Answer:
A = 72
B = 16
Step-by-step explanation:
Ratio problems can often be worked by considering them in terms of "ratio units." Here, the difference in ratio units is 9-2 = 7. The difference between the actual numbers is A -B = 56. This means each ratio unit stands for an actual number value of 56/7 = 8
Then the ratio of actual values is ...
A : B = (9·8) : (2·8) = 72 : 16
Check: These actual values of A and B have a difference of 72-16 = 56.
(A, B) = (72, 16)
Write the sentence as an inequality.
A number y is less than 16.
The inequality is ____
66 points easy question if there are 20 red balls in the gym basket and need to put them in a group of 5. How many balls I will have in each group.
4 balls in each group.
Step-by-step explanation:
you just divide 20 by 5, or add 5 times until you get 20.
Answer:
5 group of 4 balls
Step-by-step explanation:
Red balls : 20
5 Gym baskets
20 - 5 15
15 divided by 5 3
3 divided by 20 0.15
0.15 divided by 5 0.03
0.03 x 15 0.45

g(x) = x-2, find g(-3)
Answer:
-5
Step-by-step explanation:
Since you are given [tex]g(x)[/tex] and what x is equal to (in this case, -3), all you have to do is plug the x back into the original equation.
[tex]g(x) = -3 - 2 = -5[/tex]

What is the solution to the system of equations?
3x - 2y = 8
6x - 4y = 12
Use any algebraic method (substitution or elimination) to justify that the given system of equations has no solution.
What do you know about the two lines in this system of equations graphically?
Answer:
Answer:
[tex]\displaystyle Inconsistency\:[No\:Solution][/tex]
Step-by-step explanation:
We need to isolate one pair of variables so they are set to zero. Now, in this case, we need to split one of the equations in negative half, so we will select the second equation:
[tex]\displaystyle \left \{ {{3x - 2y = 8} \atop {6x - 4y = 12}} \right. \\ \\ \\ \left \{ {{3x - 2y = 8} \atop {-\frac{1}{2}[6x - 4y = 12]}} \right. \\ \\ \left \{ {{3x - 2y = 8} \atop {-3x + 2y = -6}} \right. \\ \\ \\ \boxed{0 \ne 2}[/tex]
The fact that we have a result like this proves that we cannot obtain a solution from this system, which means that on a graph, these equations are considered parallel [no intersection, so no solution].

Mrs. Rodger got a weekly raise of ₫145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of ₫ 145.
So after completing the 1st week she will get ₫ (x+145).
Similarly after completing the 2nd week she will get ₫ (x + 145) + ₫ 145.
=[tex] ₫ (x + 145 + 145)[/tex]

An equation is shown below -5(2x-3)+2x = -10x+15
Find all the solutions if there are any for this equation
Answer:
-5(2x-3)+2x = -10x+15
-10x+15+2x= -10x+15
-12x+15 = -10x+15
-12x-(-10x):= -15+15

Restrict the domain of f(x)=x^2 to produce an inverse function?
Step-by-step explanation:
The range of the original is the domain of an inverse function, and the domain of an inverse function is the range of an original. Since the original equation/function f(x) = x^2 is a parabola with vertex at (0, 0) and opening downward.
I HOPE IT HELPS YOU
PLEASE MARK ME BRAINLIEST:)Write f(x) = 2x2 – 44x 185 in vertex form. to write f(x) = 2x2 – 44x 185, factor out from the first two terms. next, form a perfect square trinomial keeping the value of the function equivalent: f(x) = 2(x2 – 22x 121) 185 – 242 the function written in vertex form is f(x) = (x – )2 .
The quadratic function given when converted to vertex form will be: [tex]f(x) = 2(x-11)^2 -57[/tex]
What is vertex form of a quadratic equation?If a quadratic equation is written in the form
[tex]y=a(x-h)^2 + k[/tex]
then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)
We first take out coefficient of x squared, and then inside the bracket, we try to make perfect square like situation.
For this case, the given quadratic function is:
[tex]f(x) =2x^2 -44x + 185\\[/tex]
Converting this to the vertex form, we get:
[tex]f(x) =2x^2 -44x + 185\\\\f(x) = 2(x^2 -22x) + 185\\f(x) = 2(x^2 -2 \times 11 \times x + 11^2 - 11^2) + 185\\f(x) = 2((x-11)^2 -121) + 185\\f(x) = 2(x-11)^2 -242 + 185\\f(x) = 2(x-11)^2 -57[/tex]
Thus, the quadratic function given when converted to vertex form will be: [tex]f(x) = 2(x-11)^2 -57[/tex]

if 3x + 28 = 46 what is the value of 2x + 6
Answer:
18
Step-by-step explanation:
3x + 28 = 46
Subtract 28 from each side
3x + 28 = 46
3x+28-28 = 46-28
3x=18
Divide each side by 3
3x/3 = 18/3
x = 6
Find 2x+6

KEEPs 46 - 28 because it help solve for the x-value.
NEW EQUATION: 3x = 46 - 28
SIMPLIFY IT!
3x = 18
DIVIDE 3 to BOTH SIDES

KEEP: 18/3 because it give you the x-value.
NEW EQUATION: x = 18/3
SIMPLIFY IT!
x = 6
Now that we have your x-value we can substitute it into the equation of: 2x + 6
