Hi!

<h3>To divide a fraction, you multiply by the reciprocal of the second fraction. </h3><h3>First, convert the mixed numbers to fractions, by multiplying the denominator by the whole number and adding that to the numerator. </h3>

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

2 * 7 = 14

14 + 1 = 15

15/7

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

4 * 1 = 4

4 + 1 = 5

5/4

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

<u> $\frac{15}{7} * \frac{4}{5} = \frac{60}{35} (simplify) = 1 \frac{5}{7}$ </u>

<h2>The answer is 1 5/7 </h2>

Hope this helps! :)

Write the standard form of an equation with p=3 sqrt2, theta= 135°

Arlecino [84]

Answer:

x - y + 6 = 0

Step-by-step explanation:

In normal form of a straight line, the equation is given by

$x\cos \theta + y\sin \theta = p$

where p is the perpendicular distance of the line from the origin and $\theta$ is the angle between the perpendicular line and the positive direction of the x-axis.

Here, in our case $p = 3\sqrt{2}$ and $\theta = 135$ Degree,

Therefore, the normal form of the straight line equation is

$x \cos 135 + y \sin 135 = 3\sqrt{2}$

⇒ $x \cos (180 - 45) + y \sin (180 - 45) = 3\sqrt{2}$

⇒ $- x \cos 45 + y \sin 45 = 3\sqrt{2}$ {Since, Cos (180 - Ф) = - Cos Ф and Sin (180 - Ф) = Sin Ф}

⇒ $- \frac{x}{\sqrt{2}} + \frac{y}{\sqrt{2}} = 3\sqrt{2}$

⇒ - x + y = 3√2 × √2 = 6

⇒ x - y + 6 = 0

So, the standard form of the equation is x - y + 6 = 0. (Answer)

What is the solution to this system of linear equations? 12q + 3r = 15 –4q – 4r = –44 (–18, 29) (–2, 13) (8, –1) (15, –44)

Akimi4 [234]

12q +3r =15
3(4q +r) = 3*5
Divide both sides by 3
4q +r = 5
Time for the second one:
-4q -4r = -44
-4(q +r) = (-4)*11
Divide both sides by -4
q +r = 11
4q +r = 5
q +r = 11
Subtract the second from first equation
3q 0 = -6
3q = -6
q = -6/3 = -2
q = -2
q +r = 11
-2 +r =11
r = 11 +2
r = 13
q = -2
r = 13
Your answer is...
(-2,13)

Find the distance between the points (6, 9) and (0, 1).

olganol [36]

Answer:

D= 10

Step-by-step explanation:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(0-6)^2+(1-9)^2}\\d=\sqrt{(-6)^2+(-8)^2}\\d=\sqrt{(36)+(64)}\\d=\sqrt{100}\\d=10$
