7 + y = 5(2y – 1) + 3y

Answers

Answer:

y = 1

Step-by-step explanation:

Given

7 + y = 5(2y - 1) + 3y ← distribute and simplify right side

7 + y = 10y - 5 + 3y

7 + y = 13y - 5 ( subtract y from both sides )

7 = 12y - 5 ( add 5 to both sides )

12 = 12y ( divide both sides by 12 )

1 = y

what is the slope of a line whose equation is 2x-2y=20

Answers

Answer:

The slope is 1.

Step-by-step explanation:

To find the slope, we first have to turn this equation to the form y = mx + b.

2x - 2y = 20

Move 2x to the other side by subtracting it.

-2y = -2x + 29

Divide by -2 on both sides

y = x - 13

Answers

Answer:

-14 a^2 b - 42 a b^2 + 56 a b c C. is the answer

Step-by-step explanation:

Expand the following:

-14 a b (a + 3 b - 4 c)

Hint: | Distribute -14 a b over a + 3 b - 4 c.

-14 a b (a + 3 b - 4 c) = -14 a b a - 14 a b×3 b - 14 a b (-4 c):

-14 a b a - 14×3 a b b - 14 (-4) a b c

Hint: | Combine products of like terms.

-14 a b a = -14 a^2 b:

-14 a^2 b - 14×3 a b b - 14 (-4) a b c

Hint: | Combine products of like terms.

-14 a b×3 b = -14 a b^2×3:

-14 a^2 b + -14×3 a b^2 - 14 (-4) a b c

Hint: | Multiply -14 and 3 together.

-14×3 = -42:

-14 a^2 b + -42 a b^2 - 14 (-4) a b c

Hint: | Multiply -14 and -4 together.

-14 (-4) = 56:

Hours it takes Elena and Jada to meet: (2 points)

Answers

Answer:

The hours it takes Elena to meet Jada = 4 hours

Step-by-step explanation:

The distance between Elena and Jada = 32 miles

The speed with which Elena runs = 6 miles per hour

The speed with which Jada walks = 2 miles per hour

Let t, represent the time it takes until Elena and Jada meets, we have;

Distance = Speed × Time

The total distance covered by both Elena and Jada before they meet = The distance between them = 32 miles

The distance covered by Elena before meeting Jada = Elena's speed × The time that elapsed for them to meet

∴ The distance covered by Elena before meeting Jada = 6 mph × t

The distance covered by Jada before meeting Elena = Jada's speed × The time that elapsed for them to meet

∴ The distance covered by Jada before meeting Elena = 2 mph × t

The total distance covered by both Elena and Jada before they meet = The distance covered by Elena before meeting Jada + The distance covered by Jada before meeting Elena = 32 miles

∴ The total distance covered by both Elena and Jada before they meet = 6 mph × t + 2 mph × t = 32 miles

t × (6 mph + 2 mph) = 32 miles

t × 8 mph = t × 8 miles/hour = 32 miles

t = 32 miles/(8 miles/hour) = 4 hours

The time it takes until Elena and Jada meets = t = 4 hours

(-12,14) and (6,-1) write the linear equation in slope-intercept form that passes through the given points. PLEASE HELP ASAP THANK YOU!!!

Answers

The equation of the line written in slope intercept form is 0.8333x + 24

From the question given :

x1 = - 12 ; y1 = 14 ; x2 = 6 ; y2 = - 1

General form of a slope intercept equation :

y = bx + c

b = slope = (y2 - y1) / (x2 - x1)

Slope = (-1 - 14) / (6 - (-12)) = - 15 / 18 = 0.8333

The intercept, c can be obtained thus :

14 = 0.8333(-12) + c

14 = - 10 + c

14 + 10 = c

c = 24

Therefore, the equation can expressed thus y = 0.8333x + 24
