Answer:
y = mx + b
because there is no number in front of the x we automatically assume the answer is 1
so the slope for the equation y = -x + 7 is -1
slope is -1
Step-by-step explanation:
if thats wrong then the slope is 1

12. Carla is lying on the ground between two trees in her backyard. She is 67 feet from the tree to her left. The angle of elevation from her eyes to the top of the tree on the left is 50°. Carla is 75 feet from the tree to her right and the angle of elevation from her eyes to the top of that tree is 36°. a. Determine the height of each tree to the nearest foot. Show your work. b. State which tree is taller, and by how much.
Answer:
the left tree is taller
Step-by-step explanation:
shown in work above :)
The first tree is taller than the second tree by 25.3 ft.
We have to use the trigonometric ratios and angle of elevation to obtain the height of each tree as follows;
Let the height of the first tree be h1 and the height of the second tree be h2.
For the first tree;
tan 50° = h1/67
h1 = 67 tan 50° = 79.8 ft
For the second tree;
tan 36° = h2/75
h2 = 75tan 36°
h2 = 54.5 ft
The first tree is taller than the second tree by 25.3 ft.

−6x+86−32x−12+52x
Enter your answer in the box.
Do not use decimals in your answer.
Answer: 14x+74
Step-by-step explanation:
-6x+86-32x-12+52x=14x+74
-6x+86-32x-12+52x
=-6x-32x+52x+86-12
=14x+86-12
=14x+74
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The final expression after simplifying is 14x + 74.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
3x + 4 = 3 is an expression.
3 + 4x - 5 is an expression.
We have,
-6x + 86 - 32x - 12 + 52x
Add like terms.

The point M is the midpoint of LN where M(-12, 6) and N (-2,-5).
What are the coordinates of point L?
Answer:
(-22,17)
Step-by-step explanation:
Finding X co-ord for L:
M=x2-x1/2
-12=x2-2/2
-24=x2-2
-22=x2
Finding Y co-ord for L:
M=y2-y1/2
6=y2-5/2
12=y2-5
17=y2
Compare and contrast the AA similarity criterion with the ASA congruence criterion. Choose the correct answer.
A. Both criteria require that two pairs of angles be congruent, but for congruence you also need to know that the included sides are congruent, so that the figures are the same size. The AA similarity criterion shows only that the two triangles are the same shape.
B. Both criteria require that two pairs of angles be congruent, but for congruence you also need to know that the non-included sides are congruent, so that the figures are the same size. The AA similarity criterion shows only that the two triangles are the same shape.
C. Both criteria require that two pairs of angles be congruent, but for congruence you also need to know that the included sides are congruent, so that the figures are the same size. The AA similarity criterion shows only that the two triangles are the same size.
D. Both criteria require that two pairs of sides be congruent, but for congruence you also need to know that the included angles are congruent, so that the figures are the same size. The AA similarity criterion shows only that the two triangles are the same shape.
Answer:
A
Step-by-step explanation:
Both criteria require that two pairs of angles be congruent, but for congruence, you also need to know that the included sides are congruent, so that the figures are the same size. The AA similarity criterion shows only that the two triangles are the same shape. Thus option A is correct.
What is AA similarity criterion?According to the Angle-Angle (AA) criterion, two triangle being considered comparable if "two angles from one triangle are equally equivalent to two angles of some other triangle."
According to the ASA congruence rule, two triangles are compatible when their two covered sides and two contained angles are equivalent to each other. However, thus according to AAS, if two triangles have two angles as well as one side that are identical to one another, then perhaps the triangles are congruent.
Because ASA and AAS are identical since it follows that if two images in one triangle are equal with two angles in another, therefore the third angles must likewise be identical. Therefore, option A is the correct option.

3. Which number is a natural number?
A-2.5
B 5-151
C-13+51
D|-81-2
Answer:
C
Step-by-step explanation:
A natural number is a number that you would use to count kids in a class for example. Like, 1,2,3,4 and so on. 2.5 is not a natural number since there cant be 2.5 of a student. 5-151 is a negative number and there cant be negative students. -13+51=38. 38 is a natural number. Now, in D it looks like there mightve been a absolute value sign but im not sure. If D has absolute value signs then D works too. Hope I could help.
