Answer:
The graph of y > mx, where m > 0, consists of a dashed line and a shaded half-plane. The line has a positive slope and passes through the origin. The shadow of the half plane is above the line. m<0 means slope is negative
b>0 means the line will intersect the y axis above 0. Since the slope is positive, the graph is increasing. So like stated above The boundary line is dashed, and everything above it is shaded.
Step-by-step explanation:

4 + d = 6; 2
I need help with this answer dose am
The value of d is 2.
We are provided with the following equation,
4 + d = 6
We are supposed to find the value of d in the above equation.
To solve the equation we need to apply basic mathematical operations. The steps that need to be followed to simply this equation are mentioned below,
4 + d = 6
To get the value of d we need to subtract 4 from both the sides of this equation. On substracting 4 from both the sides of this equation, we will get
4 + d - 4 = 6 - 4
⇒ d = 6 - 4
⇒ d = 2
Thus, the value of d in the equation 4 + d = 6 is 2.

complete the proof that
In the given image:∠TUX ≅ ∠UXY - Alternate angles
What are alternate angles?When two parallel lines are cut by a transversal, the resulting alternate interior angles or alternate exterior angles are congruent, according to the alternate angle theorem. To demonstrate: If a transversal cuts two parallel lines, the alternate interior angles are equal. When a transversal intersects two or more parallel lines at different points, alternate exterior angles are formed. The term exterior refers to something that is located on the outside. Alternate exterior angles are always located on opposite sides of the transversal and always lie outside two lines intersected by the transversal.So, in the given image:
∠TUX ≅ ∠UXY - Alternate anglesTherefore, in the given image:∠TUX ≅ ∠UXY - Alternate angles

the two shorter sides in a right triangle have the same length . the area of the right triangle is 7.36 square meters. what is the length of the hypotenuse
The length of the hypotenuse is 5.426 meter
Let the two shorter sides of the right angles triangle be denoted as x meters.
The formula for the area of right triangle is given as,
A = ab/2
Where, a and b are the length of the shorter sides of the triangle
Also we have been given the area of the triangle which is 7.36 sq. meter
Thus , A = 7.36
x^2/2 = 7.36
x^2 = 14.72
x = 3.84
Now according to the Pythagoras theorem,
H = √P^2 + B^2
Where, H = hypotenuse
P = perpendicular
B = base
Now putting the required values we get
H = √x^2 + x^2
= √2x^2
= x√2
= 5.426 meter
Hence the length of the hypotenuse is 5.426 meter

How to find the area of the figure shaded in yellow?The figure shaded in yellow can be decomposed in two simpler ones, a triangle of base of 4 units and height of 5 units, and a rectangle of 5 units by 7 units.
The area of the triangle is:
A = 4*5/2 = 10 square units
The area of the rectangle is:
A' = 5*7 = 35 square units.
Adding that we get:
A + A' = 10 square units + 35 square units = 45 square units.

If there are 180 grams of radioactive material with a half-life (decrease by half or 50%) of 1 hour, how much of the radioactive material will be left after 3 hours?
Answer:
After 3 hours there is left 22.5 grams of radioactive material.
Step-by-step explanation:
We can calculate the mass of radioactive material remaining after 3 hours, by using the decay equation:
[tex]N_{t} = N_{0}*e^{-\lambda t}[/tex] (1)
Where:
[tex]N_{0}[/tex]: is the initial mass = 180 g
[tex]N_{t}[/tex]: is the remaining mass after time t
λ: is the decay constant
The decay constant is given by:
[tex] \lambda = \frac{ln(2)}{t_{1/2}} [/tex]
Where [tex]t_{1/2}[/tex] = 1 h.
By entering λ into equation (1) we hve:
[tex] N_{t} = N_{0}*e^{-\frac{ln(2)}{t_{1/2}} t} [/tex]
[tex] N_{t} = 180 g*e^{-\frac{ln(2)}{1 h} 3 h} = 22.5 g [/tex]
Therefore, after 3 hours there is left 22.5 grams of radioactive material.
