3x-y=0
2x+y=-10
Answers
Answer:
(-2, -6)
Step-by-step explanation:
Given the simultaneous equation
3x-y=0 ... 1
2x+y=-10 ... 2
Add both equations to eliminate y
3x + 2x = 0 - 10
5x = -10
x = -10/5
x = -2
Substitute x = -2 into 1
3(-2)- y = 0
-6 - y = 0
-y = 0+ 6
-y = 6
y = -6
Hence the coordinate (x, y) is (-2, -6)

Liam wants to treat some friends to lunch. He has $50 and knows that lunch will cost $8 per person. For how many people can Liam buy lunch?
A
Liam can buy lunch for 7 or fewer people, including himself.
B
Liam can buy lunch for 7 or more people, including himself.
C
Liam can buy lunch for 6 or fewer people, including himself.
D
Liam can buy lunch for 6 or more people, including himself.
Answers
Answer:
C
Step-by-step explanation:
8 x 6 would equal 48, which results in not having enough money to buy lunch for more people.
Answer:
the answer should be c
Step-by-step explanation:
let's do a equation for this problem.
8x = 50
/8 /8
x = 6.25
x represents the amount of friends. we divide 8 by both sides to isolate x by itself.
since the final result gives us a decimal, we have to round it to the nearest whole number. it's not possible to have a decimal amount of friends. it should be 6. it cannot be 7 if you are wondering because 7 is bigger than 6.25. there's no way there can be 7 friends when there is a limit amount of 6. therefore, the answer is c.

Answers
Answer:
Bushes are $9.
Bonsai trees are $32.
Step-by-step explanation:
Bushes are b and bonsai trees are t.
15b + 8t = $391
9b + 5t = $241
15b + 8t = $391 × 3 and 9b + 5t = $241 × 5
= 45b + 24t = $1173 and 45b + 25t = $1205
(45b + 24t = $1173) - (45b + 25t = $1205)
t = 1205 - 1173
t = $32
Apply to 15b + 8t = $391.
15b + 32 × 8 = $391
15b = $391 = 32 × 8
15b = $391 - 256
15b = $135
x = ($135 ÷ 15) = $9

The area of the hardscape is 3x^2 + 13x + 4. what is the length and width of the hardscape
Answers
Answer:
[tex](3x+1)[/tex]
[tex](x+4)[/tex]
Step-by-step explanation:
Assuming that the given surface is two-dimensional, one can simply factor the given polynomial to find the dimensions of the surface.
[tex]3x^2 + 13x + 4[/tex]
Just by looking at the polynomial, it is fairly obvious that the factors are;
[tex](3x+1)(x+4)[/tex]
One can check this by distributing, multiply every term in one of the parenthesis by every term in the other. Then combine like terms,
[tex]3x^2 + 12x + x + 4\\\\3x^2 + 13x + 4[/tex]
Without further information, it is impossible to determine which is the length, and which is the width, one just knows that the dimensions of the surface are;
[tex](3x+1)\\\\(x+4)[/tex]

Serge was curious if a sample third quartile was an unbiased estimator of a population third quartile. He started with a large normally distributed population of test scores whose third quartile was Q3=80 points. He then took a random sample of 6 tests and calculated the third quartile of the sample. He replaced those tests and repeated this process for a total of 40 trials. His results are summarized in the dot plot below, where each dot represents the third quartile from a sample of 6 tests.

Sample third quartile appears to be an unbiased estimator of the population third quartile.
