Write an equation of a line that is parallel to y=-3x+5 that passes through the point (0,-4)

elena55 [62]

Answer:

${ \rm{y = - 3x + 5}}$

Gradient = -3

• Parallel lines have the same gradient, therefore gradient, m is -3

${ \rm{y = mx + c}}$

• At point (0, -4)

${ \rm{ - 4 = ( - 3 \times 0) + c}} \\ \\ { \rm{c = - 4}}$

y intercept is -4

${ \boxed{ \boxed{ \mathfrak{answer : }}{ \rm{\: \: y = - 3x - 4}}}}$

The common ratio in a geometric series is 4 and the first term is 3.

kodGreya [7K]

Answer:

The sum of the first 8 terms in the series is 65535.

Step-by-step explanation:

We have,

The common ratio in a geometric series, r = 4

First term of GP is, a = 3

It is required to find the sum of the first 8 terms in the series. The sum of first n terms of a GP is given by :

$S_n=\dfrac{a(r^n-1)}{r-1}, r>1$

Here, n = 8

$S_8=\dfrac{3\times ((4)^8-1)}{4-1}\\\\S_8=65535$

So, the sum of the first 8 terms in the series is 65535.

Could someone help me pls with this question it is math !

Nana76 [90]

Answer:

B) 275n + 1000 = 2700

Step-by-step explanation:

n is just a placer holder for how many days the Carter family can vacate.

That being said, the question says that they will spend 275 per day, which is per n. You want to multiply 275 by n.

Then the question says it plans to spend $1000 on meals (that's a lot). Instead of substracting, you are going to add for this equation. You want the equation to match; you want both sides to equal 2700 so you can determine how many days you can spend there.
