Passes through (-4, 2 ) and parallel to y = 1/2x + 5
lord [1]

Answer:

y = 1/2x + 4

Step-by-step explanation:

Lines that are parallel have the same gradient....in which its 1/2

Equation of the line that is parallel to y = 1/2x + 5 and passes through (-4,2)

(y - 2) = 1/2(x + 4)

2(y - 2) = x + 4

; 2y - 4 = x + 4

Equation of the line,

y = 1/2x + 4

How many ML of a 35% acid mixture and a 95% acid mixture should be mixed to get 120 ML of a 40% acid mixture?
Anon25 [30]

<u>ANSWER: </u>

110ML of 35% acid solution must be mixed with 10ML of 95% solution to obtain 120ML of 40% solution.

<u>SOLUTION:   </u>

First, set up table. fill in the unknowns with variables x and y.  The table is attached below.

From the table shown below, we can easily set up the two equations.  

Sum of values of two acids = Value of mixture  

0.35x + 0.95y = 48  

For convenience, we will multiply the entire equation by 100,

35 x + 95y = 4800     ------ (1)  

Now, Sum of amounts of each acid = Amount of mixture  

x + y = 120    --------- (2)

Multiply eqn 2  with 35 for easy calculation and derive the equation into one variable.

35 = 35x + 35y = 4200  

Subtracting equation (2) from (1),  we get

0 + 60y = 600  

Thus, 60y = 600  

y = \frac{600}{60} = 10

Substituting y = 10 in (2),

35x + 35(10) = 4200  

35x + 350 = 4200  

35x = 4200 - 350  

35x = 3850  

x = \frac{3850}{35} = 110

So, we have x = 110 and y = 10

We can conclude that 110ML of 35% acid solution must be mixed with 10ML of 95% solution to obtain 120 ML of 40% solution.

What is the height of the following triangle if the area is 60 square meters? Do not round your answer.
olga nikolaevna [1]

Answer: Height = 8 m

Step-by-step explanation: We have to find h...

We're given two values

A = 60

B = 15

60 is equal to 1/2 x 15

Solve for h:

h = 60 / (1/2 x 15)

h = 60 divided by 7.5

h = 8

I hope this helps!
