Answer:
Yes, because 1 & 2 have to be the same
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Supplementary means 180 degree.
∠1 + ∠3 = 180 ----> eq. 1
∠2 and ∠3 are linear pair angles which are also supplementary.
∠2 + ∠3 = 180 ----> eq. 2
∠3 = 180 - ∠1 ----> eq. 3
( from eq. 1 )
∠3 = 180 - ∠2 ----> eq. 4
( from eq. 2 )
From, eq. 3 and eq. 4,
180 - ∠1 = 180 - ∠2
Subtract 180 on both sides.
180 - 180 - ∠1 = 180 - 180 - ∠2
- ∠1 = - ∠2
Multiply - 1 on both sides,
∠1 = ∠2
Since,
∠1 = ∠2
Sides opposite to them also equal
So, AC = BC
If any two sides in a triangle is equal, then the triangle is an isosceles triangle.
Therefore,
Δ ABC is isosceles.
What is the value of s?
____units
Answer:
[tex]\huge\boxed{s=17}[/tex]
Step-by-step explanation:
ΔADB is the right triangle with a right angle in vertex B. We can use the Pythagorean theorem.
[tex]leg^2+leg^2=hypotenuse^2[/tex]
We have:
[tex]leg=15\\leg=8\\hypotenuse=s[/tex]
Substitute:
[tex]s^2=15^2+8^2\\\\s^2=225+64\\\\s^2=289\Rightarrow s=\sqrt{289}\\\\s=17[/tex]

Age old help!!!!!!
…….
Answer:
Zoe was 32 years old, which was 4 years ago.
Step-by-step explanation:
When Zoe was 36 years old, her daughter was 1/3 her age, or 12 years old. Therefore, the difference in ages is 24 years.
So, our equation becomes:
4(Z-24) = Z
4Z - 96 = Z
3Z = 96
Z = 32
Assuming Zoe is 36 years old right now, our answer is 4 years ago.
Hope this helped,
~cloud
Since the daughter is 1/3 Zoe's age, she must be 12 since 1/3 of 36 is 12.
Then make a chart like I have done in the image attached.
Since the problem says "how many years ago", we use
our x years ago column in our chart to setup the equation.

Answer:
false
Step-by-step explanation:
If it was at least 2, it would show x>= 2 which includes 2. However, that question doesn't include 2 so if it is true, it would have said "X is greater than 2"
Answer: False
Step-by-step explanation: When x is at least 2, x would be greater than or equal to 2. X cannot be less than 2. So, it should be x >= 2.

A) 78.5 cm
B) 4.7cm
C) 5.8cm
D) 23.0 cm
Answer:
The answer to this would be B.) 4.7 cm
Step-by-step explanation:
Arch = (Angle/360)(2[tex]\pi[/tex]r)
= (45/360)(2[tex]\pi[/tex]6)
= (0.125)(12[tex]\pi[/tex])
=1.5[tex]\pi[/tex]
≈4.71cm (assuming [tex]\pi[/tex] = 3.14)
Since an arch of a circle is just part of the circumference, you just need to multiply the circumference by the measure of the arch's angle divided by 360 (the angle measure of a circle).
the sum of three consecutive numbers is five times the difference of the middle number and 22. find the numbers.
Let n be the smallest of the three numbers. Then
n + (n + 1) + (n + 2) = 5 ((n + 1) - 22)
Solve for n :
3n + 3 = 5 (n - 21)
3n + 3 = 5n - 105
2n = 108
n = 54
Then the three numbers are 54, 55, and 56.

Function ris a continuous rational function with a horizontal asymptote at y = -8.
Which statement describes the key features of s(t) = (x +2) – 12
A. Function s is continuous and has a horizontal asymptote at y = -1.
В. Function shas a point of discontinuity at I = -2 and a horizontal asymptote at y= -9.
C. Function s has a point of discontinuity at r = -2 and a horizontal asymptote at y = -1.
D. Function sis continuous and has a horizontal asymptote at y = -9.
s(x) is continuous and has a horizontal asymptote at y = -9
We know that we have a function r(x) that has a horizontal asymptote at y = -8
Then, what can we say about the function s(x) = r(x + 2) - 1 ?
Ok, first remember that a horizontal asymptote means that as x, the variable, increases (or decreases), the function eventually tends to a given value, but never actually reaches it.
So as x tends to infinity, we should see an almost horizontal line that tends to y = -8.
So if that happens when x tends to infinity, the same thing will happen when x + 2 tends to infinity, because that "+2" does not add a lot.
Then is easy to conclude that:
r(x + 2) also has a horizontal asymptote at y = -8
And our function is:
s(x) = r(x + 2) - 1
So we are subtracting one, then that horizontal asymptote will be at:
y = -8 - 1 = -9
The function s(x) has a horizontal asymptote at y = -9
And because r(x) is continuous, then:
s(x) = r(x + 2) - 1
is also continuos, as there is nothing added that could change the continuity (we do not have any zero in the denominator or something like that)
Then the correct option is D.
"s(x) is continuous and has a horizontal asymptote at y = -9"

Jack rides his bike 4 miles in 1/3 of an hour. What is jack unit rate in miles per hour?
Answer:
12 miles
Step-by-step explanation:
1/3 of an hour = 20 minutes = 4 miles
1 minute = 4/20 miles
60 minutes = 4/20 x 60 miles
= 4 x 3 miles
= 12 miles
60 minutes = 1 hour
=> 1 hour = 12 miles
Jacks unit rate is 12 miles/hr
Answer:
12
Step-by-step explanation:
There are two ways of doing this problem. I think the easiest way is to use a decimal in the denominator and round
4/0.333333333 = 12.000000001
The answer is obviously meant to be 12.
The other way is more sophisticated, but more accurate.
4/1 // 1/3 This is a 4 tier fraction. The rule is to invert the denominator (turn the bottom fraction upside down) and multiply.
4/1 * 3/1 = 12
The first method is easier to understand. The second is more accurate and more useful for physics.

Answer:
f(x) = 3.33x - 7
Step-by-step explanation:
We are suppposed to write the slope intercept form of the line . The slope intercept form of the line is ,
[tex]\rm\implies y = mx + c [/tex]
where ,
m is slopec is y intercept .Here we can see that the line is passing through (0,-7) . Therefore ,
[tex]\rm\implies y- intercept = -7[/tex]
Also we can see that the line is passing through (2.1,0) . Therefore we can find the slope as ,
[tex]\rm\implies Slope =\dfrac{y_2-y_1}{x_2-x_1}\\\\\rm\implies Slope =\dfrac{ -7-0}{0-2.1}\\\\\rm\implies \bf Slope = 3.33 [/tex]
Using Slope Intercept Form :-
[tex]\rm\implies y = mx + c \\\\\rm\implies y = 3.33x + (-7) \\\\\rm\implies\underline{\boxed{\rm\blue{f(x) = 3.33x - 7 }}}[/tex]

Answer:
x = 13.75
Step-by-step explanation:
a right-angled triangle.
so, we use Pythagoras
c² = a² + b²
where c is the Hypotenuse (the side opposite of the 90 degree angle).
so, in our case
17² = 10² + x²
289 = 100 + x²
189 = x²
x = 13.75
Tanya has a garden with a trench around it. The garden is a rectangle with a length of 2 1/2 m and width 2 m The trench and garden together make a rectangle with length 3 1/2 and width 3m
Find the area of just the trench.
Answer:
Area of the rectangular trench = 1 square meter
Step-by-step explanation:
length of the garden = 2 1/2 m width of the garden = 2 m
length of both garden and trench = 3 1/2 m
width of both garden and trench = 3m
Length of the trench = Difference in length
= 3 1/2 m - 2 1/2 m
= 7/2 - 5/2
= (7 - 5) / 2
= 2/2
= 1 m
Length of the trench = 1 m
Width of the trench = difference in width
= 3 m - 2 m
= 1 m
Width of the trench = 1 m
Area of the rectangular trench = length × width
= 1 m × 1 m
= 1 m²
Or
1 square meter
Area of the rectangular trench = 1 square meter

Find the range of f(x) = 5x - 4 for the domain = {2, 4, 6}]
Answer:
Step-by-step explanation:
For this question they are asking you to find y when x is {2, 4, and 6}
That means you need to plug 2,4, and 6 into the equation and solve.
For example:
f(x) = 5x - 4
f(2) = 5(2) - 4
f(2) = 10 - 4
f(2) = 6
f(x) = 5x - 4
f(4) = 5(4) -4
f(4) = 20 - 4
f(4) = 16
f(x) = 5x - 4
f(6) = 5(6) - 4
f(6) = 30 - 4
f(6) = 26
Answer:
