You plug in x+1.75 into the second equation to get 4x-2(x+1.75)=4. Once you simplify and solve that problem for x you should get x = 3.75. Plug the x-value that you got back into one of the equations (y=x+1.75) or (4x-2y=4). Either way your y-value should be 5.5.
Your answer would be A. because (x,y) or (3.75,5.5) in this case
Answer:
(4+4) = 8 (1+1) = 2 then 8 x 2 = 16
so your answer is 16
Step-by-step explanation:
you can use PEMDAS to solve equations like this
I hope this helps you
x= -1 f (-1)=(-1)^2+7=1+7=8
g (f (-1))= g (8)
x=8 g (8)= 8-4/8=4/8=1/2
Answer:
x=9
Step-by-step explanation:
-9x + 1 = -80
-9x = -81 substract 1 from both sides
x= 9 divide both sides by -9
Answer:
h=13
P=5
b=12
Step-by-step explanation:
- tanA=<em>p</em><em>÷</em><em>b</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>2</em>
- sin<em>A</em><em>=</em><em>p</em><em>÷</em><em>h</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>3</em>
- <em>c</em><em>o</em><em>s</em><em>A</em><em>=</em><em>b</em><em>÷</em><em>h</em><em>=</em><em>1</em><em>2</em><em>÷</em><em>1</em><em>3</em>
