Step-by-step explanation:
What point is on both lines y=12x+3 and y=x+1
(no graph)
Step-by-step explanation:
by having two equations that have the same point, you can set the two equations equal to each other
y = 12x + 3, y = x + 1
12x + 3 = x + 1
11x = -2
x = -2/11
when you find the the x value, plug it back into either one of the equations
y = x + 1
y = (-2/11) + 1
y = 11/11 - 2/11
y = 9/11
the point (solution):
(-2/11, 9/11)
Answer:
(-2|11, 9|11)
Step-by-step explanation:

What is the equation of a line perpendicular to -x +2=y that intersects the line at (-1,5, 3,5)?
Answer:
B
Step-by-step explanation:
slope equals 1 and y-int equals 5
Planes A and B are shown. If a new line, p, is drawn parallel to line l, which
statement is true?
O Line p must be drawn in plane B.
O Line p must be perpendicular to line m.
O Line p must be drawn so that it can lie in the same plane as line l.
O Line p must be drawn in the same plane as line n
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.

============================================================
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.
Please help !!! I have no idea what I’m doing and can’t find anyone to teach me this
Answer:
The required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]
Step-by-step explanation:
In this question we need to find the equation of the graph in factored form.
The factored form will be: [tex]f(x)=a(x-r_1)(x-r_2)..[/tex]
where a is y-intercept and r₁, r₂ are x-intercepts
X-intercepts
When y=0, the values of x axis are known as x-intercepts
Y-intercepts
When x=0, the values of y-axis are known as y-intercepts.
Looking at the graph finding x-intercepts
When y=0 x=-2 and 1
So, we have
r₁ = -2
r₂ = 1
Looking at the graph finding y-intercepts
When x=0, y=-4
So, a = -4
Putting values in the formula we will get:
[tex]f(x)=a(x-r_1)(x-r_2)\\f(x)=-4(x-(-2))(x-1)\\f(x)=-4(x+2)(x-1)[/tex]
So, the required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

Kyle is buying a book online for $14.58. It is on sale for 10% off. What is the sale price with a 8.25% tax?
First, find the discount by finding 10% of $14.58. To do this, convert 0% into a decimal and multiply by $14.58.
14.58 x 0.1 = 1.458.
Since this a sale price, how much he is getting off, subtract from the total.
14.58 - 1.458 = 13.122.
We still have to find the sales tax. Solving is similar to finding the discount.
13.122 x 0.0825 = 1.082565.
Now, since it is a tax, add to the total.
13.122 + 1.082565 = 14.204565
Round to the nearest hundredth, and you have $14.20.
The sale price with after tax is $14.20.

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
