Create an equivalent system of equations using the sum of the system and the first equation. −5x + 4y = 8 4x + y = 2

Answer:

A=21

Step-by-step explanation:

4 decilitres= 0.4 litres

8.4/0.4=21

Answer:

$4

Step-by-step explanation:

As, interest = PTR /100

= 100 x 1 x 4/ 100

= $4

Total Interest = $4

Answer:

(x +8) (x - 3)

Step-by-step explanation:

Hope it helps you in your learning process.

Answer:

Not exactly, if a possitive and a negetive are added together the number that was larger will choose its symbol. Say "k" is -3, so -3 + 2 = -1, or if "k" was -1, then -1 + 2 = 1.

Step-by-step explanation:

I hope that makes sense

Answer:

B

Step-by-step explanation:

The answer is B because the slope is [tex]\frac{4}{1}[/tex] and there is no y- intercept

Answer:

A.

Step-by-step explanation:

It starts from 32 on the y-axis and goes up 4 times on x-axis.

Answer:

[tex]9\pi \: \mathrm{ft^2\:or}\: 28.27 \mathrm{\: ft^2}[/tex]

Step-by-step explanation:

The area of a circle is given by [tex]r^2\pi[/tex] where [tex]r[/tex] is the radius of the circle. The diameter is given as [tex]6[/tex] feet, so the radius of this circle is [tex]\frac{6}{2}=3[/tex] feet.

Plugging in our values, we get:

[tex]3^2\pi=9\pi\approx28.27[/tex].

So, we see that both Francie and Jake lives miles from the school. Hence, they both live the same distance from the school.

Answer:

[tex]\angle 1[/tex] and [tex]\angle 3[/tex] are vertical angles and are congruent (have the same measure).

Step-by-step explanation:

[tex]\angle 1[/tex] and [tex]\angle 3[/tex] represent a pair of vertical angles. They are opposite angles to two intersecting lines. Vertical angles are always congruent. None of the other answer choices are implied in the figure.

Step-by-step explanation:

Answer:

36

Step-by-step explanation:

200-20=180

180/5=36

                                                 Table 1

Input (x)               1            3           5            5              9

Output (y)             7           16          19          20           28

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

From Table 1, it is clear that:

Therefore, Table 1 represents a function.

                                                Table 2

Input (x)               0.5          7           7            12            15

Output (y)             7           15          10          23           30

We already know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

From Table 2, it is clear that:

As the input x = 7 is repeated multiple times, thus, the given table 2 does not represent a function.

Therefore,  Table 2 does not represent a function.

Answer: 13x - 14

Step-by-step explanation:

3x + 10x - 14

13x -14

Answer:

13x-14

Step-by-step explanation:

Answer:

0.2 miles

Step-by-step explanation:

From the above question:

2 miles = 10 minutes

Hence:

10 minutes = 2 miles

1 minute = x miles

Cross Multiply

10 minutes × x miles = 2 miles × 1 minute

x miles = 2 miles × 1 minute/10 minutes

x miles = 0.2 mile

Hence in 1 minute it would take her 0.2 miles

Answer:

(1,1)/ one solution

Step-by-step explanation:

The solution is where the lines intersect.

Answer:

Conclusion:

Step-by-step explanation:

Given

We know that the diagonals of a parallelogram bisect each other.

Therefore,

Given RT = x and TP = 5x-28, so

x = 5x-28

5x = x+28

5x-x = 28

4x = 28

divide boh sides by 4

4x/4 = 28/4

x = 7

Thus, the value of x = 7

Similarly,

QT = TS

Given QT = 5y and TS = 2y+12, so

5y = 2y+12

5y-2y = 12

3y = 12

divide both sides by 3

3y/3 = 12/3

y = 4

Thus, the value of y = 4

Conclusion:

Answer:

If its 4 sides need to be equal and 4 angles need to be equal then it is a square.
