An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7.

If we recall that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, which lengths make sense for possible values of b?

Answer:

x= -4 y= -1

Step-by-step explanation:

6x - y = - 23

-y=-23-6x

y=6x+23, use this to plug in for y in the second equation.

2x + 5y = -13

2x + 5(6x+23) = -13

2x+30x+115=-13

x= -4, use this to plug in for x in the first equation.

6x - y = - 23

6(-4)-y=-23

-24-y=-23

-y=-23+24

-y=1

y= -1

The values after solving the equations by substitution is that the value of x is -4 and the value of y is -1.

The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the provided data in the question,

6x - y = -23  (i)

2x + 5y = -13  (ii)

Multiply equation (ii) by 3

6x + 15y = -39 (iii)

Solve equation (i) and (iii)

-16y = 16

y = -1

Substitute y = -1 in equation (i)

6x = -23 - 1

x = -4.

Answer:

see explanation

Step-by-step explanation:

(a)

There is a common difference d between consecutive terms, that is

d = 12 - 0 = 24 - 12 = 36 - 24 = 48 - 36 = 12

This indicates the sequence is arithmetic with common difference 12

(b)

To obtain the next term add 12 to the previous term, that is

48 + 12 = 60 and 60 + 12 = 72

The next 2 terms in the sequence are 60 and 72

Answer: D

Step-by-step explanation:

First, remember two things about translations.

For a function f(x).

A horizontal translation to the right of N units is written as:

f(x - N)

A vertical translation up of N units is written as:

f(x) + N.

Now let's look at the graph.

You can see that:

g(x) is: 4 units at the right of f(x) and 3 units bellow f(x).

Then we have:

g(x) = f(x - 4) - 3.

and f(x) = ∛x

then g(x) = ∛(x - 4) - 3

The correct option is D.

The function g(x) is transformed from the function f(x) by translating function f(x) by 4 units in the right direction and then by translating that graph 3 units in a downward direction.

Given :

Function --   [tex]\rm f(x) = \sqrt[3]{x}[/tex]

The following steps can be used to determine the unknown function g(x):

Step 1 - According to the given graph, translate function f(x) 4 units in the positive x-axis that is in the right direction.

Step 2 - Now, again according to the given graph, translate function f(x) 3 units in the downward direction that is in the negative y-axis.

Step 3 - The resulting graph is the graph of the function g(x). Whose equation is written as:

[tex]\rm g(x) = \sqrt[3]{x-4} - 3[/tex]

So, the correct option is D).

Answer:

60 cm

Step-by-step explanation:

remember, the area of a triangle is found by

1/2 b h

or half of the base times the height

so using that plug in the values:

the base is made of two 5s;  2* 5 is 10 so the base is 10cm long

the height is 12cm

so

1/2 * 12 * 10

= 6 * 10

= 60

Answer:

I think its 60

Step-by-step explanation:

To find the area of a triangle you do (height x base) divided by 2

5+5=10

12 x 10 = 120

120 divided by 2 is 60

Answer:

The number of rabbits Katniss caught = 10 rabbits

Step-by-step explanation:

The number of squirrels Katniss caught = 3 × (The number of deer she caught)

The number of rabbits Katniss caught = The number of squirrels she caught - 5

The total number of animals she caught = 10 + 4 × (The number of deer she caught)

Let the number of deer Katniss caught = D

∴ The number of squirrels she caught = 3×D

The number of rabbits Katniss caught =  3×D - 5

The total number of animals she caught = 10 + 4 × D

Therefore, we have;

The number of squirrels she caught + The number of deer she caught + The number of rabbits she caught = 10 + 4 × D

3×D + D + 3×D-5 = 10 + 4 × D

7·D - 5 = 10 + 4·D

7·D - 4·D = 10 + 5

3·D = 15

D = 15/5 = 5

∴ The number of deer Katniss caught = D = 5

The number of rabbits Katniss caught =  3×5 - 5 = 10

The number of rabbits Katniss caught = 10 rabbits.

Step-by-step explanation:

From Question, we are told that, there are 14 rows of seat with is divided into left hand side and right hand side

Seats by the right = fit two people

Seats by the left = fit three people

This means, 1 row of seat can contain 5 persons

The back seat = 8 people can sit comfortably.

Hence, the number of people that can ride the bus at one time =

(14 × 5 people) + 8 people (backseat) + 1 driver

= 70 + 8 + 1

= 79 people
