Write the perimeter of the rectangle as a simplified expression
The simplified expression for the perimeter of the rectangle is 16x - 4. The perimeter of a rectangle is given by the formula: P = 2 * (length + width).In this case, the length of the rectangle is given as 7x + 1, and the width is given as x - 3.
So, the perimeter can be expressed as: P = 2 * (7x + 1 + x - 3)
Now, let's simplify this expression: P = 2 * (8x - 2)
P = 16x - 4
Therefore, the simplified expression for the perimeter of the rectangle is 16x - 4.
A rectangle is a type of quadrilateral with specific properties that distinguish it from other shapes. Here are some key properties of a rectangle:
Opposite Sides are Equal in Length: In a rectangle, the opposite sides are always equal in length. This means that the length of one pair of parallel sides is the same as the length of the other pair.
Opposite Angles are Equal: The opposite angles in a rectangle are equal in measure. This property makes all angles in a rectangle right angles (90 degrees).
Consecutive Angles are Supplementary: Consecutive angles in a rectangle are supplementary, meaning that the sum of any two consecutive angles is 180 degrees. This property is a consequence of the fact that opposite angles are equal, making each pair of consecutive angles form a linear pair.

Find the y-intercept
of the line on the
graph?
9514 1404 393
Answer:
(0, -3)
Step-by-step explanation:
The y-intercept is the point where the graph crosses the (vertical) y-axis. That point is halfway between grid lines marked -2 and -4, so is at the grid line with the value -3. The x-coordinate there is 0, so the y-intercept point is ...
(x, y) = (0, -3)

Since the y-intercept always has an x-coordinate of 0, we sometimes refer to the y-intercept using only the y-value: -3.

Jason surveyed the student athletes at his school as they left the locker rooms for
practice. When selecting from a list of questions, he determined that he could survey
the athletes to determine which sport students in the school most liked to watch.Which
of the following statements is true?
A. Jason is not correct. Since the students are in a small age group, he should go to a baseball game
and survey the spectators there to find the most popular sport to watch.
B. Jason is correct. This population is best for his question.
C. Jason is not correct. Since sports are played during different seasons, he would have to conduct
his survey over the entire school year to get more accurate results.
D. Jason is not correct. Since there are other students in the school that watch sports but do not play them, he should expand his population.

A summer camp has 372 campers who will be going on an outing. Estimate the number of vans needed to accommodate the entire camp if each van can comfortably hold 12 passengers. Then calculate the actual number of vans that will be needed
Answer:
31
Step-by-step explanation:
You divide, 372 divided by 12
the actual number of vans needed is 31 vans to accommodate the entire camp. To estimate the number of vans needed to accommodate the entire camp, we can use the concept of rounding up to the nearest whole number.
The number of vans required will be the total number of campers divided by the capacity of each van (12 passengers), rounded up to the nearest whole number.
Estimate:
Number of vans needed =[tex]\(\frac{372}{12}\)[/tex](rounded up to the nearest whole number)
[tex]\(\frac{372}{12} \approx 31\)[/tex]
So, the estimate suggests that around 31 vans will be needed to accommodate the entire camp.
To calculate the actual number of vans needed, we can use the exact division without rounding up.
Actual number:
Number of vans needed = [tex]\(\frac{372}{12} = 31\)[/tex] vans
Thus, the actual number of vans needed is 31 vans to accommodate the entire camp.

Answer:
angle f = 147 degree and angle e = 33degree
Step-by-step explanation:
here,
angle d= 147 degree
angle f = ?
angle e= ?
we know that,
angle d= angle f (Being alternate angle always be equal.)
or, 147 degree = angle f
Hence, angle f is 147 degree.
And,
angle d sum angle e= 180 degree(being cointerior angle)
or, 147 degree add angle e=180 degree
or, angle e= (180-147) degree
or, angle e= 33 degree
Hence, angle e is 33 degree.
so, angle f=147 degree
angle e= 33 degree
ANS
angle e= 33 degree
Answer:
angle f=147 degrees (alternate angles)
angle e= 33 degrees
Step-by-step explanation:
angle d =147 degrees
angle f=147 degrees (alternate angles)
angle e +angle d=180 (allied angles)
e+ 147 =180
e =180-147
e = 33 degrees

Given H = f(t) where H is the height in meters of an object and t is the time in seconds since it was launched, which of the following is the best interpretation of f(8) = 12?
Answer:
Recall that the height of the object, in meters, is a function of elapsed time, in seconds. Thus what [tex]f(8)=12[/tex] means is that the object is at a height of 8 meters when 12 seconds have passed since its launch.
Best interpretation of the given f(8) = 12 is 8 seconds after the object is launched it is at a height of 12meters.
What is interpretation?
" Interpretation is defined as the explanation of something in your own words or as per your understanding."
According to the question,
Given,
H = f(t)
H represents the height in meters of an object
t represents the time in seconds
Interpretation of the given situation,
f(8) = 12
time = 8seconds
height of the object = 12meters
Hence, interpretation of the given situation is 8 seconds after the object is launched it is at a height of 12meters.

Answer: D
Step-by-step explanation:
m = - 7/4
Point (4, -2)
y - - 2= -7/4(x-4)
y + 2 = - 7/4x + 7
y = - 7/4x +7-2
y = - 7/4 x + 5
The equation of the line that is parallel to the given line is option (D) [tex]y=-\frac{7}{4}x+5[/tex] is the correct answer.
What is equation of a line?The equation of a line means an equation in x and y whose solution set is a line in the (x,y) plane. The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables, and c is the constant term.
For the given situation,
The line is [tex]y=-\frac{7}{4} x-2[/tex] ------ (1)
The general equation of line in slope intercept form is
[tex]y = mx + c[/tex] ------ (2)
On comparing the equation 1 and 2, we get the slope as
⇒ [tex]m=-\frac{7}{4}[/tex] and
When two lines are parallel, then the slope of the parallel line is equal to the slope of the given line.
So, the slope of the parallel line is [tex]m = -\frac{7}{4}[/tex]
Thus the equation of the parallel line passing through the point (x1,y1) is (4,-2) as,
⇒ [tex]y-y1=m(x-x1)[/tex]
⇒ [tex]y-(-2)=-\frac{7}{4} (x-4)[/tex]
⇒ [tex]y+2=-\frac{7}{4} (x-4)[/tex]
⇒ [tex]y=-\frac{7}{4}x+\frac{7}{4} (4)-2[/tex]
⇒ [tex]y=-\frac{7}{4}x+7-2[/tex]
⇒ [tex]y=-\frac{7}{4}x+5[/tex]
Hence we can conclude that the equation of the line that is parallel to the given line is option (D) [tex]y=-\frac{7}{4}x+5[/tex] is the correct answer.
