Answer:
Step-by-step explanation: First, let's call the starting elevation of the plane: e
We can then write an equation representing this problem as:
e−1.5mi=5.25mi
Now, add 1.5mi to each side of the equation to solve for e
while keeping the equation balanced:
e−1.5mi + 1.5mi=5.25mi + 1.5mi
e−0=6.75mi
e=6.75mi
The plane's starting elevation was 6.75 miles

9514 1404 393
Answer:
[tex]f^{-1}(x)=\pm\sqrt{x-10}[/tex]
Step-by-step explanation:
You can find the inverse of
y = f(x)
by solving for y:
x = f(y)
__
x = y² +10
x -10 = y² . . . . . . . . subtract 10
±√(x -10) = y . . . . . take the square root
The inverse relation is ...
[tex]\boxed{f^{-1}(x)=\pm\sqrt{x-10}}[/tex]
__
It is not a function unless some restriction is placed on the domain of f(x).

3. In a triangle, two angles have measures of 45°
and 85. What is the measure of the third angle in
this triangle?
Answer:
Triangles always have 180°, split in some manner between the three angles. With two of the three angles given, you can set up a relatively simple equation, where the third angle is assigned to the variable x:
45°+85°+x=180°
130°+x=180°
x=50°

solve and graph: 7x-6>22
(pls explain your answer, im confused on this)
Answer:
x>4
Step-by-step explanation:
Solving an inequality is very similar to solving an equation:
Given: 7x-6>22
Add 6 to both sides: 7x>28
Divide both side by 7: x>4
x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

PLEASE HELP ME!!! Find m (angle) LMN
Answer:
108°
Step-by-step explanation:
hii!
lmn would be equal to 85 plus 23.
this is because those angles both make up the big angle lmn, so the answer is 108 degrees.
hope this helped you :)
m[tex]\angle{LMN[/tex] is 108°.
What is an angle ?To form an angle we need at least two rays with one common endpoint this is also known as vertex of the angle.
There are many types of angles.For example - Acute angle, Obtuse angle, Right angle, complementary angle, Supplementary angle.
The most common unit for measuring an angle is in degrees and in radians,Where 1 rad = 180°.
According to the given question.
[tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex] are given they are 85° and 23° respectively.
From the given diagram we can observe that [tex]\angle{LMN[/tex] is sum of the angles [tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex].
∴ [tex]\angle{LMP[/tex] + [tex]\angle{PMN[/tex] = [tex]\angle{LMN[/tex]
85° + 23° = 108°.
So, [tex]\angle{LMN[/tex] = 108°.

explain why 2+x and x+3 are equivalent
Check whether the two expressions 2x+3y2x+3y and 2y+3x2y+3x equivalent.
The first expression is the sum of 2x2x 's and 3y3y 's whereas the second one is the sum of 3x3x 's and 2y2y 's.
Let us evaluate the expressions for some values of xx and yy . Take x=0x=0 and y=1y=1 .
2(0)+3(1)=0+3=32(1)+3(0)=2+0=22(0)+3(1)=0+3=32(1)+3(0)=2+0=2
So, there is at least one pair of values of the variables for which the two expressions are not the same.

How many onto functions are there from a set with three elements to a set with eight elements?
Answer:
0 onto functions
Step-by-step explanation:
Let the sets be [tex]A\ and\ B[/tex] such that:
[tex]n(A) = 3[/tex]
[tex]n(B) = 8[/tex]
Required
The number of onto functions
The condition for onto functions is:
For there to be an onto function from set A to set B, the number of elements of B must be less than the elements in set A
Since n(B) > n(A) i.e. 8 > 3
Then, there can't be onto functions from A to B
