Answer: Equation of st line is Y= -9X + 141
Step-by-step explanation: Given Y= 24 when X = 13 and Y = 87 when X = 6
Let the equation be Y = mX + C
24 = m*13 +C
and 87 = m* 6 +C
Give m = -9 and C = 141
Equation of st line is Y= -9X + 141
Answer:
3/5
Step-by-step explanation:
Step one:
given data
Amy saved 1/5
her brother 4/5
Required
How much more did her brother save
Step two:
let us subtract Amy's savings from her brother's
4/5-1/5
=4-1/5
=3/5
Answer:
1) A 2) B 3) C 4) C 5) A 6) B
Step-by-step explanation:
1) Slope is calculated by the change in y over the change in x thus (5-3)/(2-(-1)) = 2/3
2) Since there is no change in y, there is no slope.
3) The change in x is given which is 10-2 so the change in y is y2-3. For the slope to be 3/4 y must equal 6. Therefore y2 is 9.
4) Cosine is adjacent over hypotenuse and Tangent is opposite over adjacent. Given 3/5 as A/H you can construct a right triangle with the adjacent as 3 and hypotenuse as 5. The Pythagorean theorem says the adjacent squared plus the opposite squared is equal to the hypotenuse squared.
3^2 + O^2 = 5^2
O=4
Therefore TanP is 4/3
5) Pythagorean theorem again.
Therefore your hypotenuse is equal to 
6) Csc is the inverse of the Sin function. So it becomes 5/4.
