Answer:
68
Step-by-step explanation:
=> g²+13g
putting the value of g which is 4
=> 4²+13(4)
=> 16+52
=> 68
Answer:
68
Step-by-step explanation:
We simply just plug in 4 for g since the problem states that "g=4"
Which turns our expression to "[tex]4^{2} +13(4)[/tex]"
_________________________
We start by calculating what [tex]4^{2}[/tex] equals which is 16 (4 * 4)
Now we do 13 times 4 which is 52
52 + 16 = 68

Becky tells her friend about the Rule of 72 and her friend immediately
tries it out with her own example. Becky doesn't see all of her friend's
math but does see f(4) = 18 written on her friend's paper.
a. What do you know about the friend's investment based on this?
b. Is the friend's math correct based on the rule of 72?
Answer:
a. the investment earns 4%
b. yes
Step-by-step explanation:
The "rule of 72" says that an investment earning compound interest at x% will double in value after 72/x years. That is, ...
f(x) = 72/x
__
a.We interpret f(4) to mean Becky's friend is interested in the doubling time for an investment that earns 4% interest.
__
b.Using the above formula, ...
f(4) = 72/4 = 18
The friend's math is correct.
Is g = 4 a solution to the inequality below? 8 − g > 4
Answer:
Given, 3x−2<2x+1
⇒3x−2x<1+2
⇒x<3orx∈(−∞,3)
The lines y=3x−2 and y=2x+1 both will intersect at x=3
Clearly, the dark line shows the solution of 3x−2<2x+1.
Answer:
No
Step-by-step explanation:
If you input g = 4 into the inequality, you have
8 - 4 > 4
4 > 4
4 is NOT greater than 4
To be correct, the inequality would have to read:
8 - g ≥ 4
This would be correct because now it reads
4 ≥ 4
4 is greater than OR equal to four
The constant of proportionality from the table that follows is please help
Answer:
Nonexistent
Step-by-step explanation:
The constant of proportionality k is given by k=y/x
We have three examples:
1. x=-3, y=1 (k=-1/3)
2. x=-1, y=3 (k=-3/1)
3. x=3, y=-1 (k=-1/3)
Because the constants are inconsistent, the answer is the last option, Nonexistent.

The diagram shows three straight lines work out the size of angles a, b and c.
Answer:
a = 21°
b = 70°
c = 89°
Step-by-step explanation:
a = 21° as vertically opposite angles are equal
to work out b:
angles on a straight line add up to 180
b + 110 = 180
b = 180 - 110
b = 70°
to work out c:
the sum of angles in a triangle add up to 180
we have a and b
21 + 70 + c = 180
91 + c = 180
c = 180 - 91
c = 89°

James and Sarah went out to lunch. The price of lunch for both of them was $80. They tipped their server 20% of that amount. How much did each person pay if they shared the price of lunch and the tip equally? Each person paid $
Answer:
28 Dollars
Step-by-step explanation:
80 diveded by 2 is 40
20 percent of 40 is 8
there for each should have tipped 28
Answer:
total tipped = 20% × $80
= $16
total lunch price = $80 - $16
= $64
amount each person pay for tipped
= $16 ÷ 2
= $8
amount each person pay for lunch
= $64 ÷ 2
= $32
total each person pay for lunch and tipped
= $8 + $32
= $40

Answer:
4/15
Step-by-step explanation:
They have baked 1/3 + 2/5. To add you need common denominators.
1/3 = 5/15, 2/5 = 6/15
5/15 + 6/15 = 11/15. This is what they baked.
To find what is left, we need to subtract from 1. 1 = 15/15
15/15 - 11/15 = 4/15

Is (-5,2) a solution to this system of equations?
x=-5
y=2x+10
Answer: No, it's not the solution
Explanation:
Let's plug x = -5 into the second equation
y = 2x+10
y = 2(-5)+10
y = -10+10
y = 0
This shows that (-5,0) is the actual solution, instead of (-5,2)

Given: f(x) = 5x* - 3x² + 6x + 2. Find f(-2).
Answer:
f(-2) =-32
Step-by-step explanation:
f(x) = 5x* - 3x² + 6x + 2. f(-2)
f(-2) = 5(-2) - 3([tex]-2^{2}[/tex]) + 6(-2) + 2
f(-2) = -10 - 3(4) -12 + 2
f(-2) = -10 - 12 -12 + 2
f(-2) = (-10 - 12 -12) + 2
f(-2) = (-10 -24) + 2
f(-2) = (-34) + 2
f(-2) =-32
Hope that helps!
Answer:
[tex] \boxed{f( - 2) \: is \: - 32}[/tex]
Step-by-step explanation:
f(x) = 5x - 3x² + 6x + 2
f(-2) ?
substitute -2 as x into the equation of the function
f(-2) = 5(-2) - 3(-2)² + 6(-2) + 2
Note :positive × negative = negative(-x)² = -x × (-x)negative × negative = positive[tex]f( - 2) = - 10 - 3.4 + ( - 12) + 2[/tex]

What is the value of x ? ( x= ??)
A x = 121
B x = 10
C x - 59
D x = 20
Answer:
The variable x is equal to 10 degrees.
Step-by-step explanation:
A triangle's angles, in total, must equal 180 degrees.
71 + 50 + (6x-1) = 180
71 +50 = 121
121 + (6x-1) = 180
6x - 1 = 59
6x = 60
x = 10
At the first pep rally of the season, the football team and the volleyball team were presented to the student body. During the pep rally, up to 11 players talked to the crowd. Football players talked about 17 seconds each and volleyball players talked about 28 seconds each.
If the players only had a total of 242 seconds (4.03 minutes), which system of inequalities could be used to determine the number of football players (f) and volleyball player! (v) that could talk to the student body?
A. f+ y< 11 17f+ 287< 242
B. ftv< 11 17y + 28% < 242
C. f+ v< 11 176+ 28v< 242
D. ftv< 11 17v+28f< 242
Answer:
A. f + y ≤ 11
17f + 287 ≤ 242
Step-by-step explanation:
[] Let f be football players and v be volleyball players.
-> The total time must be less than or equal to 242 seconds.
-> If football players talked for 17 seconds, we can write it as 17f.
-> If volleyball players talked for 28 seconds, we can write it as 28v.
[] Coming back to the first point I made, the total time must be less than or equal to 242 seconds.
-> 17f + 28v ≤ 242
[] This is going to be a part of our system of inequalities
-> Because of this, we rule out the following options.
B & D - the football players talk for 17 seconds, not the volleyball players
C - not less than or equal too, only less than
[] This leaves us with the option of A.
-> The first part of it also works. If 11 players can talk to the crowd, then the total of f and v must be equal too or less than 11.
Have a nice day!
