Answer:
(0, -4)
Step-by-step explanation:
Given the inequality expression
y>−2x+y≤4
This can be splitted into
y>−2x+y .... 1
and -2x+y≤4 .... 2
From1;
y>−2x+y
y - y >−2x
0 >−2x
-2x < 0
x > 0/-2
x>0
Substitute x = 0 into 2
-2(0)+ y ≤4
y≤4
Hence the solution is (0, -4)

| -7-1 | =
Please show work
Answer:
Solving |-7-1| we get 8
Step-by-step explanation:
We need to solve |-7-1|
Absolute value is non-negative number even the number has negative sign.
So, |a| = a or |-a|=a
So, solving |-7-1|
=|-8|
=8
So, Solving |-7-1| we get 8

What is the equation of a line that passes theough the points (-3,4) and (2,8)?
[tex]\begin{cases} (x_1,y_1)=(-3,4) \\ (x_2,y_2)=(2,8) \end{cases} \\ m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Substitute the coordinate values in.[tex]m = \frac{8 - 4}{2 - ( - 3)} \\ m = \frac{4}{2 + 3} \Longrightarrow \frac{4}{5} [/tex]
We have got the value of slope. Substitute in the slope-intercept form.
Slope-Intercept[tex]y = mx + b \\ \sf{m = slope}\\ \sf{b = y - intercept}[/tex]
Substitute and Rewrite the equation.
[tex]y = \frac{4}{5} x + b[/tex]
Find the y-intercept or the value of b by substituting any given coordinate points.I will substitute (2,8) in.
[tex]y = \frac{4}{5} x + b \Longrightarrow \sf \small{Substitute \: \: the \: \: coordinate \: \: points \: \: in \: \: the \: \: equation}[/tex]
[tex]8 = \frac{4}{5} (2) + b \\ 8 = \frac{8}{5} + b \\ 40 = 8 + 5b \\ 40 - 8 = 5b \\ 32 = 5b \\ \frac{32}{5} = b[/tex]
Rewrite the equation by substituting the value of b.
[tex]y = \frac{4}{5} x + \frac{32}{5} [/tex]
Answer[tex] \large \boxed{y = \frac{4}{5} x + \frac{32}{5} }[/tex]

a, b, c, or d
Answer:
c
Step-by-step explanation:
2x-3 > 2x-5/2
⇒2x-3/1=2x-5/2
⇒(2x-3)×2=(2x-5)×1
4x-6=2x-5

The sixth term is -3,072
Step-by-step explanation:
Here, we want to get the 6th term
From the question, the first term is -12
the common ratio would be -12/3 = -4
So the sixth term will be;
ar^5
= 3 * (-4)^5 = -3072

Solve the following inequality:
2(4– 1) < 2(3v + 1).
Answer:
v>2/3
Step-by-step explanation:
2(4−1)<2(3v+1)
Step 1: Simplify both sides of the inequality.
6<6v+2
Step 2: Flip the equation.
6v+2>6
Step 3: Subtract 2 from both sides.
6v+2−2>6−2
6v>4
Step 4: Divide both sides by 6.
6v/6>4/6
v>2/3
Answer:
v>2/3
Step-by-step explanation:
Switch sides: 2(3v+1)>2(4-1)
Ope the brackets and multiply
6v+2)>2*3
Subtract 2 on both sides
6v>6-2
6v>4
v>4/6
v>2/3

Answer:
Not a triangle
Step-by-step explanation:
In order for a shape to qualify as a triangle, the interior angles must add up to 180°
These angles only add up to 56°, therefore it is not a triangle.
Answer:
obtuse
Step-by-step explanation:
You have an isosceles triangle. 2 of the sides are equal in length. Since, the third side is longer than than the other 2, it will form an obtuse angle. If the third side was shorter, you would have all acute angles.

Step-by-step explanation:
The points (8, -10) and (-21, 4) form a line segment.
Write down the midpoint of the line segment.
Answer:
The coordinates of the midpoint are;
(-6.5, -3)
Step-by-step explanation:
Here, we want to get the midpoint of the line segment
To get this, we use the midpoint formula;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
Thus;
(x,y) = (8 - 21)/2, (-10 + 4)/2
(x,y) = -13/2 , -6/2
(x,y) = (-6.5 , -3)

The perimeter of a square is represented by the expression 32x - 12.8 find the side length of the square.
Given:
Perimeter of a square = [tex]32x-12.8[/tex]
To find:
The side length of the square.
Solution:
We know that, the perimeter of the square is 4 times of its side length.
[tex]P=4a[/tex]
Where, a is the side length.
Perimeter of a square = [tex]32x-12.8[/tex]
Now,
[tex]4a=32x-12.8[/tex]
Divide both sides by 4.
[tex]a=\dfrac{32x-12.8}{4}[/tex]
[tex]a=\dfrac{32x}{4}-\dfrac{12.8}{4}[/tex]
[tex]a=8x-3.2[/tex]
Therefore, the side length of the square is [tex]8x-3.2[/tex] units.
Lily is making mittens for her friends. Her profit equation is P=-2x squared+20x+0, where P is her profit for the day, and x is how much she charges per pair of mittens. How much should Lilly charge per pair of mittens to make her max profit?
Answer:
$5
Step-by-step explanation:
We are given that profit equation
[tex]P(x)=-2x^2+20x+0[/tex]
Where x=Charges per pair of mittens
We have to find the charge per pair of mittens to make her max profit.
Differentiate equation w.r.t x
[tex]\frac{dP}{dx}=-4x+20[/tex]
[tex]\frac{dP}{dx}=0[/tex]
[tex]-4x+20=0[/tex]
[tex]4x=20[/tex]
[tex]x=5[/tex]
Again differentiate w.r.t x
[tex]\frac{d^2P}{dx^2}=-4<0[/tex]
Hence, the profit is maximum at x=5
Lily should charge $5 per pair of mittens to make her max profit .
