Answer:

y = -2/3x + 6

Step-by-step explanation:

Kind of hard to explain but...

From 0,0 go up 6, that is where the + 6 comes from in the answer

The -2/3 is because if you go down 2 (aka -2) and right 3 (aka 3) from point 0,6 you land on point 4,4

One number is 4 more than another, and their sum is 60. What is the smaller number?



If x = the larger number and y = the smaller number, then which of the following systems could be used to solve the problem?

x + y = 60 and -x + y = 4
x + y = 60 and x + y = 4
x + y = 60 and x - y = 4
Unlimited Attempts Remain

Answers

Answer:

Step-by-step explanation:

The system is

x+y=60 and x-y=4

If we get the difference between the two equations above we get

x+y-x+y=60-4

Grace drew a triangle. Its sides were 6 mm. 7 mm and 11 mm.
It has one obtuse and two acute angles.
Complete the sentence to describe the triangle Grace drew.

Answers

Answer:

That would be an obtuse-scalene triangle.

Step-by-step explanation:

It is scalene because none of the sides are congruent. This means that none of the angles or sides are the same.

For all the values of x,
f(x)=2x^2 and g(x)=x+1
Solve fg(x)=gf(x)

Answers

Answer:

if f(g(x)) = g(f(x)), then x is equal to zero.

Step-by-step explanation:

given:

f(x) = 2x²

g(x) = x + 1

then:

f(g(x)) = 2(x + 1)²

g(f(x) = 2x² + 1

so if:

f(g(x)) = g(f(x))

then:

2(x + 1)² = 2x² + 1

2(x² + 2x + 1) = 2x² + 1

2x² + 2x + 1 = 2x² + 1

2x = 0

x = 0

Find the area of a regular pentagon with a side of 5cm round to nearest tenth

Answer:

43 cm^2

Step-by-step explanation:

tan 72/2 = 0.7265

h = 3.44

3.44 x 5 x 0.5 = 8.6

8.6 x 5 = 43 cm^2

Write all three forms (slope intercept, point slope and standard) of a line containing the points (4, -11/3) and (1/2, -29/6).

Answers

Answer:

See explanations below

Step-by-step explanation:

Slope intercept form of the equation is expressed as y = mx+b

m is the slope

b is the intercept

Given the coordinates (4, -11/3) and (1/2, -29/6)

Slope m = -29/6-(-11/3)÷(1/2-4)

m = (-29/6+11/3)÷(-7/2)

m = -29+22/6÷(-7/2)

m = -7/6÷(-7/2)

m = -7/6×2/-7

m = 2/6

m = 1/3

Get the intercept b

Substitute m= 1/3 and (4, -11/3) into y = MX+b

-11/3 = 1/3(4)+b

-11/3 = 4/3+b

b= -11/3-4/3

b= -15/3

b =-5

Get the required equation

y = 1/3 x -5 (slope-intercept form)

Point slope form of the equation is expressed as y-y0 = m(x-x0)

Substituting m = 1/3 and the point (4,-11/3)

x0 = 4

y0 = -11/3

y - (-11/3) = 1/3(x-4)

y+11/3 = 1/3(x-4) (point-slope form)

For standard format

Recall that y = 1/3x - 5

Multiply through by 3

3y = 1/3x(3)-5(3)

3y = x-15

3y-x = -15(standard form)
