Answer:

50 and 28

Step-by-step explanation:

x+y=78

x-y=22

to find this, subtract 22 from 78 to get 56

divide 56 by 2 to get 28

y=28

add 22 to 28 to get 50

x=50

to double check add 50 and 28 to get 78

also subtract 28 from 50 to get 22

Graph the linear equation using the slope and​ y-intercept.<br> Y=4X+3
JulsSmile [24]

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have y = 4x + 3

m = 4 - slope

3 - y-intercept


m=\dfrac{\Delta Y}{\Delta x}\to4=\dfrac{4}{1}

4 units up and 1 unit right

If anyone can give me the answer that will be greatly appreciated :)

42-x=58

or, -x=58-42

with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.

or, -x= 16

or,x=-16.

therefore x=-16...

Plzz Help ASAP!! i posted the picture?

Hi!


So the original formula for a problem likes this or a quadratic is:


ax^2 + bx+ c


so a is the accelaration; b is the initial velocity; and c is the initial height


so none of those are the zeros, which means c is out


zeros are the x values when y is 0, that also means when the parabola crosses the x axis


so d is out too because the maximum height is the vertex which mean that there would probably be a y value. in some cases the vertex is the zero, but not here


B is out because x isn't time it is distance

your answer is A!


Hope this helps!
