2 The value of y is directly proportional
rusak2 [61]

Answer:

y = 17.5

Step-by-step explanation:

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition y = 35 when x = 140, then

35 = 140k ( divide both sides by 140 )

0.25 = k

y = 0.25x ← equation of proportion

When x = 70, then

y = 0.25 × 70 = 17.5

(2.3 x 105)(1.5 x 104) in scientific notation plssss ASAP
zhenek [66]

By using scientific notation we calculated (2.3\times10⁵)(1.5 \times10⁴) we got 345 \times10⁷.

Given that,

(2.3\times10⁵)(1.5 \times10⁴)

By using scientific notation

The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.

Now, we calculate

(2.3\times10⁵)=2.5\times100000=230000

(1.5 \times10⁴)=1.5\times10000=15000

Now,

=230000\times15000

=3450000000

=345 \times10⁷

Therefore, By using scientific notation we calculated (2.3\times10⁵)(1.5 \times10⁴) we got 345 \times10⁷.

Step-by-step explanation:

the question was worded very strangely and I will answer the way I precieved it.

for question d, I simply considered the question to be asking what is X when y is 17 and since the equation of that line is 2x-1
