Answer:

y = 6x - 2

Step-by-step explanation:

Given that , A line's slope is 6, and its y-intercept is -2. And we need to write the equation in slope intercept form. We know slope intercept form as,

y = mx + C

Where ,

Hence here , on substituting the respective values , we have

⇒ y = mx + C

⇒ y = 6(x) + (-2)

⇒ y = 6x -2

Answer:

Isosceles triangle basically has two equal sides and angles opposite to these equal sides are also equal.Therefore

50° = 2x°

50/2 = x

25 = x

There fore value of x is 25.

so,angle B = 2 × 25

hence angle B is 50

That's all i can solve, I'm also kinda stuck.

hope this helped

Answer:

J=40º, K=60º, H=80º

Step-by-step explanation:

since all angles of a triangle add up to 180º, we can make an eqaution.

3x+2x+4x=180

9x=180

x=20

J=2x=20x2=40º

K=3x=20x3=60º

H=4x=20x4=80º

Answer: 90 stands

Step-by-step explanation:

Mistake was made in question. It should be, ''...which accounts for /...''

There are 30 stands and this translates to 1/3 of the total stands.

Assume the number of total stands is x:

1/3 *  x = 30

x = 30 ÷ 1/3

x = 90 stands

Answer:

1.8 weeks

Step-by-step explanation:

The number of weeks it takes for consuming the 3 gallons of milk is as follows:

It is given that the total of 10 gallons of milk drink for every 6 week i.e. 5 by 3

Now in order to determine the weeks we have to reciprocal the ratio i.e. 3 by 5

Now for 3 gallons it would be

[tex]= \frac{3}{5}\times 3[/tex]

= 1.8 weeks

Answer:

Now 7 remains without a pair and therefore 7 should be multiplied to 112 to make it a perfect square. Similarly 28 should be multiplied to 784 to make it a perfect cube.

Step-by-step explanation:

112 = 2⁴ * 7.

Next power after 2⁴ with a cube power = 2⁶.

Next power after 7 with a cube power = 7³.

Therefore k = 2² * 7² = 196.

Answer:

x= -1/3

Step-by-step explanation:

In the picture attached. if still doubting the answer, check by Substituing the value of x in the equation given.

The required solution to the given equation -3.1x + 7 - 7.4x = 1.5x - 6(x -3/2) is x = -1/3.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question:

-3.1x + 7 - 7.4x = 1.5x - 6(x -3/2)

Apply the distributive property of multiplication,

-3.1x + 7 - 7.4x = 1.5x - 6x  -3 × -3

-3.1x + 7 - 7.4x = 1.5x - 6x + 9

Rearrange the like-wise terms and apply the arithmetic operation,

-3.1x - 1.5x + 6x - 7.4x = -7 + 9

-6x = 2

x = -2/6

Apply the division operation,

x = -1/3

Thus, the required solution to the given equation -3.1x + 7 - 7.4x = 1.5x - 6(x -3/2) is x = -1/3.

Answer:

5 minutes or 1/12 of an hour.

Step-by-step explanation:

3/4 of an hour is 45 minutes.

2/3 of an hour is 40 minutes.

45-40 = 5 minutes or 1/12 of an hour.

Answer:

Each pen costs $6

Step-by-step explanation: $40 total -$10 from the book=$30 left.

$30 left divided by 5 pens = $6 each pen.

Answer: $6

Step-by-step explanation:

This is because you got a book for $10 so you would first minus 10 for the $40 you have and then you have $30 dollars left and 6 x 5 is 30 so then when you add back 10 and the 30 dollars you get the total amount of money.

Answer: Y = 2/3x - 14/3

Answer:

2/3

Step-by-step explanation:

y+2=2/3 (x-4)

1. multiply parentheses (y+2=2/3x-8/3

2. subtract 2 from both sides (y=2/3x-2/3

3. 2/3x is the slope

Answer:

5(9x + 2y + 10)

or

x = 0

y = -5

Step-by-step explanation:

If you are just factoring this, you will factor a 5 out from everything.

5(9x + 2y + 10)

or if you are trying to solve just isolate one of the variables and then substitute it into the original equation

45x + 10y = 50

10y = 50 - 45x

y = 5 - 4.5x

45x + 10(5-4.5x) + 50

45x + 50 - 45x + 50

x=0

45(0) + 10y + 50

0 + 10y + 50

10y + 50

10y = -50

y = -5

and it would be x = 0 and y = -5

Answer:

The equation of the parabola is (x - 4)² = -16(y - 1)

Step-by-step explanation:

The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where

∵ The focus of the parabola is (4, -3)

∵ The focus is (h, k + p)

∴ h = 4

∴ k + p = -3 ⇒ (1)

∵ It has a directrix of y = 5

∵ The directrix of the parabola is y = k - p

∴ k - p = 5 ⇒ (2)

→ Add equations (1) and (2) to find k and p

∵ (k + k) + (p - p) = (-3 + 5)

∴ 2k + 0 = 2

∴ 2k = 2

→ Divide both sides by 2

∴ k = 1

→ Substitute the value of k in equation (1)

∵ 1 + p = -3

→ Subtract 1 from both sides

∴ 1 - 1 + p = -3 - 1

∴ p = -4

∵ The form of the equation of the parabola is (x - h)² = 4p(y - k)

→ Substitute the values of h, k, p in it

∴ (x - 4)² = 4(-4)(y - 1)

∴ (x - 4)² = -16(y - 1)

∴ The equation of the parabola is (x - 4)² = -16(y - 1)

Constant of variation for given quadratic equation is 2/3

Correct option is a.

The ratio between two variables in a direct variation or the product of two variables in an inverse variation.

In the direct variation equations = k and y = k x,

and the inverse variation equations x y = k and

k is the constant of variation.

Given,

quadratic equation,

15y = 10x²

y = (10/15)x²

y = (2/3)x²

Comparing it with general form y = kx²

k = 2/3

Hence, 2/3 is constant of variation for the quadratic equation.

Answer:

10 minutes would be 120 candy bars.

1 minute would be 12 candy bars.

7 minutes would be 84 candy bars.

Step-by-step explanation:

For 10 minutes you multiply 60 times 2, which would be 120 candy bars.

For 1 minute you divide 60 by 5, which would be 12 candy bars.

For 7 minutes you would add 60 and 24, which would be 84 candy bars.

Answer:

The correct answer is 28.

Step-by-step explanation:

Actually Jada makes problem simpler by adding and subtracting 1

that is

87 ₋ 59 ₋1 ₊ 1

so there would be no effect on our final answer because we have added 1 and also subtracted 1

Now,

87 - 59 -1 + 1

87 - 60 +1                ( ∵ -59 - 1 = -60 )

27 + 1                       (∵ 87 - 60 = 27 )

28

so the final answer is 28 .
