Solve for the roots in simplest form using the quadratic formula:
x^2 + 61 =-10x
9514 1404 393
Answer:
-5 ± 6i
Step-by-step explanation:
To use the quadratic formula, we need the equation in standard form. Adding 10x gives ...
x^2 +10x +61 = 0
Then a=1, b=10, c=61, and the solutions are ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-10\pm\sqrt{10^2-4(1)(61)}}{2(1)}\\\\=\dfrac{-10\pm\sqrt{-144}}{2}=\dfrac{-10\pm12i}{2}\\\\ \boxed{x=\{-5-6i,-6+6i\}}[/tex]

I would give you the answers but then that wouldn't help you, so sorry in advance.
We already know that the slope of a line is rise over run
or y1-y2/x1-x2
But that only gives us the slope
What if we want to have an equation that shows what points it passes through as well
Well, that's basically what slope-intercept is.
We can use this simple formula (simple because there's much more complicated formulas)
y=mx+b where y equals the y coordinate, x equals the x coordinate, m equals the slope, and b is the y-intercept.
As an example, I'll do the first one for you.
y=mx+b
Plug in what we know
y=1x+4
You can simplify this down to
y=x+4, since 1 is identity property.
Then, you make up what x is, and your like "x is 0", if x=0, then y=4, so it'll work like that, but I'm pretty sure you don't have to show that.
And as a treat, I'll do the second one as an example:
y=mx+b
Plug in what we know
y=2x+(-2)
Simplify
y=2x-2
Same thing here, you make up what x is, and your like "x is 0", if x=0, then y=4, so it'll work like that, but I'm pretty sure you don't have to show that.
Hope this helps, let me know if you have any questions,

If line A has a slope of 7/8, what is the slope of line B that is perpendicular to
line A
Answer:
8/7
Step-by-step explanation:
There is a line that includes the point (5, 6) and has a slope of 0. What is its equation in
slope-intercept form?
Answer:
y = 0x +6 or y = 6 if simplified
Step-by-step explanation:
y=mx+b is slope intercept formula
m is the slope which we know ( 0 ) and we know the line passes through (5,6) so all we need to figure out is b
so plug it in and solve:
6 = 0(5) +b
6 = b
so 6 is b and now we know the equation
y = 0x +6 or y = 6 if simplified
Larissa dives into a pool that is 8 feet deep. She touches the bottom of the pool with her hands 6 feet horizontally from the point at which she entered the water. What is the approximate angle of elevation from the point on the bottom of the pool where she touched to her entry point? 36.9° 41.4° 48.6° 53.1
The approximate angle of elevation from the point on the bottom is; D: 53.1°
What is the angle of elevation?We are told she dived into a pool that is 8 ft deep.
Now, she could touch the bottom with her hands 6 ft horizontally. Thus;
We can use trigonometric ratio to determine the approximate angle of elevation from the point on the bottom of the pool where she touched to her entry point.
If the angle of elevation is θ, then we have;
θ = tan⁻¹(8/6)
θ = 53.1°

One sixth of the candies in a bag of M&M's are
orange. If there are 15 orange candies, how many
M&M's are in the bag?
Answer:
90 candies
Step-by-step explanation:
15/ 1/6=90
90*1/6=15
Answer:
90
Step-by-step explanation:
Let x = number of M&M's in the bag
(1/6) * x = 15 [in word (story) problems, "of" usually means multiply]
x = 90 [multiply both sides by 6]

Jeff traveled at an average speed of 65 miles per hour for 2.5 hours and then traveled at an average speed of 70 miles per hour for 1.5 hours. What was the total distance in miles that Jeff traveled during this time?
Answer:
267.5 miles
Step-by-step explanation:
We start with the formula for speed:
speed = distance/time
Now we solve it for distance:
distance = speed * time
65 mph for 2.5 hours + 70 mph for 1.5 hours
distance = 65 * 2.5 + 70 * 1.5
distance = 162.5 + 105
distance = 267.5
Answer: 267.5 miles

Write the prime factorization of 20.Use exponent when appropriate and order the factor from least to greatest
Answer:
20 = [tex]2^{2}[/tex] x 5
Step-by-step explanation:
From the general knowledge, prime numbers have two factors. Therefore, prime factorization of 20 implies prime numbers that are factors of 20. This involves expressing a given number in its prime factor.
So that the prime factors of 20 can be expressed as,
20 = 2 x 2 x 5
= [tex]2^{2}[/tex] x 5
Thus, the prime factorization of 20 is [tex]2^{2}[/tex] x 5.

chicken tenders or chicken nuggets
Answer:
i dont know which one to choose but chicken tenders
Answer:
Chicken tenders.
Step-by-step explanation:
Chicken nuggets are the gross consumption of organs including lungs and others mushed together and fried. In return kids run to it because (most) kids only eat gross stuff. This made the marketing campaign SKY ROCKET with kids everywhere trying to get a bite. FORCING their poor parents to get them that disgusting mush. And then dip it in ketchup. Which is NOT a fruit or veggie. (As the school system thinks they are a veggie.)
While chicken tenders are chopped off the chicken meat then rolled in bread crumbs. And then deep fried to make a crispy exterior with a delicious tender interior. Without getting mushed together with other things.
Also you never know what they put in that chicken nugget since its mushed together ♀️.

The first fire tower is located 5 km east and 8 km south of the center, and the second fire tower is located 7 km west and 4 km north of the center. The technology at the first tower can locate fires within a radius of 10 km and the second tower within a radius of 9 km. The system of inequalities represents this scenario.

what is 2 8/15+ 1 1/30
Answer:
3 17/30
Step-by-step explanation:
In order to do this problem, we have to get the two fractions to have the same denominator
So we change 2 8/15 into 2 16/30 (multiplying both the numerator by 2, if you don't know why this works then ask me) and then we just add. So 2 16/30 + 1 1/30 = 3 17/30
Solve 7(3 − p) − p ≥ 8p + 5 for p.
Answer:
p ≤ 1
Step-by-step explanation:
Given
7(3 - p) - p ≥ 8p + 5 ← distribute left side and simplify
21 - 7p - p ≥ 8p + 5
21 - 8p ≥ 8p + 5 ( subtract 8p from both sides )
21 - 16p ≥ 5 ( subtract 21 from both sides )
- 16p ≥ - 16
Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity
p ≤ 1
A 37-foot ladder is leaning against a building. The angle between the ladder and the top of the building is 21. How far up the building does the ladder reach? Round to the nearest tenth.
Answer:
34.5 feets
Step-by-step explanation:
Length of ladder = 37 feet
Angle between ladder and top of building = 21°
Since ladder makes a right angle with the foot of the wall;
Angle the ladder makes with the ground :
(90° + 21° + θ) = 180°
111° + θ = 180°
θ = 180° - 111°
θ = 69°
To obtain the height, x of the building reached by the ladder ;
Using Pythagoras :
Sinθ = opposite / hypotenus
Sin 69° = x / 37
x = 37 * sin 69°
x = 37 * 0.9335804
x = 34.542475
x = 34.54 feets
Hence, the height up the building reached by the ladder is 34.5 feets
Use a vertical format to subtract the polynomials.
3x2 - 2x + 2
- (7x2 + 2x - 3)
Answer:
Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]
Step-by-step explanation:
We need to u se a vertical format to subtract the polynomials.
The polynomials given are:
[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)[/tex]
Now, solving
For, subtraction, the sign of the terms [tex]7x^2 + 2x - 3[/tex] will be changed. - will convert to + because (-)(-) = + and positive sign will be converted to negative (-)(+) = -
The sign with the resulting term will be the sign of term that has greater coefficient. For example if we are subtracting 3x^2 and (-7x^2), the result will be -4x^2 because 7 has negative sign. (term has greater coefficient)
[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)\\\\:\:\:\:\:\:\:-\:\:\:\:-\:\:\:\:\:+\\-----------\\-4x^2-4x+5[/tex]
So, Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]
M is the midpoint solve for x
Answer:
x = 3
Step-by-step explanation:
5x + 9 = 24
5x = 24 - 9
5x = 15
x = 3
Check:
5(3) + 9 = 24
SM = 24, MT = 24 ✔️
Answer:
Step-by-step explanation:
If M is the midpoint between points S and T, then both sides; SM and ST are equal. This means that 5x + 9 has to equal 24.
5x + 9= 24
5x +9 - 9= 24 - 9
5x= 15
5x / 5 = 15 / 5
x = 3
ANSWER: x = 3
