2(x + 5) = 3x + 1 I need help. Its saying that the answer is 9. When I typed in 9, it says explain how you got it.
Answer:
Step-by-step explanation:
just solve the equation
2x+10=3x+1
we will subtract 10 from one side and 3x from the other
2x-3x=-10+1
-x=-9 we will multiply by negative 1
x=9
you got the answer by solving the equation and find the value of x

Compare positive and negative slope for linear relationships. How are they the same? How are they different?
Answer:
Please check explanations
Step-by-step explanation:
Slopes are generally the ratio of rise(vertical difference) to fall (horizontal difference) for set of points lying on a straight line
Positive slopes show a positive relationship between the two things we are considering while a negative one shows otherwise
They are the same in the sense that they actually represent a constant change between the coordinates of the points in the relationship we are considering.
They are different in the sense that while one represents a positive change, whereby both axes move in the same direction ( rise at same rate, fall at same rate) , the second represent a relationship in which they move in opposite directions. While one falls, the other rises and while the other rises, the second one falls which indicates an opposing movement type between the two

A,b&c from a triangle where < bac= 90° Ab= 13.9 mm and ca= 8.8mm find the length of bc ?
Answer:
BC = 1 6.45
Step-by-step explanation:
The way it is written, BC is the hypotenuse
BC^2 = AB^2 + CA^2 Substitute the numbers for AB and CA
BC^2 = 13.9^2 + 8.8^2 Perform the squares
BC^2 = 193.21 + 77.44 Add the right side
BC^2 = 270.65 Take the square root of both sides
BC = 16.45

PLS HELP LOL!!! Isabella and Alice are standing some distance apart on the same side of a building 50 meters tall. From where Isabella stands, the angle of elevation of the top of the building is 30. From where Alice stands, the angle is 60. What is the distance between Isabella and Alice to the nearest tenth of a meter?
Answer:
57.7 m
Step-by-step explanation:
Since the distance between Isabella, the building and the angle form a right angled triangle with the height of the building = h = 50 m as the opposite side and x = distance between Isabella and the building = adjacent side and Ф = angle of elevation of the top of the building from Isabella = 30°.
So, from trigonometric ratios,
tanФ = h/x
and x = h/tanФ
= 50 m/tan30°
= 50/0.5774
= 86.6 m
Also, the distance between Alice, the building and the angle form a right angled triangle with the height of the building = h = 50 m as the opposite side and x' = distance between Alice and the building = adjacent side and Ф' = angle of elevation of the top of the building from Alice = 60°.
So, from trigonometric ratios,
tanФ' = h/x'
and x' = h/tanФ'
= 50 m/tan60°
= 50/1.7321
= 28.87 m
So, the distance between Isabella and Alice, x" = x - x'
= 86.6 m - 28.87 m
= 57.73 m
≅ 57.7 m

I think it's the first last one because proportional means it increases by the same each time so the last one fits in that category
Answer:
Number 1 is proportional, 2 is non proportional, 3 non proportional, 4 non proportional.
Step-by-step explanation:
You divide . 4÷1=4 , 8÷2=4, 12÷3=4, the unit rate MUST be the same !!!! And if there's 0 0, that doesn't count so like if your other 2 have the same unit rate it would still be proportional.

Saffron is very expensive spice. A shop selling saffron for $ 7.35 per gram. Write the formula for the cost (y), in dollars, of g grams of saffron
Answer:
y = 7.35g
Step-by-step explanation:
Given that:
Cost per gram of saffron = $7.35 per gram
The Cost (y) for g grams of saffron will be :
Cost = cost per gram * number of grams
Cost = $7.35 * g
Cost = 7.35g
Hence ;
y = 7.35g

Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What multiplicative rate of change should Hal use in his function?
0.02
0.98
1.02
1.98
Answer
The multiplicative rate of change that should be in Hal’s function = 49/50=0.98
=9.8×10⁻¹
Explanation
The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.
In this case the first term = 10000
The second term = 98% × 10000 = 9800.
The common ratio = 9800/10000=49/50
The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.
The equation of the exponential rate would be;
10,000ₓ0.98ⁿ.
where n is the number years.
Hope his helps! ;)

Ethan's football team scored a total of 35 separate times this season, with a mix of touchdowns and field
goals. Each touchdown is worth 7 points, and each field goal is worth 3 points. If the team scored a total of
193 points this season, how many touchdowns and field goals did they score?
9514 1404 393
Answer:
22 touchdowns13 field goalsStep-by-step explanation:
Let t represent the number of touchdowns scored. Then 35-t is the number of field goals, and the total score is ...
7t +3(35 -t) = 193
4t = 88 . . . . . . . . . . simplify, subtract 105
t = 22
35 -t = 13
The team scored 22 touchdowns and 13 field goals.
A chair normally priced at $75, is marked down to $41.25. What is the percentage decreased for the chair?
Answer:
The answer is B. I think.
Step-by-step explanation:
$75 divided by 10 is 7.5
7.5 = 10%
$41.25 divided by 7.5 or 10% = 5.5
5.5 x 10 = 55%
Sorry if this is not helpful.
The percentage decrease of the chair will be 55%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the chair normally priced at $75, is marked down to $41.25. The percentage decrease will be calculated below,
Percentage decrease = [ Final price / Normal price ] x 100
Percentage decrease = ( 41.25 / 75 ) x 100
Percentage decrease = 0.55 x 100
Percentage decrease = 55%
