Answer:
Step-by-step explanation:
4. A = P + Prt
a. Solve for r
Prt = P - A
r = (P - A)/Pt
b. Solve for t
Prt = P - A
t = (P - A)/Pr
5. Ax + By = C
a. By = C - Ax
y = (C - Ax)/B
b. Ax = C - By
x = (C - By)/A
6. y = mx + b
a. mx + b = y
mx = y - b
x = (y - b)/m
b. mx + b = y
mx = y - b
m= (y - b)/x
c. mx + b = y
b = y - mx
Answer:
yea you have to line it up
Step-by-step explanation:Step-by-step explanation:
For Sienna to be able to take the square root of both sides while solving a quadratic equation, she must have an expression with square on at least, the side that contains the variable she is trying to determine. Equation of the form:
(x + a) ² = b
'a' and 'b' could be any number, -1, 0, 1/3, -5/6, anything really.
So, she can take square roots of both sides then, like this
√(x + a)² = √b
x + a = ±√b
x = -a ± √b
Square roots always cancel out squares, and the '±' is because a square is satisfies by both + and -, 3² = 9, and (-3)² = 9.
It is the nature of the problem being solved that determines if we take just one or both of these answers.
In triangle ABC angle c = 180-78-40 = 62 degrees
For the triangles to be congruent angle z must equal angle C
Solve for x:
2x + 8 = 62
Subtract 8 from both sides:
2x = 54
Divide both sides by 2:
X = 27
Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.
A. False
B. True
C. True
Answer:
G. Point B
Step-by-step explanation:
The two numbers closest to √140 are 11 and 12.
The squares would be 121, and 144.
140 is closer to 144, so the answer will be Point B.
