Answer:

$5 \frac{13}{14}$

Step-by-step explanation:

$3 \frac{3}{7} + 2 \frac{1}{2}$

find LCM/ least common multiple

7:7 14 21 28 35...

2:2 4 6 8 10 12 14 16 18...

$3 \frac{3}{7} = 3 \frac{6}{14}$

$2 \frac{1}{2} = 2 \frac{7}{14}$

$3 \frac{6}{14} + 2 \frac{7}{14} =$

$5 \frac{13}{14}$

Answer:

Step-by-step explanation:

When you rearrange the equation, it would be y = 2x+1

If the y intercept is 1, and the slope is 2, then well c would uh work.

indicate in standard form the equation of the line in standard form. the line through (2,-1) and parallel to a line with slope 3

Art [367]

$k:y=m_1x+b_1;\ l:y=m_2x+b_2\\\\k\ \perp\ l\iff m_1\cdot m_2=-1\\\\k\ ||\ l\iff m_1=m_2$

We have $m_1=\dfrac{3}{4}$ .

$y=m_2x+b\to m_2=\dfrac{3}{4}$

$y=\dfrac{3}{4}x+b$

The line passes through point (2, -1). Substitute the coordinates of the point to the equation of a line:

$-1=\dfrac{3}{4}\cdot2+b\\\\-1=\dfrac{3}{2}+b\ \ \ \ |-\dfrac{3}{2}\\\\b=-\dfrac{2}{2}-\dfrac{3}{2}\\\\b=-\dfrac{5}{2}$

$y=\dfrac{3}{4}x-\dfrac{5}{2}\ \ \ \ |\cdot4\\\\4y=3x-5\cdot2\ \ \ \ |-3x\\\\-3x+4y=-10\ \ \ \ \ |\cdot(-1)\\\\3x-4y=10$

<h2>Answer: 3x - 4y = 10</h2>

Suppose f(x) = x2. What is the graph of g(x) = {f(x)?

sukhopar [10]

Answer:

f(x)=x2,g(x)=f(3x)=(3x)2=9x2

Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric around y axis. When x=1/3 or -1/3, then y=1.

Hope this helps! :))

The coordinate grid shows points A through K. What point is a solution to the system of inequalities? y ≤ −2x + 10 y > 1 over

vlabodo [156]

Answer:

A, C, D and K

Step-by-step explanation:

First, plot the solution set to the system of two inequalities.

The inequality $y\le -2x+10$ determines solid line and bottom shaded region under this line.

The inequality $y>\dfrac{1}{2}x-2$ determines dotted line and top shaded region under this line.

The intersection of these two regions is the solution set to the system of two inequalities.

Points A, C, D and K belong to this region.
