What is the slope of the line represented by the equation -52 + 2y = 10?

Answers

Answer:

5/2

Step-by-step explanation:

Use PEMDAS to solve the equation in y=mx+b form.

Add 5x on each side of the = sign  (which cancels on left side, and add on right)

Your equation should look like this: 2y=5x+10

Next, you're going to divide the whole equation by 2, to get y by itself

which equals y=5/2x+10

M=slope

For the following equation, find a solution for the variable. Show all of your work and use complete sentences to explain the solving process that you used to find a solution for the equation. Be sure to include at least two terms from the word bank.

6 = 3 x - 9

Answers

Answer:

x=5

Step-by-step explanation:

solution;

6=3x-9(carry alike terms to the same side that'd be +6-9)

+9+6=3x

15=3x(divide both sides by 3)

5=x

(thanks,sorry and welcome)

The solution to the given equation 6 = 3x - 9 would be variable x = 5.

What is the equation?

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

To determine a solution for the variable in equation 6 = 3x - 9, we can begin by isolating the variable on one side of the equation. To do this, we can add 9 to both sides, giving us:

6 + 9 = 3x

This simplifies to:

15 = 3x

The next step is to divide both sides of the equation by 3, which will give us the value of x.

15/3 = 3x/3

Simplifying we get

5 = x

Thus, the solution for the variable is x = 5.

what is the greatest three-digit multiple of 33 that can be written using three different digits?

Please help me!!!

Answers

Answer:

957

Step-by-step explanation:

The largest three-digit multiple of 33 * 30 is 990, which uses only two different digits. Now we work backwards: Subtracting 33 once gives 990-33=957, which has three different digits. Therefore, our answer is 957

957 is the greatest three-digit number which is multiplied by 33.

What are digits?

A numerical digit is a single sign that can be used alone or in combination to denote a number in a positional numeral system.

A digit is a component of a set that, when put together, forms a numerical system.

Examples of digits include 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

If we multiply 33 by 31

It gives 1023 which is a four-digit number.

Now trying to multiply less than 31

By 30

33 × 30 = 990 but here two digits are the same.

By 29

33 × 29 = 957 and all three are different.

Hence "957 is the greatest three-digit number which is multiplied by 33".

Answers

Answer:

(1,4)

Step-by-step explanation:

Answer: x = 1, y = 4

Steps: 3y + 4x = 16,  -2x + y = 2

Isolate y for 3y + 4x = 16:   y = (16 - 4x ÷ 3)

Substitute y into the other equation (-2x + y = 2):   -2x + (16 - 4x ÷ 3) = 2

Simplify: 16 - 10x ÷ 3 = 2

Isolate x for 16 - 10x ÷ 3 = 2:   x = 1

Substitute x = 1 into  y = (16 - 4x ÷ 3):  y = 16 - 4x · 1 ÷ 3

y = 4, x = 1

Answers

Answer: 5√10.

Step-by-step explanation:

250 is split into its prime factors as 2 * 5 * 5 * 5 which implies √250 = √(2 * 5 * 5 * 5). Now we can simplify this further by pulling out the number which is multiplied to itself. This gives √250 = 5 * √(2 * 5) = 5√10. Therefore the square root of 250 is √250 = 5√10.

The distance between two towns is 130 kilometers. There are approximately 8 kilometers in 5 miles.

Which measurement is closest to the number of miles between the two towns?

Please Give A Good Answer Ill Give Brainest And Extra Points ​

Answers

Answer: 81 miles

Step-by-step explanation:

From the question, we are informed that the distance between two towns is 130 kilometers and that there are approximately 8 kilometers in 5 miles.

The measurement that is closest to the number of miles between the two towns goes thus:

Firstly, we need to divide 130 kilometers by 8 kilometers. This will be:

= 130/8

= 16.25

Then, we multiply 16.25 by 5 to get the number of miles between the two towns. This will be:

= 16.25 × 5 miles

= 81.25 miles

= 81 miles

Given m<12= 121 and m<6= 75, find the measure of each missing angle.

Answers

Answer/Step-by-step explanation:

Given:

m<12 = 121°

m<6 = 75°

a. m<1 = m<6 (vertical angles)

m<1 = 75° (substitution)

b. m<12 = m<1 + m2 (alternate exterior angles)

121° = 75° + m<2 (substitution)

121° - 75° = m<2 (subtraction property of equality)

46° = m<2

m<2 = 46°

c. m<1 + m<2 + m<3 = 180° (angles on a straight line)

75° + 46° + m<3 = 180° (substitution)

121° + m<3 = 180°

m<3 = 180° - 121° (subtraction property of equality)

m<3 = 59°

d. m<4 = m<3 (vertical angles)

m<4 = 59° (substitution)

e. m<5 + m<4 + m<6 = 180° (angles on a straight line)

m<5 + 59° + 75° = 180° (substitution)

m<5 + 134° = 180°

m<5 = 180° - 134° (Subtraction property of equality)

m<5 = 46°

f. m<7 = m<12 (vertical angles)

m<7 = 121° (substitution)

g. m<8 = m<4 (vertical angles)

m<8 = 59° (substitution)

h. m<9 = m<6 (Alternate Interior Angles)

m<9 = 75° (substitution)

i. m<10 + m<9 = 180° (Linear Pair)

m<10 + 75° = 180° (substitution)

m<10 = 180° - 75° (Subtraction property of equality)

m<10 = 105°

j. m<11 = m<8 (vertical angles)

m<11 = 59° (substitution)

k. m<13 = m<10 (vertical angles)

m<13 = 105° (substitution)

l. m<14 = m<9 (vertical angles)

m<14 = 75° (substitution)
