Jordan says that the shortest side
of any isosceles triangle has to be
at least 6 units, but Tierra says
there is no minimum length for the
shortest side of an isosceles
triangle. Who is right? Why?
Answer: I'm pretty sure Tierra is right because an isosceles triangle does not have a minimum side length. It's just the shortest length has to be equal to the other shortest length.
Step-by-step explanation: properties of an isosceles triangle.

Which ordered pair represents the reflection of the point (-4, 6) across both axes? O (4,6) O (4, -6) 0 (-4,6) O (-4,-6)
Reflecting across the Y axis, the y value stays the same and the X value become opposite:
(-4,6) would become (4,6)
Now reflecting across the X axis the x value remains the same and the Y value becomes the opposite:
(4.6) would become (4,-6)
Answer: (4,-6)

C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)
Write a simplified expression for C(x).
A. C(x) = -0.022x^3 + 9000x
B. C(x) = -0.018x^3 + 9000x
C. C(x) = -0.022x^3 + 15,000x
Answer:
B
Step-by-step explanation:
C(x) = (12,000x - 0.02x^3) - (3000x - 0.002x^3)
C(x) = 12,000x - 0.02x^3 - 3000)x + 0.002x^3
C(x) = (12,000 - 3,000)x + (-0.02 - 0.002)x^3
= 9000x - 0.018x^3

Answer:
30
Step-by-step explanation:
To work this out we do:
6÷20%
6÷0.2
30
This makes sense since 20% of 30 will be 10%(3) ×2 = 6
Answer:
30
Step-by-step explanation:
Equation ---> 6 = 20%
to get to 100% you multiply 20% by 5.
20% x 5 = 100%
So you do the same to the other side of that equation
6 x 5 = 30
6 is 20% of 30

PLS MARK AS BRAINLESS I MEAN BRAINLIEST
Step-by-step explanation:
Solve the system of linear equations by substitution.
x + 4y = 21
y = −x + 12
the solution to the system is ( , ) answer is an ordered pair
=========================================================
Explanation:
We can replace y in the first equation with -x+12 due to the second equation.
x+4y = 21
x+4( y ) = 21
x + 4(-x+12) = 21
x-4x+48 = 21
-3x = 21-48
-3x = -27
x = -27/(-3)
x = 9
which leads to,
y = -x+12
y = -9+12
y = 3
Therefore, the solution as an ordered pair is (x,y) = (9, 3)
---------------
Check:
x+4y = 21
9+4(3) = 21
9+12 = 21
21 = 21 .... the first equation works
and,
y = -x+12
3 = -9+12
3 = 3 ... so does the second equation
Both equations are true for those x and y values. The answer is fully confirmed.
Eve plays basketball. She makes 5 free throws for every 3 free throws that she misses. If she missed 36 free throws at her last practice, how many free throws did she make?
Answer:
60
Step-by-step explanation:
We can write a proportion to solve
5 made x made
------------ = -----------
3 missed 36 missed
Using cross products
5 * 36 = 3x
Divide each side by 3
5 * 36/3 = 3x/3
50 = x
She made 60

Why does a fraction with lesser denominator have larger pieces than the fraction with a greater denominator
Answer:
Step-by-step explanation:
The bigger the denominator the smaller the fraction.
For example if you have 1/9 and 1/5.
The fraction 1/5 has a greater denominator and is greater than 1/9, because it is split into less parts.

Answer:
In response to tissue injury, the body initiates a chemical signaling cascade that stimulates responses aimed at healing affected tissues. These signals activate leukocyte chemotaxis from the general circulation to sites of damage. These activated leukocytes produce cytokines that induce inflammatory responses [7].

Which equation represents exponential growth?
O A) y= 2x
O B) y = 3(5)
OC) y = 4x?
OD) y = 2(0.5)
Answer:
C) y = 4x?
Step-by-step explanation:
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change of a quantity with respect to time is proportional to the quantity itself.
There are two types of exponential functions: exponential growth and exponential decay. In the function f (x) = bx when b > 1, the function represents exponential growth. In the function f (x) = bx when 0 < b < 1, the function represents exponential decay
