Answer:

First, this table is a function because it has no repeating input values

Second, it is increasing in both the x and y

third, since it is increasing in x and y it is a positive correlation( I dont know if you have learned that yet)

Fourth, the output increases by 4 each time the input increases by 1

Answer:

a= -3

Step-by-step explanation:

first distrubute the parenthesis -2(a-3)

-2a+ 6= 12

then move the like terms

6 becomes -6 and subtract to both sides so 6-6 cancels out and you are left with 12-6 which gives you 6

then you have -2a = 6

lastly divide on both sides and you get

-2a÷ -2 (cancels out)

6÷ -2

and the answer is

a= -3

Answer: 96 in2

Step-by-step explanation: This is because u have to mutiple the two bases and the lateral sides to get your area

The surface area of the cube, in inches² is 96in²

The formula for calculating the surface area of a cube is expressed as:

S = 6L²

L is the side length of the cube

Given that L = 4in. Substitute the given parameter into the formula:

S = 6(4)²

S = 6(16)

S = 96in²

Hence the surface area of the cube, in inches² is 96in²

Answer:

n = -7

Step-by-step explanation:

Solve for n:

-3 n - 5 = 16

Hint: | Isolate terms with n to the left-hand side.

Add 5 to both sides:

(5 - 5) - 3 n = 5 + 16

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

-3 n = 16 + 5

Hint: | Evaluate 16 + 5.

16 + 5 = 21:

-3 n = 21

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -3 n = 21 by -3:

(-3 n)/(-3) = 21/(-3)

Hint: | Any nonzero number divided by itself is one.

(-3)/(-3) = 1:

n = 21/(-3)

Hint: | Reduce 21/(-3) to lowest terms. Start by finding the GCD of 21 and -3.

The gcd of 21 and -3 is 3, so 21/(-3) = (3×7)/(3 (-1)) = 3/3×7/(-1) = 7/(-1):

n = 7/(-1)

Hint: | Simplify the sign of 7/(-1).

Multiply numerator and denominator of 7/(-1) by -1:

Answer:

(c+3b)/8 = a

Step-by-step explanation:

c = 8a -3b

Add 3b to each side

c +3b = 8a-3b+3b

c +3b = 8a

Divide each side by 8

(c+3b)/8 = 8a/8

(c+3b)/8 = a

Answer:

Boys : 104

Girls : 65

We know:

For every 8 boys there is 5 girls so the ratio is:

8 : 5

There are 169 total students

We are going to take these students as cookies and how many of them we are going to bake in batches

Step-by-step explanation:

Add 8 and 5 together to find out how many students in each 'Batch' 8 + 5 = 13

Then divide 169 by 13 which equals 13. Now you know how many 'Batches' there are.

To find the answer Multiply 13 by 8 and 5 ;

13 * 8 = 104

13 * 5 = 65

Check the answer:

104 + 65 = 169

Its correct!

Answer:B have it ✅

Step-by-step explanation:

The value of x for the given equilateral triangle is 28.

A triangle having all sides equal and each angle measures 60° is called

an equilateral triangle.

Given that, the measure of each angle in an equilateral triangle is represented by the expression 2x + 4.

We know that each angle in an equilateral triangle measures 60°

Therefore, 2x+4= 60

2x = 56

x = 28

Hence, the value of x is 28.

Answer:

(-13)^2= (15* -11 + -4) = -169

Step-by-step explanation:

Replace all occurrences of + − with a single − . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign

because1 x −1 = −1

(−13)^2=15 x −11 −4

Raise − 13 to the power of 2 .

169=15 x −11 −4

Multiply 15 by −11.

169 = −165 − 4

and finally Subtract 4 from−165.

169 = −169

if its (-13)^2 / (15*-11+-4) as the orginal post did not say divided, the answer would be -1 hope his helps.
