Answer:
x = - 3
Step-by-step explanation:
Given
7(x + 2) = 2x - 1 ← distribute parenthesis on left side
7x + 14 = 2x - 1 ( subtract 2x from both sides )
5x + 14 = - 1 ( subtract 14 from both sides )
5x = - 15 ( divide both sides by 5 )
x = - 3
Answer:
1 and 2/5 yards wastes only 1/15 a yard
Step-by-step explanation:
1 and 1/6 yards would make a waste of 1 and 1/6 yards since you can't make a ribbon out of it. (incorrect)
1 and 2/10 yards would make a waste of 1 and 1/5 yards since you can't make a ribbon out of it. (incorrect)
1 and 2/5 yards
Wastes 1/15 a yard.
1 and 1/2 yards
It wastes 1/6 a yard.
2 yards
It wastes 4/6 a yard.
3x²-y³ - y³ - z if x = 3, y = -2, z = -5
Simply plug in all the values :)
3(3²) - (-2³) - (-2³) - (-5)
Simplify.
3(9) + 2³ + 2³ + 5
Simplify.
27 + 8 + 8 + 5
Simplify.
35 + 13
Simplify.

~Hope I helped!~
2x + 8 > 18 2x+ 8 ≥ 18
2x > 18 -8 2x ≥ 18 - 8
2x > 10 2x ≥ 10
x > 10/2 x ≥ 10/2
x>5 x ≥ 5
The answer that combines both inequality is x ≥ 5

Explanation:</h2>
Using graph tools we can graph the function:
which is the red graph shown below. As you can see, this is a parabola. The rule for vertical and horizontal shifts is as follows:
Therefore, If we shift the red graph 9 units to the right and 1 down, our new function (let's call it ) will be:
This graph is the blue graph below. Let's verify the transformation taking the vertex of the red graph:
By translating the 9 units to the right and 1 down the vertex is also translated by the same rule, so:
