Answer:
x=3/4+1/4√37 or x=3/4+−1/4√37Step-by-step explanation:
Let's solve your equation step-by-step.
−2x−5=2−4x(x−1)
Step 1: Simplify both sides of the equation.
−2x−5=−4x^2+4x+2
Step 2: Subtract -4x^2+4x+2 from both sides.
−2x−5−(−4x^2+4x+2)=−4x^2+4x+2−(−4x^2+4x+2)
4x^2−6x−7=0
For this equation: a=4, b=-6, c=-7
4x^2+−6x+−7=0
Step 3: Use quadratic formula with a=4, b=-6, c=-7.
x=−b±√b2−4ac/2a
x=−(−6)±√(−6)2−4(4)(−7)/2(4)
x=6±√148/8

Step-by-step explanation:
Divide 7 by 15 because that's how you calculate the chance of receiving marbles
7/15 is equal to 0.466667 approx..
To convert to Percent form, multiply by 100
0.466667 *100=46.6667
[tex]\frac{n}{7}[/tex] - 12 = 5n + 5
I need to show my work, please.
Answer:
n= -3.5
Step-by-step explanation:
n/7 - 12 = 5n +5
+12 +12
n/7 = 5n+17
*7 *7
n = (5n+17)*7
n = 35n + 119
-35n -35n
-34n = 119
/-34 /-34
n = -3.5

Answer:
a) x = 14
b) NP = 2 2/9; NL = 2 7/9
Step-by-step explanation:
a) The similarity statement tells you that angle P and angle L have the same measure:
angle L = angle P
3x +18 = 60
x + 6 = 20 . . . . . divide by 3
x = 14 . . . . . . . . . subtract 6
__
b) The proportional segments are ...
PN/NQ = LN/NM
y/3.2 = (5 -y)/4
5y = 4(5 -y) . . . . . multiply by 16
9y = 20 . . . . . . . . add 4y
y = 20/9 = NP
5 -y = (45 -20)/9 = 25/9 = NL

Answer:
-2x+4
Step-by-step explanation:
Evaluate f(x)=4x+5 when x=4.
21
Step-by-step explanation:
=4x+5
=4*4+5
=16+5
=21
The value of function f(x) = 4x + 5 when x = 4 is 21 the answer is 21.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = 4x + 5
Plug x = 4
f(4) = 4(4) + 5
f(4) = 16 + 5
f(4) = 21
Thus, the value of function f(x) = 4x + 5 when x = 4 is 21 the answer is 21.

Answer:
x=9 B
Step-by-step explanation:
3x=27
divide both sides by 3 to get the x alone
28/3=9
Answer:
B: Divide both sides by 3
Step-by-step explanation:
The reason why is because you want to get x by itself and right now it looks like it is married (multiplied) to 3. To get it by itself, you have to get a divorce (be divided). Therefore, you would do 3x/3=x. You would then also have to divide the 27 on the other side. X then should equal 9.

What is the answer to -2.6f + 0.7f - 12 -9
Simplify if needed
DUE TODAY!!!!!!
Answer:
= -1.9f - 21
Step-by-step explanation:
Let's simplify
-2. 6f+ 0.7f- 12 - 9
= - 2.6f+ 0.7 f + - 12 + - 9
Combine like terms
= - 2.6 f+ 0.7 + - 12 + - 9
= (-2.6f + 0.7f ) + ( - 12+-9)
=1.9f+ -21

6. All angles in the figure below are right angles. What is the area of the figure? (1 point)
Answer:
Option (4)
Step-by-step explanation:
Area of the figure given in the picture = Area of large rectangle - Area of rectangle A
Area of rectangle A = Length × Width
= [9 - (2 + 4)] × 3
= 3 × 3
= 9
Area of the large rectangle = Length × Width
= 9 × 5
= 45
Therefore, area of the given figure = 45 - 9
= 36
Option (4) will be the correct option.
