Can I have Brainliest please?
Answer:
[tex]\frac{-1}{8}[/tex]
Step-by-step explanation:
So first find the greatest common factor of the denominators
GCF of 2 , 4 and 8 is 8
Then :
[tex]\frac{-4 + 6 - 3}{8}[/tex]
So you do this to get the above answer:
8 divided by the denominator times the numerator.
You still need to work it out
-4 + 6 = 2
[tex]\frac{2- 3}{8}[/tex]
2 - 3 is -1
Thus the answer is [tex]\frac{-1}{8}[/tex]

Find the minimum or maximum value of the function y=9x2+7. Describe the domain and range of the function, and where the function is increasing and decreasing. The minimum value is Response area. The domain is Response area and the range is Response area. The function is decreasing to the Response area of x= Response area and increasing to the Response area of x= Response area.
The given function is [tex]y=x^2+7[/tex].
Minimum or maximum value:
At the extremum (maximum or minimum) value, the function will have zero slope. So, differentiate the given function once and equate it to zero to get the extremum point.
dy/dx=0
[tex]\Rightarrow 18x=0\cdots(i)[/tex]
[tex]\Rightarrow x=0[/tex]
Now, check whether the point x=0 is corresponding to the maximum value or minimum value by differentiating the function twice,
[tex]\frac {d^2y}{dx^2}=18[/tex]
As [tex]\frac {d^2y}{dx^2} >0[/tex] for all value of x, so x=0 is the point corresponding to minima.
Put x=0 in the given function to get the minimum value.
[tex]y_{min}=9(0^2)+7[/tex]
[tex]y_{min}=7[/tex]
Domain and range:
The function defined for all the values of the independent variable, x.
So, the domain is [tex](-\infty, \infty)[/tex].
The range of the function is the possible value of y.
The minimum value, for x=0, is y=7.
The maximum value, as [tex]x\rightarrow \infty \;or\; -\infty, y\rightarrow \infty[/tex].
Hence the range of the function is [tex][7,\infty)[/tex].
The value of x for which the function is increasing and decreasing:
If the slope of the function is negative than the function is decreasing, so
Then, from equation (i), the value of x for which dy/dx<0,
18x<0
[tex]\Rightarrow x<0[/tex]
Hence, the function is decreasing for [tex]x\in {-\infty, 0)[/tex] .
While if the slope of the function is positive than the function is increasing, so
Then, from equation (i), the value of x for which dy/dx<0,
18x>0
[tex]\Rightarrow x>0[/tex]
Hence, the function is increasing for [tex]x\in {0,\infty)[/tex]

hayley jogs 3/4 miles in 1/6 of an hour
maxwell jogs 2/3 miles in 2/15 who is faster and how much faster
Maxwell is faster and faster by 0.5 miles/hour.
Given that, Hayley jogs 3/4 miles in 1/6 of an hour and Maxwell jogs 2/3 miles in 2/15.
We need to find who is faster and how much faster.
What is an average speed?An average speed is the total distance travelled divided by the total time travelled. The formula to find the average speed is Average speed = Total distance / Total time.
Now speed of Hayley= 3/4 ÷ 1/6
=3/4 × 6=9/2
=4.5 miles/hour
Speed of Maxwell= 2/3 ÷ 2/15
= 2/3 × 15/2 = 5 miles/hour
The difference in the speed =5-4.5=0.5 miles/hour
Therefore, Maxwell is faster and faster by 0.5 miles/hour.

2. Tyler is solving this system of equations:
4p + 2g = 62
8p - q = 59
He can think of two ways to eliminate a variable and solve the system:
o Multiply 4p + 2g = 62 by 2, then subtract 8p - q= 59 from the result.
• Multiply 8p-q=59 by 2, then add the result to 4p + 2q = 62.
Do both strategies work for solving the system? Explain or show your reasoning.
please help out ://
Answer:
Both of them work
Step-by-step explanation:
by multiplying the first equation by 2 it creates the same coefficient in front of "p" for both equations. same for the second equation and "q".
Both strategies works since we can easily eliminate a variable from both equations.
Given the simultaneous equation solved by Tyler
4p + 2q = 62
8p - q = 59
In order for him to eliminate a variable to solve the system of equations, he must ensure that the coeffiecient of the variable to be eliminated are equations in both expressions. To do that;
Multiply 4p + 2g = 62 by 2, then subtract 8p - q= 59 from the result. This will give;8p + 4g = 124
8p - q = 59
Subtract
4q + q = 124 + 59
5q = 183
The second required strategy is to Multiply 8p-q=59 by 2, then add the result to 4p + 2q = 62, to have:
16p-2q=118
4p + 2q = 62
Adding up
16p + 4p = 118 + 62
20p = 180
p = 9
We can see that both strategies works since we can easily eliminate a variable from both equations.

Penelope has a birdhouse that is 4 and 9/10 feet
above the roof of her garage. She has a second
birdhouse that is 5.36 feet below the roof of
her garage. What is the distance between the
birdhouses?
Answer:
The distance between the bird houses are 10.26 feet
Step-by-step explanation:
The distance between the birdhouses is 10.26 feet.
What is simplification?A mathematical expression gets simpler when it is transformed into an equivalent, frequently shorter statement. One strategy for promoting uniformity in job effort, cost, and time is procedure simplification. It lessens diversity and variation that is harmful, unwanted, or unneeded.
Given, Penelope has a birdhouse that is 4 and 9/10 feet above the roof of her garage. She has a second birdhouse that is 5.36 feet below the roof of her garage. thus,
Distance between garage roof and birdhouse = 4.9 feet
Distance between garage roof and second birdhouse = 5.36 feet
Since these birdhouses are in the opposite directions of the garage roof
Hence the total distance between them = 4.9 + 5.36
the total distance between birdhouses is 10.26 feet
Therefore, the Two birdhouses are 10.26 feet apart from each other.

= -9 2/3 - 8 2/9
= -17 8/9
-12.48 - (-2.99) - 5.62= -12.48 + 2.99 + 5.62
= -15.11
-19 2/9 - 4 1/9 - ( -3 4/9)= -173/9 - 37/9 + 31/9
= -179/9
= -19 8/9

If a point O(x, y) divides line segment XY in the ratio of n:m and the endpoints of the segment are [tex]X(x_1,y_1)\ and\ Y(x_2,y_2)[/tex], the coordinates of O is:

Given that A(6, -6) and C(-6, 2). Pont B is on AC such that:
AB = (3/4)AC
AB/AC = 3/4
Therefore point B divides the line AC in the ratio of 3:1. Let point B be at (x, y), therefore:
[tex]x=\frac{3}{3+1}(-6-6)+6=\frac{3}{4}(-12)+6=-9+6=-3\\ \\y=x=\frac{3}{3+1}(-2-(-6))-6=\frac{3}{4}(4)-6=3-6=-3[/tex]
Therefore the location of B is at (-3, -3)

A secretary earns $12 an hour and worked a total of 47 hours last week she earns time and a half for work beyond 40hours calculate her pay
Answer:
$606
Step-by-step explanation:
For the first 40 hours, she was making $12. With this, we can do 12x40, which is 480$. We can store that in a safe space for later access. Afterwards, since the problem says that "after 40 hours she earns time and a half for her work" we can assume she gets 1.5x her pay after 40 hours, which is $18 (We can get this by 12 / 2 = 6. Then do 12 + 6 = 18). Then we can do 18x7 because she worked 7 hours over 40. With that, we get 126$. Now we can do 480$ + 126$ = 606$. So, she earned 606$.
if pqr=tsr what are the congruent corresponding parts
Answer: The congruent corresponding parts:
∠P≅∠T (first letter) , ∠Q≅∠S (second letter), ∠R≅∠R (third letter)
segment PQ ≅ segment TS , segment QR≅ segment SR , segment PR ≅ segment TR.
Step-by-step explanation:
We know that if two triangles area congruent then the corresponding parts area congruent.
Given: ΔPQR ≅ ΔTSR
Then, ∠P≅∠T (first letter) , ∠Q≅∠S (second letter), ∠R≅∠R (third letter)
segment PQ ≅ segment TS , segment QR≅ segment SR , segment PR ≅ segment TR.
Hence, the congruent corresponding parts:
∠P≅∠T (first letter) , ∠Q≅∠S (second letter), ∠R≅∠R (third letter)
segment PQ ≅ segment TS , segment QR≅ segment SR , segment PR ≅ segment TR.
The corresponding parts of a triangle are parts that have the same measurement.
The corresponding parts are: P & T, Q & S and R & R
The given parameter is:
[tex]\mathbf{\triangle pqr \cong \triangle tsr}[/tex]
The above congruence equation means that:
[tex]\mathbf{\angle p \cong \angle t}[/tex]
[tex]\mathbf{\angle q \cong \angle s}[/tex]
[tex]\mathbf{\angle r \cong \angle r}[/tex]
Hence, the corresponding parts are:
