Answer:
x>12-(2y)/(3)
y>18-(3x)/(2)
Step-by-step explanation:
Answer:
The solution is:
x = 5
y = 11
Step-by-step explanation:
15x+10y>180
Since I know 15 + 10 = 25, I subtracted 25 from 180.
180 - 25 = 155
Therefore, we know that x and y multiplied by 15 and 10 must equal anything more than 180. Therefore, there are a variety of solutions. However, this is the one that I chose.
15(5)+10(11)>180
75+110>180
185>180 <----- This is a true statement.

A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs 20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f(x) = 20x + 4.
Answer:
Range[4,24,44,64,84,104,124]
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW;
A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs
20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in
pounds can be represented by f x( ) = 20x + 4.
What is the range of the function for this situation?
The range of a function can be defined as the difference between the maximum and minimum function. From the question, we can deduced that the minimum function of X is 0 and no plate is added, and the maximum is 6
The given function is
f(x) = 20x + 4 =
f(0) = 20(0) + 4
= 4
f(6) = 20(6) + 4
= 124
Which means the range is within 4 and 124.
But we are told from the question that Each pair of plates weighs 20 lb, which means there is difference of 20ib each between 4 and 24
Then we can compute the range as [4,124] or (4,24,44,64,84,104,124)

In order to determine the slant height of several pyramids, Marjorie used the surface area formula, s= 1/2 pl+b for the slant height,l . Which equation , in terms of l, represents the correct transformation of the surface area formula?
Answer:
[tex]l=\dfrac{2(S-b)}{P}[/tex]
Step-by-step explanation:
The surface area formula for pyramids is given by :
[tex]S=\dfrac{1}{2}Pl+b[/tex] ...(1)
We need to arrange the formula for l.
Take b to LHS,
[tex]S-b=\dfrac{1}{2}Pl\\\\2(S-b)=Pl\ [\text{cross-multiplying}]\\\\l=\dfrac{2(S-b)}{P}[/tex]
So, the expression is [tex]\dfrac{2(S-b)}{P}[/tex] for the slant height.

NEED HELP ASAP!!!!! PLEASE HELP ME
Answer:
m∠A = 40°
m∠B = 70°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
x + 49 + x + 79 + 70 = 180
2x + 198 = 180
2x = 180 - 198
= -18
x = -18 ÷ 2
x = -9
m∠A = x + 49
= (-9) + 49
m∠A = 40°
m∠B = x + 79
= (-9) + 79
m∠B = 70°

On July 3, the ABC corporation closed at $43.67. This was a $0.47 increase from the close the day before. What percentage change is this?
Answer:
+1.09%
Step-by-step explanation:
Complete the square:
x^2 +6x +c
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
So c= -9
The completed square form of the original expression is (x+3)² - 9 and the value of c is -9.
How to compute the perfect square?To compute the square, you need to add and subtract a number inside the parentheses such that the resulting expression is a perfect square trinomial.
To determine the square of half of the coefficient of the x term, which is 3 in this case.
The square of 3 is 9, so you need to add and subtract 9 inside the parentheses to complete the square. The resulting expression will be:
(x+3)² + c
To find the value of c, you need to compare this expression to the original expression: x² + 6x + c.
The x² and (x+3)² terms are equal, so you can set them equal to each other and solve for c:
x² = (x+3)² + c
x² - (x+3)² =c
(x-x-3)(x+x+3) = c
(-3)(3) = c
-9 = c
Therefore, c = -9.

Step-by-step explanation:
Step 1: Define Equation
8x - 3 = 2(x - 1/2)
Step 2: Solve for x
Distributive 2: 8x - 3 = 2x - 1Subtract 2x on both sides: 6x - 3 = -1Add 3 to both sides: 6x = 2Divide 6 on both sides: x = 1/3
