Solve for x. Enter the solutions from least to greatest.
(x+15)^2-10=0
Answer:
lesser x = -1.84lesser x = -8.16Step-by-step explanation:
Given the expression
[tex]\left(x+5\right)^2-10=0[/tex]
Add 10 to both sides
[tex]\left(x+5\right)^2-10+10=0+10[/tex]
Simplify
[tex]\left(x+5\right)^2=10[/tex]
[tex]\mathrm{For\:}\left(g\left(x\right)\right)^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
solve
[tex]x+5=\sqrt{10}[/tex]
Subtract 5 from both sides
[tex]x+5-5=\sqrt{10}-5[/tex]
[tex]x=\sqrt{10}-5[/tex]
[tex]x=-1.8[/tex]
so
[tex]x+5=-\sqrt{10}[/tex]
Subtract 5 from both sides
[tex]x+5-5=-\sqrt{10}-5[/tex]
Simplify
[tex]x=-\sqrt{10}-5[/tex]
[tex]\:x=-8.2[/tex]
As -1.84 > -8.16
so
lesser x = -1.84lesser x = -8.16Find the length of side A

A student observes a difference in the activity level of fish at a pet store. The fish in an aquarium near the window are swimming around more quickly tha the fish in an aquarium placed in the back of the store. The student forms a hypothesis about the effect of sunlight on fish activity levels and arranges to conduct an experiment. Which variable could be an independent variable in the student's experiment? types of fish sold speed of swimming fish amount of time fish were active temperature of water in fish tank
Answer: Types of fish sold
The type of fish sold is the independent variable in the student's experiment. So, the correct option is (A).
What are Variables?
A variable is any kind of characteristic, number, or quantity which can be measured or counted. It can also be called a data item. Examples of variables are age, sex, occupation income and expenses, country of birth, capital expenditure, class grade, eye color, and vehicle type.
There are two types of Variables are:
1. Dependent variable
A dependent variable is a type of variable which changes as the result of independent variable manipulation which is the outcome interested in measuring, and it "depends on" the independent variable.
2. Independent variable
An independent variable is the type of variable which is manipulated or varied in an experimental study in order to detect its effects. This is "independent" because it is not affected by any other variable in the study.
In above case, this is independent because types of fish characteristic is not dependent for the experiment.
Thus, the type of fish sold is the independent variable in the student's experiment. So, the correct option is (A).

Rearrange x = 3g + 2 to make g the subject g=?
Step-by-step explanation:
x=3g+2
you need to move the equation to the other side, first you'd start with the one furtherest from g, which is is 2.
x = 3g
-2. - 2
and minus it from both sides
x-2=3g
3g is like 3x, which is 3 times x and you need to use the opposite operators so times would become divide.
so now it becomes x-2 over 3=g

Find the slope of the line through (9, 4) and (0, 5).
Answer:
It's just y2-y1 over x2-x1
Step-by-step explanation:
so pick a coordinate and make it 1 and make the other one 2 and put in the numbers.
The slope of the line will be m = -1/9.
What is the general equation of a Straight line?The general equation of a straight line is -y = mx + c
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis
Other possible equations of line are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have a line through (9, 4) and (0, 5).
The slope of the line will be -
[m] = (4 - 5)/(9 - 0)
[m] = - 1/9
Therefore, the slope of the line will be m = -1/9.

In a fruit punch drink, the 3 ingredients are apple juice, orange juice and cranberry juice. If
1/4 of the drink is apple juice and
2/5 is orange juice then write the ratio of cranberry juice to apple juice to orange juice in its simplest form
Answer:
[tex]Cranberry:Apple:Orange = 7:5:8[/tex]
Step-by-step explanation:
Given
[tex]Apple = 1/4[/tex]
[tex]Orange = 2/5[/tex]
Required
Determine the ratio of Cranberry to Apple to Orange
First, we calculate the fraction of Cranberry using:
[tex]Cranberry + Apple + Orange = 1[/tex]
Substitute values for Apple and Orange
[tex]Cranberry + 1/4+ 2/5= 1[/tex]
Collect Like Terms
[tex]Cranberry = 1- 1/4- 2/5[/tex]
Take LCM
[tex]Cranberry = \frac{20 - 5 - 8}{20}[/tex]
[tex]Cranberry = \frac{7}{20}[/tex]
The ratio is then represented as:
[tex]Cranberry:Apple:Orange = 7/20:1/4:2/5[/tex]
Multiply through by 20
[tex]Cranberry:Apple:Orange = 20(7/20:1/4:2/5)[/tex]
[tex]Cranberry:Apple:Orange = 20*7/20:20*1/4:20*2/5[/tex]
[tex]Cranberry:Apple:Orange = 7:5:8[/tex]

Find the value of x.
A. 18
B. 22
C. 24
D. 28
Answer:
A
Step-by-step explanation:
Using Pythagoras' identity on the large right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
(x + 32)² = 30² + 40² = 900 + 1600 = 2500 ( take the square root of both sides)
x + 32 =[tex]\sqrt{2500}[/tex] = 50 ( subtract 32 from both sides )
x = 18 → A
Find the sum of 4x^2-4x+104x

+5x−8.
The sum of the expression 4x^2-4x+10 and the expression 2x^2+5x-8 is 6x^2+x+2 because the sum of the x^2 term is 6, the sum of the x term is 1, and the sum of the constant term is 2.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have:
First expression:
[tex]\rm 4x^2-4x+10[/tex]
Second expression:
[tex]\rm 2x^2+5x-8[/tex]
Let's denote the sum of these two expressions with F(x)
[tex]\rm F(x) = \rm 4x^2-4x+10+\rm 2x^2+5x-8\\\\\\\rm F(x) = 6x^2+x+2[/tex]
Thus, the sum of the expression 4x^2-4x+10 and the expression 2x^2+5x-8 is 6x^2+x+2 because the sum of the x^2 term is 6, the sum of the x term is 1, and the sum of the constant term is 2.
