Solve the system using substitution. Show all work. (3 points)<br> y=-2x+6<br> 3y-x+3=0
svp [43]
Y = -2x + 6....so we sub in -2x + 6 for y in the other equation

3y - x + 3 = 0
3(-2x + 6) - x + 3 = 0
-6x + 18 - x + 3 = 0
-7x + 21 = 0
-7x = -21
x = -21/-7
x = 3

now we sub 3 in for x in either of the original equations to find y.
y = -2x + 6
y = -2(3) + 6
y = -6 + 6
y = 0

so ur solution is : (3,0)

LUCKY_DIMON [66]

Step-by-step explanation:

We need to factorise 3x

2

−12xy

Here we can take 3x common.

Thus we have 3x

2

−12xy=3x(x−4y)

Hence, factors are 3x,(x−4y).

Women's heights are normally distributed with mean 63.5 in and standard deviation of 2.5 in. A social organization for tall peop
Vanyuwa [196]
First, ask yourself how far way is 70 from the mean of 63.5? It is equal to 70 - 63.5 = 6.5 inches. 

Next, ask yourself how many standard deviations is this? Well, every standard deviation equals 2.5 inches, so there are 6.5 / 2.5 = 2.6 standard deviations. So, 70 is exactly 2.6 standard deviations to the right of the mean. 

Finally, you can use the Standard Normal to find the answer P(X>70) since this is equivalent to: 

<span>P(z > 2.6) = 0.0054 or 0.54% of women will be taller than 70 inches. 

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
