Answer:

(a) 9a + 2

(b)  a = 5

Step-by-step explanation:

Perimeter of a triangle = sum of sides

=

2a + 1     +
3a + 2    +
4a  - 1
----------

9a + 2   Answer (a)

If perimeter = 47 , then 9a + 2  =47

Subtract 2 from both sides

==> 9a = 47 -2

9a = 45

a = 45/9

a = 5

Points of the triangle ABC after rotating counter-clockwise 90° and translation of [(x+2),(y-5)] will be a triangle XYZ which has points of XYZ, X(6,-7), Y(2,-4), and Z(-5,-8).

Translations are of 4 types they are rotation, dilation, translation and reflection.

We know when the rotation of 90° counter-clockwise takes place we switch the coordinates (x,y) to (y,x) and make x negative which is (y,-x).

Given a triangle ABC with points A(2, 4), B(-1, 0), and C(3, -7) rotated 90° to form another triangle XYZ.

∴ Points of triangle XYZ will be X(4,-2), Y(0,1), and C(-7,-3).

Now we translate these points by [(x+2),(y-5)].

∴ Points of triangle XYZ will be X(6,-7), Y(2,-4), and Z(-5,-8).

Step-by-step explanation:

Using probability we can say that the event that Gavin rolls an even number on a number cube is as likely as not.

Probability is the study of chance. The likely chance that an event can occur in a random experiment written as a fraction is called probability.

Probability of a event is calculated as the ratio of the favorable outcomes of an event to all the possible outcomes of the event.

Given as experiment: A number cube is rolled by Gavin.

Event : An even number comes up on the face of the cube.

Favorable outcomes : {2,4,6} = 3 outcomes

Total outcomes or sample space: {1,2,3,4,5,6} = 6 outcomes

Probability that an even number comes up:3/6=1/2

Probability that an even number does not come up=1-1/2=1/2

From the above probabilities we see that :

P(even)=P(not even)=1/2

Hence the Gavin rolls an even number is as likely as not likely.

Step-by-step explanation:

Given,

No. of cameras that Gretta has : 103

No. of Cameras she misplaced : 75

1 full box contains 1 camera each

No. of full boxes that she can ship:

= No. of Cameras she has - no. of cameras she misplaced.

= 103-75

= 28

Therefore, the no. of full boxes that Gretta can ship is 28.

the equation of the line that is parallel to the line - x + 2 y = 7 is - x - y + 7 = 0.

We know that, if the lines are parallel, then their slopes are equal.

We have the line:

- x + 2 y = 7

Slope = - 1

Now, we have the point ( 4, 3)

So, the equation of the line will be:

y - y₁ = m ( x - x₁ )

Substituting the values, we get that:

y - 3 = - 1 ( x - 4 )

y - 3 = - x + 4

x + y - 3 - 4 = 0

x + y - 7 = 0

- x - y + 7 = 0

Therefore, the equation of the line that is parallel to the line - x + 2 y = 7 is - x - y + 7 = 0.

Finding the equation of the parabola, it is found that the height of the diving board is of 24 feet.

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

From the maximum height, it is found that the vertex is at (1,25), hence:

h = 1, k = 25.

Hence:

y = a(x - 1)² + 25.

You hit the water 6 feet from the diving board, hence y(6) = 0, meaning that we use it to find a as follows:

0 = a(6 - 1)² + 25

25a = -25.

a = -1.

Hence:

y = -(x - 1)² + 25.

The height of the diving board is y(0), hence:

y = -(0 - 1)² + 25 = -1 + 25 = 24 feet.

Answer:

7 ounces

Step-by-step explanation:

You divide 28 by 4 which would equal to 7 ounces per batch.

Elizabeth used 7 ounces of vinegar to make 1 batch of salad dressing.

Given that Elizabeth uses 28 ounces of vinegar to make 4 batches of salad dressing.

We need to determine the rate of change for this situation.

To find the number of ounces of vinegar Elizabeth used to make 1 batch of salad dressing, we need to divide the total amount of vinegar (28 ounces) by the number of batches (4).

The rate of change for this situation is the amount of vinegar used per batch.

Let's calculate it:

Vinegar used per batch = Total vinegar used / Number of batches

Vinegar used per batch = 28 ounces / 4 batches

Vinegar used per batch = 7 ounces

So, Elizabeth used 7 ounces of vinegar to make 1 batch of salad dressing.

The y-intercept of the given line is -1/2

Y-Intercept means the line making an intercept on the y-axis where the value of x will be 0.

In simple terms, the Y-intercept of any line can be found by making x = 0

The equation of the line given is

20x + 20y = -10

So to find the y-intercept, let us keep x = 0

Thus, the equation becomes

20(0) + 20y = -10

0 + 20y = - 10

20y = -10

y = -10/20

y = -1/2

y = -0.5

The answer need to be in proper fraction as said in the question,

Thus y = -1/2

Step-by-step explanation:

Answer:

-9.5, -7, 5

Step-by-step explanation:

We need to make this a readable function. We will change it to slope-intercept form, y = mx + b. to do this, we must isolate the variable y.

-5x + 2y = -19
-5x + 2y + 19 = -19 + 19
-5x + 2y + 19 = 0
-5x + 2y - 2y + 19 = -2y
-5x + 19 = -2y
We are solving for positive y, so we will flip all signs in the equation.
5x + - 19 = 2y
5x/2 - 19/2 = 2y/2
2.5x - 9.5 = y
y = 2.5x - 9.5

There's our y = mx + b. We now need to solve for each ordered pair.

y = 2.5(0) - 9.5
y = -9.5
(0, -9.5)

y = 2.5(1) - 9.5
y = 2.5 - 9.5
y = -7
(1, -7)

2.5x - 9.5 = 3
2.5x - 9.5 + 9.5 = 3 + 9.5
2.5x = 12.5
2.5x/2.5 = 12.5/2.5
x = 5
