Answer:

9.6

Step-by-step explanation:

Step 1:

Find the rate of proportion

We can do 12/10 to find how many minutes it takes her to read 1 page, or 1.2.

Step 2:

Multiply 1.2 by 8 to get 9.6

ALTERNATIVE METHOD:

Divide 10 by 8 to get 1.25. Then divide 12 by 1.25 to get 9.6

Answer:

After 3 years, Sue will get £2471.70 and Bill will get £1993.28.

Step-by-step explanation:

Amount at Compound Interest, $A=P(1+\frac{r}{k} )^{nk}$

Since interest is compounded everyday, period, k=365.

Sue

Amount Invested, P=£2300

Interest Rate Per annum (Saver Account) = 2.4%=0.024

Period, k=365 days

Number of Years, n=3 years

$A=2300(1+\frac{0.024}{365} )^{365*3}\\=\£2471.70$

Bill

Amount Invested, P=£1800

Interest Rate Per annum (1234 Account ) = 3.4%=0.0034

Period, k=365 days

Number of Years, n=3 years

$A=1800(1+\frac{0.034}{365} )^{365*3}\\=\£1993.28$

After 3 years, Sue will get £2471.70 and Bill will get £1993.28.

Pls help! I'm confused. Can you explain this if you can.

Answer:

From a table, for an ordered pair (0, y), y will not be zero. From a graph, the y-intercept will not be zero. From an equation, it will have the form, y = mx + b where b is ≠ 0.

Step-by-step explanation:

From a table, for an ordered pair (0, y), y will not be zero. If there is not a constant rate of change in the data displayed in a table, then the table represents a nonlinear nonproportional relationship.
From a graph, the y-intercept will not be zero. This means that it doesn't contain or go through the origin.
From an equation, it will have the form, y = mx + b where b is ≠ 0. (not equal to zero). If an equation is not a linear equation, it represents a nonproportional relationship. A linear equation of the form y = mx + b may represent either a proportional (b = 0) or nonproportional (b ≠ 0) relationship. Therefore, when b ≠ 0, the relationship between x and y is nonproportional.

Answer:

Step-by-step explanation:

Given

f(x) = $\frac{x+3}{4}$

let f(x) = y and rearrange making x the subject

y = $\frac{x+3}{4}$ ( multiply both sides by 4 )

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

4y - 3 = x

Change y back into terms of x

$f^{-1}$ (x) = 4x - 3 → A
