David is solving a system of linear equations by graphing. First he graphed both equations on a coordinate plane . What should be his next step in solving the system of linear equations
Answer:
look for coordinates of their intersection
Step-by-step explanation:
When looking at a system of equations you want an answer that satisfies both equations. This is no different on a graph. On the graph, you want a point that satisfies both lines. This point would be their intersection.

Step-by-step explanation:
Which measure is of an angle that is coterminal with a 95° angle?
Answer:
95° - (1,080 n) °, for any integer n
Step-by-step explanation:
Co-terminal angle are those angles who share the same initial side and terminal sides,
And, these angles are obtained by adding or subtracting the multiple of 360°,
That is, if Ф is an angle,
Then its co-terminal angles are,
Ф + 360 n
Where, n is any integer (negative or positive)
Here, Ф = 95°,
Since, n is an integer,
⇒ - 3n is an integer,
Thus, the co-terminal angles of 95° are,
95° + 360° (-3n)
= 95° - (1080 n) °; for any integer n.
Step-by-step explanation:
Hope this helps!~
And I hope this is what you where looking for.
Good Luck!~

Choose the linear inequality that describes the graph. The gray area represents the shaded region.
4x – 6y ≥ 10
4x + 6y ≤ 10
4x + 6y ≥ –10
4x + 6y ≥ 10
please help !
Answer:
4x+6y<=10
Step-by-step explanation:
The linear inequality that describes the graph is 4x+ 6y ≤ 10.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
As, The bold straight line passes through the points (1,1) and (-2, 3).
so, equation of line will be
(y- 1) = (3-1)/ (-2-1) (x-1)
y-1 = 2 / (-3) (x-1)
-3y + 3 = 2x - 2
-3y -2x = -5
If we multiply by 2 both side we get
-6y - 4x = -10
4x+ 6y= 10
So, the required inequality for gray area is 4x+ 6y ≤ 10.

Answer:
-13,-7,-3,0,3
-9,-4,-6,3,8
Step-by-step explanation:
Answer:
A) -13, -7, -3, 0, 3 B) -100, -99, -8, -25/3, -2
Step-by-step explanation:
3)Ordered from least to greatest is: -13, -7, -3, 0, 3
(The higher the negative the "smaller" it is)
4) -100, -99, -8, -25/3, -2
These numbers are listed in order from least to greatest with the error being -25/3. This equals -8.333 and should be in front of the -8 because it is a lesser value. The correct order would be: -100, -99, -25/3, -8, -2 but your answer asks for one error so use the numbers above.

3x - 7y and - 7y + 3x are equivalent expressions
3x is positive and - 7y is negative
As long as the signs on their coefficients do not change then they can be reversed, that is
3x - 7y = - 7y + 3x
Which would be an equivalent way to write y= 2 - 3x ?

Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it
Answer:
Step-by-step explanation:
First use distributive property: a(b + c) = a*b + a*c
3n - 6 = -8(6 + 5n)
3n - 6 = 6 * (-8) + 5n *(-8)
3n - 6 = -48 - 40n
Now add 40n to both sides
3n - 6 + 40n = -48 - 40n + 40n
43n - 6 = -48
Now add 6 to both sides
43n - 6 + 6 = -48 + 6
43n = -42
n = -42 /43
Answer:
0.98
Step-by-step explanation:
3n-6=-8(6+5n)
3n-6=-48-40n
3n=-48-40n+6
40n+3n=-42
43n=-42
n=0.98 (I rounded it)

Three angles are in the ratio 2:3:5
The smallest angle is 50
Work out the sizes of the other two angles
Answer:
The other two angles are 75° and 125°.
Step-by-step explanation:
Let three angles are 2x, 3x and 5x.
The smallest angle is 50.
It means,
2x = 50
x = 25
So,
3x = 3(25) = 75°
5x = 5(25) = 125°
So, the other two angles are 75° and 125°.
