List the coefficients from the following expression
3x + 6 - 8x + 1
Answer:
3 and 8
Step-by-step explanation:
Coefficients are just the numbers that accompany the variables. So if you have any number, let's take 4, and put it next to an x: 4x, 4 will be your coefficient.
1 .50+35=5(_____+7). 2._______+39=3(3+13) choices for number 2 16,1,5,9 . choices for number 1. 5,10,2,4
Answer:
1) 10
2) 9
Step-by-step explanation:
50+35=5(10+7) because 5*10=50 and 5*7= 35
9+39=3(3+13) because 3*3=9 and 3*13=39
The manager of a grocery store determined that the number of bananas remaining on the shelves at her store can be determined by the function b(n) = 150 − 6 n, where n is the number of hours since the store opened. According to this function, how many bananas are left on the shelves after the store has been open for 6 hours?

Which is the solution to the following system x+2y+z=9
X-y+3z=13
2z=10
Step-by-step explanation:
I'm not sure but,here you go
2z = 10
z = 10 ÷ 2 = 5
x + 2y + z = 9
x + y + 3z = 13
____________
x + 2y + 5 = 9
x + y + 3(5) = 13
_____________
x + 2y = 9 - 5
x + y = 13 - 15
___________
x + 2y = 4
x + y = -2 (×-1)
___________
x + 2y = 4
-x - y = 2
___________
y = 6
x = -2y - z + 9 = -2(6) - 5 + 9 = -12 - 5 + 9 = -8
If you wanna check,
x + y +3z = 13
(-8) + 6 + 3(5) = 13
x = -8 , y = 6 , z = 5
I'm not very sure but here you go,I might be wrong^^

The graph that is made up of two straight lines, which has an absolute maximum or absolute minimum, and is symmetric belongs to the
function family.
Answer:
This may be a function of the absolte value family.
f(x) = IxI.
f(x) = x if x ≥ 0
f(x) = -x if x ≤ 0
Where this is the parent function, and the graph is shown below in green.
If the coefficient is positive, then the lines open upwards, and we will have a minimum (in this case, when x = 0).
And also in this case, we have symmetry around the value x = 0.
Now, the vertex can also be an absolute maximum if the coefficient is negative, like in the example shown below in color blue (the equation for the blue graph is f(x) = -3*IxI )

Find the Value
A.
B.
C.
D.
Answer:
C
Step-by-step explanation:
Using the trig. identity
sin²x + cos²x = 1 ⇒ cosx = ± [tex]\sqrt{1-sin^2x}[/tex]
Here sinθ = [tex]\frac{1}{2}[/tex] , thus
cosθ = ± [tex]\sqrt{1-(\frac{1}{2})^2 }[/tex] = ± [tex]\sqrt{1-\frac{1}{4} }[/tex] = ± [tex]\sqrt{\frac{3}{4} }[/tex] = ± [tex]\frac{\sqrt{3} }{2}[/tex]
Since 0 ≤ θ > 90 then cosθ > 0 , thus
cosθ = [tex]\frac{\sqrt{3} }{2}[/tex] → C

The equation of the graph line is 2X-3Y=12
What is the x-intercept of the graph?
A. -4
B. -3/2
C.2/3
D.6
Answer:
A. -4
Step-by-step explanation:
For solving for x intercepts analytically. You can set the the y in the equation to 0. So, 2x-3(0)=12, and solving for x will get you -4.
You can also solve graphically by plugging in the equation and looking at where it intercepts the x axis.
Solve the two steps equations below and check your solution R/2-8=16
Answer:
r= 48
Step-by-step explanation
r/2 - 8 = 16
+8 +8
r/2 = 24
multiply both sides by two so it cancels out and you get r by itself.
the 2 cancels out and 24 times 2 = 48
r= 48
