Rewrite the equation in the form (x−p)2=q. 0=x2-16x+26
Answer:
(x - 8)² = 38
Step-by-step explanation:
Given
x² - 16x + 26 = 0 ( subtract 26 from both sides )
x² - 16x = - 26
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 8)x + 64 = - 26 + 64
(x - 8)² = 38 ← as required

Determine whether side-angle-angle (SAA) is a valid means for establishing triangle congruence. In this case, you know the measure of a side, an adjacent angle, and the angle opposite to the side. If it is a valid criterion, explain why. If it is not valid, use GeoGebra to create a counterexample demonstrating that it doesn't work and give an explanation. If you construct a counterexample, take a screenshot of your work, save it, and insert the image in the space below.

A scientist needs 10 liters of a 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs? Write and slove an equation to match the situation. :
Equation:________________________
Solution:____ liters of 5% and _____ liters of 40%
Answer:
Equation: X × 0.4 + (10 - X)×0.05 = 10 × 0.2
Solution: 5.71 liters of 5% and 4.29 liters 40%
Step-by-step explanation:
The volume of the 20% acid solution the scientist needs = 10 liters
The concentration of the solution she has = 5% and 40%
Therefore, we have;
X volume of the 40% solution is mixed with 10 - X volume of the 5% solution, to obtain 10 liters of the 20% solution
Therefore, we have;
Equation: X × 0.4 + (10 - X)×0.05 = 10 × 0.2
0.4·X + 0.5 - 0.05·X = 2
0.35·X = 2 - 0.5 = 1.5
X = 1.5/0.35 = 30/7
∴ The volume of the 40% solution = 30/7 liters ≈ 4.29 liters
The volume of the 5% solution = 10 - X = 10 - 30/7 = 40/7 liters ≈ 5.71 liters
Therefore, we have;
5.71 liters of 5% solution and 4.29 liters 40% solution.

Which statements are true about the graph of the function f(x) = x2 - 8x + 5? Select three options.
The function in vertex form is f(x) = (x - 4)2 - 11.
The vertex of the function is (-8,5).
The axis of symmetry is x = 5.
The y-intercept of the function is (0.5).
The function crosses the x-axis twice
Answer:
A, D, E
Step-by-step explanation:
The statements that are true about the graph of the function are
The function in vertex form is f(x) = (x - 4)^2 - 11.The y-intercept of the function is (0,5).The function crosses the x-axis twiceVertex and intercept of a functionThe standard equation of a function in vertex form is expreseed as:
a(x-h)^2 + k
Given the quadaratic function f(x) = x^2 - 8x + 5, the expression in vertex form is given as:
f(x) = (x^2-8x + 4^2) - 16 + 5
f(x) = (x-4)^2 - 16 + 5
f(x) = (x-4)^2 - 11
Find the y-intercept.
This is the point here x = 0
f(0) = 0^2 - 8(0) + 5
f(0) = 5
Hence the y-intercept of the function is at (0, 5)
Since the quadratic function has a leading degree of 2, hence the function crosses the x-axis twice

Help Asap !Solve For X In The Diagram.
Answer:
X = 5
Step-by-step explanation:
suppose that angle TSU is y so
23x+5+y = 180
23x+y = 175
now again in traingle TSU
55+14x-5+y = 180
x = 130-y /14
substitute the value of x in 1st equation
ans will be 5
Answer:
x = 6.111
Step-by-step explanation:
The supplement of <AST = 180 - (23x - 5) That supplement is inside the triangle.
Solution
Add the three angles together to get 180
180-(23x - 5) + 14x-5 + 55 = 180 Remove the brackets
180 - 23x + 5 + 14x - 5 + 55 = 180 Combine
-9x + 55 + 180 = 180 Subtract 180 from both sides.
-9x + 55 = 0 Subtract 55 from both sides
-9x = - 55 Divide by -9
x = -55/-9
x = 6.111
Check
180 - (23*6.111 - 5) + 14*6.111 - 5 + 55= 180
180 - 140.555 + 5 + 85.555 -5 + 55 = 180
39.445 + 85.555 + 55 = 180
180 = 180
