Answer:
Step-by-step explanation:
5ˣ⁺² = 5⁹
log₅(5ˣ⁺²) = log₅(5⁹)
x+2 = 9
x = 7
La ecuación de la recta que pasa por los puntos (2,-1) y (1,-5) es:
y= 4x+9
y= 4x-9
y= x-9
ninguna de las anteriores
Given:
A line passes through the points (2,-1) and (1,-5).
To find:
The equation of the line.
Solution:
If a line passes through the two points, then the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the points (2,-1) and (1,-5). So, the equation of the line is
[tex]y-(-1)=\dfrac{-5-(-1)}{1-2}(x-2)[/tex]
[tex]y+1=\dfrac{-5+1}{-1}(x-2)[/tex]
[tex]y+1=\dfrac{-4}{-1}(x-2)[/tex]
[tex]y+1=4(x-2)[/tex]
Using distributive property, we get
[tex]y+1=4(x)+4(-2)[/tex]
[tex]y+1=4x-8[/tex]
Subtract 1 from both sides.
[tex]y+1-1=4x-8-1[/tex]
[tex]y=4x-9[/tex]
Therefore, the correct option is B.

An airplane is flying out an altitude of approximately 2 miles above ground level. The pilot sites a landmark at the angle of depression of 11°. One minute later the pilot sides the same landmark and an angle of depression of 18°. To the nearest 10th of a mile how far did the plane fly in that minute?
Answer:
0.3 miles
Step-by-step explanation:
Using trigonometry : d
Tanθ = opposite / Adjacent
Tan 11 = d1 / 2
2tan11 = d1
0.3887606 miles = d1
Tanθ = opposite / Adjacent
Tan 11 = d2 / 2
2tan18 = d2
0.6498393 miles = d2
d2 - d1 = Distance flown within the minute
0.6498393 - 0.3887606 miles
= 0.2610787 miles
= 0.3 miles
Classify each pair of angles listed below as adjacent or vertical.
Answer:
Adjacent - DBC and ABC, EBA and ABC
Vertical - ABC and DBE, CBD and EBA
Step-by-step explanation:
A vertical pair of angles are opposite to each other and intersect by two lines. They make an x shape.
Adjacent angles are angles that have a common vertex and side but do not overlap. They make a v shape with another line in the middle.

Write the polynomial in descending order: 4x + 3x^2 - 1
Group of answer choice
A. 3x^2 + 4x - 1
B. 1 - 4x + 3x^2
C. -1 + 3x^2 + 4x
D. 4x + 3x^2 - 1
Answer:
3x^2+4x+1
Step-by-step explanation:
Given the polynomial function 4x + 3x^2 - 1
Rearranging in descending order means that we are to arrange the degree power from the highest to the lowest.
The term with the highest degree is 3x^2
Followed by 4x
Then the constant 1
Adding according to the descending powers
The polynomial in descending order will be 3x^2+4x+1

A tree struck by lightning broke at a point 12 feet above the ground. What was the height of the tree to the nearest tenth of a foot., 12 squared + 39 squared = ??
Answer:
52.8 feets
Step-by-step explanation:
From the diagram :
The height of tree woulb be :
Height above the ground (at breakpoint) + hypotenus
Hypotenus, h cab be obtained using Pythagoras rule :
h² = opp² + adj²
h² = 39² + 12²
h² = 1665
h = sqrt(1665)
h = 40.804 feets
Height of tree to the nearest tenth ;
40.804 feets + 12 feets
= 52.804 feets
= 52.8 feets

Step-by-step explanation:
Which angle is complementary to DFE? Pls answer
Answer:
<DFA
Step-by-step explanation:
When combined (<DFA and <DFE), they'll form 90 degrees which will make them complementary
Answer:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle. When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
The complement of −135° is the angle that when added to −135° forms a right angle (90° ).

Could you guys please solve these equations?
12x-17 = 6x+7 solve for x
-8b+1 = -5(b + 4) solve for b
350+10(n-7) = 630+2(n-15) solve for n
thank you
Answer:
x = 4
b = 7
n = 40
I hope this helps!!!
Step-by-step explanation:
1) 12x-17 = 6x+7
+17 +17
*do this because you want to get all of the variables to one side and all of the constants to one side*
12x = 6x + 24
-6x -6x
6x = 24
*divide by 6 to get x alone, so you 24/6 = 4*
x = 4
2) -8b+1 = -5(b+4)
*must multiply -5 by everything in the parenthesises*
-8b+1 = -5b-20
-1 -1
-8b= -5b-21
+5b +5b
-3b = -21
b = 7
3) 350+10(n-7) = 630+2(n-15)
350+10n-70 = 630+2n-30
*combine like terms on both sides of the equation*
280+10n = 600+2n
-280 -280
10n = 320+2n
-2n -2n
8n = 320
n = 40
