Answer: x=1

Step-by-step explanation:

x - 4 -5 = -8      combine like terms on the left side

x - 9 = - 8      Add 9 to both sides

    +9    +9

x = 1

Use the parabola tool to graph the quadratic function f(x)=−12x2+7. Graph the parabola by first plotting its vertex and then plo
Fudgin [204]
First we find the vertex of parabola f(x)=-12 x^{2} +7

The vertex of parabola is ( \frac{-b}{2a},f( \frac{-b}{2a}))
Here,
b = coefficient of x term
a = coefficient of x² term

For given parabola, b = 0 , a = -12

So,
\frac{-b}{2a}= \frac{0}{-24} =0

And,

f( \frac{-b}{2a} )=f(0) = -12(0)+7=7

Thus the vertex of parabola is (0, 7)

To find another point on parabola, substitute x by 1.

f(1)=-12( 1^{2}) +7=-12+7=-5

So the second point on parabola is (1,-5)

The plot of parabola is shown in image below:

23j-21g+20e-13+52e-37j+45-49e<br> (Like terms)
eduard

The solution to the algebraic expression is: 23e - 21g - 14j + 32

What are algebraic expressions?

Algebraic expressions are mathematical expressions that contain variables, coefficients, and arithmetic operations such as addition, subtraction, division, and multiplication.

Solving algebraic expressions are an important part of mathematics as it helps to improve the aptitude and solving skills of the students.

From the given information, we have;

23j - 21g + 20e - 13 + 52e - 37j + 45 - 49e

let's rearrange by taking the like terms to the same sides;

= 23j -37j - 21g + 20e + 52e - 49e - 13 + 45

= -14j - 21g + 23e + 32

= 23e - 21g - 14j + 32

Therefore, we can conclude that the solution to the algebraic expression is: 23e - 21g - 14j + 32

Jarvis left out a statement from the proof shown.which statement is best explained by the corresponding angles postulate
Salsk061 [2.6K]
The postulate of the corresponding angles establishes that when a transversal line cuts two parallel lines, the corresponding angles are congruent. These angles are on the same side of the parallel lines and on the same side of the transversal line.

  Then, if we based on this definition and analize the figure attached, we can notice that the angles ∠1 and ∠3 are corresponding angles, so they are congruent. In this case the angle ∠1 is internal and the angle ∠3 is external.

 The answer is: ∠1 and ∠3 are congruent (See the image attached).
