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.

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

square root both sides

equation becomes: a=5

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.

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.

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.
