airplane a traveled 1273 miles in four hours.For airplane b y=621 x/2 represents rate of speed over the same four hours wichair plane traveled at a faster rate and by what factor?round to the nearest hundredth

Answers

Answer: Airplane A by a scale factor of 1.02

Step-by-step explanation:

Airplane A: 1273/4=318.25

Airplane B: Rate is the slope of equation, 621/2=310.5

So,

318.25/310.5=1.0249

Airplane 'a' is faster than airplane 'b' by a factor of 1.03 times.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, An airplane 'a' traveled 1273 miles in four hours.

∴ The airplane 'a' traveled (1273/4) = 318.25 miles per hour.

For airplane b y = (621x)/2 + 0b represents the rate of speed over the same four hours

∴ The rate of change per hour for airplane 'b' is (621/2) = 310.5 miles.

So, airplane 'b' is faster than airplane 'a' by a factor of (318/25/310.5) = 1.0257 = 1.03 times.

Solve this equation

2 x + 3 = x - 4

Answers

Answer:

-7

Step-by-step explanation:

2x + 3 = x - 4

so you first add four to both sides of the equal sign:

2x + 3 = x - 4

+ 4 + 4

making the equation:

2x + 7 = x

you now subtract 2x from both sides:

2x + 7 = x

-2x - 2x

to get:

7 = -1x

you then divide both sides by -1:

7/-1 = -1x/-1

to get:

-7 equals x or x = -7

A fundraising organization will donate $250 plus half of the money it raises from a charity event.

What is the independent Variable?

What is the dependent Variable?

What is the domain?

What is the range?

Answers

Answer:

Independent Variable, Domain = Charity amount

Dependent Variable, Range = Donation amount

Step-by-step explanation:

Independent Variable is the causal variable. Dependent variable is the resultant or effected variable.

In this case, organisation donates money, a constant value (250) & a proportion (half) of charity. So, independent variable (causal) is charity, effecting the dependent variable ie donation.

Equation : Let donation = d, charity = c. Given : d = f (c) , where d = 250 + c/2

Domain is set of of all values for which a function is defined, range is the set of all values that f takes. So, domain is independent variable - charity & range is dependent variable - donation.

3/4 = 1/2y
y=

Answers

Answer:

y=1 1/2 (fraction)

y=1.5 (decimal)

Step-by-step explanation:

We want to get y alone, so we need to get rid of the 1/2 in front of it. To do that we can multiply each side by 2 since 1/2 + 1/2 = 1.

3/4= 1/2y

multiply each side by 2

To multiply 3/4 by 2 you need to multiply the numerators and then multiply the denominators

2•3=6 & 4 • 1 =4

6/4

simplify

y=1 1/2

(If you need it in decimal form it would be y=1.5)
