Which of these inequalities is graphed below
Y>2x-6
Y<2x-6
Y<2x-6
Y>2x-6
Answer:
D
Step-by-step explanation:
The line looks dotted (image quality isn't the best) so we can already exclude the inequalities with [tex]\le[/tex] or [tex]\ge[/tex]. At this point let's check an "easy" point, 0.0.
[tex](0)>2(0)-6 \rightarrow 0>-6[/tex] Which is indeed true. The correct answer is D

What are the coordinates of the midpoint of AB if A (4, 6) and B(-8, 2)?
o (6, 4)
O (-6, 4)
O (-2, 4)
o (2, 4)
Answer:
(- 2, 4 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) , then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = A (4, 6 ) and (x₂, y₂ ) = B (- 8, 2 )
midpoint = ( [tex]\frac{4-8}{2}[/tex] , [tex]\frac{6+2}{2}[/tex] ) = ( [tex]\frac{-4}{2}[/tex] , [tex]\frac{8}{2}[/tex] ) = (- 2, 4 )
Midpoint be p(x,y)
P(x,y)=
[tex]\\ \sf\longmapsto \left(\dfrac{4-8}{2},\dfrac{6+2}{2}\right)[/tex]
[tex]\\ \sf\longmapsto \left(\dfrac{-4}{2},\dfrac{8}{2}\right)[/tex]
[tex]\\ \sf\longmapsto (-2,4)[/tex]

Determine if the leading coefficient of the following function is positive or negative and whether the function has a minimum or maximum vertex point.
Answer:
The leading coefficient of the function shown is negative and the function shown has a maximum vertex point.
Step-by-step explanation:
The leading coefficient is the term with the highest degree in a polynomial.
For example in 4x² + 3x + 1 the leading coefficient would be 4x² as 4x² is the term with the highest degree.
The leading coefficient tells us whether the equation, when graphed, will rise or fall.
If the leading coefficient is negative then the equation will fall when graphed, in contrast if the leading coefficient is positive the equation will rise when graphed.
Looking at the graph, it appears that the equation is falling, meaning that the leading coefficient must be negative.
If the equation falls then it has a maximum point, if it rises then it has a minimum point.
Because the equation shown falls it will have a maximum point.
(Please Help) (50 Points) Write the equation for the transformations of the graph of y = x^2
Use the form: y = a (x-h)^2 +k
Translated 2 units left and 7 units down.
A is the scale or vertical stretch
H is what makes it move right or left.
K is what makes it move up or down.
a = 1
h = -2
k = -7
y = (1) (x-(-2))² + (-7)
y= (x + 2)² -7
(Also, you will learn b in the equation. The equation would be a(b(x-h))² + k. B would be about horizontal compression.)

If you had half a dollar, three quarters, eight dimes, six nickels, and nine pennies, how much money would you have altogether?
Answer:
$1.69
Step-by-step explanation:
Half a dollar = $0.50
Eight dimes = $0.80
Six nickels = $0.30
Nine pennies = $0.09
Total = $0.50 + $0.80 + $0.30 + $0.09 = $1.69

Plzzzzzx help meeeeee
Step-by-step explanation:
first find out the area of sector ECF
π(10)² × 40°/360°
=100π×1/9
=100π/9 m²
now find the area of sector DCG
π(2)² × 40°/360°
=4π/9 m²*
so the area of the shaded region would be the big sector minus the small sector
so
100π/9 - 4π/9
=96π/9
=33.5 m² (3sig.fig.)
*Note that 4π/9 DOES NOT equal to 2π/3
4/9 DOES NOT EQUAL TO 2/3

Answer:
Slope of the parrelel line: -2/3x
Slope of the perpendicular line: 3/2x
Step-by-step explanation:
Lets first put this into slope intercept form:
y = mx + b
9y = -6x - 1
y = -2/3x = 1/9
So our slope is -2/3x
If we have a line parrelel to this, it means it has the exact same slope, but a different b value.
So the slope of this parellel line would also be -2/3x
Next we need to find the slope of the perpendicular line.
This is the exact opposite of our slope.
To find this, lets first understand our slope.
Our slope is the change in y over the change in x:
Δy/Δx
A perpendicular line is going to be the flipped, and negative of this.
You can think of a perpendicular line being:
-Δx/Δy
Since our slope is -2/3x
Our perpendicular line would be 3/2x
So our answer for the second question is 3/2x
Useful things to remember:
Slope of a line: Δy/ΔxSlope of a parrelel line: Δy/ΔxSlope of a perpendicular line: -Δx/ΔyHope this helps!
-2z+3-z=□-4z+2
please give me the answer
Step-by-step explanation:
[tex]\displaystyle \rm -2z+3-z=-4z+2 \\\\ -3z+3=-4z+2 \\\\ 4z-3z=-3+2 \\\\ \underline{z=-1 \ \ \ \ } \\\\[/tex]
[tex]\large{\rm{\underline{\underline{Answer:}}}}[/tex]
Given to solve: -2z+3-z = -4z+2
⇛ -3z + 3 = -4z + 2
⇛ -3z + 4z = 2 - 3
⇛ z = -1
Required value of z is -1. The steps we followed are: We shifted z to a single side and other numbers to other side. Then we equated to get the result.

Answer : -12.8
The table below represents a linear function. Identify the rate of change of the function.
(0,4) (4,-3) (8,-10) (12,-17)
Step-by-step explanation:
the rate of change is the slope of the line y/x. it is always the factor of x in the equation.
it indicates how many units y changes, when x changes a certain amount of units when going from one point to another.
we only need to look at 2 points.
to go from (0, 4) to (4, -3)
x changes by +4 (from 0 to 4),
y changes by -7 (from 4 to -3).
so the rate of change is -7/3

Answer:
x = 7
Step-by-step explanation:
The sum of exterior angles in a polygon is 360°.
( 11x - 5 )° + ( 4x + 29 )° + ( 6x + 13 )° + ( 9x - 15 )° + 67° + 61° = 360°
30x + 22 + 128 = 360
30x = 210
x = 7

FIND X
I will mark braniliest
Answer:
x = 11
Step-by-step explanation:
∠ EAB = ∠ AED = 4x ( alternate angles )
∠ AEB and ∠ GEB are adjacent angles on a straight line and sum to 180° , so
∠ AEB + 125° = 180° ( subtract 125° from both sides )
∠ AEB = 55°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ EBC is an exterior angle of the triangle , then
∠ EBC = ∠ AEB + ∠EAB , that is
9x = 55 + 4x ( subtract 4x from both sides )
5x = 55 ( divide both sides by 5 )
x = 11
