Answer:
33 texts
Step-by-step explanation:
34.99+0.15(t)=40
lets say t is number of texts
subtract 34.99 from both sides
0.15(t)=$5.01
divide 5.01 by .15
33.4
but you cant send .4 of a text
so 33 texts

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
That's the final answer.

HURRY!! A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. What is the rate of change.
Answer:
175ft an hour
Step-by-step explanation: lets say t=hours
so 2t=400ft and 6t=700ft
the difference between hours is 4 because 6-4=2
so we would multiply 4 by ?
to get the missing # you would have to multiple 4 by numbers between 170 and 190 because anything under 170 is no where near 175 and anything above 190 is way off 175. Answer is 175ft per hour
Answer:
total distance =700+400ft
time =2+8 =10hour
rate =distance/time=1100/10=110 ft/hour
since he stops two times
rate of change =110/2=75ft/hour

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.
Answer:
100m
Step-by-step explanation:
80/36= takes 2 2/9 or 20/9 to make one shirt
20/9*45 shirts=100m

Could someone please do this for me
Answer:
the shapes below are similar because,
Step-by-step explanation:
36 divided by 4 is 9.
9 is also the length on shape 2.
(9x2) + (4x2) = 36
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.

-8а - 5 = 3 - 6а
Answer:
-8a-5=3-6a
-8a+6a=3+5
-2a=8
a=8/-2
therefore,a=-4 answer...
Answer:
a = 4
Step-by-step explanation:
Firstly, make all subtraction signs, addition signs which should look like this
-8a + -5 = 3 + -6a
Add 5 to both, -5 and 3.
-8a = 8 + -6a
Add 8a to both -8a and -6a

Is the domain of the function represented by the data shown in the graph discrete or continuous?
9514 1404 393
Answer:
continuousdistance traveled by walkingStep-by-step explanation:
You can draw the graph without lifting your pencil, so it is "continuous."
Rows, drinks, and books are all things that are counted. That is, their number takes on discrete values.
Time, on the other hand, is continuous--able to take on any value.
The graph best models distance as a function of time.
Which graph below represents a function?
Draw a vertical line and notice if the vertical line intercepts more than 2 points in the graph.
A, if we draw a vertical line, it'll just intercept only one point of the graph. So A is function.
A is the only function here. If we draw a vertical line for other graphs, it'll intercept 2 points.
