Decide whether the given ordered pair is a solution of the system.
x+y=5
X-y= 3
; (4,1)
Is the given ordered pair a solution to the given system?
A. Yes, because (4,1) makes both equations true.
B. No, because (4,1) makes neither equation true.
C. No, because (4,1) only makes the equation x + y = 5 true.
D. No, because (4,1) only makes the equation x-y = 3 true.

Answer: x=-1

Step-by-step explanation:

Since ED and DB are exactly half of EB, we can set ED and DB equal to each other.

x + 4 = 3x - 8

Subtract x from both sides. Add 8 to both sides

12 = 2x

Divide both sides by 2

6 = x

ED = 6 + 4 = 10

ED = DB = 10

EB = ED +DB = 10 + 10 = 20

ED = 10

DB = 10

EB = 20

Answer:

x > 2/3

Step-by-step explanation:

-4(3x - 5) < 2(3x + 4)​

Divide both sides by 2.

-2(3x - 5) < 3x + 4

Distribute on the left side.

-6x + 10 < 3x + 4

Subtract 3x from both sides.

-9x + 10 < 4

Subtract 10 from both sides.

-9x < - 6

Divide both sides by -9. Remember that when you divide both sides of an inequality by a negative number, the inequality sign changes direction.

x > (-6)/(-9)

x > 6/9

x > 2/3

[tex]\textsf{Hey there!}[/tex]

[tex]\text{FIRST step: you have to DISTRIBUTE}[/tex]

[tex]\textsf{4(3x) - 4(-5) = ?}[/tex]

[tex]\mathsf{4(3x)= 12x}[/tex]

[tex]\mathsf{4(-5) = -20}[/tex]

[tex]\mathsf{\underline{= 12x - 20}}[/tex]

[tex]\textsf{NEW EQAUTION}[/tex]

[tex]\mathsf{12x - 20 = -80}[/tex]

[tex]\textsf{SECOND step: ADD by 20 on BOTH of your sides}[/tex]

[tex]\mathsf{12x - 20 + 20 = -80 + 20}[/tex]

[tex]\mathsf{Cancel\ out: -20 + 20\ because\ it\ gives\ you\ 0 }[/tex]

[tex]\textsf{Keep: -80 + 20 because it helps us solve for our answer}[/tex]

[tex]\textsf{NEW EQUATION}[/tex]

[tex]\mathsf{12x = -60}[/tex]

[tex]\textsf{THIRD step: DIVIDE by 12 on BOTH of your sides}[/tex]

The factored form of equation is 9t²(3t-4) - 4(3t+4)

What is factored form of an equation?

A factored form is a parenthesized algebraic expression. In effect a factored form is a product of sums of products … or a sum of products of sums … Any logic function can be represented by a factored form, and any factored form is a representation of some logic function.

According to the question

The factored form of equation :

[tex]27t^3 - 36t^2 - 12t - 16[/tex]

taking common from first two terms and last two terms

9t²(3t-4) - 4(3t+4)

as it cannot be factorized further as it do not have any common terms left

Hence, The factored form of equation is 9t²(3t-4) - 4(3t+4)

I think it is a Convience Sampling.

The type of sampling that Marianne is using is convenience sampling.

Convenience sampling is a non-probability sampling method where individuals are selected based on their availability and willingness to participate in the study.

Here, Marianne surveyed the first 30 students who came into her class, which means that she selected the participants based on their convenience of being there at that particular time.

Convenience sampling is not a random sampling method, and it can introduce bias into the results because the sample may not be representative of the population of interest.

In this case, the sample of students may not represent the entire student population at the school, and the results may not be generalizable to other students.

Thus, the type of sampling that Marianne is using is convenience sampling.

[tex]Explanation:[/tex]

[tex]8x+0.2=48.2[/tex]

Let's start with subtracting 0.2 from both sides of the equation.

[tex]8x+0.2-0.2=48.2-0.2\\8x=48[/tex]

In our second/last step, we will divide both sides by 8.

[tex]\frac{8x}{8}=\frac{48}{8}[/tex]

Let's simplify by dividing 48 by 8.
