the product of a number and 4 increased by 16 is -2

Answers

Answer 1

Let n = the unknown number

"The product of a number and 4" = 4 * n = 4n

"increased by 16" = + 16

Set it all equal to - 2.

4n + 16 = - 2

Subtract 16 from both sides to get constants on one side and variables on the other.

4n = - 2 - 16

Combine like terms:

4n = - 18

Divide both sides by 4 to isolate variable n.

n = - 18 / 4

= - 4 and 2/4 = - 4 and 1/2

The y-value is ten decreased by the square of the x-value

Answers

answer:

y = 10 - x²

step-by-step explanation:

the y value is means the y value is equal to meaning the first part of our equation is y =

10 decreased means 10 minus so the next part of our equation is y = 10 -

the square of the x value means x squared so the last part of our equation is y = 10 -

The required expression is y =  10- x²

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given statement is ,

The y-value is ten decreased by the square of the x-value

So we have two variables x and y.

So square of x = x*x = x²

and, ten decreased by the square of the x-value = 10- x²

Hence we get y is 10- x²

So the expression is

y =  10- x²

Hence,the required expression is y = 10- x²

Problem: A karate team had 6 girls and 9 boys. Then 2 more girls and 3 more boys joined the team. Did the ratio of girls to boys stay the same?Explain.

Answers

The answer would be yes. The way to solve this is by simplifying the first ratio. The first ratio should be girls to boys, which is 6:9. And since ratio can be fractions, 6:9 could be 6/9. Since 6/9 can simplify, you would get 2/3. Now we need to add the 2 girls and 3 boys back into the ratio. The ratio would then look like 8:12. And 8:12 could be 8/12, and 8/12 can be simplify, we get 2/3. So this means that the ratio stayed the same.

The ratio of girls to boys in the karate team remained the same at 2:3, both before and after the new members joined.

Initially, there were 6 girls and 9 boys, creating a ratio of 6 girls to 9 boys, which simplifies to 2:3 when divided by the greatest common divisor, 3. After 2 more girls and 3 more boys joined, the team had 8 girls and 12 boys.

This new ratio also simplifies to 2:3, since both the numerator and denominator can be divided by 4. Therefore, the ratio of girls to boys did not change after the new members joined the team; it remained the same at 2 girls for every 3 boys.

Select all the equations where m= 4 is a solution


Choose 3 answers:

A) 13 = 9 + m

B)7- m = 3

C) 15 = 11m

D) 5 = m + 2

E) 20 divide m =5

Answers

Answer:

A, B, E

Step-by-step explanation:

A) 13=9+m

m= 13-9

m=4 ✔️

B) 7-m =3

m= 7-3

m=4 ✔️

C) 15= 11m

15=11*4

15≠44

D) 5= m+2

If m=4 therefore

5≠4+2

5≠6

E) 20 divide m = 5

20/4 = 5

therefore, m=4 ✔️

Final answer:

By substituting m=4 into each equation, we find that options A) 13 = 9 + m and E) 20 divided by m = 5 are the correct equations where m=4 is a solution.

Explanation:

In mathematics, specifically algebra, we can solve and check equations by plugging in values. You are asked to find the equations where m = 4 is a solution.

Let's substitute m with 4 in each equation:

A) 13 = 9 + m becomes 13 = 9 + 4. Hence, 13 = 13 which is true. B) 7- m = 3 becomes 7 - 4 = 3 so it is incorrect because 3 is not equal to 7 - 4. C) 15 = 11m becomes 15 = 44 which is incorrect. D) 5 = m + 2 becomes 5 = 4 + 2 which is incorrect because 5 is not equal to 6. E) 20 divided by m = 5 becomes 20 divided by 4 equal to 5. So, 5 = 5 is correct.

Therefore, the equations where m=4 is a solution are A) 13 = 9 + m and E) 20 divided by m = 5.

In a triangle the length of two sides are 1.9m and 0.7m. What is the length of the third side, if you know that it should be a whole number?

Answers

Answer:

2

Step-by-step explanation:

A side of a triangle is less than the sum of the lengths of the other two sides and is greater than the positive difference of them.

third side is in between 1.2 and 2.6 but it has to be a whole number so its 2

A possible measure of the third side is 2m (to the nearest whole number)

Using the triangular theorem which states that the measure of the third side of the triangle is less than the sum of the other two sides.

Given the length of the other two sides as 1.9m and 0.7m

Taking the sum

Sum of other two sides = 1.9m + 0.7mSum of other two sides = 2.6m

Since the length of the third side must e less than the sum, hence the required answer must be less than 2.6m.

A possible measure of the third side is 2m (to the nearest whole number)

Let's try an example.

[tex]\frac{1}{13}[/tex] + [tex]\frac{5}{13}[/tex] = ?

Jaycie has a VIP membership to a movie theater, so she pays $27 a year and $6.00 for each movie she sees. Claire doesn’t have a membership, so she pays $8.25 each movie she sees. How many movies would they have to see in a year in order to pay the same amount that year?

Answers

What you would have to do for this problem is set up an equation for a year and equal them out. The equation would be 27+6x = 8.25x.

X = each visit to the movie.

Now all you have to do is solve the equation. Subtract 6x from 8.25x, and get 27=2.25x. Then, divide 2.25 from 27, and you would get your answer, which is 12. So, they would both have to see 12 movies to pay the same amount that year.

To check your work to see if you were right, you would plug in 12 as x, because that is the variable that represents the amount of visits to the movie. For Jaycie, the equation would be 27+6.00(12), and you would get 99, so she would pay $99 in total. For Claire, you would just do 8.25(12), which is also 99. That is how you know your answer is right.

Hope I helped, it would be greatly appreciated if you gave me brainliest if you understood what I explained :)

They'll need to see 12 movies together before they pay the same amount.

Let the number of movies be x

Based on the question given, the equation for Jaycie will be:

= 27 + (6 × x)

= 27 + 6x

The equation for Clarie will be:

= 8.25 × x

= 8.25x

Then, the equation to solve the question will be:

27 + 6x = 8.25x

Collect like terms

27 = 8.25x - 6x

2.25x = 27

x = 27/2.25

x = 12

They will see 12 movies together.

What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 42 degrees

Answers

Isosceles triangle means both base angles are the same. SO,

The given parameters are:

[tex]Base = 42[/tex]

So, we have:

[tex]Vertex + Base + Base = 180[/tex] --- sum of angles in a triangle

Substitute known values

[tex]Vertex + 42+42 = 180[/tex]

[tex]Vertex + 84 = 180[/tex]

There are 62 divisible by the numbers 1, 2, 31, and 62 which is the correct answer that would be an option (D).

What is the divisibility rule?

The divisibility rule states that " Divisible By, implies that when two numbers are divided, the result would be a whole number.

For example, the sum of the digits should be divisible by 3

⇒ 474 : (4+7+4=15, and 15÷3 = 5)

This number is divisible by 3

A. 1, 3, 31, 62

Here 62 is not divisible by 3

B. 1, 2, 3, 31

Here 62 is not divisible by 3

C. 1, 4, 16, 62

Here 62 is not divisible by 4 and 16

D. 1, 2, 31, 62

Here 62 is divisible by 1, 2, 31, and 62

The slope intercept form is y = -x - 4

To find the slope intercept form given a couple of points, start by finding the slope using the slope equation.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-5 - 0)/(1 - -4)

m = -5/5

m = -1

Now we look for the intercept using slope intercept form, our slope and a point.

y = mx + b

Answers

Answer:

A proportional relationship is a relation of the form:

Y = A*X

This means that if we have two variables, X and Y, for each unit that X grows, Y grows A times that.

And notice that the relation:

Y/A = X

is also a porportional relationship

This relationship can be expresed in a graph as a straight line that pases through the origin and has a constant unit of growht (in this case A) that is also called the "slope" of the line.

The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
