The coordinates of a parallelogram are given segment AB is parallel to the x-axis determine the values for a,b,c,d
Answer:
a=3 d=1 b and c cant be solved
Step-by-step explanation:
because segment AB is parallel to x axis . So the slope of ABco is 0. So the y value is congruent
a=3 d=1
We know AB=CO b+2=8-C
we can only find ad, but we could not get b,c

О А. 3х³ - 24х-9
О B. х-8х-3
0 С. 3x²-5x-6
O D. 3x²-6x+15
Answer:
A
Step-by-step explanation:
You have to simplify the brackets in turn.
3 times x^3- 7x+1 = 3x^3- 21x+ 3
then do 3 times x + 4= 3x + 12
you then add them all together, if they have a power add them, if they just have an x add them, and if they are just a number add them.
So it goes to 3x^3- 24x - 9,
this is because 3x^3 cant be added/ subtracted by anything, -24x is made from -21x- 3x, and -9 is made from 3 - + 12, so this means 3 - 12 = -9.
I hope this helps, have a lovely day.
solve the inequality 1/2b+2≤8
1/2b+2≤8
1/2b≤6
b≤12
Any number less than or equal to 12 can solve the equation.
Answer
[tex]b\leq 12[/tex]
Step-by-step explanation
You would subtract two from the eight and that would get you six, and the reciprocal of 1/2 is two so technically you would multiply the 6 by two and that gets you 12.
Hope this helps any!

How do I solve x - 6 1/2 = 3 2/3
Pls explain ur answer and how I can improve I’m having math finals
Answer:
10 1/6
Step-by-step explanation:
First, you need to turn all the mixed numbers into improper fractions. You do this by multiplying the whole number by the denominator, adding the numerator, and then putting that number over the denominator.
So, 6 1/2 would become (6(2) + 1)/2 = 13/2. And 3 2/3 would become (3(3) + 2)/3 = 11/3.
Then, you can rewrite your equation using the improper fractions:
x - 13/2 = 11/3
Then, add 13/2 to both sides since it is being subtracted:
x = 13/2 + 11/3
Add the fractions by multiplying the denominators of each by the fraction of the other:
3(13/2) = 39/6
2(11/3) = 22/6
Add the fractions:
39/6 + 22/6 = 61/6
Simplify the fraction:
10 1/6
Answer:
10 1/6 or [tex]10\frac{1}{6}[/tex]
Step-by-step explanation:
The BEST, BASIC, FAST trick to find x in these situtations
If you have to find x in a question which is having Subtraction, then you add what number was being subtracted or what was subtracting the x or variable with the ending result. If you're doing addition, then you do subtraction in the same way.
Multiplication -> Division
Divisioin -> Multiplication
these 2 also in the same way!
Why do to do this?
Because when we will add that number with the final result, then we will get what is x, since x-that number = the last number. Try to understand, it's pretty hard to explain.
Now, solving the problem!
[tex]6\frac{1}{2} +3\frac{2}{3} =\\\\6\frac{3}{6} +3\frac{4}{6} =\\\\10\frac{1}{6}[/tex]
So your answer is 10 1/6 or [tex]10\frac{1}{6}[/tex]

A hotel with 80 rooms has 45 for doubles
and 35 singles. Singles can be booked in
any room, but reservations for two or
more people must be booked in double
rooms.
Let x be the number of single reservations and y
the number of reservations for two or more.
Which system of inequalities represents this
situation?
Click on the correct answer.
x ≥ 35 x + y ≤ 80
y ≤ 45 x + y ≤ 80
x≤ 35 x+y≤ 80
y≥ 45 x + y ≤ 80
Answer:
y ≤ 45
Step-by-step explanation:
First y must be less than or equal to 45.
y ≤ 45 x + y ≤ 80
And total number of reservations cannot exceed 80:
x + y ≤ 80.
Using the equation, y=5x²−17x −12, determine whether the parabola opens upward or downward.
Answer:
opens upwards
Step-by-step explanation:
given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
• if a > 0 then parabola opens upwards
• if a < 0 then parabola opens downwards
given
y = 5x² - 17x - 12
with a = 5 > 0
then parabola opens upward

What is consistent Equation?
A linear or nonlinear system of equations is called consistent if there is at least one set of values for the unknowns that satisfies each equation in the system—that is, when substituted into each of the equations, they make each equation hold true as an identity.
Let x represents the number of one-bedroom houses and y represents the number of two bedroom houses.
According to Question,
Total number of houses is 12 i.e. x + y = 12..........(i)
Total we have 88 windows in which 6 windows can be use in one bedroom house and 9 windows can be used in two bedroom house so,
6x + 9y = 88 ..................(ii)
From Equation (i) and (ii), we get
x = 7 and y = 5

Answer the following questions.
(a)
What is the total cost of transporting 11 tons?
$?
(b)
If the total cost is $11,750, how many tons is the company transporting?
? tons
Answer:
(a) C = $9250
(b) n = 21 tons
Step-by-step explanation:
(a) 11 tons being transported, so n = 11.
∴ C = 250 (11) + 650
C = $9250
(b) C = $11,750
∴ 11750 = 250n + 6500
250n = 5250

a) P(girl) = 1/3, which means that 1/3 = 33% of the time, the first batter will be a girl.
b) P(boy) = 2/3, which means that 2/3 = 67% of the time, the first batter will be a boy.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
