[tex]x^{2}-8x+16=25[/tex]
Answer:
x = 9 ; -1
Step-by-step explanation:
[tex]x {}^{2} - 8x + 16 = 25 \\ x {}^{2} - 8x + 16 - 25 = 0 \\ {x}^{2} - 8x - 9 = 0 \\ (x + 1)(x - 9) = 0 \\ x = - 1 \\ x = 9[/tex]

Find the other endpoint of the line segment with the given endpoint and midpoint.
Endpoint: (-9,7), midpoint: (10, -3)
Answer:
endpoint is (29, -13)
Step-by-step explanation:
Formula for midpoint is [tex](\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )[/tex]
So, let [tex](x_{2} , y_{2} )[/tex] be the coordinates of the endpoint you are looking for.
[tex]x_{1} = -9[/tex] and [tex]y_{1} = 7[/tex]
[tex](\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} )[/tex] = (10, -3)
[tex]\frac{-9 + x_{2} }{2} = 10[/tex] [tex]\frac{7 + y_{2} }{2} = -3[/tex]
-9 + [tex]x_{2}[/tex] = 20 7 + [tex]y_{2} = -6[/tex]
[tex]x_{2} = 29[/tex] [tex]y_{2} = -13[/tex]
endpoint is (29, -13)

Answer:
f(0)=9
Step-by-step explanation:
All you do is plug in x=0 into the function.
In this case:
f(x)=10^x+8
f(0)=10^0+8
f(0)=1+8
f(0)=9
Therefore, f(0)=9
Answer:
9
Step-by-step explanation:
You put 0 for x
10^0=1, so 1 +8 is 9

what is the equation for (0,3) and (1,1)
Find the product of (x + 5)^2
Answer:
x^2 + 10x + 25.
Step-by-step explanation:
When you have questions like these, where there is an (x + something)^2,
you just need to put it into this form:
x^2 + ____x + ____.
For the first blank, add 5 + 5 in this case.
For the second blank, multiply 5 * 5.
5 + 5 = 10.
5 * 5 = 25.
So the final answer is:
x^2 + 10x + 25.

Given constants a and b such that x2 + ax + b has factors (x + 7) and (x + 2) what is a?
Answer:
a=9 , b=14
Step-by-step explanation:
Just do the operation (x+7)(x+2)
x(x)+x(2)+7(x)+7(2)
x^2+2x+7x+14
x^2+9x+14
So a=9 and b=14

find the coordinates of the midpoint of AB given A (2,3) and B (4, -2)
Answer:
(3, 1/2)
Step-by-step explanation:
The x-coordinate of the midpoint of AB is the arithmetic mean of 2 and 4, which comes out to 3. The y-coordinate of the midpoint of AB is the arithmetic mean of 3 and -2, which comes out to 1/2.
Thus the midpoint of AB is (3, 1/2).
Can the sides of a triangle have lengths 8.6, 6.6, and 3.3?
yes
no
Answer:
Yes
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of the lengths of any 2 sides of a triangle must exceed the length of the third side.
8.6+6.6>3.3 is true
6.6+3.3>8.6 is true
3.3+8.6>6.6 is true

Which of the coordinate pairs is a point on the line y = -2/5x + 4?
A.) (2, 3)
B.) (-5, 6)
C.) (6, 2)
D.) (-2/5, 4)
Answer:
B.) (-5, 6)
Step-by-step explanation:
to solve algebraically, test the coordinate pairs in the equation [tex]y = -\frac{2}{5}x + 4[/tex]
to solve graphically, enter the equation [tex]y = -\frac{2}{5}x + 4[/tex] into a graphing calculator and graph the coordinate pairs as well to see which one is on the line.
(2, 3) is NOT a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
2 is the x-value and 3 is the y-value. coordinate pairs are always written as (x, y).plug in 2 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(2) + 4now plug in 3 for y.
y = -2/5(2) + 4 ⇒ 3 = -2/5(2) + 4your equation is now 3 = -2/5(2) + 4. begin simplifying by multiplying -2/5 and 2.
3 = -2/5(2) + 4 ⇒ 3 = -0.8 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add -0.8 + 4 to simplify the rest of the right side of the equation.
3 = -0.8 + 4 ⇒ 3 = 3.23 and 3.2 are not equal, therefore (2, 3) is not a solution.
(-5, 6) IS a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
-5 is the x-value and 6 is the y-value. coordinate pairs are always written as (x, y).plug in -5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(-5) + 4now plug in 6 for y.
y = -2/5(-5) + 4 ⇒ 6 = -2/5(-5) + 4your equation is now 6 = -2/5(-5) + 4. begin simplifying by multiplying -2/5 and -5.
6 = -2/5(-5) + 4 ⇒ 6 = 2 + 4now add 2 + 4 to simplify the rest of the right side of the equation.
6 = 2 + 4 ⇒ 6 = 66 and 6 are equal, therefore (-5, 6) is a solution.
although we have identified (-5, 6) as a solution, i'm still going to check the rest of the points just to be sure! :)
(6, 2) is NOT a solution.
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
6 is the x-value and 2 is the y-value. coordinate pairs are always written as (x, y).plug in 6 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(6) + 4now plug in 2 for y.
y = -2/5(2) + 4 ⇒ 2 = -2/5(2) + 4your equation is now 2 = -2/5(6) + 4. begin simplifying by multiplying -2/5 and 6.
2 = -2/5(6) + 4 ⇒ 2 = -2.4 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add -2.4 + 4 to simplify the rest of the right side of the equation.
2 = -2.4 + 4 ⇒ 2 = 1.62 and 1.6 are not equal, therefore (6, 2) is not a solution.
(-2/5, 4) is NOT a solution.
i see that they want to trick you with this one by using the values that are in other spots in the equation... that's crafty
steps for solving algebraically:
first, identify the x and y values in your coordinate pair.
-2/5 is the x-value and 4 is the y-value. coordinate pairs are always written as (x, y).plug in -2/5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)
y = -2/5x + 4 ⇒ y = -2/5(-2/5) + 4now plug in 4 for y.
y = -2/5(-2/5) + 4 ⇒ 4 = -2/5(-2/5) + 4your equation is now 4 = -2/5(-2/5) + 4. begin simplifying by multiplying -2/5 and -2/5.
4 = -2/5(-2/5) + 4 ⇒ 4 = 0.16 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)now add 0.16 + 4 to simplify the rest of the right side of the equation.
4 = 0.16 + 4 ⇒ 4 = 4.164 and 4.16 are not equal, therefore (-2/5, 4) is not a solution.
as for finding the solution on a graph, enter the equation for the line as well as the coordinate pairs into a graphing calculator. here i used a handy little site called desmos in order to graph all of this. the first photo i attached contains what i entered into the calculator, and the second photo i attached shows the graph. as you can see, the only point that is actually on the line is (-5, 6), which is why (-5, 6) is a solution to [tex]y = -\frac{2}{5}x + 4[/tex] , and the other coordinate pairs are not solutions to that equation because they are not on the line.
i hope this helps! have a lovely rest of your day <3

Which expression is equivalent to
5(6p + 5) + 2(8p + 3)?
Answer:
46p + 31
hope it's helpful
Answer:
46p + 31
Step-by-step explanation:
Distribute : 5(6p + 5 ) to get 30p+25
Distribute : 2(8p + 3) to get 16p + 6
new expression : 30p + 25 + 16p + 6
Add these together to get : 46p + 31
i hope this helps (:

The correct answer is
2 cents.
Answer:
the answer is 0.0800320128 or in simplified form 0.08
Step-by-step explanation:
First you divide 12 ÷ 5.88 = 2.04081632653. Then you divide 20 ÷ 10.20 = 1.96078431373. Lastly you subtract 2.04081632653 - 1.96078431373 = 0.0800320128 or 0.08
As a part of their weather unit, Anoki’s science class took a hot air balloon ride. As they passed over a fenced field, the angle of depression of the closer side of the fence was 32°, and the angle of depression of the farther side of the fence was 27°. If the height of the balloon was 800 feet, estimate the width of the field. Round your answer to the nearest foot.
Hello there!
I hope you and your family are staying safe and healthy!
P.S. I did my best drawing the problem :)
[tex]Tan 32 = \frac{800}{x}[/tex]
[tex]x = \frac{800}{tan32}[/tex]
[tex]Tan 27 = \frac{800}{y}[/tex]
[tex]y=\frac{800}{tan27}[/tex]
