1) Inequality
2) Equation
Step-by-step explanation:
We need to identify the correct description
1) 7x+9<25
The sign < is called greater than and is an inequality symbol
So, the given term is an Inequality
2) 2x-3=5x+12
This is an equation because we equal (=) sign in it.
Solving the equation we can find value of x.
So, the given term is an Equation

Step-by-step explanation:
the relationship between x and y is defined by a constant factor.
you can "go" from x to y and from y to x consistently and without any interruptions by applying that constant factor.
that makes it a linear relationship (a line on a chart, hence the name).
proportional relationships are relationships between two variables where their ratios are equivalent. another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
so, yes, it is proportional.
and the table is then
x y
0 0
3 3×2/3 = 2
6 6×2/3 = 4
9 9×2/3 = 6
Answer:
y = -2x - 9
Step-by-step explanation:
so we have our two points, (-4,-1) and (-8,7) What we need to do to find our slope is y2 - y1 over x2 - x1. Once plugging in the numbers and subtracting it should give you 8/-4. 8 divided by -4 is -2. m = -2. Now to find our "b" we plug in our slope, and plug in one of the two points into the format of y = mx + b.
-1 = -2(-4) + b
multiply -2 and -4
-1 = 8 + b
we subtract 8 from itself and -1
-9 = b
Our equation is y = -2x - 9
Answer:
oof why tho :)

?????????????????
so 15% off is 149.85 which makes it 849.85 then you add sales tax which is 79.92 and your cost is 929.07
