The answer is 8. This is because when you substitute 8 with “a” you then solve the problem to see if it is equal to the answer. -4+8=4... -4+4=0 so that is wrong and -4+O=-4 which is also incorrect.
Answer:
x=5,y=3
Step-by-step explanation:
the first step is to decide whether you want to substitute y and find x, or substitute x and find y.
(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).
for example, let's substitute y into the first equation:
x=17-4*(x-2)
so now,we will organize the equation:
x+4x=17+8
5x=25/(÷5)
x=5
now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:
y=5-2
y=3
Use the distributive property.
4(4a + 5) = 4 * 4a + 4 * 5 = 16a + 20
Answer: 16a + 20
Answer:
The answer would be B.
Step-by-step explanation:
(-2,2)(0,0)(2,2) represents a nonlinear function.
Answer:
The ratios are both identical (3/5 and 3/5).
Step-by-step explanation:
sin x° is equivalent to O/H, or the opposite/hypotenuse sides of the triangle. Therefore:
sin x° = 3/5.
cos y° is equivalent to A/H, or the adjacent/hypotenuse sides of the triangle.
cos y° = 3/5.
The ratios are identical.
