Answer:
The points that were given are not on the graph of y=3x+2.
Step-by-step explanation:
The slope is 3 and the y-intercept is 2 so on the graph you rise three times from the point (0,0) to (0,3) then you run twice to the right so your first plot would be (2,3). After following the same process the next three plots would be (4,6),(6,9),&(8,12). So those plots that were given are incorrect. Remember y=mx+b
Mx is your slope to rise with and b is your y-intercept to run with.
Rise/run. I just put the important stuff in bold.

4w-41 = -7(w-2) Simplify your answer as much as possible.
Answer:
w = -13
Step-by-step explanation:
4w - 41 = 7(w-2)
Open the bracket
4w -41 = 7w -14
Collect like terms
4w - 7w = 41 - 14
-3w = 27.
Divide both side by -3
w = -9
Answer: w = 5
Step-by-step explanation:
4w-41=-7w+14
4w+7w=14+41
11w=55
W = 55/11
W = 5

Find the approximate area of the quadrilateral with the given coordinates A(0, 4), B(5, 2), C(3, -3) and D(-2, -1)
Answer:b
Step-by-step explanation:
The area of the quadrilateral with the given coordinates is 27 square units.
The coordinates of the quadrilateral are A(0, 4), B(5, 2), C(3, -3) and D(-2, -1).
We need to find the area of the quadrilateral with the given coordinates.
What is the formula to find the area of the quadrilateral with coordinates?The formula to find the area of the quadrilateral with coordinates ( x₀, y₀ ), ( x₁, y₁ ), ( x₂, y₂ ), ( x₃, y₃ ) is (1/2) × ( x₀y₁ - x₁y₀ + x₁y₂ - x₂y₁ + x₂y₃ - x₃y₂ + x₃y₀ - x₀y₃ ).
Now, Area=1/2×(0×2-5×4+5×(-3)-3×2+3×(-1)-(-2)×(-3)+(-2)×4-0×(-1))
=1/2×|(-20-15-6-3-6-8)|=27 square units.
Therefore, the area of the quadrilateral with the given coordinates is 27 square units.

Use the diagram to the right.
If AD = 17 and AC = 2y - 6, find the value of y. Then find AC
and DC.
Step-by-step explanation:
if AD =17,then Dc is also 17 because from the diagram,it is given that AD=DC.
And because AD and DC are equal,it means AC = AD +DC,therefore AC = 17+17,AC =34
AC=2y-6
therefore
34=2y-6
28=2y and y=14

Which number is divisible by 10? 41 128 104 120
Consider f(x)=4x and g(x) = square root of x^2-1 and h(x)= square root of 16x-1
f(x) = 4x
g(x) =
[tex] \sqrt{x^{2} \: - \: 1 } [/tex]
h(x) =
[tex] \sqrt{16x \: - \: 1} [/tex]
We want to check if h(x) = g(f(x))
So g(f(x)) =
[tex] \sqrt{(4x) {}^{2} - \: 1} [/tex]
Simplified;
g(f(x)) =
[tex] \sqrt{16x {}^{2} \: - \: 1 } [/tex]
But h(x) =
[tex] \sqrt{16x \: - \: 1} [/tex]
Hence g(f(x)) is not equal to h(x)

X to the 3rd power= 64/343
Answer:
x = 4/7
Step-by-step explanation:
x^3 = 64/ 343 // - 64/ 343
x^3 - ( 64/ 343 ) = 0
x^3 - 64 / 343 = 0
1*x^3 = 64/ 343 // : 1
x^3 = 64/ 343
x^3 = 64/ 343 // ^ 1/3
x = 4/ 7

When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with a mass of 4 kg, the acceleration of the object is 7 m/s 2. When the same force acts upon another object, it’s acceleration is 2 m/s. What is the mass of this object
First:
F=m.a
=4*7
=28N
Second:
F=m.a
28=m.2. (force is constant,so F=28N)
28/2=m
m=14kg.
Answer:
First:
F=m.a
=4*7
=28N
Second:
F=m.a
28=m.2. (force is constant,so F=28N)

Solve for the value of r.
(7r-5)
(6r+4)°
Answer:
r = 9
Step-by-step explanation:
These are vertical angles, therefore, the measurements is the same. Set the two measurements equal to each other:
7r - 5 = 6r + 4
Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 5 and subtract 6r from both sides of the equation:
7r (-6r) - 5 (+5) = 6r (-6r) + 4 (+5)
7r - 6r = 4 + 5
Simplify:
7r - 6r = 4 + 5
r = 9
9 is your value for r.
