Which ordered pairs are solutions to the equation 3x - 2y = 12 ? (hint: plug in the x and y values into the equation to see if it makes a true statement.) Group of answer choices (1,-4.5) (5,-1.5) (2,-3) (0,6) (-2,3) (-2,-9)
Answer:
1,-4.5
Step-by-step explanation:
Answer:
(-2,-9) is the answer
3x - 2y = 12
3(-2) - 2(-9) = 12
-6+18 = 12
12 = 12
I really need help please, any Expert willing to help me out? I don’t understand on #2, for a,b, and c.
Step-by-step explanation:
a) Tangent equals sine divided by cosine. Therefore:
tan(-t) = sin(-t) / cos(-t)
b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):
tan(-t) = -sin(t) / cos(t)
tan(-t) = -tan(t)
c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function). Therefore, y = tan(t) is symmetric about the origin.

the difference of a number and ten is at least 91
Answer:
x-10 [tex]\geq[/tex] 91
Step-by-step explanation:
Difference means subtraction, and "a number" since not specified is x, and at least means greater than or equal to and not less than. So the difference (subtract) of a number (x) and 10 is at least (greater than or equal to) 91 :D

A square has a perimeter of 12x + 40 units. Which expression represents
the side length of the square in units? *
X + 4
O x + 40
O 3x + 10
3x + 43
Answer:
3x+10
Step-by-step explanation:
Since the perimeter of a square is 4 times the side length, to find the side length given the perimeter, just divide by 4:
(12x+40)/4 = 3x+10
Therefore, the answer is 3x+10

A curve has equation y = x
3 − 4x
2 + 2x
Find the x coordinate of each of the points on the curve at which the gradient of the tangent to the
curve is 2
Answer:
The derivative (or gradient function) describes the gradient of a curve at any point on the curve. Similarly, it also describes the gradient of a tangent to a curve at any point on the curve.
To determine the equation of a tangent to a curve:
Find the derivative using the rules of differentiation.
Substitute the \(x\)-coordinate of the given point into the derivative to calculate the gradient of the tangent.
Substitute the gradient of the tangent and the coordinates of the given point into an appropriate form of the straight line equation.
Make \(y\) the subject of the formula.
The normal to a curve is the line perpendicular to the tangent to the curve at a given point

-2b+2(b-10)=2(10+5b)
Answer:
b= -4
Step-by-step explanation:
On both sides of the equation has distributive property. We need to solve that first. Let's start with the left side of the equation.
*Positive multiplied by a negative equals a negative
-2b+2(b-10)= 2(10+5b)
-2b+2b-20= 2(10+5b)
-20= 2(10+5b)
Now let's solve the right side of the equation
-20= 20+10b
-20 -20
-40 = 10b
-40/10 = 10b/10
b= -4

suppose the probability you will get an A in this class is .25 and the probability you will get a B is .50. What is the probability your grade will be above a C?
Answer:
75% chance
Step-by-step explanation:
Probability always adds to 1.00
Letter grades are always in the form A, B, C, D...
The grades above a C are A, which is a 25% chance and B, which has a 50% chance. Adding these up we get a 75% chance.
#LearnWithBrainly
The probability of getting a grade above a C is 0.75, or 75%.
We have,
To calculate the probability of getting a grade above a C, you need to add the probabilities of getting an A or a B.
Given:
Probability of getting an A (P(A)) = 0.25
Probability of getting a B (P(B)) = 0.50
A grade above a C includes grades of A and B.
Therefore, the probability of getting a grade above a C (P(above C)) is:
P(above C) = P(A) + P(B)
P(above C) = 0.25 + 0.50
P(above C) = 0.75
Thus,
The probability of getting a grade above a C is 0.75, or 75%.

What is (x+4)(3x+7)/(x+4)(x+2) simplified?
Answer:
[tex]\frac{3x+7}{x+2}[/tex]
Step-by-step explanation:
Given the following question:
[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
In order to simplify the expression given we can only cancel the common factor which is four.
[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
[tex]cf=(x+4)[/tex]
[tex]\frac{x+4}{x+4}[/tex]
[tex]=\frac{3x+7}{x+2}[/tex]
Cannot be simplified further due to it not having any more common factors. Your answer is "3x + 7 / x + 2."
Hope this helps.
Answer:
( 3x+7 ) / ( x+2 )
Step-by-step explanation:
\frac{(x+4)(3x+7)}{(x+4)(x+2)}
When you set up the equation like a fraction, you can now cancel out like terms. (x+4) is in the denominator- as well as the numerator. They are the same in parentheses. So you can cancel. Once that's done, you'll be left with
\frac{3x+7}{x+2}
You cant simplify any further because there are no more (like groups) aka (common factors)
( 3x+7 ) / ( x+2 )
How many square feet of carpet are needed to cover the floor of a rectangular room 18 ft. by 12 ft.?
Answer: Area of the rectangular room = length x Breadth
Length= 18 and Breadth = 12
Therefore the Area required to cover the floor = 18 * 12 = 216 ft2
The area of the rectangular room is given by the equation A = 216 feet²
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
