Are 4(a - 3) and 4a - 7 equivalent expressions?
Answer:
Yes
Step-by-step explanation:
Given expression: 3x+9
Take 3 outside from the expression, we get,
= 3(x+3), which is called the equivalent expression
Answer:
No
Step-by-step
We have to multiply the 4 by both the a and the 3 since there a parenthesis around them. This would of course be distributive property. Since you don't know what a is, it would just be 4a and since we can multiply 4 and 3 that would be 12. So, 4(a - 3) is equivalent to 4a - 12.

Answer:
y = 5/4 x + 9
y = -5x+4
Step-by-step explanation:
a)The equation of the line in slope intercept form is expressed as y = mx+b
m is the slope
b is the intercept
Given
Slope m = 5/4
y-intercpet = 9
Substitute
y = mx+b
y = 5/4 x + 9
b) Given the coordinates (0,4) and (2, -6)
Slope m = -6-4/2-0
m = -10/2
m = -5
Since the y intercept of the line is (0, 4), hence b = 4
Get the equation
Recall
y = mx+b
y = -5x +4
This gives the required equation

The area of a rectangle is represented by the expression 2x2 + 10x + 12. Daniel is convinced that the dimensions of this rectangle could be (2x + 4) and (x + 3) or (x + 2) and (2x + 6). Do you agree or disagree with Daniel? Use words to justify your opinion.
Answer:
I agree with daniel
Step-by-step explanation:
Given the area of a rectangle expressed as;
A(x) = 2x²+10x+12
On factorizing;
A(x) = 2x²+6x+4x+12
A(x) = 2x(x+3)+4(x+3)
A(x) = (x+3)(2x+4)
since A(x) = l(x)w(x)
Hence the legnth and width of the rectangle are 2x+4 and x+3.
Also A(x) = 2x²+6x+4x+12 can be factorized as;
A(x) = 2x²+4x+6x+12
A(x) = 2x(x+2) + 6(x+2)
A(x) = 2x+6(x+2)
Therefore I agree with Daniel. The factor differs due to the difference in arrangement of 4x and 6x in the expression. Precedence of values affects the final factors

As a first step in solving the system shown, Yumiko multiplies both sides of the equation 2x – 3y = 12 by 6. By what factor should she multiply both sides of the other equation so that she can add the equations and eliminate a variable?
5x + 6y = 18
2x – 3y = 12
Answer:
3
Step-by-step explanation:
First, we can start by multiplying the equation 2x - 3y = 12 by six to see where that gets us,
2x - 3y = 12 --> 12x - 18y = 72
12x - 18y = 72
5x + 6y = 18 (other equation)
We can notice that eliminating the y term would be the easiest to go about, so we want to find the number that we can multiply 6 by to get 18. That number is 3, so the factor is 3.
You can use the fact that non of 2 times 6 doesn't include 5 as factor.
There are two possible values of the factor by which if Yumiko multiplies the first equation and add the equations, a variable is eliminated.
Those values of the factor are [tex]3[/tex] (for elimination of y) or [tex]-\dfrac{12}{5}[/tex] (for elimination of x)
How to find by what factor should we multiply the equations to eliminate a variable in a system of linear equations of two or more variables?Our aim in doing so is to make the coefficients of same variable equal and with opposite signs so that when we add the equations, that variable gets eliminated because of coefficient becoming zero.
For example, take the given equations and the factor by which Yumiko multiplied the second equation.
5x + 6y = 18
2x – 3y = 12 => 12x - 18y = 72 (since she multiplied this with 6)
Let she multiply the first equation with factor "p"
Then we will have the system as;
[tex]p \times 5x + p \times 6y = p \times 18\\12x - 18y = 72[/tex]
Adding both the equations, we get:
[tex](5p + 12)x + (6p - 18)y = 18p + 72[/tex]
Since there are two variables and since any one of them can be eliminated depending on the value of p, thus we have two cases:
Case 1: Eliminated variable is xThen we have coefficient of x = 0
or
[tex]5p + 12 = 0\\5p = -12\\p = -\dfrac{12}{5}\\[/tex]
Case 2: Eliminated variable is yThen we have coefficient of y = 0
or
[tex]6p - 18 = 0\\6p = 18\\p = \dfrac{18}{6} = 3[/tex]
Thus, there are two possible values of the factor by which if Yumiko multiplies the first equation and add the equations, a variable is eliminated.
Those values of the factor are [tex]3[/tex] or [tex]-\dfrac{12}{5}[/tex]

It's physics, right?
A. will have box 2.
B. will have box 1
C. will have box 3
Answer:
Part A will be the 2nd line
Part B will be the 1st line
Part C will be the 5th line
*note* I don't know if these lines move as you move them so I getting these answers as if they do not move.
Step-by-step explanation:
Let's start with part A.
It says he rides quickly. This means that as the distance increases, the time will increase slower.
So we are looking for a steep line. The steepest lines are line 2, 3 and 4
We know it can not be the 4th line because these line shows that time is no longer moving, just the distance.
Since it is impossible to freeze time, line 4 does not make any sense. So let's look at line 2 and 3
This can be confusing because it says down hill. So you may think it is line 3. When Cole goes down the hill, he is getting further from home. This means the line has to go up.
So that means part A has to be line 2.
Now let's start with part B
When graphing distance and time, if someone stops, their line stops moving in one direction too.
If you stop moving, you are not gaining any distance but time still moves.
This means we are looking for a line that moves in only 1 direction. These lines are lines 1 and 4.
On line 1, only time is moving
On line 4, only distance is moving
So like I said before, it is impossible to move while time is not moving. So line 4 makes no sense again. Leaving us with line 1.
So part B is line 1
Now we will do part C
It says that Cole rides slowly.
This means the line will not be steep. He is also still moving so it can not be line 1.
So we have line 5 and 6.
Since he is still moving away from the house, the line has to go up in distance and time. So this eliminates line 6
This leaves us with line 5
So the answer to part C is line 5
Hope this helps and have a great day!

Answer:
Tan.
Step-by-step explanation:
First way;
Tan (90-θ )=Cot θ Tan (90+θ )= -Cot θ
1st explanation, QUOTATIONS!
"tan90∘ is undefined because you can't divide 1 by nothing. Nothing multiplied by 0 will give an answer of 1 , so the answer is undefined."
2nd explanation, QUOTATIONS!
"That's undefined because as you approach 90° from either direction, tan approaches positive or negative infinity. cot(90°) hence approaches 1/infinity (either positive or negative) which is just 0."

Step-by-step explanation:
Remember that perimeter is the measure of the outer edge of a shape, or otherwise, the sum of the measures of the sides of the trapezoid. Representing the perimeter by P, and the sides as a, b, c and d, our formula is P = a + b + c + d.

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Money is invested in a saving account at 12% simple interest.
And, After one year there is $1680 in the account.
Now,
Let the original invested amount = x
So, We can formulate;
⇒ x + 12% of x = 1680
⇒ x + 12x/100 = 1680
⇒ 112x = 1680 × 100
⇒ 112x = 1,68,000
⇒ x = 1,68,000/112
⇒ x = $1,500
Thus, The original invested amount = $1,500

If 8 boxes of cereal cost $27.60, what is the price of one box?
Answer:
$3.45
Step-by-step explanation:
Let "x" repreesnt the cost of one box. If 8 = 27.60, 1 = "x". Set up a fraction, then solve;
[tex]\frac{8}{27.6}=\frac{1}{x}[/tex]
Step 1: Divide 27.6 by 8
[tex]27.60 \div 8 = 3.45[/tex]
Step 2: Multiply the result by 1
[tex]3.45 \times 1 = 3.45[/tex]
That means 1 cereal box costs 3.45 dollars.
