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: 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: x equals 10x + 10

Step-by-step explanation:

√a is defined only when a >= 0.

Therefore for √4x * √(x + 2) to be defined, both 4x and x + 2 must be non-negative.

When 4x >= 0, x >= 0.

When x + 2 >= 0, x >= -2.

x >= 0 and x >= -2, therefore we have x >= 0. (D)

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 .

Answer:

14 months.

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.

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)

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:

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:

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
