please help me I’m struggling :( , sorry about it being sideways.

Answer:

Step-by-step explanation:

This is part of the Isosceles Triangle Theorem. If one theta is equal to the other theta (and they are or else they wouldn't both be theta; one would be theta and the other might be beta), that means that the sides across from those congruent angles are also congruent. That means that

6x + 6 = 9x - 9 and

15 = 3x so

x = 5

Answer: y = 3

Step-by-step explanation:

14/y - 2/3 = 4

14/y = 4 + 2/3

14y = 14/3

y = 3

Answer:

2(14x +15)

Answer:

option c

Step-by-step explanation:

Answer: 9/4a^2|b^3|c^4

Step-by-step explanation:

81/16

Square root(81) = 9

Square root(16) = 4

9/4

Since 4 is the index of the radical, all of the exponents divide by 4

(index 4)a^8 = a^2

(index 4)b^12 = b^3

(index 4)c^16 = c^4

Now put the variables together to get the answer:

9/4a^2|b^3|c^4

Answer:

The expression 7x represents the height of the container.

Step-by-step explanation:

From the question:

We are being informed that; if the length of the container is half of a foot longer than its width.

Let the width be x;

Then the length of the container can now be ; x+1/2

We all known that the volume of a rectangular prism is : V= l×w×h

here;

l = length

w = width

h = height  

If we rewrite the given expression :

[tex]\mathbf{7x^3+3.5x^2}[/tex];

Then we factor we make a similar coefficient  of  the above equation, the  remaining entities left in the parenthesis should be a linear term  with a leading coefficient of 1 to match the expression for the length of the container.

i.e

[tex]\mathbf{7x^3+3.5x^2}} \\ \\\mathbf{7x^2(x+1/2)} \\ \\\mathbf{7*x*x*(x+1/2)}[/tex]

Hence, if the length of the container is half a foot longer than its width, x, then the expression 7x represents the height of the container.

Answer:

(- 2, 0 )

Step-by-step explanation:

Given

y = 2x² + 2x - 4

To find the x- intercepts let y = 0, that is

2x² + 2x - 4 = 0 ( divide through by 2 )

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

x- intercepts are x = - 2, x = 1, that is

(1, 0 ) and (- 2, 0 )

The other x- intercept is (- 2, 0 )

Answer: 340 cm3  

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:  

Circumference = 2π radius

Replacing with the circumference value and solving for r:

31.416 =2π r

31.416 /2π =r

5cm =r

And then:

Volume of a cone = 1/3 x π x radius^2 x height  

Replacing with the values given:  

V = 1/3 π (5)^2 (13) = 340 cm3

Answer:

turkey: $3.50

ham: $3

Step-by-step explanation:

Use system of equations:

turkey-x   ham-y

5x+7y=38.5

4x+6y=32

multiply by 4 on equation 1 and multiply by 5 on equation 2

20x+28y=154

20x+30y=160

-2y=-6

y=3 ham is $3

5x+7(3)=38.5

5x=38.5-21

5x=17.5

x=3.5 turkey is $3.50

Answer:

A&D

Step-by-step explanation:

Lines with the same slope are parallel. 2x-5 and 2x+5 have the same slope

Answer:

A and D are parallel.

Step-by-step explanation:

Refer to the slope-intercept equation (y = mx + b).

M = the slope

If the slopes are equal, then the lines are parallel.

The slope for line A is 2, and so is the slope for line D.

Line A and line D are parallel.

Answer:

Well I can't exactly graph for you but I will tell you the y intercept is at (0,-3) and the slope is -5/4

Step-by-step explanation:

Make a graph and plot a point on (0,-3)

Then go down 5 and go right 4 to represent the slope of -5/4

Hope this helps!

The graph of line y= -5/4x -3 is attached below.

We have the equation

y= -5/4x - 3.

To graph the line y = -5/4x - 3, you can use the slope-intercept form of a linear equation, which is y = mx + b.

In this equation, "m" represents the slope, and "b" represents the y-intercept.

From the given equation, we can determine that the

slope (m) is -5/4, and the y-intercept (b) is -3.

The graph of the line y = -5/4x - 3 should look like a downward-sloping line that passes through the points (0, -3), (4, -8), and (-4, -2).

Answer: 40

ADE = 70 por suma de angulos interiores en triangulo ADE

En triangulos BDE y AED

AE=BE por dato

DE lado comun

AED= BED= 90

por tanto los triangulos son iguales por tener dos lados y el angulo comprendido respectivamente iguales

Luego ADE = BDE = 70 y AD=BD=BC por ser triangulos BDE y AED iguales

Luego triangulo BDC isosceles de base DC

ADE + BDE + BDC = 180 por suma de angulos consecutivos

BDC = 180 - 70 -70 = 40

Ф = BDC =BCD = 40 por ser angulos bases de un triangulo isosceles

Answer:

see below

Step-by-step explanation:

a) see attached chart

b) sum is 10

There are 3 that total to 10  (4,6)  (5,5) and (6,4)  and there are 36 possible outcomes

P(10) = number of outcomes that sum to 10 / total number of outcomes

        =3/36

        = 1/12

c) identical numbers  There are 6 that are identical (1,1) (2,2) (3,3) (4,4) (5,5) (6,6)

p(identical) = number of outcomes that are identical / total number of outcomes

        =6/36

        = 1/6

d product a multiple of 10 ( 5,2)  (5,4) (5,6)  (2,5)  (4,5) (6,5) are the only ones with a product multiple of 10

p(identical) = number of outcomes that are identical / total number of outcomes

        =6/36

        = 1/6
