Solve the system of equations by graphing: -1/3x + y=-1, y=4+1/3x

Answers

$-(1)/(3)x$ + y = -1 ⇒ y = $(1)/(3)x$ - 1

To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope $((1)/(3))$ by counting up 1 and to the right 3 of the y-intercept. This gives you a second point of (3. 0). Draw a line through those two coordinates.

Answer: Plot (0, -1) and (3, 0) and draw a line through them.

***************************************************************************************

y = 4 + $(1)/(3)x$ ⇒ y = $(1)/(3)x$ + 4

Same as above. Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).

Answer: Plot (0, 4) and (3, 5) and draw a line through them.

Hat is the solution to the equation 3/3(4c + 16)=2c+9 ?

c =

Answers

if it is $(3)/(3(4c+16))$ =2c+9, go to AAAAAA
if it is ( $(3)/(3)$ )(4c+16)=2c+9, go to BBBBB

AAAAAAAAA
$(3)/(3(4c+16))$ =2c+9
$(1)/(4c+16)$ =2c+9
times 4c+16 to both sides
1=(2c+9)(4c+16)
distribute
1=8c^2+68c+144
minus 1 both sides
0=8c^2+68c+143
use quadratic formula
c= $(-17- √(3) )/(4)$ or $(-17+ √(3) )/(4)$

BBBBBBBBBBBB
(3/3)(4c+16)=2c+9
1(4c+16)=2c+9
4c+16=2c+9
minus 2c both sides
2c+16=9
minus 16 both sides
2c=-7
divide both sides by 2
c=-7/2
c=-3.5

if it is $(3)/(3(4c+16))$ =2c+9,
c= $(-17- √(3) )/(4)$ or $(-17+ √(3) )/(4)$

if it is ( $(3)/(3)$ )(4c+16)=2c+9, c=-3.5

Acutly its really simple Let's solve your equation step-by-step.3/3(4c+16)=2c+9Step 1: Simplify both sides of the equation.3/3(4c+16)=2c+9Simplify: ((3/3)(4c)+(3/3)(16)=2c+9(Distribute)4c+16=2c+9Step 2: Subtract 2c from both sides.4c+16−2c=2c+9−2c2c+16=9Step 3: Subtract 16 from both sides.2c+16−16=9−162c=−7Step 4: Divide both sides by 2.2c/2=−7/2c=−7/2Answer:c=−7/2

There are 20 students in a math class who have brown hair. This represents 80 percent of the students in the class. Which equation can be used to find the total number of students in the math class? mc012-1.jpg mc012-2.jpg mc012-3.jpg mc012-4.jpg

Answers

x=total number of students.
80% of x=20
Therefore, the equaciton can be used to find the total number of students, in the math class is:
(80/100)x=20

We can solve this equation:
(80/100)x=20
x=(20*100)/80=25

Answer: the equation is (80/100)x=20 and its solutions is 25 students.

Answer:

The Answer is 25 students.
