Solve the following system using the elimination method: 2a+2b=4 and 4a-3b=8

Lorico [155]

A = 2
b = 0

2a + 2b = 4 → 4a + 4b = 8

(4a + 4b = 8) - (4a - 3b = 8) → 7b = 0

b = 0

so a = 2

Write an equation of the line perpendicular to

AysviL [449]

Answer:

From general equation of a line:

$y = mx + b$

m » slope, b » y-intercept.

but perpendicularly:

$m _{1} \times m _{2} = - 1 \\ - 3 \times m = - 1 \\ m = \frac{1}{3}$

at point (6, 2):

$2 = ( \frac{1}{3} \times 6) + b \\ 2 = 2 + b \\ b = 0$

therefore, equation is :

${ \boxed{ \boxed{y = \frac{1}{3} x}}}$

Find the value of x. If necessary, round to the nearest tenth.

tankabanditka [31]

Answer:

B. 9.7 in.

Step-by-step explanation:

We have been given an image of a triangle. We are asked to find the value of x.

We will use area of triangle formula to solve our given problem.

$\text{Area of triangle}=\frac{1}{2}\times \text{Base*Height}$

$47\text{ in}^2=\frac{1}{2}\times x*x$

$2*47\text{ in}^2=\frac{1}{2}*2\times x^2$

$94\text{ in}^2=x^2$

Taking square root of both sides we will get,

$x=\sqrt{94\text{ in}^2}$

$x=9.6953597\text{ in}\approx 9.7\text{ in}$

Therefore, the value of x is 9.7 inches and option B is the correct choice.
