Which equation represents a proportional relationship where the constant of proportionality is 2? * y=2+k k=2y y=2+x y=2x
Answer:
y = 2x
Step-by-step explanation:
here in this case, x = independent variable whereas y is the dependent variable.
Now, Equation that represents a proportional relationship with a constant or proportionality of 2 is y =2x.
as y= 2x
⇒ y/x = 2

Priya is simplifying the expression $$ Her work is shown to the left. Priya's work is incorrect. Explain the error she made
Step-by-step explanation:
P.S - The exact question is -
Given - Priya is simplifying the expression -2(4 - 2x) - 3 - 2x Her work is shown to the left.
To find - Priya's work is incorrect. Explain the error she made.
Proof -
Priya simplified the problem as follows :
-2( 4 - 2x ) - 3 - 2x
-8 - 2x - 3 - 2x
-11 - 4x
But the simplification has to be like
-2( 4 - 2x ) - 3 - 2x
⇒-2(4) - 2(-2x) - 3 - 2x
⇒-8 + 4x - 3 - 2x
⇒-8 - 3 + 4x - 2x
⇒-11 + 2x
So, Priya made an error in the second line.
In the second line it has to be -8 + 4x - 3 - 2x but Priya has written -8 - 2x - 3 - 2x.

If Circle A has a radius that is five more than twice as long as the radius of circle B and the sum of the diameters of the circle is 88 inches, find the area and circumference of circle A
Answer:
Circumference of a circle A = [tex]389.7 \,\,inches[/tex]
Area of a circle A = 12081.1 square inches
Step-by-step explanation:
Let [tex]r[/tex] denotes radius of circle B.
Circle A has a radius that is five more than twice as long as the radius of circle B.
So,
Radius of circle A = [tex]5+2r[/tex]
Diameter of circle = 2 (radius of circle)
So,
Diameter of circle B = 2r
Diameter of circle A = [tex]2(5+2r)[/tex]
Sum of the diameters of the circles A and B = [tex]2r+2(5+2r)[/tex]
[tex]=2r+10+4r[/tex]
[tex]=6r+10[/tex]
As sum of the diameters of the circles is 88 inches,
[tex]6r+10=88\\6r=78[/tex]
[tex]r=13[/tex] inches
Radius of a circle A = [tex]2(5+2r)[/tex]
[tex]=2[5+2(13)][/tex]
[tex]=2(5+26)[/tex]
[tex]=2(31)[/tex]
[tex]=62[/tex] inches
Let R denotes radius of a circle A.
R = 62 inches
Circumference of a circle [tex]=2\pi R=2\pi (62)=124\pi =124(\frac{22}{7})=389.7 \,\,inches[/tex]
Area of a circle [tex]=\pi r^2=\pi (62)^2=3844\pi=3844(\frac{22}{7})=12081.1[/tex] square inches

and 76/100=76%
Please I really need someone to help
Answer:
Step-by-step explanation:
so a rhombus is two triangles put together, the area of a triangle is 1/2 b*h and since we've got two it's 2 ( 1/2 b * h ) so then it' just b * h
will be the area of the rhombus.
the base is WY = 24 the height is 1/2 XZ = 30 so 15
24*15 = 360
pls help I can't get it
Answer:
30
Step-by-step explanation:
Solve for the hypotenuse for the bottom triangle (a^2+ b^2=c^2). You should get 40. After solving that you should be able to solve for c in the top triangle which should get you 30.
Find the slope of the line. 10 point if you solve.

Step-by-step explanation:
mode is the value that appears most often in a set of data.
been stuck on this question. plz help me i will give u brainliest!
Answer:
the sum of A, B, C and E = 23Explanation:
single cone = $3
double cone = $5
total single = A = 3s
total double = B = 5d
As + Bd = 57
Cs + Ed = 15
A = 3 , B = 5
3s + 5d = 57
s + d = 15 (we don't know C and E yet)
multiply the second equation by 3 and substract it from the first equation
3s + 5d - 3s - 3d = 57 - 45
2d = 12
d = 6
Ed = 6
Cs = 15 - 6 = 9
A = 3 ($3)
B = 5 ($5)
C = 9 (single cones)
E = 6 (double cones)
Check:
(9 single cones × $3) + (6 double cones × $5) = 27 + 30 = 57
9 single cones + 6 double cones = 15
the sum of A, B, C and E:
A+B+C+E = 3+5+9+6 = 23
Please answer with explanation
Answer:
1. if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = 6/2= 3. Thus, the equation describing this direct variation is y = 3x.
2. Partial Variation, where two variables are related by a formula, such as the formula for a straight line (with a non-zero y-intercept)
example :
in the milk factory Carol makes $10 per hour but gets an extra $20 from another job. since Carol gets a $20 allowance regardless of how much she works, if we want to represent Carol's situation in the form of an equation, it would be
Y=10x + 20
therefore if she worked zero hours
(Y=10(0) + 20),
she would still make $20 unconditionally and for every hour she works, she gets $10 more including the initial $20.
thus Carol's equation would be a partial variation, since her income doesn't entirely depend on how much she works.
3. a relation is non linear because it is has a direct relationship between an independent variable and a dependent variable.
In a relation, changes in the output do not change in direct proportion to changes in any of the inputs.
relations does not create a straight line but instead creates a curve.

Triangle Ratios (Sides)
Find the value of c. Round to the nearest tenth!
Answer:
x =30.7
Step-by-step explanation:
Here, we want to find the value of x
To get this, we use the appropriate trigonometric ratio
From what we have, we have the side facing an angle which is the opposite and the side not facing an angle or the right angle; this is the adjacent
The trigonometric identity that links the opposite and the adjacent is called the tan
It is the ratio of the opposite to the adjacent
Thus, we have;
tan 61 = x/17
x = 17 * tan 61
x = 30.7

Tracey built a small boat and recorded the distance it traveled. The table below shows the distance traveled (f) during the first 4 seconds after starting (p).
Elapsed Time
(seconds) Distance Traveled
(feet)
1 4.2
2 8.4
3 12.6
4 16.8
Which of the following equations represents the relationship between the distance traveled and the elapsed time?
p = 4.2f
f = 4.2p
p = 4.2 + f
f = 4.2 + p

Answer:
600,000 km²
Step-by-step explanation:
Using the exponential regression calculator : the regression fit obtained for the data is :
36510 * (1.08^x)
After 40 years ;
x = 40
Hence,
y = 36510 * 1.08^40
y = 36510 * 21.72452
y = 793,162.27 km
Hence, y is closest to 800,000 km

Find the value of x.
Answer:
x = 45
Step-by-step explanation:
All triangles add up to 180°
x + 75 + 60 = 180
x + 135 = 180
x = 180 - 135
x = 45
