Baxter, Jackie, Quincy, and Valerie open savings accounts. At the end of each month, all four friends deposit different amounts of money into their savings accounts.

of the four, which friend is saving money at a proportional rate?

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:

19

Step-by-step explanation:

If you're asking how many quarters in 4 3/4

In 1 there are 4 quarters so do 4 multiplied by the 4 quarters which is 16. In 3/4 we have 3 quarters so 16 add the 3 is 19.

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

Answer: 100°

Step-by-step explanation: LKO and GKO equal 180°. 180 (total of the supplementary angles) - 80° (LKO) = 100°

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

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

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
