Can someone help me solve this with showing your work and how you got the answer? Whoever does this gets brainiest!

17

Step-by-step explanation:

15 - 35 ÷ 7 ∙ 2 + 3 ∙ 4 =

Follow the correct order of operations.

= 15 - 5 ∙ 2 + 12

= 15 - 10 + 12

= 5 + 12

= 17

the answer is 17

Step-by-step explanation:

We follow a rule called the PEMDAS it stands for parenthese, exponents, multiplicatio, divison, additio, subtraction

(also keep in mind that for the M D A S always do multiplication or division first then additio and subtraction)

Step 1: in this case we do NOT have parenthesis or exponents so we can elimate P and E so we see that 35 is divided by 7= 5

Step2: now our equation is 15-5*2+3*4 now we see that 5 is multiplied to 2=10 and 3 is multiplied to 4=12

step 3: our equation now looks: 15-10+12 (whichever operation comes first do that in this case it’s subtraction so 15-10=5)

step 4: 5+12=17

therfor the final answer is 17

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
