D=2^2-4*(-4)*5=4+80=84
x1,2 = (-2±√(84))/10
x1= (-2+√(84))/10 = (-2+√(4*21))/10 = (-2+2√(21))/10 = (-2(1-√(21))/10 = -(1-√(21))/5

Question 6 of 10
What is the most logical first step in solving the equation x2 +6x+9 - 10?
A Factor the left side of the equation
B. Subtract 10 from both sides of the equation
C. Take the square root of both sides of the equation
D. Subtract 9 from both sides of the equation
SUBMIT
Answer:
A.factor the left side of the equation
sorry but to tell u the answer, I need to know this
is there an equal sign between 9 and 10 or it's just a minus sign?
I mean if it is a minus sign the first thing to do to solve the equation is 9-10 which gives you -1. but if there is an equal sign the first step is to subtract 10 from both sides of the equation which means your answer will be option B.

Answer:
80°
Step-by-step explanation:
the triangles are symmetrical. therefore their angles will be equal.
interior angles of a triangle = 180°
180° - 30° - 70° = m<D
80° = m<D
You are arranging 60 pictures on a poster board. the board can fit up to 4 rows of pictures and each row can have up to 20 pictures. you want each row to have the same numbers of pictures. how many different ways can you arrange the pictures?
Answer:
2 different ways
Step-by-step explanation:
You are looking at the factors of 60.
1×60 does not work, too many pictures in a row.
2×30 does not work, too many pictures in a row.
3×20 THIS WORKS!
4×15 THIS ALSO WORKS!
5×12 Nope, too many rows
6×10, no, too many rows
So there's just two ways to arrange the pictures.

I NEED HELP WITH THIS MATH I DONT GET IT!!!!!
Answer:
It's 5
Step-by-step explanation:
-4x+5=-15 (subtract 5)
-4x=-20 (divide by -4)
x=5
Step-by-step explanation:
Work backwards. First, create a function:
f(x) = x
First, instead of adding 5, subtract it:
f(x) = x - 5
Then, divide by -4:
f(x) = (x - 5) ÷ -4
Then plug in -15:
f(-15) = (-15 - 5) ÷ 4
= -20 ÷ -4
= 20 ÷ 4
= 5

write the equation of the line?
Answer: Yellow option
Step-by-step explanation:
The points noted are (0,-2) and (3,-1)
So the slope is (-2--1)/(0-3) = -1/-3 = 1/3
So options blue, green and red are out.
So the only option is yellow
en una bolsa hay menos de 30 semillas. podemos hacer grupos de 4 semillas sin que sobre ninguna. si hacemos grupos de 5 semillas tampoco sobra ninguna. ¿Cuántas semillas hay en la bolsa?
What percentage of the apples are green?
Answer:
6 of the 30 apples are green
6 / 30 = .2
So 20% of the apples are green.
Percentage of the apples are green is 20%
What is a percentage?
"A Percentage is a number or ratio that represents a fraction of 100. It is often denoted by the symbol %".
According to the question
Total Apples = 30
Red Apples = 24
Green Apples = 6
Percentage of the apples are green = [tex]\frac{6}{30}[/tex]×[tex]100[/tex]
= [tex]20[/tex] % or [tex]0.2[/tex]
∴ Percentage of the apples are green is 20%.

Is it possible to have a polygon with an exterior angle of 14 degrees
Answer:
No, a polygon cannot have a decimal number of sides.
Explanation:
exterior angle of a polygon = 360 ÷ number of sidesusing the formula:
14 = 360 ÷ number of sides
1/number of sides = 14/360
number of sides = 360/14
number of sides = 25.71428571
Answer:
all polygons have exterior angles that totL to 360 degrees from triangles to 20-gons. so 360 divided by 14 is 25.71 sides which is not possible because what would .71 of a side look like....now this is assuming that you were referring to regular polygon with all sides the same. I suppose you could gave a polygon with a whole number of sides but the relationship between the exterior angles could be such that not all of the angles have the same degree measure. I would say that an exterior angle for any polygon would need to be greater than 0 but less than 360. so my answer is yes it could be possible le
A.(-2, -1) is a solution to the linear system B.(-2, -1)is not a solution to the linear system
Answer:
A. (-2, -1) is the solution to the linear system
Step-by-step explanation:
Substitute for x and y and see if the equations are true.
-1 = 3(-2) +5 . . . . true
-2 +(-1) = -3 . . . . .true
(-2, -1) is the solution to the linear system.
What is the slope of the line?
3(y - 1) = 2x + 2
Rewrite the equation in slope- intercept form.
3(y-1) = 2x + 2
Use the distributive property
3y-3 = 2x + 2
Add 3 to both sides
3y = 2x + 5
Divide both sides by 3
Y = 2/3x + 5/3
Slope = 2/3
The points (2, 5) and (6,-3) fall on a particular line. What is its equation in slope-intercept form?
y = -2
x+ ?
Answer:
y = -2x + 9
Step-by-step explanation:
slope intercept form : y = mx + b
where m = slope and b = y intercept
first let's find the slope
slope formula :
[tex]m = ( \frac{y2 - y1}{x2 - x1} )[/tex]
where the x and y values are derived from the given points
here we are given (2,5) and (6,-3)
(x1,y1) = (2,5) so x1 = 2 and y1 = 5
(x2,y2) = (6,-3) so x2 = 6 and y2 = -3
we now plug these values into the formula
recall formula
[tex]m= ( \frac{y2 - y1}{x2 - x1} )[/tex]
plug in x1 = 2, y1 = 5, x2 = 6 and y2 = -3
m = (-3 - 5) / ( 6 - 2 )
m = (-8)/(4)
m = -2
the slope is -2
now to find the y intercept we plug in the slope and the x and y value of a given point into slope intercept form and solve for b
y = mx + b
given point : (2,5) x = 2 , y = 5, m = -2
5 = -2(2) + b
5 = -4 + b
9 = b
so the equation would be y = -2x + 9
Find the area of the shaded area. Round your answer to the nearest tenth
Answer:
45π
Step-by-step explanation:
To find the area of a circle the formula is πr².
To find the shaded region we will subtract the area of the small circle from the area of the big circle.
Area(big circle)=π9²=81π
Area(small circle)=π6²=36π
81π-36π= 45π

martin works in a furniture store. he earns a base salary of $1,800 per month, plus a 15% commission on the amount of furniture sales he makes during the month. if martin needs to earn at least 3,000 each month to pay his expenses, what is the minimum amount of furniture sales he must make each month?
Answer:
$8000
Step-by-step explanation:
With the provided values you get the equation
1800+.15x=3000
with x being the amount of sales he needs
1. 3000-1800=1200
gives 1200=.15x
2. 1200/.15 = 8000
so x = 8000
