Which statements could be represented by the expression 2(a + b)? Choose ALL correct answers.
*
2 points
The quantity a plus b doubled
The sum of a and b plus 2
Twice the quantity of a and b
The difference of a and b times 2
PLS HELP ASAP
Answer: The quantity a plus b doubled
Twice the quantity of a and b
Step-by-step explanation: You're multiplying the sum of a and b by two. Multiplying by two and doubling is the same. Twice is a synonym for two times. there is no addition happening that involves 2 and there is no subtraction with a and b so the second and fourth choice are eliminated.
Find the rate of change between
(-1,-4)
(3,1)
Slope formula - [tex]\frac{y2-}{x2-} \frac{y1}{x1}[/tex]
First coordinate pair - (-1, -4)
Second coordinate pair - (3, 1)
Coordinate format - (x, y)
y2=1, y1=-4
x2=3, x1=-1
[tex]\frac{1-}{3-} \frac{(-4)}{(-1)} =\frac{5}{4}[/tex]
Hope this is what your looking for :)
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality

slope = -1
Find angle 1
(5x+6)° and (7x-18)°
Answer:
Step-by-step explanation:
<1 is the supplement of 5x + 5. You have to assume that the almost horizontal lines are parallel. In addition, two angles on the same side of a transversal across two parallel lines and are interior angles are supplementary.
5x + 6 + 7x - 18 = 180 Add like terms
12x - 12 = 180 Add 12 to both sides
12x = 180 + 12
12x = 192 Divide by 12
x = 192 /12
x = 6
====================
5x + 6 = 5*12 + 6
5x + 6 = 60 + 6
5x + 6 = 66
<1 + 66 = 180
<1 = 180 - 66
<1 = 114
Gina has a $50 gift card to a bagel shop. Each Friday, she purchases breakfast for $6. She created a graph to represent the amount of money on her gift card each week. Does Gina's graph represent the situation? Why or why not?
Math item stem image
CLEAR CHECK
Yes, because she starts with $50 on her gift card.
No, because the amount of money on her gift card should decrease each week.
Yes, because the amount of money that she spends increases each week.
No, because the graph should start at the origin.
Answer:
No, because the amount of money on her gift card should decrease each week.
Step-by-step explanation:
Well, the graph shows that the slope is increasing, if you got $50.00 and spend $6.00 each Friday, wouldn't that be decrease and not increase? This is why we eliminate the yes options. Lastly, of course, they should not start at the origin as they started at $50.00.

Who know these questions answers is
Answer:
4) The square root of 25 is rational
5) pi is irrational
Step-by-step explanation:
To know if the answer is rational or irrational, check to see if they can be turned into a fraction.
Answer:
4) [tex]\sqrt{25}[/tex]
5) [tex]\pi[/tex]
Step-by-step explanation:
4) [tex]\pi[/tex] is irrational.
[tex]\sqrt{2}[/tex] and [tex]\sqrt{3}[/tex] are also irrational.
[tex]\sqrt{25}[/tex] = 5. 5 is a whole number and thus is rational.
5) 16.5% = [tex]\frac{16.5}{100}[/tex]
0.0675 is a terminating decimal so it is rational.
8[tex]\frac{3}{4}[/tex] = 8.75 is also a terminating decimal so it is rational.

How do you graph this? ALSO I WILL GIVE BRAINLIEST ASWER TO FIRST PERSON TO ANSWER!!!!!!!!
Step-by-step explanation:
I have attached an image of the graph of this inequality from Desmos, a virtual graphing website to help answer your question.
However, to explain this graph, each and every x value less than or equal to 5 would be an appropriate solution to the inequality, thus all values less than or equal to 5 are shaded in.
Two communications companies offer calling plans. With Company X, it costs 30¢ to connect and
then 5e for each minute. With Company Y, it costs 20¢ to connect and then 4¢ for each minute. Write
and simplify an expression that represents how much more Company X charges, in cents, for n
minutes
Which of these expressions represents how much more Company X charges than Company Y?
OA. (30 + 4n) - (20+5n)
OB. 30n -5- 20n - 4
OC. (30n - 4) - (20n-5)
OD. (30 + 5n) - (20 + 4n)
The expression _ represents how much more Company X charges than Company Y.
(Simplify your answer.)
HELP
Answer:
D
Step-by-step explanation:
you can model the amount that each phone plan will cost after n minutes with these linear equations
company X: [tex]30 + 5n[/tex]
company Y: 20 + 4n
if you subtract the functions you can get the function for the
30 + 5n - ( 20 + 4n )
The Video Club charges a $100 membership fee and then charges $5 per movie. The Movie Market has a $25 membership fee and then charges $10 per movie. When will both clubs have the same cost? What is the cost?
Answer:
At 15 movies, both will cost $175
Step-by-step explanation:
Set it up algebraicly. Let x be the number of movies
100 + 5x = 25 + 10x
75 + 5x = 10x
75 = 5x
x = 15
Lets substitute x into one equation
100 + 5(15)
100+75
175

can someone help me don't show my math hw? ily and tysm.
Answer:
Step-by-step explanation:
16)
[tex]\frac{4}{10} , \frac{32}{72}\\\\\frac{4}{10} = \frac{32}{72}[/tex]
Cross multiply,
4 * 72 = 32 * 10
288 ≠ 320
So, these are not in proportion.
17)
[tex]\frac{40}{25} = \frac{32}{20}[/tex]
Cross multiply,
40 * 20 = 32 * 25
800 = 800
So, these are in proportion.
18)
[tex]\frac{15}{45}=\frac{9}{c}[/tex]
Cross multiply,
15 * c = 9*45
c = [tex]\frac{9*45}{15}[/tex]
c = 9*3
c = 27
19)
[tex]\frac{16}{120} = \frac{v}{15}[/tex]
Cross multiply
16 * 15 = v * 120
[tex]\frac{16*15}{120} =[/tex] v
v = 2
