3 0

Answer:

<u><em>Decimal</em></u><u><em>:</em></u>

h = 4.2 ft

<em><u>Fraction</u></em><em><u>:</u></em>

h=4\frac{1}{5} ft

Step-by-step explanation:

\frac{9}{15} :\frac{h}{7}

<u><em>Cross multiply.</em></u>

h · 15 = 9 · 7

<u><em>Simplify.</em></u>

15h = 63

<u><em>Divide each side by 15.</em></u>

15h ÷ 15 = 63 ÷ 15

<em><u>Simplify.</u></em>

h = 4.2

What is 6x – 8 = 4 written as a system? y = 6x – 8 y = –4 y = 6x – 8 y = 4 y = –6x + 8 y = 4
mestny [16]

6x – 8 = 4 written as a system. Hence second option is correct

<u>Solution:</u>

Given, equation is 6x – 8 = 4.

We have to find the equivalent system from given options.

First let us solve given equation, 6x – 8 = 4 ⇒ 6x = 4 + 8 ⇒ 6x = 12 ⇒ x = 2

Now, let us solve one by one option ,so that when we get above solution, that is correct option.

  • y = 6x – 8 and y = -4 ⇒ put y = -4 in y = 6x – 8 ⇒ 6x – 8 = -4 ⇒ 6x = 8 – 4

⇒ 6x = 4 ⇒ x ≠ 2, wrong option

  • y = 6x – 8 and y = 4 ⇒ put y = 4 in y = 6x – 8 ⇒ 6x – 8 = 4 ⇒ 6x = 8 + 4 ⇒ 6x = 12 ⇒ x = 2, right option.
  • y = -6x + 8 and y = 4 ⇒ put y = 4 in y = -6x + 8 ⇒ -6x + 8 = 4 ⇒ 6x = 8 – 4 ⇒ 6x = 4 ⇒ x ≠ 2, wrong option

hence, second option is correct.

Which number is irrational?<br> -4<br> 2/9<br> 8.26<br> 11
kipiarov [429]

Answer:

None of them are irrational.

Step-by-step explanation:

An Irrational Number is a real number that cannot be written as a simple fraction.

Therefore:

-4 can be written as -4/1

2/9 is already in fraction

8.26 can be written as 826/100

11 can be written as 11/1

None of them are irrational.

However numbers like  \sqrt{x}, \pi are irrational as they can not be represented as fractions.

What happens to the graph of the line y = mx + b if the value of b is decreased?
ollegr [7]

Answer:

The lines moves lower.

Step-by-step explanation:

The steepness of a line is related to the slope, m.

b is the y-intercept, not the slope.

b is where the line intersects the y-axis.

Changing b changes the vertical position of the line.

Answer: The lines moves lower.
