What is 8 - 3x > -25 because i have been wondering all day

Svetllana [295]

Answer:

$8 - 3x > -25 : \left[\begin{array}{ccc}solution: x < 11\\Interval Notation:(-\infty,11)\end{array}\right]$

Step-by-step explanation:

$8-3x>-25$

Subtract $8$ from both sides:

$8-3x-8>-25-8$

Simplify:

$-3x>-33$

Multiply both sides by $-1$ (reverse the inequality):

$\left(-3x\right)\left(-1\right)$

Simplify:

$3x$

Divide both sides by $3$ :

$\frac{3x}{3}$

Simplify:

$x < 11$

Hope I helped. If so, may I get brainliest and a thanks?

Thank you, have a good day! =)

F(x) = -3 + 7 = 4
g(x) = -7 + 3 = -4

f(-3) - g(3) = 4 - (-4) = 4 + 4 = 8

Which ordered pair represents the y-intercept of the graph of the equation y = -3x - 9?

german

The y-intercept is the point where the graph crosses the y-axis. It is found by setting x=0. For your equation, that makes the x-term vanish and only the constant remains. The ordered pair is ...
(x, y) = (0, -9)

frez [133]

constraint 1
let
x = number of cups of chocolate
y = number of cups of vanilla
The equation that represents the total number of ice cream is:
x + y = 24
constraint 2
the ratio of the number of chocolate cups to vanilla cups is
y = (1/2) x
Using equations 1 and 2, you can find the number of cups of each favor required.
answer:
x + y = 24
y = (1/2) x
