26-4s=9s
⇔26=9s+4s
⇔26=13s
⇔s=2
Answer:
s = 2
Step-by-step explanation:
26 - 4s = 9s
add 4s to 4s and 9s
that equals 13
26/13 = 13s/13
s = 2

PLEASE I NEED HELP I GOT A PUPPY AND IM EXHAUSTED HE DOESNT SLEEP AT NIGHT
Answer:
False
Step-by-step explanation:
It is false because the graph of [tex]y=x^{2}[/tex] does not passes through the point [tex](16,4)[/tex].
x = 16
y = 4
Substitute
[tex]4=16^{2}[/tex]
[tex]4=256[/tex]
Since 4 is not equal to 256, the answer is false.
Answer:
i hope this helps because i have a dog too and it is a husky that is one-years-old. oh and it is false
Step-by-step explanation:
4≠224. ∴The functions whose graphs include the point (16, 4) is y = x−12.
Use the substitution method for solve for x and y.
y = 2x + 10
y = -4x - 2
If θ is an angle in standard position whose terminal side lies in quadrant III and sin θ=-√3/2, find the exact value of the tan θ
Answer:
C) √3
tanθ = √3
Step-by-step explanation:
Step:-1
Given that θ be an angle in standard position whose terminal side
Given that the angle
sinθ = [tex]\frac{-\sqrt{3} }{2}[/tex]
Given that the Opposite side AB = [tex]\sqrt{3}[/tex]
Hypotensue AC = 2
Step(ii):-
By using Pythagoras theorem
AC² = AB² +BC²
BC² = AC² - AB²
BC² = 4 - (√3)²
= 4-3
BC = 1
Adjacent side(BC) = 1
Step(iiI):-
Given that 'θ' lies in the third quadrant so tanθ is positive
tanθ = [tex]\frac{AB}{BC} = \frac{\sqrt{3} }{1}[/tex]

Manny's muffins sells 50 muffins each day. 12 of these are blueberry. If they sell a 150 muffins tomorrow, how many blueberry muffins can they expect to sell?
Answer:
36 muffins
Step-by-step explanation:
[tex]\frac{12}{50} = \frac{x}{150}[/tex]
50 goes into 150 3 times so multiply 12 by 3 to get the value of x
12 · 3 = 36

Indicate whether the function represents an exponential growth or decay.
Answer:
1) decay
2) growth
3) growth
Step-by-step explanation:
A generic exponential function can be written as:
f(x) = A*(r)^x
Where:
A is the initial amount of something.
r is the rate of growth.
x is the variable, usually, represents time.
if r > 1, we have an exponential growth.
if r < 1, we have an exponential decay.
1) f(x) = (3/4)^x
in this case we have:
A = 1
r = (3/4) = 0.75
Clearly, r < 1.
Then this is an exponential decay.
2) f(x) = (1/6)*4^x
In this case we have:
A = (1/6)
r = 4
Here we have r > 1.
Then this is an exponential growth.
3) f(x) = (1/4)*(5/2)^x
in this case we have:
A = 1/4
r = 5/2 = 2.5
here we have r > 1, then this is an exponential growth.
Find the value of x in each diagram.
Answer:
4. 25 5. 80 6. 30
Step-by-step explanation:
All triangles add up to 180.
The triangle in #4 is right, so 90° + 65° = 155°
180° - 155° = 25°
x=25
#5.
50° + 50° = 100°
180° - 100° = 80°
x=80
In #4 the triangle is an equilateral, so all the angles will be equal. 2x + 2x + 2x = 180
6x = 180
x = 30
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
Two of the angle measures are given in each triangle so to find the third angle measurement we need to subtract the sum of two of the interior angles
4.
180 - (65 + 90) = x
180 - 155 = x
25 = x
5.
180 - (50+5) = x
180 - 100 = x
80 = x
For the 6th question all side lengths are equal so the angle measures also equal and 60 each
2x = 60
x = 30

Step-by-step explanation:
The equation for area of a triangle is base times height divided by two.
Which equation describes the function in the table below?
Answer:
A
Step-by-step explanation:
So, first we have to eliminate answers, let us check A first. If we simplify this equation, it's basically saying Y is equal to 1.3 times X plus 10. So, 0 x 1.3 = 0 plus 10 = 10. Now we check the rest of the table. 5 x 1.3 = 6.5 + 10 = 16.5. 10 x 1.3 + 10 = 23. 15 x 1.3 + 10 = 29.5, and 20 x 1.3 = 26 + 10= 36. The math matches with the table so we're done.

What are 2 factors of 72y + 108z?
What is the actual height of the building shown in the model?
Answer:
The actual height is 150ft
Step-by-step explanation:
Given
[tex]Width : Height = 2cm : 5cm[/tex]
[tex]Actual\ width = 60ft[/tex]
Required
Determine the actual height
Substitute 60ft for width in: [tex]Width : Height = 2cm : 5cm[/tex]
[tex]60ft:Height =2cm:5cm[/tex]
Express as fraction
[tex]\frac{60ft}{Height} =\frac{2cm}{5cm}[/tex]
[tex]\frac{60ft}{Height} =\frac{2}{5}[/tex]
Make height the subject
[tex]Height = \frac{5}{2} * 60ft[/tex]
[tex]Height = 5 * 30ft[/tex]
[tex]Height = 150ft[/tex]
Answer:
Step-by-step explanation:
1 cm represents 30 ft
height of building = 5 cm × 30 ft/cm = 150 ft
