If x = 3 and y = 5, work out the value of a) 4x - 2y
b) 2x2 + 3y2
Answers
Answer:
A) 12-10
B)36+225
Step-by-step explanation:
A) 3x4=12, 5x2= 10= 12-10
B) 3x2=6x6=36, 3x5=15x15=225=36+225
For x = 3 and y = 5 the values of the given expressions are (a) 4x - 2y = 2 and (b) 2x² + 3y² = 93.
What is substitution?Substitution is a mathemaical technique for replacing variables with specific or covnient values according to the context.
When the values of variables are given to solve an equation we just have to replace those numerical values in place of the given variables.
Given, x = 3 and y = 5.
∴ 4x - 2y is,
= 4(3) - 2(5).
= 12 - 10.
= 2.
And
2x² + 3y².
= 2(3²) + 3(5²).
= 2(9) + 3(25).
= 18 + 75.
= 93.

Montana is known for having very chilly winters. One night, the temperature was falling by 2 degrees Fahrenheit each hour. At sunset, the temperature was -5 degrees Fahrenheit. How many hours will it take for the temperature to reach -19° F?
Answers
Answer:
7 hours
Step-by-step explanation:
We are given that
At sunset, the temperature=-5 degrees Fahrenheit
Each hour, temperature falling=2degrees Fahrenheit
We have to find time taken to reach the temperature -19° F.
Let x be the time time taken to reach the temperature -19° F
According to question
[tex]-5+x(-2)=-19[/tex]
Where we taking 2 negative because temperature decreases.
[tex]-5-2x=-19[/tex]
[tex]-5+19=2x[/tex]
[tex]14=2x[/tex]
[tex]x=\frac{14}{2}[/tex]
[tex]x=7[/tex]
Hence, it will take 7 hours for the temperature to reach -19° F.

Given a term in an arithmetic sequence and
the common difference find the 100th term.
a14= 102
d = 10
Please help, i’m struggling.
Answers
Answer:
100th term = 962
Step-by-step explanation:
You need to find the first term of the sequence
The formula to use is
[tex]a_{n} = a_{1} + (n - 1)d[/tex] In your problem, n = 14. So,
[tex]102 = a_{1} + (14 - 1)10\\102 = a_{1} + 130\\a_{1} = -28\\\\[/tex]
Now you can find the 100th term. n = 100, first term = -28 and d = 10
[tex]a_{100} = -28 + (100 - 1)10\\ = -28 + 990\\ = 962[/tex]
100th term = 962

A toy manufacturer is going to produce a toy that is a scale model of the giant robot in last summer's super hero movie, where 1 cm = 6 feet. If the robot in the movie was 36 feet tall, what will be the height of the toy?
Answers
Answer:
182.88 cm
Step-by-step explanation:
36/6 is 6 and 182.88 are in 6 feet
5.977cm will be the height of the toy when a toy manufacturer is going to produce a toy that is a scale model of the giant robot in last summer's super hero movie.
when 1 cm = 6 feet. If the robot in the movie was 36 feet tall, then we need to find the height of the toy.
What is 1 feet = ___cm?1 feet = 1/6cm=0.1666cm.
From given,
when 1 cm = 6 feet. If the robot in the movie was 36 feet tall, then we need to find the height of the toy.
then 1 feet = 1/6cm=0.1666cm
As 1 feet is 0.1666 cm , to find for 36 feet we need to multiply 1 feet value with 36.
If it is 36 feet =36*0.1666=5.977cm
Therefore 5.977cm will be the height of the toy.

To find the missing leg, we need to use a^2 + b^2 = c^2.
Let's call the missing leg a, and then substitute the numbers the other numbers
a^2 + 12^2 = 13^2
Simplify
a^2 + 144 = 169
To solve, subtract 144 from both sides (169-144)
a^2 = 25
This means that a squared is 25; to find a, we need to find the square root of 25.
a = 5
Your answer is 5.
Answer:
5m
Step-by-step explanation:
set it up
[tex]12^{2}[/tex]+[tex]a^{2}[/tex]=[tex]13^{2}[/tex]
do what you know
equation becomes: 144+[tex]a^{2}[/tex]=169
subtract both sides by 144
equation becomes [tex]a{2}[/tex]=25
square root both sides
equation becomes: a=5

Step-by-step explanation:
supplementary means that two or more angles add together to equal 180 degrees
a straight line equals 180 degrees so the intersecting of a line creates two angles that are supplementary. That means <5 is supplementary with 6 and 7.
<5=<1 because the lines intersecting it are parrell. Using the same thinking process for angle 1 as above, it is supplementary with 2 and 3. and since 1 is equal to 5 it is also supplementary to 2 and 3.
