Answer:
The equation is;
y = 2x^2 -8x + 12
Step-by-step explanation:
The vertex form can be written as;
a(x-h)^2 + k
(h,k) represents the coordinates of the vertex
In this case, we have this as (2,4)
The value of a is positive as the parabola opens up and it is the axis of symmetry
It is the x value that divides the graph into 2
Thus, we have x as = 2
so the equation of the graph will be;
2(x-2)^2 + 4
2(x^2 - 4x + 4) + 4
= 2x^2 -8x + 8 + 4
= 2x^2 -8x + 12

8. Determine the symbolic representation of g(x). Express your answer in
slope intercept form. *
Answers
Answer:
[tex]g(x)=5x+21[/tex]
Step-by-step explanation:
The slope of g(x) is 5 because the slope of h(x) is 5 and g is parallel to h.
In point-slope form:
[tex]g(x)-1=5(x+4)[/tex]
Rearranging for slope intercept form:
[tex]g(x)-1=5x+20\\g(x)=5x+21[/tex]
The measures of the angles of a triangle are shown in the figure below. Solve for x.
(6x+20)
105
(7-10)
Answers
Answer:
x=5
Step-by-step explanation:
Angles in a triangle adds up to 180 degrees
so 105 + (6x+20) + (7x-10) = 180
simplify
115+13x=180
subtract 115 to each side
13x=65
divide by 13
x=5
check work
105 + (6(5) + 20) + (7(5) -10)
105 + (30 +20) +(35 - 10)
105 + 50 + 25 = 180

20% of all the children in a class are left handed.
4 children are left handed.
How many children are there in the class altogether?
Answers
Answer:
There are 20 students in the class
Step-by-step explanation:
Let the total number of children in the class be = x
from the question, we know that 20% of all the children are left-handed. We also know that 20% of the total children in the class = 4.
This means that 20% of x = 4
Wherever we see the word "of" in an arithmetic problem, we should know that it infers a multiplication there.
Hence, we have
[tex]\frac{20}{100} \times x = 4[/tex]
[tex]x = \frac{4 \times 100}{20}= 20[/tex]
There are 20 children in the class altogether
find the value of x.
Answers
Answer:
2
Step-by-step explanation:
Since they are similar triangles then the ratio will be the same on all sides.
You know the one side 5 is the same ratio to 5x so you multiply x to all sides of the little triangle to get the value of the equivalent side in the big one.
so the missing side x times x will equal the big size of the bigger triangle which is 4
x times x = 4 can only be 2

Harold earns $10.50 per hour working at a doctor's office. On Monday he spent 1 5/12 hours filing paperwork, 1 3/4 sending emails and 2 1/3 hours making appointments. What were Harold's earnings? Round your answer to the nearest cent.
Answers
Answer:
the total earnings is $58
Step-by-step explanation:
The computation of earnings is shown below:
= Time spent in filling paperwork + time spent in sending emails + time spent in making appointments
= (1 5 ÷ 12 × $10.50) + (1 3 ÷ 4 × $10.50) + (2 1 ÷ 3 × $10.50)
= 14.875 + 18.375 + 24.50
= $57.75
Hence, the total earnings is $58

If The point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)If the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y)If the point (x, y) rotated about the origin by angle 270° counterclockwise, then its image is (y, -x)∵ The given point is (9, -7)
∴ x = 9 and y = -7
∵ The given point is rotated 270° counterclockwise about the origin
→ By using the third rule above
∴ The image of the point is (y, -x)
→ That mean change the sign of x-coordinate, then switch them

11) 6x2+ 6x3
12) -6x 2 + (-6) x3
13) 5x - 8x
Answers
Answer:
11) 6x^2+ 6x^3 = 6.x.x+6.x.x.x
12) -6x^2 + (-6) x^3 = -6.x.x + (-6).x.x.x
13) 5x - 8x = 5.x -8.x
Step-by-step explanation:
Let us solve the question one by one.
11) 6x^2+ 6x^3
In order to convert the polynomial in the factored form, we see which factors are common in all terms in the polynomial.
[tex]6x^2 = 6.x.x\\6x^3 =6.x.x.x[/tex]
The factored form is:
[tex]= 6.x.x+6.x.x.x[/tex]
12) -6x^2 + (-6) x^3
Similarly, as 11
[tex]-6x 2 =-6.x.x\\-6x^3=-6.x.x.x[/tex]
The factored form is:
[tex]=-6.x.x+ (-6).x.x.x[/tex]
13) 5x - 8x
We can clearly see that there is only one common factor in both terms which is x
[tex]5x = 5.x\\8x = 8.x[/tex]
The factored form is:
[tex]=5.x-8.x[/tex]
Hence,
11) 6x^2+ 6x^3 = 6.x.x+6.x.x.x
12) -6x^2 + (-6) x^3 = -6.x.x + (-6).x.x.x
13) 5x - 8x = 5.x -8.x
The sum of two numbers is 17 and their product is 72. Find the smaller number.
Answers
8+9=17
8x9=72
=========================================
Explanation:
Through guess and check, we find that
8+9 = 17
8*9 = 72
We see that 8 is the answer.
--------------------
Another approach:
Let m and n be the two numbers.
They sum to 17 which leads to m+n = 17. Solving for n gets us n = -m+17.
Their product is 72, so, m*n = 72
Apply substitution and we get the following:
m*n = 72
m*(-m+17) = 72
-m^2 + 17m = 72
-m^2 + 17m - 72 = 0
-1(m^2 - 17m + 72) = 0
m^2 - 17m + 72 = 0
Now apply the quadratic formula
[tex]m = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\m = \frac{-(-17)\pm\sqrt{(-17)^2-4(1)(72)}}{2(1)}\\\\m = \frac{17\pm\sqrt{1}}{2}\\\\m = \frac{17\pm1}{2}\\\\m = \frac{17+1}{2} \ \text{ or } \ m = \frac{17-1}{2}\\\\m = \frac{18}{2} \ \text{ or } \ m = \frac{16}{2}\\\\m = 9 \ \text{ or } \ m = 8\\\\[/tex]
If m = 8, then n = -m+17 = -8+17 = 9.
If m = 9, then n = 8 through similar steps.
We see the two values are 8 and 9, the smaller of which is 8.
