Answer:

176 yd

Step-by-step explanation:

UNSHADED REGION (white rhombus): A=(s1+s2)/2 * H

s1=7

s2=1+7=8

H=6

A=(7+8)/2*6=45

SHADED + UNSHADED REGION (big parallelogram): area of parallelogram A=B*H

B=17

H=7+6 = 13

A=17*13=221

SHADED REGION: big parallelogram area - rhombus area

221 - 45 =176 yd

Answer: x = 65

Step-by-step explanation:

1) First find the mini triangles, left and right angles

We will be calling the left one A and the right one B.

2) Next use triangle sum to find B.

62 + 50 + b = 180

b = 68

3) Use triangle sum again to find A.

53 + 80 + a = 180

a = 47

4) Use triangle sum to find the top mini angle.

47 + 68 + c = 180

c = 65

5) Since x is in the vertical angle of c, they are equal

c = x

65 = x

The variable y is shown with no exponent. Any term with no exponent is understood to have an exponent of 1, so y has an exponent of 1.

The solution for the given inequality is p < -2.2. The graph that represents the solution is attached below.

From the question, we are to determine the graph for the solution set for the given inequality

The given inequality is p - 3.6 < -5.8

First, we will solve the inequality

Solving the inequality

p - 3.6 < -5.8

Add 3.6 to both sides

p - 3.6 + 3.6 < -5.8 + 3.6

p < -2.2

The solution is p < -2.2

The required value of the function at x = 4 and 3 is f(4) = -12 and f(3) = -7.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Given function ,

f(x) = 8 - 5x
put x = 4
f(4) = 8 - 5(4)
f(4) = 8 - 20
f(4) = -12

Again,
put x = 3
f(3) = 8 - 5(3)
f(3) = 8 - 15
f(3) = -7

Thus, the required value of the function at x = 4 and 3 is f(4) = -12 and f(3) = -7.

Eric will spend $84
I calculated it by seeing how much each of the pizzas cost-$7 the I figure out how many pizzas he need-12 Now what we need to do is multiply 7 and 12 because if one pizza is $7 (Stated in the written problem) then I know that it would be 7+7+7+7+7+7+7+7+7+7+7+7 12 times, one time for each pizza needed. The simpler version would be 7 time 12 which then we would get a value of $84.

Algebraic equations are mathematical equations that consist of unknown variables. These unknown variables can be represented with any letter of the alphabet.

The cost of 2 pounds(lb) of the first type of candy is $8

Note that: x represents the cost per pound (lb) of the first type of candy

The Algebraic equation for the above statement is given as:

2lb × $x + 3 Ib × $1.50 = $2.50(2lb + 3lb)

2x + 4.5 = 12.5

Collect like terms

2x = 12.5 - 4.5

2x = 8

Divide both sides by 2

2x/2 = 8/2

x = 4

The cost of the 1 pound of first type of candy is $4

The cost of 2 pounds(lb) of the first type of candy is calculated as:

2 x $4

= $8

Answer:

x = 60

Step-by-step explanation:

(2x + 15)° and 135° are corresponding angles and are congruent , then

2x + 15 = 135 ( subtract 15 from both sides )

2x = 120 ( divide both sides by 2 )

x = 60

Answer:

x = 60

Step-by-step explanation:

The two angles are corresponding. This means that both of the angles are congruent (same). So, you set both of them equal to each other. That means to do 2x + 15 = 135. You do basic algebra and then you get 60 for x. Hope this helps!

Answer:

y - intercept is (0,2)

x - intercept is (3,0)

Step-by-step explanation:

This is standard form.  

Let x  = 0

2x + 3y = 6

2(0) + 3y = 6

3y = 6   Divide both sides of the equation by 3

y  = 2

The y intercepts is (0,2)

Let y = 0

2x + 3(0) = 6

2x = 6  Divide both sides of the equation by 2

x = 3

The x intercept is (3,0)

Answer:

x-intercept (3, 0)

y-intercept (0, -2)

Step-by-step explanation:

        At x-intercept the y = 0. The line passes the x-axis.

             2x  -0 = 6

                   2x = 6

                     x = 6 ÷ 2

                     x = 3

x-intercept (3, 0)

At y-intercept, x = 0 . The line passes y-axis.

      0 - 3y = 6

        -3y  =  6

           y =  6 ÷ (-3)

           y = (-2)

y-intercept (0 , -2)

Then,

T = Painting from 20th century

Here,

Probability = British/ Its from 20th century

Probability = n (B and T) / n(T)

                  = x / (x + x(x-2))

The polynomial is x³ + 2x

If the zeros or roots of the polynomial are given, then the standard form of the polynomial can be found.

That is, a, b and c are roots of the polynomial, then  the polynomial will be of degree 3 since 3 zeros are there and the factors of the polynomial will be , x-a, x-b and x- c.

Then the polynomial is, (x-a)(x-b)(x- c) = x³-(a+b+c)x-abc

Here the zeros of the polynomial are x = 0, x = i√2 and x = -i√2.

So the factors of the polynomial are (x-0), (x - i√2) and (x +i√2).

In accordance with analytic geometry, the equation that represents the line is y = - (1 / 4) · x - 6.

Herein we find the representation of a line set on a Cartesian plane. According to analytic geometry, line are represented by equations of the form y = m · x + b, where m, b are the slope and the y-intercept, respectively.

Both the values of the slope and the y-intercept can be found by knowing the location of two points lying on the line. If we know that (x₁, y₁) = (0, - 6) and (x₂, y₂) = (4, - 7), then we find the following system of linear equations:

b = - 6                                    (1)

4 · m + b = - 7                        (2)

By (1) in (2):

4 · m - 6 = - 7

4 · m = - 1

m = - 1 / 4
