Is the ordered pair a solution of the equation?
y = x + 16; (-1,-17)
a. yes
b. no

EXPLANATION

Since the vertex is at (-1, -3), the only appropriate option is to translate the function one unit to the left, and again translating 3 units down, with the following form:

g(x) = |x+1| - 3

Therefore, the solution is the last option.

Using positive integers between 1 and 9 and each positive integer at most once,

2 x+ 9 < 3 x + 1

6x+ 4 > 5 x+ 8

To get two constraints so that x = 7 is the only integer that will satisfy both constraints at the same time. Upon analysing it can be seen that to the coefficients of x in eaxh equation shouch be two consecutive number. The coefficient on the lesser than side should be lower than the coeffiecient present on the greater than side.

To make the equation in such a way that only 7 satisfy it, the lesser than sides are added with numbers higher than 7 that is 8 and 9.

Therefore, Using positive integers between 1 and 9 and each positive integer at most once,

2 x+ 9 < 3 x + 1

6x+ 4 > 5 x+ 8

Answer: [tex]x=-\frac{1}{2}, y=\frac{9}{2}[/tex]

Step-by-step explanation:

[tex]5x+7=7x+8\\\\2x=-1\\\\x=-\frac{1}{2}\\\\\implies y=5\left(-\frac{1}{2} \right)+7=\frac{9}{2}[/tex]

Answer:

y = 5x + 7 ---1

y = 7x + 8 ---2

Substitute either one of the equations into the other.

I will substitute 1 into 2.

5x + 7 = 7x + 8

Simplify and solve for x.

2x = -1

x = -1/2

Substitute x into either one of the equations to find y.

I will substitute x into 1.

y = 5(-1/2) + 7

= 9/2

Hence, x = -1/2, y = 9/2

SOLUTION:

Case: Interpreting slopes from linear equations

Method:

V(x) = 20.6 + 2.2x

Compared to

y = mx + b

Where m is the slope and it is being interpreted as the rise for every single run on the line graph.

As it applies,

V(x) = 20.6 + 2.2x

m = 2.2 thousand ie. 2200

It is interpreted as the amount the value increases by each month.

Final answer:

The value of this investment is increasing at a rate of $2200 each month

Answer:

  72 cm²

Step-by-step explanation:

You want the area of a shape consisting of a rectangle and a triangle. The rectangle is 7 cm long and 8 cm high. The triangle has a base of 8 cm and a height of 4 cm.

The area of the rectangle is ...

  A = bh

  A = (8 cm)(7 cm) = 56 cm²

The area of the triangle is ...

  A = 1/2bh

  A = 1/2(8 cm)(4 cm) = 16 cm²

The total area is the sum of the areas of the parts:

  total area = rectangle area + triangle area

  = (56 cm²) +(16 cm²) = 72 cm²

The area of the shape is 72 cm².

__

Additional comment

You can see from the area formula that the area of a triangle is half the area of its enclosing rectangle. That is, the 4 cm high triangle on the right side of the figure effectively adds the area of a 2 cm  wide rectangle with the same base.

The figure's area is equivalent to that of a rectangle 7+(4/2) = 9 cm wide and 8 cm high: (9 cm)(8 cm) = 72 cm², as above.

The type of correlation founded in the study by assessing the work and home life satisfaction measure identically at two occasions, a year apart, is a cross-sectional correlation.

Cross-sectional correlation is a non-experimental research design that uses data collected from a single time point. It is used to generate a static portrait of research variables. As opposed to serial correlation which is a correlation of one variable at different times, cross- sectional correlation is a correlation of two variables at the same time.

In the given study, professor measured the work satisfaction and home-life satisfaction at one time point and repeated it after a year at the second time point. She found a strong correlation between variable at both time points. Hence, it is cross-sectional correlation.

Answer:

Step-by-step explanation:

The relation which represents a function is the mapping diagram.

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable (x-value) to an output variable (y-value).

In this scenario, the same x-value of the given ordered pairs (3, 2) and (3, 4) have the different output variable (y-value) and as such does not represent a function. Similarly, the table of values has the same x-value (-1) which outputs different numerical values.

Based on the ordered pairs and table shown above, we can reasonably and logically deduce that it is only the mapping diagram that represents a function.

Answer:

42

Explanation:

Recall that two triangles are said to be similar if their corresponding angles are congruent and their corresponding sides are in equal proportion.

Given that triangles ABC and XYZ are similar, to be able to determine missing side length, we have to set up proportions as seen below;

Let's cross multiply;

Let's divide both sides of the equation by 5;

So the missing side length is 42

Line c is also perpendicular to line a.

Suppose that c and b are perpendicular. This implies that:

option 1) b and a are the same line or,

option 2) b is parallel to a

Since we know that a and b are different lines, hence, the option 2 is the correct.

Sample space:

Sample space refers the collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”.

Given,

Patty, Quinlan, and Rashad want to be club officers. The teacher who directs the club will place their names in a hat and choose two without looking. The student whose name is chosen first will be president and the student whose name is chosen second will be vice president.

Here we need to find the sample space for the event.

Let us consider,

P represents Patty

Q represents Quinlan

R  represents Rashad

And through the question we have know that, the teacher drawn two card at a time,

So we have consider that the teacher is going to draw out of the hat one first, without replacement, and then draw another one.  

The first chosen one will be the president, and that could be P, Q or R, Now, the chosen second one is the Vice president, and already one has already being drawn, that could only be two fellows.

Therefore, the total of likely outcomes is PQ,QP, PR, RP, QR, RQ, one paired up with either of the two remaining in the hat.

Answer:

(2,-3) See question 10

Step-by-step explanation:

We are given the following expression:

To determine the quotient of the expression we will factor the numerator. To do that we take the Greatest Common Multiple of the denominator.

The denominator is the following expression:

To get the greatest common multiple we need to determine the multiples of the coefficients first.

For 15 we have:

For 30 we have:

For 45 we have:

We notice that the factors that are repeated for each of the numbers are:

The greatest of the repeated factors is 15, therefore, the greatest common factor is 15.

Now, we take the variables that are repeated in the expression and we take the ones with smaller exponents. The variables repeated are:

Of these, the ones with smaller exponents are:

Now, combining the two parts we get that the greatest common factor of the denominator is:

We take out that factor and re arrange the expression, like this:

Now, we cancel out the "xy" and simplify 15/5:

And thus we get the quotient.

We notice that the quotient is multiplied by 3, therefore, if we divide by 3:

We can cancel out the 3 and we get:

Therefore, the quotient is divided by 3.

The variable x is 9 and the two adjacent angles have measures of 117° and 63°, respectively.

Parallelograms are quadrilaterals with two pairs of parallel sides of equal length. According to Euclidean geometry, the measures of two adjacent angles in a parallelogram are supplementary. Thus,

13 · x + 7 · x = 180°

Now we clear the variable x:

20 · x = 180°

x = 9

And the missing angles are:

13 · 9 = 117°

7 · 9 = 63°

The value of the variable x is 9 and the measures of the two adjacent angles are 117° and 63°, respectively.
