6 and 9
Step-by-step explanation:
6 x 9 = 54
enter the value for x that makes the equation 4x-2+3x-7 true
Answer:
I think the answer is
[tex]x = \frac{9}{7} [/tex]
Step-by-step explanation:
Reason :
[tex]4x - 2 + 3x - 7 = 0 \\ collect \: like \: terms \\ 4x + 3x - 7 - 2 = 0 \\ 7x - 9 = 0 \\ 7x = 9 \\ x = \frac{9}{7} [/tex]
Therefore
[tex]x = \frac{9}{7} [/tex]
What is the axis of symmetry for y=8x2+2x−6?
Answer:
y=2( x - [tex]2^{2}[/tex])-2
Step-by-step explanation:
Use the vertex form, y=a(x - [tex]h^{2}[/tex])+k to determine the values of A,H,K
a=2
h=2
k= -2
Since the value of a is positive the parabola opens up.
Find the vertex (h,k)
(2, -2)
Find p the distance from the vertex to the focus.
[tex]\frac{1}{8}[/tex]
Find the focus
(2, -[tex]\frac{15}{8}[/tex])
Find the axis of symmetry by finding the line that passes through the vertex and the focus.
x=2

A = 50.24
To find the area of a circle we can use the following equation
[tex]A = r^2\pi \\A = 4^2\pi \\A = 16\pi \\\\A = 16*3.14\\A = 16*3.14\\\\A = 50.24[/tex]

The area of the parallelogram will be 98 square feet.
What is a parallelogram?It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.
Let h be the perpendicular distance between the parallel side and b be the length of the base of the rectangle.
Then the area of the parallelogram will be given as,
Area of parallelogram = b x h
The length of the base of the parallelogram is 14 feet, and the value of h is 7 feet.
Then the area of the parallelogram will be
Area pf parallelogram = 14 x 7
Area pf parallelogram = 98 square feet
Then the area of the parallelogram will be 98 square feet.

The Morris family just bought 8 crates of eggs, and each crate had 12 eggs. The family already had 9 eggs in their refrigerator. How many eggs do they have now?
They now have 30 eggs
I need a bf
Answer:
105 eggs
Step-by-step explanation:
Total eggs they bought = ( 8×12) = 96 eggs
They already had 9 eggs so adding 96 and 9 gives us 105 eggs in total
Express the function graphed on the axes below as a piecewise function
Answer:y = 2/3x +6 for x< -3
Step-by-step explanation:
The athletic department manager purchased a total of 52 footballs and soccer balls. Each football cost $23.53, and each soccer ball cost $19.86. If the manager spent a total of $1,120.80, how many soccer balls did the manager purchase?
Answer:
The manager purchased 28 soccer balls.
Step-by-step explanation:
Since the information states that the athletic department manager purchased a total of 52 balls, you can say that the result of adding up the number of footballs and soccer balls purchased is 52, which can be expressed as:
x+y=52, where:
x is the number of footballs purchased
y is the number of soccer balls purchased
Also, as the statement indicates the price of each type of ball and the total cost, you can say that adding up the results of multiplying the price of each ball for the quantity purchased is equal to the total amount spent, which is:
23.53x+19.86y=1,120.80
Now, you have 2 equations:
x+y=52 (1)
23.53x+19.86y=1,120.80 (2)
To be able to find the value of x and y, first you can isolate x in (1):
x=52-y (3)
Then, you can replace (3) in (2) and solve for y:
23.53(52-y)+19.86y=1,120.80
1,223.56-23.53y+19.86y=1,120.80
1,223.56-1,120.80=23.53y-19.86y
102.76=3.67y
y=102.76/3.67
y=28
Finally, you can replace the value of y in (3) to find the value of x:
x=52-28
y=24
According to this, the answer is that the manager purchased 28 soccer balls.

An event planner can set up 6 tables in 30 minutes. How many tables can the event planner set up in 4.5 hours?
First convert 4.5 hours to minutes
4.5 hours = 270 minutes
6:30 = ?:270
Divide 270 and 30
270/30 = 9
Then multiply 6 and 9
9*6 = 54
The event planner can set up 54 tables in 4.5 hours(270 minutes)
54 tables
ABCD is a cyclic quadrilateral (inscribed quadrilateral). Find the value of x and the measures of all the angles.
Answer:
Step-by-step explanation:
The "trick" to this problem is knowing that opposite sides of the box add up to 180°
Now that you know that maybe you can solve this?
180= 7x+2 + 6x-4
180 = 13x -2
182 = 13x
14 = x
find y now to find all the angles
180 = 2y + 4 +4y - 4
180 = 6y
30 = y
now solve the x expressions and the y expressions
7x+2
7(14)+2
98 + 2
D= 100°
6x-4
6(14)-4
84-4
B = 80°
2y + 4
2(30) + 4
60 + 4
A = 64°
4y-4
4(30)-4
120-4
C = 116°
Which equation models a proportional relationship with the unit rate of 3?

factor completely;
3x^2+4x-7
Answer:
(3x-7) (x+1)
Step-by-step explanation:
3x^2 - 4x - 7
First split the middle term
3x^2 + 3x - 7x - 7
Make into two separate expressions
(3x^2 + 3x) (-7x-7)
Take out what you can
3x (x+1) -7 (x+1)
Now you have your answers
(3x-7) (x+1)
The cost of electricity is obtained as follows: A fixed charge of $(a), rent of a meter $(b) and a charge of (c) cents for unit of electricity supplied Determine the total cost of using n units of electricity.
Answer:
$(a + b) + cn cent
Step-by-step explanation:
Given :
Fixed charge = $a
Rent of a meter = $b
Charge per unit of electricity = c cents
The total cost of using n units of electricity :
For n units of electricity ;
Fixed charge is paid once
Meter rent is paid once
The cost of electricity = (number of units * cost per unit) = (n * c) = nc cents
Total cost of n units of electricity :
$(a + b) + cn cent

Find the value of x and y that will make each quadrilateral a parallelogram.
Step-by-step explanation:
2x+5=3x-12
or, 2x-3x=5-12
or, -x= -7
i.e X=7
again
y+4=3x+2
or, y+4=3*7+2
or, y+4=21+2
or, y+4=23
or, y =23-4
i.e y = 19
hence, the value of X is 7 and y is 19
