Answer:

only (-4,0) is a reasonable solution.

Step-by-step explanation:

In order to see which ones are reasonable we need to apply the points to the system and check if they make both equations valid at the same time.

y = -x - 4

y = x² + x - 12

For (-4, 0):

0 = -(-4) - 4 -> 0 = 4 -4 -> 0 = 0 (valid)

0 = (-4)² - 4 - 12 -> 0 =  16 - 16 -> 0 = 0 (valid)

For (-3, -1):

-1 = -(-3) -4 -> -1 = 3 -4 -> -1 = -1 (valid)

-1 = (-3)² -1 - 12 -> -1 = 9 -13 -> -1 = -4 (invalid)

For (2, -6):

2 = -(-6) - 4 -> 2 = 6 -4 -> 2 = 2 (valid)

2 = (-6)² -6 -12 -> 2 = 36 -18 -> 2 = 18 (invalid)

Therefore only (-4,0) is a reasonable solution.

Answer:

187 cm^2

Step-by-step explanation:

Area of a parallelogram is base times height. 17 cm is the base and 11 cm is the height so, 17 cm times 11 cm equals 187 cm^2.

Answer:

[tex]\frac{79}{12}[/tex] or 6[tex]\frac{7}{12}[/tex] gallons of gas.

Step-by-step explanation:

First, you have to convert both of your mixed numbers into a improper fractions.

2 [tex]\frac{1}{4}[/tex] = 9/4

4 [tex]\frac{2}{6}[/tex]   = 26/6

Second, find the greatest common multiple of the denominators of both. In this case, it would be 12.

Then find the number that the first improper fraction's denominator would be multiplied by to get the GCM.  Multiply both the nominator and the denominator by that number.

4 would need to be multiplied by 3 to get 12. So we multiply 9/4 by 3/3. We would get 27/12.

Repeat that for the second fraction's denominator.

6 would need to be multiplied by 2 to get 12. So we multiply 26/6 by 2/2. We would get 52/12.

Then add both fractions together.

[tex]\frac{27}{12}+\frac{52}{12}[/tex] [tex]=\frac{79}{12}[/tex]

If you need to, simplify.

[tex]\frac{79}{12} = 6\frac{7}{12}[/tex]

Hope that helped!

Answer:

≈ 7.07

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 7, - 2)

d = [tex]\sqrt{(-7-0)^2+(-2+1)^2}[/tex]

   = [tex]\sqrt{(-7)^2+(-1)^2}[/tex]

   = [tex]\sqrt{49+1}[/tex]

   = [tex]\sqrt{50}[/tex] ≈ 7.07 ( to the nearest hundredth )

Answer:

y=-2x-2

Step-by-step explanation:

Slope: -4-2/1-(-2)=-6/3=-2

Equation: y=-2x+b

Substitute: 2=-2(-2)+b

2=4+b

b=-2

Therefore, y=-2x-2

I hope this helped and have a good rest of your day!

Answer:

30 ft

Step-by-step explanation:

[tex]3 \frac{3}{4} = \frac{15}{4} \\15*2=30[/tex]

Answer:

30 feet

Step-by-step explanation:

If each 1/4 in is equal to 2 feet, then you can find out how many in per feet, by dividing 2 by 1/4, to get 8. You can then multiply 8 by 3 3/4 to get the amount of feet that the living room is if it measures 3 3/4 in on the floor plan.

Answer:

The answer is 20%.

Step-by-step explanation:

10/50= 10 divided by 50=.2

.2 times 100 (because percentages are out of 100) = 20

20% is your answer

For A:

You add the probabilities to get the answer to A: = .75, or 3/4

Note that the probability of ALL THREE of them hitting would be 1/3 x 1/4 x 1/5.

For B:

2/3 and 3/4 is the probability of the other two people MISSING (the remainder of 1/3, 1/4)

1.0 = 100% chance to hit the target, so 1.0 x 2/3 x 3/4 = 1/2

Mark's chance of hitting is 1/5, so do 1/2 x 1/5, = 1/10

Answer: y= -0.5+8

Step-by-step explanation:

Any line that is perpendicular to a line is the opposite and inverse.

Ex. for a line to be perpendicular to 2, the reverse would be -2 and the opposite is -1/2.

Now we need to focus on the b in y=mx+b.

To do that, we plug in 4 as y and -2 in x to find b.

4=2(-2)+b

4=-4+b

And we find that b is 8.

So in conclusion, y=-0.5+8

Answer:

A

Step-by-step explanation:

The largest angle will be the angle that is opposite to longest side.

Longest side is AB = 18 cm. So, opposite angle of side AB is ∠C

Sides from largest to smallest : AB   >   AC   > BC

angles form largest to smallest: ∠C  >  ∠B   >   ∠A

Answer:

I believe the answer is 1

Step-by-step explanation:

Answer:

The answer is either 4 or 1. ( I am quite sure of it ).

Step-by-step explanation:

Because I've got it in my maths book

Right triangle, Pythagorean Theorem:

c² = a² + b²

a=8, b=9

c² = 8² + 9²  = 64 + 81 = 145

c = √145 inches

That's the exact answer but they want us to ruin it with an approximation.

c ≈ 12.041594578792296 inches

Answer: 12

Answer:

x = 7°

<GDH = 112°

<FDH = 192°

<FDE = 135°

Step-by-step explanation:

If DE bisects <GDH this means that <GDE = <EDH

Given <GDE = (8x+1)° and <EDH = (6x+15)° then;

8x+1 = 6x+15

8x-6x = 15-1

2x = 14

x = 7°

Since <GDH = <GDE + <EDH

<GDH = 8x-1+6x+15

<GDH = 14x+14

<GDH = 14(7)+14

<GDH = 98+14

<GDH = 112°

For <FDH,

Note that sum of angle on a straight line is 180°

<FDH = <FDG + <GDE + <EDH

<FDH = <FDG + <GDH

<FDG = 180-(43+8x+1)

<FDG = 180-44-8x = 136-8x

<FDH = 136-8x+112

<FDH = 248-8x

<FDH = 248-8(7)

<FDH = 248-56

<FDH = 192°

For <FDE;

<FDE = <FDG + <GDE

<FDE = 136-8x+8x-1

<FDE = 135°

Answer:

What kind of math are you doing in middle school?

Step-by-step explanation:

Answer:

after 272 mins

Step-by-step explanation:

make it into two linear equations y=.19x and y=29.95+.08x

The equation would be x² + x = 42 which represents "the sum of a number and its square is 42". The correct answer would be an option (A).

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

We have been given that the sum of a number and its square is 42.

Let's assume the required number would be x

According to the given question, translate the phrase into an algebraic form:

The number = x

The number's square = x²

Thus, the sum of a number and its square is 42 will be as:

⇒ number + number's square = 42

⇒ x +  x² = 42

Therefore, the equation would be x² + x = 42 which represents "the sum of a number and its square is 42".

Hence, the correct answer would be option (A).
