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

Does the system have a no solution or infinitely many solutions
Y=2/3x+2-2x+3y=6
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.
please answer ASAP! solve the equation

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
Lucia needs to buy a ladder to reach her roof. The edge of the roof is 21.125 feet high. To use a ladder safely, the base of a ladder should be 1 foot away from a building for every 3.25 feet of building height. The ladder should extend 3 feet longer than the edge of the roof. How long does the ladder need to be? Round your answer to the nearest tent
Answers
Answer:
The length of the ladder is 25.1ft
Step-by-step explanation:
We are given
Height of the building = 21.125ft = a (let)
On forming a triangle we have the height of the building as 'a'
It says that the base of a ladder should be 1 foot away from a building for every 3.25 feet of building height.
so for 21.125ft of height of building = 21.125/3.5 = 6.5ft
we need the base of the ladder to be at 6.5ft away from the building on the ground.
Let 6.5ft = b
Now we have the height of the building 'a' and the base distance of the ladder from the building 'b'
Applying Pythagoreans theorem
[tex]\sqrt{a^2 + b^2} =c^2[/tex] where c represents the ladder length
on substituting the values of a and b
we get c= 22.1ft
but the ladder is 3ft longer than the edge of the roof
so final length of the ladder = 22.1 +3 = 25.1ft
if 196 soldiers are arranged in a square field how many soldiers are there in the first row?
Answers
Answer:
49
Step-by-step explanation:
We will need the Perimeter formula to find this out. The perimeter of the square in this problem is 196 for the soldiers. P=4a, 196=4a. Divide both sides by 4. 49 = a, so 1 side is 49.

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.
Answers
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.

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].
