Answer:


Step-by-step explanation:

Problem A

Basically all you have to do is put in 0 for x to give the y intercept and

0 in for y to give the x intercept. Here we go

x intercept

y =0

0 = (1/4)x -2     Add 2

2 = (1/4)x          Multiply both sides by 4

2*4 = x              Combine and switch

x = 8

===============

x = 0

y = (1/4)*0  - 2

y = -2

Intercept points

x_intercept: (8,0)

y_intercept: (0, - 2)

Problem 2

Essentially you make up the table by using random numbers meaning any number for x and solve for y.

x = -3

y = (-1/-3)(-3) + 1

y = -3/-3 + 1

y = 1 + 1

y = 2

--------------

y = 6

y = (-1/3)*6 + 1

y = -6/3 + 1

y = - 2 + 1

y = - 1

----------------

two other points are

(0,1) and

(-6,3)

To create the graph go to Desmos.

The red graph is y = (1/4)x - 2 The two intercepts are marked.

The blue graph is y = (-1/3)x + 1

The 4 points from the table  are on the blue line. The table is on your left.

If you see a mistake let me know. This is the noisiest place I've ever been in.

The answer is D. To solve 3/5 ÷ 4/7 you would change it to 3/5 × 7/4.

What is the solution to the equation 2/3a-1/6=1/3
Vsevolod [243]

Answer:

a = \frac{3}{4}

Step-by-step explanation:

\frac{2a}{3} -\frac{1}{6} =\frac{1}{3}

\frac{4a}{6}-\frac{1}{6}  =\frac{2}{6}

(now you can multiply the whole equation by 6 to remove the fractions

4a - 1 = 2

4a = 2+1

4a = 3

a = \frac{3}{4}

Arrange the steps to solve the equation square root x+3 - square root 2x-1=-2
stiv31 [10]

Answer:x=31.4919

Step-by-step explanation:

Step1:isolate a square root on the left hand side√x+3=√2x-1-2

Step2:eliminate the radicals on the left hand side

Raise both sides to the second power

√x+3)^2=(√2x-1-2)^2

After squaring

x+3=2x-1+4-4-4√2x-1

Step3:get the remaining radicals by itself

x+3=2x-1+4-4√2x-1

Isolate radical on the left hand side

4√2x-1=-x-3+2x-1+4

4√2x-1=x

Step4:eliminate the radicals on the left hand side

Raise both side to the second power

(4√2x-1)^2=x^2

After squaring

32x-16=x^2

Step 5:solve the quadratic equation

x^2-32x-16

This equation has two real roots

x1=32+√960/2=31.4919

x2=32-√960/2=0.5081

Step6:check that the first solution is correct

Put in 31.4919 for x

√31.4919+3=√2•31.4919-1-2

√34.492=5.873

x=31.4919

Step7:check that the second solution is correct

√x+3=√2x-1-2

Put in 0.5081 for x

√0.5081+3=√2•0.5081-1-2

√3.508=-1.873

1.873#-1.873

One solution was found

x=31.4919
