Intro
Answer:
y=-x2 - 8x – 18 is shown by graph D.
y=x2 - 4x + 7 is shown by graph A.
y=X+5 is shown by graph C.
y=-3x - 6 is shown by graph B.
Step-by-step explanation:
In y=-x2 - 8x – 18, the coefficient of x2 is less than 0.So the graph only has a maximum value.Thefore , the graph is point upward.
In y=x2 - 4x + 7, coefficient of x2 is greater than 0.
So the graph has a minimum point and is pointed downward.
for y =x + 5, the gradient is positive.so it is graph C.There is another way to find out too but this is quicker for now.
for y = -3x - 6, the gradient is negative ,-3.So it is the graph B.

If 1/4in on a map represents 1 meter, how many meters does 4/5in represent?
Answer:
3 1/5 meters
Step-by-step explanation:
1/4 in. on map ⇒ 1 meter in real life
1/4 can also be written as 5/20⇒ 1/20 = 1/5 meter⇒ 4/5 in. = 16/20 inches
⇒ 16/20 inches = 1/5 x 16 = 3 1/5 meters

the sum of the digits of a two - digit number is 14 . if the digits are reversed, the number increases by 36 . find the number .
Let the tens digit of the number be x .
ones digit = ( 14 - x ) ( since the sum of the 2 digits is 14 )
Two - Digit number = 10 ( tens digit ) + ones digit
Required number ,
10x + ( 14 - x ) 10x - x + 14 9x + 14Reversed number ,
10 ( 14 - x ) + x 140 - 10x + x 140 - 9xGiven ,
Reversed number - Required number = 36
✯ 140 - 9x - ( 9x + 14 ) = 36
✯ 140 - 9x - 9x - 14 = 36
✯ 126 - 18x = 36
✯ 126 - 36 = 18x
✯ 18x = 90
✯ x = 5
Ten digits , x = 5 Ones digits = ( 14 - x ) = 14 - 5 = 9♧ Thus , Required number is 10 × 5 + 9 = 59
Given -
the sum of the digits of a two - digit number is 14.i.e, if two numbers are x and y then, x + y = 14
if the digits are reversed, the number increases by 36i.e, if 10y + x then 10y + x = 10x + y + 36.
To find -
the numberConcept -
If a, b and c are real number (and if a and b both are not equal to 0) then ax+by=c is called a linear equation in two variables (The two variables are x and y)
The numbers a and b are called the coefficient of the equation ax+by=c. The number r is called the constant of the equation ax+by = c
PS - first we will construct two linear equations and then we'll find the number.
Solution -
Let, x + y = 14
➜ y = 14 - x ----(i)
and we'll solve 10y + x = 10x + y + 36 further,
➜ 10y + x = 10x + y + 36
➜ 10y - y = 10x - x + 36
➜ 9y = 9x + 36
➜ 9x - 9y = -36
➜ 9(x - y) = -36
➜ x - y = -4 ----(ii)
Substituting the value of y (in equation (i)) in equation (ii),
➜ x - (14 - x) = -4
➜ x - 14 + x = -4
➜ 2x = -4 + 14
➜ 2x = 10
➜ x = 10/2
➜ x = 5
Now to find the value of y we will substitute the value of x in equation (i),
➜ y = 14 - 5
➜ y = 9
Therefore, the number is {10(5)+9,i.e,} 59.

Find the values of x and y. Write your answers in the simplest form.
Answer: [tex]x=18[/tex] ; [tex]y=6\sqrt{3}[/tex]
Step-by-step explanation:
You can write two expressions that are in terms of 'x' and 'y'. This is a right triangle, so Pythagorean's theorem can be used. We can also use the angle to find the sine of 30 degrees.
Pythagorean's Theorem:
The values 'a' and 'b' are the two shorter sides of the triangle, while the value 'c' is the longest side of the triangle; the hypotenuse.
[tex]a^2+b^2=c^2[/tex]
[tex]x^2+y^2=(12\sqrt{3} )^2[/tex]
[tex]x^2+y^2=12^2*\sqrt{3} ^2=432[/tex]
Sine of the Angle:
Sine is defined to be the opposite side divided by the hypotenuse. Let's take the sine of 30 degrees:
[tex]sin(\alpha )=opposite/hypotenuse[/tex]
[tex]sin(30)=y/12\sqrt{3}[/tex]
[tex]\frac{1}{2} =y/12\sqrt{3}[/tex]
[tex]y=6\sqrt{3}[/tex]
Plug this value of 'y' into the first expression derived from Pythagorean's theorem:
[tex]x^2+y^2=432[/tex]
[tex]x^2+(6\sqrt{3} )^2=432[/tex]
[tex]x^2+108=432[/tex]
[tex]x^2=432-108=324[/tex]
[tex]x=\sqrt{324}[/tex]
[tex]x=18[/tex]
Use this value of 'x' to solve for 'y' in the expression from Pythagorean's theorem:
[tex](\sqrt{324})^2+y^2=432[/tex]
[tex]324+y^2=432[/tex]
[tex]y^2=432-324=108[/tex]
[tex]y=\sqrt{108}[/tex]
[tex]y=\sqrt{36*3}[/tex]
[tex]y=6\sqrt{3}[/tex]

1. Mrs. Rodger got a weekly raise of $145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
weekly raise= $145
solution:let's assume the first paycheck as x.
she got a weekly raise of $145.
So, after concluding the first week she'll get $ (x+145).
likewise, after completing the second week she'll get $ (x + 145) + $ 145.
= $ (x + 145 + 145)
= $ (x + 290)
therefore, this is how her salary will get increased by $145 at the end of every week.
Miguel cut 1/4 from a round pie. Mariah cut a piece from the same pie with an angle measure of 60 degrees who cut the larger piece? Explain.
Answer: Since the pie is round it is a circle, and all circles have 360 degrees in total. Miguel cut 1/4 of the pie and 1/4 x 360 = 90. 90 is greater than 60.
Step-by-step explanation:
Answer:
Miguel has the larger piece. 1/4 is equal to 90, because 360/4 = 90.
So Miguel has the larger piece

Tristan is comparing two number patterns based on the information below.
Both patterns start with the number 1.
Pattern A follows the rule “add 3”.
Pattern B follows the rule “add 4”.
How does each of the first 5 terms in Pattern A compare to the first 5 terms in Pattern B?
As part of your answer, list the first 5 terms of each pattern.
Explain your answer.
Pattern A = 1, 4, 7, 10, 13
Pattern B = 1, 5, 9, 13, 17
Each term is increases at a faster rate in pattern B; the difference between terms increases by one per step. In pattern A, 1 jumps to 4, while in pattern B, 1 jumps to 5. There is a difference of one. But when in pattern A, 4 jumps to 7, in pattern B, 5 jumps to 9. The is a difference of two between these two terms even though they are on the same "jump." This difference increases by one per "jump." (Jump is not the official word for this but I'm assuming this isn't a sequence problem.)

A total of 590 tickets were sold for the school play. They were either adult tickets or student tickets. There were 60 fewer student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
325 adult tickets
Step-by-step explanation:
This "sum and difference" problem can be solved by assigning a single variable to the quantity you want to know. Let 'a' represent the number of adult tickets sold. Then (a-60) is the number of student tickets sold, and the total number sold is ...
a +(a -60) = 590
2a = 590 +60
a = 650/2 = 325
There were 325 adult tickets sold.
__
Check
325-60 = 265 student tickets were sold, for a total of 325+265 = 590.
_____
Additional comment
You may have noticed that the larger number of tickets (number of adult tickets) was found to be the average of the two numbers given in the problem statement. That will generally be the case for a "sum and difference" problem.
