Answer:
the fist one is A and the second one is D
Step-by-step explanation:
If one of the roots of the equation x²- 4x + k=0exceeds the other by 2, then find the roots and determine the value of k
Answer:
roots: 1 and 3
k = 3
Step-by-step explanation:
2 roots: p and p+2
(x-p) (x-p-2) = x² - 4x + k
x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k
-2 (p+1) = -4
p+1 = 2
p = 1 ... root 1
p' = 1+2 = 3 ... root 2
k = p² + 2p = 3
check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k

2x+3=x-4 what is the question
Answer:
x = - 7
Step-by-step explanation:
Step 1:
2x + 3 = x - 4 Equation
Step 2:
x + 3 = - 4 Subtract x on both sides
Answer:
x = - 7 Subtract 3 on both sides
Hope This Helps :)
Answer:
x = -7
Step-by-step explanation:
Given Equation :-
2x + 3 = x - 4Solution :-
Step 1 :- Subtract x from both sides
2x - x + 3 = x - x - 4x + 3 = - 4Step 2 :- Move constant to the right hand side and change their sign.
x = - 4 - 3Step 3 :- Combine like terms
x = -7Write the equation of the circle with a center at (11,6) and a radius of 6.
Answer:
(x-11)^2 + (y-6)^2= 6^2
Step-by-step explanation:
Answer:
(x - 11)² + (y - 6)² = 36
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (11, 6 ) and r = 6, then
(x - 11)² + (y - 6)² = 6² , that is
(x - 11)² + (y - 6)² = 36

58.12 x 2 = 116.24 feet
Create an equation to solve for x using the trapezoid midsegment formula:
Answer:
Equation for x: 3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]
x = 9
CD = 17
GH = 21
Step-by-step explanation:
The midsegment formula for a trapezoid is
GH = [tex]\frac{CD + FE}{2}[/tex]
3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]
6x - 12 = 2x + 24
4x = 36
x = 9
CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17
GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21

What is the surface area of this cylinder?
Answer:
1067.6 m²Step-by-step explanation:
Given that
r = 10 mh = 7 mπ ≈ 3.14Find the surface area of the cylinder!
Equation =
2πr × (r+h) =(2 × 3.14 × 10) × (10 + 7) =
62.8 × 17 ≈
1067.6 m²The surface area of the cylinder ≈ 1067.6 square metres
_________________
#Indonesian - kexcvi
Answer:
Use this formula to calculate for the surface area of cylinder.
Step-by-step explanation:
A=2π r h+2 π r^2.
use r = 10 m and h = 7 m
2 (3.14) (10) 7 + 2 (3.14) 10 ^2. = 439.6 + 628 = 1067.6
round to the nearest hundredths = 1068
Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. x=2y-7 and 4x+y=71 *
Answer:
The solution is (15, 11) There is only one solution.
Step-by-step explanation:
Solve this system using substritution. In the second equation replace x with 2y - 7, obtaining:
4(2y - 7) + y = 71, which simplifies as follows:
8y - 28 + y = 71, or
9y = 99. then y must be 11. If y is 11, then x = 2y - 7, or x = 2(11) - 7 = 15
The solution is (15, 11) There is only one solution.

Reparte 280 euros entre 3 personas, de forma que la 1º reciba el triple que la 2º y esta el doble de la3º
Answer:
x = 31.11
Step-by-step explanation:
Let us assume the third person receives be x
Now the second person receives be 2x
And, the second be 3(2x) = 6x
The total is 280
Now the equation is
x + 2x + 6x = 280
9x = 280
x = 31.11
Function f is defined by the equation f (x) = 10x + 2. What is the value of f (2)?
Answer:
f(2) = 22
Step-by-step explanation:
To find f(#), plug the number into each x of the equation.
f(x) = 10x + 2
f(2) = 10(2) + 2
Simplify the parentheses by multiplying.
f(2) = 20 + 2
Add.
f(2) = 22
