Answer:
x = 8
Step-by-step explanation:
2x+5=21
Step 1: Subtract 5 from both sides.
2x+5−5=21−5
2x=16
Step 2: Divide both sides by 2.
2x /2 = 16 /2
x = 8
Answer:
x = 8
Step-by-step explanation:
2x + 5 = 21
2x = 21 - 5
2x = 16
x = 16/2
x = 8

Samuel has been reviewing his notes on functions in preparation for the next test. He thinks it’s possible in a function for the amount of domain values to be greater than the amount of range values. Is Samuel correct? Explain why or why not.
Answer:
He is incorrect.
Step-by-step explanation:
The range values cannot be greater than the domain values because of the known mathematical fact that all inputs (domain) can only have one output (range). This mathematical fact proves that the range can only be equal to the amount of inputs, not greater. To show why let's look at an example.
Ex:
Inputs: Outputs:
1 2
3 2
6 2
Using that example we can already conclude that the domain values can be greater than the range values because each of the different inputs can have the same outputs as shown in the table above. But the thing with range is you can't have more than one output for the inputs. For example 1 (input) = 2 output and this will always equal 2 no matter what. You cannot have the inputs of 1 and have different outputs 2 and 4. Since you cannot have more than one output for an input it makes the amount of range values impossible to be greater than the domain values.
Hope that helped.

Which statements are always true regarding the
diagram? Select three options.
Omz5 + mz3 = mz4
Omz3 + mz4 + mz5 = 180°
Dmz5 + mz6 =180°
Dm2 + mz3 = mz6
Omz2 + mz3 + mz5 = 180°
Answer:
Step-by-step explanation:
m∠5 +m∠6 = 180° ( the angles form a line)
m∠2 + m∠3 = m∠6 ( exterior angle is the sum of 2 not adjacent angles)
m∠2+m∠3+m∠5= 180° (sum of angles in a triangle is 180°)

The phenotypic ratio of the offspring is 1:3:3:9 i.e., 1 recessive phenotype, 3 seed color dominant, 3 seed shape dominant and 9 seed color and shape dominant.
What is a dihybrid cross?A dihybrid cross is a genetic cross between two individuals that are heterozygous for a given trait.
Am individual is heterozygous when it carries two different alleles or gene variants of a given locus.
In conclusion, the phenotypic ratio of the offspring is 1:3:3:9 i.e., 1 recessive phenotype, 3 seed color dominant, 3 seed shape dominant and 9 seed color and shape dominant.

Water is being pumped into a 12-foot-tall cylindrical tank at a constant rate. • The depth of the water is increasing linearly. • At 1:30 p.M., the water depth was 2.6 feet. • It is now 3:30 p.M., and the depth of the water is 3.8 feet. What will the depth of the water be at 4:00 p.M?
Answer:
The depth will be 4.1 ft
Step-by-step explanation:
Here, we have a linear model to work with
Between 1:30 pm and 3:30 pm, there was a difference of 3.8-2.6 = 1.2 ft on the depth
What we can see there is that in 2 hours, there was a difference of 1.2 ft
So the filling rate per hour will be 1.2ft/2 hours = 0.6 ft/hr
Now, we want to know the depth of the water at 4:00 pm
The difference between 3:30 and 4 pm is 30 minutes = 0.5 h
so by addition;
3.8 ft + 0.5(0.6)
will give the depth of the water at 4 pm
That will be;
3.8 + 0.3 = 4.1 ft
We used 3.8 ft as it is the depth at 3:30 pm
Then we need to add what is topping this after 30 minutes of filling using the constant filling rate and the time

Derek Jeter, the short stop for the New York Yankees, a major league baseball team, played in 159 games in 2012 and hit 15 home runs. If he plays a total of 1272 games in his career, approximately how many home runs will he hit?
[A] Write a proportion that is defined by this situation.
[B] Explain how the cross product is used to solve the problem.
[C] Answer the question.
Answer:
120 home runs.
Step-by-step explanation:
Let x be the number of home runs after playing 1272 games.
We have been given that Derek Jeter, the short stop for the New York Yankees, a major league baseball team, played in 159 games in 2012 and hit 15 home runs.
Let us find the probability of hitting home runs in next game.
To find the total number of home runs Derek will hit in his career, we will use relative probability, which is the ratio of the occurrence of a singular event and the total number of outcomes.
So we can set a proportion as:
Let us multiply both sides of our equation by 1272.
Therefore, Derek Jeter will hit approximately 120 home runs in his career.
In his career, Derek Jeter will probably hit 120 home runs.
What is a proportion?A proportion is an equation that sets two ratios at the same value.
Let x be the number of home runs after playing 1272 games.
And given, Derek Jeter hits 15 home runs in 159 games.
To find the number of home runs he hit in 1272 games,
x = 1272 x 15 / 159
x = 120
And to find the proportion:
15x = 120
x = 120/15
x = 8
We can calculate the Cross Product this way:
cross product with angle and unit vector
a × b = |a| |b| sin(θ) n
Therefore, Derek Jeter will hit approximately 120 home runs in his career.
