Which answer is an equation in point-slope form for the given point and slope?
Point: (5, 9); Slope: 2
y-5= 2 (2 +9)
y-9=2(x+5)
y+9= 2(2-5)
y-9=2(x – 5)
Answer: y-9=2(x-5)
Step-by-step explanation: The point (5,9) satisfies the equation:
y-9=2(x-5) for (5,9)?
9-9=2(5-5) ?
0 = 0 YES
Slope of 2? Rewrite:
y-9=2(x-5)
y = 2(x-5)+9
The slope is 2 YES

Answer:
c = 9
Step-by-step explanation:
first, simplify 30/2c. which is 15/2c. then cross multiply. 15 x 12 = c x 20.
you get 180 = c x 20. swap sides, c x 20 = 180. divide both sides by 20, then simplify to get 9.

A rectangle has a perimeter of 36 cm. Its width is 4 cm less than its length. Find
the length and width of the rectangle.
Answer:
14
Step-by-step explanation:
Perimeter = 2 x length + 2 x width = 2L + 2w
Width is 4 cm less than the length, so w = L-4
36 = 2L + 2(L-4)
36 = 2L + 2L - 8
36 = 4L - 8
44 = 4L
L = 11
w = 7
2(11) + 2(7) = 22 + 14 = 36
Length is 11, width is 7
Solve F=D+Drt for t.....
Answer:

What is the midpoint of the line segment?
Drag the coordinates to the boxes to correctly match the endpoints and midpoint
Using the midpoint concept, it is found that:
The midpoint of the line segment of endpoints [tex](2, \sqrt{3})[/tex] and [tex](-6, 5\sqrt{3})[/tex] is [tex](-2, 3\sqrt{3})[/tex].The midpoint of the line segment of endpoints [tex]\left(-\frac{5}{3}, \frac{2}{5}\right)[/tex] and [tex]\left(\frac{1}{3}, \frac{3}{2}\right)[/tex] is: [tex]\left(-\frac{2}{3}, \frac{19}{20}\right)[/tex]The midpoint of a line segment is given by the mean of the coordinates of it's endpoints.
For the first segment, which endpoints [tex](2, \sqrt{3})[/tex] and [tex](-6, 5\sqrt{3})[/tex]:
[tex]x_M = \frac{2 - 6}{2} = -2[/tex]
[tex]y_M = \frac{\sqrt{3} + 5\sqrt{3}}{2} = 3\sqrt{2}[/tex]
The midpoint is [tex](-2, 3\sqrt{2})[/tex]
For the second segment, which endpoints [tex]\left(-\frac{5}{3}, \frac{2}{5}\right)[/tex] and [tex]\left(\frac{1}{3}, \frac{3}{2}\right)[/tex]:
[tex]x_M = \frac{-\frac{5}{3} + \frac{1}{3}}{2} = -\frac{4}{6} = -\frac{2}{3}[/tex]
[tex]y_M = \frac{\frac{2}{5} + \frac{3}{2}}{2} = \frac{\frac{4 + 15}{10}}{2} = \frac{19}{20}[/tex]
The midpoint is [tex]\left(-\frac{2}{3}, \frac{19}{20}\right)[/tex]

what divided by 25 = 4.8?
Answer:
120/25 = 4.8
Step-by-step explanation:
To set up the equation you would do this-
[tex]\frac{4.8}{1} =\frac{x}{25} \\[/tex]
Then cross multiply (multiply 4.8 by 25 and x by 1)
[tex]4.8(25) = x(1)\\120 = x[/tex]
Juan graphed a line with a slope of −23 .
How does Juan count the slope from any point on the graph?
From any point on the graph, he counts down 2 then right 3 to end up on the line again.
From any point on the graph, he counts up 2 then right 3 to end up on the line again.
From any point on the graph, he counts down 2 then left 3 to end up on the line again.
Answer:
The answer is: From any point on the graph, he counts down 2 then right 3 to end up on the line again.
Step-by-step explanation:
To count the slope of the graph from any point on the graph; He counts down 2 then right 3 to end up on the line again.
The slope of a linear graph refers to the change behaviour of its dependent variable (usually y-axis) with respect to its Independent variable (usually x-axis).
In essence;
slope, m = (y2-y1)/(x2-x1)
Consequently, From any point on the graph, he counts down 2 then right 3 to end up on the line again.

At a farm the ratio of cows to horses was 9: 2 if there were 72 cows at the farm how many horses were there
Answer:
16 Horses!
Step-by-step explanation:
Since
9 : 2 = 72 : X
Then we know
2/9 = X/72
Multiplying both sides by 72 cancels on the right
72 × (2/9) = (X/72) × 72
72 × (2/9) = X
Then solving for X
X = 72 × (2/9)
X = 16
Therefore
9 : 2 = 72 : 16
what is the measure of F?
pleaseeee
Answer:
D
Step-by-step explanation:
The 3 angles in a triangle sum to 180°
Sum the 3 given angles and equate to 180
2x + 3 + 7x - 5 + 3x + 14 = 180 , collect like terms
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Then
∠ F = 7x - 5 = 7(14) - 5 = 98 - 5 = 93° → D

CAN ANYONE PLZ HELP ME WITH THIS WORKSHEET .. I’ll mark as brainliest
Answer:
Step-by-step explanation:
1)
We know that if [tex]x^2=9[/tex], then [tex]x=\pm \sqrt{9}[/tex], so [tex]\boxed{x=3,-3}[/tex]
2)
We know that if [tex]x^3=8[/tex], then [tex]x=\sqrt[3]{8}[/tex], so [tex]\boxed{x=2}[/tex]
3)
[tex]x^3=\frac{1}{8}[/tex] means that [tex]x=\sqrt[3]{\frac{1}{8}}=\frac{\sqrt[3]{1}}{\sqrt[3]{8}}=\frac{1}{2}[/tex].
So, [tex]\boxed{x=\frac{1}{2}}[/tex].
4)
[tex]x^3=27[/tex] means that [tex]x=\sqrt[3]{27}=\sqrt[3]{3^3}=3[/tex].
So, [tex]\boxed{x=3}[/tex].
5)
[tex]x^2=25[/tex] means that [tex]x=\pm \sqrt{25}=\pm \sqrt{5^2}=\pm 5[/tex].
So, [tex]x=5,-5[/tex].
6)
We know that the side length of the square will be [tex]\sqrt{\frac{9}{16}}=\frac{\sqrt{9}}{\sqrt{16}}=\boxed{\frac{3}{4}}[/tex].
7)
[tex]6x^2=54[/tex] means that [tex]x^2=9[/tex], which means that [tex]\boxed{x=3,-3}[/tex].
8)
[tex]2x^2+25=75[/tex] means that [tex]2x^2=50[/tex], which means that [tex]x^2=25[/tex], which means that [tex]\boxed{x=5,-5}[/tex]

The Lucas numbers are defined by the recursive formula t1 = 2, t2 = 1, tn = tn - 1 + tn - 2, where n âN and n > 2. What are the first 9 Lucas numbers?
The first two are given to you, [tex]t_1=2[/tex] and [tex]t_2=1[/tex]. Use the recursive formula to get the 3rd term; then use the 2nd and 3rd terms to get the 4th; and so on.
Since the n-th Lucas number is the sum of the previous two Lucas numbers, you have
[tex]t_3 = t_2 + t_1 = 1 + 2 = 3[/tex]
[tex]t_4 = t_3 + t_2 = 1 + 3 = 4[/tex]
[tex]t_5 = t_4 + t_3 = 4 + 3 = 7[/tex]
[tex]t_6 = t_5 + t_4 = 7 + 4 = 11[/tex]
[tex]t_7 = t_6 + t_5 = 11 + 7 = 18[/tex]
[tex]t_8 = t_7 + t_6 = 18 + 11 = 29[/tex]
[tex]t_9 = t_8 + t_7 = 29 + 18 = 47[/tex]
