Answer and Step-by-step explanation:
To solve an inequality, you must solve for the variable. Let's look at an example:
4x + 2 > 10
We solve for x by subtracting 2 from both sides, then dividing 4 on both sides.
(Solve as if you were solving a regular equation)
4x > 8
x > 2
We get x > 2 as our inequality.
To plug in 3 values, simply plug in any number that is greater than 2. That would be the solution to the inequality.
If when solving the inequality and you have to divide by a negative, the sign will change. Ex:
-5x > 25
x < -5
To show that the sign should switch, let's solve it this way.
-5x > 25
0 > 25 + 5x Add the 5x to both sides.
-25 > 5x Subtract the 25 from both sides
-5 > x Divide by 5 from both sides.
As we can see, the inequalities turn out to be the same, which is why you flip the sign when you divide.

Marion bought 14 packages of plastic frog and lizard fishing lures. She bought frog lures in
packages of 4 and lizard lures in packages of 6 for a total of 72 lures. How many of each lure did
Marion buy?
A. 6 lizards and 4 frogs
B. 4 lizards and 8 frogs
C. 48 lizards and 24 frogs
D. 24 lizards and 48 frogs
Answer:
C. 48 lizards and 24 frogs
Step-by-step explanation:
Let F = number of frog lures, and let L = number of lizard lures.
Marion bought 14 packages of plastic frog and lizard fishing lures.
She bought frog lures in packages of 4 and lizard lures in packages of 6 for a total of 72 lures.
F + L = 72
F/4 + L/6 = 14
12 * F/4 + 12 * L/6 = 12 * 14
3F + 2L = 168
(+) -3F - 3L = -216
------------------------------
-L = -48
L = 48
F + L = 72
F + 48 = 72
F = 24
Answer: C. 48 lizards and 24 frogs

Find the slope using points ( 7,-3) and (11,-4)
Answer:
1/4
Step-by-step explanation:
Answer:
m = [tex]-\frac{1}{4}[/tex]
Step-by-step explanation:
Use the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) = (11 , -4)\\(x_2 , y_2) = (7 , -3)\\[/tex]
Plug in the corresponding numbers into the corresponding variables:
slope (m) = [tex]\frac{-3 - (-4)}{7 - 11} = \frac{-3 + 4}{7 - 11} = \frac{1}{-4} = -\frac{1}{4}[/tex]
[tex]-\frac{1}{4}[/tex] is your answer.

A patio 2 pairs of two parallel sides and 2 pairs of sides that are the same length there are 4 square corners what shape is the patio
Answer:
The patio is a rectangle
Step-by-step explanation:
Since it is given that we have 2 pairs of two parallel sides, which implies 4 sides, this thus shows that the shape is a quadrilateral since, only quadrilaterals have 4 sides. Also, 2 pairs of sides are the same length, and are parallel, it shows that the shape is likely a rectangle.
Finally, there are 4 square corners on the shape which implies 4 right angles. This confirms that our shape is a rectangle since only a rectangle has 2 pairs of two parallel sides and 2 pairs of sides that are the same length there are 4 square corners.
So, the patio is a rectangle.

To help you, Remeber the SOHCAHTOA rule
When It asked to find sin, cos, tangent of a angleIf you finding the sin of a angle you must find the side that is Opposite then put it over the hypotenuse I'll do 3,6,7,8 for you.
For 3,The side that is opposite of c is 28 and the hypotenuse (which is the longest side of the triangle) is 35. So the answer is 28/35. or 4/5.
For 6, 32 is opposite of A and 40 is the hypotenuse so
32/40 or 4/5 is our answer.
For 7, 24 is opposite of Z and 40 is the hypotenuse so
24/40 or 3/5 is the answer.
For 8, 14 is opposite of Angle C and 50 is our hypotenuse so
14/50=7/25 is our answer
COS
To find cos it is adjacent/hypotenuse
For 2 the adjacent side to C is 16 and the hypotenuse is 34. so our answer is 16/34 or 8/17.
For 5, the adjacent side is 30 and the hypotenuse is 34 so our answer is 30/34 or 15/17
For 9, the adjacent side is 24 and hypotenuse is 30 so our answer is 24/30 or 5/6.
TAN
TO FIND TAN, it is Opposite/Adjacent
4, the opposite side is 32 and the adjacent is 24 so our answer is 32/24 or 4/3.
10, the opposite side is 27 and the adjacent is 36 so our answer is 27/36 or 3/4

[tex] \frac{25}{12} [/tex]
Step-by-step explanation:
1) Use this rule: a ÷ b/c = a × c/b.
[tex] \frac{25}{4} \times \frac{1}{3} [/tex]
2) Use this rule: a/b × c/d = ac/bd.

Answer:
$11,988
Step-by-step explanation:
A graphing calculator gives you the answer easily.
The minimum unit cost is $11,988.
__
The equation for unit cost can be put into vertex form to find the minimum.
C(x) = 0.7x^2 -210x +27738
C(x) = 0.7(x^2 -300x +150^2) +27738 -0.7(150^2)
C(x) = 0.7(x -150)^2 -11,988
This is vertex form:
C(x) = a(x -h)^2 +k . . . . . . . where (h, k) is the vertex.
The vertex of this cost function is (150, 11,988).
The minimum unit cost occurs when 150 engines are produced. That unit cost is $11,988.
Answer:
the answer is $11,988

What is the product?

negative 81 t squared minus 16
negative 81 t squared + 16
negative 81 t squared minus 72 t + 16
negative 81 t squared + 72 t + 16
Answer:
The product is -81 t² + 16
Step-by-step explanation:
The product of two binomials (ax + b)(cx + d), where a, b, c, and d are constant
Multiply (ax) by (cx) ⇒ 1st × 1st
Multiply (ax) by (d) and (b) by (cx) ⇒ ext-reams and nears
Add the two products ⇒ like terms
Multiply (b) by (d) ⇒ 2nd × 2nd
Let us find the product of (9 t - 4) and (-9 t - 4)
Multiply the 1st two terms
∵ (9 t)(-9 t) = -81 t²
Multiply the ext-reams
∵ (9 t)(-4) = -36 t
Multiply the nears
∵ (-4)(-9 t) = 36 t
Add the like terms
∵ -36 t + 36 t = 0
Multiply the 2nd two terms
∵ (-4)(-4) = 16
Write the answer
∴ (9 t - 4)(-9 t - 4) = -81 t² + 0 + 16
∴ (9 t - 4)(-9 t - 4) = -81 t² + 16
The product is -81 t² + 16

Which method correctly solves the equation using the distributive property?
Negative 0.2 (x minus 4) = negative 1.7
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x minus 4 = negative 1.7.
Negative 0.2 x = 2.3. x = negative 11.5.
Negative 0.2 (x minus 4) = negative 1.7.
x minus 4 = 0.34. x = 4.34.
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x + 0.8 = negative 1.7.
Negative 0.2 x = negative 2.5. x = 12.5.
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x minus 0.8 = negative 1.7.
Negative 0.2 x = negative 0.9. x = 4.5.
Answer:
Negative 0.2 (x minus 4) = negative 1.7.
Negative 0.2 x + 0.8 = negative 1.7.
Negative 0.2 x = negative 2.5. x = 12.5.

I need this ASAP What is the image of the point (-7,-3) after a rotation of 180 counterclockwise about the origin?
The coordinates of the image after a rotation of 180° counterclockwise about the origin is A' ( 7 , 3 )
What is Rotation?The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (-y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)
Given data ,
Let the coordinate of the point be A
Now , the value of A is A ( -7 , -3 )
And , 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
So , the coordinates of the image is A'
And , the value of A' = A' ( 7 , 3 )
Hence , the rotation is solved and the image is A' ( 7 , 3 )

Which of the following equations corresponds to the graph below
Answer:
d) y = -1/2 + 3
Step-by-step explanation:
Looking at the graph, we can use y = mx + b to find the equation. m is the slope and for slope, we go 1 unit down and 2 units to the right. b is the y variable and our b would be 3.
y = mx + b
y = -1/2x + 3
