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

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
What two numbers multiply to +34 and add to -19
Answer:
17 * 2 = 34
-10 + (-9) = -19 or -29 + 10 = -19
Step-by-step explanation:
For the first question, divide 34 * 2 and you get 17, DOUBLE CHECK YOUR ANSWER!
17*2 = 34 ✔
For the second, mess around with a few numbers add +10 and -29, COUNT DOWN from 10 and -29.
since + + + = + then - + - = -
if 10+9=19 then do the same with -
-10 + (-9) =-19

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
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

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 complete question is given below.

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
Simplify the expression.

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°
Consider a person from birth to age 18 and the height of that person each of the years between birth and age 18. Which best describes the variables of age and height?
no correlation
positive correlation
negative correlation
Answer:
Seems to be no correlation at all.
Answer:
anges between -1 and +1 and quantifies the direction and strength of the linear association between the two variables. The correlation between two variables can be positive (i.e., higher levels of one variable are associated with higher levels of the other) or negative (i.e., higher levels of one variable are associated with lower levels of the other).
The sign of the correlation coefficient indicates the direction of the association. The magnitude of the correlation coefficient indicates the strength of the association.
For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables.
It is important to note that there may be a non-linear association between two continuous variables, but computation of a correlation coefficient does not detect this. Therefore, it is always important to evaluate the data carefully before computing a correlation coefficient. Graphical displays are particularly useful to explore associations between variables.
The figure below shows four hypothetical scenarios in which one continuous variable is plotted along the X-axis and the other along the Y-axis.
