[tex]x=3,\:y=-1[/tex]

Step-by-step explanation:

[tex]3x - 4y = 13[/tex]

[tex]5x + 4y = 11[/tex]

isolate x for 3x-4y=13

[tex]\mathrm{Subsititute\:}x=\frac{13+4y}{3}[/tex]

[tex]\begin{bmatrix}5\cdot \frac{13+4y}{3}+4y=11\end{bmatrix}[/tex]

[tex]\frac{65+32y}{3}=11[/tex]

now isolate y for [tex]\frac{65+32y}{3}=11[/tex]

[tex]\frac{65+32y}{3}=11[/tex]

[tex]65+32y=33[/tex]

[tex]32y=-32[/tex]

Divide both sides by 32

[tex]\frac{32y}{32}=\frac{-32}{32}[/tex]

[tex]y=-1[/tex]

[tex]\mathrm{For\:}x=\frac{13+4y}{3}[/tex]

[tex]\mathrm{Subsititute\:}y=-1[/tex]

[tex]x=\frac{13+4\left(-1\right)}{3}[/tex]

  [tex]=\frac{13-4\cdot \:1}{3}[/tex]

  [tex]=\frac{9}{3}[/tex]

Based on the temperatures displayed by Thermometer A and Thermometer B, the thermometer displaying the greater temperature is Thermometer A

The best way to find the thermometer that is displaying the greater temperature is to convert the units of temperature to a single unit so that a proper comparison can be made.

Convert Thermometer B to degrees Fahrenheit. Celsius to Fahrenheit gives:

= (1°C × 9/5) + 32

=  (22°C × 9/5) + 32

= 71.6 degrees Celsius

This means that Thermometer A is displaying the greater temperature.

Answer: 307,000

Step-by-step explanation: Since 451 is less than 500, you want to round down.

Answer: 307,000

Step-by-step explanation: A number rounded to "the nearest thousand", must be multiple of 1000. In this case the value would be 306,000 or 307,000, or 308,000 or 309,000, depending on which of these our given number is closest (nearest) to. 307,495 is less than 307,500 , which is the value halfway between 307,000 and 308,000.

Answer:

(-1, -5) satisfies the inequality and will be the solution to the inequality.

From the attached figure, it is clear that  (-1, -5) is below the line.

Therefore, the correct option is:

''Yes, because 1-1, 5) is on the line​''.

Step-by-step explanation:

Given the inequality

[tex]y\le -\frac{3}{4}x-1[/tex]

substituting (-1, -5)  to check whether it satisfies the inequality or not

[tex]-5\le \:-\frac{3}{4}\left(-1\right)-1[/tex]

[tex]-5\:\le \:\frac{3}{4}-1[/tex]

[tex]-5\:\le -\frac{1}{4}[/tex]

TRUE

Thus, (-1, -5) satisfies the inequality and will be the solution to the inequality.

From the attached figure, it is clear that  (-1, -5) is below the line.

Therefore, the correct option is:

''Yes, because 1-1, 5) is on the line​''.

The distributive property to simplify the expression 7/6 (30 − 18) is (a) 14

From the question, we have the following parameters that can be used in our computation:

7/6 (30 − 18)

When the expression is expanded, we have the following

7/6 (30 − 18) = 7/6 * 30 − 7/6 * 18

Evaluate the products

This gives

7/6 (30 − 18) = 35 − 21

Lastly, we have

7/6 (30 − 18) = 14

Hence the expression when simplified is (a) 14

Answer:

10.14

Step-by-step explanation:

1.69

x 6

------

10.14

The decimal points do not need to line up when multiplying..

1. The 6 on the bottom is multipled by the 9 on top which gets us 54 we write down the 4 and carry the 5.

2. The 6 on the bottom is now multiplied with the other 6 on top which gets us 36 plus the 5 that we carried earlier in the first step which equals 41. 36 + 5 = 41 We write down the 1 and carry the 4.

3. The 6 on the bottom is now multiplied with the 1 on top which gets us 6 plus the 4 that we carried ealier in the second step which equals 10. 6 + 4 = 10

4. So now we have the numbers 1014 but we can't forget about the decimal. Count all the numbers behind the decimal in the top and bottom numbers (if the bottom number doesn't have any numbers behind it, then no need to count), and we get two numbers behind the decimal.

5. When a number has no decimal in between the numbers then the decimal will always be at the end. So now we move the decimal (at the end) two times to the left and get 10.14

Check:

10.14 ÷ 6 = 1.69

Step-by-step explanation:

Angles that form a straight line ( add up to 180 ) are supplementary

angles 1 and 2 / 3 and 4 / 5 and 6 /angles 7 and 8 are all supplementary

Angles 1 and 7 are congruent angles

so angle 2 = 125

Subtract 125 from 180 = 55

180 - 125 = 55 degrees

Answer:

(r o g)(2) = 4

(q o r)(2) = 14

Step-by-step explanation:

Given

[tex]g(x) = x^2 + 5[/tex]

[tex]r(x) = \sqrt{x + 7}[/tex]

Solving (a): (r o q)(2)

In function:

(r o g)(x) = r(g(x))

So, first we calculate g(2)

[tex]g(x) = x^2 + 5[/tex]

[tex]g(2) = 2^2 + 5[/tex]

[tex]g(2) = 4 + 5[/tex]

[tex]g(2) = 9[/tex]

Next, we calculate r(g(2))

Substitute 9 for g(2)in r(g(2))

r(q(2)) = r(9)

This gives:

[tex]r(x) = \sqrt{x + 7}[/tex]

[tex]r(9) = \sqrt{9 +7{[/tex]

[tex]r(9) = \sqrt{16}[/tex]{

[tex]r(9) = 4[/tex]

Hence:

(r o g)(2) = 4

Solving (b): (q o r)(2)

So, first we calculate r(2)

[tex]r(x) = \sqrt{x + 7}[/tex]

[tex]r(2) = \sqrt{2 + 7}[/tex]

[tex]r(2) = \sqrt{9}[/tex]

[tex]r(2) = 3[/tex]

Next, we calculate g(r(2))

Substitute 3 for r(2)in g(r(2))

g(r(2)) = g(3)

[tex]g(x) = x^2 + 5[/tex]

[tex]g(3) = 3^2 + 5[/tex]

[tex]g(3) = 9 + 5[/tex]

[tex]g(3) = 14[/tex]

Hence:

(q o r)(2) = 14
