Re-write the equation 3x - y = 4 in slope-intercept form.

Verdich [7]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Rearrange 3x - y = 4 into this form ( add y to both sides )

3x = y + 4 ( subtract 4 from both sides )

3x - 4 = y OR y = 3x - 4 → a

Can you help me please

45/45/90 triangles have side lengths leg/leg/leg root2
Here the leg is root 7 and the x is in the hypotenuse so x is root 7 * root 2
Simplifies to root 7*2 = root 14

The sum of digits in a two digit number formed by two digits from 1 to 9 is 8. If 9 is added to a number then both the digits be

Arturiano [62]

<h2>Explanation:</h2><h2></h2>

Here we need to set a system of two linear equations in two variables. So:

<em>The sum of digits in a two digit number formed by two digits from 1 to 9 is 8:</em>

Let $x \ and \ y$ be those digits, then:

$x+y=8 \ \ldots eq1$

<em>If 9 is added to a number then both the digits become equal. find the number:</em>

<em />

<em /> $10x+y+9 \ldots expression \ 1$ <em />

<em />

But from eq 1:

$y=8-x$

Substituting y into the expression 1:

$10x+(8-x)+9=9x+17$

The x-value will be found by hit and trial, so:

Let x = 1:

$9x + 17 = 9(1)+17 = 26$

We have to reject this solution because digits are different.

Let x = 2:

$9x + 17 = 9(2)+17 = 35$

We have to reject this solution because digits are different.

Let x = 3:

$9x + 17 = 9(3)+17 = 44$

<em>Then this is a two digit number formed by two equal digits. </em>

Finally, the number is:

Question 11 (Multiple Choice Worth 1 points

Diano4ka-milaya [45]

Answer:

$3\frac{4}{33}=3.\bar1\bar2$

Step-by-step explanation:

Given:

Simplify The given choice.

$3\frac{4}{33}=\frac{33\times 3 +4}{33}=\frac{99+4}{33}=\frac{103}{33}=3.1212121=3.\bar1\bar2$

$3\frac{8}{33}=\frac{33\times 3 +8}{33}=\frac{99+8}{33}=\frac{107}{33}=3.242424=3.\bar2\bar4$

$3\frac{10}{39}=\frac{39\times 3 +10}{39}=\frac{117+10}{39}=\frac{127}{39}=3.2564$

$3\frac{5}{39}=\frac{39\times 3 +5}{39}=\frac{117+5}{39}=\frac{122}{39}=3.12820$

Therefore, the first option $3\frac{4}{33}$ is correct.
