Answer:
C. If an animal is a dog, then it is a golden retriever; false
Step-by-step explanation:
Logical reasoning is an important aspect of mathematics.
The conditional statements in the question are represented by the letters p and q. The if-then statement in which the statement p will lead to a conclusion in q is a glaring characteristic of conditional statements. A conditional will be held to be true unless a statement that is true has a false conclusion derived from it.
In the question above, the conditional statement is; If an animal is a dog, then it is a golden retriever. We can clearly see that this conclusion is false.
Consider this expression.
-3x2- 24x - 36
What expression is equivalent to the given expression?
Answer:
-3 2 6
Step-by-step explanation:
Consider this expression.
-3x2- 24x - 36
What expression is equivalent to the given expression?
-3 (x + 2)(x+6)
Drop down answer is in bold
The equivalent expression will be : - 3 (x + 2) (x + 6)
We have the following expression -
[tex]-3x^{2}[/tex] - 24x - 36
We have to find out the equivalent expression of above expression.
Expand the following expression - (x + 2)(x + 4).Above expression can be expanded in the following way -
(x + 2)(x + 4) = x(x + 2) + 4(x + 4) = [tex]x^{2}[/tex] + 2x + 4x + 16 = [tex]x^{2}[/tex] + 2x + 16
According to question -
[tex]-3x^{2}[/tex] - 24x - 36
- 3 ([tex]x^{2}[/tex] + 8x + 12)
-3 ([tex]x^{2}[/tex] + 6x + 2x + 12)
-3 [x(x + 6) + 2(x + 6)]
-3(x + 2)(x + 6)
Hence, the equivalent expression will be : -3(x + 2)(x + 6)

Answer:
k =-2
Step-by-step explanation:
Using the slope formula
( y2-y1)/(x2-x1) = m
( k- -1)/( -10 - -8) = 1/2
( k+1)/ ( -10+8) = 1/2
( k+1) /-2 = 1/2
Multiply each side by -2
( k+1) /-2 * -2 = 1/2 * -2
k+1 = -1
Subtract 1 from each side
k+1-1 = -1-1
k = -2
Answer:
K= -5 because -10 divided by -5 which is K gives u 2
On January 3rd, the Earth is 147,500,000 kilometers away from the Sun. On July 4th, the Earth is 152,500,000 kilometers away from the Sun. The Sun has a radius of about 865,000 kilometers.
Could the Earth's orbit be a circle with some point in the Sun as its center? Explain your reasoning.
Answer:
No
Step-by-step explanation:
It could not because in order for it to be a circle the number of kilometers would have to be constant, however in earth's orbit it is not constant, therefore it is an oval, not a circle.

A triangle has exactly three sides. Prove the conditional by proving the contrapositive. If a polygon has more than three sides, then it is not a triangle. Contrapositive: If _____, then _____. Since ______, the contrapositive is _____, the original statement must be _____.
Answer:
If a polygon is a triangle, then it has exactly three sides
Since as have been presented above, the contraposition is true, the original statement must be true
Step-by-step explanation:
The contrapositive statement; If a polygon has more than three sides, then it is not a triangle
We have that the definition of a triangle = A polygon with exactly three sides
Therefore;
A polygon with more than three sides is not a triangle and has (n - 1)/2×180 degrees interior angle, where n = The number of sides
Therefore, when n > 3, (n - 2)/2×180 > 180°
The sum of interior angles of a triangle = 180°
Therefore, the contrapositive statement, if a polygon has more than three sides, then it is not a triangle is true
Therefore, we have;
If a polygon is a triangle, then it has exactly three sides
Since as have been presented above, the contraposition is true, the original statement must be true

It’s asking to write an equation of the line with a slope...please help!!
Answer:
y = -3/4x - 6
Step-by-step explanation:
Use y-intercept (0, -6) and slope -3/4 and put into y=mx+b form to solve for b
Remember that m is also known as slope!
-6=(-3/4 * 0) + b
b= -6
y= -3/4x - 6

Answer:
[tex]\boxed {x = 19}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3x - 4 = 15 + 2x[/tex]
-Take [tex]2x[/tex] and subtract it from [tex]3x[/tex]:
[tex]3x - 4 - 2x = 15 + 2x - 2x[/tex]
[tex]x - 4 = 15[/tex]
-Add [tex]4[/tex] to both sides:
[tex]x - 4 + 4 = 15 + 4[/tex]
[tex]\boxed {x = 19}[/tex]
So, the value of [tex]x[/tex] is [tex]19[/tex].

Suppose y varies directly as x, and y = 21 when x = 3. Find x when y = 42.
Answer:
x = 24
Step-by-step explanation:
y₂ - y₁
42 - 21 = 21
x + 21
3 + 21 = 24
So when y increases by 21, so does x.
x = 24

What integers are closest to the square root of 54 on the number line?
Answer:
sqrt(54) is between 7 and 8
Step-by-step explanation:
Lets look at integers that are squared
1^2 = 1
2^2 = 2
3^2 = 9
4^2 = 16
5^2= 25
6^2 = 36
7^2 = 49
6^2 =64
54- 49 = 5 and 64 - 54 = 10
So 54 is closer to 49
so sqrt(54) is closer to the sqrt(49) = 7
sqrt(54) is between 7 and 8
