Answer: 4°F
Step-by-step explanation:
From the question, we are informed that temperature at 5:30 a.m was –4°F and that eight hours later, at 2:30 p.m, the temperature is the opposite of –4°F.
The temperature at 2:30 will be 4°F since the opposite of -4 is +4. Also since there's an interval of 8 hours, it's likely that the temperature increased by 1° for every hour. In 8 hours, it'll have increased by 8°, therefore the temperature will then be:
= -4 + 8
= 4°F

Subtract 4x2 – 7x +6 from 2x2 – 5x – 4. Express as a trinomial
Answer: -2x²+2x-10
Step-by-step explanation:
Rephrase the expression
Subtract 4x²-7x+6 from 2x²-5x-4
(2x²-5x-4)-(4x²-7x+6)
Expand parenthesis
2x²-5x-4-4x²+7x-6
Put like terms together
(2x²-4x²)+(7x-5x)-(4+6)
Combine like terms
-2x²+2x-10

Sally is 4 years older than Brody. Evelyn is 3 times older than Brody. If Brody's age is represented by x, create an expression that represents the total age of all three people.
A.4x+4
B. 5x
C.5x+4
D.7x
Answer:
Its C. 5x +4
Step-by-step explanation:
The expression that represents the total age of all three people is f(x) = 5x + 4.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Sally who is 4 years older than Brody. Evelyn is 3 times older than Brody.
Assume that Brody's age is represented by [x]. Then, the age of Evelyn will be (3x) and the age of Sally would be (x + 4). The expression that represents the total age of all three people is -
f(x) = x + (x + 4) + 3x = 5x + 4
f(x) = 5x + 4
Therefore, the expression that represents the total age of all three people is f(x) = 5x + 4.

The segments in each figure are tangent to the circle at the points shown.
Find each length.
9514 1404 393
Answer:
RS = RT = 2
Step-by-step explanation:
The two tangents from a point are the same length.
RS = RT
y = y^2/2
y^2/2 -y = 0
y(y/2 -1) = 0 . . . . factor out y
Values of y that make these factors zero are ...
y = 0 . . . . . . . . true if points R, S, T are coincident on the circle
y/2 -1 = 0 ⇒ y = 2
Then the segment lengths are ...
RS = RT = 2

GOOD AT MATH!! PLEASE HELPPP
Answer:
B. 5
Step-by-step explanation:
Use the pythagorean theorem to solve: [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex].
[tex]a^{2}[/tex]+[tex]12^{2}[/tex]=[tex]13^{2}[/tex]
[tex]a^{2}[/tex]+144=169
Subtract 144 from 169.
[tex]a^{2}[/tex]-144=169-144
[tex]a^{2}[/tex]=25
Square root to get a.
[tex]\sqrt{a}[/tex]=[tex]\sqrt{25}[/tex]
a= 5
Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?
Answer:
20%
Step-by-step explanation:
Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?
The Percentage of the down payment is given as:
Down payment/Cost of the house × 100
Down payment = $25,000
Cost of the house = $125,000
$25,000/$125,000 × 100
= 20%
The percentage is 20%

Two supplementary angles that are 4x and 5x what is the value of x
Answer:
x = 20
Step-by-step explanation:
4x + 5x = 9x
9x = 180 (supplementary angles add up to 180 degrees)
Divide 180/9 = 20
Answer:
x = 20.
Step-by-step explanation:
Supplementary angles sum to 180, so:
4x + 5x = 180
9x = 180
x = 20.
