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

Round 1.5 to one decimal place
Answers
Answer:
2
Step-by-step explanation:
Since rounding to the one place relies on the decimal part, the part to focus on is the .5
becuase anything greater or equal to 5 is rounded up, the answer is 2
1.5 rounded to one decimal place will be 2.
What are Places' values?Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.
Given a fraction number 1.5 that needed to be rounded to one decimal place. Since it's at the equidistance from the nearest whole number then we will follow the even number rule.
Rounds towards the nearest neighbor, but if equidistant, it rounds towards the even number. Both 1.5 and 2.5 are rounded to 2
therefore, 1.5 will be 2, when rounded to the nearest tenth.

Kerel wants to buy a Points card for his X-box live account. He can buy a 200-point
card for $10.00 or a 300-point card for $15.00. Which card is the better value?
Answers
Answer:
equal. i think
Step-by-step explanation:
well if 10$ is worth 200 and 15 is worth 300 for me its adding half of the orginal number (200) and get 100 so 200+100=300
Both the cards are having the same value
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first card be = A
Let the second card be = B
Now ,
The value of first card = $ 10.00
The value of second card = $ 20.00
And ,
The total value for 200 point cards = value of first card
The total value for 300 point cards = value of second card
So , the equation will be
200 = 10 A be equation (1)
300 = 15 B be equation (2)
Divide equation (1) by 10 on both sides , we get
A = 20
Divide equation (2) by 15 on both sides , we get
B = 20
Therefore , A = B
Hence , Both the cards are having the same value

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

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.
What is the first step to solve this equation:

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.

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
