Tyler and Han is trying to solve this system by substitution:
x + 3y = -5
9x + 3y = 3
Tyler's first step is to isolate x in the first equation to get x = -5 - 3y. Hans first step is to isolate 3y in the first equation to get 3y = -5 - x show that both first steps can be used to solve the system and will yield the same solution.

PLZ HELP, GIVING BRAINLIEST!! A swimmer dives straight into the ocean. His depth, d, in meters after t seconds, can be modeled using the equation d = (t - 3)^2 - 16 What is the lowest depth the swimmer reaches? How long does it take the swimmer to reach the lowest depth? a. 9 feet, 16 seconds b. 16 feet, 3 seconds c. 3 feet, 16 seconds d. 16 feet, 9 seconds
The time taken by the swimmer to reach the lowest depth will be 9 seconds. The correct option is D.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a swimmer dives straight into the ocean. His depth, d, in meters after t seconds, can be modeled using the equation d = (t - 3)² - 16.
The time will be calculated as below;-
d = ( t - 3 )² - 16.
16 = ( t - 3 )² - 16
32 = ( t - 3 )²
√32 = t - 3
5.67 = t - 3
t = 5.67 + 3 = 8.67 ≅ 9 seconds
Therefore, the time taken by the swimmer to reach the lowest depth will be 9 seconds. The correct option is D.

Graph the given function. State the domain and range. y=-11√6-9x+1
Find the missing number so that the equation has infinitely many solutions. -4x+20=blank x+20
Answer:
0
Step-by-step explanation:
20 cancels itself out so
-4x = x
-4x - x = 0
-5x = 0
divide both sides by -5x
x= 0 but we don't write it out
For the equation -4x+20 to have infinite solution , it should be equal to

Write y = 3x - 5 in function notation
Answer:
f(x) = 3x -5
Step-by-step explanation:
The equation for a line is already a type of function, so you simply replace y for f(x), g(x), or something similar to that
The function notation of y = 3x - 5 is
f(x) = 3x - 5.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
y = 3x - 5
Put y = f(x)
Where x is the input and f(x) is the output.
Thus,
f(x) = 3x - 5 is our function.

2(4m + 1) = 4(3 + 2m) what os the value of m in the equation below?
Answer:
No solution.
Step-by-step explanation:
[tex]2(4m + 1) = 4(3 + 2m)\\[/tex]
Expand:
[tex]2\times4m+2\times1=4\times3+4\times2m[/tex]
[tex]8m+2=12+8m[/tex]
Subtract 2 from both sides:
[tex]8m+2-2=12+8m-2[/tex]
[tex]8m=8m+10[/tex]
Subtract 8m from both sides:
[tex]8m-8m=8m+10-8m[/tex]
[tex]0=10[/tex]
Since both sides are not equal, there is no solution, because the value of m will not affect this end result of [tex]0=10[/tex] which is false.
Answer:
any or all real number, meaning anything works, the equations are equal!
Step-by-step explanation:
2(4m + 1) = 4(3 + 2m)
8m+2=12+8m
8m=10+8m
0=10
this means that m can be any real number

Find the area.
A. 1818 sq cm
B. 1406 sq cm
C. 1246 sq cm
D. 141 sq cm
E. 146 sq cm
Answer:
C
Step-by-step explanation:
39*34= 1326 (the area of the full square
8*10=80 (the area of the small square that is cut off)
1326-80= 1246
Answer:
C = 1246 sq. cm.
Step-by-step explanation:
finding the area is simply splitting the area into two (see image)
A1 = 26 x 39 = 1014
A2 = 8 x 29 = 232
total area = 232 + 1014
total area = 1246 sq. cm.
therefore, the answer is C = 1246 sq. cm.

Answer:
Shelby. If Ryann's time was 18.3, not 183 seconds, then the second-place winner would be Ryann.
Step-by-step explanation:
Looking at the table, we see that Madison had the lowest time, (18 seconds) and Shelbie and Tammie follow her in that order (Shelbie came second and Tammie third.) Again, if Ryann's time was 18.3 and not 183 seconds, he would have won second place and Shelbie would have gotten third. Hope this helped!
