Answer:
The answer is 46.
Step-by-step explanation:
First, you will have to add up both functions in order to find the new expression for (g + f)(a) :
g(a) + f(a) = (g + f)(a)
(g + f)(a) = 3a + 3 + 2a - 2
(g + f)(a) = 5a + 1
Next, you have to substitute a = 9 into the function :
(g + f)(9) = 5(9) + 1
(g + f)(9) = 46

Which table contains only values that satisfy the equation
y = 0.25x + 8?
Answers
Answer:
Step-by-step explanation:
y = 0.25x + 8
(0, 8) are coordinates of y=intercept
y = 0.25 × 2 + 8 = 8.50
(2, 8.50)
The last table represnts the given equation.
The fourth table among all the options contains values that satisfy the equation y = 0.25x + 8.
An equation is a combination of two or more expressions, all equal to each other.
Let's check every table if every point in them satisfies the equation y = 0.25x + 8,
Table 1:
To check if (0, 8) satisfies the given equation,
RHS: 0.25 × 0 + 8 = 0 + 8 = 8
LHS: 8 = RHS
This point satisfies the equation.
To check if (2, 8.25) satisfies the given equation,
RHS: 0.25 × 2 + 8 = 0.50 + 8 = 8.50
LHS: 8.25 ≠ RHS
This point does not satisfy the equation.
Table 2:
To check if (0, 0) satisfies the given equation,
RHS: 0.25 × 0 + 8 = 0 + 8 = 8
LHS: 0 ≠ RHS
This point does not satisfy the equation.
Table 3:
To check if (0, 8.25) satisfies the given equation,
RHS: 0.25 × 0 + 8 = 0 + 8 = 8
LHS: 8.25 ≠ RHS
This point does not satisfy the equation.
Table 4:
To check if (0, 8) satisfies the given equation,
RHS: 0.25 × 0 + 8 = 0 + 8 = 8
LHS: 8 = RHS
This point satisfies the equation.
Similarly, all the points can be verified that they satisfy the equation.
Thus, all values in Table 4 satisfy the given equation.

What is (-∞ , -1) ∪ [ 2 , +∞)
Answers
9514 1404 393
Answer:
interval notation for all numbers except those that are at least -1 and less than 2.
Step-by-step explanation:
The ∪ between the two sets of brackets indicates the "union" of two sets. The brackets on the left indicate the interval ...
-∞ < x < -1 . . . . . for a value represented by x
The curved brackets ( ) indicate the end values of the interval are not included, which is why the < symbol is used, and not the ≤ symbol.
The brackets on the right indicate the interval ...
2 ≤ x < +∞ . . . . . for a value represented by x
The square bracket [ ] is used to indicate the end value is included, which is why the ≤ symbol is used in relation to the end-value 2.
By convention, the interval notation lists the left end of the interval first, and always uses curved brackets for infinity.

Albert wants to buy two pomegranates and some peaches • The price of one pomegranate is $1.59. • The price of peaches is $1.19 per pound. Albert wants to no more than $10.00. Which graph represents the number of whole pounds of peaches Albert can buy?
Answers
Answer:
He can buy 5 pounds of peaches.
Step-by-step explanation:
2 pomegranates cost $3.18 so, subtract that from $10.00 and you get $6.82. Multiply the different number of pounds with the cost per pound until you go over $6.82. Then go back a pound and multiply. 5 pounds times $1.19 equals $5.95.

Andre rode his bike at a constant speed. He rode 1 mile in 5 minutes. Which of these equations represents the amount of time t (in minutes) that it takes him to ride a distance of d miles?
t = 5d
t = 1/5d
t = d + 4
t = d - 4
Answers
Answer:
the first one
Step-by-step explanation:
Answer:
A) t=5d
Step-by-step explanation:
Since the problem states "He rode 1 mile in 5 minutes", that means for every mile Andre travels, it will take him 5 minutes for each mile.
Therefore, the equation that best works is t=5d because the coefficient is 5 where it's the slope representing 5 minutes per mile.

= 4m² + (-1.5m + 9m + 2m) + 2 + 2m³

60 divided by 6 because the length is twice the breath
60 / 6 is 10
so ten is the breadth of one side and double that is 20 so the length is 20

At that rate, how many minutes will it
take for the plane's altitude to change
by -5,400 meters?
Please answer I need to finish this now it’s already past due
Answers
Answer:
It would require 12 minutes for the plane's attitude to change by -5,400 meters.
Step-by-step explanation:
As the altitude (or height) of a plane landing at an airport-changes at a rate of -450 meters per minute.
∴ unit rate = -450 meters/per minute
We have to determine how many will it take for the plane's altitude to change by -5,400 meters.
Altitude change per minute = -450 metersi.e.
-450 × 1 = -450 meters (altitude change in 1 minute)
so
-450 × 12 = - 5400 meters (∴ unit rate = -450 meters/per minute)
At this rate, it would require 12 minutes for the plane's attitude to change by -5,400 meters.
Because -450 × 12 = - 5400 meters
Therefore, it would require 12 minutes for the plane's attitude to change by -5,400 meters.
