Answer:
13
Step-by-step explanation:
The distance between the points is the magnitude of their difference.
|(-2-3i) -(3+9i)| = |-5 -12i| = √(5² +12²) = 13
The distance between the point is 13 units.

4(3+2x) + 2 = 46 , solve for x I need help I'm a bit confused
Answer:
x=4
Step-by-step explanation:
4(3+2x)+2=46
12+8x+2=46
12+8x=44
8x=32
x=4
Answer:
4
Step-by-step explanation:
You need to start with the 2x inside the parenthesis
If you put 4 in place of x you get 8
8+3=11
then because there isnt any sign between 4 and the parenthesis you multiply
4x11=44
then its easy
44+2=46

A baker in 70 minutes iced 40 cupcakes and in 49 minutes he iced 28 cupcakes what is the constant of proportionality? express your awnser in decimal form.
Answer:
1 cupcake is made in 1.75 minutes.
1.75 minutes
Step-by-step explanation:
Divide 70 by 40 = 1.75.
49/28=1.75
The constant of proportionality of the given data is 0.57.
What is constant of proportionality?The constant of proportionality is the ratio of two proportional values at a constant value.
Now it is given that,
Time taken for icing 40 cupcakes = 70 minutes
∴ Icing of cupcakes in 1 minute = 40/70
= 0.57
Time taken for icing 28 cupcakes = 49 minutes
∴ Icing of cupcakes in 1 minute = 28/49
= 0.57
⇒ constant of proportionality = 0.57
Thus, the constant of proportionality of the given data is 0.57.

the vertex for f(x)=-7(x+8)^2+ 3 is the minimum for that function ture or false
Answer:Do you what it in vertex because if you do the answer is (-8,3)
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = - 7(x + 8)² + 3 ← is in vertex form
with (h, k) = (- 8, 3 )
• If a > 0 then vertex is a minimum
• If a < 0 then vertex is a maximum
Here a = - 7 < 0 , thus
(- 8, 3 ) is a maximum

Triangle PQR with coordinates P(3,-4), (6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically. What will
be the coordinates of P'Q'R'?
Answer:
(0, 2), (3, 5) and (3, 0)
Step-by-step explanation:
Since, Points P(3,-4), Q(6, -1), and R(6, -6) is translated -3 units horizontally and 6 units vertically.
Therefore,
P' (3 - 3, - 4 +6) = P' (0, 2)
Q'(6 - 3, - 1 + 6) = Q'(3, 5)
R'(6 - 3, -6 + 6) = R'(3, 0)
Thus, the coordinates of P'Q'R are (0, 2), (3, 5) and (3, 0).
Answer:
P'(0, 2), Q'(3, 5), R'(3, 0)Step-by-step explanation:
Given
Points P(3,-4), Q(6, -1), R(6, -6) Translation: x -3, y + 6New points:
P'(3 - 3, -4 + 6) = P'(0, 2)Q'(6 - 3, -1 + 6) = Q'(3, 5)R'(6 - 3, -6 + 6) = R'(3, 0)hurryyy!! Otero translated the phrase "three less than a number" into the expression 3 - X. Which best describes the accuracy of
Otero's expression?
It is accurate. The phrase can be translated as "three" = 3, "less than" = subtraction, and "a number" = X, SO 3- X is
the correct expression.
It is inaccurate. Three is being subtracted from a number, so X-3 is what he should have written.
It is inaccurate. Three is being compared to a number, so 3
It is inaccurate. Three is being added to a number, so 3+ x is what he should have written.
Answer:
A. It is accurate. The phrase can be translated as “three” = 3, “less than” = subtraction, and “a number” = x, so 3-x is the correct expression.

Jeffrey and Frank walk at different speeds.Frank’s walking speed can be represented by the equation y=85x, where is the time in minutes and y is the distance in meters. The distance Jeffrey walked over the time is shown on the graph below
Answer:
Option (C)
Option (C)
Option (A)
Step-by-step explanation:
Part A.
Frank's walking speed can be represented by the equation.
Equation representing the speed is,
y = 85x
[tex]\frac{y}{x}=85[/tex]
Therefore, walking speed of Frank = 85 meters per minute.
Option (C) will be the answer.
Part B.
Distance walked over the time by Jeffrey is given by the graph attached.
Equation for the speed will be,
y = [tex](\frac{400}{5})x[/tex]
y = 80x
Therefore, walking speed of Jeffrey = 80 meters per minute
Difference in the speed of Frank and Jeffrey = 85 - 80 = 5 meters per minute.
Jeffery walks 5 meters per minute slower than Frank.
Option (C) will be the answer.
Part (C)
Distance traveled by Frank in 16 minutes,
y = 85(16) = 1360 meters
Time taken to travel the same distance by Jeffrey will be,
1360 = 80x
x = [tex]\frac{1360}{80}=17[/tex] meters per minute
Option (A) will be the answer.
