Answer:
y=3x-38
Step-by-step explanation:
We know that Tracy spent $38 in less than 3 times than what Daniel spent. Given this information we can put our eqaution together.
Y=3x-38
Hope this helps! :)
Answer:
B. 
Step-by-step explanation:
Well slope-intercept form is
.
Let's start with the slope.
In this case, finding the slope is easy.
It should have a negative slope.
So we can cross out answer choices A. and C.
Also, we can cross out D. because it just makes no sense, -10/3, if you start from the y-intercept and go down 10 and across 3, yeah that's
not the slope.
So we can cross out D.
The only answer choice left is B.
We can tell the y-intercept is 1/2 because like come on so B is the correct answer.
B. 
Hey there! :D
Think of it this way. The question is saying that the text messages are all equally the same value, or expense. If you were to divide 16 by $3.20, you would find that each text was the same amount to send. That the input (the number of text messages) is directly related in the same pattern to the output (the cost of the text messages).
A. What is the constant of proportionality in this proportional relationship?
A constant of proportionality is what makes x directly relate in proportion to y. We are trying to find the variable that makes y= (?)x
16y= 3.20x
Divide both sides by 16.
y=0.20x or y=0.2x
The constant is the value that goes with the variable. .20 is the constant. '
B. Write an equation to represent this proportional relationship. Make sure to define the variables you use.
We already know that 0.20 is the constant number. In other words, every text message cost $.20.
Text messages= T cost= C
C= T(0.20)
For every text message (T), it is multiplied by 0.20, to make the accurate cost (C).
I hope this helps!

11/2 is greater than 4/8
11/2=5.5
4/8=1/2=0.5
The radius of the circle is 3.12 inch.
<h3>What is isosceles triangle?</h3>
A triangle having two sides of equal length. Additionally equal are the angles that face the equal sides. Triangle of isosceles. Having two identical sides and angles.
Calculation for the radius of the circle;
Consider the isosceles triangle ABC inscribed in a a circle (attached figure)
Sides AB = AC = 5 inches.
Side BC = 6 inches.
Join OB, OC and OA.
Draw perpendicular on BC from AD which passes from the centre O.
OD bisects BC at point D.
So, BD = DC = 3 inches.
In the right angled triangle ABC
AB² = AD² + BD²
5² = AD² + 3²
AD² = 16
AD = 4 inches.
Let the radius of the circle be r.
Then, OB = OC = OA = r
OD = AD - AO
OD = 4 - r
In the right angled triangle OBD;
OB² = OD² + BD²
r² = (4-r)² + 3³
On solving,
r = 25/8 = 3.12
Therefore, the radius of the circle comes out to be 3.12 inches.
