Answer: No, it's not the solution

Explanation:

Let's plug x = -5 into the second equation

y = 2x+10

y = 2(-5)+10

y = -10+10

y = 0

This shows that (-5,0) is the actual solution, instead of (-5,2)

Answer:

c

Step-by-step explanation:

Answer:

Given, 3x−2<2x+1

⇒3x−2x<1+2

⇒x<3orx∈(−∞,3)

The lines y=3x−2 and y=2x+1 both will intersect at x=3 

Clearly, the dark line shows the solution of 3x−2<2x+1.

Answer:

No

Step-by-step explanation:

If you input g = 4 into the inequality, you have

8 - 4 > 4

4 > 4

4 is NOT greater than 4

To be correct, the inequality would have to read:

8 - g ≥ 4

This would be correct because now it reads

4 ≥ 4

4 is greater than OR equal to four

Answer:

28 Dollars

Step-by-step explanation:

80 diveded by 2 is 40

20 percent of 40 is 8

there for each should have tipped 28

Answer:

total tipped = 20% × $80

= $16

total lunch price = $80 - $16

= $64

amount each person pay for tipped

= $16 ÷ 2

= $8

amount each person pay for lunch

= $64 ÷ 2

= $32

total each person pay for lunch and tipped

= $8 + $32

= $40

simplified, it should be -8.5n+8.5

Answer:

4/15

Step-by-step explanation:

They have baked 1/3 + 2/5. To add you need common denominators.

1/3 = 5/15,     2/5 = 6/15

5/15 + 6/15 = 11/15. This is what they baked.

To find what is left, we need to subtract from 1.  1 = 15/15

15/15 - 11/15 = 4/15

Answer:

20

Step-by-step explanation:

Write 25% as 25/100 · Since, finding the fraction of a number is same as multiplying the fraction with the number, we have 25/100 of 80 =         25/100 × 80

Answer:

[tex]x ^ { 4 } - 3 x ^ { 2 } - 10 = 0\\Let, t = x^{2} \\\rightarrow \: t^{2}-3t-10=0 \\\\\\t=\frac{-\left(-3\right)(+/-)\sqrt{\left(-3\right)^{2}-4\times 1\left(-10\right)}}{2} \\t=\frac{3(+/-)7}{2} \\\\So,\\t = 5 \: and \: -2\\\\Then,\\x = \sqrt{5} \: and \: -\sqrt{5}[/tex]

Answer:

The variable x is equal to 10 degrees.

Step-by-step explanation:

A triangle's angles, in total, must equal 180 degrees.

71 + 50 + (6x-1) = 180

71 +50 = 121

121 + (6x-1) = 180

6x - 1 = 59

6x = 60

x = 10

Answer:

142.24$

Step-by-step explanation:

112 = 100% 9x112

/ 100100. = 10.08$

? = 9%

112 = 100% 18x112 /100 =. 20.16$

? = 18%

so.......

112$ + 20.16$ + 10.08$

= 142.24$

Answer:

the area is 20 in

Step-by-step explanation:

3 times 4 is 12. since we used 3 inches out of the 11, we can only multiply the 8 inches with 1. 8 times 1 is 8. 12+8=20.

How to Find the Area of a Rectangle:

A=LW, where L stands for Length and W stands for Width.

In this case, L is 4 cm more than the width, and the width is 10 cm.

Thus, the length is 14 cm.

Multiply 14 by 10:

A=140 cm²

Answer:

A. f + y ≤ 11

17f + 287 ≤ 242

Step-by-step explanation:

[] Let f be football players and v be volleyball players.

-> The total time must be less than or equal to 242 seconds.

-> If football players talked for 17 seconds, we can write it as 17f.

-> If volleyball players talked for 28 seconds, we can write it as 28v.

[] Coming back to the first point I made, the total time must be less than or equal to 242 seconds.

-> 17f + 28v ≤ 242

[] This is going to be a part of our system of inequalities

-> Because of this, we rule out the following options.

B & D - the football players talk for 17 seconds, not the volleyball players

C ​ - not less than or equal too, only less than

[] This leaves us with the option of A.

-> The first part of it also works. If 11 players can talk to the crowd, then the total of f and v must be equal too or less than 11.

Answer:

Nonexistent

Step-by-step explanation:

The constant of proportionality k is given by k=y/x

We have three examples:

1. x=-3, y=1 (k=-1/3)

2. x=-1, y=3 (k=-3/1)

3. x=3, y=-1 (k=-1/3)

Because the constants are inconsistent, the answer is the last option, Nonexistent.
