My bad G <3
Answer:
D: All real numbers or (-∞, ∞)
R: (-∞, 2] or y ≤ 2
------------------------------------------
Domain:
The graphed function has arrows on both ends, meaning that it will extend to -∞ and ∞. Therefore the Domain is:
D: All real numbers or (-∞, ∞)
Range:
The graph extends downward infinitely, so the graph will extend to y = -∞ as x ⇒ -∞ and x⇒ ∞.
The graphed function has a maximum, or greatest y-value at y = 2, therefore:
R: (-∞, 2] or y ≤ 2

Find the set of values of k for which the y = kx – 4 intersects the curve of y = x2 – 2x at two distinct points.
Answer:
For ax^2+bx+c=0,
x^2+x(-2-k)+4=0,
So, b=-2-k,
a=1, c=4, so
(-2-k)^2-(4*1*4)>0,
4+4k+k^2-16>0,
k*2+4k-12>0,
(k+6)*(k-2)>0,
the points of interest are
k=-6, k=2, so
look at k<-6, -6<k<2, and
k>2.
Just plug in values for each
interval and you will see
that k<-6 and k>2.

Find four consecutive even integers whose sum is 100 what are the integers
X → first
X + 2 → second
X + 4 → third
X + 4 → fourth
x + x + 2 + x + 4 + x + 6 = 100
4x + 12 = 100
4x = 88
x = 22
x + 2 = 24
x + 4 = 26
x + 6 = 28
So your integers are 22, 24, 26, and 28.
The explanation is on the picture please help me with my math
Answer:
Step-by-step explanation:
1. add 8 to both sides to get d=25
2. subtract 12 from both sides to get v=-17
3. add 2 to get b=-9
4. subtract m to get -16-m=71 then add 15 to get -m=87 then divide both sides by - to get m by itself so m=-87
5. subtract a then subtract 29 to get -a=-105 then divide it by - to get a=105
6. add 14 to both sides to get y=12

the angles of a qaudileteral are x,2x,100 and 110 degress find the value of 2x
Step-by-step explanation:
Hey there!!!!
We generally sum up all the angles to get 360° as per given in our question.
Here, in your question, we have values as,
x, 2x, 100°, 110°.
(We have 360° as the sum quadrilateral).
So, x° + 2x° + 100°+110° = 360°
3x°+210°= 360°
3x° = 360° - 210°
or, 3x° = 150°
[tex]x = \frac{15 0 }{3} [/tex]
Therefore the measure of 2x is (2×50)°=100°.
Hopeit helps...
Answer:
X=50; 2x=2×50=100
Step-by-step explanation:
sum of angles in a quadrilateral is 360°
Therefore; x+2x+100+110=360;
3x+210=360;
3x=360-210;
3x=150;
divide both sides by the co-efficient of x;
3x/3=150/3;
x=50;
therefore 2x=2×50;
2x=100.

If x < 0 and y > 0, where is the point (x, y) located?
If the sum of two consecutive number is 71 and one number is x then the other number is options are x +(x+1)=71,x+(x+2)=71,x+x=71,none of these
A consecutive number is a number directly following another number.
For instance, 1 and 2 are consecutive numbers
So x + (x + 1) = 71 is the only correct choice
solve for x please!

Answer:
20,000.
Step-by-step explanation:
The first music player has 500 songs stored by 2 GB. So 500/2 is 250. You take 250 and you multiply it by 80 and you get 20,000.

Every weekday after tennis practice, Will buys either a carton of milk or a bottle
of power drink.
Suppose that m is the number of cartons of milk that Will purchased during
the last month. His total cost for beverages in dollars last month can be
represented by the algebraic expression 2m + 3 (20 – m).
Which of the following statements are true? Select all that apply.
The cost of the power drink is $3 per bottle,
Will purchased 20 more bottles of power drink than cartons of milk.
Will purchased a total of 20 beverages during the last month.
The total amount Will spent on power drinks was $60
An equivalent expression for the total cost of Will's beverages during this month is
60 - m dollars
Will purchased 20 more cartons of milk than bottles of power drink
Answer:
The correct options are;
The cost of milk powder is $3 per bottle
An equivalent expression for the total cost of Will's beverages during this month is 60 - m dollars
Step-by-step explanation:
The given information are;
The items Will buys every weekday after tennis practice = A carton of milk or a bottle of powder drink
The number of milk purchased during the month = m
Will's total cost for beverages in dollars last month = 2·m + 3·(20 - m)
1) Therefore, given that the total amount is factored in dollars, we have;
2·m and 3·(20 - m) are dollar amounts, while, m is a quantity;
Therefore;
Where;
2·m = The total cost of the cartons of milk, then the factor 2 represents $2.00 which is the cost per carton of milk
Similarly, 3·(20 - m) can be said to represent the total cost of the powder drink then the factor 3 represents $3.00 which is the cost per powder drink and the factor (20 - m), represents the number of powder drink Will buys for the month
From which we found the cost of milk powder = $3.00 per bottle
2) The expression, 2·m + 3·(20 - m) simplifies to 2·m + 60 - 3·m, which gives;
2·m + 60 - 3·m = 60 - m which is an equivalent expression for the total cost of Will's beverages for the month.
