Answer:
Step-by-step explanation:
Let's solve for g.
gx=(−14(x−21))(2)+47
Step 1: Divide both sides by x.
gx
x
=
−28x+635
x
g=
−28x+635
x
Answer:
g=
−28x+635
x
Answer:
230-300= -70
All you have to do is subtract :)
1.86 is the answer of 7/10 divided by 3/8
Answer:
Option (C).
Step-by-step explanation:
Table represents the population of the owls in a park in different years and the quadratic regression equation that models the data of the table is,
y = -1.34x² + 10.75x - 11.3
Where y = number of owls
x = year
y = -1.34(9)² + 10.75(9) - 11.3
= -108.54 + 96.75 - 11.3
= -23.09
≈ -23
But Number of owls can't be negative.
Therefore, Option C. will be the answer.
You need to know the rule or theorem for the lengths of the sides of a triangle,which is: the lengths of any two sides of a triangle must add up to more than the length of the third side.
So, let's examine each option:
<span>A.4 inches => side A: 7, side B: 11, side C: 4 ---> NOT POSSIBLE
Justification:
7 + 4 = 11
11 = 11 => the sum of sides A and C is not greter than the side B, so it does not satisfy the rule.
B. 7 inches => side A: 7, side B: 11, side C: 7. ---> COULD BE
Justification:
7 + 7 = 14; 14 > 11
7 + 11 = 18; 18 > 7
C. 13.5 inches => side A: 7, side B: 11, side C: 13.5: ---> COULD BE
Justification:
7 + 11 = 18; 18 > 13.5
7 + 13.5 = 20.5; 20.5 > 11
11+13.5 = 24.5; 24.5 > 7
D. 18 inches => side A: 7, side B: 11, side C: 18 ---> NOT POSSIBLE
Justification:
7 + 11 = 18; 18 = 18 => it does not satisfy the rule.
E. 20 inches
=> side A: 7, side B: 11, side C: 20 ---> NOT POSSIBLE
Justification:
7 + 11 = 18; 18 < 20 => it does not satisfy the rule</span>
