3 × (c2 − 8) for c = 3
Answer:
I am assuming c2, is c^2.
3 × (c2 − 8)
=3 ×(3^2-8)
=27-8
=19
If c2 is c*2
Then,
3 × (c2 − 8)
=3×(6-8)
=18-24
=(-6)

y = -4x + 1
11y = x + 146
Step 2: Solve for x
Substitution
Substitute in y: 11(-4x + 1) = x + 146Distribute 11: -44x + 11 = x + 146[Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146[Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x[Division Property of Equality] Divide 45 on both sides: -3 = xRewrite/Rearrange: x = -3Step 3: Solve for y
Define original equation: y = -4x + 1Substitute in x: y = -4(-3) + 1Multiply: y = 12 + 1Add: y = 13please help i have to turn in in 8 mins....thanks :)

Step-by-step explanation:
6 is x. side across from right angle (12) is 2x. so 6x2 to get 12. missing side is x√3. so 6√3
Answer:
6√3
Step-by-step explanation:
using the pythagorean theorem you can plug in the numbers to get √(12^2 - 6^2) = √(144-36) = √108 = 6√3.

511 + 159 = 670
670 times 12 = 8040
negitive 17plus n over 5 =33 what is n
Answer:
250
Step-by-step explanation:
-17+n/5=33
n/5=33-(-17)
n/5=33+17
n/5=50
n=50*5
n=250
n=182
Step by Step Explanation:
The equation we would start out with is:
[tex] \frac{ - 17 + n}{5} = 33[/tex]
From here, we need to multiply both sides by 5. This would create an equation of -17+n=165, as we canceled out the 5.
Then, you need to add 17 to both sides to isolate the variable. This would make the equation n=182, our final answer.

Answer:
70% of people surveyed liked the plan.
Step-by-step explanation:
Given that,
No. of people that liked the plan = 2,800
No. of people that did not like the plan = 1,200
We need to find what percentage of the people surveyed liked the plan. It can be given by :
[tex]\%=\dfrac{2800}{2800+1200}\times 100\\\\=70\%[/tex]
So, 70% of people surveyed liked the plan.
The graph of y = f(x) is shown.
a) Find f(0)
4-
3.
b) Give the roots of f(x) = 0
Answer:
f(0) = 2
Roots are;
-2 and -1
Step-by-step explanation:
F(0) simply refers to the y-values when x = 0
This is the point at which the graph crosses the y-axis
the value here is 2
To
find the roots of f(x) , we simply find the points at which the plot crosses the x-axis
we have this at x = -2 and x = -1
These are what represents the roots of the equation
