Answer:
[tex]a_{n}[/tex] = (n + 1)²
Step-by-step explanation:
The terms are square numbers with each term shifted to the right by 1
That is 1, 4, 9, 16, 25, 36, .....
Thus to obtain 4 in the first position, then
n = 1 → (1 + 1)² = 2² = 4
To obtain any term add 1 to its position in the sequence, that is
[tex]a_{n}[/tex] = (n + 1)²
2x2 + 3x - 5 = (2x + 5)(?)
please help whats the missing numbers

What is 2 13/18 - z = 1 19/36
Answer z= 43/36
Step-by-step explanation:
We have given,
2 13/18 - z = 1 19/36
Since 2 13/18 = 49/18 and 1 19/36 = 55/36
So we can write,
2 13/18 - z = 1 19/36
or 49/18 - z = 55/36
or 49/18 - 55/36 = z
or (98 -55)/36 = z
or 43/36 = z
Hence we got z = 43/36
In triangle ACE, G is the centroid and BE = 18. Find BG and GE.
a BG=12, GE=6
b BG=4 1/2, GE=13 1/2
c BG=6, GE=12
d BG=9 GE=9
Answer: Choice C) BG = 6, GE = 12
=======================================================
Explanation:
The centroid G cuts the median segment BE such that BG is 1/3 of BE, and GE is 2/3 of BE.
So,
BG = (1/3)*BE = (1/3)*18 = 6
GE = (2/3)*BE = (2/3)*18 = 12
-------------
Put another way: GE is twice as long as BG
Let x = BG. This means 2x = GE
Leading to
BG+GE = BE
x+2x = 18
3x = 18
x = 18/3
x = 6 = BG
2x = 2*6 = 12 = GE

Step-by-step explanation:
One number is 3 more than 4 times the second number. Their sum is 43. Find the numbers. Answer : The numbers are , .
Step-by-step explanation:
Let x be the 2nd number.
Then the 1st number is 4x + 3.
We have 4x + 3 + x = 43, 5x = 40, x = 8.
Hence the numbers are 35 and 8.

Answer:
AC/GI = BC/HI
Step-by-step explanation:
To make use of the SAS similarity theorem, an angle must be shown congruent, and the sides on either side of it must be shown proportional. Here, the congruent angles are ...
∠C ≅ ∠I
and the proportional sides are ...
AC/GI = BC/HI . . . . . . matches the last choice
The function B gives the depth of the water, in inches, t minutes after Tyler began to fill the bathtub. What does B(9)=11 mean?
Answer:
B(9) = 11 means the depth of the water in the bathtub, 9 minutes after Tyler began to fill the bathtub is 11 inches
Step-by-step explanation:
Whereby the function is expressed as B(t) = d,
Where;
d = The depth of the water
Therefore, when we have B(9) = 11, by comparing with the general form of the function, B(t) = d, we have;
t = 9 = The time in minutes after Tyler began to fill the bathtub = 9 minutes
d = The depth of the water = 11 inches
Which gives the meaning of the equation, B(9) = 11 as the depth of the water in the bathtub, 9 minutes after Tyler began to fill the bathtub is 11 inches.

A 5 pound tub of cottage cheese at n dollars per pound costs $10.25 .
Write an equation for the following word problem
Answer:
5n = $10.25
Step-by-step explanation:
We know that the tub is 5 pounds, and costs $10.25. We also know that n is in dollars per pound. Dollars per pound can be written as the product of dollars, divided by pounds, so we can plug that in being n = $10.25/5, next we want to make the equation contain an integer on both sides and not contain any fractions, so we multiply both sides by 5, resulting in 5n = $10.25

Meg and Tanner take a road trip together where they take turns driving. The ratio of the number of miles that Meg drives to the number of miles that Tanner drives is 4:3. If Meg drives 112 miles, what was the length of the trip?
Answer:
Step-by-step explanation:
[tex]\frac{Meg}{Tanner}[/tex] = [tex]\frac{4}{3}[/tex]
total dist. driven = dist. Meg drove + dist. Tanner drove
Meg = 112
Tanner = x or how far did Tanner drive?
[tex]\frac{112}{x}[/tex] = [tex]\frac{4}{3}[/tex]
[tex]\frac{3}{4}[/tex] * 112 = x
84 =x so Tanner drove 84 miles
total driven = 112 + 84
total driven = 196 :)

Answer: x = 5
Step-by-step explanation:
Solve the system by substitution.
x + 6y = -2
-x= 3y - 10
Answer:
x = 22, y = -4
Step-by-step explanation:
x + 6y = -2 --- Equation 1
-x = 3y - 10 --- Equation 2
Equation 2 ×(-1): x = -3y + 10 --- Equation 3
Substitute x = -3y + 10 into Equation 1:
x + 6y = -2
-3y + 10 + 6y = -2
3y + 10 = -2
3y = -2-10
= -12
y = -12 ÷ 3
y = -4
Substitute y = -4 into Equation 3:
x = -3y + 10
x = -3(-4) + 10
= 12 + 10
x = 22

Answer:
[tex]y=-\frac{4}{7} x+\frac{55}{7}[/tex]
Step-by-step explanation:
Change the given equation to slope-intercept to get [tex]y=\frac{7}{4}x-\frac{1}{4}[/tex]. When you multiply the slopes of perpendicular lines, you get -1. -1 divided by [tex]\frac{7}{4}[/tex] is [tex]-\frac{4}{7}[/tex]. The slope of the new line is then [tex]-\frac{4}{7}[/tex]. The perpendicular line passes through (5, 5) so you can have the equation[tex]5=-\frac{4}{7} (5)+b[/tex]. Simplifying gets [tex]b = \frac{55}{7}[/tex] . So now the final equation for the perpendicular line is [tex]y=-\frac{4}{7} x+\frac{55}{7}[/tex]
