10+2=12 then you do 12 divided by 3 because he got 3 times as many wich means he had 4 books originally!! :D
Which quadratic function is represented by the table? f(x) = 3x2 2x – 5 f(x) = 3x2 – 2x 5 f(x) = 2x2 3x – 5 f(x) = 2x2 – 2x 5
For the values of x, the quadratic function f(x) = 3x² – 2x + 5 is satisfied. Then the correct option is B.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
At x = –2, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(–2)² – 2(–2) + 5
f(x) = 12 + 4 + 5
f(x) = 21
At x = –1, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(–1)² – 2(–1) + 5
f(x) = 3 + 2 + 5
f(x) = 10
At x = 0, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(0)² – 2(0) + 5
f(x) = 0 + 0 + 5
f(x) = 5
At x = 1, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(1)² – 2(1) + 5
f(x) = 3 – 2 + 5
f(x) = 6
At x = 2, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(2)² – 2(2) + 5
f(x) = 12 – 4 + 5
f(x) = 13

A right triangle has legs of length 136 cm and 119 cm. What is the length of the hypotenuse of the right triangle? Enter the answer, rounded to the nearest tenth, in the box.
Answer:
Hypotenuse= 180.7 cm
Step-by-step explanation:
Using Pythagoras' theorem:
a^2+b^2=c^2 (let c= Hypotenuse "H")
(136)^2 + (119)^2 = H^2
18496+14161 =H^2
H^2= 32657
Taking square root on both sides
[tex]\sqrt{H}[/tex]= [tex]\sqrt{32657}[/tex]
H=180.7
Find the length of the third side. If necessary, round to the nearest tenth 22 25
Solution :
We'll solve this using the Pythagorean Theorem.Let,
Let BC be perpendicular.22 be AB, where AB is the Base.25 be AC, where AC is the Hypotenuse.We know that,
[tex]{ \longrightarrow \bf \qquad \: (AB) {}^{2} +( BC) {}^{2} = (AC) {}^{2} }[/tex]
[tex]{ \longrightarrow \sf \qquad \: (22) {}^{2} +( BC) {}^{2} = (25) {}^{2} } [/tex]
[tex]{ \longrightarrow \sf \qquad \: (BC) {}^{2} = (25) {}^{2} - ( 22) {}^{2} }[/tex]
[tex]{ \longrightarrow \sf \qquad \: BC = \sqrt{(25) {}^{2} - ( 22) {}^{2}} }[/tex]
[tex]{ \longrightarrow \sf \qquad \: BC = \sqrt{625 - 484} }[/tex]
[tex]{ \longrightarrow \sf \qquad \: BC = \sqrt{141} }[/tex]
[tex]{ \longrightarrow \bf \qquad \: BC \approx11.87 }[/tex]
Therefore,
The length of the third side is 11.9 (Nearest tenth of 11.87) .Step-by-step explanation:
According to Pythagoras theorem ,
Hypotenuse² = Perpendicular ² + Base ²
Here , we have to find perpendicular
Hypotenuse = 25 unitBase = 22 unitSo,
Hypotenuse² - Base² = Perpendicular²
putting the known values
25² - 22² = perpendicular²
141 = perpendicular²
√141 = perpendicular
Perpendicular = 11.9 unit

You mix 2/3 quart of blue paint for every 3/4 quart of red paint to make 4 and 1/4 quarts of purple paint. How much blue paint and How much red paint do you use?
Answer: 9/4 (or 2 and 1/4) quarts of red paint, & 2 quarts of blue paint.
Step-by-step explanation:
We know the amount of blue paint (2/3) is proportional to the amount of red paint (3/4).
Let's first add 2/3 and 3/4, that will make 17/12 quarts of purple paint. Call this a "serving".
The next step is to find out how many "servings" you need to make to make 4 and 1/4 quarts of purple paint.
4 and 1/4 = 17/4
17/4 divided by 17/12 = 3
Now we know the number of servings to make, which is 3.
Since 3/4 quarts of red paint is enough for one serving, we need to multiply this by 3. We can apply the same logic to the blue paint.
3/4 * 3 = 9/4
2/3 * 3 = 2

12. In PQR if mP is 14 less than five times x, mQ is five less than x, and mR is nine less
than twice x, find x and the measure of each angle.
Answer:
Step-by-step explanation:
mP=5x-14
mQ=x-5
mR=2x-9
we know that all the angles in a triangle= 180
that means (5x-14)+(x-5)+(2x-9)=180
5x-14+x-5+2x-9=180 we add the variables and the numbers
8x=180+28
8x=108
x=26
mP=130-14=116
mQ=26-5=21
mR=43
What is the simplified form of the fraction below 14/49
Answer:
That would be 2/7.
Step-by-step explanation:

Answer:
A, D, and F
Step-by-step explanation:
A. True, because represents a quadratic function (the greatest power of x is 2)
B. False, because this function is quadratic, so cannot be linear
C. False. The vertex of the parabola is at point (-7,4) (see diagram)
D. True. The axes of symmetry is the line x=-7 that passes through the vertex.
E. False. The y-intercept is at point x=0 and
F. True. The graph has the maximum at the vertex, where
G. False. The graph of the parabola intersects the x-axis at two points (-9,0) and (-5,0), so x=-9 and x=-5 are two real solutions of the equation f(x)=0.
