Answer:
Step-by-step explanation:
Let x=smaller number
Then x+5=larger number
Now we are told the following:
1/5(x+x+5)=x-5 multiply each side by 5
x+x+5=5x-25 subtract 5x and also 5 from both sides
x+x+5-5-5x=5x-5x-25-5 collect like terms
-3x=-30 divide both sides by -3
x=10-----------------------smaller number
x+5=10+5=15 ---------larger number

Which equation makes the table true?
f( x) = 2 x + 1
f( x) = x 2 + 1
f( x) = x 2 - 1
f( x) = 2 x - 1
Answer:
f( x) = x ^2 + 1
The equation f( x) = x² + 1 makes the table true.

The given table is
x y
0 1
2 5
5 26
7 50
The table value satisfy with the function f( x) = x² + 1=y
if x=0, then y=f(0)=0² + 1=1
if x=2, then y=f(2)=2² + 1=4+1=5
if x=5, then y=f(5)=5² + 1=25+1=26
if x=7, then y=f(7)=7² + 1=49+1=50
Therefore f(x)=x² + 1 is the equation of table.

Problem 1
Answer: x = 9
----------
Explanation:
For now focus on triangle DEF. We need to find the missing angle D.
D+E+F = 180
D+71+42 = 180
D+113 = 180
D = 180-113
D = 67
In order for DE to be parallel to GH, the alternate interior angles EDF and GHF must be congruent
Let's see what happens when we force them to be equal
angle EDF = angle GHF
67 = 5x+22
67-22 = 5x
45 = 5x
5x = 45
x = 45/5
x = 9

Answers:
Converse: "if it is winter, then it is snowing"
Inverse: "If it is not snowing, then it is not winter"
Contrapositive: "If it is not winter, then it is not snowing"

Explanation:
The original conditional is in the form "If P, then Q". The P and Q are placeholders for logical statements.
We then have the following forms
converse = "if Q, then P" (swap P and Q)inverse = "If not P, then not Q" (negate each)contrapositive = "If not Q, then not P" (do both inverse and converse operations)==========================================

Step-by-step explanation:
=============================================
Explanation:
Angle JEK is composed of two rays EJ and EK
Ray EJ lands on 140 degrees while EK is on 180 degrees
Subtract the two values: 180-140 = 40
So angle JEK is 40 degrees. Since this is less than 90, the angle is acute.

The individual being studied are the characteristics of high definition televisions
Size of television is a continuous variable as the inches of televisions aren't finite and may not necessarily be whole numbers.
Screen type is a Qualitative variable also called categorical as it places different Television sets into distinct category based on the nature of the screen material.
Number of channela is discrete as it defines a finite number stations available. Available stations will always be whole numbers without decimals.

Kailey wrote 8,912,000 in scientific notation as 89.12 times 10 Superscript 5. Which statement best describes Kailey’s work?
Kailey is correct: 89.12 times 10 Superscript 5 equals 8,912,000.
Kailey is not correct: the exponent of ten should be negative.
Kailey is correct: it is written as a decimal number multiplied by a power of ten.
Kailey is not correct: 89.12 times 10 Superscript 5 is not written in scientific notation.
Answer:
kailey is not correct 89.12 times 10 superscript 5 is not written in scientific notation
Step-by-step explanation:
8.912 times 10 superscript 5 is written is scientific notation
The true statement about Kailey's expression is (a) Kailey is not correct: 89.12 * 10 ^5 is not written in scientific notation.
How to determine the true statement?From the question, Kailey's expression can be represented as:
8,912,000 = 89.12 * 10^5 in scientific notation
To check if Kailey's expression is correct, we count the number of zeros in the number up to 8.9
The number of zero is 6.
So, the scientific notation of the number is
8,912,000 = 8.912 * 10^6
This means that Kailey's expression is not correct
Hence, the true statement is (d)

which is the point-slope equation of a line with a slope of 1/2 that contains (-4,7)
Write a linear function f with f(-4) = 2 and f(6) =-3
Answer:
f(x) = - [tex]\frac{1}{2}[/tex] x
Step-by-step explanation:
The standard form for a linear function is
f(x) = ax + b
Using the given values f(- 4) = 2 and f(6) = 3 , then
- 4a + b = 2 → (1)
6a + b = - 3 → (2)
Subtract (2) from (1) term by term to eliminate b
- 10a = 5 ( divide both sides by - 10 )
a = - [tex]\frac{1}{2}[/tex]
Substitute a = - [tex]\frac{1}{2}[/tex] into either of the 2 equations and solve for b
Substituting into (1)
2 + b = 2 ( subtract 2 from both sides )
b = 0
Thus the linear function is
f(x) = - [tex]\frac{1}{2}[/tex] x
The linear function is f(x) = -0.5x
For f(-4) = 2
x₁ = -4, y₁ = 2
For f(6) = -3
x₂ = 6, y₂ = -3
The slope(m) is found using the formula
m = (y₂ - y₁)/(x₂ - x₁)
m = (-3-2)/(6-(-4))
m = -5/10
m = -0.5
Substitute m = -0.5, x₁= -4, and y₁ = 2 into the equation below:
y - y₁ = m(x - x₁)
y - 2 = -0.5(x - (-4))
y - 2 = -0.5(x + 4)
y - 2 = -0.5x - 2
y = -0.5x - 2 + 2
y = -0.5x
Therefore, the linear function is f(x) = -0.5x

7y + 8y can be simplified to 15y?
A. True
B. False
Answer:
A. True
Step-by-step explanation:
Since both 8y and 7y have the same variable, and they are both multiplying with the variable, 8y and 7y can be combined.
If one of the numbers had a different variable or if they were being divided instead then you would not be able to simplify.

Answer:
∠ BAF = 140°
Step-by-step explanation:
Since BD is a tangent to the circle at point B , then
∠ ABD = 90°
The exterior angle of a circle is equal to the sum of the 2 opposite interior angles.
∠ BAF is an exterior angle, thus
∠ BAF = ∠ ABD + ∠ BDA = 90° + 50° = 140°

Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that [tex]45+2k+k=180[/tex]. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have [tex]45+3k=180[/tex]. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides [tex]45-45+3k=180 -45 \\3k=135[/tex] as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.
