which set of ordered pairs represents y as a function of x

Answer:

I believe it's answer A?

Answer:

64

Step-by-step explanation:

20% of 80=16

80-16=64

Answer:

Step-by-step explanation: Part 1= 0.2(2)+79=79.4

Answer:

-9

Step-by-step explanation:

5(-9-4)

5(-13)

-65

4(-9+15)

4(6)

24

-65<24 so -9 is false because -65 is not smaller than 24

The solution is Option A.

The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is given by

5 ( n − 4 ) < 4 ( n + 15 )

Now , on substituting the value of n as 80 in the inequality equation , we get

5 ( n − 4 ) < 4 ( n + 15 )

when n = 80

5 ( 80 - 4 ) < 4 ( 80 + 15 )

5 ( 76 ) < 4 ( 95 )

380 = 380

So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80

Hence ,

The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

Answer:

a = 8

Step-by-step explanation:

Write the equation:

7/a = 35/40

Divide:

7/a = 35/40

7/a = 35 ÷ 40

7/a = 0.875 (convert back to a fraction)

7/a = 7/8

Multiply:

8a • 7/a = 7/8 • 8a

8 • 7 = a • 7

56 = 7a

Divide to get answer:

56/7 = 7a/7

8 = a

a = 8

Answer:

Negative 7/40 or - 7/40

Step-by-step explanation:

Answer: -7/40

Step-by-step explanation:

first multiply the two negatives so it becomes (2-|-1/4+2 x 3/5|) /(-6)

then that becomes (2- | -1/4 + 6/5 | ) /(-6)
the sum of those two fractions become (2- | 19/20|) /(-6)

(2-19/20)/(-6)

2 - 19/20 /-6

21/20 /-6

multiple both by a negative so that become -21/20 /6

multiply the 6 with the recirocal so it becomes 1/6

-21/20 and 1/6 turn into -7/20 and 1/2 by canceling out with the greatest common factor of 3

now multiply both and u get -7/40

Answer:

Slope = (3/5)

Step-by-step explanation:

Point 1: (5, 3); Point 2: (10, 6)

            (x₁, y₁)               (x₂, y₂)

       y₂ - y₁        6 - 3           3

m = ----------- = ----------- = ---------

       x₂ - x₁        10 - 5          5

y - y₁ = m(x - x₁)

y - 3 = (3/5)(x - 5)

y - 3 = (3/5)x - 3

  +3               +3

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

y = (3/5)x

Answer:

x=11

y=4

Step-by-step explanation:

To solve for x, the polygon is symmetrical (because it is regular). So x-3 = 8

x= 11

Similar means the sides are proportional (will be in a ratio)

Big polygon ~ small polygon

16 ~4

8~y/2

We can use these to solve for y.

[tex]\frac{16}{4} =\frac{8}{y-2}[/tex]

Cross multiply: 16y-32 = 32
