Answer:
x = - 2, y = - 2
Step-by-step explanation:
Given the 2 equations
y = 2x + 2 → (1)
4x - y = - 6 → (2)
Substitute y = 2x + 2 into (2)
4x - (2x + 2) = - 6 ← distribute and simplify left side
4x - 2x - 2 = - 6
2x - 2 = - 6 ( add 2 to both sides )
2x = - 4 ( divide both sides by 2 )
x = - 2
Substitute x = - 2 into (1) and evaluate for y
y = 2(- 2) + 2 = - 4 + 2 = - 2
solution is x = - 2, y = - 2

PLZZZZ HELP MEEEEE X(
Answer:
120°
Step-by-step explanation:
From the above question, the polygon is and hexagon, this means it has 6 sides.
Hence: Sums of the interior angles of a polygon = Sum = (n-2) × 180°
n = 6
Hence,
Sum of the interior angles = (6 - 2) × 180°
= 4 × 180°
= 720°
Hence:
The measure of an interior angle of a hexagon =
= Sum of the interior angles/Number of sides of the polygon
= 720°/6
= 120°
Answer:
120

please help me out! determine the domain on this graph
Answer:
Domain: 6 </= x < 11
Step-by-step explanation:
Domain refers to the set of possible input values, therefore the domain of a graph consists of all the input values shown on the x-axis.
Remember (this is very important!) :
Closed circles means including that number whereas open circles means not including that number
Domain: 6 </= x < 11
Note: </= means "less than or equal to"

Final answer: aby/2 = c
A line with a slope of 5 passes through the point (2, 5). What is its equation in
slope-intercept form?
Answer:
y = 5x - 5Step-by-step explanation:
slope-intercept form of equation: y = mx + b
where m is slope and b is y-intercept
If line y=ax+b passes through point (x₀,y₀) that means
that the equation y₀=ax₀+b is true
(2, 5) ⇒ x=2, y=5
m = 5
So:
5 = 5×2 + b
5 = 10 + b
b = -5
Therefore equation in slope-intercept form:
y = 5x + (-5)
y = 5x - 5
The equation of the line in slope-intercept form is y = 5x - 5.
Given that the slope of the line is 5 and it passes through the point (2, 5), we can use the point-slope form of a linear equation to find the equation of the line.
The point-slope form is given by:
y - y1 = m(x - x1),
where (x1, y1) is the given point and m is the slope.
Substituting the values, we have:
y - 5 = 5(x - 2).
Now, let's simplify this equation:
y - 5 = 5x - 10.
Next, let's isolate y:
y = 5x - 10 + 5.
Simplifying further:
y = 5x - 5.
So, the equation of the line in slope-intercept form is y = 5x - 5.

Answer:
$60
Step-by-step explanation:
So from the question, we need to find the fixed amount for the tv's. So we have to make an equation, and don't forget to add the extended warranties:
11(x + 25) = 935
x will represent a tv, and the 25 is the extended warranty for a tv, since the questions states 11 tv's with warranties is 935, the equation will look like that. Now lets slove:
11(x + 25) = 935
multiply
11x + 275 = 935
subtract 275 from both sides
11x = 660
divide both sides by 11
x = 60, each tv is $60
