Find the value of x

Answer:

y-25=180

Step-by-step explanation:

Same line so 180 degrees.

Answer: D or “y + 25 = 180”

a straight line is 180 degrees, therefore the combination of two angles should equal 180.

With that being said the answer should be y plus 25 = 180!

to find y, flip the equation: 180 - 25 = 155. Therefore y = 155 :)

Answer:

2y=4 is a linear function

Step-by-step explanation:

Since 2y=4 is the same as 2y¹=4, then a degree of 1 makes the function linear, aka. a straight line.

Answer:

Line 1: zero

Line 2: negative

Line 3: undefined

Line 4: positive

Step-by-step explanation:

Line 1 => slope is horizontal. The slope of horizontal lines are always equal to 0. Therefore, the slope of line 1 is zero.

Line 2 => the line slants downwards form our left to the right, this implies there is a decline or increase. Thus, the slope would be negative.

Line 3 => the line of a vertical line is always undefined. Line 3 slope is therefore undefined.

Line 4 => the slope slants upwards from our left to the right. This indicates a rising slope or an increase. Therefore, the slope of line 4 is positive.

Answer:  13kg potatoes=9.36    2.5 of carrots=155p

Step-by-step explanation:

potatoes 5kg=3.6  carrots .5kg=31p

value of each kg of potatoes is...

[tex]\frac{3.6}{5} =.72[/tex]  

so

[tex]13*.72=9.36[/tex]

value of each kg of carrots is...

31x2=62

so (I assumed when you typed 21/2 it meant 2 1/2 or 2.5)

2.5x62=155

The cost of 13 kg of potatoes is $ 9.36

The cost of  2 1/2 kg of carrots is $ 155p

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of 5 kg of potatoes be = $ 3.60

Let the cost of 1/2 kg of carrots be = 31p

Now , the equation is

The cost of 1 kg of potatoes = cost of 5 kg of potatoes / 5

                                               = 3.60 / 5

                                               = $ 0.72

So ,

The cost of 13 kg of potatoes is = 13 x cost of 1 kg of potatoes

                                                    = 13 x 0.72

                                                    = $ 9.36

Now , the equation is

The cost of 1 kg of carrots = cost of 1/2 kg of carrots x 2

                                            = 31 x 2

                                            = 62p

The cost of 2 1/2 kg of carrots is = 2 1/2 x cost of 1 kg of carrots

                                                      = 2 1/2 x 62

                                                      = 155p

Therefore , the cost of  13 kg of potatoes is $ 9.36 and cost of  2 1/2 kg of carrots is $ 155p

Hence ,

The cost of 13 kg of potatoes is $ 9.36

The cost of  2 1/2 kg of carrots is $ 155p

Answer:

[tex]\boxed {\boxed {\sf (4,3) \ is \ not \ a \ solution}}[/tex]

Step-by-step explanation:

If we want to test a solution, we can plug it into the equations and see if it checks out.

We are given the point (4,3). Since points are written (x,y)...

Substitute the values into the first equation.

[tex]11x+9y=17 \\11(4)+9(3)=17[/tex]

Multiply.

[tex]44+ 27=17\\[/tex]

Add.

[tex]71 \neq 71[/tex]

This does not check out, so we automatically know this point doesn't work. However, we can check the other equation.

[tex]x+y=7 \\4+3=7\\7=7[/tex]

Even though the second equation works, BOTH have to work because this is a system of equations. Therefore, (4,3) is not a solution.

D) $9150.73

Step-by-step explanation:

Simple compound irate =

principal*growth rate^years

or

V(t) = p*g^t

Where g = 100% + the given growth rate,

in this case, 5.2%

So,

V(8) = 6,100*1.052^8

V(8) = 9150.73

The term ( 7 - 4 ) is described as a difference or subtraction

An expression is combination of variables, numbers and operators.

The given expression is  5+3(7-4).

Two or more expressions with an Equal sign is called as Equation.

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 5 + 3 ( 7 - 4 )

And , ( 7 - 4 ) is described as a difference or subtraction between 7 and 4.

On simplifying , we get

A = 5 + 3 ( 3 )

A = 5 + 9

A = 14

Therefore , the value of A = 14

Hence , the term ( 7 - 4 ) is described as a difference or subtraction

Answer:

g(f(-1)) = 48

Step-by-step explanation:

given the following

f(x) = 5x² + 2

g(x) = x²-1

g(f(x)) = g(5x²+2)

Replace x with 5x² + 2 in g(x) as shown;

g(5x²+2) = (5x²+2))²- 1

g(f(x)) = (5x²+2))²- 1

g(f(-1)) = (5(-1)²+2))²- 1

g(f(-1)) = (5+2))²- 1

g(f(-1)) = (7)²- 1

g(f(-1)) = 49 - 1

Remark

I take it you are studying the sine law. If that is so, Then it will be set up as

Formula

x/sin(53) = 7 / sin(44)     Multiply both sides by Sin(53)

Solution

Sin(53)x/Sin(53) = 7 sin(53)/Sin(44)

x = 7*Sin(53)/Sin(44)

x = 7 * 0.7986/0.6947

x = 8.0848

Note:

The sine law is always set up by 2 ratios. It consists of the sine of an angle divided by the side opposite = equal to another angle's sine over the side oppose the second angle.

The sine law can also be set up as two ratios side opposite / sin(Angle).

Option D

Step-by-step explanation:

We have that:

csc(x) = 1/sin(x)

Then:

csc(  tan(√(17)/8)^-1 )

To use the inverse tangent function, you can go to the "inv" button in your calculator, and then use go to the "tan" button.

This is equal to:

= csc( 27.26°)

= csc(27.26°)

= 1/sin(27.26°) = 2.18

And we know that:

(9*√17)/17 = 9/√17 = 2.18

Then the correct option is D.
