Solve y=3bx-7x for x

1 answer:

6 0

Y = 3bx - 7x
y = x(3b - 7)

Divide each side by 3b - 7 (assume that it is not zero).
$\frac{y}{3b-7} =x$

Answer:
$x= \frac{y}{3b-7}$

Kyle says the number is greater when an object is measured in centimeters than in millimeters. Is Kyle correct? Explain

Lerok [7]

False.

1 centimeter = 10 millimeters.

with this knowledge, we can say, for example, that:

70 (in millimeters) as a number is greater than 7 (in centimeter), as 70 > 7

PLZ HELP, The sum of two numbers is 0.

notsponge [240]

Answer

y = -x

y = (3/2)x - 5

Explanation.
the sum of 2 numbers is 0
That will be,

x + y = 0

Adding x both sides we get,
y = -x

The other statements is,

3x - 2y = 10
Adding 2y on both sides we get,
3x = 10 + 2y

Subtracting 10 both sides we get,

2y = 3x - 10

Dividing both sides by 2 we get,

y = (3/2)x -5

An egg is dropped from the window of a building. The height, in feet, of the egg t seconds after it is thrown is represented by

joja [24]

Answer:

1.58

Step-by-step explanation:

Okay. We're solving for t because we need to know how many seconds. From the problem, we know the height (10), but we don't know when that height happens.

$10 = -16tx^{2} -7t+61$

We can factor by multiplying -16 by 61 first to get -976 and see what multiplies to get -976 AND adds to get -7 at the same time. But we can also use the quadratic formula because, let's be honest, factoring can be a lot of extra work.

$10 = -16t^{2} -7t+61\\\\0 = -16t^{2} -7t+51\\\\t=\frac{-b\pm \sqrt{b^{2}-4ac } }{2a} \\=\frac{-(-7)\pm \sqrt{(-7)^{2}-4(-16)(51) } }{2(-16)} \\=\frac{7\pm \sqrt{49+64(51) } }{-32} \\=\frac{7\pm \sqrt{3313} }{-32}$
