the answer is 30 because if you count by 6 it would go 6,12,18,24,30,36,42 and if you go by 15 it would be 15,30,45,60,75,90..... and the only number that you see twice is 30 so the answer would be 30. Hope this helped...

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 = $\frac{5}{4}$
