What is the domain of the function?
X+6
f(x)=(x-7)(x+5)
A all real numbers except 7
Ball real numbers except 5 and -7
Call real numbers except -5 and 7
D all real numbers
The required domain of the function is all real numbers except -5 and 7. Option C is correct.
Given that,
f(x) = (x + 6) /[(x-7)(x+5)]
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
Given function,
f(x) = (x + 6) /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.
Thus, the required domain of the function is all real numbers except -5 and 7. Option C is correct.

Joe bought g gallons of gasoline for $2.65 per gallon and c cans of oil for $3.45 per can. a. What expression can be used to determine the total amount Joe spent on gasoline and oil? b. If he bought 8.4 gallons of gasoline and 9 cans of oil, how much did he spend in all?
Step-by-step explanation:
PART A
a=total amount
c=cans of oil
g=gasoline
a=2.65g+3.45c
PART B
a=2.85(8.4)+3.15(6)
a=23.94+18.90
a=42.84

I need help with geometry
Answer:
Rhombus and angle 1 = 35
Step-by-step explanation:
The parallelogram has the same marking on each of its sides, indicating that all the sides are equal in length. It is, therefore, a rhombus.
It is given that one of the angles measures 110 degrees. The other angle is 70 degrees (because 180 - 110 = 70). Since it is bisected by a line, divide the angle by 2 (70/2). You get 35 degrees. Therefore, the measure of angle 1 is 35 degrees.
I hope this helps! :)
Two trains leave stations 520 miles apart at the same time and travel toward each other. One train travels at 110 miles
per hour while the other travels at 90 miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.
Answer:
They wont meet
Step-by-step explanation:
The one going 110 will pass before the other one can reach it.
Please mark me the brainliest, 5 stars, and a thanks! Have a great day!
It will take 2.6 hours (or 2 hours and 36 minutes) long for the two trains to meet when Two trains leave stations 520 miles apart at the same time and travel toward each other.
To find the time it will take for the two trains to meet, we can use the concept of relative speed.
The two trains are traveling towards each other, so their speeds add up. The combined speed of the two trains is:
110 mph + 90 mph = 200 mph
To determine the time it will take for the trains to meet, we can divide the total distance they need to cover (520 miles) by their combined speed (200 mph):
Time = Distance / Speed
Time = 520 miles / 200 mph
Time = 2.6 hours
Therefore, it will take 2.6 hours (or 2 hours and 36 minutes) for the two trains to meet.

What is 4/9 x 5/7 x 1/2
Answer:
0.16
Step-by-step explanation:
4*5*1=20
9*7*2=126
20/126=10/63
Answer:
10/63
Step-by-step explanation:
First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.

The balance after 10 years is $
Step-by-step explanation:
step 1. let's call the balance A, the initial amount P, the yearly rate r, the number of compounds yearly n, and the time t.
step 2. A = P(1 + r/n)^(nt) (compounding equation)
step 3. A = 8500(1 + .0178/12)^((12)(10))

Slope intercept
Answer:
the slope is 2/7 and the intercept is 4
Step-by-step explanation:
In order to find slope, you use the equation delta y over delta x which is the equation, y2-y1/x2-x1.
In this case you plug in each point and get the equation, 2-4/-7-0 or 4-2/0+7.
Simplify to get 2/7.
To find the intercept, you must see what's the y value when x is 0. In this case it's already given to you, so y intercept is 4.

Autumn invested $69,000 in an account paying an interest rate of 6 3/8% compounded continuously. Jayden invested $69,000 in an account paying an interest rate of 6 1/4% compounded quarterly. After 14 years, how much more money would Autumn have in her account than Jayden, to the nearest dollar?
Answer:
4,038.21
Step-by-step explanation:
I'm going to assume that when you write 6 3/8% that equals 51/8%=6.375%
To find the value in the first equation we have
69000*e^(.06375*14)=168,444.5313
The second equation is as follows
69000(1+(.0625/4))^(14*4)=164,406.3243
Subtract the two and get 4,038.2071

The basking shark can grow to a length of 30 feet. This is 176.47% of the maximum length of the beluga whale. Find the maximum length of the beluga whale. If necessary, round your answer to the nearest tenth.
a) 52.9ft
b) 17ft
c) 5.9ft
d)1.7ft
Answer:
b
Step-by-step explanation:
The maximum length of the beluga whale is 17 feet.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The basking shark can grow to a length of 30 feet.
This is 176.47% of the maximum length of the beluga whale.
Assuming the maximum length of a beluga whale is x feet.
So, 176.47% of x is 30 feet.
∴ (176.47/100)×x = 30.
1.7647x = 30.
x = (30/1.7647).
x = 17 feet.
