Answer:
-6
Step-by-step explanation:
Substitutet -7 for y in -3(9+y): -3(9 - 7) = -3(2) = -6
ANSWER: I’m pretty sure it’s D. 2x-9
EXPLANATION: factor out 3x from 6x2-27x=15 to get 3x(2x-9)=15. So, 2x-9 is one of the factors.
Answer:
The graph and the number line in the attached figure
Step-by-step explanation:
we have

Solve for x
subtract 7 both sides


Divide by -2 both sides
Remember
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so

The solution is the interval (-8,∞)
All real numbers greater than -8
In a number line the solution is the shaded area at right of x=-8 (open circle)
The graph and the number line in the attached figure
Cos y = 16 / 17.89 = 0.8944
y = cos^-1 (0.8944) = 26.57°
tan 26.57 = BA / 17.89
BA = 17.89 tan 26.57 = 8.95
tan x = 17.89 / 8.95 = 1.999
x = arctan 1.999 = 63.43
sin x = sin 63.43 = 0.8944
Answer:
Step-by-step explanation:
Given : Equation - 
To Find : All real solutions of the equation
Step1 - Write the equation :

Step 2 : To find the x-intercept we plot the graph,
when we plot the graph the points where y=0 are the x-intercept
Step 3: Points where y=0 are 5,2,1 (shown in the attached graph)
Therefore, (x-5)(x-2)(x-1) are the solutions of the equation.
Hence,
