step explanation:
1. x + 15 < 13
Minus 15 on both sides.
x + 15 - 15 < 13 - 15
+15 - 15 makes a 0.
x < -2
2. x + 11 < 2
Minus 11 on both sides.
x + 11 - 11 < 2 - 11
+11 - 11 makes a 0.
x < -9
Answer:
1. x < -2
2. x < -9
3. x < 15
Step-by-step explanation:
Treat the < and > symbols as an equals sign to make it less confusing to solve. Then solve for x like you normally would.
1. x+ 15 = 13
subtract 15 from both sides
x=-2, or x < -2
2. x + 11 = 2
Subtract 11 from both sides.
x=-9, or x <-9
3. 19 > x + 4
19 = x + 4
Subtract 4.
15 > x, or x < 15
Claudia spends $2.15 day for lunch.Her cafeteria lunch account has a balance of 48.00.Which equation can be used to determine the maximum number of days,d,that she can eat without adding money to her lunch account?
Answers
Given :
Claudia spends $2.15 day for lunch.
Her cafeteria lunch account has a balance of 48.00 .
To Find :
The maximum number of days, d that she can eat without adding money to her lunch account.
Solution :
Number of days she can eat without adding money in her account is :
[tex]n = \dfrac{Remaining \ Balance }{2.15}\\\\n = \dfrac{48}{2.15}\\\\n = 22.325[/tex]
But, number of days cannot be in decimal.
Therefore, maximum number of days she can eat without adding money to her lunch is 22 days.

============================================================
Explanation:
Let's find the slope of the table. This will tell us the rate of change.
m = slope
m = (y2-y1)/(x2-x1)
m = (25250 - 26375)/(2 - 1) .... I used the first two rows
m = -1125/1
m = -1125
The slope of -1125 means the plane's altitude is decreasing at a rate of 1125 feet per minute. This is the descent speed.
Since we're told the initial altitude was 27500 ft, this means b = 27500
This means y = mx+b turns into y = -1125x+27500
x is the number of minutes and y is the altitude at time x
As a way to check this, plug in various x values of the table. You should get corresponding y values that match the table. I'll let you do this part.
------------------
Now plug in y = 16250 and solve for x
y = -1125x+27500
16250 = -1125x+27500
-1125x+27500 = 16250
-1125x = 16250-27500
-1125x = -11250
x = -11250/(-1125)
x = 10
It takes 10 minutes after the descent period has started, for the pilot to get to 16,250 ft.
Since the pilot was contacted at the x = 4 minute mark, this means 10-4 = 6 minutes is the duration needed for the pilot to go from 23,000 ft to 16,250 ft.

Answers
Answer:
B, C, D, F
Step-by-step explanation:
to simplify the fraction 48/64, you need to divide both the numerator and denominator by their common factors. B is correct since you can divide both by 16, C is correct since both are divisible by 8, D is correct since both are divisible by 4, and F is correct since both are divisible by 2. A, however, would be correct only if the fraction were 64/48 and E would only be correct if 9 was a factor of 48 and 12 was a factor of 64, however neither haev such factors.
