9y2 and 9y
like terms or unlike terms
Answer:
unlike terms
Step-by-step explanation:
since the first 9y is squared they cannot be combined since the other isn't squared, they cannot be simplified, nor are they alike
Kristin has 4 more headbands than Nikki does. Together they have 30 headbands. The equation h + (h+ 4) = 30 can be used to
determine the number of headbands each girl has. What part of the equation represents the number of headbands Kristin has?
A:h
B:h+4
C:4
D:30
Answer:
A) H+4
Step-by-step explanation:
I do this in a different way, but i'll do it in both
Mine:
30 ÷ 2 = 15
4 ÷ 2 = 2
15+2, 15 -2
17, 13
Kristen Has 17
Yours:
h+(h+4)=30
-4 -4
h+h = 26
2h = 26,
h = 13, Back to the equation, use 13 as a sub. for all the h's
13+(13+4) = 30
13 + 17 = 30
Hope this helps!
Answer:
h + 4Step-by-step explanation:
The number of headbands Nikki has is represented by h, since it is an unknown value. To create a solvable equation, we can only have one variable. Since we know that Kristen has 4 more than Nikki has (4 more than h), we can represent this as h + 4, and solve for h. By doing this, we can then add to h to number 4 and determine how mnay headbands Kristen has.

I need help, -3x+9+4x=10 just wondering if the answer is X=1
Answer:
it's correct good job :)
Answer:
Step-by-step explanation:
Answer: Fortunately, you don’t have to prove that x or y must be 1 or -1 in order for x*y to not be an element of G.
You only need to prove that x*y is an element of G for any x,y in G. (That’s what it means for * to be an operation on G.)
I haven’t thought yet about how to prove that, but let me give you some thoughts off the top of my head.
We know -1 < x, y < 1. We must show -1 < (x + y) / (xy + 1) and (x + y) / (xy + 1) < 1.
First, let’s show that -1 < (x + y) / (xy + 1).
I want to multiply xy + 1 to both sides, but we need to know whether it’s positive or not, so we know whether to reverse the inequality.
Well, -1 < x, y < 1 implies that xy > -1, which implies that xy +1 > 0.
So we must show that -(xy + 1) < x + y.
That is, let’s show that 0 < x + y + xy + 1. (I don’t know if this is going anywhere useful; I’m just playing around with algebra.)
Solve the system by elimination.

Find the measures of ∠B and ∠C given that m∠B=(2.5x+6)∘ and m∠C=(7x−12)∘.
The figure shows triangle A B C. Side A B is congruent to side A C.
answers are one of the following
∠B = 4° and ∠C = 4°
∠B = 16° and ∠C = 16°
∠B = 20° and ∠C = 20°
Answer:
since AB=AC it is an isosceles triangle so ...
Step-by-step explanation:
angle B = angle C
2.5x + 6 = 7x - 12
4.5x = 18
therefore x = 4
substituting the value of x we get answer
angle B = 16
angle C = 16
The cost in dollars, y, to participate x days in a bike tour is a linear function. Lin's bike tour is described by the equation y = 5x + 50. The cost of Max's bike tour is $120 for a 14-day bike tour. If both Lin and Max take 14-day tours, whose bike tour costs less? Lin Max They cost the same amount
Answer:
They cost the same amount
Step-by-step explanation:
Given
Lin: [tex]y = 5x +50[/tex] where x = 14
Max: [tex]\$120[/tex] for 14 days
Required
Which is less expensive?
Max charges has been given from the question as; $120 for 14 days.
To determine Lin's, we simply substitute 14 for x in [tex]y = 5x +50[/tex]
[tex]y = 5 * 14 + 50[/tex]
[tex]y = 70 + 50[/tex]
[tex]y =120[/tex]
The above result of y shows that Max charges for 14 days is also $120.
Hence, they (Lin and Max) cost the same because they both equal to $120 for 14 days

Solve a/-6 + 8 = 12. a =
Answer:
a = -24
Step-by-step explanation:
[tex]\frac{a}{-6}+8 = 12 \\\\\frac{a}{-6} = 12 - 8 \\\\\frac{a}{-6}= 4\\\\a = 4*(-6)\\\\a = -24[/tex]
Answer:
-24
Step-by-step explanation:
a/-6 + 8 = 12
a/-6 = 12 - 8
a/-6 = 4
cross multiply,
a = -6 × 4
a = -24

Which equation describes the line that has a slope of –2 and passes through the point (1,3)?
Answer:
y = -2x + 5
Step-by-step explanation:
Slope-intercept form is writen like this; y = mx + b. Where m = slope and b = y-intercept.
We know the slope, so, find the y-intercept.
y = -2x + b
3 = -2(1) + b
3 = -2 + b
5 = b
Put everything we know/solved for into the original formula.
y = -2x + 5

find the value of 10z when z =0.8
Answer:
So, your answer to 10z would be 8.
Step-by-step explanation:
All you need to do is plug in 0.8 for z. A cool trick when multiplying by ten is you can move the decimal point over 1 to the right. So, 0.8 would become 08.0, aka 8.

If the two congruent angles (angles A and B) of an isosceles
triangle are each twice the third, non-equal angle. (angle C)
find the measure of the non equal angle, angle C.
Answer:
If the third angle is x, the other two angles are 2x
The measure of the angles of a triangle must add up to 180 degrees
x + 2(2x) = 180
x + 4x = 180
5x = 180
x = 36
The other two angles are 2x = 2 * 36 = 72
The three angles are 36, 72, and 72 degrees
Step-by-step explanation:
EXAMPLE-
x+2x+2x=180
5x=180
x=180/5
x=36º third angle
the equal angles are each 2*36=72º
The required measure of three angles are 36, 72, and 72 degrees in the given triangle.
What is an Isosceles Triangle?An Isosceles Triangle is defined as a triangle with two sides of equal length is an isosceles triangle.
Given that the third angle is x, the other two angles are 2x
We know that the measure of the angles of a triangle must add up to 180 degrees.
As per the given question, the equation would be as:
x + 2(2x) = 180
x + 4x = 180
5x = 180
x = 36
So, the other two angles are 2x = 2 × 36 = 72
Therefore, the required measure of three angles are 36, 72, and 72 degrees in the given triangle.

2. Now that you have the height of the cone, how can you solve for the
slant height, s?
Answer:
s^2 = r^2 + h^2.
Step-by-step explanation:
You need to know the radius of the base as well.
Then you use the Pythagoras theorem:
s^2 = r^2 + h^2 where r = radius and h = the height.
