Answer:
y=2x-1, answer choice D
Step-by-step explanation:
Start by calculating the slope. Slope = rise/run = (y2-y1)/(x2-x1).
You were given 2 points, (3,5) and (5,9).
Plug in those points to find the slope.
slope = (5-9)/(3-5)
slope = -4/-2
slope = 2
The slope intercept form is y=mx+b.
So we know the slope is 2.
That makes the equation y=2x+b. We need to find the intercept. So plug in one of the provided points and solve for b. Let's use (3,5).
y=2x+b
5=2*3+b
5=6+b
-1=b
So the y intercept (b) is -1.
That makes the equation y=2x-1.
You can check that the equation is correct by plugging in those points OR graphing it!

Salesman Scott received $2,792.79 for selling a property. If the gross commission was 6.5 % of the sale price, the listing salesman received 12% of the gross commission and Scott received 45% of the balance, how much did the property sell for?
Answers
Answer: The property sold for $5,870.41.
Step-by-step explanation:
Let x be the selling price of the property.
Then, gross commission = 6.5% of x = 0.065x
listing salesman received = 12% of ( 0.065x) = 0.12 (0.065x) = 0.0078 x
Balance = x - ( 0.065x) - (0.0078 x)
= (1+0.065-0.0078)x
= 1.0572x
Scott received = 45% of (1.0572x)
=0.45 (1.0572x)
= 0.47574x
Now, [tex]0.47574x=2,792.79[/tex]
[tex]\Rightarrow\ x=\dfrac{2792.79}{0.47574}\\\\\Rightarrow\ x=5870.41[/tex]
Hence, the property sold for $5,870.41.
What is the rate of change of the proportion y=9x

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The rate of change of the proportion y = 9x is 9.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
y = 4x +2 is an equation.
x + 2x + 3 = 4 is an equation.
We have,
y = 9x
The rate of change of this equation can be calculated by finding its differentiation.
Now,
y = 9x
Differentiating with respect to x we get,
dy/dx = 9dx/dx
dy/dx = 9
Thus,
The rate of change of the proportion y = 9x is 9.

Which costs more per issue, 18-issue subscription for $40.50 or a 12-issue subscription for $33.60?
Answers
Answer:
12-issue subscription
Step-by-step explanation:
18-issue sub = $40.50 ÷ 18 = $2.25/issue
12-issue sub = $33.60 ÷ 12 = $2.8/tissue
=> The 12-issue subscription costs more per issue (2.8 > 2.25)
Answer:
so you would divide the cost by the issue
the 18 issue is $2.25 per issue
the 12 issue is $2.80 per issue
the 12 issue costs more

[tex]\Delta MAT\cong \Delta MHT[/tex] and [tex]m\angle 2=82^\circ[/tex].
To find:
Whether [tex]m\angle 1=47^\circ[/tex] is possible or not.
Solution:
We have,
[tex]\Delta MAT\cong \Delta MHT[/tex]
[tex]\angle AMT\cong \angle HMT[/tex] (CPCTC)
[tex]m\angle 3=m\angle 8[/tex] ...(i)
And,
[tex]m\angle 1=m\angle 8[/tex] ...(ii) (Vertically opposite angles)
From (i) and (ii), we get
[tex]m\angle 1=m\angle 3[/tex] ...(iii)
Now,
[tex]m\angle 1+m\angle 2+m\angle 3=180^\circ[/tex] (Linear pair)
[tex]m\angle 1+82^\circ+m\angle 1=180^\circ[/tex] (Using (iii))
[tex]2m\angle 1=180^\circ-82^\circ[/tex]
[tex]2m\angle 1=98^\circ[/tex]
Divide both sides by 2.
[tex]m\angle 1=\dfrac{98^\circ}{2}[/tex]
[tex]m\angle 1=49^\circ[/tex]
The measure of angle 1 is 49 degrees so it cannot be equal to 47 degrees.
Therefore, the required answer is "no", the given statement [tex]m\angle 1=47^\circ[/tex] is not possible.

A weight of 6 lb stretches a spring a distance of 12 in. Find the constant k for the spring.
Answers
Answer:
Let F = the force (6 lbs) and x be the distance that the spring is stretched (12 inches).
F = kx
6 lb = k*(12 in.)
6/12 = k = 0.5 lb/in.
A weight of 6 lb stretches a spring a distance of 12 in. The constant k for the spring will be 0.5 lb/in.
How to obtain acceleration from force applied on an object?If the object is of mass m kg and force applied on it is of F N in the direction of motion, then the acceleration of that object is evaluated as:
a= F/m
Given; A weight of 6 lb stretches a spring a distance of 12 in.
Also,
Let F = the force and x be the distance that the spring is stretched
F = kx
6 lb = k*(12 in.)
6/12 = k = 0.5 lb/in.
Therefore, the constant k for the spring will be 0.5 lb/in.

Answers
7x + 8y = -12
Subtract 7x from both sides
8y = -7x - 12
Divide each side by 8

y = -7/8x - 3/2
So besides simplifying, if I’m doing this correctly, it should be correct.
