Answers
Answer:
-6
Step-by-step explanation:
First you need to substitute -1 in for x in -2x^2
This makes it (-2)(-1)^2
-2x^2 becomes -2 so this means that the equation is now
-2 + (-1) - 3
-2 + (-1) = -3
-3 - 3 = -6

Answers
Answer:
7. m<RST = 138°
8. m<MNP = 56°
9. m<WXZ = 130°
10. m<ABC = 118°
Step-by-step explanation:
7. m<RST = 138° (alternate exterior angles are congruent)
8. m<MNP = (a + 28)°
(a + 28)° = 2a° (alternate interior angles are congruent)
a + 28 = 2a
Collect like terms
28 = 2a - a
28 = a
m<MNP = (a + 28)°
Substitute a = 28
m<MNP = (28 + 28)° = 56°
9. m<WXZ = 5y°
5y = (2y + 78)° (alternate interior angles are congruent)
5y = 2y + 78
Collect like terms
5y - 2y = 78
3y = 78
Divide both sides by 3
y = 26
m<WXZ = 5y°
Plug in the value of y
m<WXZ = 5(26)
m<WXZ = 130°
10. m<ABC = (3n - 47)°
(3n - 47)° + (n + 7)° = 180° (same side interior angles are supplementary)
3n - 47 + n + 7 = 180
Collect like terms
4n - 40 = 180
Add 40 to both sides
4n = 180 + 40
4n = 220
Divide both sides by 4
4n/4 = 220/4
n = 55
m<ABC = (3n - 47)°
Plug in the value of n
m<ABC = 3(55) - 47 = 165 - 47
m<ABC = 118°

Here is a table of the average distance and the variation in the distance for the five innermost planets in our solar system: Average Distance and Variation Planet Name Average Distance Variation Mercury 36.0 million miles 7.39 million miles Venus 67.2 million miles 0.43 million miles Earth 93.0 million miles 1.55 million miles Mars 142 million miles 13.2 million miles Jupiter 484 million miles 23.2 million miles "Average distance" means the mean distance that planet is from the sun over the course of its orbit, and "variation" means how far it varies from that mean. For example, if a planet had an average distance of 5 miles and a variation of one mile, it would have distances between 4 and 6 miles at different times. a) Write and solve an inequality to represent the range of distances that can occur between the Sun and one of the planets from the table (your choice). Show your steps/process. b) Why is this best represented as an inequality rather than an equation? Explain in at least 3 sentences.

Answer:
a) |e-93|≤1.55; 91.45 ≤ e ≤ 94.55
b) see below
Step-by-step explanation:
a) Let e represent the distance from the sun to the earth in millions of miles. The table tells us the average distance is 93.0 million miles, and the difference from that value can be as much as 1.55 million miles. The corresponding inequality is ...
|e-93.0| ≤ 1.55
We can solve this by rewriting it as a compound inequality.
-1.55 ≤ e -93.0 ≤ 1.55
91.45 ≤ e ≤ 94.55 . . . . . . add 93

b) An absolute value equation will give a finite number of particular values as its solution. The question asks for a range of values. An absolute value inequality is well-suited to providing a solution that is a range of values.

Answers
Answer:

Step-by-step explanation:
Ok, so congruent means the same.
Using this knowledge, we can clearly see that the bottom pair are not congruent.
For the first pair, let compare the slopes and lengths of the line segments.
(If you have wax paper, you can trace A and see if it matches B)
GH <=> PQ = 2 blocks
LG <=> UP = 5/1 slope
KL <=> TU = 2 blocks
JK <=> ST = 1 block
IJ <=> RS = 1/1 slope
HI <=> QR =3 blocks
As you can see, all the corresponding side lengths/ slopes are the same.
This means the first pair are congruent.
help asappppp? i’m having trouble on wat the 1/4 point is
Answers
Answer:
(-14, 5.5)
Step-by-step explanation:
Perhaps the easiest way to find the 1/4 point is to find (x, y), then find the midpoint between that and M.
(x, y) = 2M -(13, 25) = 2(-5, 12) -(13, 25) = (-23, -1)
Then the 1/4 point is ...
((-23, -1) +M)/2 = ((-23, -1) +(-5, 12))/2 = (-28, 11)/2 = (-14, 5.5)
_____
If we call the end points A(x, y) and B(13, 25), then we know ...
M = (A+B)/2
A = 2M -B . . . . we'll need this in a bit
and the 1/4 point Q is such that ...
(Q -A)/(B -A) = 1/4
4Q -4A = B -A . . . . cross multipliy
Q = (B +3A)/4 = (B +3(2M -B))/4 = (6M -2B)/4 . . . . solve for Q
Q = (3M -B)/2 . . . . reduce the fractions
Q = (3(-5, 12) -(13, 25))/2 = (-28, 11)/2 = (-14, 5.5) . . . as above

Answers
Answer:
Approximately 23 cups of coffee
Step-by-step explanation:
Break even = Fixed cost/Selling price - variable cost
Fixed cost = $75
Selling price = $4.50
Variable cost = $1.25
Break even = $75/$4.50 - $1.25
= 23.076923077
Approximately = 23
