[tex]5x + 7 = 3 + 4x \\ 5x - 4x = 3 - 7 \\ x = - 4[/tex]

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

From the question given :

General form of a slope intercept equation :

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

Answer:

37.5 units

Step-by-step explanation:

I assume that there is condition: BC║DE . If so, then ΔABC ~ ΔADE ⇒ that corresponding sides are proportional.

[tex]\frac{BC}{DE}[/tex] = [tex]\frac{AC}{AE}[/tex]

AC = 30 + 20 = 50

[tex]\frac{x}{15}[/tex] = [tex]\frac{50}{20}[/tex] ⇒ x = [tex]\frac{15*50}{20}[/tex] = 37.5 units

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

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:

Answer: -14 a^2 b - 42 a b^2 + 56 a b c

Step-by-step explanation:

A quadratic function,

f(x) = x²-4x-5 have 2 roots.

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

Given:

A quadratic function,

f(x) = x²-4x-5.

To find the roots:

f(x) = x²-5x+ x -5.

f(x) = (x - 5) (x+ 1)

The roots are x = 5 and -1.

Therefore, the roots are x = 5 and -1.

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
