which one of these is. linear function

Answer: X=32

Step-by-step explanation: 85+63=148. The tree angles of a triangle equals 180 degrees, so 180-148=32

Step-by-step explanation:

let eqn be y = mx + b.

m = (-2 - 8)/(1 - 3) = 5

sub (3, 8):

8 = 5(3) + b

b = -7

therefore equation of the line is y = 5x - 7

Answer:

x = -14/3

Step-by-step explanation:

2 (4x-2) - 5x = -18

8x - 4 - 5x = -18

8x - 5x = -18 + 4

3x = -14

x = -14/3

Answer:

x=4 y=0

Step-by-step explanation:

3x+5y=12

-(x-3y=4)

3x+5y=12

3(-x+3y=-4)

3x+5y=12

-3x+9y=-12

14y=0

y=0

Then, substitute the y into the equation to find x

x-3(0)=4

x=4

Answer:

1 cupcake is made in 1.75 minutes.

1.75 minutes

Step-by-step explanation:

Divide 70 by 40 = 1.75.

49/28=1.75

The constant of proportionality of the given data is 0.57.

The constant of proportionality is the ratio of two proportional values at a constant value.

Now it is given that,

Time taken for icing 40 cupcakes = 70 minutes

∴ Icing of cupcakes in 1 minute = 40/70

                                                    = 0.57

Time taken for icing 28 cupcakes = 49 minutes

∴ Icing of cupcakes in 1 minute = 28/49

                                                    = 0.57

⇒ constant of proportionality = 0.57

Thus, the constant of proportionality of the given data is 0.57.

Answer:26.85 miles

Step-by-step explanation: 7.25+12.3+7.3=26.85

The factored form of the expression would be; (7x + 2√5) (7x - 2√5)

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to factor the expression form 49x² + 20

Therefore, 49 is a perfect square,

This expression could also be given as;

(7x)²- (2√5)²

Now, we know that:

a²- b² = (a + b) (a - b)

Now plug the values then we have:

(7x)²- (2√5)² = (7x + 2√5) (7x - 2√5)

Hence, the factored form of the expression would be; (7x + 2√5) (7x - 2√5)

The factored form of the expression 49x² + 20 will be (7x - 2i√5) and (7x + 2i√5). Then the correct option is B.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The expression is given below.

⇒ 49x² + 20

The expression can be written as,

⇒ 49x² - 20i²

Simplify the expression, then we have

⇒ 49x² - 20i²

⇒ (7x)² - (2i√5)²

⇒ (7x - 2i√5)(7x + 2i√5)

The factored form of the expression 49x² + 20 will be (7x - 2i√5) and (7x + 2i√5). Then the correct option is B.

Answer:

40.9 ft

Step-by-step explanation:

Perimeter is the sum of lengths of all outer sides of the shape. Since the rectangle has two pairs of parallel lines of the same length... It is safe to assume that the unmarked side length is 10 ft (just like it's parallel counterpart)

Now it is a simple matter of adding all of the outer sides.

8ft + 10 ft + 10 ft + 8.9 ft + 4 ft = 40.9 ft

Answer:

         See below :)

Step-by-step explanation:

The solution is, 12 multiple-choice questions are on the test.

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we have,

The right answer for the question that is being asked and shown above is that:

m + f = 15 ---> 3m + 3f = 45

3m + 5f = 51

now, we have.

3m + 3f = 45

3m + 5f = 51

-------------------

-2f = -6

f = 3

so, we get,

m + f = 15

m = 15 - 3

m = 12

So the correct answer is 12.

Hence, The solution is, 12 multiple-choice questions are on the test.
