Answer:
A
Step-by-step explanation:
For the function y = f(x), a reflection in the y axis is y= f(-x)
(-x)^3 = -x^3 so negate that term
(-x)^2 = x^2 so leave that as is
(-x)^1 = -x so negate that term too

At Norman's Newsstand, 5 magazines cost $20.00. How many magazines could you buy with $44.00?
Answer: 11 magazines
Step-by-step explanation:
1) 20/5 = $4 per magazine
2) 44/4 = 11 magazines
Answer:
10 magazines
Step-by-step explanation:
5 magazines cost $20.00
You have $44.00
If 5 magazines cost $20.00
Then 10 magazines would cost $40.00
Since the maximum amount of money you can spend is $44.00, you can only buy 10 magazines for $40.00 and be left with $4.00.

Step-by-step explanation:
step 1. m: m is the variable, 1 is the coefficient, 1 is the degree, constant is 0.
step 2. 3t^2 +4t - 6: t is the variable, 3 and 4 are the coefficients, 2 is the degree, -6 is the constant.
step 3. 2 - h: h is the variable, -1 is the coefficient, 1 is the degree (highest variable exponent), the constant is 2.
step 4. -7a^2: a is the variable, -7 is the coefficient (before the variable), 2 is the degree, the constant is 0.

Answer:
Step-by-step explanation:
Determine the length of AC and DE, and the value of x.
Answer:
n = 16, AC = 60, DE = 30
Step-by-step explanation:
DE joins the midpoints of 2 sides of the triangle and is half the length of the third side, that is
DE = [tex]\frac{1}{2}[/tex] AC , substitute values
n + 14 = [tex]\frac{1}{2}[/tex] (3n + 12) ← multiply both sides by 2 to clear the fraction
2n + 28 = 3n + 12 ( subtract 2n from both sides )
28 = n + 12 ( subtract 12 from both sides )
16 = n
Then
AC = 3n + 12 = 3(16) + 12 = 48 + 12 = 60
DE = n + 14 = 16 + 14 = 30

which equation would be the easiest to solve first by using the substitution method? EXPLAIN WHY
equation 1: 3x+5y= -8
equation 2: x- 2y=1
Answer:
Equation 2: x - 2y = 1
Step-by-step explanation:
The equations easiest to use substitution are the ones that have the variable multiplied by one, as in the case of Eq. 2 where x is 1x, so if you substitute a zero for x, we know that y has to be -1/2 for the equation to be true. Furthermore, if you substitute a 0 for y you automatically know that x = 1.
If you try to substitute anything for x in equation 1, let's say x = 1, you still have to multipy by 3, then the rest of the problem would be more steps.

The diagram shows a right angled triangle.
The length of the base of the triangle is 2 square root 3 cm. the length of the hypotenuse of the triangle is 6cm. The area of the triangle is A cm squared.
Show that A = k square root 2 giving the value of k.
Answer:
6 root 2
Step-by-step explanation:
Pythagous Therom
A^2 = B^2 + C^2
B^2 = C^2 - A^2
B^2 = 36 - (2 Root 3)^2
B^2 = 24
B = 2 root 6
Base x Height / 2 for area of Triangle
2 root 3 x root 24 = 12 root 2
12 root 2 / 2 = 6 root 2
The right triangle is the one where one of the angles is a right angle (90 degrees) or two of the sides are perpendicular.
Finding the value of k:The right-angled triangle is one where one of the angles is equal to 90°. The sum of the other 2 aspects is 90°. The perpendicular and the base of the triangle are indeed the sides that include the right angle. The hypotenuse, which would be the longest of the three sides, is the third side.In [tex]\Delta[/tex] ABC
h² = 6² -(2√3)²
h² = 36-2² × √3²
h² = 36- 4× 3
h² = 36- 12
h² = 24
h =√24
h = 2√6 cm
Area = [tex]\frac{1}{2}[/tex]× BC × h
= [tex]\frac{1}{2}[/tex] × 2√3 × 2√6
= 2√18
= 6√2
compare it with A= K√2 So K= 6

Answer:
10 for x and y
Step-by-step explanation:
Because the triangle adds up to 30 deggrees
So... you want to take 4 out.
30- 4 = 24
Than...You want to divided 24 by 2.
And that equals 12
Than round 12's by tenth
Which equals 10

What's substitution for y=4x-1, 2x+y=5
Step-by-step explanation:
y = 4x-1
2x+y = 5
2x+(4x-1) = 5
6x - 1 = 5
6x = 6
x = 1
Answer:
(1,3)
Step-by-step explanation:
Since we already have the variable to it self, we can substitute y=4x-1 into 2x+y=5.
So it would be 2x+(4x-1)=5
Remove the parentheses
Combine like terms
Move the constant to the right
Divide 6 on both sides to get the variable by it self.
x=1
Then we substitute x=1 into y=4x-1, so..
y=4(1)-1
y=4-1
y=3
So the answer would be (1,3).

Which set of side lengths cannot form a triangle? (screen shot attached)
Answer:
7in, 7in, and 15 in
Step-by-step explanation:
Based on the Triangle Inequality Theorem that states that the sum of any 2 sides of a triangle must be greater than the measure of the third side, we can find what set of lengths cannot form a triangle.
The only set that does not follow the theorem is the set with lengths 7in, 7in, and 15in. It does not follow the theorem because...
7 + 7 < 15 (which should not be true based on the theorem)
