Factor this equation 75k^2+30k=-3

Solnce55 [7]

Answer:

k=-1/5

Step-by-step explanation:

Factor and set each factor equal to zero.

Add 3 to both sides of the equation.

75k^2+30k+3=0

Factor 3 out of 75k^2+30k+3.

Factor using the perfect square rule.

Divide each term by 3 and simplify.

Set the 5k+1 equal to 0.

Solve for k.

13 is the same as 1÷3. What is the exact quotient in decimal form of 1÷3?

Yuliya22 [10]

Answer:

Exact quotient is 0

Step-by-step explanation:

Given : $\frac{1}{3}$ is the same as 1÷3.

To find : What is the exact quotient in decimal form of 1÷3

Solution : Here the divisor is 3

dividend is 1

To find quotient we divide divisor by dividend

1÷3 or $\frac{1}{3}$ = 0.333...

So, the quotient is 0.333... and remainder goes on to 1 till the division goes on.

Exact quotient in decimal form is 0

Answer:

$\large\boxed{Q1.\ \text{2 times greater}}\\\\\boxed{Q2.\ J. 3}\\\\\boxed{Q3.\ B. -\dfrac{4}{5}}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Q1.

We have the equation of a line p in the standard form

$4x-3y=7$

Convert to the slope-intercept form:

$4x-3y=7$ subtract 3x from both sides

$-3y=-4x+7$ divide both sides by (-3)

$y=\dfrac{4}{3}x-\dfrac{7}{3}$

The slope $m_1=\dfrac{4}{3}$

From the table we have the points (4, 3) and (7, 5). Calculate the slope of line q:

$m_2=\dfrac{5-3}{7-4}=\dfrac{2}{3}$

Divide the slope of p by the slope of q:

$\dfrac{4}{3}:\dfrac{2}{3}=\dfrac{4}{3}\cdot\dfrac{3}{2}=2$

Q2.

Parallel line have the same slope. Therefore, if we have the equation of the line in the slope-intercept form, then we have the slope:

$y=3x+2\to m=3$

Q3.

Parallel line have the same slope.

Calculate the slope from given points (-11, 5) and (-6, 1):

$y=\dfrac{1-5}{-6-(-11)}=\dfrac{-4}{-6+11}=\dfrac{-4}{5}=-\dfrac{4}{5}$
