Dont bother answering if you won't show how you got it
Answers
The solution to the system of equations is (-1.189, 3.587) and (1.189, 3.587)
How to solve the system of equations?The system of equations is given as
y=e^x+e^-x
y=5-x^2
See attachment for the graph of both equations
From the attached graph, the curve intersect at
(-1.189, 3.587) and (1.189, 3.587)
Hence, the solution to the system of equations is (-1.189, 3.587) and (1.189, 3.587)

Answer:
5 5/6 hours
Step-by-step explanation:
We can add the times, but it is more convenient to use multiplication.

A whale can stay underwater 7 times as long as x minutes more than a platypus can. Write an equation that states the relationship of the minutes these two mammals can stay underwater
Answers
Answer:
Step-by-step explanation:
Using the information provided we can create the following two equations each of which calculates the total number of minutes that the whale (w) or the platypus (p) can stay underwater. In order to solve each, you would need the value of at least 1 of the mammals.
w = 7 * (p+x)
p = (w / 7) - x
The w in these equations represents the number of minutes the whale can stay underwater while the p represents the number of minutes that the platypus can stay underwater.

The area of the rectangle is 35/9 square inches.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To find the area of a rectangle,
We multiply the length by the width.
Length = 2 1/3 = 7/3 inches
Width = 1 2/3 = 5/3 inches
Area = Length x Width
Area = (7/3) x (5/3)
Area = 35/9 square inches

I need only help on 11-14 please someone help me

Linear function definition: a function that will create a straight line when graphed.
11 is not a linear function (not a straight line), but 12 is.
For the tables, you can either plot out the graph or just look at the number patterns. A linear function's numbers will always increase/decrease accordingly at a constant rate. For example, in 14, you notice that as x increases by 1, y decreases by 2. This means it is a linear graph.
In 13, as x increases by 1, the output y increases but at a different rate each time. It increased by 3 at first, then 5, then 7. Hence, it is not a linear function. What is it then? It is an exponential function.

a
y = x + 34
b
y = 4x + 30
c
y = 4x + 42
d
y = x + 42
Answers
Answer: B
If you look at the table, you notice that he earns 30 without selling ice cream bars. This is his fixed salary.
When he sells one ice cream bar, he earns 34, which means he gets 4 dollars for each bar he sells.
The equation that best represents the relationship between x and y is b) y = 4x + 30, because 4 dollars × number of ice cream bars + fixed salary equals his total earnings.
Given the sequence {2,-1,-4,-7} find a25
Answers
Answer:
-70
Step-by-step explanation:
This is an arithmetic progression with a difference of -3
Formula for AP is
Sn = a + (n - 1) d
Where
a is the first term, 2
n is the term we're looking for, 25
d is the arithmetic difference, -3
a25 = 2 + (25 - 1) -3
a25 = 2 + (24) -3
a25 = 2 - 72

Alex is y years old. Bella is 4 years older than him .Carla is double Alex's age. The sum total of their age is 32
Form and solve an equation to work out the ages of the three children
Answers
Answer:
Alex is 7, Bella is 11, and Carla is 14
Step-by-step explanation:
Equation is 32=y+2y+(y+4)
To solve:
First combine like terms (the y's)
32=4y+4
Subtract 4 from both sides
28=4y
Divide both sides by 4 to get y alone
7 =y (Alex's age)
Bella is 4 years older than Alex so 7+4 = 11
Carla is 2 times older than Alex so 2 • 7 = 14
Their ages are supposed to add up to 32.
7+11+14
18+14

What is the equation of the line that passes through (-3, -1) and has a slope of 3/5 ? Put your answer in slope-intercept form.
y = 3/5x + 4/5
y = -3/5 x - 4/5
y = 3/5x - 4/5
Answers
I hoped this helped
first plug the slope and the given point into point-slope from: (y-y1) = m (x-x1)
m=slope= 3/5
point=(x1,y1) = (-3,-1)
(y+1) = 3/5 (x+3)
solve for y to get slope-intercept form
y+1 = 3/5x + 9/5
y = 3/5x + 4/5
