2(a+3)/b
Let a=-3 and b=2
2(-3+3) / 2
2(0)/2
0/2
0
Answer:
0
Step-by-step explanation:
We are given the expression:
2(a+3)/b
We know that a= -3 and b=2. Therefore, we can substitute -3 in for a and 2 in for b.
2(-3+3)/2
Now, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition, Subtraction.
Solve inside the parentheses first. Add -3 and 3.
2(0)/2
Multiply 2 and 0.
0/2
Divide 0 by 2

AWARDING MAX POINTS
Answers
Answer:
The length of EB is found 15
Step-by-step explanation:
As the diagram of the circle is not given in the question, I've found the diagram of the same question from internet and attached below. So that we can have a better understanding)
We can see in the diagram the chord AB and chord CD intersect each other at point E.
Each of the chord is divided into two segments.
According to the Intersecting Chords Theorem:
Products of the lengths of line segments on each chord are equal
Which means that
(AE)(EB) = (CE)(ED)
Substitute the given values;
(4)(EB) = (10)(6)
4(EB) = 60
EB = 15

Step-by-step explanation:
The interior angles of triangle ABC measure 34°, 63°, and xº. The Interior angles of
triangle DEF measure yº, 63°, and 83º.
Which statement is true?
The triangles are similar because y=34 and there are three pairs of congruent
angles.
The triangles are similar because they each have an interior angles that
measures 63º.
The triangles are not similar because x does not equal y.
The triangles are not similar because y does not equal 34º.
Answers
Answer:
the triangles are similar because y=34 and there are three pairs of congruent angles
Step-by-step explanation:
this is correct because all of the angles in a triangle add up to 180, so if y = 34 then 34 + 63 + 83 = 180
this also means x is equal to 83 which means both triangles share all of the same angle measures
Which is the equation of a line that has a slope of One-half and passes through point (2, –3)?
Answers
Answer: y=1/2x-4
Step-by-step explanation:
Since we are given the slope, we can use the slope-intercept form to find the y-intercept.
y=1/2x+b
-3=1/2(2)+b
-3=1+b
b=-4
Now that we know our y-intercept, we can fill in our slope-intercept equation.
y=1/2x-4

The average rate of change is [tex]\frac{f(b)-f(a)}{b-a}[/tex]. All we have to do is to plug in our values.
a=-2

f(b)=f(-1)=(-1)²+10=11
f(a)=f(-2)=(-2)²+10=14

Answers
Answer:
6
Step-by-step explanation:
Given the system of equations:
y = 6x-b (eq. 1)
-3x+1/2y = -3 (eq. 2)
We can rewrite eq. 1 as follows:
-6x + y = -b
Dividing by 2:
(-6x + y)/2 = -b/2
-6x/2 + y/2 = -b/2
-3x + 1/2y = -b/2
The system of equations will have infinite number of solutions if both equations are equal. Therefore:
-b/2 = -3
b= -3*(-2)
b = 6

B. 5.81
Step-by-step explanation:
So to get this answer, you'd first find how much square inches are on the cheese. We know its 9/10 of the pizza and the pizza is 215 square inches. To find out what is 9/10 of the pizza you'd multiply 215 by 9 then divide by 10. That'd leave you with 193.5 then you multiply that by the cost $0.03 then get 5.805 which rounds up to 5.81.

What angle measure is complementary to a 65 angle?
Answers
Answer:
x = 25
Step-by-step explanation:
Complementary angles add to 90 degrees
x+65 = 90
Subtract 65 from each side
x = 90-65
x = 25
The Definition of Complementary Angles states that if two angles are
complementary, then the sum of their measures is 90°.
To find the complement of an angle, we take 90 degrees minus the
measure of the angle which in this case 90° - 65° or 25°.
So the complement of the 65° angle measures 25°.
help please i did a problem like this and got it wrong i honestly think im confusing the closed and open dots. can some one just please help
Answers
Answer:
It should be a "closed" dot facing the left side (towards the negative numbers)
Step-by-step explanation:
The graph will be a line segment with endpoints -1 and 1. Both endpoints are closed dots. This is to indicate we include the endpoints as part of the solution set. Everything between the endpoints is shaded in.
The answer in interval notation is [-1, 1]. The square brackets tell the reader to include the endpoints. This describes the interval from -1 to 1, inclusive of the endpoints.
How do we know to include the endpoints or not? By looking at the "or equal to" portion. If that is present, then we include the endpoint; otherwise, we exclude.

1) Subtract 6 from both sides.
2) Divide by 5.25 on both sides to get x on its own.
[tex]5.25x+6=74.25\\5.25x+6-6=74.25-6\\5.25x=68.25\\\frac{5.25x}{5.25} = \frac{68.25}{5.25} \\x=13[/tex]

State the Domain and Range for this equation in the context of the problem scenario?
Answers
Answer:
x-intercept: x=24
DOMAIN: (0,24) where x∈Natural Numbers
RANGE: (0,12) where y∈Natural Numbers
Step-by-step explanation:
Remain money = y
Number of games = x
Given function:
[tex]y=12-0.5x\\[/tex]
x-intercept:x-intecept is the value of x where y becomes zero.
Substitute y=0 in the given equation:
[tex]0=12-0.5x\\0.5x=12\\x=\frac{12}{0.5}\\x=24[/tex]
Domain:Domain is a set of all possible values of x.
x= No. of games (So x cannot be negative)
y= Remain Amount (So y cannot be negative)
So the minimum value of x is 0 because x cannot be negative.
Maximum value of x is the value for which y doesn't become negative. For any value of x>24, y <0 which is not possible.
So maximum value of x is 24
DOMAIN: (0,24) where x∈Natural Numbers
Range:
Range is a set of all outcomes of y for all possible values of x.
For x=0 , y =12
for x=24 , y = 0
So
RANGE: (0,12) where y∈Natural Numbers

Answer: 1. she will raise $6 per week. 2) $600
Step-by-step explanation:
30/5 = 6 she will raised $6 per week.
so her total donation will be $200 because she is raising $30 more.
Now if her father matches the her total then she will now have $400 because her father doubles it.
Now her mother will also add the same amount which will make it $600
because $400 + $200 = $600.

O (4,7)
O (4.-7)
Answers
Answer:
(4, 7) (third answer choice)
Step-by-step explanation:
In the system
y = x + 3
3x + y = 19
the first equation already gives y in terms of x. Thus we can substitute x + 3 for y in the second equation:
3x + (x + 3) = 19, which simplifies to:
4x = 16, yielding x = 4. Substituting 4 for x in the first equation, we get:
y = (4) + 3 = 7.
Thus, the solution is (4, 7) (third answer choice).
