i need answer please 6x + 3y + 2x + y
Answer:
8x +4y
Step-by-step explanation:
6x + 3y + 2x + y
1) add similar variables together.
2) 6x + 2x = 8x
3y + (1)y = 4y.
3) y by itself basically means 1y, since in front of every variable theres an invisible 1.
6x + 3y + 2x + y
Simplified: 4 · ( 2x + y)
Answer= 11y
Is the following relation a function? {(1, 2), (4, -3), (4, 7), (8, -6)}
a. Yes
b. No
help plsss
Answer:
A function will not have any repeating x values...it can have repeating y values, just not the x ones. So all ur x's have to be different.
This relation is NOT a function because u have repeating x values...u have 2 x values that are 0.3

Find the value of w,then x. Round to the nearest tenth
Answer:
A
Step-by-step explanation:
12 / tan 42 = 13.32......
12 / sin 27 = 26.43....
26.43² - 12² = 552.24....
square root of 552.24... = 23.5
23.5 - 13.3 = 10.2

Find the vertex of the quadratic equation f(x) = x2 - 4x - 10
Answer:
2
Step-by-step explanation:
Answer:
vertex = (2, - 14 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² - 4x - 10
Using the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² - 4x
f(x) = x² + 2(- 2)x + 4 - 4 - 10
= (x - 2)² - 14 ← in vertex form
with vertex (h, k ) = (2, - 14 )

Find the total surface area of the net below.
Answer:
122
Step-by-step explanation:
The total surface area is 122. This is because 7 times 4 equals 28. Then you do 7 times 5 twice, which makes 35 times 2, which makes 70. This is because there are 2 triangles with 7 as the base and 5 as the height. Next, you do 4 times 3 twice, which equals 12 + 12 which adds up to 24. Now add the numbers up. 70 + 28 + 24, which = 122.

Solve for x.
Help please(:
Answer:
x = 10°
Step-by-step explanation:
As we can see it is an equilateral triangle so all sides and angles are equal.
6x + 6x + 6x = 180° { being sum of angles of triangle }
18x = 180°
x = 180° / 18
x = 10°
Hope it will help ✔
Hey there
Answer:
10°
Step-by-step explanation:
Since all sides are equal.
Then,
It is the equilateral triangle
Therefore,
All sides are equal to 60°
Now,
60° = 6x
60°/6 = x
10° = x

Answer:
A. 2, 84, 40
Step-by-step explanation:
x/3 = 8/12
x = 3*8/12 =24/12 = 2
56/y = 8/12
y = 56*12/8 = 7*12 = 84
8/12 = z/ 60
z = 8*60/12 = 40
Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.
Answer:
[tex]\frac{13}{\sqrt{2}}[/tex] or 9.19 (approximately). I am confused how the question is asking for it to be typed, so it might be this: [tex]\frac{13}{\sqrt{2}}[/tex] , but if you cannot type that in, then maybe it is sin(45) * 13.
Step-by-step explanation:
The three main trigonometric ratios are: sine (o/a), cosine (a/h), or tangent (o/a) depending on the given. To help you remember them, you can use the saying SOH CAH TOA, which is sin = opposite/hypotenuse, cosine = adjacent/hypotenuse, and tangent = opposite/adjacent.
In this problem, we are going to use one that has the hypotenuse, which rules out tangent, and leaves us with sine or cosine. Since, we are given the hypotenuse and the opposite side (from angle 45), we will be using sine. Then we just need to set up the trigonometric ratio:
sin (45) = x/13
Then, you need to get x by itself, so you multiply 13 on each side, which leaves you with:
x = sin(45) * 13 = 9.19 (approximately)
This could also be seen as a special right triangle, where the hypotenuse is [tex]x\sqrt{2}[/tex], and the two sides are x.
So, to find the value of x, you could also do this: 13/[tex]\sqrt{2}[/tex], which might be how the question wants it formatted.
Good luck!

Answer: 45 = 5t
Step-by-step explanation:
From the question, Jamahl wants to celebrate his birthday by roller skating with his friends and he has a total of $45dollar to buy t tickets.
We are further told that the ticket costs $5. The equation that matches the situation will be:
45 = (5 × t)

Jane is making wind seashells. She need 12 sea shells for the big one and 8 for the small one. How many wind chimes of the same number would she make form 100 sea shells?
Answer: See explanation
Step-by-step explanation:
Let the wind chimes of the same number that would make her form 100 sea shells be represented by x.
From the information given in the question, this can be denoted as:
12x + 8x = 100
20x = 100
x = 100/20
x = 5
She'll need 5 wind chimes. Let's check
12x + 8x
12(5) + 8(5)
60 + 40 = 100
