GIVING BRAINLEST, hi, I need an answer that is 100% correct because this test determines if I'm passing or not, thank you.

Answer:

Step-by-step explanation:

Write in y = mx + b form

here, b ----> y intercept

2y - 2x = 8

     2y = 2x + 8         {Divide the equation by 2}

       [tex]\frac{2y}{2}=\frac{2x}{2}+\frac{8}{2}\\[/tex]

        y = x + 4

y-intercept = 4

Answer:

180°

Answer:

A= 3,B = 2

Hope it helps you

if yes mark me brainliest

Answer:

hence, a = 3

b = 2

Step-by-step explanation:

from the given pair of linear equation we get,

7a + 3b = 27 - ( 1 )

6a + 3b = 24 - ( 2 )

now, subtract equation 2 from equation 1

=》7a + 3b - 6a - 3b = 27 - 24

=》a = 3

now put the value of a in equation 1

=》7a + 3b = 27

=》( 7 × 3 ) + 3b = 27

=》21 + 3b = 27

=》3b = 27 - 21

=》b = 6 ÷ 3

=》b = 2

Step-by-step explanation:

Answer:

A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is called a complete angle.

Answer:

A. 4

B. 2

C. 3

D. 2

Step-by-step explanation:

Multiplication!!! Always remember that a right angle is 90 degrees, also a straight angle is 180 degrees..

Remember like this:

90 x 1 =90

90 x 2 =180

90 x 3 = 270

90 x 4 = 360

Answer:

multiply the base and add the exponents

Answer: Option B, C = 3.

Step-by-step explanation:

Here we have the function:

f(x) = A*cos(x - C)

A is the amplitude, and we can easily see that the amplitude is 2.

Then:

f(x) = 2*cos(x - C)

We also can see that when x = 0, f(x) ≈ -2

This means that:

cos(0 - C) ≈ -1

Cos(C) ≈ -1

Now we can just evaluate in the different options and see which one is the correct option.

Cos(1) = 0.54

Cos(2) = -0.42

Cos(3) = -0.99

Cos(4) = -0.65

The closer option to -1 is when C = 3, then the correct option is option B.

B

Step-by-step explanation:

4729 - 7 is in place of the hundreds, so cut off the rest and make sure, if needed, to round

Answer:

4700

Step-by-step explanation:

round the number up to the nearest hundred if the last two digits in the number are 50 or above.

round the number down to the nearest hundred if the last two digits in the number are 49 or below.

Answer:

[tex]m = 3 \sqrt{12} [/tex]

[tex]n = 6[/tex]

Step-by-step explanation:

n=1/2 of 12 according to the rule:

right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.

so n=12/2=6

and now we will need Pythagorean theorem : the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

so

[tex] {m}^{2} + {n}^{2} = {12}^{2} [/tex]

now lets put numbers on formula

[tex] {m}^{2} + {6}^{2} = {12}^{2} [/tex]

from this formula m=

[tex]m = \sqrt{ {12}^{2} - {6}^{2} } = \sqrt{144 - 36} = \sqrt{108} = 3 \sqrt{12} [/tex]

Answer: 1) 15:25 or 15/25 2) 10:25 or 10/25

Step-by-step explanation: if there are 25 students total and there are 15 boys that means the rest are girls so 25-15 is 10 girls. So the ratio for selecting a boy would be 15:25 or 15/25 and the ratio for selecting a girl would be 10:25 or 10/25

Answer:

87  ?

Step-by-step explanation:

Answer:

A positive slope means that two variables are positively related- that is when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises.

Answer:

  y = -0.03x² +12

Step-by-step explanation:

For "tunnel" or "arch" or "bridge" problems, I like to start with the expression ...

  y = 1 - x²

It has a height of 1 and intersects the x-axis at ±1. This can be scaled to give the appropriate height and x-intercepts.

We want the x-intercepts to be ±20, so we can scale this horizontally by a factor of 20:

  y = 1 -(x/20)²

We want the height to be 12, so we can scale it vertically by a factor of 12:

  y = 12(1 -(x/20)²

  y = 12 -12(x²/400)

  y = -0.03x² +12
