-2x + 9 = 21
Step 1: subtract 9 from both sides.
-2x = 12
Step 2: divide both sides by -2.
X = -6

Given:
The graph of a quadratic function [tex]y=x^2-4x+3[/tex].
To find:
(a) The coordinates of the turning point.
(b) The roots of the equation [tex]y=x^2-4x+3[/tex]
Solution:
(a)
From the given graph it is clear that first the graph is decreasing after that it is increasing. So, the minimum point is the turning point.
The turning is at (2,-1) because the distance between the turning point from the y-axis is 2 and from the x-axis is 1 in the downward direction.
Therefore, the coordinates of the turning point are (2,-1).
(b)
The x-intercepts are the roots of an equation because roots are the x-coordinates of the points where the graph intersect the x-axis.
From the given graph it is clear the graph intersect the x-axis at x=1 and x=3.
Therefore, the roots of the given equation are 1 and 3.

Mike took a taxi from his home to the airport. The taxi driver charged an initial fee of 6plus3 per mile. The total fare was $24, not including the tip. How many miles did Mike travel by taxi on this ride?
A 2
B 6
C 8
D 10
Answer:
6 miles.
Step-by-step explanation:
To solve this problem, lets make an equation in slope-intercept form (y = mx + b)
The initial fee is $6. This is our y-intercept (b) as it is unchanging.
Our slope (m) would be $3, as it changes value per mile, which will be represented by x.
$24 was the total fare, so this is our y.
We have:
24 = 3x + 6
Subtract 6 from both sides.
24 - 6 = 3x + 6 - 6
We get:
18 = 3x
Divide by 3 on both sides.
18/3 = 3x/3
We get:
6 = x
So, Mike traveled 6 miles.

what is the solution set of this inequality x < -10 i need help
Answer:
x= 1 (any number greater than -10)
Step-by-step explanation:
">" this sign shows that any number greater than -10 can be x. There is no specific answer.
Answer:
The solution set of an inequality is < (less than) or > (greater than) to compare two or more numbers. Example 12 > - 10.
Step-by-step explanation:
When comparing two numbers, like 5 and 8, you probably recognize that the number 5 is less than the number 8. You probably also realize that the number 8 is greater than the number 5. In math, we use the inequality symbols < and > to compare two or more numbers.

15 - 3x = 11 - 3x + 4
Answer:
Infinitely Many Solutions!
Steps I used to get the answer :
1. Cancel -3x−3x on both sides.
15=11+4
2. Simplify 11+4 to 15.
15=15
3. Since both sides equal, there are infinitely many solutions.
Infinitely Many Solutions!
Done by NeighborhoodDealer.
Answer:
Step-by-step explanation:
Solve for x:
15 - 3x = 11 - 3x + 4
Subtract 4 from both sides
15 - 3x - 4 = 11 - 3x + 4 - 4
11 - 3x = 11 - 3x
This equation has infinite solutions since both sides of the equation are equal.

Someone please help me quick! Pleaseee
Answer:
B
Step-by-step explanation:
Reflect x-axis means (x,y) becomes (x, -y)
Shrink by 1/3 means f(x) = x becomes f(x) = 1/3x
Up 4 units means f(x) = x becomes f(x)= x + 4
So lets put that together
[tex]f(x) = \sqrt{x}[/tex]
[tex]f(x) = -\sqrt{x}[/tex]
[tex]f(x) = -\frac{1}{3} \sqrt{x}[/tex]
[tex]f(x) = -\frac{1}{3} \sqrt{x} + 4[/tex]

Brian has saved five dollars in dimes quarters and half dollars she finds that she has 30 coins all together and there are four times as many quarters as there are half dollars how many dimes does Brian have
9514 1404 393
Answer:
20 dimes8 quarters2 half-dollarsStep-by-step explanation:
Let d, q, h represent the numbers of dimes, quarters, and halves Brian has. We can write 3 equations in these 3 variables:
10d +25q +50h = 500 . . . . value of the coins, in cents
d + q + h = 30 . . . . . . . . . . . total number of coins
4h = q . . . . . . . . . . . . . . . . . four times as many quarters as halves
Using the last equation to substitute into the other two, we get ...
10d + 150h = 500
d +5h = 30
The second equation can be written as ...
5h = 30 -d
and the first can be written to facilitate substitution:
10d +30(5h) = 500
10d +30(30-d) = 500 . . . . . substitute for 5h
900 -20d = 500 . . . . . . . . . simplify
400 = 20d . . . . . . . . . . . . . add 20d-500 to both sides
d = 20 . . . . . . . . . . . . . . . . divide by 20
Brian has 20 dimes.
Given the functions f(x) = x ^ 3, g(x) = 9 and h(x) = 2x , what is an expression equivalant to f(2x) + 3g(x)/h(x) + 3?
Answer:
an expression equivalent to f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3
Step-by-step explanation:
As given ,
f(x) = x³ , g(x) = 9 , h(x) = 2x
Now,
f(2x) = (2x)³ = 2³.x³ = 8x³
⇒f(2x) = 8x³
Now,
[tex]\frac{g(x)}{h(x)} = \frac{9}{2x} = \frac{9}{2}x[/tex]
⇒[tex]3\frac{g(x)}{h(x)} = 3.\frac{9}{2}x = \frac{27}{2}x[/tex]
∴ we get
f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

At a dance, 25% dresses up in a superhero costume, 32% as a scary character, 10% as an entertainer, 15% as a children's movie character, and 16% did not dress up at all. If a total of 250 students attended the dance and 15% of the scary character students were girls, how many boys dressed up as a scary character?
Answer:
68 boys
Step-by-step explanation:
32% of 250 = 80
of 80 scary characters, 15% were girls
80 x .15 = 12 (girls)
80 - 12 = 68 (boys)

Answer:
y = x/2 +4
Step-by-step explanation:
new slope = -1/-2 = 1/2
x1 = -4, y1= 2
y-y1 = m(x-x1)
y - 2 = 1/2 {x- (-4)}
y-2 = 1/2 (x+4)
y-2 = x/2 + 2
y = x/2 +2+2
y = x/2 +4
