Answer:
Step-by-step explanation:
y = 5x - 43.....slope is 5
a parallel line will have the same slope
(-6,0)...x = -6 and y = 0
slope(m) = 5
y = mx + b
0 = 5(-6) + b
0 = -30 + b
30 = b
so ur parallel equation is : y = 5x + 30
We have been given that a jeweler has 5 rings, each weighing 12 g, made of an alloy of 20% silver and 80% gold.
Upon melting all 5 rings, the weight of the material will be 12*5=60 grams.
We have been given that the alloy contains 20% silver and 80% gold. Further, let us assume that x grams of silver are added to the melted material so that it has 64% gold and 36% silver.
Therefore, we can set up an equation:
Therefore, we get an equation:
Therefore, 15 grams of silver must be added to the melted material in order to reduce the gold content to 64%.
Answer:
The linear model of her monthly earnings is; Y =1200 +0.03*X. The amount earned is 1350; choice A
Step-by-step explanation:
Let Y denote her monthly earnings and X her total sales. The linear model can thus be formulated as; Y =1200 +0.03*X. We are then to find the value of Y given X =5000. We simply substitute X =5000 into the linear model which yields; Y =1350
