9:10 bc you simplify, you have to find the GCF which is 7.

Answer:

9 : 10

Step-by-step explanation:

First the ratio will be 63 : 70

Now, we have to simplify! The GCF (greatest common factor) is 7, so let's divide both numbers by 7 to maintain equality.

63/7 = 9

70/7 = 10

9 : 10 is the final answer!

ASAP! GIVING BRAINLIEST! Please read the question THEN answer correctly! No guessing. Show your work or give an explaination.

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

Starting with the first part, shifting 2 units left, this means that for this new function, for each value of x, the original function is equal to if you plugged in a value 2 values higher. Therefore, we should be looking for a x+2 -- that's C. Then, for the second part, we need to go up 9 units, which adds 9, so C fits that as well.

Lorenzo rides his bike at a rate 5 yards per second. About how many miles per hour can Lorenzo ride his bike? ( HINT: 1 mike = 1

Karo-lina-s [1.5K]

About 10. He would go 5 yads per second × 60 to get 300 yards per minute. ×60 to get 18000 yard per hour. Than you divide 18000 by 1760 to get about 10

Which two numbers add up to -24 and multiple to -24

Aleks [24]

X + y = -24
xy = -24

$xy = -24$
$\frac{xy}{x} = \frac{-24}{x}$
$y = \frac{-24}{x}$

$x + y = -24$
$x + \frac{-24}{x} = -24$
$\frac{x^{2}}{x} + \frac{-24}{x} = -24$
$\frac{x^{2} - 24}{x} = -24$
$-24x = x^{2} - 24$
$0 = x^{2} + 24x - 24$
$x = \frac{-(24) \± \sqrt{(24)^{2} - 4(1)(-24)}}{2(1)}$
$x = \frac{-24 \± \sqrt{576 + 96}}{2}$
$x = \frac{-24 \± \sqrt{672}}{2}$
$x = \frac{-24 \± 4\sqrt{42}}{2}$
$x = -12 \± 2\sqrt{42}$
$x = -12 \± 2(6.5)$
$x = -12 \± 13$
$x = -12 + 13$ $or$ $x = -12 - 13$
$x = 1$ $or$ $x = -25$

  x + y = -24    or      x + y = -24
  1 + y = -24 or -25 + y = -24
- 1   - 1 + 25 + 25
y = -25     or    y = 1
  (x, y) = (1, -25) or (x, y) = (-25, 1)

The two numbers that add up to 24 are the numbers 1 and -25.

x + y = -24
xy = -24

$xy = -24$
$\frac{xy}{x} = \frac{-24}{x}$
$y = \frac{-24}{x}$

$x + y = -24$
$x + \frac{-24}{x} = -24$
$\frac{x^{2}}{x} + \frac{-24}{x} = -24$
$\frac{x^{2} - 24}{x} = -24$
$-24x = x^{2} - 24$
$0 = x^{2} + 24x - 24$
$x = \frac{-(24) \± \sqrt{(24)^{2} - 4(1)(-24)}}{2(1)}$
$x = \frac{-24 \± \sqrt{576 + 96}}{2}$
$x = \frac{-24 \± \sqrt{672}}{2}$
$x = \frac{-24 \± 4\sqrt{42}}{2}$
$x = -12 \± 2\sqrt{42}$
$x = -12 \± 2(6)$
$x = -12 \± 12$
$x = -12 + 12$ $or$ $x = -12 - 12$
$x = 0$ $or$ $x = -24$

  x + y = -24    or      x + y = -24
  0 + y = -24 or -24 + y = -24
- 0 - 0 + 24 + 24
y = 24    or    y = 0

The two numbers that multiply to -24 are the numbers 24 and 0.
