help please! pretty easy i just dont remember how to do it
Answer:
Step-by-step explanation:
the disc. is the part under the root in the general formula
which is equal b^2 - 4 x a x c
in this equation a = 1 " coefficient of x^2"
b = 0 "coefficient of x which isn't found here "
c = 12 " the absolute "
[tex]0^{2} - 4[/tex]×[tex]1[/tex]×[tex]12[/tex] = -4×12 = something i don't have a calculator
but it will be negative so the roots will be complex and unreal

Evaluate the expression x/2+5x−7 when x=2 .
Answer:
The Answer is 4
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
So you inscert x as 2 which will give you
2/2+5(2)−7 (punch that in the calculator)
= 4
or if you need to expand your answer you can write it down like this
= 2/2+5(2)−7
= 1+10-7
= 11-7
= 4

Solve the for the variable. SHOW ALL WORK/EXPLAIN EVERY STEP!!!
2(x-2)-5=3-2x+6
Answer:
x=9/2
Step-by-step explanation:
First distribute 2
2x-4-5=3-2x+6
Add the like terms on the left side -4-5=-9
2x-9=3-2x+6
Do this with the right side 3+6=9
2x-9=-2x+9
Add 9 from the left side to the right side
2x=-2x+18
Then add 2x from the right side to the left side
4x=18
Divide 4 from both sides
x=18/4 or 9/2
Answer:
9/2
Step-by-step explanation:
2x-4-5= 3-2x+6 distribute 2 through the parentheses
2x-4-5=9-2x add the numbers
2x-9=9-2x calculate the difference
2x+2x-9= 9 move variable to left side and change sign
2x+2x= 9+9 move constant to right side and change sign
4x= 18 collect like terms
x=9/2 divide both sides by 4

. A honeybee leaves the hive, traveling at a speed of 4 mph and returns 1 hour later. What was the distance traveled and the displacement of the honeybee in miles?
Answer:
4milesStep-by-step explanation:
Step one:
given
speed, v= 4mph
time taken t=1 hour
The velocity is defined and the rate of change of displacement
Required:
Distance traveled
we know that the expression relating distance, velocity and time is
velocity= distance/time
distance= velocity* time
substitute we have
Distance=4*1
Distance= 4miles
The distance traveled and the displacement of the honeybee in miles 4miles
Ariana borrows $200 on a 6-year loan.She is charged 5% simple interest per year.How much interest is she charged for 6 years?What is the total amount she has to pay back? PLS HELP
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Principal (P)= $200
Interst rate (r)= 0.05
Time (t)= 6
First, we need to calculate the total interest using the following formula:
I= P*r*t
I= 200*0.05*6
I= $60
Now, the total debt:
Total debt= P +I
Total debt= 200 + 60
Total debt= $260
Evaluate: -30 ÷ 2

Angle ABC has a measure of 125° Angle ABC is rotated 75° about point B to create angle A'B'C'. What is the measure, in degrees, of angle A'B'C
Answer:
m∠A'B'C' is 125°
Step-by-step explanation:
The given parameters are;
The measure of ∠ABC = 125°
The form of transformation applied to ∠ABC = 75° rotation about the point B
Given that a rotation of a geometric figure is a form of rigid transformation, the distance between the coordinates of the points in the preimage are equal to the distance between the coordinates of the points on the image;
Therefore, the angle formed by the ray AB and CB and the angle formed by the ray A'B' and C'B' are equal
From which we have;
m∠ABC = m∠A'B'C' = 125°
what is 5y^3 without an exponent
Tell me the ordered pair for the y intercept
Answer:
(0, 3)
Step-by-step explanation:
The y-intercept is point on the y-axis that the line passes through.
You can see the line passes through 3 on the y-axis.
On the y-axis, every point has a 0 for the x-coordinate.
The ordered pair for the point that is 3 on the y-axis is (0, 3).
what is x and y:
y= 2x-11
y=x-3
