Answer:
x=3
Step-by-step explanation:
5(2x+1)=35
Step 1: Simplify both sides of the equation.
5(2x+1)=35
(5)(2x)+(5)(1)=35(Distribute)
10x+5=35
Step 2: Subtract 5 from both sides.
10x+5−5=35−5
10x=30
Step 3: Divide both sides by 10.
x=3
I walk each day to school. By what percentage would I need to increase my usual average speed in order for the journey to take 20% less time than usual? C:
Answer:
25%
Step-by-step explanation:
Let v, t be the current average speed and the time taken to reach the school respectively.
As distance = speed x time, so,
distance, d=vt...(i)
Let V be the new average speed in order to to take 20% less time than t.
So, time taken with speed V = t-20% of t = t- 0.2t= 0.8t
As distance is constant, so
d= V(0.8t)= 0.8Vt
hBy using equation (i), we have
0.8Vt = vt
0.8 V = v
V= v/0.8=1.25v
Therefore, the percentage increase in the average speed = [tex]\frac{V-v}{v}\times 100[/tex]
[tex]=\frac{1.25v-v}{v}\times 100[/tex]
=25%
Hence, the percentage increase in the average speed is 25%.

Identify the number of solutions for the equation below:
Answer:
one solutionStep-by-step explanation:
Given the expression
3 -x = 2+x
We re to find the number of solutions we will have:
Subtract 2 from both sides
3-x-3 = 2+x -3
-x = x -1
subtract x from both sides
-x - x = x - 1 - x
-2x =-1
Divide both sides by -2
-2x/-2 = -1/-2
x = 1/2
Since the value of x is just 1, hence the equation has just one solution.

In which choice do all three points lie on the same straight line?
A. (0,0) (1, 1) (2, 4)
B. (5, 1) (-3,0) (-1,2)
C. (2, 10) (4.9) (5,8)
D. (0.1) (2,3) (4,5)
Answer:
D) (0,1) (2,3) (4,5)
Step-by-step explanation:
Explanation
Given Points are A(0,1) , B(2,3) , C(4,5)
slope of the AB
[tex]= \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{3-1}{2-0} =\frac{2}{2} =1[/tex]
Slope of BC
[tex]= \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{5-3}{4-2} =\frac{2}{2} =1[/tex]
Therefore slope of AB and BC are equal
The three points lie on same straight line
The three points are collinear points

Whats values x= 2+/- i are the the roots of the quadratic equation?
Answer:
x^2 - 4x + 5 = 0
Step-by-step explanation:
:)
x = (2 + i) and (2 - i) are the roots of the quadratic equation f(x) = x² - 4x + 5.
What are roots of a quadratic equation?The values of variables satisfying the given quadratic equation are called its roots.
Given (2 + i) and (2 - i) are roots of the quadratic equation.
Let the quadratic equation be f(x).
(x - (2 + i)) and (x - (2 -i)) are the factors of f(x).
Since, f(x) is a quadratic equation, it has only two roots.
f(x) = (x - (2 + i))(x - (2 - i))
f(x) = x² - (2 - i)x - (2 + i)x + (2 - i)(2 + i)
f(x) = x² - 2x + ix - 2x - ix + 4 - i²
f(x) = x² - 4x + 4 + 1
f(x) = x² - 4x + 5

Given the parent function f(x) = 8x + 9, rewrite the function after the following transformation: reflect over the x-axis. Group of answer choices g(x) = -8x + 9 g(x) = -8x - 9 g(x) = 8x - 9 g(x) = 8x + 9
Given:
The parent function is
[tex]f(x)=8x+9[/tex]
To find:
The function after the reflection over the x-axis.
Solution:
We know that, if a function f(x) reflected over x-axis to get the function g(x), then
[tex]g(x)=-f(x)[/tex]
Putting [tex]f(x)=8x+9[/tex], we get
[tex]g(x)=-(8x+9)[/tex]
[tex]g(x)=-8x-9[/tex]
The function after the reflection over the x-axis is [tex]g(x)=-8x-9[/tex].
Therefore, the correct option is B.
