Okay so, to solve these problems what you're gonna want to do is substitute the given x and y values into the equation.
For example, number 7.
11(d-c) + 3(c+d), when c=6, d=9
if d=9, you will substitute the d in the problem to 9.
11(9-c) + 3(c+9)
if c=6 you will substitute c for 6.
11(9-6) + 3(6+9)
You can solve now that you have a simpler problem to work with.
11(9-6) + 3(6+9) first...
11(9-6) 11*9=99 11*-6=-66, so, 11(9-6)= 99-66= 33.
3(6+9) 3*6=18 3*9=27 18+27=45
33+45=78
Your answer for number 7 is 78.
Hope this helps, just do the same for the other problems like this one.

What is the distance between the points (-2.5,6.5) and (2.5,6.5)
Answer:
5 units
Step-by-step explanation:
The two points have the same y-coordinate so are on a horizontal line. The distance between them is the difference of their x-coordinates:
2.5 -(-2.5) = 2.5 +2.5 = 5.0
The distance between the points is 5 units.

Answer:
x = [tex]\frac{1-by}{y-a}[/tex]
Step-by-step explanation:
y = [tex]\frac{ax+1}{x+b}[/tex] ← multiply both sides by (x + b)
y(x + b) = ax + 1 ← distribute parenthesis on left side by y
yx + by = ax + 1 ( subtract ax from both sides )
yx - ax + by = 1 ( subtract by from both sides )
yx - ax = 1 - by ( factor x out of each term on the left side )
x(y - a) = 1 - by ← divide both sides by (y - a)
x = [tex]\frac{1-by}{y-a}[/tex]
Answer:
Step-by-step explanation:
1. Eliminate fractions by multiplying both sides of this equation by x + b:
y(x + b) = ax + 1
2. Perform the indicated multiplication: xy + yb = ax + 1
3. Group together the x-terms xy - ax = 1 - yb, or x(y - a) = 1 - yb
1 - yb
4. Divide both sides by (y - a): x = ----------------
y - a
Describe how to determine f(x) and g(x) when x=5
Answer:
243 and 394
Step-by-step explanation:
f(x) is the exponential as its values increase by 3 every hour, then
when x = 5
f(5 ) = 81 × 3 = 243
---------------------------
g(x) is linear as there is a common difference between consecutive values of + 3 , then
when x = 5
g(x) = 391 + 3 = 394

Pardis recently deposited $5,000 in a savings account that pays a return of 2 percent per year. Explain why her investment will grow over the years. What opposing force will impact the value of her investment?
Answer:
Her investment will grow over the years due to the 2 percent interest. Inflation will impact the value of her investment
For the given data. the simple interest will be $100.His investment will grow over the years. Because of the simple interest.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
It is given that, Pardis recently deposited $5,000 in a savings account that pays a return of 2 percent per year.
Principal = $5,000
Rate= 2%
Time= 1 year
SI = (P×R×T)/100
SI = (5000×2×1)/100
SI=100
Thus, for the given data. the simple interest will be $100.His investment will grow over the years. Because of the simple interest.

The Amount of sales tax on a new car varies directly to the purchase price of the car. On a 25,000 car, sales tax is 1,750. What's the purchase price of a new car with 3,500 in sales tax?
Please show your work because I still don't understand it and don't know how to do it.
Answer:
50,000
Step-by-step explanation:
1st car had $1,750 tax
2nd car has $3,500 tax
1750(2) = 3500
so your tax doubled so the price must be doubled.
The car is $50,000
Algebraically using direct variation:
t = kp where t=tax, p = purchase price,
and k is constant of variation
1750 = 25000k
k = 1750/25000
k = 0.07
Your equation is: t = 0.07p
3500 = 0.07p
p = 3500/0.07
p = $50,000

Answer:
x=180-95-57 (sum of triangle)
or,x=28
Step-by-step explanation:
Answer:
x = 27
Step-by-step explanation:
solving similarities using equations:
→[tex]\frac{CD}{QD} = \frac{RD}{BD}[/tex]
→ [tex]\frac{x}{39} = \frac{18+x}{26+39}[/tex]
→ [tex]\frac{x}{39} = \frac{18+x}{65}[/tex]
→ 65(x) = 39(18+x)
→ 65x = 702 + 39x
→ 65x - 39x = 702
→ 26x = 702
→ x = 27

Ana wished to compute for the average speed of a moving bus on a straight line highway, She noted the distance covered. What other quantity should she record?
A. Acceleration
B. Direction
C. Time
D. Velocity
The other quantity needed to calculate the average speed is time.
What is average speed?
Average speed is the total distance travelled per time. It is how fast an object moves with respect to time.
Average speed = total distance / total time
For example, if the distance travelled is 100km and the total time is 10 hours, average speed is 10 km/hr (100 / 10).
