Answer:
x = (3-2√11)/5 ; x= (3+2√11)/5
Step-by-step explanation:
Δ/4 = (b/2)^2 - ac where b is the term that multiplies x, a is the therm that multiplies x^2 and c is the therm without x
Δ/4 = (-3)^2 - (-7*5) = 9 + 35 = 44 = 2^2 *11
x1 = (3 - √2^2 *11)/5 = (3-2√11)/5
x2 = (3+ √2^2 *11)/5 = (3+2√11)/5

I need to print x photos for my scrapbook I called two different stores to ask about the cost of printing photos The first store charges a fee of $3.79 to use the photo machine and then an additional $0.25 per photo. The second store charenly a $0.99 fee to use the photo machine, but the additional cost per photo is $0.35 After comparing the two stores, I realize my overall cost will be the same at each store. What is the value of x, the number of photos I need to print?
Answers
Answer:
x=28
Step-by-step explanation:
3.79+0.25x=0.99+0.35
-0.35x -0.35x
3.79+-0.10x=0.99
-3.79 -3.79

Find the value of x
Answers
Step-by-step explanation:
Given Angle AOC = 90,
Angle AOB + Angle BOC = 90
[tex]3x + 46 + 14 = 90 \\ 3x + 60 = 90 \\ 3x = 90 - 60 \\ 3x = 30 \\ x = 30 \div 3 \\ = 10[/tex]
Answer:
B) 10
Step-by-step explanation:
It is given that the (m<AOC) is (90) degrees. It is also given that (<AOB) and (<BOC) compose (<AOC). Therefore, the following statement can be made;
(m<AOB) + (m<BOC) = (m<AOC)
Substitute,
(3x + 46) + (14) = (90)
Simplify,
3x + 60 = 90
Inverse operations,
3x + 60 = 90
-60 -60
3x = 30

Please help I asked this question earlier and nobody answered! :(
Answers
Answer:
B
Step-by-step explanation:
One way to tell is to put both equations into slope-intercept form. That form is usually written [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.
Solve the first equation for y.
[tex]6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2[/tex]
The slope of this line is -3, and its y-intercept is 5/2.
Solve the second equation for y.
[tex]y+3x=2\\y=-3x+2[/tex]
The slope of this line is -3 and its y-intercept is 2.
The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.

Answer:
m = n = 5√2
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you ...
Sin = Opposite/Hypotenuse
sin(45°) = m/10
m = 10·sin(45°) = 10·(√2)/2 = 5√2
The triangle is isosceles, so m = n.
n = m = 5√2
_____
The side ratios of an isosceles right triangle are 1 : 1 : √2. That is, the legs are 10/√2 = 5√2 in this triangle. It can be useful to remember these ratios for this "special" triangle.
