Answer:

Part 1) The solution is the point (-2,0)

Part 2) The solutions are the points (-2,0) and (0,2)

Step-by-step explanation:

Part 1

we have

$y=x+2$ -----> equation A

$y=0.5(x+2)$ ----> $y=0.5x+1$ ---> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

using a graphing tool

The solution is the point (-2,0)

see the attached figure N 1

Part 2

we have

$y=x+2$ -----> equation A

$y=0.5(x+2)^2$ ----> equation B

Solve the system by graphing

Remember that the solution of the system are the intersection points both graphs

using a graphing tool

The solutions are the points (-2,0) and (0,2)

see the attached figure N 2

A triangle is given by A ( 3,2 ) B (-1,5) and C (0,-1) . What is the equation of the line through B parallel to AC ( give ans an

Leokris [45]

Answer:

Step-by-step explanation:

Solution :

hello :

note :

Use the point-slope formula.

y - y_1 = m(x - x_1) when : x_1= -1 y_1= 5

m= the slope is : (YC - YA)/(XC -XA)

(-1-2)/(0-3) = -3/-3 =1

( parallel to AC means same slope)

an equation in the point-slope form is : y -5 = 1(x+1)

y=x+6

(Can somebody find the sum of this) (5+2i)+(8-3i)

7nadin3 [17]

Hey there!!

Okay so here are the steps....

(5 + 2i) + (8 - 3i) <---- when we have exponents we should worry about the "i" because it is equal to √-1 but here it isn't the case.


(13 - i) <----- This is the answer!

I hope this helps! ^__^

I dont understand this at all. I really need help!

Hello!

$\large\boxed{x^{4}}$

Recall that:

$\sqrt[z]{x^{y} }$ is equal to $x^{\frac{y}{z} }$ . Therefore:

$\sqrt[3]{x^{2} } = x^{\frac{2}{3} }$

There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:

$(x^{\frac{2}{3} })^{6} = x^{\frac{2}{3}* 6 } = x^{\frac{12}{3} } = x^{4}$

Use distributive property to simplify. 10(-8s-k) just need to check if -80s-10k is correct.

Nitella [24]

10(-8s-k)
(10) (-8s + -k)
(10) (-8s) + (10) (-k)
= -80s - 10k
= -10k-80s
