Olivia bought 7 bags of candy. Each bag cost $1.50. How
much money did she spend on ALL 7 bags of candy?
Answer:
Step-by-step explanation:
7(1.50)=10.5
She spent $10.50 on all bags of candy
Answer:
$10.50
Step-by-step explanation:
So we know that Olivia not only bought 7 bags of candy but that each bag of candy costs $1.50 :
With this information, we can multiply the cost of the bags by the amount Olivia bought, therefore :
[tex]7 * 1.50[/tex]
[tex]= 10.5[/tex]
This means that the amount Olivia bought was $10.50

Pulling out like terms
2.1 Pull out like factors :
x9 - x6 - x3 = x3 • (x6 - x3 - 1)
Trying to factor by splitting the middle term
2.2 Factoring x6 - x3 - 1
The first term is, x6 its coefficient is 1 .
The middle term is, -x3 its coefficient is -1 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is -1 .
-1 + 1 = 0
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
x3 • (x6 - x3 - 1)

Costco marks up the price of a $500.00 couch by 25%
and then has a 25% off sale. What is the selling price of
the couch?
Answer: 468.75
is ya answer
i think
sorry if im wrong
Answer:
468.75
Step-by-step explanation:
First we need to add 25% to 500.00 which is 625.
Next we need to subtract 25% from 625.
Now we have 468.75.
The selling price of the couch is $468.75.

What is the average rate of change of f(x) = 2x^2 - x - 4 over the interval -4 < x < 2?
The average rate of change of f(x) = 2x^2 - x - 4 over the interval -4 < x < 2 is -5.
To find the average rate of change of a function over an interval, we need to calculate the difference in the function values at the endpoints of the interval and divide it by the difference in the x-values.
The given function is f(x) = 2x^2 - x - 4.
Let's calculate the function values at the endpoints of the interval: -4 and 2.
For x = -4:
f(-4) = 2(-4)^2 - (-4) - 4 = 32 + 4 - 4 = 32.
For x = 2:
f(2) = 2(2)^2 - 2 - 4 = 8 - 2 - 4 = 2.
Now, we can calculate the difference in the function values: f(2) - f(-4) = 2 - 32 = -30.
Next, we calculate the difference in the x-values: 2 - (-4) = 6.
Finally, we can calculate the average rate of change by dividing the difference in the function values by the difference in the x-values:
Average Rate of Change = (f(2) - f(-4)) / (2 - (-4)) = -30 / 6 = -5.

Answer:
1. complementary
2. not complementary or supplementary
3. not complementary or supplementary
4. complementary
5. supplementary
Step-by-step explanation:
You can tell if two angles are complementary if their combined angle values add up to 90 degrees
[tex]A+B=90[/tex]
You can tell if two angles are supplementary if their combined angle values add up to 180 degrees
[tex]A+B=180[/tex]
If they don't add up to these values then they are neither complementary nor supplementary

Bidet used a computer algebra system (CAS) to find the quotient of (4x^3+2x^2+3x+5)^2 and x^2+3x+1. Which statement correctly shows a way to enter this problem into a CAS?
A. Division[4x^3+2x^2+3x+5^2, x^2+3x+1]
B. Division[ (4x^3+2x^2+3x+5)^2] [x^2+3x+1]
C. Division[ (4x^3+2x^2+3x+5)^2, x^2+3x+1]
D. Division[2 (4x^3+2x^2+3x+5), x^2+3x+1]
=============================================================
Explanation:
It honestly depends on the CAS program, but for GeoGebra for instance, the general format would be Division[P, Q]
Where,
P = numerator = (4x^3+2x^2+3x+5)^2Q = denominator = x^2+3x+1As another example, let's say we want to divide x^2+5x+6 all over x^3+7 as one big fraction
We would type in Division[x^2+5x+6, x^3+7]

Find the values of x and y.
help please work has to be shown ..
Answer:
x = 7 and y = 17
Step-by-step explanation:
16x + 9x + 5 = 180 cuz they are supplementary
25x = 175
x = 7
We also know that 16x + 4y = 180
so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17

What is the domain of the function
Answer:
C
because it has all the possible inputs for the function
1. Are the polygons similar?
A. Similar
B. Not similar
2. Because...
A. The corresponding sides are congruent, and corresponding pairs of angles all have the same ratio
B. The sides are not the same length as their corresponding sides
C. The corresponding pairs of sides do NOT have the same ratio
The polygons are similar.
This is because dividing the corresponding sides forms the same ratio, as shown by the three equations below
35/28 = 1.25
25/20 = 1.25
(15.5)/(12.4) = 1.25
So the larger figure on the right has side lengths that are 1.25 times larger compared to the corresponding sides of the figure on the left.
You'll need to flip the figure on the left so that the side labeled "20" is along the top, and the "28" is along the bottom.
After this flip happens, also note that the angle arc markings match up. The bottom pairs of angles of each figure are shown with a single arc, while the top angles are shown as double arcs. This helps visually show which angles pair up and are congruent to one another.
Because we have similar proportions as discussed earlier, and congruent pairs of angles like this, this shows the two figures are similar quadrilaterals. The one on the right is simply an enlarged scaled up copy of the figure on the left.

if you have a triangle with a=90 , angle b=50 , find angle c
Answer: m<C = 40
Step-by-step explanation:
Triangle angle sum theorem states that the interior angles of a triangle sum to 180. We have two angles 90 and 50. Now we need to find the third. 90+ 50 +<C = 180. 140+ C = 180. C = 40
Answer:
40
Step-by-step explanation:
sum of angle in a triangle is 180
180=90+50+c
180=140+c
180-140=c
40=c
c=40°
