Step-by-step explanation:

If it took them 15 hours to go 735 miles, and you are trying to find the average rate, then divide the miles by the time (in hours), so for this specific problem, it would be 735 divided by 15 hours, and you will find the answer as 49. (MPH)

Please help me solve this short problem guys

-BARSIC- [3]

Answer:

Step-by-step explanation:

Given equation of the quadratic function is,

y = x² + 5x - 7

Convert this equation into vertex form,

y = x² + 2(2.5x) - 7

= x² + 2(2.5x) + (2.5)² - (2.5)² - 7

= (x + 2.5)²- 6.25 - 7

= (x + 2.5)² - 13.25

Therefore, vertex of the function is → (-2.5, -13.25)

For the solutions,

y = 0

(x + 2.5)² - 13.25 = 0

x = (±√13.25) - 2.5

x = (±3.64) - 2.5

x = 1.14, -6.14

Solutions → (-6.14, 0) and (1.14, 0)

What is 52/624 simplified?<br><br>(Hurry please)

ZanzabumX [31]

Hey there!

Simplifying fractions means dividing the numerator and the denominator by the same number.

So we know that both 52 and 624 are divisible by 2. However, it will take some time.

Turns out 624 is divisible by 52!

$\frac{1}{12}$ is the answer. Hope it helps!

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes. 2x+3y=6

sweet-ann [11.9K]

Answer:

x-intercept: (3, 0)

y-intercept: (0, 2)

Step-by-step explanation:

For a function like:

y = f(x)

The x-intercept is the value of x when y = 0

the y-intercept is the value of y when x = 0

Also remember that an ordered pair is written as (x, y).

In this case we have the equation:

2*x + 3*y = 6

For the x-intercept, we just replace y by zero in the equation, then we get:

2*x + 3*0 = 6

Solving this for x, we get:

2*x = 6

x = 6/2 = 3

Then in this case, the ordered pair for the x-intercept is (3, 0)

For the y-intercept, we just need to replace x by zero in the equation:

2*0 + 3*y = 6

Solving this for y, we get:

3*y = 6

y = 6/3 = 2

Then the ordered pair for the y-intercept is (0, 2)
