Answer:

D.

Step-by-step explanation:

The solution is where the lines intersect which is at the point (3,2).

So the answer is Option D.

The point (3,2) satisfies both equations.

Answer:  The correct option is

(D) (3, 2), because both lines pass through this point.

Step-by-step explanation:  Given that the two lines A and B are represented by the following equations :

Line A: y = x − 1  

Line B: y = −3x + 11

We are to select the correct option that shows the solution to the above system of equations with reason.

The solution to the above system of linear equations will be the point through which both the lines A and B passes.

Now, comparing the values of y from both the equations, we get

x-1=-3x+11\\\\\Rightarrow x+3x=11+1\\\\\Rightarrow 4x=12\\\\\Rightarrow x=\dfrac{12}{4}\\\\\Rightarrow x=3.

And, from first equation, we get

y=x-1=3-1=2.

Thus, the required solution is (3, 2) because both the lines pass through this point.

Option (D) is CORRECT.

Answer:70

Step-by-step explanation:

step 1:add up the angles you know

step 2:subtract the answer (220) from the total angle measure of a square which is 360 then you get 140

step 3: divide 140 by 2 because the two angles on the sides are equivalent and you get 70

What is the answer to this word problem or how would I solve it
USPshnik [31]
Its a simultaneous equation:
lets make "x" the used games and "y" the new ones

4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156

so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24

Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left

48/9 = how many used ones she can buy = 5. something

she can buy 5 used

Between which two consecutive whole numbers does \sqrt{3} 3 ​ lie? Fill out the sentence below to justify your answer and use yo
lyudmila [28]

Answer:

It lies between 5 and 6

Step-by-step explanation:

Two consecutive numbers are numbers that come after each other:

x , x + 1 are consecutive numbers.

3 \sqrt{3} = 3√3 = 5.19615242271

Therefore, from the above calculation, we can see that square root of 3 is a number that is between consecutive numbers 5 and 6
