Jessie's mom gave her some money to go shopping. She has $100 to spend on new shirts at the store. The store Jessie chooses is having a sale; all shirts cost $10. The function T(s)=10s represents the total cost of the shirts, where s is the number of shirts purchased. What is the domain of T(s) in this context?
Question 9 options:
all non-negative integers that are multiples of 10
all whole numbers
all non-negative rational numbers
all non-negative integers less than or equal to 10
Answers
Answer:
T(s)'s domain is A
Hope This Helps!!!
Answer:
d
Step-by-step explanation:
the shirts are only 10 dollars so that means that the domain is all negative numbers that are either equal to or less than 10, not the multiples.

Which of the following expresses the possible number of positive real
solutions for the polynomial equation shown below?
5x3 + x2 + 7x – 28 = 0
A. One
B. Two or zero
C. Two
D. Three or one
Answers
Answer:
A. OneStep-by-step explanation:
Look at the last term, - 28.
It means, the product of roots is a positive number (28).
The polynomial is a degree three so it has 3 possible roots.
Positive product can be obtained if all 3 numbers are positive or 2 negative and 1 positive.
Therefore number of positive roots is one or three.
Further, double check using the graphical solution (see attached), it shows one root only. It means the other roots are complex.
Correct option is A

Answers
Answer:
Positive
Step-by-step explanation:
It is going up from left to right
Hope this helps
Answer:
Positive.
Step-by-step explanation:
As you go along the x axis and the values of x increase, the values of y also increase. For example, at x = 2 the value of y is 1, and at x = 8 the value of y is 4. This means that the values of y are always increasing as you go up the x axis, so the slope is positive.
You can also tell this from the shape - the line, if read from left to right, is going up, so is positive.
If x+y= -4 and xy=2, then find the value of x²+y²
Answers
Answer:
x² + y² = 12
Step-by-step explanation:
x + y = -4
xy = 2
x² + y² = (x+y)² - 2xy = (-4)² - 2(2) = 16 - 4 = 12
Xy=2
(x+y)^2= x^2+y^2+2xy
(-4)^2=x^2+y^2+2(2)
16 = x^2+y^2+4
x^2+y^2=16-4
Therefore x^2+y^2 = 12

The sum of the measure of angle ∠AXY and angle ∠YXB is the measure of ∠AXB.
The relationship between ∠AXY and ∠YXB is that they are;
Complementary anglesReasons:
From the diagram in the question, we have;
∠BXC = 90° Given
∠BXC and ∠BXA are linear pair angles
Therefore;
∠BXC and ∠BXA are supplementary angles, which gives;
∠BXC + ∠BXA = 180° definition of supplementary angles
Therefore;
∠BXA = 180° - ∠BXC
∠BXA = 180° - 90° = 90°
∠BXA = 90°
∠AXY + ∠YXB = ∠BXA by angle addition property
Which gives;
∠AXY + ∠YXB = 90° by substitution propertyTherefore ∠AXY and ∠YXB are;
Complementary angles, by definition of complementary angles.Learn more about complementary angles here:

Mixed Number: 5 [tex]\frac{7}{10}[/tex]
Improper Fraction:[tex]\frac{57}{10}[/tex]
Step-by-step explanation:
A mixed number is when you express the decimal as a fraction, 0.7 is the same as [tex]\frac{7}{10}[/tex], so 5[tex]\frac{7}{10}[/tex] is your answer.
An improper fraction is a fraction where the numerator is bigger than the denominator, to do this you multipy the whole number 5, which can be written as [tex]\frac{5}{1}[/tex], by [tex]\frac{10}{10}[/tex].
[tex]\frac{5}{1}[/tex]·[tex]\frac{10}{10}[/tex]=[tex]\frac{50}{10}[/tex]
Then add 0.7, or [tex]\frac{7}{10}[/tex].
[tex]\frac{50}{10}[/tex]+[tex]\frac{7}{10}[/tex]=[tex]\frac{57}{10}[/tex]

what is the Greatest Common Factor and the Least common Multiple os 3 and 8
Answers
3 is a prime number - the GCF is 1, and the least common multiple of 3 and 8 is 24.
Answer:
Greatest Common Factor is 1
Least Common Multiple is 24
Step-by-step explanation:
Greatest common factor is the biggest whole number that can be multiplied into the numbers. In this case 1x8=8 and 1x3=3.
Least common multiple is the smallest number each number can multiply into. In this case 3x8=24 and 8x3=24

1, 3, 5 and 7 all have the same angles as well.
look at the example. how would the quotient change if the total number of seats was 3,200 instead of 320? explain
Answers
If the total number of seats is 3200 instead of 320, then the quotient will change by a product of 10
The dividends are given as: 3200 and 320
By comparing 3200 and 320, we have:
3200 > 320 i.e. 3200 is greater than 3203200 = 320 * 10 i.e. 3200 is greater than 320 ten timesQuotient is simply the result gotten from dividing two quantities.
This means that:
If the total number of seats is 3200 instead of 320, then the quotient will change by a product of 10

Answers
Answer:
y = - x + 4
Step-by-step explanation:
First find slope:
6-1/-2-3 = 5/-5 = -1
Then plug one point and slope into point slope form: y-y1 = k (x-x1)
Plug in (3, 1) and slope -1 --> y-1 = -1(x-3)
Simplify --> y - 1 = - x + 4
Then add 1 to both sides --> y = -x + 4
