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
By using scientific notation we calculated (2.3
10⁵)(1.5
10⁴) we got 345
10⁷.
Given that,
(2.3
10⁵)(1.5
10⁴)
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
10⁵)=2.5
100000=230000
(1.5
10⁴)=1.5
10000=15000
Now,
=230000
15000
=3450000000
=345
10⁷
Therefore, By using scientific notation we calculated (2.3
10⁵)(1.5
10⁴) we got 345
10⁷.

Answer:
a) the largest y-intercept is 1
b) 13.5
c) y=x-3
d) 8
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
