Which shows the result of a correct substitution for the system y=2x+3 and 3x+2y=9?
o
A. y= 2y + 3
B. 3(2x + 3) + 2y = 9
C. 3x + 2(2x + 3) = 9
o
D. 2x + 2y = 3
Answer:
C. 3x + 2(2x + 3) = 9
Step-by-step explanation:
We are given the following relation:
y = 2x + 3
And we want to substitute into:
3x + 2y = 9.
So
[tex]3x + 2(2x + 3) = 9[/tex]
Which is given by option C.

y = 3x - 7
Is it linear or exponential
Answer:
Linear
Step-by-step explanation:
The equation y = 3x - 7 is a linear.
A linear equation represents a straight line on a graph, where the variables (in this case, x and y) have a linear relationship.
The equation has a constant coefficient (3) multiplying the variable (x), and a constant term (-7) added or subtracted.
An exponential equation involves variables in the exponent, such as
y = abˣ, where a and b are constants.
The variable x is in the exponent, indicating exponential growth or decay.
Since the equation y = 3x - 7 has a linear relationship and represents a straight line, it is classified as a linear equation.

Joy’s job pays $12.25 an hour. One day, she worked for 320 minutes. How much will she earn?
Answer:
about $64.8
Step-by-step explanation:
First of all, we know that there is 60 min per hour.
So we find out how many hours 320 minutes is equivelant to.
We can solve this by doing 320/60 = 5\frac{1}{3}
To find how much Joy makes, simply do $12.25 x $5\frac{1}{3} = 28

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Alex paints a total of 9 dollhouses using 2 cans of paint.
So, to obtain the no. of doll houses Alex can paint with each can of paint we'll divide the total no. of dollhouses painted by the total no. of paint cans used which is,
= (9/2) dollhouses.
= 4.5 doll houses.

Which statement is an example of the transitive property of congruence?
Answer:
Step-by-step explanation:
The transitive property in general says. The transitive property of congruence states that two objects that are congruent to a third object are also congruent to each other.
if a=b and b=c, then a=c
The transitive property of congruence replaces the equal sign with a congruence symbol, and replaces a, b, c with any geometric figure. Here the geometric figures used are triangles KLM, PQR, and STU.
If ΔKLM ≅ ΔPQR and ΔPQR ≅ ΔSTU, then ΔKLM ≅ ΔSTU hope this helps
Answer:
Step-by-step explanation:
If KML=PQR and PQR = STU then KML=STU because of the transitive property of congruence.

A new health drink has 170% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 30mg. How many milligrams of the vitamin are in the drink?
Answer:
51 mg
Step-by-step explanation:
A new health drink has 170% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 30mg.
The above question is calculated as:
RDA of the vitamin × 170%
The RDA for this vitamin is 30mg
Hence:
30mg × 170%
= 51 mg
Therefore, the milligrams of the vitamin that are in the drink is 51 mg
Addison prepared 30 kilograms of dough after working 3 hours. How many hours did Addison work if she prepared 50 kilograms of dough? Assume the relationship is directly proportional.
Answer:
Addison worked 5 hours
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
The relationship between the number of kilograms of dough Addison prepares (y) is proportional to the number of hours he works on it (x).
Knowing he prepared y=30 kilograms of dough after t=3 hours, we substitute in the function:
30 = 3k
Solving for k:
k = 30/3 = 10
The relationship is:
y = 10x
If he prepared y=50 kg of dough, then:
50 = 10x
Solving for x
x = 50/10 = 5
Addison worked 5 hours

during a lunch seminar, chocolate, caramel and strawberry topping were available how many 2 topping sundaes are possible?
Answer:
There are 3 two topping sundaes possible.
Step-by-step explanation:
The order in which the toppings are chosen is not important. For example, chocolate and caramel topping is the same as a caramel and chocolate topping. So we use the combinations formula to solve this question.
Combinations Formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
How many 2 topping sundaes are possible?
2 toppings from a set of 3(chocolate, caramel and strawberry). So
[tex]C_{3,2} = \frac{3!}{2!(3-2)!} = 3[/tex]
There are 3 two topping sundaes possible.
