I need the answer
Your answer would be x = -1.
We can find this by first expanding the brackets on both sides of the equation:
4x + 8 = 6x + 10
Now we can rearrange and solve for x:
4x + 8 = 6x + 10
- 4x
8 = 2x + 10
- 10
-2 = 2x
÷ 2
-1 = x
I hope this helps!
Answer:
x = - 1
Step-by-step explanation:
Given
4(x + 2) = 2(3x + 5) ← distribute parenthesis on both sides
4x + 8 = 6x + 10 ( subtract 6x from both sides )
- 2x + 8 = 10 ( subtract 8 from both sides )
- 2x = 2 ( divide both sides by - 2 )
x = - 1

Answer:
x = ± 2
Step-by-step explanation:
To find the zeros set the polynomial equal to zero, that is
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
Thus x = - 2 or x = 2
what is the equation of the line?
Answer:
x=3
Step-by-step explanation:
try different values on the line! plug them in and you'll see that every x value is 3!
Answer:
x=3
Step-by-step explanation:
Because there is no slope (or the slope is undefined), there is another way to write the equation. Instead of y=mx+b, it will be either x=b or y=b, y=b being a horizontal line and x=b being vertical. To find b, simply find the value of x or y. The line has infinite points on it with one similarity, being their x value is 3. Hence, the equation is x=3.

The student council at Richmond High School
is made up of 646 female students 229
seniors, and 6% female seniors.
If a student is selected at random, what is the
probability, as a decimal to the nearest
hundredth, that the student is female given that
the student is a senior?
Answer:
[tex]P(F/S)=0.216[/tex]
Step-by-step explanation:
Let's call F the event that the student is female and S the event that the student is senior.
So, we need to find the probability P(F/S) that a student is female given that the student is a senior. P(F/S) is calculated as:
P(F/S) = P(F∩S)/P(S)
Then, the probability P(F∩S) that a student is female and senior is equal to 0.06
On the other hand, we can calculate the total number of students x using the following equation as:
[tex]\frac{646}{x}+\frac{229}{x}-0.06=1[/tex]
Where 646/x is the percentage of female students, 229/x is the percentage of senior students and 0.06 is the percentage of female seniors.
Then, solving for x we get that the number of students is 825.4719
Additionally, the probability P(S) that a student is a senior is equal to:
[tex]P=\frac{229}{825.47} =0.2774[/tex]
Because there are 825.47 students and 229 are senior.
So, P(F/S) is equal to:
[tex]P(F/S)=\frac{0.06}{0.2774}=0.216[/tex]

Step-by-step explanation:
There are many variables that affect the calculation of a patient’s total blood volume. For the purposes of this question, weight and age will be the only variables considered. The Australian Red Cross states that “Blood volume can be estimated as approximately 70mL/kg for adults, 80mL/kg in children…”. Work on the assumption that an adult is a person aged 16 years or over and a child is a person aged 2 to 16 years.
Let:
W = Weight (kg)
P = Plasma volume (mL) and
T = Total blood volume (mL)
Write 2 equations for calculating Total blood volume (T) given Weight (W), expressing T in terms of W, one for adults and one for children:
Answer:
The two equations are;
For adults, T = W kg × 70 mL/kg ............Equation (1)
For children, T = W kg × 80 mL/kg.............Equation (2)
Step-by-step explanation:
We are told that
Blood volume = 70 mL/kg for adults
Blood volume = 80 mL/kg in children
Therefore, the total blood volume,T of an adult of weight, W is given by the following relation;
T = W kg × 70 mL/kg ............Equation (1)
The total blood volume,T of a child of weight, W is given by the following relation;
T = W kg × 80 mL/kg.............Equation (2).
Tarzan is swimming east at 2.4 m/s across a river that is 1660 meters wide and
flows north at 5.2 m/s
What is tarzan’s final rate of swimming?
Tarzan’s final rate of swimming is 4.83 minutes.
What is velocity?Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference.
Now it is given that,
Tarzan is swimming east at Velocity, Vt = 2.4 m/s
River's Velocity flowing north, Vr = 5.2 m/s
Width of river = 1660 meters
So, resultant speed of Tarzan, V = √(Vt² + Vr²)
⇒ V = √(2.4² + 5.2²)
⇒ V = √(5.76 + 27.04²)
⇒ V = √32.8 m/s
⇒ V = 5.73 m/s
Thus, rate of swimming = Width / V
⇒ rate of swimming = 1660 / 5.73 s
⇒ rate of swimming = 289.70 s
or, rate of swimming = 4.83 minutes
Thus, Tarzan’s final rate of swimming is 4.83 minutes.

When Nick checked his work it did not match the standard form function. Analyze Nick’s work. What was his mistake?
In step 1, he did not put the function in standard form correctly.
In step 2, he should have also factored –7 from the constant term, 17.
In step 3, he did not subtract –7(9) to keep the function equivalent.
In step 4, he did not write the perfect square trinomial correctly as a binomial squared.
In step 3, he did not subtract –7(9) to keep the function equivalent. Therefore, the correct option is option C among all the given options.
What is mathematical function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a predictor variables (the dependent variable).
In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences. German mathematician Paul Dirichlet initially offered the standard concept of function in 1837. When Nick checked his work it did not match the standard form function. In step 3, he did not subtract –7(9) to keep the function equivalent.
Therefore, the correct option is option C.

Nick wrote the function p(x) = 17 + 42x – 7x2 in vertex form. His work is below.
p(x) = –7x2 + 42x + 17
p(x) = –7(x2 – 6x) + 17

p(x) = –7(x2 – 6x + 9) + 17
p(x) = –7(x – 3)2 + 17
When Nick checked his work it did not match the standard form function. Analyze Nick’s work. What was his mistake?
In step 1, he did not put the function in standard form correctly.
In step 2, he should have also factored –7 from the constant term, 17.
In step 3, he did not subtract –7(9) to keep the function equivalent.
In step 4, he did not write the perfect square trinomial correctly as a binomial squared.
Nick made mistakes in converting to standard form, factoring constants correctly, maintaining equivalence, and writing perfect square trinomials. Correcting these steps will yield an accurate transformation of the equation.
Let's break down the steps Nick likely took and identify where he went wrong in putting the quadratic equation into its standard form.
Step 1: Initially converting the equation to standard form. For the equation x² + 4x + 21 = 0, the equation was already in standard form, so no changes were necessary here. It’s possible that Nick incorrectly adjusted coefficients, which led to errors.Step 2: Factoring out terms. If Nick had an equation like -7x² + 17 = 0, he should have factored out -7 from both the x² term and the constant term, resulting in -7(x² - 17/7) = 0. Missing this step would lead to misrepresentation of the equation.Step 3: Ensuring equivalence. Nick should have subtracted -7(9) correctly to maintain the function's equivalence throughout the transformation.Step 4: Writing the perfect square trinomial correctly. To complete the square, for example, (x + 2)² should be correctly represented as a binomial squared. Not doing so indicates an error in the transformation process.In summary, Nick’s mistakes include incorrect standard form conversion, improper factoring of constant terms, failing to maintain equivalence, and incorrect representation of perfect square trinomials.
