Answer:

4/5

Step-by-step explanation:

The slope of the line is 4/5.

To find out the slope of a line, you must remember rise over run. Using that, you count up from whenever the line meets an actual whole number, which in this case it is -2, and then count up 4, and then you start counting right to meet the point (3, 4). The number of spaces you go to the right is 5, making the slope 4/5.

Hope this isn't too confusing and that it helps :)

Answer:

Slope is 1/4

Step-by-step explanation:

Slope=Rise/Run=(y2-y1)/(x2-x1)=(9-6)/(5-(-7))=3/12=1/4

Answer:

20 ounces of milk and 3 ounces of cheddar cheese

30 ounces of milk and 4 ounces of cheddar cheese

40 ounces of milk and 5 ounces of cheddar cheese

Step-by-step explanation:

Consider the inequality [tex]25x+200y\geq 1000[/tex]

Here, x denotes ounces of whole milk and y denotes ounces of cheddar cheese.

To write: three different amounts of milk and cheese that a person could consume to meet the recommendation

Solution:

Take [tex]x=20,y=3[/tex]

[tex]25(20)+200(3)\geq 1000\\500+600\geq 1000\\1100\geq 1000[/tex]

So, [tex]x=20,y=3[/tex] satisfy the inequality [tex]25x+200y\geq 1000[/tex]

Take [tex]x=30,y=4[/tex]

[tex]25(30)+200(4)\geq 1000\\750+800\geq 1000\\1550\geq 1000[/tex]

So, [tex]x=30,y=4[/tex] satisfy the inequality [tex]25x+200y\geq 1000[/tex]

Take [tex]x=40,y=5[/tex]

[tex]25(40)+200(5)\geq 1000\\1000+1000\geq 1000\\2000\geq 1000[/tex]

So, [tex]x=40,y=5[/tex] satisfy the inequality [tex]25x+200y\geq 1000[/tex]

Therefore,

three different amounts of milk and cheese that a person could consume to meet the recommendation are as follows:

20 ounces of milk and 3 ounces of cheddar cheese

30 ounces of milk and 4 ounces of cheddar cheese

40 ounces of milk and 5 ounces of cheddar cheese

Answer: The answer is 40

Step-by-step explanation: If you use the formula to find the area of a triangle(A=Bh/2) and plug the number in like so(A=8 * 10) you would get 80 then you would divide the 80 by 2 and get 40

Given parameters:

Charge per month  = $65

Percentage on rent= 6%

Amount paid by Jack per month = $164

Unknown:

Monthly rent on his property = ?

Solution:

  Monthly rent on his property can be found by;

  Amount paid by Jack per month = Charge per month + 6% of monthly rent

Let the monthly rent = x ;

  So;

              164  = 65 + [tex]\frac{6}{100} x[/tex] x

              164 - 65  = [tex]\frac{6x}{100}[/tex]

                   99  = [tex]\frac{6x}{100}[/tex]

                   6x = 9900

                    x = 1650

Monthly rent on his property is $1650

Answer:

8/6 or 1 1/3

Step-by-step explanation:

Step 1:

4 ( 3q - 2 ) = 4q + 2q      Equation

Step 2:

12q - 8 = 4q + 2q      Multiply

Step 3:

12q - 8 = 6q      Combine Like Terms

Step 4:

12q = 6q + 8       Add 8 on both sides

Step 5:

6q = 8      Subtract 6q on both sides

Step 6:

q = 8 ÷ 6     Divide

Answer:

q = 8/6 or 1 1/3

Hope This Helps :)

Answer:

Hi there! The answer is q=4/3.

Step-by-step explanation:

First—Distrubute the 4 on each side of 3q-2. You should get 12q-8 on the left side of the equation.

Second— Combine like terms. You should see the 4q+2q obviously. Since they have the same letters, they should be combined Into 6q.

as a result you should have 12q-8 on the left side and 6q on the right side.

Switch 6q’s place with -8. But make sure you change the signs of negative and positives as you switch.

Now you should have 12q-6q=8.

Combine like terms again which will be 12q-6q Which will become 6q.

Now you should have 6q=8. divide 6 to both sides of the equation.

Since 6/6 = 1, there should be no coefficients stuck on the q.

when 8 is divided by 6, you should get 8/6.

WAIT YOU ARE NOT FINISHED YET!! YOU HAVE ONE MORE STEP AND YOU WILL HAVE ANSWER.

simplify 8/6 top and bottom divided by 2 each, then you should have 4/3.

Comment if you are confused!! :)

Answer:

I think that B is the best answer

Answer:

No

Step-by-step explanation:

Here is a trick... To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

Your graph has an S and the line would go through it 2 times.

Step-by-step explanation:

5-(-2)

5+2 (a minus and a minus together gives a plus)

=7

9+ (-2)

9-2

=7 (a plus and a minus gives a minus)

Yes it will give you the same answer as a minus and a minus together gives a plus and a plus and a minus gives a minus

Answer:

Step-by-step explanation:

Jada would have brought 90 clementines for all those people.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
For 40 people number of clementines be x,
So, as for the proportional relationship.
16 / 36 = 40 / x
x = 40 [36/16]
x = 10[9]
x = 90

Thus, Jada would have brought 90 clementines for all those people.

Answer:

Omg this is the third time i answered this question, The United States is 387.87 times larger than Columbus, Ohio.

Step-by-step explanation:

8.25 times 100000 = 825,000

3.2 times 100000000 = 320,000,000

320,000,000 divided by 825,000 = 387.87

Answer:

m<1=117° by the Vertical Angles Congruence Theorem.

m<2=117° by the Alternate Exterior Angles Theorem.

Step-by-step explanation:

Vertical Angles Congruence Theorem- if two angles are vertical angles, then they are congruent.

Alternate Exterior Angles Theorem- when two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent.

I hope this helps you out!! Have an amazing day :)

From the given diagram

m∠1 = 117° (Vertically opposite angles)

m∠2 = 117° (Corresponding angles)

In the diagram, we have two parallel lines and a transversal intersecting the two lines.

From one of the theorems, when two lines intersect, the opposite angles are equal. This is the vertically opposite angles theorem

In the diagram, angle 1 is opposite to the angle that measures 117°

∴ m∠1 = 117° (Vertically opposite angles)

In the diagram, angle 1 and angle 2 are found at different intersections and on the same side of each of the parallel lines as well as on the same side of the transversal line. Therefore, they are corresponding angles.

From one of the theorems, corresponding angles are equal. That means angle 1 is equal to angle 2

Since, m∠1 = 117°

∴ m∠2 = 117° (Corresponding angles)

Hence, from the diagram

m∠1 = 117° (Vertically opposite angles)

m∠2 = 117° (Corresponding angles)
