Solve the following equation by the quadratic formula. x 2 + x - 1 = 0
Answer
x is 1.62 or -0.62
Step-by-step explanation:
Quadratic Formula:
[tex] \boxed{ \bf{x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}}}[/tex]
Given Quadratic Equation:
x² + x - 1 = 0
a = 1 (Quadratic coefficient)
b = 1 (Linear coefficient)
c = -1 (Constant coefficient)
By substituting values in the formula, we get:
[tex] \rm \longrightarrow x = \dfrac{-1 \pm \sqrt{1^2 - 4(1)( - 1)}}{2 \times 1} \\ \\ \rm \longrightarrow x = \dfrac{ - 1 \pm \sqrt{1 + 4} }{2} \\ \\ \rm \longrightarrow x = \dfrac{ - 1 \pm \sqrt{5} }{2} [/tex]

120/160=15/y
(fractions)
please help me :(
Answer:
Y = 20
Step-by-step explanation:
120/ 160 = 15 / y
120/15=8
that means there is a 8 to 1 ratio between them. So now do 160/8 = y
y = 20.
prove it by dividing both fractions to create decimal form. They match, so y = 20.
Students are making ornaments and each takes 1/4 of a piece of Bristol board. They go to the cupboard and find 2 1/2 pieces of Bristol board. How many ornaments can they make?
Answer: 10 ornaments
Step-by-step explanation:
From the question, we are informed that students are making ornaments and each takes 1/4 of a piece of Bristol board. We are further told that they go to the cupboard and find 2 1/2 pieces of Bristol board.
The number of ornaments that they make will be gotten by dividing 2 1/2 by 1/4. This will be:
= 2 1/2 ÷ 1/4
= 5/2 ÷ 1/4
= 5/2 × 4/1
= 10
They can make 10 ornaments

(9+7i)+(-5-31) =
add complex numbers
Answer:
4 + 4i
Step-by-step explanation:
Add the real part and add the imaginary part.
9 + 7i + (-5 - 3i) = 9 + 7i - 5 - 3i
= 9 - 5 + 7i - 3i
= 4 + 4i
Answer:
44
Step-by-step explanation:
Okay so we are given (9 + 71) + (-5 - 31).
We need to figure out the value of this expression.
First, let's solve the expression (9 + 71).
1. (9 + 71) = 80.
Now we have 80 + (-5 - 31).
Next, let's solve the expression (-5 - 31).
2. (-5 - 31) = -36.
We're left with 80 + (-36).
Finally, let's add the two numbers together.
80 + (-36) = 44
So (9 + 71) + (-5 - 31) = 44

Answer:
angle A is congruent to angle R
Step-by-step explanation:
when it gets rotated counterclockwise around point X that is how the triangles end up matching up
Answer:
The answer is 1. ∠A ≅ ∠R
Step-by-step explaation:
Looking at the triangles when they're in their alphabetical order, ΔABC and ΔRST, since they are congruent, that means that if you were to pick an angle in one triangle, it would be equal to the angle in the same place of the other triangle. So if we were to take the first letter from ΔABC it'd be A, and the first letter in ΔRST is R, so that means angles ∠A and ∠R should be congruent.

What is coordinate?A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more integers, or coordinates. It matters how the coordinates are arranged.
Sometimes they are recognised by their place in an ordered tuple, and other times they are recognised by a letter, such as "the x-coordinate." In elementary mathematics, the coordinates are assumed to be real numbers. Point A t represents (3, - ).
Therefore, the correct option is option A.

Answer:
F, T, T, T, T, F
Step-by-step explanation:
PM and PN are "midlines" of the triangle JKL. As such, they are parallel to and half the length of the side of ΔJKL they don't intersect. The relationships of angles and transversals of parallel lines apply. LMPN is a parallelogram, so opposite sides are the same length.
a) JL is not 36, it it twice that. (F)
b) ML is the same length as PN, 36. (T)
c) MP is half of LK, so is 97/2 = 48.5. (T)
d) ∠JLK corresponds to ∠JMP, so is congruent. (T)
e) ∠PNK corresponds to ∠JLK, so is congruent. (T)
f) MP intersects PK at point P, so cannot be parallel. (F)

The populations of Cities A and B are 1.6 x 10^5 and 1,070,000, respectively. The population of City C is twice the population of City B. The population of City C is how many times the population of City A?
Answer:
13
Step-by-step explanation:
First find the population of city c 1,070,000 times 2 = 2140000
Round 2140000 to the nearest hundred thousands = 2,100,000
Third find how many places the decimal moves which is 6 places
Fourth scientific notation of 2,100,00 is 2.1 times 10^6
Fifth divided city c by the population of city a
2.1x 10^6 divided by 1.6 x 10^5
2.1 / 1.6 rounded is 1.3
10^6 divided by 10 ^ 5 is 10
Therefore 2.1 x 10^6 divided by 1.6 divided by 10^5 equals 1.3 times 10 = 13
The population of city c is about 13 times the population of city a

What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
A squirrel runs across a road in 3 seconds.
The road was more than 34 feet wide.
1. The Squirrel's speed is
3r > 34
2. The solution of the inequality is
r > 34/3
r > 11.3
3. The interpretation is: The squirrel ran faster than 11.3 feet per second.

write 28 + 24 as a product of two factors using the GCF and the distributive property
Answer:

Step-by-step explanation:
GCD of 28 and 24 is 4
28 = 4 x 7
24 = 4 x 6
u take the 4 out
4 (7 + 6)
4 x 13
The product of two factors using the GCF and the distributive property is 4(13).
What is the meaning of the greatest common divisor/factor?
The largest integer of highest degree that is an exact divisor of each of two or more integers.
The greatest common divisor of 24 and 28
24=2×2×2×3
28=2×2×7
We can see that the 2 and 2 is common in 24 and 28
The GCD of 28 and 24 is=2×2= 4
For the distributive property we have
28 = 4 x 7
24 = 4 x 6
we take the 4 out
