Answer:

The ordered pair to represent a in the equation a=2b+c if b=(6,3) and c=(-4,8) is: a=(8,14)

Step-by-step explanation:

b=(6,3)

c=(-4,8)

a=2b+c

Replacing b and c in the equation above:

a=2(6,3)+(-4,8)

Multiplying:

a=(2*6,2*3)+(-4,8)

a=(12,6)+(-4,8)

Adding:

a=(12+(-4),6+8)

a=(12-4,14)

a=(8,14)

3x - 7y = 11<br> What is y equal to?

lara31 [8.8K]

Answer:

3.666666667

Step-by-step explanation:

Simplifying

3x + -7y = 11

Solving

3x + -7y = 11

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

3x + -7y + 7y = 11 + 7y

Combine like terms: -7y + 7y = 0

3x + 0 = 11 + 7y

3x = 11 + 7y

Divide each side by '3'.

x = 3.666666667 + 2.333333333y

Answer:

I uploaded a file hosting link for your question.

See below for more details.

Step-by-step explanation:

$m=\frac{change(y)}{change(x)}$

$=\frac{10-2}{6-0}$

$=\frac{8}{6}$

$m=\frac{4}{3}$

10. How can you use similar triangles to solve real-world problems?

8090 [49]

Similar triangles can be extremely useful in architecture. For example, similar triangles can help represent doors and how far they swing. Also when using shadows that make the triangles you can use them to find the height of an actual object they can be used to construct many architectural designs and monuments for e.g, bridges. You can also determine values that you can’t directly measure. For e.g you. Can measure the length of your shadow and a tree’s shadow on a sunny day.

Nx-5= -0.4<br> What is N?

denis-greek [22]

Answer:

$\large\boxed{n=\dfrac{4.6}{x}}$

Step-by-step explanation:

$nx-5=-0.4\qquad\text{add 5 to both sides}\\\\nx-5+5=-0.4+5\\\\nx=4.6\qquad\text{divide both sides by}\ x\neq0\\\\\dfrac{nx}{x}=\dfrac{4.6}{x}\\\\n=\dfrac{4.6}{x}$
