Answer: example, if both sides of the inequality are multiplied by a negative number, say -3, we get (-2) x (-3) < 7 x (-3) 6 < -21 When both sides of the inequality are multiplied by a negative number, the resulting inequality is not true. To make the resulting inequality true, we have to reverse the inequality symbol.
Answer:
Step-by-step explanation:
cos(46°) = 24/x
x = 24/cos(46°)
Answer:
73
Step-by-step explanation:
2×2×7×2=56
2+2=4
56+4+13=73
If he multiplied the first equation by 5, that would give us:
10x + 45y = 205
Now we need to get -45y to eliminate the y-terms, So we divide -45 / 5 and we get -9. So we multiply the 2nd equation by -9.
(I'm assuming the first equation is actually 2x + 9y = 41, and not 2x + 9 = 41)
Answer:
y = -0.2x + 3.8
Step-by-step explanation:
it states it has been 7 weeks. 0.2 x 7 is 1.4. That means they started with 2.4 + 1.4 meters thick of ice sheet, which is 3.8, which is the number they started with. So, b = 3.8 and it says it melts 0.2 so it's a negative, which is -0.2 as slope. So, y = -0.2x + 3.8
