Step-by-step explanation:
Answer:
1/12
Step-by-step explanation:
Solve the equation
2x^2 + 8x - 1 = 0
by completing the square.
Give your answers correct to 2 decimal places.
Step-by-step explanation:
2x² + 8x - 1 = 0
2(x + 2)² - 9 = 0
2(x + 2)² = 9
(x + 2)² = 4.5
x = √4.5 - 2 or x = -√4.5 - 2
x = 0.12 or x = -4.12.

Which equation shows one way to find the value of 45 × 4? 45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ? 45 × 4 = (9 × 5) × (2 × 2) = (9 + 5) × (2 + 2) = 14 × 4 = ? 45 × 4 = (9 × 5) × (2 × 2) = (9 + 2) × (5 + 2) = 11 × 7 = ? 45 × 4 = (9 × 5) × (2 × 2) = (18 × 2) × (10 × 9) = 36 × 90 = ?
Answer:
45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ?
Step-by-step explanation:
Which equation shows one way to find the value of 45 × 4?
45 × 4
Splitting each number into factors of each other
45 = 9 × 5
4 = 2 × 2
45 × 4 = (9 × 5) × (2 × 2)
45 × 4 = (9 × 2) × (5 × 2)
45 × 4 = 18 × 10

Use the figures to complete the statements proving the converse of the Pythagorean theorem.
Drag and drop a phrase, value, or equation into the box to correctly complete the proof.
To prove the converse of the Pythagorean theorem, we must show that if △ABC has sides of a, b, and c such that a² + b² = c² , then △ABC is a right triangle.
Define △DEF so that it is a right triangle with sides a, b, and hypotenuse x. By the Pythagorean theorem, a² + b² = x² .
Since a² + b² = c² and a² + b² = x², it must be true that c² = x². Since sides of triangles are positive, then we can conclude that Response area. Thus, the two triangles have congruent sides and are congruent.
Finally, if △ABC is congruent to a right triangle, then it must also be a right triangle.
Two right triangles with points labeled in capital letters and sides labeled in lower case letters.

Answer:
the answer is 10
Step-by-step explanation:
the formula for distance is square root ( of the entire equation),, (x1-x2) squared +(y1-y2) squared so (-5-3)+(4-(-2)) ( both answers squared) equals -8 squared plus 6 squared and you get 64+36 which is 100 and the square root of 100 is 10. Hope that wasn't confusing

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
Answer:
The opposite of -10·t and t - 10·t is t
Step-by-step explanation:
1) The opposite of 4·x and -5 + 4·x is given as follows;
-4·x + (-5 + 4·x) = -4·x -5 + 4·x = -4·x + 4·x - 5 = 0 - 5 = -5
2) The opposite of -10·t and t - 10·t is given as follows;
-(-10·t) + (t - 10·t) = 10·t + t - 10·t = 10·t - 10·t + t = 0 + t = t
3) The opposite of (-7 - 4·v) and -4·v is given as follows;
-(-7 - 4·v) + (-4·v) = -1 × (-7 - 4·v) - 4·v = 7 + 4·v - 4·v = 7 + 0 = 7

Determine whether the function f(x) = -9.5 + 6 + x² is even, odd or neither.
Answer:
The function f(x) = -9.5 + 6 + x² is neither odd or even.
Step-by-step explanation:
We know that a function is termed as 'even' when
f(-x) = f(x) for all x
We know that a function is termed as 'odd' when
f(-x) = -f(x) for all x
Given the function
f(x) = -9.5x⁵ + 6 + x²
substitute x with -x
f(-x) = -9.5(-x)⁵ + 6 + (-x)²
as (-x)⁵ = -x⁵, so
f(-x) = -(-9.5x)⁵ + 6 + (-x)²
Apply exponent rule: (-a)ⁿ = aⁿ, if n is even
f(-x) = -(-9.5x)⁵ + 6 + x²
Apply rule: -(-a) = a
f(-x) = 9x⁵ + 6 + x²
As
f(-x) ≠ f(x) ≠ -f(x)
Therefore, the function f(x) = -9.5 + 6 + x² is neither odd or even.

Jade has 100 to spend on shoes and socks. She buys a pair of shoes for 75 and wants to wants to spend the rest of the money on socks. Each of socks cost $3.50. let n represent the number of the pair of socks that jade can buy. Which inequality represents her situation?
Answer:
75 + 3.5n ≤ 100
Step-by-step explanation:
Given that:
Total amount = $100
Cost of shoe = $75
Cost per socks = $3.50
n = number of socks pairs
Cost of shoe + (cost per pair of socks * number of socks) ≤ total amount
75 + (3.50 * n) ≤ 100
75 + 3.5n ≤ 100
1.5:4=9:(2y+5)
Solve for y
Answer:
y = 9.5
Step-by-step explanation:
Express the ratios in fractional form, that is
[tex]\frac{1.5}{4}[/tex] = [tex]\frac{9}{2y+5}[/tex] ( cross- multiply )
1.5(2y + 5) = 36 ( divide both sides by 1.5 )
2y + 5 = 24 ( subtract 5 from both sides )
2y = 19 ( divide both sides by 2 )
y = [tex]\frac{19}{2}[/tex] = 9.5

what is the image point of (8,-7) after a translation right 1 unit and up 4 units?
Answer:
It is (9,-3) because x increased by 1 unit and y increased by 4 units.
Answer:
[tex](9,-3)[/tex]
Step-by-step explanation:
[tex](8,-7)[/tex]
If it moves right, add the value to the x-coordinate. If it moves left, subtract the value from the x-coordinate. In this case, because the point was translated 1 unit right, we add 1 to the x-coordinate 8.
[tex](9,-7)[/tex]
If it moves up, add the value to the y-coordinate. If it moves down, subtract the value from the y-coordinate. In this case, because the point was translated 4 units up, we add 4 to the y-coordinate.
[tex](9,-3)[/tex]

"The difference between four-fifths of
a number and 11 is -46."
Answer:
The number is -43.75.
Step-by-step explanation:
4x/5 - 11 = -46
4x/5 = -35
x = -43.75
Answer:
-43.75
Step-by-step explanation:
This is the answer because:
1) We know that 4/5 of a number has to equal -35 since -46 + 11 = -35.
2) 4/5x = -35 (solve for x): -35 ÷ 4/5 = -43.75
3) 4/5 x -43.75 = -35, I got this by solving for x (look at step 2)
Therefore, the answer is -43.75

slope and y intercept of 5x + 8y = 8
Answer:
Slope: -5/8
y intercept: (0,1)
Step-by-step explanation:
The slope of the line will be {m} = -5/8 and the y - intercept will be 1.
What is direct variation?Direct variation of a quantity {y} with respect quantity {x} means that the value of {y} increases as the the value of {x} increases. Mathematically -
y = Kx
K = y/x
where -
{K} is scale factor. It also tells by how many times is {y} greater than {x}.
Given is the equation of a straight line as -
5x + 8y = 8
We can rewrite the equation as -
5x + 8y = 8
8y = - 5x + 8
y = -(5/8)x + 1
So the slope will be -
m = -(5/8)
c = 1
Therefore, the slope of the line will be {m} = -5/8 and the y - intercept will be 1.

(3x-2y=-16)first put in standard form y=mx+b
(-2y=-3x-16) divide both sides by -2
y=3/2x+8
Answer:
C
Step-by-step explanation:
By opposite I'm going to assume they mean the perpindicular line
To do this you first need to convert the function into linear form
So we have 3x-2y=-16
and so we can add 2y and 16 to both sides to get
3x+16=2y
then divide by 2 to get
3/2x+8=y
This is our function in linear form but now we need the opposite by taking the negative reciprocal of the slope
This means our near equation is now -2/3x+8 while none of them give that as an option directly if you simplify C it will match

A rectangular soccer field may have a width between 50 and 100 yards and a length
between 100 and 130 yards. One particular soccer field has a perimeter of 320 yards. Its
length measures 40 yards more than its width. What are the dimensions of this field?
The length is___yards.
The width is____yards.
Answer:
[tex]perimeter = 2(l + w) \\ but \: length = 40 \times width \\ perimeter = 2(40w + w) \\ p = 2(41w) \\ 320 = 2(41w) \\ w = \frac{320}{(2 \times 41)} \\ w = 3.902 \: yards \\ length = 40 \times w \\ = 40 \times 3.902 \\ l = 156.08 \: yards[/tex]
9514 1404 393
Answer:
length: 100 yardswidth: 60 yardsStep-by-step explanation:
Let w represent the width of the field. Then the length is (w+40), and the perimeter is ...
P = 2(L +W)
320 = 2((w+40) +w) . . . . fill in values
160 = 2W +40 . . . . . . . . . divide by 2, collect terms
80 = w +20 . . . . . . . . . . . divide by 2
60 = w . . . . . . . . subtract 20
w+40 = 100
The length is 100 yards; the width is 60 yards.
