Answer:

<h2>A, B, and D.</h2>

Step-by-step explanation:

According to the problem, the point (3, 6/5) represents a proportional relationship. To find the ratio of such proportion, we just need to divide the vertical coordinate by the horizontal coordinate as follows

r=\frac{y}{x}=\frac{\frac{6}{5} }{3}=\frac{6}{15}=0.4

The ratio of the proportion is 0.4. Now, we just need to find which point has the same ratio.

<h3>A.</h3>

r=\frac{0.4}{1}=0.4

This means that point A lies on the graph because it has the same ratio.

<h3>B.</h3>

r=\frac{\frac{6}{10} }{1.5}=\frac{0.6}{1.5}=0.4

Point B also lies on the graph.

<h3>C.</h3>

r=\frac{3}{\frac{6}{5} }=\frac{15}{6}=2.5

Point C doesn't lie on the graph because it doesn't have the same ratio.

<h3>D.</h3>

r=\frac{6}{15}=0.4

Point D lies in the graph.

Therefore, all points that also lie on the same graph are A, B and D, because all of them are in the same proportion.

Plz help me with the answer
UkoKoshka [18]

Answer:

<h2>y = 4</h2>

Step-by-step explanation:

Put x = 9 to the equation 3x + 4y = 43

(3)(9) + 4y = 43

27 + 4y = 43            <em>subtract 27 from both sides</em>

4y = 16            <em>divide both sides by 4</em>

y = 4

Find the area of the part of the plane 3x 2y z = 6 that lies in the first octant.
gavmur [86]

The area of the part of the plane 3x 2y z = 6 that lies in the first octant  is  mathematically given as

A=3 √(4) units ^2

<h3>What is the area of the part of the plane 3x 2y z = 6 that lies in the first octant.?</h3>

Generally, the equation for is  mathematically given as

The Figure is the x-y plane triangle formed by the shading. The formula for the surface area of a z=f(x, y) surface is as follows:

A=\iint_{R_{x y}} \sqrt{f_{x}^{2}+f_{y}^{2}+1} d x d y(1)

The partial derivatives of a function are f x and f y.

\begin{aligned}&Z=f(x)=6-3 x-2 y \\&=\frac{\partial f(x)}{\partial x}=-3 \\&=\frac{\partial f(y)}{\partial y}=-2\end{aligned}

When these numbers are plugged into equation (1) and the integrals are given bounds, we get:

&=\int_{0}^{2} \int_{0}^{3-\frac{3}{2} x} \sqrt{(-3)^{2}+(-2)^2+1dxdy} \\\\&=\int_{0}^{2} \int_{0}^{3-\frac{3}{2} x} \sqrt{14} d x d y \\\\&=\sqrt{14} \int_{0}^{2}[y]_{0}^{3-\frac{3}{2} x} d x d y \\\\&=\sqrt{14} \int_{0}^{2}\left[3-\frac{3}{2} x\right] d x \\\\

&=\sqrt{14}\left[3 x-\frac{3}{2} \cdot \frac{1}{2} \cdot x^{2}\right]_{0}^{2} \\\\&=\sqrt{14}\left[3-\frac{3}{2} \cdot \frac{1}{2} \cdot x^{2}\right]_{0}^{2} \\\\&=\sqrt{14}\left[3.2-\frac{3}{2} \cdot \frac{1}{2} \cdot 3^{2}\right] \\\\&=3 \sqrt{14} \text { units }{ }^{2}

In conclusion,  the area is

A=3 √4 units ^2

Solve and graph: 7x-6&gt;22<br>(pls explain your answer, im confused on this)​
grandymaker [24]

Answer:

x>4

Step-by-step explanation:

Solving an inequality is very similar to solving an equation:

Given: 7x-6>22

Add 6 to both sides: 7x>28

Divide both side by 7: x>4

x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.
