If 2a/4=b/4 and b≠0, what does 5b equal in terms of a?

Mathematics

dedylja [7]1 year ago

Step-by-step explanation:

you must have made a typo here.

none of the answer options are correct for the given problem.

let me just show you what you told me, and how I can solve at least this :

2a/4 = b/4

this simply means (multiply both sides by 4) :

2a = b

so, 5b is then (multiplying both sides by 5) :

5×2a = 5b

10a = 5b

but again, "10a" is not among the offered answers.

so, I don't know if you made a mistake with the basic problem or with the answer options.

What is the equation, in slope-intercept form, of the line that passes through (0, 3) and has a slope of −6?
crimeas [40]

Answer:

The answer is

<h2>y =  - 6x - 3</h2>

Step-by-step explanation:

To find the equation of the line given a point and slope we use the formula

<h3>y  - y_{1} = m(x - x _{1})</h3>

where

m is the slope

( x1 , y1) is the point

From the question the point is (0 , 3) and slope is - 6

Substitute the values into the above formula and solve

That's

<h3>y -  3 =  - 6(x - 0) \\ y - 3 =  - 6x</h3>

We have the final answer as

<h3>y =  - 6x - 3</h3>

Hope this helps you

A jeepney ride cost 11 pesos for the first 4 kilometers and each additional integer kilometers adds 3.50 pesos to the fare, use
Nookie1986 [14]

Answer:

f(d)=\left\{ \begin{matrix} 11 & \text{for} & 0< d\leq 4  \\-3+3.5d & \text{for}&  d > 4  \end

Step-by-step explanation:

Cost of first 4 kilometers ride = 11 pesos.

So, for the first 4 km, the fair is constant i.e.

for 1 km the fare is 11 pesos,

for 2 km the fair is also 11 pesos,

similarly, for 3 km of 4 km, the fare is 11 pesos.

Hence, for the distance 0\geq d\geq 4, the fair function,

f(d)=11\cdots(i)

After 4 km, there is an increment of $ 3.50 for each kilometer.

So, the fare function up to 5 kilometers,

f(d)=11+3.5=14.5

So, the fare function up to 6 kilometers, i.e for the distance 5,

f(d)=11+2\times3.5=18

This can be arranged as the fare function up to 6 km,

f(d)=11+(6-4)\times3.5=18

Similarly, the fare function up to d kilometer (n>4),

f(d)=11+(d-4)\times3.5

\Rightarrrow f(d)=-3+3.5d\cdots(ii)

Hence, from equations (i) and (ii),

f(d)=\left\{ \begin{matrix} 11 & \text{for}\; 0< d \leq 4  \\-3+3.5d & \text{for}\;  d > 4  \end
