Which of these relations is a function?

Answers

Answer: Upper right corner (northeast corner)

Why is this? This is the only relation that passes the vertical line test.

The other choices have situations where we can draw a single straight vertical line through more than one point on the blue curve. That means the graph fails the vertical line test and we do not have a function.

For a function to be possible, any x input must lead to exactly one y output.

B. (4, 8, 12) D. (12, 6, 8)

Answers

Answer: C. (8, 16, 4)

Step-by-step explanation:

Given the following:

Let:

Trucks = T ; Cars = C ; SUVs = S

T =0.5(C + S) - 2 - - - (1)

C = 2T - - - (2)

T + C + S = 28 - - - (3)

T = 0.5(2T + S) - 2

T = T + 0.5S - 2

0 = 0.5S - 2

0.5S = 2

S = 2/0.5

S = 4

From T + C + S = 28

C = 2 T ; S = 4

T + 2T + 4 = 28

3T = 28 - 4

3T = 24

T = 24/3

T = 8

From T + C + S = 28

8 + C + 4 = 28

12 + C = 28

C = 28 - 12

C = 16

Hence, (T, C, S) = (8, 16, 4)

Kaitlyn is making big goods for charity bake sale he places a tray of scones a tray of muffins and a tray of cookies in the oven discounts bake for 15 minutes the muffins bake for 12 minutes and the cookies bake for 10 minutes when one trays done he removes it and replace it with another tray at the same I don't how many minutes after kaylan put the trays in the oven when he 1st remove the scones muffins and cookies at the same time

Answers

Answer:

So:

Counting from a given time t = 0min, we know that:

Each 15 mins she removes the scones

Each 12 mins she removes the muffins

Each 10 mins she removes the cookies.

So when will she remove both at the same time?

Well, this will happen in the smallest common multiple of 15, 12 and 10.

or at LCM(10, 12, 15).

How we find it?

well, in this case is easy.

All the multiples of 10 end with a zero.

So let's find the multiples of 12 and 15 that also end with a zero:

12*6 = 60

15*4 = 60

and

10*6 = 60

So the LCM(10,12,15) = 60.

Another way is by calculating:

10*12*15/(GCF(10,12)*GCM(12,15)*GCM(10,15)

Where GCF = greatest common factor.

Between 10 and 12 is 2.

Between 12 and 15 is 3

Between 10 and 15 is 5.

Then:

10*12*15/(2*3*5) = 60.

This means that 60 minutes after she starts, she will remove the scones, muffins and cookies at the same time.

X^2 - 6x - 7 = 0

Answers

Answer:

x = - 1, x = 7

Step-by-step explanation:

Given

x² - 6x - 7 = 0

Consider the factors of the constant term (- 7) which sum to give the coefficient of the x- term (- 6)

The factors are - 7 and + 1, since

- 7 × 1 = - 7 and - 7 + 1 = - 6, thus

(x - 7)(x + 1) = 0

Equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

x + 1 = 0 ⇒ x = - 1

3=−2 |14s−5| +3 can i get a simple explination im kind of dumb lol

Answers

Answer:

s=5/14

Step-by-step explanation:

cancel equal terms on both sides of the equation

0=-2 x |14s-5|

swap the sides of the equation

-2 x |14s-5|=0

divide both sides of the equation by -2

|14s-5|=0

when the absolute value of 14s-5= 0, then 14s-5=0

move the constant to the right-hand side and change its sign

14s=5

now divide both sides of the equation by 14

s=5/14

When measuring the sides, triangles can be classified as acute, scalene and isoceles

Answers

Answer:

Yes, When measuring the sides, triangles can be classified as acute, scalene, and isosceles

Step-by-step explanation:

In any triangle, there are at least two acute angles

The types of triangles according to their angles are:

Acute-angled triangle ⇒ 3 angles are acuteRight-angled triangle ⇒ 2 acute angles and 1 right angleObtuse-angled triangle ⇒ 2 acute angles and 1 obtuse angle

The types of triangles according to their sides are:

Equilateral triangle ⇒ 3 equal sidesIsosceles triangle ⇒ 2 equal sidesScalene triangle ⇒ 3 different side

You can classify the type of the triangle according to its angle using the measuring of its sides.

If a triangle has sides length a, b, c where c is the longest side

∵ a² + b² > c²

∴ The triangle is an acute-angled triangle

∵ a² + b² = c²

∴ The triangle is a right-angled triangle

∵ a² + b² < c²

∴ The triangle is an obtuse-angled triangle

You can classify the type of the triangle according to its sides using the measuring of its sides.

If a triangle has sides lengths a, b, c

∵ a, b, c have unequal lengths

∴ The triangle is scalene

∵ a and b or a and c or b and c have equal lengths

∴ The triangle is Isosceles

∵ a, b, c have equal lengths

∴ The triangle is equilateral

Yes, When measuring the sides, triangles can be classified as acute, scalene, and isosceles

Answers

yes. the slope is 1.5 so we agree with both of them because 6/4=1.5 and 1.5/1=1.5

The slope of the line is the ratio of the rise to the run, or rise divided by the run. Yes i can agree with both of their statements.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

As we know that the slope of a line will be always same on a given line. If slope triangle A has slope 6/4. Then triangle B will be also have the same slope.

As both triangles are connected to the same line. These two triangles A and B  will have same slopes.

Mai uses Triangle A and says the slope of this line is 6/4.

If we convert fraction 6/4 to decimal we get 1.5 value.

So i agree with both of their statements.

Two angles are supplementary. If one angle measures twice the other, and the number of degrees in the smaller angle.

Answers

Answer:

60 Degrees

Step-by-step explanation:

Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer

[tex]\frac{180}{3} =60[/tex]

Small and large angle are 60° and 120°.

Given that;

Angles are supplementary

Computation:

Assume;

Smaller angle = a

So,

Large angle = 2a

So,

In supplementary

a + b = 180

a + 2a = 180

3a = 180

a = 60

Smaller angle = 60°

Large angle = 2(60)

Large angle = 180°
