Answer:

y=2x+1

Step-by-step explanation:

Find the slope of the two points (2,5), (5,11). (11-5)/(5-2) = 6/3 = 2, m=2.

Use the point-slope formula to find the equation:

y-5=2(x-2)

y-5=2x-4

y=-2x-4+5

y=2x+1

Arisa [49]

Answer:

Step-by-step explanation:

g(x)=ax²+3x-5

then g(-1)=-15

therefore g(-1) ⇒ a(-1)²+3(-1)-5=-15

a-3-5=-15

a-8=-15

a=-15+8

a=-7

for g(-1)=-15

then g(x)= -7x²+3x-5

Morton made 36 out of 48 free throws last season. What percent of his free throws did Morton make. Help!!! T-T

blondinia [14]

75 % free throws are made by Morton

Solution:

Given that Morton made 36 out of 48 free throws last season

To find: Percent of free throws made by Morton

From given statement,

total number of throws = 48

throws made by morton = 36

Thus the percent of free throws made by Morton is given as:

$percent = \frac{\text{number of throws made}}{\text{total number of throws}} \times 100$

Substituting the values, we get

$percent = \frac{36}{48} \times 100\\\\percent = 0.75 \times 100 = 75 %$

Thus 75 % of his free throws are made by Morton
