ASAP!!!!!!!!!!!!!!!!!! Consider the point A=(1,3) and the line B, given by the equation y=2x-2 write an equation in slope-interc

Answer:

y = 2x+1 (slope-intercept form)

Step-by-step explanation:

From line B, y = 2x -2 and comparing with the general equation of line, y = mx +c, we have

m1 = 2

Parallelism rule states that m1=m2

Therefore, m2 = 2

Hence, the equation passing through point A(1,3) is

y-y1 = m2(x-X1)

y - 3 = 2(x-1)

y-3 = 2x-2

y = 2x-2+3

y = 2x+1 (slope-intercept form)

Math pls I need help
diamong [38]

Answer:

24

Step-by-step explanation:

First of all to check whether a number is divisible by 3 or not. We have to add the numbers and if the result is divisible by 3. Our number is divisible by 3 (no doubt). So 72 (7+2=9 is divisible by 3) ÷3 = 24

John took all his money from his savings account. He spent ​$110 on a radio and 4/11 of what was left on presents for his friend
svp [43]

Answer:

$1210

Step-by-step explanation:

Let x be total amount

First John spent $110 on a radio and 4/11 of what was left on presents for his friends so he was left with

\frac{7}{11}(x-110)=\frac{7}{11}x-70

Then he put 2/5 of his remaining money into a checking account

\frac{3}{5}\left(\frac{7}{11}x-70\right)

Rest he donated to charity

420=\frac{3}{5}\left(\frac{7}{11}x-70\right)\\\Rightarrow \left(\frac{7}{11}x-70\right)=\frac{2100}{3}\\\Rightarrow \frac{7}{11}x-70=700\\\Rightarrow \frac{7}{11}x=770\\\Rightarrow x=1210

Hence total amount of money John originally had was $1210

What is the equation of a line with a slope of -1/2 and passes through the point (6,-6)
Vlad [161]
Well I am going to assume you need slope-intercept form. So the equation is y=mx+b. m is slope, b is y intercept. So you just plug it in -6= -1/2(6)+b. -6=-3+b. Now you figure out for b so what does b have to be to make the equation equal. Well -3 so -6=-3+-3, or -6=-6. 

y=-1/2x-3
 
Hope that helped
