What is the solution to the system of equation? Write you answer as a coordinate point.
Answers
Answer:
Step-by-step explanation:
Ok, so we have the equations:
7x-2y=-13
and
2y-5x=11
So first things first, we can cancel out 2y from both equations because they are common factors.
So we are left with the equations:
7x=-13
and
5x=11
So we add the two common factors and get:
12x=-24
And now we divide on both sides and get:
x=-2

[tex]33^2 + 56^2 = c^2\\1089 + 3136 = c^2\\4225 = c^2\\c = \sqrt{4225} \\c= 65[/tex]
Answer:
Third side is 65
Step-by-step explanation:
FORMULA
a^2 + b^2 = c^2
PLUG IT IN
33^2 + 56^2 = c^2
33 and 56 are the legs of the triangle so they go into the A and B variable.
The legs make up the right angle.
C is the hypotenuse, and here it is the diagonal line in that image.
FIND THE NUMBERS SQUARED
1089 + 3136 = c^2
ADD THEM TOGETHER
4225 = c^2
SQUARE ROOT BOTH SIDES
[tex]\sqrt{4225}[/tex] = ([tex]\sqrt{C}[/tex])^2
65 = c
CHECK
33^2 + 56^2=65^2
1089 + 3136 = 4225
4225 = 4225

Can someone help i suck at math
Answers
Answer:
Table 3
Step-by-step explanation:
In a proportional relationship there must be a constant rate of change.
The first table:
6-5 / 9-7 = 1/2
5-3 / 7-4 = 2/3
These are not equal so it is not proportional.
The second table:
10-8 / 150-120 =2/30
8-5 / 120-75 = 3/45
These are not equal so it is not proportional
The third table:
10-8 / 12-10 =2/2 = 1
8-6 / 10-8 =2/2 = 1
These are equal so this table is proportional.

Create two imaginary numbers that multiply to get - 60 . (There are multiple solutions)
Answers
Answer:
10 x -6 = -60
Step-by-step explanation:
The number that multiplies to get -60 are (-2, 30), (-3, 20), (-4, 15), (-5, 12), (-6, 10), (2, -30), etc.
What is multiplication?
The fundamental concept of making the same number of additions repeatedly is represented by the action of multiplication. The results of multiplying two or more integers are known as the products, and the factors that are used in the multiplication are referred to as the factors.
Given:
The number is -60,
Factorize the number as shown below,
60 = 2 × 2 × 3 × 5
Here, the two numbers can be many, some of them are mentioned below,
-60 = 2 × (-30)
-60 = 3 × (-20)
-60 = 4 × (-15)
-60 = 5 × (-12)
-60 = 6 × (-10)
The number can be changed by changing the sign as shown below,
-60 = -2 × 30
-60 = -3 × 20
-60 = -4 × 15
-60 = -5 × 12
-60 = -6 × 10
Thus, the numbers are (-2, 30), (-3, 20), (-4, 15), (-5, 12), (-6, 10), (2, -30), etc.

(-4,9),(6,4) in point slope form
Answers
Answer: [tex]y-4=-\frac{1}{2} (x-6)[/tex]
Step-by-step explanation:
The point-slope form is y-y₁=m(x-x₁). y₁ and x₁ are from a point, and m is slope.
To find slope, we use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{4-9}{6-(-4)}=\frac{-5}{10}=-\frac{1}{2}[/tex]
Now that we have the slope, we can fill in our point-slope form equation.

Given the matrices
[tex]A=\begin{pmatrix}1&-1\\ 2&1\end{pmatrix}[/tex]
[tex]B=\begin{pmatrix}1&2\\ \:3&4\end{pmatrix}[/tex]
Calculating AB:
