Answer:
The slope is: -1/9
Answer:
-1/9
Step-by-step explanation:
You have 2 points, (x1, y1) and (x2, y2). To find slope, do (y2-y1)/(x2-x1)
(10, 7) and (1, 8)
slope is
(8 - 7)/(1 - 10)
= 1/-9
= -1/9

Answer:
ΔGJH ≅ ΔEKF
HL: GH and EF
SAS: FK and JH (or GH and EF)
ASA: ∠JGH and ∠FEK (or ∠EFK and ∠JHG)
ΔGFJ ≅ ΔEKH
SSS: KH and FJ
SAS: ∠KEH and ∠FGJ
Step-by-step explanation:
List whatever angles/sides need to be congruent for the two triangles to be congruent.
Prove ΔGJH ≅ ΔEKF using....
- HL (Hypotenuse + Leg)
We already have two legs that are congruent (EK and GJ), so we just need the hypotenuses (GH and EF) to be equal.
- SAS (Side + Angle + Side)
1 pair of sides (EK and JG) are equal, and m∠EKF = m∠GJH. So we need one more side. You can either use FK and JH or GH and EF.
- ASA (Angle + Side + Angle)
1 pair of angles (∠EKF and ∠GJH) are already given as equal, and 1 pair of sides (EK and GJ) are equal. We just need one more pair of angles. So either ∠JGH and ∠FEK or ∠EFK and ∠JHG.
Prove ΔGFJ ≅ ΔEKH using...
- SSS (Side + Side + Side)
Two pairs of sides (EK + GJ and EH + FG) are equal, so KH and FJ need to be equal.
- SAS (Side + Angle + Side)
FG + EH and KE + GJ are equal. We need to use the angle in between them to use SAS, so ∠KEH and ∠FGJ need to be equal.

Which 01 the following options best describes the zeros of the quadratic function above?
0) Imaginary zeros
() 2 real zeros
1 real zero and 1 Imaginary zero
f 1 real zero
Answer:
Option (1)
Step-by-step explanation:
Vertex form of the quadratic equation is given by,
y = (x - h)² + k
Where (h, k) is the vertex.
From the graph attached,
Vertex of the parabola is (0, 4).
Therefore, equation of the parabola will be,
y = (x - 0)² + 4
y = x² + 4
Function representing the parabola will be,
f(x) = x² + 4
For the zeros of the quadratic function we find the value of x where f(x) = 0.
x² + 4 = 0
x² = -4
x = ±√(-4)
Since, square root of a negative number is not defined, zeros of the function will be imaginary.
Therefore, both the zeros will be imaginary.
It's clear from the graph, there are no x intercepts of the function Or zeros are imaginary.
Option (1) will be the answer.

Answer:
z = 40°
y = 40°
x = 121°
Step-by-step explanation:
121 + 19 = 140

z = 40
y = 40
x = 121
40 + 19 = 59

Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.
Answer:
5 5/8 miles per hour
Step-by-step explanation:
Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.
We are asked to write the unit rate , this means we are to find out how many miles he can run per hour
Hence,
2/3 hour = 3 3/4 miles
1 hour = x
Cross Multiply
2/3 hour × x = 3 3/4 miles × 1 hour
x = 3 3/4 miles × 1 hour/ 2/3 hour
x = 3 3/4 ÷ 2/3
x = 15/4 ÷ 2/3
x = 15/4 × 3/2
x = 45/8
x = 5 5/8 miles per hour
Lacey deposited $4,860 in a new credit union savings account on the first day of the quarter. The principal earns 4% interest compounded quarterly for 6 months.(a) the amount
Answer:
$4956.23 approx
Step-by-step explanation:
Given data
P= $4860
R= 4%
T= 6 months = 0.5 years
Applying the compound interest formula we have
A=P(1+r)^t
Substitute
A=4860(1+0.04)^0.5
A= 4860(1.04)^0.5
A=4860*1.0198
A=4956.228
Hence the balance will be $4956.23 approx

Which of these statements is true for f(x)=(1/10)^x
A. The domain of f(x) is x > 0.
B. The graph contains (1)
C. It is always increasing.
D. The range of f(x) is y
Answer:it’s B trust me
Step-by-step explanation:
Statemen B is true about the given function.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
A. The domain of f(x) is x > 0 is true for the function [tex]f(x) = (1/10)^x[/tex] because any positive real number can be raised to any real power, so the domain of this function is all real numbers greater than zero.
B. The statement "The graph contains (1)" is not clear. If it means whether the point (1, f(1)) lies on the graph, then we can find that [tex]f(1) = (1/10)^1 = 1/10[/tex], so the point (1, 1/10) lies on the graph. Therefore, the statement is true.
C. The function [tex]f(x) = (1/10)^x[/tex] is always decreasing because as x increases, [tex]f(x) = (1/10)^x[/tex] becomes smaller and smaller, approaching zero as x approaches infinity.
D. The range of f(x) is y < 1 because as x increases, [tex](1/10)^x[/tex] becomes smaller and smaller, approaching zero but never equaling one. So, the range of the function is all real numbers less than one, but not including one itself.

Hello I have two questions for my math homework.
The first question is the attachment-
The second questions is- Mr. Candelaria estimates that the drama club sold 400 tickets to the school play. The drama club actually sold 462 tickets. Calculate Mr. Candelaria’s percent error.
TY!!!!
Answer:
Answers are listed :)
Step-by-step explanation:
1. -81/2 or -40.5
Both answers are correct forms I just didn't know if you wanted fraction or decimal form :)
2. Lots of answers for this one but ill give you mine: Mr. Candeleria probably rounded down his estimate number and in most cases like this you should round up.
Hope this helps :)
The solution is
a) The value of the equation is -40.5 or -81/2
b) Percentage error of Mr.Candelaria in estimating the tickets is 13.42 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
a)
Let the equation be represented as A
Now , the value of A is
A = ( 3 4/5 )x - ( 2 1/2 )
On simplifying the equation , we get
A = ( 19/5 )x - ( 5/2 )
when x = -10 , substitute the value of x = -10 , we get
A = ( 19 × -2 ) - 5/2
A = -38 - 5/2
A = -81/2
A = -40.5
Therefore , the value of A is -40.5
B)
The measured value = 400 tickets
The true value = 462 tickets
Now , the percentage error in estimating the tickets by Mr. Candelaria is given by the formula ,
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Substituting the values in the equation , we get
Percentage Error = [ | 400 - 462 | / 462 ] x 100
Percentage Error = [ | -62 | / 462 ] x 100
Percentage Error = 0.134199 x 100
Percentage Error = 13.419 %
Therefore , the percentage error is 13.42 %
Hence , the percentage error of Mr.Candelaria in estimating the tickets is 13.42 %

Ben bought 19 first class stamps at $0.39 each and 8 postcard stamps at $0.24 each. How much money did Ben spend?
Answer:
Ben spent $9.32 on stamps total
Step-by-step explanation:
19x0.39= 7.41 because it says he bought 19 of these and they each cost $0.39 so you just multiply the two
8x0.24= 1.92 because of the same reason for the other it says he bought 8 of these and each costs $0.24 so you just multiply the two which gets you 1.92
next you add together the two totals of the stamps which is 7.41 and 1.92
7.41+1.92= 9.32
A certain translation takes point D(-3,10) to point D'(-12,21).
What is the image of E(17,-9) under this translation?
Answer:
(8, 2)
Step-by-step explanation:
Subtract the two D points.
(-12) - (-3) = -9
21 - 10 = 11
Then, use it to translate.
(17,-9)
(x - 9, y + 11)
= (8, 2)
The image of E(17,-9) under the translation will be (8,2)
Concept:The D and D' points are given First we will subtract D' from D and we will get X pointsTo find translation of of point E we will add X to E pointHow to solve this problem?The steps are as follow:
GivenD(-3,10)
D'(-12,21)
To find X we will subtract D' from DD'-D = (-12+3,21-10)
X(-9,11)
To find translation of E point we will add X points in EE' = (17-9,-9+11)
E' = (8,2)
Therefore the image of E(17,-9) under the translation will be (8,2)
