[tex]slope = \frac{2}{ - 7} \\ [/tex]
[tex]slope = - \frac{2}{7} \\ [/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Answer:
[tex]\boxed {\boxed {\sf m= -\frac{2}{7}}}[/tex]
Step-by-step explanation:
The slope of a line can be found using the following formula:
[tex]m=\frac{y_2-y_2}{x_2-x_1}[/tex]
Where (x₁,y₁) and (x₂,y₂) are the points on the line.
We are given the points (12,7) and (5,9). Therefore:
[tex]x_1=12\\y_1=7\\\\x_2=5 \\y_2=9[/tex]
Substitute the values into the formula.
[tex]m=\frac{9-7}{5-12}[/tex]
Solve the numerator.
Subtract 7 from 9 9-7=2[tex]m=\frac{2}{5-12}[/tex]
Solve the denominator.
Subtract 12 from 5 5-12= -7[tex]m=\frac{2}{-7}[/tex]
This fraction cannot be reduced further, so it is the answer.
The slope of the line is -2/7
A new Youth Sports Center is being built in Pagosa Springs. The perimeter of the rectangular playing field is 236 yards. The length of the field is 2 yards less than
double the width. What are the dimensions of the playing field?
The width is yards
The length is yards.
Answer:
Width = 40 yards ; length = 78 yards
Step-by-step explanation:
Recall :
Perimeter of rectangle : 2 (length + Width)
Given that :
Perimeter = 236 yards
Let length = l ; width = w
Length = (2w) - 2
Hence ;
236 = 2[(2w - 2) + w]
236 = 2(2w - 2 + w)
236 = 2(3w - 2)
236 = 6w - 4
236 + 4 = 6w
240 = 6w
w = 240/6
w = 40 yards
Length = 2(40) - 2 = 80 - 2 = 78 yards

Find two integers whose sum is 19 and product is 90
Answer:
Step-by-step explanation:
The two integers are 10 and 9
10 + 9 = 19
10 x 9 = 90
The two numbers are 9 and 10.
What are integers?A number without a decimal or fractional element is known as an integer, which can be both positive and negative, including zero
Let the two integers be x and y.
Given that, the sum of the integers is 19, therefore,
x + y = 19
x = 19 - y
Given that, the product of the integer is 90:
xy = 90
(19-y)y = 90
19y - y² = 90
y² -19y + 90 =0
y² -10y - 9y + 90 = 0
y(y - 10) -9(y - 10) = 0
(y -9)(y - 10) = 0
y = 9 and y = 10
Hence, the two numbers are 9 and 10.

if f(x)=x2+3x+5 what is f(3+h)
Can someone please help me!!
Answer:
13
Step-by-step explanation:
Firstly we would start off by simplifying the equation by doing the order of operations backward (PEMDAS -> SADMEP) and multiply -4 and -3 which would equal a positive 12
Next, we would divide 12 and -6 and get a negative 2
Finally, we would have the equation 1 - 12 + (-2)
We would solve the equation to get -13/(-1)³
This would make the -13 into a positive since any number over one is a whole number. -13 is getting divided by (-1) 3 times so it converts to a positive, then a negative, then back to a positive.

Hello I need help with this, Don Manuel has 600m of fence to build a rectangular-shaped corral. You will take advantage of a very long wall as one of the sides of the pen, that is, on the side of the wall you will not use fence. What should be the dimensions of the pen with maximum area among all those that use 600m of fence?
Answer: If the wall is 300 meters long, the dimensions of the fence with the maximum area will be 300 × 150 = 45000 m²
Step-by-step explanation:
try combinations in a chart
190 × (600-190)/2 = 38950 = 190 × 205 increasing area
200 × (600-200)/2 = 40000 = 200 × 200
220 × (600-220)/2 = 41800 == 220 × 190
240 × (600-240)/2 = 43200 == 240 × 180
260 × (600-260)/2 = 44200 == 260 × 170
280 × (600-280)/2 = 44800 . == 280 × 160
300 × (600-300)/2 = 45000 == 300 × 150 Maximum Area
310 × (600-310)/2 = 44950 . == 310 × 145 decreasing area
320 × (600-320)/2 = 44800 . == 320 × 140

Answer:
y= -1/2 + 2
Step-by-step explanation:
To find m or the slope you need to find 2 locations that the line intercepts a point on the graph. I used (0,2) and (2,1).
Then you find the difference of the x and y coordinates. (x,y)
X-coordinates: 0 and 2. 0 - 2 = -2
Y-coordinates: 2 and 1. 2 - 1 = 1
A slope fraction is the difference of y over the difference of x coordinates. It would be written as 1/-2 or -1/2. m= -1/2
To find the b value, just look at the y-intercept or where the line intercepts the y-axis. Which is at (0,2). So b=2

C LMN > MQP by SAS.
D LMN > MQP by SSS.
5. P is the midpoint of TS and TR=SR= 1.4 inches. What can you conclude about TRP and SRP?
F TRP > SRP by SAS.
G TRP > SRP by SSS.
H TRP > SPR by SAS.
J TRP > SPR by SSS.
4) The correct statement is B: LMN > QMP by SSS. 5) The correct statement is G: TRP > SRP by SSS.
Question 4
The correct answer is B: LMN > QMP by SSS.
In triangle LMN, all three sides are congruent, so it is an equilateral triangle. In triangle QMP, all three sides are also congruent, so it is also an equilateral triangle. Therefore, both triangles are congruent by SSS. This means that LMN and QMP have the same side lengths, and therefore LMN > QMP.
Question 5
The correct answer is G: TRP > SRP by SSS.
Since P is the midpoint of TS, then TP = SP. Also, TR = SR = 1.4 inches. This means that the two triangles TRP and SRP have all three sides congruent, so they are congruent by SSS. Therefore, TRP > SRP.

Persevere with Problems Suppose an online store has an item that costs $50. The item is on sale for 10% off the original price. 10% of $50 = $
Answer:
$5
Step-by-step explanation:
To find 10% of $50 we will use 50*0.10 since 10%=.10
the result of this is 5/ $5
A percentage is a number or ratio that can be expressed as a fraction of 100.
The amount of 10 percent of $50 is $5.
i.e 10% of $50 = $5
What is a percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
We have fractions for different percentages.
50% = 1/2
20% = 1/5
25% = 1/4
10% = 1/10
We have,
Cost of the item = $50
We need to find the 10% of $50.
10% can be written as 1/10.
The value of 10% of $50:
= 10% of $50
= (1/10)x 50
= $5
Thus the amount of 10 percent of $50 is $5.

Find the inverse of the function f(x) = 2x - 4
The correct answer is f^-1(x)=1/2x+2.
1. Substitute y for f(x). ( y=2x+4 )
2. Interchange the variables x and y. ( x=2y-4 )
3. Swap the sides. ( 2y-4=x )
4. Move the constant to the right. ( 2y=x+4 )
5. Divide both sides by 2. ( y=1/2x+2 )
6. Use substitution to substitute f^-1(x) for y.
Thus the inverse is f^-1(x)=1/2x+2
