Write the square of (2x+1/x)
Answer:
((2 x^2 + 1)^2)/(x^2)
Step-by-step explanation:
Simplify the following:
(2 x + 1/x)^2
Hint: | Put the fractions in 2 x + 1/x over a common denominator.
Put each term in 2 x + 1/x over the common denominator x: 2 x + 1/x = (2 x^2)/x + 1/x:
((2 x^2)/x + 1/x)^2
Hint: | Combine (2 x^2)/x + 1/x into a single fraction.
(2 x^2)/x + 1/x = (2 x^2 + 1)/x:
((2 x^2 + 1)/x)^2
Hint: | Distribute exponents over quotients in ((2 x^2 + 1)/x)^2.
Multiply each exponent in (2 x^2 + 1)/x by 2:
Answer: ((2 x^2 + 1)^2)/(x^2)

A student has started a lawn care business. He charges $15 per hour to mow lawns and $20 per hour for gardening. Because he is still in school, he is only allowed to work for at most 20 hours per week. His goal is to make at least $300 per week.
a. create a system of equations or inequalities that models the situation. define the variables you use.
b. the graph shows one of the relevant equations in this situation. Draw the graph of the other relevant equation.
c. show all the points that represent the number of hours the student can work at each job and meet his goal.
Answer:

Answer:
m<QRS=48°
m<RSQ=69°
m<RQS=63°
Step-by-step explanation:
Since we know that the measures of the angles of any triangle is 180°, we can form this equation: 7a-1+10a-1+9a=180°
Then, we can use simple algebra to solve for a and plug in that value into the equations that the degrees represent to get our angle measures.
7a-1+10a-1+9a=180°
26a-2=180°
26a=182°
a=7
Now, plug in that value of a and you have your anlage measures!! Hope this helps!! :)

Answer:
I think its 80 not sure
Step-by-step explanation:
The measure of ∠A will be 50°.
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Δ ABC ≅ Δ DEF
And, m ∠A = (x + 30)°, m ∠C = 45°, and m ∠D = 80°
Now,
Since, Δ ABC ≅ Δ DEF
Hence, m ∠A = m ∠D
Substitute all the values, we get;
m ∠A = m ∠D
x + 30 = 80
Subtract 30 both side, we get;
x = 80 - 30
x = 50°
Thus, The measure of ∠A will be 50°.

Translate the sentence into an inequality..
The quotient of y and 7 is at least 18.
Answer: [tex]\frac{y}{7} \geq 18[/tex]
Step-by-step explanation:
Key things to remember:
- quotient signals dividing
- at least means greater than or equal to, so we use the greater than or equal to sign
Applying this to the problem, we can translate into a simpler sentence:
y divided by 7 is greater than or equal to 18 --> which leads us to the inequality above

HELP ASAP!right answer I’ll give you a crown
Answer:
[tex]y=-\frac{3}{2}x+1[/tex]
Step-by-step explanation:
Slope-intercept form means
[tex]y=mx+c[/tex]
where m is given its the slope which is [tex]-\frac{3}{2}[/tex] and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,
[tex]y=mx+c[/tex]
[tex]-5 = -\frac{3}{2}(4)+c[/tex]
[tex]-5=-6+c[/tex]
[tex]c=1[/tex]
now we know the value of slope which is given [tex]-\frac{3}{2}[/tex] and we found the value of which is 1 so we put these values into our original slope-intercept form equation
[tex]y=mx+c\\\\y=-\frac{3}{2}x+1[/tex]

The length of the park has been cut off in the question but if it is one mile, like I think it is, then this is the answer.
A = 2/3
A = L x W
2/3 = 1 X ?
? = 2/3
Answer:
width = 2/3 mile
Step-by-step explanation:
area = L * W
where area = 2/3 mile²
length = 1 mile
width = ?
2/3 = 1 (W)
2 = 3W
W = 2/3 mile
therefore the width = 2/3 mile
length = 1 mile

what’s the slope of (9,3) and (2,11)
Answer:
slope = - [tex]\frac{8}{7}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, 3) and (x₂, y₂ ) = (2, 11)
m = [tex]\frac{11-3}{2-9}[/tex] = [tex]\frac{8}{-7}[/tex] = - [tex]\frac{8}{7}[/tex]
Answer:
[tex]\boxed {m = -\frac{8}{7}}[/tex]
Step-by-step explanation:
Use the Slope Formula to help you determine the slope of two given points:
[tex]m =\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Apply the two given points onto the formula:
First point: [tex](9, 3)[/tex]
Second point: [tex](2, 11)[/tex]
[tex]m =\frac{11 - 3}{2 - 9}[/tex]
-Solve for the slope:
[tex]m =\frac{11 - 3}{2 - 9}[/tex]
[tex]m =\frac{8}{-7}[/tex]
[tex]\boxed {m = -\frac{8}{7}}[/tex]
Therefore, the slope is [tex]-\frac{8}{7}[/tex].
