plss answer asap i will give brainliest
Part (a)
Answer: -2-----------
Explanation:
Draw a vertical line through -2 on the x axis. This vertical line will cross the blue parabola at some point P. From point P, draw a horizontal line to the y axis. You should arrive at y = -2. Figure 1, in the attached diagram below, shows this process.
================================================
Part (b)
Answers: x = -3 or x = 1-----------
Explanation:
Draw a horizontal line through y = 1 on the y axis. This is because y = f(x).
This horizontal line crosses the parabola at two places. Drop a vertical line straight down to the x axis to note the x values that make f(x) = 1 true.
You should find the solutions to be x = -3 and x = 1
See figure 2.

Answer:
k = 3
Step-by-step explanation:
Assuming the values in the table are in direct proportion, then
y = kx ← is the equation relating x and y with k the constant of proportion, thus
k = [tex]\frac{y}{x}[/tex]
To find k substitute (28, 84 ) into the equation
k = [tex]\frac{84}{28}[/tex] = 3

Answer:
None of given x = -1²/₇Step-by-step explanation:
-(-10x - 8) = -(4x + 10)
10x + 8 = -4x - 10
-8 -8
10x = -4x - 18
+4x +4x
14x = -18
÷14 ÷14
x = -¹⁸/₁₄ = -⁹/₇ = -1²/₇
I think you meant -(10x-8)=-(4x+10)
Then:
-(10x - 8) = -(4x + 10)
-10x + 8 = -4x - 10
-8 -8
-10x = -4x - 18
+4x +4x
-6x = -18
÷(-6) ÷(-6)

The triangles shown below must be congruent is True statement.
What is Congruency?Two geometric figures are said to be congruent, or to be in the relationship of congruence, if one can be superimposed on the other and they correspond throughout.
As, Two triangles are congruent if their two angles and included sides are equivalent to the other triangle's two angles and included side.
Confirm that the triangles are congruent:
Both of the triangles given are right-angled triangles.
The included side between the angles 45° and 90° in both triangles is 12 units.
This is a necessary condition for the ASA congruence rule.
Thus, the given statement is True statement.

Find the y and x and the given slope of the given line: Line E.
Answer:
change in y: 0
change in x: 5
slope: 0
Step-by-step explanation:
Sub these two points from Line E into the gradient formula (you can search this up on the internet) and you would get 0/5
Points: (1,3) and (6,3)
Rise over run
3-3 over 6-1
0/5 and the answer is 0

Answer:
[tex]33,680 cm^2[/tex]
Step-by-step explanation:
The formula needed for this problem is..
[tex]S.A=2(l*w)+2(l*h)+2(w*h)[/tex].
Given that;
The height of the door= 200cm
The length of the door= 3cm
The width of the door= 80cm
Now, substitute the formula with the information given.
[tex]S.A= 2(3*80)+2(3*200)+2(80*200)[/tex]
[tex]S.A= 2(240)+2(600)+2(16000)[/tex]
[tex]S.A= 480+1200+32000[/tex]
[tex]S.A= 33,680 cm^2[/tex]
Solve for a.
7a + 18 = 102
a =
Answer:
a=12
Step-by-step explanation:
7a+18=102
first, subtract 18 FROM BOTH SIDES!
then you get 7a=84.
next, divide BOTH SIDES by 7
and you get a =12 :)

A use bike costs $75 a new one costs $300. how many times more expensive is a new bike compare with a use bime
Answer:
300-75=225
Step-by-step explanation:
The proportionality constant is k = 4
The cost of the new bike is 4 times the cost of used bike
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportionality constant be represented as k
Now , the cost of used bike A = $ 75
The cost of new bike B = $ 300
The proportionality constant k = cost of new bike B / cost of used bike A
Substituting the values in the equation , we get
The proportionality constant k = 300/75
The proportionality constant k = 4
Therefore , the new bike is 4 times the cost of used bike
Hence , the proportionality constant is 4

Jordan is five years older than twice Amanda's age. Their combined age is 38 years.
What is Jordan's age?
Answer:
27
Step-by-step explanation:
Let a represent Amanda's age. Then Jordan's age is 2a+5, and the combined ages are ...
a +(2a+5) = 38
3a = 33
a = 11
So, Jordan's age is ...
2(11) +5 = 27

1 pts Question 5 3.c. A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 miles. The map needs to be reproduced at a different scale so that it has an area of 6 square inches and can fit in a brochure. At what scale should the map be reproduced so that it fits on the brochure? 1 inch to___ miles
Answer:
The actual area 21600 miles²
Step-by-step explanation:
Lets explain how to solve the problem
- A drawing that shows a real object with accurate sizes reduced or
enlarged by a certain amount called the scale
- Drawing scale is a ratio between the drawing length and the
actual length
- To find the actual dimensions from the drawing dimensions use the
scale drawing
* Lets solve the problem
- A map of a rectangular park has a length of 4 inches and a width
of 6 inches
∴ The drawing dimensions are:
# length = 4 inches
# width = 6 inches
- The scale of the map is 1 inch foe every 30 miles
∴ The scale drawing is 1 : 30
- To find the actual area find the actual dimensions
∵ The scale drawing is 1 : 30
∵ The length = 4 inches and the width = 6 inches
- By using cross multiplication
∴ 1 : 30
4 : actual length
6 : actual width
∴ Actual length = (4 × 30)/1 = 120
∴ Actual length = 120 miles
∴ Actual width = (6 × 30)/1 = 180
∴ Actual Width = 180 miles
∴ The actual dimensions are 120 miles and 180 miles
∵ The area of any rectangle = length × width
∴ The actual area = 120 × 180 = 21600
∴ The actual area 21600 miles²
which property is needed to solve x/5=13
Answer: Multiplication property of equality
This is the idea that if a = b, then a*c = b*c for any real numbers a,b,c
It allows us to multiply both sides by the same number.
In this case, we multiply both sides by 5 to get
x/5 = 13
5*(x/5) = 5*13 ... multiplying both sides by 5
x = 65
