-5x+13y=-7
5x+4y=24
add the equation to eliminate x:
13y+4y=-7+24
17y=17
solve for y:
17/17y=17/17
y=1
then plug in y into any equation to solve for x:
-5x+13y=-7, y=1
-5x+(13*1)=-7
-5x+13-13=-7-13
-5x=-20
-5/-5x=-20/-5
x=4
the answers are x=4, y=1
You can just multiply the top and the bottom by the same number, and you will get equivalent fractions.
Answer: negative infinity to positive infinity.
Step-by-step explanation:
We are given two sides and their included angle. Using the side-angle-side method we can find the Area of the triangle using the following formula:
Area = 0.5 ab sin(γ)
a = Measure of first side = 3.2 feet
b = Measure of second side = 4.7 feet
γ = Angle between the two sides = 62 degrees
Using the values in the above formula, we get:
Area = 0.5 x ( 3.2) x (4.7) x (sin(62))
Area = 6.64 square feet (rounded to nearest hundredth)
Thus, the Area of the given triangle is 6.64 square feet
Here, f(x) = √x+9
g(x) = 8x - 13
So, for f(g(x)), just put the value of function g(x) in the function f(x)
It would be: f(g(x)) = √8x - 13 + 9
f(g(x)) = √8x - 4
Now, Take √4 as a common factor:
f(g(x)) = √4(√2x - 1)
f(g(x)) = 2(√2x - 1)
In short, Your Answer would be: f(g(x)) = 2(√2x - 1)
Hope this helps!
