What is the y-intercept of 2x-y=10
Answers
Answer:
( 0, -10 )
Step-by-step explanation:
the y intercepts is ( 0, -10 ) as u can see in this pic
Answer:
(0, -10)Step-by-step explanation:
We need to convert the equation to slope-intrcept form y=mx+b, where b is the y-coordinate of Y-intercept point
2x - y = 10 {subtract 2x from both sides}
- y = -2x + 10 {divide both sides by (-1)}
y = 2x - 10 ⇒ b = -10
Therefore y-intercept of the line is (0, -10)

The price of a man's shirt went from $15 to $20. What was the percent of increase of the price of the shirt? A. 25% A. , 25%, B. 3313% B. , 33 and 1 over 3 percent, C. 20% C. , 20%, D. None of these D. , none of these,
Answers
Answer: 33 1/3%
Step-by-step explanation:
Percentage increase of the shirt will be calculated as:
= Price Increase / Old price × 100%
Price Increase = $20 - $15 = $5
Old price = $15
Percent increase = Price Increase / Old price × 100%
= 5/15 × 100
= 1/3 × 100
= 33 1/3%
Answer:
it would be -25% because 15 is less than 20

What is the measure of the vertex angle
Answers
Answer:
Vertex angle = 124°
Step-by-step explanation:
m<BAC = m<BCA (base angles of isosceles ∆ are congruent)
7x + 1 = 5x + 9
Collect like terms
7x - 5x = -1 + 9
2x = 8
divide both sides by 2
x = 4
Vertex angle = 180 - ((7x + 1) + (5x + 9)) (sum of triangle)
Plug in the value of x
Vertex angle = 180 - ((7*4 + 1) + (5*4 + 9))
Vertex angle = 180 - (29 + 29)
Vertex angle = 124°
Sonya plans to spend at least 15$ on berries to make pies. Strawberries are on sale for 3$ per pint, and blueberries are on sale for 1$ per pint. SHe plans to buy at least 8 pints of berries.
Which system of inequalities can be used to determine the number of pints of strawberries, x, and the number of pints of blueberries, y, that Sonya should buy.
A=(3x+y≥15)
(x+y≥8)
B=(15≥3x+y)
(8≥x+y)
c=(15≥3x+y)
(x+y≥8)
D=(3x+y≥15)
(8≥x+y)
Answers
Answer:
B)
15 ≥ 3x + y
8 ≥ x + y
Step-by-step explanation:
Strawberries= 3x
Blueberries= y
At least symbol= ≥
15 ≥ 3x + y (Plans to spend AT LEAST $15 so this has to be 15 ≥)
8 ≥ x + y (Plans to spend AT LEAST 8 pints so this has to be 8 ≥)
The required, system of inequalities can be used to determine the number of pints of strawberries are 3x + y ≥ 15 and x + y ≥ 8. Option A is correct.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Since Sonya plans to spend at least $15 on berries and strawberries are on sale for $3 per pint, the cost of buying x pints of strawberries would be 3x dollars. Similarly, the cost of buying y pints of blueberries would be y dollars since they are on sale for $1 per pint. Therefore, we have:
3x + y ≥ 15 (Sonya plans to spend at least $15)
x + y ≥ 8 (Sonya plans to buy at least 8 pints of berries)
So the system of inequalities that can be used to determine the number of pints of strawberries, x, and the number of pints of blueberries, y, that Sonya should buy is:
A) 3x + y ≥ 15
x + y ≥ 8
So, option A is the correct answer.

You plan to go snowboarding this weekend in Pennsylvania. The resort charges $15.75 per hour in addition to a $25 deposit to rent a snowboard. Write and solve a linear equation to find the total cost to rent the snowboard from 8:30 a.m. to 12:30 p.m.
Answers
Answer:
$88 in total
Step-by-step explanation:
x = number of hours
y = total cost to rent the snowboard.
$25 is already guaranteed
25 + 15.75x = y
since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.
25+15.75(4) = y
88 = y

P is a rectangle length 40cm and width x cm the length of q is 25%more than the length of p
Answers
Answer:
the answer
the ratio x:y is 25:18
Step-by-step explanation:
we know that
the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18

The sum of ∠A and ∠B is 90°. ∠A and ∠B are complementary angles.
Step-by-step explanation:
∠A = 22.62 degrees
∠B = 67.38 degrees
The sum of ∠A and ∠B is 90°. ∠A and ∠B are complementary angles.
Which angles are complementary to each other?
2 right angles cannot complement each other2 obtuse angles cannot complement each other2 complementary angles are acute but vice versa is not possibleWhat is the formula for Complementary angles?
Complementary angles formulae. To find the complement on an angle, say ' x ', when expressed of radians, use the formula below: Complement of x rad = π/2 - x. For example, The complementary angle of 1/3π radian = π/2 - 1/3π = π/6 rad. To find the complement of an angle, say ' y 'when expressed in degrees, use the formula below: Complement of y ° = 90° - y .

x=3
———
-3*3+8y=1
5\4
Answer:
the x variable
Step-by-step explanation:
Given the 2 equations
3x + 6y = 27 → (1)
- 3x + 8y = 1 → (2)
Since the signs of the coefficients of x are opposite, then adding them will eliminate the x- term, that is
Add (1) and (2) term by term
0 + 14y = 28
14y = 28 ( divide both sides by 14 )
y = 2
Then substitute y = 2 into either equation for corresponding value of x

3 is the slope. Since it is y/x, then it is 9/3, which is simplified to 3/1.
Why?
You need two points to find slope I will use 5,19 and 2,10.
Slope is the difference of Y over the difference of x
19-10/5-2= 9/3 (simplify but divided each by 3)
3/1 so the slope is 3

A quantity with an initial value of 990 grows exponentially at a rate such that the quantity doubles every 4 years. What is the value of the quantity after 0.7 decades, to the nearest hundredth?
Answers
Answer:3329.95
Step-by-step explanation:
The value of the quantity after 0.7 decades, to the nearest hundredth is 1157.37.
Given that, a quantity with an initial value of 990 grows exponentially at a rate such that the quantity doubles every 4 years.
What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
We know that, S.I=(P×T×R)/100
Amount after 4 years is 1980
So, 990= (990×4×R)/100
⇒ 39.6R=990
⇒ R=990/39.6
⇒ R=25%
Amount = [tex]a(1+r)^t[/tex]
= [tex]990(1+0.25)^{0.7}[/tex]
= 1157.37
Therefore, the value of the quantity after 0.7 decades, to the nearest hundredth is 1157.37.
