3x+y=4 write the equation in slope intercept form​

Mathematics
1 answer:
LekaFEV [45]3 years ago
6 0

Answer:

y = -3x + 4

Step-by-step explanation:

sorry im late

but all you have to do is isolate the y

so to do that we have to get rid of the 3x

3x + y = 4

in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y

3x + y = 4

-3x          -3x

y = -3x + 4

and now y is isolated

fenix001 [56]
To find the difference, we need to subtract the height of the fish from the height of the bird. If we use sea level as 0, then the bird flies at 1,281 feet, and the fish swims at -282 feet.

1,281 - (-282) = <span>1,281 + 282 = 1,563 feet

There is a </span><span>1,563 feet difference between the height of the bird and the depth of the fish</span>

Borrow 1 from the whole number to rewrite 8 10/24.
koban [17]

Answer:

A. 7\frac{34}{24}

Step-by-step explanation:

We are given  the expression, 8\frac{10}{24}

On re-writing the expression after borrowing 1, we have,

8\frac{10}{24} = 7(\frac{10}{24}+1)

i.e. 8\frac{10}{24} = 7(\frac{10}{24}+\frac{24}{24})

i.e. 8\frac{10}{24} = 7\frac{34}{24}

Thus, the equivalent expression after borrowing 1 from the given expression is 7\frac{34}{24}.

Hence, option A is correct.

I'm confused- how do I form the equation with 2 pts?
klio [65]

Answer:

the equation of the line is   y = -3x - 6

Step-by-step explanation:

Note that since (0, -6) is the y-intercept, we can write the slope-intercept equation of the line as y = mx - 6.  The other given point is (-2, 0) (which happens to be the x-intercept also).  Starting with y = mx - 6, replace y with 0 and x with -2:  

0 = m(-2) - 6.  We now solve this for the slope, m:  0 = -2m - 6 becomes

2m = -6, or m = -3.

With m = -3 and b = -6, the equation of the line is   y = -3x - 6

Which equations results from adding the equations in this system?<br> x+6y=9<br> -x+2y=-15
UkoKoshka [18]

Answer:

8y = -6

Step-by-step explanation:

Simply add the equations as you would numbers.

The 'x's cancel each other out. The 'y's add together as normal numbers.

9 + (-15) = -6

Hope that this helps!
