Answer:
A) 2x^2 -12x +13
B) terms {2x^2, -12x, 13}; coefficients {2, -12, 13}; constants {13}
Step-by-step explanation:
A) Using the distributive property, we get ...
-2x +3 +2x^2 -10x +10
= 2x^2 -12x +13
__
B) Terms: {2x^2, -12x, 13}
Factors: There are no overall factors. Each term has factors ...
2x^2 has factors {2, x, x}
-12x has factors {-1, 2, 2, 3, x}
13 has factors {1, 13} (it is prime)
Coefficients: {2, -12, 13} . . . see note below
Constants: {13}
_____
Additional comment
We have listed the prime factors of each term, any subset can be multiplied to be a factor of the term. For example, 2·3 = 6 is a factor of -12x.
Please note that some sources do not consider a constant (13) to be a coefficient. You will need to refer to your curriculum materials to see what your author says about that.

Write the equation of the line in slope intercept form that passes through the point (6,-2) and is parallel to the line y = -3x + 5.
Answer:
For a line to be parallel it must have the same slope. So the slope of the new equation is 6.
The slope intercept form is y=mx+b. And we have a point (3,-5). Plug in what we know....
-5=6(3)+b
Solve for b (the y-intercept)
b= -23
Therefore.... y=6x-23

Answer:
x=6
AD=x+18
=6+18
=24 (the final answer)
Answer:
x = 6
AD = 24
Step-by-step explanation:
To find the value of x and AD
We know that the opposite sides of parallelogram are equal
so
AD = BC
3x + 6 = x + 18
3x - x = 18 - 6
2x = 12
x = 12/2
x = 6
now we need to find AD
AD =3x + 6
instead of x we have to put 6
AD = 3 (6) +6
= 18 +6
= 24
AD = 24
Larry has three times as many pencils as Ben. Dejuan has four less than the number of pencils as Ben. Write the expression that would be the total number of pencils for all three of them.
Answer:
The total number of pencils for Larry, Ben and Dejuan is expressed as:
5B - 4
Step-by-step explanation:
Let B represent the number of pens Ben has.
》Ben = B
》Larry = 3 × B = 3B
》Dejuan = B - 4
∴ Total number of pencils for the three of them
= B + 3B + (B - 4)
= 5B - 4

If BD = BC , BD = 5x - 26, BC = 2x+1, and AC = 43, find AB
Answer:
BD is congruent to BC. BD=BC
BD = 5x – 26, BC = 2x + 1, and AC = 43
To find out , we need to find BC first . For that we have to find out x
WE know that BD=BC, using that we solve for x
Now we plug in 9 for x and find out BC
BC=2x+1
BC=2(9)+1
BC=19
We know AC= 43
AC=AB +AC
43=AB+19
subtract 19
AB = 24

Hello!
The slope equation is y = mx + b
mx is the slope and b is the yintercept.
4. y= -3x + 5
See where I put the slope and y intercept above?
Those are where the numbers go in that equation.
5. 3x + y = 5
The standard for equation is: Ax + by = c
y = -3x + 5
we need to make the equation look like the standard form equation.
y = -3x + 5
lets add 3x to both sides
The answer is 3x + y = 5
6. m = [tex]\frac{3}{2}[/tex]
We need to use this formula: [tex]m=\frac{y2-y1}{x2-x1} \\\\\\[/tex]
The points said are: (2, 5) and (4, 8)
[tex]m=\frac{8-5}{4-2}[/tex]
m = 3/2
M is the slope.

5. What is the area of quadrilateral DCFE?
(A) 14
(B) 18
(C) 24
(D) 32
(E 36
Answer:
m<DEF = 47°
Step-by-step explanation:
Given:
m(DEF) = 266°
Required:
m<DEF
Solution:
m<DCF = ½(m(DEF)) (Inscribed angle theorem)
Substitute
m<DCF = ½(266°)
m<DCF = 133°
Opposite angles in an inscribed quadrilateral are supplementary.
Therefore,
m<DEF = 180° - m<DCF
m<DEF = 180° - 133°
m<DEF = 47°
Choose the best description for the real number 35
Answer:
A) Irrational, because it is not a terminating or repeating decimal.
Step-by-step explanation:
Every time a square root results in a decimal, it will always never end, and never repeat. The square root of 35 qualifies for both of these qualities, therefore, making the answer (A). Hope this helps!

Answer:
(-2, 3)
Step-by-step explanation:
For x-4 you go left four places and y+6 go up 6 places
Answer:
(-2, 3)
Step-by-step explanation:
Point P has coordinates (2, -3).
The translation is (x - 4, y + 6) which means subtract 4 from the x-coordinate and add 6 to the y-coordinate.
The x-coordinate of point P is 2. Subtract 4 from it, you get -2.
The y-coordinate of point P is -3. Add 6 to it to get 3.
The coordinates of the translated point are (-2, 3).

5) Emily woks Monday through Friday at a rate of $16.12 per hour. She takes a 1-hour lunch break. If she
clocks in each day at 6:15 A.M. and leaves at 4:15 P.M., what is her total pay for the week? (show your
work)
Answer: $725.40
Step-by-step explanation:
6:15A.M. - 4:15 P.M. = 10 hours - 1 hour lunch = 9 hours/day
$16.12hr*9 hours = $145.08 per day
Monday thru Friday = 5 days
$145.08 * 5 = $725.40 per week
