DedPeter [7]3 years ago
5 0

Answer:

For every 15 students scoring in the 60's there were 9 students scoring in the 70's.

Step-by-step explanation:

Your first step would be to rewrite the numbers into an easier to understand form like fractions, 45/3 and 27/3. Then you divide both numbers by 3, so you get comparable numbers. 45/3= 15, 27/3=9.

What is the equation of a line parallel to -x+3y=-6 that passes through 9,-1
Natali [406]

Answer:

{ \tt{ - x + 3y =  - 6}} \\ { \tt{3y = x - 6}} \\ { \tt{y =  \frac{1}{3}x - 2 }}

• For parallel line, their gradients are the same:

→ m = ⅓

• From general equation of a line;

→ \: { \tt{y = mx + c}} \\

• For the point (9, -1):

→ \: { \tt{ - 1 = (9 \times  \frac{1}{3} ) + c}} \\  \\→ \:  { \tt{ - 1 = 3 + c}} \\  \\ → \: { \tt{c =  - 4}}

therefore:

→ \: { \boxed{ \tt{y =  \frac{1}{3}x - 4 }}}

adell [148]

Answer:

  a(n) = 1/2(-8)^(n-1)

Step-by-step explanation:

The general term of a geometric sequence is ...

  a(n) = a(1)×r^(n-1)

where a(1) is the first term, and r is the common ratio.

Here, the first term is a(1) = 1/2. The common ratio is the ratio of any two sequential terms: r = 32/-4 = -8. Then the explicit formula is ...

  a(n) = 1/2(-8)^(n-1)
