Answer:
slope of HI is -2
Step-by-step explanation:
so the line looks straight to me so just solve for the slope of D(8,32) E(12,24) which you solve with the equation y2 - y1/x2 - x1
so... 24 - 32 = -8 and 12 - 8 = 4
-8/4 = -2
I hope I helped you ;)
Answer:
0.0625
Step-by-step explanation:
11^-x = 1/(11^x). if that equals four, 11^x = 0.25. 0.25^2 = (11^x)^2 = 11^2x. 0.25^2 = 0.0625. Hope this helps.
77 degrees is the third angle
Answer:
Small boxes contain 60 paperclips and large boxes contain 175 paperclips.
Step-by-step explanation:
1. Set up two simultaneous equations:
Use s for small boxes and l for large boxes. (You could use any letters)
4s + 5l= 1115
3s + 2l= 530
2. Number the equations:
4s + 5l= 1115 (1)
3s + 2l= 530 (2)
3. Multiply both equations to get the same number of ls (for different questions the letters might be different):
<u>(1) x 2:</u>
8s + 10l= 2230 (3)
<u>(2) x 5:</u>
15s + 10l= 2650 (4)
4. Subtract one from the other to get rid of the ls:
<u>(4) - (3)</u>
8s + 10l= 2230
- 15s + 10l= 2650
7s =420
5. Solve for s:
s= 420/7= 60
6. Substitute the s value into one of the original equations to find l:
4 x 60 + 5l= 1115
240 + 5l= 1115
5l= 1115 - 240
5l= 875
l= 875/5= 175
Its simple. You collect like terms and put them on one side of the equation
