Key to a lock= 1264
Step-by-step explanation:
Sorry for the wait I just saw this question. Lol, I guess answer 1 is always equal to answer two but here is my work:
6(3)+21(4)=18+84=102
2(2(3)+7(4)=2(6+28)=12+56=102
5(6)x7(6)=30+42+72
6(5+7)=6(12)=72
14(10)+2=140+2=142
2(7(10)+1)=2(70+1)=2(71)=142
102+102+72+72+142+142=632
632 squared means 632x2 which is 1264.

Solve the system of equations by substitution.
-8x+2y=4
y=4x+2
Answers
Answer:
the answer by substitution would be y = 4x+2
Correct answer: Infinite solution because 2 = 2.
Set the first equation equal to y.
-8x + 2y = 4
+8x +8x
___________
2y = 8x + 4
__ ___ __
2 2 2
y = 4x + 2
At this step, you can choose any equation to substitute into the other equation. However, I'm going to substitute the new first equation with the second equation where y is. Solve for x.
y = 4x + 2
4x + 2 = 4x + 2
-4x -4x
____________
2 = 2
So, at this point, we know the system of equation does not have one solution. Thus, when the same number equals the same number, it is an infinite solution.
We can prove this by an online graphing tool. Insert the two equations onto the online graphing tool. If the lines appear to be on the same line, they have infinite solutions. Hope this helps :) Let me know if you have any questions related to this problem!
Help again 8th grade math really need help

A triangles angles will always add up to 180°.
Therefore, we can add these equations to get 180° and then find x.
(4x-2) + (7x-2) + (5x-8) = 180°
Now we simply the equation by combining like terms.
16x -12 = 180°
Now we can solve for x. ^w^
16x -12 = 180°
+12 +12
~~~~~~~~~~~~~
16x = 192
/16 /16
~~~~~~~~~~~~~
x = 12
Yay! We found x. Now we plug it into each equation:
~ 4x-2
4(12)-2
48-2
46°
~ 7x-2
7(12)-2
84-2
82°
~ 5x-8
5(12)-8
60-8
52°
It’s always a good idea to check if these angles add up properly to 180°.
46° + 82° + 52° = 180°
Congrats! We are all done ^u^

Which equation is the BEST fit for the data in the graph
Answers
Answer:
y = -8x + 75 (C)
Step-by-step explanation:
To find this, you first should take a look at the y-intercept (The point at which x=0) to narrow it down a bit. In this case, the y-intercept is 75. The standard form of a linear equation is y = mx + b, where b is the y-intercept. Since there is only 1 answer where b is equal to 75, C is the right answer.
A tetrahedron is a pyramid with a triangular base. Find the volume of the tetrahedron.
L = 3 in W = 4 in H = 11 in
Answers
Answer:
Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take as an example to see how the atoms actually bond in tetrahedron. It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.
