Answer: D
Step-by-step explanation:
Given that Svana wants to solve the equation 1/2x - 1.0675 = 3x - 4145.
This equation is a system of equations which can be solved by using simultaneous equation methods.
But if she uses a graphing program to graph the equations y = 1/2x - 1.0675 and y = 3x - 4.145
The solution of 1/2x - 1.0675 = 3x - 4.145. Will be the point of intersection of the two equation.
Trace the point of intersection to the x - axis and also to the y - axis.
The solution to the system of equations is ( 1.231, - 0.452 )
Answer:
E. Step 3
Step-by-step explanation:
Step 2:
2x + 18 = 4x + <u>28 + 2</u>
Step 3:
2x + 18 = 4x + <u>26</u>
She subtracted instead of adding (see bold and underline)
Answer:
the answer is y= x+7
Step-by-step explanation:
the answer is y= x+7 because you have to move the -2x over to where the 14 is and it becomes positive then you divide 2 by 2x and 14 by 2 then you get the answer
Answer:
P = 26 feet
Step-by-step explanation:
The ratios of corresponding sides are in proportion, thus
= 
( cross- multiply )
6P = 156 ( divide both sides by 6 )
P = 26 ← length of shadow of tree
