Step-by-step explanation:
Number 1) Don’t get confused with the -10 and 10, we already know that the value is already 20 so that narrows it to 2 choices. Now everytime you move on, it subtracts 10 so its 20:-10
Number 2) This one is pretty easy, we know that he drives about 12,000 miles a year but we don’t know how many years, so that unknown variable would be (x), now the 40,000 miles was already on it so that can’t change, only The years change so therefore the equation could be 12,000x+40,000
Consider the similar triangle below.
ABC is the per-image and PQR is the image.
Answer:
Scale factor: 2
PR = 14
Perimeter = 34
Step-by-step explanation:
Similar Triangles
Similar triangles are those who have their corresponding side lengths proportional, i.e. the ratio of the corresponding sides is equal.
The figure shows similar triangles ABC and PQR. We can also see corresponding sides BC and QR have lengths 6 and 12 respectively.
The scale factor is [tex]\frac{12}{6}=2.[/tex]
The rest of the sides can be calculated by using the per-image triangle ABC side lengths and the new-found scale factor. Thus:
PR = AC*2 = 7*2 = 14
PR = 14
PQ = AB*2 = 4*2 = 8
The perimeter of the triangle PRQ is the sum of its side lengths:
P = 12 + 14 + 8 = 34
Answers:

If a term doesn't have a coefficient , it is considered that the coefficient is 1
[tex]2x+1x-4y[/tex]
Why is it considered that the coefficient is 1?
Remember that any term multiplied by 1 remains the same:
[tex]1.x=x[/tex]
Step 1
The equality can be read in the other way as well , so any term can be written as a product of 1 and itself:
[tex]x=1 . X \\[/tex]
Step 2
Usually, we don't need to write multiplication sign between the coefficient and the variable , so the simpler form is:
[tex]x=1x[/tex]
That is why we can write the term without the coefficient as a term with coefficient 1.

Step-by-step explanation:
A school is organizing a weekend trip to a nature preserve. for each student, there is a $40 charge, which covers food and lodging. there is also a $30 charge per student for the bus. the school must also pay a $20 cleaning fee for the bus. if the total cost of the weekend is $4,220, how many students will be going on the trip?
The number of students going on the trip is 60.
Given that, total cost = $4220
Cost per student= $30+$40=$70
Additional cost = $20
We need to find the number of students.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of students be x.
Cost paid by students = 4220-20 = 4200
Number of students = cost paid by students/cost per student
x = 4200/70
⇒x= 60
Therefore, the number of students going on the trip is 60.

You have $20 to spend at the dollar store for Jake and Julian's birthdays. You want to buy 2 sodas for Jake, 4 candy bars for Julian, and an equal number of balloons b for them both with the rest of your money. Which equation below will determine how many balloons each friend receives?
Answers
2+4+b/2 =20
2+4+b =20
2+4+2b =20
20-4-2 =b
2(2+4+b) =20
Using a system of equations, the equation that determines how many balloons each friend receives is given by:
2 + 4 + 2b = 20.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable s: number of sodas bought.Variable c: number of candy bars bought.Variable b: number of balloons bought.You want to buy 2 sodas for Jake, 4 candy bars for Julian, hence:
s = 2, c = 4.
An equal number of balloons b, hence 2b is added to the equation, as the amount has to be 2, 4, 6, and so on, considering one balloon for each.
The total amount of money is of $20, hence the equation is:
2 + 4 + 2b = 20.

Find the minimum value of the function. [Hint: Let t = x³.] f(x) = 1 + 12x³ + 3x⁶
===========================================
Work Shown:
t = x³
f(x) = 1 + 12x³ + 3x⁶
f(x) = 1 + 12x³ + 3(x³)²
f(t) = 1 + 12t + 3t²
f(t) = 3t² + 12t + 1
f(t) = 3(t² + 4t) + 1
f(t) = 3(t² + 4t + 4 - 4) + 1 .... see note below
f(t) = 3( (t²+4t+4) - 4) + 1
f(t) = 3( (t+2)² - 4) + 1
f(t) = 3(t+2)² - 3*4 + 1
f(t) = 3(t+2)² - 12 + 1
f(t) = 3(t+2)² - 11
The smallest that t² can get is 0. By extension, the smallest (t+2)² can get is also 0, and same goes for 3(t+2)².
So effectively we replace the 3(t+2)² portion with 0 and end up with 3(t+2)²-11 = 0-11 = -11 as the minimum value of f(x)
This is the smallest output possible. Confirmation of such is shown in the graph below.
------------
Note: Recall that (A+B)² = A²+2AB+B². If we use this rule on (t+2)², then we get t²+4t+4. Earlier we simply had t²+4t without the extra +4 at the end. So I added 4 and subtracted 4 to balance things out. This completed the square.

The equation of the line in slope-intercept form is:
[tex]y\:=\:\frac{-10}{7}x-\frac{45}{7}[/tex]Step-by-step explanation:
Given the points
(-8, 5)(-1, -5)Finding the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-8,\:5\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-5\right)[/tex]
[tex]m=\frac{-5-5}{-1-\left(-8\right)}[/tex]
[tex]m=-\frac{10}{7}[/tex]
We know the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept
[tex]5\:=\:\frac{-10}{7}\left(-8\right)+b[/tex]
[tex]\frac{80}{7}+b=5[/tex]
[tex]b=-\frac{45}{7}[/tex]
now substituting m = -10/7 and b = -45/7 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y\:=\:\frac{-10}{7}x+\left(-\frac{45}{7}\right)[/tex]
[tex]y\:=\:\frac{-10}{7}x-\frac{45}{7}[/tex]
Thus, the equation of the line in slope-intercept form is:

Answer:
The archaeologists dis not actually discovered the lost temple
Step-by-step explanation:
For us to be able to determine if the archaeologist actually discovered the lost temple, we need to find the dimension of the temple first.
Area of the temple = LW
Perimeter = 2L + 2W
L is the length
W is the width
If the perimeter is 220m
220 = 2L + 2W
110 = L+W ... 1
If the area is 2100 square meters
A = LW
2100 = LW ... 2
From 1;
L = 110 - W .... 3
Substitute 3 into 2
From 2;
2100 = LW
2100 = (110-W)W
2100 = 110W - W²
- W² + 110W - 2100 = 0
W² - 110W + 2100 = 0
Using the general formula;
W = -(-110)±√(-110)²-4(1)(2100)/2
W = 110±√3700/2
W = 110±60.83/2
W = 110±60.83/2
W = 110+60.83/2 and W = 110-60.83/2
W = 170.83/2 and 49.17/2
W = 85.415m and 24.585m
Substitute the width into the formula to get the length;
LW = 2100
L = 2100/W
L = 2100/85.415
L = 24.59 m
If the width is 24.585m;
L = 2100/24.585
L = 85.42m
Since we have different dimension of the temple, this show shat the archaeologists dis not actually discovered the lost temple

Aidan's average speed on his drive home is 26 2/3 miles per hour
What is Aidan's average speed?
Average speed is the total distance travelled per time. It indicates how fast an object is moving.
Average speed = total distance / total time
The first step is to determine the time it would take Aidan to drive to school :
Time = distance / speed
16 / 40 = 2/5 hours = 2/5 x 60 = 24 minutes
The second step is to determine the time it would take Aidan to drive from school
Time it would take to drive home from school = 60 minutes - 24 minutes = 36 minutes = 36/60 = 3/5 hours
Aidan's average speed to drive home = 16 miles ÷ 3/5
16 x 5/3 = 80 / 3 = 26 2/3 miles per hour

A wall is 22 feet tall. A ladder is leaned against that wall. The top of the ladder touches the top of the wall and the bottom of the ladder rests on the ground 8 feet from the base of wall. What is the length of the ladder?
Answer:
23.41 feet
Step-by-step explanation:
The ladder forms a right angle triangle with the wall
Height of the wall (opposite) = 22 feet
Bottom of the ladder from the wall (adjacent) = 8 feet
What is the length of the ladder?
Length of the ladder (hypotenuse)
Using Pythagoras theorem
Hypotenuse ² = opposite ² + adjacent ²
= 22² + 8²
= 484 + 64
= 548
Hypotenuse ² = 548
Hypotenuse = √548
= 23.41 feet
The length of the ladder is 23.41 feet

The equation of line is given as : y = 3x + 6
According to the question we have been given that the line passes through the points (-1,3) and has gradient 3
We need to find the equation of line. The general form of slope intercept form is
y = mx + c
where, m = slope
c = intercept
When a point and slope is given then the expression for the equation of line is given as:
[tex](y - y_{1})=m(x-x_{1})\\[/tex] (1)
where (x1,y1) are the coordinates which is (-1,3)
m = slope or gradient = 3
