Move 3 to the other side to isolate x.

-10 = 2x

Divide both sides by 2 to isolate x.

Find the gradient and y intercept of 3x+4y=5

noname [10]

Answer:

gradient = - $\frac{3}{4}$ , y- intercept = $\frac{5}{4}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + 4y = 5 ( subtract 3x from both sides )

4y = - 3x + 5 ( divide terms by 4 )

y = - $\frac{3}{4}$ x + $\frac{5}{4}$ ← in slope- intercept form

with slope m = - $\frac{3}{4}$ and y- intercept c = $\frac{5}{4}$

Please help solve this

Ne4ueva [31]

Answer:

last option

Step-by-step explanation:

We know that a₁ (or the first term) = 4 so we can rule out the second and third options. d (or the common difference) = 8 (because 4 + 8 = 12, 12 + 8 = 20 and so on) so our answer is the last option.

A credit card contains 16 digits between 0 and 9. However, only 100 million numbers are valid. If a number is entered randomly,

marusya05 [52]

Answer:

$P(valid) = 1 * 10^{-8}$

Step-by-step explanation:

Let us first find the number of possible credit card numbers that can be formed with the numbers 0 - 9.

We want to form a 16 digit number out of 10 digits, so, we have:

$N = 10^{16}$

There are $10^{16}$ numbers that can be formed.

There are only 100 million valid numbers ( $100 * 10^6 = 10^8$ ). Let the number of valid numbers be n.

Therefore, the probability of picking a number that is valid is:

P(valid) = n / N

$P(valid) = 10^{8} / 10^{16}\\\\P(valid) = 1 * 10^{-8}$

Factor the following , it is not prime

MrMuchimi

So 1/9-16z^2 this is a diffirence of two perfect squares thing
so (1/3)^2-(4z)^2
so ((1/3)-4z)((1/3)+4z)
