Answer:
x = 10
Step-by-step explanation:
1/10(x + 130) = -2(3 - x)
x + 130 = -20(3-x)
x + 130 = -60 + 20x
x - 20x = -60 - 130
-19x = -190
x = 10

Which equation represents exponential decay?
O A y = 100(31)
O B. y = 1 (3.1)
C. y = 10(0.13)
D. y = 100(1.03)
Answer:
The function y = 10(0.13)ˣ represents exponential decay.
Hence, option C is the correct function.
Step-by-step explanation:
We know that an exponential function is of the form
y = abˣ
where 0 < b < 1
Please note that an exponential function cannot have a base of 0, 1, or a negative value.
Now, if we carefully observe, the function y = 10(0.13)ˣ is the only option correct as
here 0 < b < 1 and a > 0
Therefore, the function y = 10(0.13)ˣ represents exponential decay.
Hence, option C is the correct function.
Which equation represents a line with a slope of -6/5
and a y-intercept of 1?
Answer:
y = -6/5x + 1
Step-by-step explanation:
The equation that represents a line with a slope of -6/5 and a y-intercept of 1 is y = -6/5x + 1
How to determine the equation?The given parameters are:
Slope, m = -6/5y-intercept = 1Let the variable of the equation be x.
A linear equation is represented as:
y = Slope * x + y-intercept
So, we have:
y = -6/5 * x + 1
Evaluate
y = -6/5x + 1
Hence, the equation is y = -6/5x + 1

Answer:
a
Step-by-step explanation:
Consider the triangles to be similar, that is the the one on the left and the outer one. Then the ratios of corresponding sides are equal, that is
[tex]\frac{40}{72}[/tex] = [tex]\frac{15}{d}[/tex] ( cross- multiply )
40d = 1080 ( divide both sides by 40 )
d = 27 ft → a

what is the simplified form of y^2 -y -12/ y^2 +8y+15
Answer:
(y - 4)/(y + 5)Step-by-step explanation:
Simplify by factoring both trinomials:
(y^2 - y - 12)/ (y^2 +8y + 15) = (y - 4)(y + 3) /(y + 5)(y + 3) =(y - 4)/(y + 5)Felix surrounds a 12 in. by 8 in. photo with a frame that is x inches wide. Which quadratic function represents the combined area A of the picture and the frame?
A. A(x) = x^2 + 20x + 96
B. A(x) = x^2 + 40x + 96
C. A(x) = 4x^2 + 20x + 96
D. A(x) = 4x^2 + 40x + 96
Answer:
D: A(x) = 4x² + 40x + 96
Step-by-step explanation:
Dimensions of photo is;
Length; L = 12 inches
Width; W = 8 inches
Now, this picture is surrounded by a frame that is "x" inches wide. Thus, new dimensions are;
L_new = 12 + x + x = 2x + 12
W_new = 8 + x + x = 2x + 8
New area is;
A_new = (2x + 12) × (2x + 8)
A_new = 4x² + 24x + 16x + 96
A_new = 4x² + 40x + 96

what number is halfway between 8.270 and 8.280? The answer is 8.275 hope this helps
Answer:
8.275
Step-by-step explanation:
8.280 - 8.270 = 0.010
0.010/2 = 0.005
8.270 + 0.005 = 8.275
The number halfway between 8.270 and 8.280 is 8.275.
What is Arithmetic?The study and use of numbers, their connections, and mathematical observations are topics covered by the area of mathematics known as arithmetic. The fundamental ideas in number theory, measurement, and calculation are frequently referred to as "arithmetic" (which is derived from the Greek word "arithmos," "number") (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).
As per the given data:
We have to find the number which is halfway between 8.270 and 8.280.
For finding the number, we can calculate the difference between 8.270 and 8.280 and then divide it by two now we can add the obtained number into 8.270 to get the number.
[tex]\frac{8.280 - 8.270}{2}[/tex]
= [tex]\frac{0.010}{2}[/tex]
= [tex]0.005[/tex]
The number halfway between 8.270 and 8.280:
8.270 + 0.005
= 8.275
Hence, the number halfway between 8.270 and 8.280 is 8.275.
