Answer:
y=(x-2)(x+2)
Step-by-step explanation:
The table and graph show the line crossing the x axis at -2 and +2. That means when x is either of those two values, y will be 0.
If we set each equation to zero, we should find those two values of x. I'll skip right to the second equation, since I can see that it would meet those criteria:
y=(x-2)(x+2)
0=(x-2)(x+2)
x = 2 and x = -2

Answer:
36
Step-by-step explanation:
7x+4 = 15x-12
7x = 15x-16
-8x = -16
-8x/-8 = -16/-8
x = 2
BD = 15x-12 + 9x
BD = 15(2)-12 + 9(2)
BD = 30-12 + 18
BD = 18 + 18
BD = 38

Answer:
72°
Step-by-step explanation:
Angle B is the same as angle C in this isosceles triangle. The sum of the angles is 180°, so you have ...
x + 2x +2x = 180°
x = 180°/5 = 36°
∠ABC = 2x = 2(36°) = 72°
Which inequality represents all values of x for which the quotient below is
defined?
Answers
Answer:
Option B: x > 0
Step-by-step explanation:
Option A is wrong because [tex]\sqrt{3(0)}[/tex]will be 0. So, the inequality can't be divided by 0.
Option C is wrong because 1 will suffice this inequality. [tex]\sqrt{7}/\sqrt{3}=1.5 (approx)[/tex]
Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).
Leaving us with only option B, which is the right answer.
The inequality x > 0 represents all values of x for which the quotient √(7x²) ÷ √(3x) is defined.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To determine the values of x for which the quotient √(7x²) ÷ √(3x) is defined, we need to ensure that the denominator is not zero.
Since the denominator contains √(3x), we know that 3x must be positive for the expression to be defined.
So, the inequality 3x > 0 for x.
Dividing both sides by 3, we get x > 0/3, which simplifies to x > 0.
Therefore, the correct answer is (B) x > 0, which represents all values of x for which the quotient.

Write the equation of the line that is perpendicular to the line given and through the given point. Do not use spaces in your equation. y=-x-3 (-1, 4) *
Answers
Answer:
y=x+5
Step-by-step explanation:
The equation is given in slope-intercept form, so we can read the slope from the equation. It is the x-coefficient, -1.
The slope of the perpendicular line will be the opposite reciprocal of this value:
-1/-1 = 1
The new y-intercept will be ...
b = y -mx = (4) -(1)(-1) = 5
Then the slope-intercept equation of the perpendicular line is ...
y = x +5

One booster pack is worth 9 cards and one premade deck is worth 37 cards.Step-by-step explanation:
We know that:
9x + 7y = 340 cards4x + y = 73 cardsy = Cost of premade decks (In cards)x = Cost of booster packs (In cards)Work:
9x + 7y = 340 cards4x + y = 73 cards
4(9x + 7y = 340 cards)9(4x + y = 73 cards)
36x + 28y = 340 x 4 cards36x + 9y = 73 x 9 cards
19y = 1360 - 65719y = 703y = 703/19 = 37This means that 1 premade deck is worth 37 cards. Now, let's substitute the value of y into the first equation to find x.
9x + 7y = 340 cards=> 9x + 7(37) = 340 cards=> 9x + 259 = 340 cards=> 9x = 81 cards=> x = 9 cardsHence, one booster pack is worth 9 cards and one premade deck is worth 37 cards.

The graph of a proportional relationship contains the point (20, 4) .
What is the corresponding equation?
please hurry i need help ill give 100 points
Answers
Step-by-step explanation:
in a proportional relationship, one variable is always a constant value times the other.
and as such, (0, 0) is always a point of that relationship too.
in general that means the equation is
y = ax
with a being the constant.
using the given point :
4 = a×20
a = 4/20 = 1/5
so, the equation is y = x/5

3h + 2 - 6 + 5h and 2( 4h -2)
Answers
Answer:
here
Step-by-step explanation:
when given the first set, you combine like terms so you add 5h and 3h together and -6 and 2 are combined, so the first one is 8h -4. The second set you distribute 2 to 4h and -2 getting you 8h and -4 as well
Answer:
See explanation
Step-by-step explanation:
Let’s manipulate 3h+2-6+5h to show how it is equal to 2(4h-2)
Combine like-terms:
3h+2-6+5h = 8h-4
Then, factor out the greatest common factor (in this case it’s 2):
8h-4 = 2(4h-2)
If you want to verify how to above is true, just combine them again!
