Answer:

x = -4, y = -3

Step-by-step explanation:

When you use graphing to solve a system of equations, the intersection point is the solution. Here, the coordinates of the intersection point or solution is: (-4, -3). Coordinates are mostly written like this: (x, y) Thus, the solution is:

(x, y)

(-4, -3)

x = -4

y = -3

What is the value of x for which m || n? x = 40 x = 5 x = 105 x = 30

QveST [7]

Answer:

(A) x=40

Step-by-step explanation:

Given: It is given that m is parallel to n.

To find: The value of x.

Proof: It is given that m is parallel to n, from the figure it can be seen that 105° and (3x-15)° forms alternate exterior angles which are equal in measure because m is parallel to n.

Thus, $105^{\circ}=3x-15^{\circ}$

⇒ $105^{\circ}+15^{\circ}=3x$

⇒ $120^{\circ}=3x$

⇒ $\frac{120}{3}=x$

⇒ $x=40$

Thus, the value of x is 40, hence option A is correct.

Can someone solve this with steps cause idk how to solve the radicals

IceJOKER [234]

$\bf 343^{\frac{2}{3}}+36^{\frac{1}{2}}-256^{\frac{3}{4}}\qquad \begin{cases}
343=7\cdot 7\cdot 7\\
\qquad 7^3\\
36=6\cdot 6\\
\qquad 6^2\\
256=4\cdot 4\cdot 4\cdot 4\\
\qquad 4^4
\end{cases}\\\\\\ (7^3)^{\frac{2}{3}}+(6^2)^{\frac{1}{2}}-(4^4)^{\frac{3}{4}}
\\\\\\
\sqrt[3]{(7^3)^2}+\sqrt[2]{(6^2)^1}-\sqrt[4]{(4^4)^3}\implies \sqrt[3]{(7^2)^3}+\sqrt[2]{(6^1)^2}-\sqrt[4]{(4^3)^4}
\\\\\\
7^2+6-4^3\implies 49+6-64\implies -9$

to see what you can take out of the radical, you can always do a quick "prime factoring" of the values, that way you can break it in factors to see who is what.

A hydraulic engineer is studying the pressure in a particular fluid. The pressure is equal to the atmospheric pressure 101 kN/m

miskamm [114]

Answer:

Step-by-step explanation:

The pressure is equal to the atmospheric pressure 101 kN/m plus 8 kN/m for every meter below the surface, therefore;

a. expression for pressure is given by,

$Pressure = 101 + 8d$ ............................... (1)

where d = depth below the surface in meter.

b. to find the depth at any pressure, equation (1) above is rearranged to make depth (d) subject of the formula

$d = \frac{Pressure - 101}{8}$

as an example, to find depth at pressure of 200N/m

d = (200 - 101)/8 = 12.375 meters

depth is 12.375 meters below the surface.
