How can you determine which part of the triangle is the base and which is the height?
f(x)= -2x^2
what is the vertex of this and/or how do you find the vertex??
Answer:
(0,0)
Step-by-step explanation:
x value of vertex = -b/2a
ax^2+bx+c
-2x^2+0x+0 sinc you have no value of b & c in your quadratic function
-b = 0
2a = (2)(-2)
-b/2a = (0/-4) = 0
x value of the vertex = 0
plug 0 in for all values of x in the function to find y coordinate value
-2(0)^2 = 0
(x,y) = (0,0)

Which of these strategies would eliminate a variable in the system of equation?
2x+3y=-5
2x-3y=10
One of the strategies that would eliminate a variable in the system of equations is by subtracting both equations to eliminate the variable "x"
Eliminating variables from the system of equations?System of equations consists of a different set of equations with unknown variables.
Given the system of equations
2x+3y=-5
2x-3y=10
Since the coefficient of x from both equations are the same, we will subtract both equations to eliminate the variable "x"
(2x-2x)+(3y+3y) = -5 + 10
6y = 5
Hence we can conclude that one of the strategies that would eliminate a variable in the system of equations is by subtracting both equations to eliminate the variable "x"

Answer:
x = 8, y = 6/√3.
Step-by-step explanation:
The smaller triangle and the larger triangle are similar.
4 / 4√3 = (x - 6) / y
1/√3 = (x - 6) / y
Also
y/6 = 1/√3
⇒ √3y = 6
⇒ y = 6/√3
Substitute for y in the first equation:
1/√3 = (x - 6) / 6/√3
⇒ 1/√3 * 6/√3 = x - 6
⇒ x - 6 = 2
⇒ x = 8

There are a total of 165 dogs and cats waiting for homes at the Grand Strand Humane Society. The number of cats is 24 less than twice the number of dogs.
Part A: Identify both variables you are using, then write equations to represent both situations
Part B: How many dogs and cats are waiting to be adopted in the shelter? You must show work. Write your answer in the form of a sentence
Answer:
Part A
Let d = number of dogs
Let c = number of cats
Given:
total of 165 dogs and cats⇒ d + c = 165
Given:
The number of cats is 24 less than twice the number of dogs⇒ c = 2d - 24
Part B
Substitute c = 2d - 24 into d + c = 165 and solve for d:
⇒ d + 2d - 24 = 165
⇒ 3d - 24 = 165
⇒ 3d = 189
⇒ d = 63
Substitute found value of d into d + c = 165 and solve for c:
⇒ 63 + c = 165
⇒ c = 102
Therefore, 63 dogs and 102 cats are adopted in the shelter.

Answer:
Step-by-step explanation:
The student used the commutative property of addtion on the right hand side, which is correct because reordering the addends doesn't affect the value of the expression.
The student used additive commutative property for the first step.
What is an additive commutative property?According to this property, when two numbers or integers are added, the sum remains the same even if we change the order of numbers/integers. This property is also applicable in the case of multiplication. It can be represented as; a + b = b + a.
The student used a + b = b + a
3a + b = 2 + 7 - 5a = 2 - 5a + 7
Because add two numbers, exchange the position of the addend, and sum of them remain same.
This is a additive commutative property.

Here are two squares, A and B.
B
The length of the side of square A is 50% of the length of the side of square B.
Express the area of the shaded region of square A
as a percentage of the area of square B.
Answer:
The shaded region of A is 12.5% of the area of B.
Step-by-step explanation:
Although the side of square A is 50% of the side of square B, if you think about things logically here square A is only 25%of square B. Therefore the shaded area HAS to be half of 25% making the answer 12.5%
Answer:
12.5%
Step-by-step explanation:
Since it given that the length of the sie of a square A is 50% of the length of the side of square B. As well as given us the question we need to find the answer to which is:
Express the area of the shaded region of square A as a percentage of the area of square B.
What we need:
Area of shaded region of Square A as a % of Area of Square B
Now we can solve but first :
Let "b" be the side length of Square B
Let "a" be the side length of Square A
As well as:
It given side length of Square A (a) = 50% (1/2) of side length of Square B (b), therefore we have,
a = ½b
Area of a square = s², where s is the side length
Area of Square A = (½b)² = b²/4
Area of Square B = b²
Finding the area of the shaded region of the Square A = ½ of area of Square A.
Area of shaded region of Square A = ½*(b²/4) = b²/8
Expressing the area of the shaded portion of square A as a percentage of are of Square B:
Area of shaded portion of Square A ÷ Area of Square B × 100%
Solving:
⇒ [tex]\frac{\frac{b^2}{8}}{b^2}\times100[/tex]
⇒[tex]\frac{b^2}{8}\times\frac{1}{b^2}\times100[/tex]
⇒ [tex]\frac{b^2\times1}{8\timesb^2}\times100[/tex]
⇒ [tex]\frac{b^2}{8\times b^2}\times100[/tex]
⇒ [tex]\frac{1}{8}\times100=12.5[/tex]
Base on the solving above we can conclude that:
The area of the shaded region of Square A is 12.5% of the area of Square B.
