Step-by-step explanation

Answer:

The two lines are neither

Step-by-step explanation:

∵ The equations of the lines are

∵ In the 1st equation a = 8 and b = 1

∴ m1 = [tex]\frac{-8}{1}[/tex] = -8

∴ The slope of the 1st line is -8

∵ In the 2nd equation a = 4 and b = 3

∴ m2 = [tex]\frac{-4}{3}[/tex]

∴ The slope of the 2nd line is [tex]\frac{-4}{3}[/tex]

→ By using the facts above

∵ m1 ≠ m2

∴ The two lines are not parallel

∵ m1 × m2 = -8 × [tex]\frac{-4}{3}[/tex] = [tex]\frac{32}{3}[/tex]

∴ m1 × m2 ≠ -1

∴ The two lines are not perpendicular

∴ The two lines are neither parallel nor perpendicular

Answer:

The equivalent function of [tex]sin\left(180^{\circ }+x\right)[/tex] will be: [tex]-\sin \left(x\right)[/tex]

i.e.

[tex]\sin \left(180^{\circ \:}+x\right)=-\sin \left(x\right)[/tex]

Step-by-step explanation:

Considering the function

[tex]sin\left(180^{\circ }+x\right)[/tex]

Solving

[tex]sin\left(180^{\circ }+x\right)[/tex]

Using the angle sum identity:

[tex]\sin \left(s+t\right)=\sin \left(s\right)\cos \left(t\right)+\cos \left(s\right)\sin \left(t\right)[/tex]

[tex]=\sin \left(180^{\circ \:}\right)\cos \left(x\right)+\cos \left(180^{\circ \:}\right)\sin \left(x\right)[/tex]

as

[tex]\cos \left(180^{\circ \:}\right)=\left(-1\right)[/tex]

[tex]\sin \left(180^{\circ \:}\right)=0[/tex]

so

[tex]=0\cdot \:\cos \:\left(x\right)+\left(-1\right)\cdot \:\sin \:\left(x\right)[/tex]

[tex]=0\cdot \cos \left(x\right)-1\cdot \sin \left(x\right)[/tex]

[tex]=0-1\cdot \sin \left(x\right)[/tex]

[tex]=0-\sin \left(x\right)[/tex]

[tex]=-\sin \left(x\right)[/tex]

So, the equivalent function of [tex]sin\left(180^{\circ }+x\right)[/tex] will be: [tex]-\sin \left(x\right)[/tex]

Therefore:

[tex]\sin \left(180^{\circ \:}+x\right)=-\sin \left(x\right)[/tex]

Answer:

113º

(pls mark brainliest if possible)

Step-by-step explanation:

Hexagon has sum of interior angles as 720º

127+85+121+135+139+x=720

607+x = 720

x= 113º

Answer:

B

Step-by-step explanation:

Given

x² + 3x - 5 - (4x² + 3x - 6) ← distribute parenthesis by - 1

= x² + 3x - 5 - 4x² - 3x + 6 ← collect like terms

= - 3x² + 1 → B

Answer:

[tex]-2^{\circ}\text{F}[/tex]

Step-by-step explanation:

Let [tex]x[/tex] be the temperature on the first day

Second day temperature

[tex]x+7[/tex]

Third day temperature

[tex]x+7-10[/tex]

Fourth day temperature was [tex]1^{\circ}\text{F}[/tex]

[tex]x+7-10+6=1\\\Rightarrow x+3=1\\\Rightarrow x=1-3\\\Rightarrow x=-2^{\circ}\text{F}[/tex]

On the first day the temperature was [tex]-2^{\circ}\text{F}[/tex]

Answer:

x = 11, lucky you, this stuff is easy

Step-by-step explanation:

110 - 11 = 99

9 x 11 = 99

99 + 11 = 110

Answer:

x = 11

Step-by-step explanation:

9x + 11 = 110

- Pass the 11 to the other side of the equation (grouping similar terms) and then perform the following operation:

9x = 110 - 11

9x = 99

- Now we have to obtain x by dividing 9 on both sides of the equation:

(9/9)x = 99/9

x = 99/9, which is divisible by 11.

Answer:

30

Step-by-step explanation:

We can ignore the fact they are similar altogether. It's known that all 3 angles of a triangle add up to 180, so:

180=102+48+m

180=150+m

30=m

Answer:

A. 30 degrees

Step-by-step explanation:

They are similar aka the same or congruent and since you know all three angles you just match them up.

Answer:

0.786 L

Step-by-step explanation:

1000 ml to 1 L

(786 ml) / (1000 ml) = 0.786 L

0.786 L liquids of liter did the scientist to use for this experiment

Division is the process of splitting a number or an amount into equal parts.

here, we have,

A scientist used 786 milliliters of an liquid for an experiment.

we know,

1000 ml to 1 L

so, we get,

(786 ml) / (1000 ml) = 0.786 L

Hence, 0.786 L liquids of liter did the scientist to use for this experiment.

Answer:

56% should be the answer

Answer:

Ivette is wrong and by a lot. The spaceship should be 23.59 feet high

Step-by-step explanation:

The relationship between the spaceship's height and width = 184 feet : 78 feet ≈ 92 : 39 ≈ 9.2 : 3.9. This means that for every 3.9 feet wide, the cake should be 9.2 feet high.

In this case, the spaceship is 10 feet wide, so it should be (10 / 3.9) x 9.2 =  23.59 feet high.

When you make scale drawings or scale cakes, you must keep the same proportions as the original model.

Answer:

x = 42º

Step-by-step explanation:

We know that m < UVY is equal to 84º (Given)

We know that < UVY = < SVW (Vertical Angles Theorem)

By substituting in the known values for the anges, we know that:

< UVY = < SVW

84º = 2x

Simplify the equation by dividing by 2 on both sides.

x = 42º

Hope this helps! Let me know if you have any questions!

Solution given:

<UVY=2x[vertically oppisite anglle]

1+1=2

Answer:

9+x=14

Step-by-step explanation:

The x represents the other sister and all the books together would equal 14. The other sister got 5 books!

The equation that represents the number of books bought by the other sister is x + 9 = 14.

Here, we have,

given that,

Two sisters bought together 14 books. One bought 9 books.

To represent the number of books bought by the other sister (x) given that the two sisters bought together 14 books and one sister bought 9 books, we can use the equation:

x + 9 = 14

In this equation, x represents the number of books bought by the other sister.

The equation states that the sum of the number of books bought by the other sister (x) and the sister who bought 9 books is equal to the total number of books bought together, which is 14.

Therefore, the equation that represents the number of books bought by the other sister is x + 9 = 14.
