Which expression is equivalent to Oy-3?
O 3ty-1)
O 3(3-1)
O 9(y-3)
O 9(3y-3)
Answer:
3(3y-1)
Step-by-step explanation:
To find out which expression is equivalent, expand and simplify the options listed to see which one equals 9y-3.
Let's try the second option. To simplify the expression, use the distributive property. So, multiply each term in the parentheses by 3:
[tex]3(3y-1)\\= 9y-3[/tex]
Thus, the answer would be the second option.

How do you solve this
Answer:
x<-3
Explanation:
Divide both sides by -2 to isolate x.
Since you have divided by a negative number and it changed the positive number to a negative one, you'll need to change the direction of the sign to now reflect that.

3.3(x + 1.2) = 40.26
Answer: x=11
Step-by-step explanation:
Answer:
x = 11
Step-by-step explanation:
3.3(x + 1.2) = 40.26
Distribute the 3.3 across the parentheses.
3.3x + 3.96 = 40.26
Combine the constants by subtracting 3.96 from both sides
3.3x = 36.3
Isolate the variable by dividing both sides by 3.3
x = 11
Check your work by plugging x = 11 into the original equation.
3.3(11 + 1.2) = 40.26
3.3(12.2) = 40.26
40.26 = 40.26
Your answer is correct.
Hope this helps!
Factorise x cubed - x
Answer:
= x(x+1)(x-1)
Step-by-step explanation:
Given the expression x³ - x
On factorizing
x³ - x
= x(x²-1)
Using difference of two square
a² - b² = (a+b) (a-b)
x² - 1
= x² - 1²
= (x+1)(x-1)
The complete factor
x³ - x
= x(x²-1)
= x(x+1)(x-1)

8kg ham costs $12/kg. find the cost per pound.
Answer:
The cost per pound is: $5.45 per pound
Step-by-step explanation:
Given
8kg ham costs $12/kg
To determine
Find the cost per pound
As
1 kg = 2.2 pounds
Weight of 8kg in ponds = 8 × 2.2 = 17.6 ponds
Cost of ham/pound = $12/2.2 pounds
= $5.45 per pound
Thus, the cost per pound is: $5.45 per pound

Write the equation of a line in slope-intercept form that is contains a slope of -0.32 and
a y intercept at (0, 4.75).
Answer:
y = -0.32x + 4.75
Step-by-step explanation:
Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. (For example: y = 2x + 1)
Since you have the slope, or m, is -0.32 and the y-intercept, or b, is 4.75, you can plug those into the equation to get y = -0.32x + 4.75
if you spent 6 hours a week studying for English and 2.5 hours studying for math what is the ratio of time spent studying in math to studying for English ?
Answer: If you spend 7 hours a week studying for English, and 4.5 hours studying for math what is the ratio of time spent studying math to studying English?
Math: English
4.5: 7 Now you divide both sides by 4.5 to get 1 on one side
1: 1.555556
So the ratio of time spent studying math to english is 1 to 1.555556. Hope I helped
Hayden invested $200 in a savings account that earned 3.3% simple interest each year. William invested $300 in a savings account that earned 2.5% simple interest each year. Neither Hayden nor William add or take out money from their accounts. Hayden claims that she will earn more interest on her account than William after 2 years because she has a greater interest rate. Do you agree with Hayden? Why or why not? Be sure to defend your answer with numbers.
Answer:
No i do not agree
Step-by-step explanation:
During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her
descent at a rate of 23 feet per minute. Enter an inequality you could solve to find the number of minutes
she can continue to descend if she does not want to reach a point more than 97 feet below the ocean
surface. Use t to represent the variable for the minutes Lainey can continue to descend.
The inequality is
t (select)
t (23) ≤ 97 - 23
The minus 23 at the back represents the feet she already descended before what the question wants us to calculate
≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)
In the figure above, are <3 and <7 alternate interior angles,
same-side interior angles, corresponding angles, or alternate
exterior angles?
Answer:
Corresponding angles
Step-by-step explanation:
<3 and <7 lie on the same side of the transversal line. Each angle also is located on the outside of each parallel lines cut across by the transversal.
Therefore, <3 and <7 are corresponding angles.

Given t4 = 187.5 and r = 2.5
a. Find the value of t1.
b. Write an explicit formula for this sequence.
c. Find the value of t18.
Answer:
a) [tex]t_{1} = 12[/tex]
b) The explicit formula
[tex]t_{n} = ar^{n-1} = 12(2.5)^{n-1}[/tex]
c) t₁₈ = 69,849,193.096
Step-by-step explanation:
Step(i):-
Given that the geometric sequence
r = 2.5
Given the fourth term of the geometric sequence
[tex]t_{4} = ar^{3} = 187.5[/tex]
⇒ ar³ = 187.5
⇒ a (2.5)³ = 187.5
[tex]a = \frac{187.5}{(2.5)^{3} } = 12[/tex]
The explicit formula
[tex]t_{n} = ar^{n-1} = 12(2.5)^{n-1}[/tex]
Step(ii):-
put n=1
[tex]t_{1} = ar^{1-1} = 12(2.5)^{1-1} = 12 (2.5)^{0} = 12[/tex]
The [tex]18^{th}[/tex] of the geometric sequence
[tex]t_{18} = ar^{18-1} = a r^{17}[/tex]
[tex]t_{18} = 12( 2.5)^{17}[/tex]
t₁₈ = 69,849,193.096
Final answer:-
a) [tex]t_{1} = 12[/tex]
b) The explicit formula
[tex]t_{n} = ar^{n-1} = 12(2.5)^{n-1}[/tex]
c) t₁₈ = 69,849,193.096
Twelve is not equal to negative four
Ok?? thx for the points
Hi there!
Twelve is not equal to negative four.
So we know that all of the factors of twelve is 1,2,3,4,6, and 12 itself...
None of these are actually -4 since -4 doesn’t equal to 12.
Think about this... when your trying to multiply or add...
[tex]-4+-4=0[/tex]
[tex]0+-4=-4[/tex]
[tex]-4[/tex]·[tex]-4=16[/tex]
If you keep on multiplying or adding it, it’ll always stay the same...
So like always, twelve isn’t equailvalent to -4.
Q11.
The diagram shows a trapezium.
x-4
Diagram NOT
accurately drawn
2x
x + 5
All the measurements are in centimetres.
The area of the trapezium is 351 cm2.
(a) Show that 2x2 + x - 351 = 0
Answer:
Step-by-step explanation:
The area of a trapezium is given as;
Area = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the length of the upper side, b is the length of its base and h is its height.
This implies that; a = x - 4, b = x + 5, h = 2x and area = 351
Thus,
351 = [tex]\frac{1}{2}[/tex]((x - 4) + (x + 50)) 2x
= (x - 4 + x + 5) x
531 = (2x + 1) x
= 2[tex]x^{2}[/tex] + x
So that;
2[tex]x^{2}[/tex] + x - 531 = 0
This gives a quadratic equation.

CALCULUS: For an object whose velocity in ft/sec is given by v(t) = sin(t), what is its distance, in feet, travelled on the interval t = 1 to t = 5?
A. 0.45
B. 2.82
C. 0.03
The linked answer is wrong because that integral gives you the net displacement of the object, not the total distance.
To get the distance, you have to integrate the speed (as opposed to velocity), which involves integrating the absolute value of the velocity function.
[tex]\mathrm{distance} = \displaystyle\int_1^5 |\sin(t)| \,\mathrm dt[/tex]
By definition of absolute value,
[tex]|\sin(t)|=\begin{cases}\sin(t)&\text{for }\sin(t)\ge0\\-\sin(t)&\text{for }\sin(t)<0\end{cases}[/tex]
Over this particular integration interval,
• sin(t ) ≥ 0 for 1 ≤ t < π, and
• sin(t ) < 0 for π < t ≤ 5
so you end up splitting the integral at t = π as
[tex]\mathrm{distance} = \displaystyle\int_1^\pi \sin(t)\,\mathrm dt + \int_\pi^5 (-\sin(t))\,\mathrm dt[/tex]
Now compute the distance:
[tex]\mathrm{distance} = -\cos(t)\bigg|_1^\pi + \cos(t)\bigg|_\pi^5[/tex]
[tex]\mathrm{distance} = -(\cos(\pi) - \cos(1)) + (\cos(5) - \cos(\pi))[/tex]
[tex]\mathrm{distance} = -2\cos(\pi) + \cos(1) + \cos(5) \approx 2.82[/tex]
making B the correct answer.
How do you decide whether the larger unit rate or the smaller unit rate is the better buy? Please help me.
Answer:
The smaller unit rate is a better buy
Step-by-step explanation:
Given
Larger unit rates and smaller unit rates
Required
Determine which is a better buy
To answer this, I'll use the following assumptions.
If store A and store B sell the same product at $2/ unit and $3/ per unit respectively.
At store A (with $2/unit), you will get 50 of that product at 50 * 2 = $100
At store B (with $3/unit), you will get 50 of that product at 50 * 2 = $150
Meaning that, you will spend more at the store with the larger unit rate (and you don't want that, do you?)
Hence, the smaller unit rate is a better buy.
