Answer:
C.) -7x - 5y = -48
Step-by-step explanation:
slope AB = (y2 - y1)/(x2-x1)
= {4-(-1)}/{4-(-3)} = 4+1/4+3 = 5/7
slope of BC = -1 ÷ 5/7 = -1 × 7/5 = -7/5
taking -7x - 5y = -48
-5y = 7x -48
y = 7x/-5 - 48
y = -7/5x -48

Which statement about the graph of this function is true?
Answer:B
Step-by-step explanation:
The exponential curve passes through the point (0, 70). Then the correct option is B.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
The table addresses a few focuses on the diagram of the outstanding capability that models the radioactive rot of an example of xenon-135.
At x = 4.6, the value of 'y' will be 49.5.
[tex]\rm 49.5 = ab^{4.6} \ \ \ \ \ \ \ ...1\\[/tex]
At x = 9.2, the value of 'y' will be 35.
[tex]\rm 35= ab^{9.2} \ \ \ \ \ \ \ ...2[/tex]
From equations 1 and 2, then we have
[tex]\rm \dfrac{b^{9.2}}{b^{4.6}} = \dfrac{35}{49.5}\\\\b^{4.6} = 0.707\\\\b = 0.927\\[/tex]
Then the value of 'a' will be
[tex]\rm 49.5 = a (0.927)^{4.6}\\\\a = 70[/tex]
Then the equation is given as,
y = 70 · (0.927)ˣ
The graph is given below.
The exponential curve passes through the point (0, 70). Then the correct option is B.

what is the answer to 2(3x-5) = 4x+2? Well not the answer but like the steps to solving it
Answer:
x=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(3x−5)=4x+2
(2)(3x)+(2)(−5)=4x+2(Distribute)
6x+−10=4x+2
6x−10=4x+2
Step 2: Subtract 4x from both sides.
6x−10−4x=4x+2−4x
2x−10=2
Step 3: Add 10 to both sides.
2x−10+10=2+10
2x=12
Step 4: Divide both sides by 2.
2x=12
x=6

Answer:
A: Any positive value
Step-by-step explanation:
Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.
Answer:
A: Any Postive value or B: No Solution
Step-by-step explanation:
Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.

The value of a car is $15,000 and depreciates at a rate of 8% per year. What is the
exponential equation?
Sorry for tje late answer but it is 150 * 0.08^x
The exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].
What is depreciation?Depreciation is the rate by which the value of an object reduces with respect to time. it is given by the formula,
[tex]A = P(1-\dfrac{r}{100})^t[/tex]
where A is the value of object after t period of time, P is the principal amount, r is the rate of depreciation, and t is the time period.
We know the formula of the depreciation, Also, the initial value of the car is $15,000, and the rate of depreciation r that is 8% per year. Therefore, the function of the depreciation of the car can be written as,
[tex]A = P(1-\dfrac{r}{100})^t\\\\A = 15000(1-\dfrac{8}{100})^t\\\\A = 15000(1.08)^t[/tex]
Hence, the exponential equation that represents the value of the car is [tex]A = 15000(1.08)^t[/tex].

Find the distance between the two points in simplest radical form. Pleasee answer correctly !!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
[tex]\boxed{\textsf{ The distance between the two points is \textbf{12.164 units }.}}[/tex]
Step-by-step explanation:
Two points are given to us and we need to find the distance in simplest radical form. The given two points are (3,9) & (-2,2) . So lets use Distance Formula to find the distance between them .
Distance Formula is :-
[tex]\sf\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}\\\\\sf\implies Distance =\sqrt{ (-2-3)^2+(9-2)^2}\\\\\sf\implies Distance =\sqrt{ -5^2+7^2}\\\\\sf\implies Distance = \sqrt{ 25 + 49} \\\\\sf\implies Distance = \sqrt{ 74} \\\\\sf\implies Distance=\sqrt{37}\times 2\\\\\sf\implies \boxed{\pink{\sf Distance = 12.164 units .}}[/tex]
