Answer:
-3/8 = x
Step-by-step explanation:
90% sure this is correct but my simple math may be wrong
Answer: x=9
Step-by-step explanation:
x^2-8x-9=0...
we can simplify this by adding 9 to each side... so it turns into this: x^2-8x=9
Then, we can turn x^2 to x*x because we know that anything to the power of two is itself multiplied by itself. So our new equation will be this:
x*x-8x=9
Now we know x has to be 9 because 8 is 1 less than 9. Therefore, our answer would be x (9)...
Let’s test this out... first, let’s substitute x with the number 9:
9^2-8*9-9=0. Simplify this:
81-72-9=0. We can then simplify furthers and we get:
0=0. This means that the equation is true

b.2/12
c.2/16
d.1/12
Answers
Answer:
B) 2/12 basically 1/6 but not simplified
Step-by-step explanation:
so the probability of flipping heads is 1/2
The probality of rolling a number LESS than 3 is 2/6 becuase there are only 2 numbers less then 3 on a 1-6 cube.
now multiply them
1/2*2/6
2/12
so B
Julie works at a pizza place in Phoenix. She receives a 15% discount on any pizza that she buys. If a large pizza costs $14.00, what is the amount of Julie’s discount? What is the final cost of her pizza?
Answers
Answer:
The final cost of her pizza is $11.90
Step-by-step explanation:
First we need to convert 15% into a decimal, which is 0.15.
Now we multiply $14 and 0.15.
$14 × 0.15 = $2.10.
Now we subtract $2.10 from $14.00.
$14.00 - $2.10 = $11.90

Step-by-step explanation:
x=10
y=7.5
CE = 6
BD=4.5
Explanation:
Use similar triangles. Since you know one side length of the larger triangle, divide it by the hypotenuse of the smaller triangle to get the factor you are multiplying you side lengths by.
12.5 / 5
= 2.5
Multiply every other side length by 2.5
4 x 2.5 = 10
x = 10
3 x 2.5 = 7.5
y = 7.5
To get CE and BD subtract your values:
CE = 10 - 4
CE = 6
BD = 7.5 - 3
BD = 4.5

Identify The domain of the rational function, g(x)= 1/x+3
A (-∞, ∞)
B (-∞, 3)U(3, ∞)
C (-∞, -3]U[-3, ∞)
D (-∞, -3)U(-3, ∞)
Answers
Answer:
The domain is (-∞ , -3) ∪ (-3, ∞) ⇒ D
Step-by-step explanation:
The domain of the rational fraction is the values of x which make the fraction defined. That means the domain does not contain the values of x which make the denominator equal to 0.
∵ g(x) = [tex]\frac{1}{x+3}[/tex]
∴ The denominator = x + 3
→ Equate the denominator by 0
∵ x + 3 = 0
→ Subtract 3 from both sides
∴ x + 3 - 3 = 0 - 3
∴ x = -3
→ That means the domain can not have -3 because it makes the denominator
equal to 0
∴ The domain is all values of real numbers except x = -3
∴ The domain = {x : x ∈ R, x ≠ -3}
∴ The domain = (-∞ , -3) ∪ (-3, ∞)

If Triangle ABC ≈ Triangle DBE, find the value of x.
Answers
Answer:
x = 49
Step-by-step explanation:
The sum of angles in a triangle add up to 180°.
∠CBA = ∠EBD (Vertically opposite angles are equal)
= 52°
Since in the triangle DBE, you already know two of the angles, you can find ∠BDE which is equal to ∠CAB (x + 9)°.
∠BDE = 180° - 70° - 52°
= 58°
∠BDE = ∠CAB
= ∠(x + 9)°
= 58°
x + 9 = 58
x = 58 - 9
x = 49
