For the requirements of a report Suzy has to write for school, she has a choice of wide-rule or narrow-rule paper and three different pen colors in which to write the report. How many different possibilities does Suzy have to write the report? Enter a numerical answer only.
Answer:
6
Step-by-step explanation:
You first have to choose from Wide and Narrow.
Let's call them W and N
Then you have to choose 3 different pen colors.
Let call them, 1, 2, 3
So There are two choices from W and N.
Then we pick the number: 1, 2, 3.
so If you pick W, you will have 3 choices. Same for N.
So in total: 6 choices.
W= 3 choices, W1, W2, W3
N= 3 choices, N1, N2, N3
so 6 in total.

20x=-58-2y
17x=-49-2y
Answer:
20x = -58 - 2y( Ans~ x= -29/11)
17x = -49 - 2y (Ans~ x = -49/19)
Step-by-step explanation:
(1) 20x = -58 2x
20x + 2x = -58
22x = -58
x = -29/11
(2) 17x = -49 - 2x
17x + 2x = -49
19x = -49
x = -49/19
U WELCOME!!
Answer:
y=1
x=-3
Step-by-step explanation:
20x=-58-2y
20x/20=(-58-2y)/20
x=(-58-2y)/20
17x=-49-2y
17x/17=(-49-2y)/17
x=(-49-2y)/17
(-58-2y)/20=(-49-2y)/17
17(-58-2y)=20(-49-2y)
-986-34y=-980-40y
add 40y to both sides
6y-986=-980
add 986 to both sides
6y=6
divide both sides by 6
y=1
substitute
20x=-58-2(1)
20x=-60
x=-3
Proof: (substituting x & y values in original equations)
20(-3)=-58-2(1)
-60=-60
17(-3)=-49-2(1)
-51=-51
Solve for b.
(b-7)m=r
(b-7)m=r
Use the distributive property to multiply b-7 by m.
bm-7m=r
Add 7m to both sides.
bm=r+7m
The equation is in standard form.
mb=7m+r
Divide both sides by m.
mb/m = 7m+r/m
Dividing by m undoes the multiplication by m.
b= 7m+r/m
Divide r+7m by m.
b= r/m+7

Step-by-step explanation:
Given f(x) = x^2 + x + 1 and given g(x) = x^2 - 9, find (f+g)(x).
========================================
Work Shown:
(f + g)(x) = f(x) + g(x)
(f + g)(x) = x^2+x+1 + g(x) ............... plug in f(x) = x^2+x+1
(f + g)(x) = x^2+x+1 + x^2-9 ........... plug in g(x) = x^2-9
(f + g)(x) = (x^2+x^2)+x+(1-9)
(f + g)(x) = 2x^2+x-8
Solve for X
-8 - x = x - 4x
Answer:
−8−x=x−4x
Step 1: Simplify both sides of the equation.
−8−x=x−4x
−8+−x=x+−4x
−x−8=(x+−4x)(Combine Like Terms)
−x−8=−3x
−x−8=−3x
Step 2: Add 3x to both sides.
−x−8+3x=−3x+3x
2x−8=0
Step 3: Add 8 to both sides.
2x−8+8=0+8
2x=8
Step 4: Divide both sides by 2.
2x

12. Suppose a reward for a CS follows a probabilistic schedule. If the probability of receiving the reward increases then: a) firing will increase for CS and increase for US b) firing will increase for CS and decrease for US c) firing will decrease for CS and decrease for US d) firing will decrease for CS and increase for US e) none of the above; firing will remain unchanged for CS and US
Answer:
d) firing will decrease for CS and increase for US
Step-by-step explanation:
The is the answer going by the probabilistic nature of the schedule. That is, as the probability of relieving reward increase has a direct effect on the CS leading to its decrease as well as a proportional increase for US. On the other hand, a decrease of probability of receiving reward will have an opposite effects on the schedule.

y = 8x - 6
2x - 4y = 24
9514 1404 393
Answer:
(x, y) = (0, -6)
Step-by-step explanation:
Substitute for y in the second equation:
2x -4(8x -6) = 24
2x -32x +24 = 24
-30x = 0
x = 0
y = 8·0 -6 = -6
The solution is (x, y) = (0, -6).

The length of the third side of the right angle triangle is 14.86
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the triangle be ΔABC
Now , the triangle ABC is a right angle triangle
And the value of the base of the triangle BC = 10
The value of the height of the triangle AB = 11
Now , the hypotenuse of the triangle AC is calculated from Pythagoras Theorem
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Substituting the values in the equation , we get
AC² = AB² + BC²
AC² = 11² + 10²
AC² = 121 + 100
AC² = 221
Taking square roots on both sides of the equation , we get
AC = 14.86
Therefore , the value of AC is 14.86
Hence , The length of the hypotenuse of the right angle triangle is 14.86
