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 equation represents a line which is parallel to the line 5x-4y=-12?
Answers
Answer:
Attached image
1. 5x-4y=12 (move the x)
2. -4y=12-5x (it’s negative 5 because you do the opposite of positive 5)
3. -4y=12-5x (divide the number in front of y from both sides)
4. Slope should be (5/4) and b should be 3
5. Equation should be y=(5/4)x+3
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.

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.

Answers

The slope is 3/4 and the y-intercept is -5.

Your equation is already in slope-intercept form, so all you have to do is look at it. Slope-intercept form looks like y = mx + b, where m is the slope and b is the y-intercept. Hope that helps!
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.

Answer:
The answer is the first option x(x-4)(x-1)/2(x+4).
Step-by-step explanation:
because when you simplify after multiplying the denominator is 2x+8 when you simplify that its 2(x+4) and for the numerator after multiplying you get x^3−5x^2+4x when you simply that you get x(x-4)(x-1). Answer would be x(x-4)(x-1)/2(x+4).
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.

= 4m² - 1.5m + 2 + 9m - 2m³ + 2m
= 4m² + (-1.5m + 9m + 2m) + 2 + 2m³
= 4m² + 9.5m + 2 + 2m³
= 2m³ + 4m² + 9.5m + 2
2. (-3y + 2y² - 6) + (3y + 4y² + x)

Answers
Answer:
length = 20 breadth = 10
Step-by-step explanation:
divide 900 by 15
= 60
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

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.
