What is the equation of the line that passes through point (-1,4) and is perpendicular to the following equation? y= -1/2x - 4
Answers
Answer:
y=2x-4
Step-by-step explanation:
To find an equation perpendicular to another one, you must find the negative inverse of the slope.
In this case, -1/2 has an inverse of -2, but because we're finding the negative inverse, the two negatives cancel out and we get 2, the slope of our perpendicular equation, which crosses the initial equation, making a right angle.

TRUE
FALSE
Answers
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.
Does the equation represent a linear or nonlinear function?
y=x2+3
Answers
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.
If C = x2 + 8x + 3 and B = x – 8, find an expression that equals 3C + B in

Answers
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
MATH HELP!!! MARKING BRAILIESTT
Answers
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

Answer:
Linear
Step-by-step explanation:
Linear it forms a straight line when it graphed. It also has a slope and a constant.
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be
0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1.

Step-by-step explanation:

2-(3x+5)=5-2x
i have too answers but need the right one lol
Answers
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

person's mass. A person with a mass of 100 kg contains 66kg of water. How many
kilograms of water are in a person with a mass of 150 kg?
please help asap !!!
Answers
KgW equals kg of water
Just use ratios to get the answers and solve for X.
100kgP/66kgW=150kgP/X
X= 150 kgP * 66 kgW / 100 kgP
X= 99 kgW
So 99 kg of water in a 150 kg person
