Answer:
x = 9
Step-by-step explanation:
Let's solve your equation step-by-step.
[tex]x=\sqrt{x+7} +5[/tex]
Step 1: Flip the equation.
[tex]\sqrt{x+7} +5=x[/tex]
Step 2: Add -5 to both sides.
[tex]\sqrt{x+7} +5-5=x-5[/tex]
Step 3: Solve Square Root.
[tex]\sqrt{x+7} =x-5[/tex]
[tex]{x+7} =(x-5)^2[/tex] (Square both sides)
[tex]x+7=x^2-10x+25[/tex]
[tex]-x^2+11x-18=0[/tex]
[tex](-x+2)(x-9)=0[/tex] (Factor left side of equation)
[tex]-x+2=0[/tex] or [tex]x-9=0[/tex] (Set factors equal to 0)
x = 2 or x = 9
x = 2 (Doesn't work on the original equation)
x = 9 (Works in the original equation)
Answer:
x = 9

Jollibee employs a total of 10 cashiers and 15 kitchen crews. The manager selects a team of 2 cashiers and
4 kitchen crews for a graveyard shift. In how many ways can the manager select a team?
Answer:
The manager can select a team in 61425 ways.
Step-by-step explanation:
The order in which the cashiers and the kitchen crews are selected is not important. So we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In how many ways can the manager select a team?
2 cashiers from a set of 10.
4 kitchen crews from a set of 15. So
[tex]T = C_{10,2}*C_{15,4} = \frac{10!}{2!(10-2)!}*\frac{15!}{4!(15-4)!} = 45*1365 = 61425[/tex]
The manager can select a team in 61425 ways.

The first three terms of a geometric sequence are as follows.
-7, 14, -28
Find the next two terms of this sequence.
Give exact values (not decimal approximations).
-7, 14, -28, CI
-7,14,-28,56,-112
an = a1(r)^n-1
a4 = -7(-2)^4-1
a4 = -7(-2)³
a4 = -7(-8)
a4 = 56
an = a1(r)^n-1
a5 = -7(-2)^5-1
a5 = -7(-2)⁴
a5 = -7(16)
a5 = -112

Find the area of the rhombus
Answer:
area of rhombus=d1×d2=1/2(5+5)×(10+10)=1/2 10×20=100m²
The area of the rhombus is 100 m².
We have,
The area of a rhombus.
Area = (diagonal A* diagonal B) / 2 _____(1)
Now,
From the figure,
Diagonal A = (5 + 5) = 10 m
Diagonal B = (10 + 10) = 20 m
Substitute the values in (1).
Area of the rhombus.
= 1/2 x (10 x 20)
Simplify the expression.
= 1/2 x 200
= 100 m²
Thus,
The area of the rhombus is 100 m².

Over a two hour time period a snail moved 50 inches. How far is this in yards? Write your answer as a whole number or a mixed number in simplest form. Include the correct unit in your answer.
Answer:
1.3 yards
Step-by-step explanation:
Answer:
1 7/18 yards or 1 14/36 yards.
Step-by-step explanation:
There are 36 inches in a yard, so you divide 50 by 36.
You get a variety of answers depending on what form you want it in:
1 yard 1 foot and 2 inches.
1 yard and 14 inches.
These two answers take two forms as fractions of 36:
1 14/36 yards
or simplified: 1 7/18 yards.

Answer
the answer is 90 (C)
Step-by-step explanation:
Beth = x
Caroline = 60 + x (because if Beth has 60 less than Caroline then Caroline has 60 more than Beth)
Since the ratio = 1/3 ( another way of writing 1:3) then x/60+x = 1/3
3x = 60 + x
3x - x = 60
2x = 60
x = 60/2
x = 30 (Beth has 30 stickers)
Caroline has 60 + x stickers = 60 + 30 = 90

the graph represents the x^2+y^2=8. Use the graph to answer questions 6,7,8.
6. look at the graph of the equation x^2+y^2=8. give its domaim and range
7. use algebraic means to show that x^2+y^2=8 is not a function. Explain your process.
8. is there any value(s) of the domain of x^2+y^2=8 that passes the verticle line test? if so, name the value(s) and state whether or not the existence of this value makes this relation a function. You can use Desmos to help you explore this idea, if needed.
Using the concepts of domain and range, we have that:
6. Both the domain and the range of the relation are [-2.826, 2.826].
7. The relation is not a function, as each value of x is associated with two values of y, that is: [tex]y = \pm \sqrt{8 - x^2}[/tex].
8. From item 7, we get that there are no points that pass the vertical line test.
What are the domain and the range of a function?The domain of a function is the set that contains all the values of the input. In a graph, it is represented by the values of x.The range of a function is the set that contains all the values of the output. In a graph, it is represented by the values of y.Hence, from the graph of the circle, for item 6, both the domain and the range of the relation are [-2.826, 2.826].
A relation is a function only if each value of x is related to only one value of y. Solving the equation of the circle for y, we have that:
x² + y² = 8.
y² = 8 - x²
y = ±sqrt(8 - x²).
Hence each value of x is related to two values of y, meaning that it is not a function, and for item 8, there are no points that pass the vertical line test.

Is the radius or diameter given? diameter
The area of the cirle is :
32 in
Answer:
The area of the circle is 100.48; the diameter is shown.
Step-by-step explanation:
The formula for finding the area of a circle is 3.14 (or pi) multiplied by the diameter. 3.14*32= 100.48
The radius is half of the diameter, or half of the circle. However, this drawing shows the whole distance of the circle, so the diameter is shown.
