Answer:
-1
Step-by-step explanation:
1.)Reorder the terms:
7(8 + x) = 49
(8 * 7 + x * 7) = 49
(56 + 7x) = 49
2.)Solving
56 + 7x = 49
3.)Solving for variable 'x'.
4.)Move all terms containing x to the left, all other terms to the right.
5.)Add '-56' to each side of the equation.
56 + -56 + 7x = 49 + -56
6.)Combine like terms: 56 + -56 = 0
0 + 7x = 49 + -56
7x = 49 + -56
7.)Combine like terms: 49 + -56 = -7
7x = -7
8.)Divide each side by '7'.
x = -1
9.)Simplifying
x = -1

If function f is the parent exponential function , what is the equation of transformed function g in terms of function f?
Replace the value of a to complete the equation.
Answer:
This problem is acually really simple.
Step-by-step explanation:
all you have to do is replace the a with a 3. SO It would look like this:
g(x)=3f(x)
hope this helps :)
The equation of the function g(x) is g(x) = 3f(x) or g(x) = 3e^x
How to determine the equation of g(x)?The function f(x) is given as:
f(x)= e^x
The function is stretched by a factor of 3 to get the function g(x)
This means that:
g(x) = 3 * f(x)
Evaluate the product
g(x) = 3f(x)
Hence, the equation of the function g(x) is g(x) = 3f(x) or g(x) = 3e^x

A company sells fruit smoothies in two sizes: 6 ounces and 20 ounces. You know that a 6-ounce bottle contains 96 milligrams of sodium. If the amount of sodium is directly proportional to the fluid ounces of smoothie, how many milligrams of sodium does a 20-ounce bottle contain?
And can yall put an explanation please
Answer:
320 milligrams of sodium
Step-by-step explanation:
Create a proportion where x is the milligrams of sodium a 20 ounce bottle has:
[tex]\frac{96}{6}[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x
1920 = 6x
320 = x
So, a 20 ounce bottle will have 320 milligrams of sodium

Answer:
The area of shaded figure is 30 sq yards .
Step-by-step explanation:
In the graph the figure is consist of :
Many grid square and each square grid is equals one square yards . Two shapes which are parallelogram and triangle .To calculate the area of shaded figure we need to find the area of triangle and parallelogram and combine them to get the area of shaded figure.
Finding the area of triangle:-
Area of triangle = ½ × Base × Height
substitute the values and solve;Area of triangle = ½ × 5 × 4
Area of triangle = ½ × 20 yard²
Hence, the area of triangle is 10 sq yards.
Finding the area of parallelogram :
Here, to calculate the area subtract the area of two small circle from the area of rectangle .
Area of parallelogram = l × b - 2 (( b × h )½)
Substitute the values we get,Area of parallelogram = 4 × 8 - 2 ( 3 × 4 × ½)
Solve it ;Area of parallelogram = 32 - 12.
Substitute 12 from 32 .Area of parallelogram = 20 sq yards.
Hence, Area of parallelogram = 20 sq yards.
Finding the area of shaded figure.Area of figure = Area of parallelogram + Area of triangle.
Area of figure = 20 sq yards + 10 sq yards.
Add 20 sq yards and 30 sq yards.Area of figure = 30 sq yards .
Hence,
The area of shaded figure is 30 sq yards .

Answer:
60
Step-by-step explanation:
The expression Mrs. Clements use to find the area of the tabletop, in square feet is 0.5 * (5 + 9) * 4
How to determine the area of the tabletop?The dimension of the tabletop is:
Parallel sides = 5 feet and 9 feet
Height = 4 feet
The area is then calculated using:
Area = 0.5 * (Sum of parallel sides) * Height
This gives
Area = 0.5 * (5 + 9) * 4
Hence, the expression Mrs. Clements use to find the area of the tabletop, in square feet is 0.5 * (5 + 9) * 4
