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].

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]

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!! :)

Wildlife conservationists are concerned that the deer population might not be constant across the National Forest. The scientists found that there were 144 deer in a 16-square-mile area of the forest. In another part of the forest, conservationists counted 117 deer in a 13-square-mile area. Yet a third conservationist counted 216 deer in a 24-square-mile plot of the forest. Do conservationists need to be worried? a. Why does it matter if the deer population is not constant in a certain area of the National Forest? b. What is the population density of deer per square mile? The unit rate of deer per 1 square mile is _______. Constant of Proportionality: Explain the meaning of the constant of proportionality in this problem: c. Use the unit rate of deer per square mile (or 푦 푥 ) to determine how many deer there are for every 207 square miles. d.

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)
If ABC ≌ DEF, and m∠A = (x + 30)°, m∠C = 45°, and m∠D = 80°, what is the m∠A? A. 15° B. 45° C. 50° D. 80°
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°.

y = -3/2x + 5/2
Explanation-
slope intercept form is y = mx + b
so we have to solve the equation for y
2y = 5 - 3x
y = 5/2 -3/2x
or
y = -3/2x + 5/2

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 ?
