If C = x2 + 8x + 3 and B = x – 8, find an expression that equals 3C + B in
standard form.
Answer: 3x^2 + 25x + 1
Step-by-step explanation:
3C + B
=> 3(x^2 + 8x + 3) + (x - 8)
=> 3x^2 + 24x + 9 + x - 8
=> 3x^2 + 25x + 1
Does the equation represent a linear or nonlinear function?
y=x2+3
Answer:
Nonlinear function.
Step-by-step explanation:
If the x2 is supposed to mean x², then the function is quadratic, not linear.
Answer: Nonlinear function.
Step-by-step explanation:
the variables do not have powers more than 1,
variables do not occur in the denominator of a fraction.
different variables do not appear in the same term
In this case, there is a term in x2
so the function is not linear.
It is a parabola.
Divide £180 in the ratio 3:7
Answer:3+7=10
180*3/10=54
180*7/10=126
126+54=180
54&126
Answer:
One = 3x = 3 x 18 = 54
Second = 7x = 7 x 18 = 126
Step-by-step explanation:
3x+7x = 180
10x = 180
x = 180/10 = 18
One = 3x = 3 x 18 = 54
Second = 7x = 7 x 18 = 126
I hope im right!

Solve for p.
8p-4p=2p+6
Answer:
p=3
Step-by-step explanation:
8p-4p-2p=6
2p=6
p=3
plz make me braunliest
Answer:
p = 3
Step-by-step explanation:
Given
8p - 4p = 2p + 6, that is
4p = 2p + 6 ( subtract 2p from both sides )
2p = 6 ( divide both sides by 2 )
p = 3

The value of cosine is undefined at pi and 2pi radians.
TRUE
FALSE
Answer: False
Step-by-step explanation:
False, the value of cosine at pi and 2pi is equal to -1 and 1 respectively. You can test this by using the pi circle or a calculator. Let pi = 180 degrees. Cosine is always defined and alternates between 1 and -1.

Answer:
1 foot
Step-by-step explanation:
he used up 3/4 of it so 16x0.75=12 to find remaining length subtract 16-12=4
so there is a 4 foot board left then he gives 1/4 of that to his brother 4x0.25=1
so he gave his brother 1 foot of wood

What's the LCM of 4 and 5?
Answer:
The least common multiply of 4 and 5 is 20.
Step-by-step explanation:
2-(3x+5)=5-2x
i have too answers but need the right one lol
Answer:
x = -8
Step-by-step explanation:
2 - (3x + 5) = 5 - 2x
Subtract 2 from each side.
-(3x + 5) = 3 - 2x
Apply the negative sign in front of the parentheses.
-3x - 5 = 3 - 2x
Add 5 to both sides.
-3x = 8 - 2x
Add 2x to both sides.
-x = 8
We can't have a negative x value, so we'll need to multiply each side by -1.
x = -8
Hopefully, this helped and wasn't too confusing!
Answer:
Solution given;
2-(3x+5)=5-2x
2-3x-5=5-2x
-3-5=3x-2x
x=-8 is your answer

MATH HELP!!! MARKING BRAILIESTT
Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 12 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes , then
y = 3x + c ← is the partial equation
To find c substitute (1, - 2 ) into the partial equation
- 2 = 3 + c ⇒ c = - 2 - 3 = - 5
y = 3x - 5 ← equation of parallel line

O 2(2/5x+2)=4/5x+4
o 2(2/5x+4)=4/5x+2
О2(2/5x+4)= 2 2/5x+8
Answer:
B
Step-by-step explanation:
The equation x + 4 = y can be rewritten as the function f(x) = x + 4 and the equation 2x + 2 = y can be rewritten as the function g(x) = 2x + 2. Complete the table of values for each function.
x | f(x) | g(x)
