Answer:

7 times a number increased by 4 times the number

Let a number and the number be an arbitrary variable. Let's call it x. We have an algebraic expression. Let's take it in pieces:

7 times a number: 7x

4 times the number: 4x

The phrase increased by means we add 4x to 7x:

7x + 4x

Simplifying, we get: (7 + 4)x

11x

Answer: Lydia used 1/3 pound of peppers and 1/10 pound of cheese to make 3 pizzas, which means that she used 1/3 / 3 = 1/9 pound of peppers and 1/10 / 3 = 1/30 pound of cheese per pizza.

If Lydia uses the same recipe to make 1 pizza, she will need 1/9 pound of peppers and 1/30 pound of cheese. Therefore, the amount of cheese needed is 1/30 pound.

The value of y is 130°

The angles occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

Given here:

Horizontal and parallel lines b and c are cut by transversal a. At the intersection of lines b and a, the bottom right angle is 50 degrees. At the intersection of lines c and a, the top left angle is y degrees.

Thus the angle adjacent to the 50-degree angle will be 130

but this angle corresponds to the angle y thus y=130 as corresponding angles are equal when a transversal intersects two parallel lines

Hence, The value of y is 130°

The value of x and y in equations 17x - y = 40 and 2x + 4y = 50 are x = 3 and y = 11.

What is equation ?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.

17x - y = 40  ⇒ (1)

2x + 4y = 50 ⇒ (2)

(1)* 4

68x - 4y = 160

Adding equation (1) and (2)

68x - 4y = 160

2x + 4y = 50

⇒ 70 x = 210

        x = 3

Substituting the value of x in equation (1)

17*3 - y = 40

51 - y = 40

-y = 40 - 51

-y = -11

y = 11

Expression: x² - 6x + 9

Factored form: (x - 3)²

Using the concept of factorization.

The breaking or breakdown of an entity (such as an integer, a matrix, or even a polynomial) into such a combination of some other unit, or factors, whose multiplication yields the original number, matrix, etc., is known as factorization or factoring in mathematics.

Similarly to this, factoring is a very useful technique in algebra that is utilized at all levels. Additionally, to, of course, simplify complex expressions, it offers a standard way for solving quadratic equations. Graphing functions also makes advantage of it.

Factor the expression, put each factor equal to 0, and then solve each equation to solve a quadratic equation by factoring. To do this, rearrange all terms on one side of the equation such the other side equals 0.

Given that,

x² - 6x

Now, to find the value of c = (b/2)²

divide the coefficient of x by 2.

So, divide 6 by 2 we get: ( -1.3)²

Next, multiply -1 by 3: (-3)²

Now, raise -3 to the power of 2, we get: 9

So, the expression becomes: x² - 6x + 9

Factorized form: (x - 3) (x -3)

or we can write (x - 3)²

Given:

The graph of a quadratic function passes through the points (5,31) (3,11) (0,11).

To find:

The equation of the quadratic function.

Solution:

A quadratic function is defined as:

[tex]y=ax^2+bx+c[/tex]            ...(i)

It is passes through the point (0,11). So, substitute [tex]x=0,y=11[/tex] in (i).

[tex]11=a(0)^2+b(0)+c[/tex]

[tex]11=c[/tex]

Putting [tex]c=11[/tex] in (i), we get

[tex]y=ax^2+bx+11[/tex]               ...(ii)

The quadratic function passes through the point (5,31). So, substitute [tex]x=5,y=31[/tex] in (ii).

[tex]31=a(5)^2+b(5)+11[/tex]

[tex]31-11=a(25)+5b[/tex]

[tex]20=25a+5b[/tex]

Divide both sides by 5.

[tex]4=5a+b[/tex]                  ...(iii)

The quadratic function passes through the point (3,11). So, substitute [tex]x=3,y=11[/tex] in (ii).

[tex]11=a(3)^2+b(3)+11[/tex]

[tex]11-11=a(9)+3b[/tex]

[tex]0=9a+3b[/tex]

Divide both sides by 3.

[tex]0=3a+b[/tex]                 ...(iv)

Subtracting (iv) from (iii), we get

[tex]4-0=5a+b-3a-b[/tex]

[tex]4=2a[/tex]

[tex]\dfrac{4}{2}=a[/tex]

[tex]2=a[/tex]

Putting [tex]a=2[/tex] in (iv), we get

[tex]0=3(2)+b[/tex]

[tex]0=6+b[/tex]

[tex]-6=b[/tex]

Putting [tex]a=2,b=-6[/tex] in (ii), we get

[tex]y=(2)x^2+(-6)x+11[/tex]

[tex]y=2x^2-6x+11[/tex]

Therefore, the required quadratic equation is [tex]y=2x^2-6x+11[/tex].

Answer:

-3w2-11w-3

Step-by-step explanation:

take w2 and w as variables. you can substitute it as w2=y and w=X then expand brackets

2y-8x-8-5y-3x+5

note that the signed changed at the second part because it was expanded with the minus sign which is basically like -1, so it changes the signs

then you collect like terms:

2y-5y-8x-3x-8+5= -3y-11x-3

now put substitute back w2=y and w=X

-3w2-11w-3

if it won't be a problem solving with w2 and w, then you skip the substitution part and solve the same

x = 15

Step-by-step explanation:

The height of the rock ledge will be 20.35 meters.

The height of the tree will be 58.75 meters

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The angle of elevation to the top of a tree is 22°.

And, The angle of depression to the base of the tree is 12°.

Now,

Let the height of the rock ledge = x

So, By figure, we get;

⇒ tan 12° = x / 96

⇒ x = 96 × tan 12°

⇒ x = 20.35 meters

And, Let total height of the tree = x + y

                                                = 20.35 + y

Hence, By figure, we get;

⇒ tan 22° = y / 96

⇒ y = 96 × tan 22°

⇒ y = 96 × 0.40

⇒ y = 38.4 meter

Thus, The height of tree = 38.4 meters + 20.35 meters

                                      = 58.75 meters

To find:-

Answer:-

Part A :-

Here we can see that the distance between the rock ledge and the base of the tree is 96m . Also the angle of elevation to the top of the tree from the rock is 22° .

Firstly, we can see that,

[tex]\implies \angle CAD =\angle EDA = 12^o\\[/tex]

This is so because they are alternate interior angles .

Now , in ∆ADE ,

[tex]\implies \tan\theta =\dfrac{p}{b}=\dfrac{AE}{ED}\\[/tex]

[tex]\implies \tan 12^o =\dfrac{AE}{96m} \\[/tex]

[tex]\implies AE = 96\tan12^o m \\[/tex]

[tex]\implies AE = 96 (0.21)m \\[/tex]

[tex]\implies AE = 20.16 \ m \\[/tex]

Hence the height of the rock ledge is 20.16 m.

_______________________________________

Part B :-

Now in ∆ACB , we have;

[tex]\implies \tan\theta =\dfrac{BC}{AC} \\[/tex]

[tex]\implies \tan 22^o =\dfrac{BC}{96m} \\[/tex]

[tex]\implies BC = 96\tan 22^o \ m \\[/tex]

[tex]\implies BC = 96(0.4) m \\[/tex]

[tex]\implies BC = 38.4 \ m \\[/tex]

Now the total height of the tree will be = BC + AE

[tex]\implies h_{tree}= BC + AE \\[/tex]

[tex]\implies h_{tree}=38.4\ m + 20.16 \ m =\boxed{58.56\ m} \\[/tex]

Hence the height of the tree is 58.56m.

and we are done!
