Divide (-3x^2 - 9x) ÷ (x + 3)
please explain/show work! <33
Step-by-step explanation:
[tex]( - 3 {x}^{2} - 9x) \div (x + 3) [/tex]
This is the original equation so you will open the brackets.
[tex] - 3 {x}^{2} - 9x \div x + 3[/tex]
The x will cross the division sign making it times x.
[tex]3 {x}^{2} - 9x \times x = 3[/tex]
So you will proceed to multiply the 9x by x making it;
[tex]3 {x}^{2} - 9 {x}^{2} = 3 [/tex]
So you will subtract 9x² from 3x² which won't be possible so it will be negative.
[tex] - 6 {x}^{2} = 3 [/tex]
Then you will square root both sides making it;
[tex] - \sqrt{6 {x}^{2} } = \sqrt{3} [/tex]
So the ² will cancel the √ leaving
-6x=√3
-6x=1.73(Divide both sides by -6)
x=0.288

A store sells ice cream with assorted toppings. They charge $3.00 for an ice cream, plus 50 cents per ounce of toppings. If Elena’s ice cream cost $1.50 more than Jada’s ice cream, how much more did Elena’s toppings weigh?
Answer:
3 ounces more
Step-by-step explanation:
50*3 =1.50
3.00+1.50= 4.50
y=100-(1.25)
is it exponential growth or decay ?
what’s the initial value ?
what is the rate of growth or rate of decay ?
Answer:
You should probably double check the problem. The equation you have is just 100-1.25

A cake is removed from an oven. The temperature, in degrees Fahrenheit, of the cake after t minutes can be modeled by the equation, f(x)=70+140e^-0.024t.
What is the temperature of the cake at the moment it is removed from the oven and about how long will it take for the cake to reach a temperature of 80oF ? Round your answer to the nearest whole minute.
Thank you (:
Answer:
210°F
110 minutes
Step-by-step explanation:
Given that :
Temperature of cake t minutes after being removed from oven :
f(x)=70+140e^-0.024t
Temperature T the timee it is removed ;
At this point, the time t = 0
f(t)=70+140e^-0.024t
f(x)=70+140e^-0.024(0)
= 70 + 140(1)
= 210°F
how long will it take for the cake to reach a temperature of 80oF
80 = 70+140e^-0.024t
80 - 70 = 140*e^-0.024t
10/140 = e^-0.024t
0.0714285 = e^-0.024t
In(0.0714285) = - 0.024t
−2.639057 = - 0.024t
t = 2.639057 / 0.024
t = 109.9607
t = 110 minutes

Im so confused pls help
Answer:
2,3
Step-by-step explanation:
Let the first number be x
Hence, its next consecutive integer = x+1
[tex]Reciprocal\ of\ the\ first\ integer\ = \frac{1}{x} \\Reciprocal\ of\ the\ second\ integer\ = \frac{1}{x+1} \\\\As\ we\ are\ given\ that\ their\ sums\ are\ \frac{5}{6} ,\\\frac{1}{x} + \frac{1}{x+1} = \frac{5}{6} \\\\Through\ butterfly\ method\ of\ resolving\ the\ denominators\,\\\frac{(x+1)+x}{x(x+1)} = \frac{5}{6} \\\frac{2x+1}{x^2+x} =\frac{5}{6} \\6(2x+1)=5(x^2+x)\\12x+6=5x^2+5x\\\\Now, lets\ bring\ all\ the\ terms\ in\ the\ LHS\ to\ RHS.\\\\Hence,\\0=5x^2+5x-12x-6\\5x^2-7x-6=0\\[/tex]
By Factorizing the expression on the LHS. we get it equal to :-
[tex]5x^2-7x-6=0\\5x^2-10x+3x-6=0\\5x(x-2) + 3(x-2) = 0\\(5x+3)(x-2)=0[/tex]
Hence, we get two solutions for x, x=2, x= -3/5
As x is an integer, x=2 is the most suitable solution in this case.
Hence,
The numbers are 2,3
Which is the definition of a line segment
Answer:
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.
Step-by-step explanation:
Line segment is a line with two end points .
What is the line ?" Line is defined as the collection of points in one dimensional plane which has only one dimension length which extends to infinity."
According to the question,

A student cycles a distance of 63 km in less
than 3 hours. What is the average speed?
Answer:
About About 21 km/h
Step-by-step explanation: If they travel 63 km in 3 hours then all it is is just 63 divided by 3 or 63/3.
The average speed for the cycle will be 21 km per hour.
What is an average speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.
The average speed is defined as the ratio of the total distance traveled and the total time taken by the object.
Given that A student cycles a distance of 63 km in less than 3 hours. The average speed is calculated as:-
Average speed = Distance / time
Average speed = 63 / 3
Average speed = 21 km / hr

Find the points of Intersection of these graphs
y = x^2 and y = x +6
I need the explanation and how the formula is thanks Ill give 35 points
Answer:
the line crosses the parabola at (-2,4) and (3,9)
Step-by-step explanation:
y=x^2
y=x+6
set them equal to each other
x^2=x+6, now set it equal to zero
x^2-x-6=0, now find the root
(x+2)(x-3)=0, the x=-2, and x=3; now substitute into any of the equation to find the points where graphs intercept
at x= -2, y=(-2)^2=4, so one point is (-2,4)
at x=3, y=(3)^2=9, so other point is (3,9)
the line crosses the parabola at (-2,4) and (3,9)

36 is also the area of shape 2
Answer:
I think it is the area and perimeter are the same
Step-by-step explanation: Shape 1: If the perimeter is 26. one side is 9. 26-18= 8. You divide that to get the measure of the other side which is 4. 9*4=36. Shape 2: area is equal to 36, one side is for so the other side has to be 9. So the perimeter of shape 2 is 26 too.

80m of cloth are required to make 36 shirts. How many cloth required to make 45 shirts?
Answer:
80m --------> 36 shirts
x m ----------> 45 shirts
Thus by the unitary method, the value of x will be;
36 × x = 80 × 45
x = 80 × 9 × 5 / 36
x = 80×5/4
x = 20 × 5
x = 100 shirts.
