Is -5 a whole number, integer or a rational number ?
Answer:
-5 is an integer.
Step-by-step explanation:
Answer:
it is an integer
Step-by-step explanation:
It's and integer because a whole number goes up higher but never pass 0
an integer has whole numbers and their negative counterparts it would be a whole if it was just 5 and not -5 and it would be rational if it were -5.5
What is the prime factorization of 90?
====================================================
Explanation:
Divide by the smallest prime 2
90/2 = 45
Then divide by the next smallest prime 3 (since 2 won't go into 45)
45/3 = 15
Repeat the last step
15/3 = 5
We stop because the result is prime.
Note the denominators are 2, 3, 3. The final result is 5 which is prime.
So the prime factors are 2, 3, 3, and 5
They multiply to 2*3*3*5 = 90.
We can condense it to 2*3^2*5 = 90 because 3*3 = 3^2.
Answer and Step-by-step explanation:
The prime factorization of 90 is 2 × 3 × 3 × 5 or 2 × 32 × 5, where 2, 3, and 5 are the prime numbers. You can find "prime factorization" by following two simple steps. Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Step 2: Write the number as a product of prime numbers.

Step-by-step explanation:
J = Jimmys # of comics
J - 5 = Andrews # of comics
4J = Richards # of comics
6J - 5 = 145
+5 +5
6J = 150
divide by 6

y = x² – 3x – 8
y=2
How do I solve the equation?
Answer:
You use substitution
Step-by-step explanation:
Because you can see that y= both of those answers, you can set them equal to each other, creating the equation 2=x^2-3x-8
You then can use quadratics to solve the equation as follows:
-2 from both sides, 0=x^2-3x-10
Factors of -10 that add up to -3 are -5 and 2 leaving
0=(x-5)(x+2)
The 0 product property tells us that the answer is 5 and -2

Plot two points to form a square in the above graph.Label the points R and S. A square is a quadrilateral with all four sides of the same length. After plotting the points, trace the square by connecting the points.
PART B
To find the perimeter of a polygon, take the sum of the length of each side. What is the perimeter of the square that you created in part A? Round your answer to two decimal places.
Answer:
Perimeter = 28.84 m
Step-by-step explanation:
Since the other two points will make the shape to look like a square, each length of the square will be equal.
We can therefore find the length PQ by using the formula
L = sqrt ( [ X2 - X1 ]^2 + [ Y2 - Y1 ]^2
L = sqrt( [ -2 + 4 ]^2 + [ 4 + 3]^2
L = sqrt (4 + 49)
L = sqrt (52)
L = 7.2 m
Each length of the square is 7.2 m approximately
The parimeters will be:
Perimeter = 4L
Perimeter = 4 × 7.2
Perimeter = 28.84 metres
Therefore, the perimeter of the square is 28.84
Round o.oo9 to the nearest hundredth.
Answer:
0.01
Step-by-step explanation:
When rounding to the nearest hundredth, you look in the thousandths place to see if the number is 5 or greater. In this case it is. The hundredths place then moves up one number.

Solve for k.
6 + -4k = 18
k=
k=-3
6*(-4k)=18
subtract 6 from both sides
-4k=12
divide by -4 on both sides
k=-3
Answer:
[tex] \sf \: k = - 3[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of k.
The equation is,
→ 6 + (-4k) = 18
Then the value of k will be,
→ 6 + (-4k) = 18
→ 6 - 4k = 18
→ -4k = 18 - 6
→ -4k = 12
→ k = 12 ÷ (-4)
→ [ k = -3 ]
Hence, the value of k is -3.

-2(x+1)(x-2) what is the y-intercept?
Answer:
The y-intercept is at 4.
Step-by-step explanation:
When trying to find the y-intercept, you want to substitute your x's with 0 as x must equal 0 for your y-intercept. This gives you -2(0+1)(0-2). From here, you want to simplify your parenthesis equations.-2(1)(-2) Then you want to solve which gives you 4.

Answer:
Each side is 4 cm.
Step-by-step explanation:
We need to try to express the perimeter of the figure in terms of "square sides". Basically, we're going to count how many square sides the perimeter is.
Starting from the top, the very top is 1 side.
Moving down to the right, we have another side.
Then half a side as we go to the right edge.
The right edge is 1 full side.
Another half side, going left.
Going down, we have 1 full side.
The other side is mirrored, meaning we just have to double this to get the full figure's perimiter.
Counting up our sides (we'll call one side [tex]s[/tex] ), we have:
1s + 1s + 0.5s + 1s + 0.5s + 1s = 4s + 0.5s + 0.5s = 5s
Doubling it:
5s * 2 = 10s
The whole perimiter is 8 square sides. Since we know the perimeter is 40 cm, we can find the length of one side by solving this equation:
10s = 40
Dividing both sides by 10:
s = 40/10 = 4
Answer: Each side is 4 cm.

a. The same line
(Choice B)
Distinct parallel lines
(Choice C)
Perpendicular lines
(Choice D)
Intersecting, but not perpendicular lines
Answer:
C
Step-by-step explanation:
Both the given equations are of Perpendicular lines.
What are Perpendicular lines?Perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
Given are two equations of lines
y-2= x+20
y = x+20+2
y = x+22.....(i)
y-2= -(x+20)
y = -x-20+2
y = -x-18,,,,,,,(ii)
The slopes of the equation are 1 and -1, We know that perpendicular lines have slopes that are negative reciprocals of one another.
Hence, The lines given are perpendicular lines
