Answer: x + 6y - 2 = 0 ; - x + 4y + 4 = 0
Step-by-step explanation:
General form of equation :
x / a + y/b = 1
With x intercept = a ; y intercept = b
From the question :
X intercept = 2 ; y intercept = 1/3
x / 2 + y/ 1/3 = 1
x /2 + 3y / 1 = 1
Multiply through by 2
x + 6y = 2 ; x + 6y - 2 = 0
2)
x intercept = 4
y intercept = - 1
x / 4 + y/ - 1 = 1
(-x + 4y) / - 4 = 1
-x + 4y = - 4 ; - x + 4y + 4 = 0

Answer:
35.25p + 7.5r = 185
Step-by-step explanation:
Gallons of paint: p
Rollers: r
35.25p + 7.5r = 185
Amanda increased the amount of protein she eats every day from 48g to 54g. By what percentage did Amanda increase the amount of protein she eats?
Answer:
Explanation:
The formula for calculating the percent change is:
p=N−OO⋅100
Where:
p is the percent change - what we are looking for
N is the New Value - 54g for this problem
O is the Old Value - 48g for this problem
Substituting and calculating p gives:
p=54−4848⋅100
p=648⋅100
p=60048
p=12.5
Please MARK AS BRAINLIEST
Answer:
12.5%! :)
Step-by-step explanation:
The formula for calculating the percent change is:
p=N−OO⋅100
Where:
p is the percent change - what we are looking for
N is the New Value - 54g for this problem
O is the Old Value - 48g for this problem
Substituting and calculating p gives:

Laura and Kennedy are at softball practice. Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second. Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second.
Answer:
C
Step-by-step explanation:
The system of equations [tex]y = -16x^2+60x+3\\y=-16x^+55x+2.5[/tex] models the projectile motion of the two balls. option C is correct.
Laura and Kennedy are at softball practice. Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second. Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second. The projectile equations is to be determined.
What is the projectile motion?Projectile motion is the movement of an entity projected into the space. After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory.
Projectile equation = vertical motion + horizontal motion + intercept.
Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second.
y = gx²/2 + v*x + 3
y = -32/2 * x² + 60x + 3
y = -16x² + 60x + 3
Similarly, Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second.
y = -16x² + 55x + 2.5
Thus, the system of equations [tex]y = -16x^2+60x+3\\y=-16x^+55x+2.5[/tex] models the projectile motion of the two balls. option C is correct.

) A fraction becomes 4
5
if 1 is added to both numerator and denominator.
If, however, 5 is subtracted from both numerator and denominator, the fraction becomes 1by2
.
Answer:
?????????????????????????
Answer:
original fraction = [tex]\frac{7}{9}[/tex]
Step-by-step explanation:
let x be the numerator and y be the denominator of the original fraction, then
[tex]\frac{x+1}{y+1}[/tex] = [tex]\frac{4}{5}[/tex] ( cross- multiply )
5(x + 1) = 4(y + 1) ← distribute parenthesis on both sides
5x + 5 = 4y + 4 ( subtract 4y from both sides )
5x - 4y + 5 = 4 ( subtract 5 from both sides )
5x - 4y = - 1 → (1)
Also
[tex]\frac{x-5}{y-5}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2(x - 5) = y - 5
2x - 10 = y - 5 ( subtract y from both sides )
2x - y - 10 = - 5 ( add 10 to both sides )
2x - y = 5 → (2)
Solve the 2 equations simultaneously for x and y
Multiply (2) by - 4
- 8x + 4y = - 20 → (3)
Add (1) and (3) term by term to eliminate y , that is
- 3x = - 21 ( divide both sides by - 3 )
x = 7
Substitute x = 7 into either of the 2 equations and solve for y
Substituting into (1)
5(7) - 4y = - 1
35 - 4y = - 1 ( subtract 35 from both sides )
- 4y = - 36 ( divide both sides by - 4 )
y = 9
Thus the original fraction = [tex]\frac{7}{9}[/tex]

18X - 15+13X - 11+4x + 1=180
what’s x?
Answer: x equals forty one over five
Step-by-step explanation: Add the numbers 18x-15+3x-11+4x+1=180 18x-25+3x+4x=180 then you combine like terms and you get, 18x-25+3x+4x=180 25x-25=180 then you add 5 to both sides of the equation 25x-25=180. 25x-25+25=180+25 then you simplify then you add the numbers 25x=205 then you divide both sides of the equation by the same term 25x=205 25x/25 = 205/25 then you simplify, you cancel terms that are in both the numerator and denominator then you divide the numbers and you get, x equals forty one over five.
In 2000 jonesville had a population of 15,000. In 2001 the population was 16,250 and in 2002 the population was 17,500 in the population grew at the same constant rate each year which model describes the population growth for n years after 2000?
Answer:
15000+1250x
Step-by-step explanation:
Since the initial population is 15,000, we want to know how many people are going to Jonesville each year. Assuming that in 2001 and in 2002, each year adds 1,250 people and that it is constant. The equation is 15000+1250x in which 15,000 represents the initial number and 1250 is the amount of people added each year followed by x which is the number in years.

What is the mapping notation that will transform triangle ABC to triangle A'B'C'?
A.(x + 2,y - 14)
B.(x - 4, y - 8)
C.(y, -x)
D.(-y, x)
Answer:
The transformation is (y,-x)
Step-by-step explanation:
To know the mapping notation, we need to know the coordinates of the image and the pre-image
For the pre-image, we have;
A(3,8)
B(6,8)
C(6,2)
For the image, we have
A’( 8,-3)
B’ (8,-6)
C’ (2,-6)
So let us try and get the transformation from the coordinates
We can see that this is;
(x,y) to (y,-x)
