are the two lines 3x - 4=-7 and x + 3y=6 parallel?
Answer:
No because the slopes arent the same (I’m guess it was -4y and not -4)
Step-by-step explanation:
Determine if the relation is a function. In your handwritten work, explain why or why not.
Please and Thank you!!!
Answer:
Step-by-step explanation:
Its not a function. The reason its not a function is because it doesnt pass the vertical line test. You could graph these points physically or you could think about it. The domain is the x value, while the range is the allowed y values. So by having the same x value relate to two different y values, just makes no sense. Imagine the function is x+4 and we are given in that graph that when x equals 6, the y equals 9 and 10. That isnt possible because we know the answer is 10, not 9, it cant be both.
Another way you could prove this is by graphing. If you try to take the slope in that interval where 6 coorelates to two y values. The change in y is 1, but the change in x is 0. When you divide 1/0, your calculator blows up. Try it

What is the probability of picking a multiple of 3?
Write your answer as a fraction in simplest form.
Answer: 3/10!!
Step-by-step explanation: 3 can be divided by 3, 6, and 9. Making them multiples of 3.
The probability of picking a multiple of 3 is 3/10.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Sample space = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
There are ten numbers.
i.e N = 10
Numbers that are multiples of 3 = {3, 6, 9}
There are three numbers.
i.e M = 3
Now,
The probability of picking a multiple of 3.
= M/N
= 3/10
Thus,
The probability of picking a multiple of 3 is 3/10.

Given: Lines p and q are parallel and r is a transversal. Prove: ∠2 ≅ ∠7. Which statements could complete the proof?
Answer:
Angle 2 is congruent to angle 3
Angle 3 is congruent to angle 7
If lines p and q are parallel and r is a transversal. so, ∠2 is congruent to angle ∠3 and ∠3 is congruent to angle ∠7.
How to Identify Transverse and Parallel Lines?From the transverse and parallel line theorem of geometry, we know that:
If two parallel lines are cut by a transversal, then corresponding angles are congruent.
Two lines cut by a transversal are parallel IF AND ONLY IF corresponding angles are congruent.
Lines p and q are parallel and r is a transversal.
Angle 2 is congruent to angle 3
Angle 3 is congruent to angle 7.

f(x)=-4x^2-x-3 Find f(1)
Answer:
f(1)=-8
Step-by-step explanation:
Value of a function
Given a function expressed as y=f(x), where x is the independent variable, and y is the dependent variable, we can give x any desired value in the domain of f.
We are given the function
[tex]f(x)=-4x^2-x-3[/tex]
To find f(1), we replace the variable x for the value 1, and we get:
[tex]f(1)=-4(1)^2-(1)-3[/tex]
[tex]f(1)=-4*1-1-3[/tex]
[tex]f(1)=-4-1-3=-8[/tex]
Thus, f(1)=-8

D and e are complementary. If m\d=5x+3 and m\e=3x-1 what is x
Given:
∠d and ∠e are complementary angles.
m∠d=5x+3 and m∠e=3x-1
To find:
The value of x.
Solution:
If two two angles are complementary angles, them there sum is 90 degrees.
[tex]m\angle d+m\angle e=90^\circ[/tex] (Complementary angles)
[tex](5x+3)^\circ+(3x-1)^\circ=90^\circ[/tex]
[tex]8x+2=90[/tex]
[tex]8x=90-2[/tex]
[tex]8x=88[/tex]
Divide both sides by 8.
[tex]x=11[/tex]
Therefore, the value of x is 11.

8+h/10=1 a true statement?
Answer: 2
Step-by-step explanation:
Anything divided by itself equals one. So, 8 + 2 = 10 and 10/10 = 1
Answer:
h = -70
Step-by-step explanation:
8+h/10=1
Subtract 8 from each side
8-8+h/10=1-8
h/10 = -7
Multiply each side by 10
h/10 * 10 = -7 * 10
h = -70

The measure of the line segment would be 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
It is given that:
JL = 5x + 2
From the line segment we get;
JL = 27 + 3x - 1
Now substitute the value of JL in the equation;
5x + 2 = 27 + 3x - 1
After solving;
5x - 3x = 26 - 2
2x = 24
x = 12
JL = 5x + 2
Plug x = 12
JL = 5(12) + 2
JL = 60 + 2
JL = 62 units
Thus, The measure of the line segment would be 62 units if the JL = 5x + 2 and JL = 27 + 3x - 1 from the line segment.

Step-by-step explanation:
Dana is filling a 1.5 gallon watering can at a rate of 0.75 gallon per minute. What is the domain of the function that represents the volume of water in the can after x minutes?
Answer:
The domain of the function is [tex]Dom \{y\} = [0\,min, 2\,min][/tex].
Step-by-step explanation:
We understand that the watering can is filled at a constant rate, that is:
[tex]y =k\cdot x[/tex]
Where:
[tex]x[/tex] - Filling time, measured in minutes.
[tex]y[/tex] - Watering can volume occupied by water, measured in gallons.
[tex]k[/tex] - Filling rate, measured in gallons per minute.
If we know that [tex]k = 0.75\,\frac{gal}{min}[/tex] and [tex]y = 1.5\,gal[/tex], the final filling time is:
[tex]x = \frac{y}{k}[/tex]
[tex]x = \frac{1.5\,gal}{0.75\,\frac{gal}{min} }[/tex]
[tex]x = 2\,min[/tex]
The domain of the function corresponds to the set of real numbers between zero and final filling time. That is to say:
[tex]Dom \{y\} = [0\,min, 2\,min][/tex]
