Answer:
Base = 8
Step-by-step explanation:
Area of a triangle can be calculated as:
Area = 0.5 x Base x Height
The values of the area and the height are given in order to find the length.
A= 52 in^2
Height= 13
First we have to find the base or the length. Using the values above we can set up the equation as:
1. 52= (0.5)(13)(b)
2. 52/0.5(13)
3. b=8
Answer: The length of the guitar or the base would be 8 inches.
I hope this helps and for future problems regarding this topic use the formula above!!
Formula: 0.5 x Base x Height
A) y = 2x – 7 and f(x) = 7 – 2xIncorrect. These equations look similar but are not the same. The first has a slope of 2 and a y-intercept of −7. The second function has a slope of −2 and a y-intercept of 7. It slopes in the opposite direction. They do not produce the same graph, so they are not the same function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5. B) 3x = y – 2 and f(x) = 3x – 2Incorrect. These equations represent two different functions. If you rewrite the first equation in terms of y, you’ll find the equation of the function is y = 3x + 2. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5. C) f(x) = 3x2 + 5 and y = 3x2 + 5Correct. The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5. D) None of the aboveIncorrect. Look at the expressions that follow f(x) = and y =. If the expressions are the same, then the equations represent the same exact function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.
I believe the answer is :
15x + 40
If you just distribute
Answer:
(-4,-2)
Step-by-step explanation:
first u should chose a variable to eliminate and i choose Y
y=5/2x+8-y=-1/4x-3
get a common denominator
5/2= 10/4
-1/4=-1/4
the equation i will change a little because we are subtracting
10/4x+8+1/4x+3
11/4x+11
solve for the remaining variable which is X
subtract 11 on both sides
0-11=11/4x+11-11
-11=11/4x
multiply both sides by 4/11
-11 times 4/11= 11/4x times 4/11
x=-4
then substitute the variable in one of the equations and i choose y=5/2x+8
5/2(-4)+8= y
-20/2+8= y
-10+8=y
y=-2
