Answer: AC
1) Create was we already know in the equation. 16=-7(-3)+b. (This is using the initial equation of y=mx+b.)
2) Simplify and solve for b: 16=21+b = -5=b
3) Replug your be value into your equation: y=-7x-5.
Answer
y=-7x-5
Words: y equals negative seven x, minus five.
Answer:
3 inches
Step-by-step explanation:
We can use proportions to solve. Put the map on top and the real life size on bottom.
1 inch x inches
------------- = -------------
4 ft 12 ft
Using cross products
1 * 12 = 4 * x
Divide each side by 4
12/4 = 4x/4
3 =x
3 inches
The smallest polygon has three line segments, it is triangle.
An absolute value inequality to find the range of SAT mathematics test scores within one standard deviation of the mean is; |x – 515| ≤ 114
<h3>How to Write Inequalities?</h3>
A) We are told that;
Mean score = 515
Standard deviation = 114
We are now given that people within one deviation of the mean have SAT math scores that are no more than 114 points higher or 114 points lower than the mean. Thus, the absolute value inequality is;
|x – 515| ≤ 114
B) The range of scores to within ±2 standard deviations of the mean is;
Range = 515 ± 2(114)
Range = 287 to 743
