the vertex for f(x)=-7(x+8)^2+ 3 is the minimum for that function ture or false
Answers
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
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
Answers
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.

Divide 3/5 by 1/2 as a reduced fraction.
Answers
Answer:
You can't divide two fractions together, so you multiply the second fraction by taking its reciprocal.
[tex]\frac{3}{5} * \frac{2}{1} \\\\= \frac{6}{5}[/tex]
If we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].
Given that,
The fraction is [tex]\frac{3}{5}[/tex].And, the other fraction is [tex]\frac{1}{2}[/tex].Now it should be divided to come as a reduced fraction.So, the decreased fraction should be
[tex]= \frac{3}{5} \times \frac{2}{1} \\\\= \frac{6}{5}[/tex]
Therefore we can conclude that if we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].

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'?
Answers
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)find the value of x in the figure below

Answers
Answer:
answer for y=2/3x+2: y=2/3x+2
answer for -2x+3y=6: x=3/2y-3
pls give brainliest
Answer:
There are infinitely many solutions.
Step-by-step explanation:
There are infinitely many solutions because if you solve the equations, you will find that both of the equations are actually the same, so there is infinitely many solutions.
Showing that both equations are equal: y=2/3x+2 -2x+3y=6
y=2/3x+2 Multiply by 3 on both sides
3y=2x+6 Rearrange (-2x on both sides)
3y-2x=6 More rearrangement
-2x+3y=6 Now, if you look back at the second equation, you will see that they are both the same.
