Which graph represents the linear function y=-2x+3
Answers
The coordinates will be (0, 3) and (1.5, 0), and mark these points on the paper and make a straight line.
What is the linear system?
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The linear function is given below.
y = -2x + 3
Then the graph of the equation will be
Put x = 0, then the value of y will be
y = -2(0) + 3
y = 3
Put y = 0, then the value of x will be
2x = 3
x = 1.5
Then the coordinates will be (0, 3) and (1.5, 0).
Mark these points on the paper and make a straight line.
The graph is given below.

y = x^2+7x−4
y = −x−4
Answers
y = -x - 4
x² + 7x - 4 = -x - 4
+ x + x
x² + 8x - 4 = -4
+ 4 + 4
x² + 8x = 0
x(x) + x(8) = 0
x(x + 8) = 0
x = 0 or x + 8 = 0
- 8 - 8
x = -8
y = -x - 4
y = -0 - 4
y = 0 - 4
y = -4
(x, y) = (0, -4)
or
y = -x - 4
y = -(-8) - 4
y = 8 - 4
y = 4
(x, y) = (-8, 4)
The solutions are (0, -4) and (8, -4).
y=-x-4
We can solve this system of equation by equalization method.
x²+7x-4=-x-4
x²+7x+x-4+4=0
x²+8x=0
x(x+8)=0
we have two linear equations :
x=0 ⇒ x=0 ⇒ y=-x-4=-0-4=-4
(x+8)=0 ⇒ x=-8 ⇒ y=-x-4=-(-8)-4=8-4=4
We have two solutions:
solution₁: x=0; y=-4
solution₂: x=-8; y=4

Answer:
The squeegee passes by the other window washer in 3.9 seconds to the nearest tenth
Step-by-step explanation:
From the question,
The first person drops a squeegee from a height of 95 feet, to determine how long it takes the squeegee to pass by another person at a height of 20 feet, that is, we are to determine how long it will take the squeegee to travel a height distance of 95 feet - 20 feet
95 feet - 20 feet = 75 feet.
Hence, we are to determine how long it will take the squeegee to travel a height distance of 75 feet.
From one of the equations of motion due to free fall
h = ut + 1/2gt²
Where h is the height
u is the initial velocity
g is the acceleration due to gravity (Take g = 9.8 m/s²)
and t is the time
For the question,
h = 75 feet
u = 0 m/s ( Since the squeegee is dropped from rest)
Therefore
75 = 0(t) + 1/2(9.8)(t²)
75 = 4.9t²
∴ t² = 75/4.9
t² = 15.306
t =√15.306
t = 3.9 secs
Hence,
The squeegee passes by the other window washer in 3.9 seconds to the nearest tenth.
Final answer:
Using the kinematic equations for free fall, we find that it takes approximately 2.2 seconds for the squeegee to pass by the other window washer working at a height of 20 feet.
Explanation:
The question is related to the subject of physics and involves the free fall motion of an object under the influence of gravity. We can use the kinematic equations to solve for the time it takes for the squeegee to pass the window washer working at 20 feet.
The initial height h0 from which the squeegee was dropped is 95 feet, and the height h where the other window washer is located is 20 feet. Therefore, we are interested in the time it will take the squeegee to cover the distance d = h0 - h, which equals 75 feet.
Assuming acceleration due to gravity g is approximately 32.2 feet per second squared (in the downward direction), and initial velocity u is 0 since the squeegee is dropped, we can use the formula to find the time t.
Plugging in the values, we get:
- t = sqrt(4.6584)
- t ≈ 2.16 seconds
To the nearest tenth, it takes the squeegee approximately 2.2 seconds to pass by the other window washer.

Answer:
Mass of A = 5760 grams
Step-by-step explanation:
Surface area is given, so we can set-up a similarity equation to solve for k, proportionality constant. Here, we will relate both of them through k^2, because they are 2 dimensional (area). Thus
Surface Area of A = k^2 * Surface Area of B
28 = k^2 * 40.32
k^2 = 28/40.32
k^2 = 25/36
k = Sqrt (25/36)
k = 5/6
Now, we want to find mass (1 dimensional quantity), thus we can say:
Mass of A = k * Mass of B
Mass of A = (5/6) * (6912)
Mass of A = 5760 grams
Answer:
The mass of A is 4000g.
Step-by-step explanation:
First, divide 28 by 40. Then square root this to get the scale factor between them. (5 over 6). Mass is like volume in this case, so we need to cube 5/6 and then multiply that by 6912 to get the mass of A.
28÷40.32= 25/36
√25/36 =5/6
5/6³ x 6912= 4000g
