Answer:
c=-2
Step-by-step explanation:
Equation: -7c+2=16
-7c=16-2
-7c=14
c=14/-7
c=-2
Answer:
c = - 2
Step-by-step explanation:
Given
- 7c + 2 = 16 ( subtract 2 from both sides )
- 7c = 14 ( divide both sides by - 7 )
c = - 2

Answer:
The measure of angle A is:
m ∠ A = 53.13°
Step-by-step explanation:
Given
The length AC = 3 cm
The length BC = 4 cm
To determine
m ∠ A = ?
Using the trigonometric ratio
tan A = opposite / adjacent
From the right-angled triangle, as shown, it is clear that:
The opposite of m ∠ A is the side BC = 4 cmThe adjacent of m ∠ A is the side AC = 3 cmThus, substitute opposite = 4 and adjacent = 3
tan A = 4 / 3
A = arctan (4/3)
A = 53.13°
Therefore, the measure of angle A is:
m ∠ A = 53.13°
Prompt:
In unit 5 we have been talking about polynomials and their degree. Mr. McGill thinks the degree of this polynomial is 2 because it is the exponent in front. What mistake did Mr. McGill make and what should the correct answer be?
x2−6x12−4x+8
Answer:
degree of the polynomial should be 12
Step-by-step explanation:
The mistake he did was that he was supposed to consider the highest power
The power of the term in front should
not be used if the term does not have the highest power
As we can see. the term with the highest power is 12
So we can say that the degree is 12 and not 2

Which lines have a slope of -2?
Answer:
Line ALine BStep-by-step explanation:
When the problem is asking which lines have a slope of -2, this is referring to the steepness or rate of change. To determine which lines have a slope of -2, the line must have a rise of -2 and a run of 1. This means that the line will go down 2 units every 1 unit to the right.
Also, if a line is parallel (lines which never cross), it will have the same slope.
You can also eliminate lines c, and d because they increase while lines a, and b decrease. A and B have the same slope because they are parallel and decrease which means that this must be the answer.

Answer:
C. 42.57 and 42.58
Step-by-step explanation:
The best way is to go to a calculator and put in the numbers:
7√37 is 42.5793377121
So you simplify
42.5793377121
which is
42.58
Now you got your two numbers:
42.57 and 42.58
(If you rounded down you will result in 42.57)
So the answer is C. 42.57 and 42.58

Answer:
because SAS , NYC , PAC all are together
Step-by-step explanation:
The given statement in the question is SAS.
We are given that;
Trapezoid NYAP
Now,
Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
One possible given statement is that ∠NYC = ∠PAC.
This is because the base angles of an isosceles trapezoid are congruent. Since C is the midpoint of YA,
we know that YC = CA by the definition of midpoint.
Also, NC = CP is given.
by SAS, we can conclude that △NYC ≅ △PAC.
Therefore, by congruent triangles the answer will be SAS.

x=9
Answer:
x = 0.327
Step-by-step explanation:
[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7}[/tex] ÷ x
[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7}[/tex] × [tex]\frac{1}{x}[/tex]
[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7x}[/tex]
[tex]\frac{21}{4}[/tex] x 7x = 12
[tex]\frac{147x}{4}[/tex] = 12
147x = 12 x 4
x = 48 ÷ 147
x = 0.327

Answer: x > 5.
Step-by-step explanation:
The information given in the question can be expressed in an equation as:
Let the cost of each book be x
Cost of mug + Cost of books > 24
9 + (3 × x) > 24
9 + 3x > 24
3x > 24 - 9
3x > 15
x > 5.
Therefore, each book cost more than $5.
