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

What is the first step to solve this equation:
11 - 3x = 44

Question 3 options:

Add 3 to both sides

Add 11 to both sides

Subtract 11 from both sides

Divide 3 on both sides.

Answers

The first step to solving this equation is subtracting 11 from both sides.

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

/3 /3

x = 10

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.

Please help I asked this question earlier and nobody answered! :(

Answers

Answer:

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.
