|x+1|>8 absolute value equations and inequalities

Mathematics
1 answer:
Pepsi [2]3 years ago
7 0

x < -9 or x > 7

x + 1 < -8

x < -9

x + 1 > 8

x > 7

... when the inequality sign is facing the x, x is GREATER and it resembles an OR statement.  I personally like to think of it as: greater than (greatOR than) = or statement; less than (less thAND) = and statement.

How do I make a formula for a line if they only give me the intercept and the slope
Eddi Din [679]
Well what you want is y = mx + b
m = slope
b = intercept for y
with that just substitute in the slope and the intercept, but leave the x and y as it is. So later on you can put in a x coordinate and get the y coordinate through that, hope this helps!

Solve for x: 4 over x equals 5 over 10
julsineya [31]

Answer:

x = 8,

Step-by-step explanation:

\displaystyle \frac{4}{x} = \frac{5}{10}.

x \ne 0 for it is a denominator. Multiply both sides with the product of the two denominators: 10\;x:

\displaystyle \frac{4}{x}\cdot (10\; x) = \frac{5}{10}\cdot (10\;x).

40 = 5\; x.

Multiply both sides by one over the coefficient of x:

\displaystyle \frac{1}{5} \times 40 = \frac{1}{5}\times 5\; x.

x = 8.

The path of a baseball after it has been hit is modeled by the function h = – 0.0032d2 + d + 3, where h is the height in feet of
aleksandr82 [10.1K]

Answer:

the maximum height of the ball is 81.125 feet above the ground. when the ball is at its peak, the ball is 156.25 feet away from home plate.

Step-by-step explanation:

x = d

y = h

to find the x coordinate of the vertex of a parabola, use the equation

x = -b/2a

y = ax^2 + bx+ c

y = – 0.0032x^2 + x + 3

x = -1 / 2 • - 0.0032

x = 156.25

plug x into original equation to find the the y coordinate of the vertex

y = – 0.0032 • (156.25)^2 + (156.25) + 3

y = – 0.0032 • 24414.0625 + 159.25

y = – 78.125 + 159.25

y = 81.125
