Consider this system of equation. Which shows the second equation written in slope-intercept form?y = 3x - 210(x+3/5)=2yA) y=5x+
SashulF [63]

we have that

y = 3x - 2

10(x+3/5)=2y------> the second equation----->divide by 2 both sides

5(x+3/5)=y-----> y=5x+3

y=5x+3------> second equation written in slope-intercept form

so


case A) y=5x+3/10-----> is not equal to y=5x+3

case B) y=5x+3--->is equal to y=5x+3--------->  is the answer

case C) y=1/5x+3/25-------> is not equal to y=5x+3

case D) y=1/2x+6-----> is not equal to y=5x+3


therefore


the answer is the option

B) y=5x+3

Two numbers have difference of 0.7 and a sum of 1. What are the numbers?
algol [13]
We can solve this by setting up 2 equations. We can use any letters like. For now, I'll use x and y.
So now we know that    x - y = 0.7   and    x + y = 1.
Now we can eliminate one of the letters by adding or subtracting one equation from the other. I am going to eliminate y by adding the two together (the y and the -y cancel).
This gives us   2x = 1.7,    and so x = 1.7 ÷ 2 = 0.85
Finally, we can substitute x for 0.85 back into one of the original equations to figure out what y equals. I'm going to use   x + y = 1.
So now we have    0.85 + y = 1,    so y = 1 - 0.85 = 0.15

The numbers, therefore, are 0.85 and 0.15 (you can check by using the other equation).

Hope this helps!

If f left parenthesis x right parenthesis equals x squared minus 3 x plus 5 , then f left parenthesis 4 right parenthesis equals
lord [1]

Answer:

f(4) = 9

Step-by-step explanation:

f left parenthesis x right parenthesis equals x squared minus 3 x plus 5

f(x) = x² - 3x + 5

f left parenthesis 4 right parenthesis equals

f(4) =

f(x) = x² - 3x + 5

When x = 4

f(4) = 4² - 3(4) + 5

= 16 - 12 + 5

= 9

f(4) = 9
