jolli1 [7]

Answer:

Part 1) $x-2y=2$ ----> (2,0) and (0,-1)

Part 2) $-3x+3y=7$ ----> (-7/3,0) and (0,7/3)

Part 3) $7x-y=21$ ----> (3,0) and (0,-21)

Part 4) $3x-5y=-20$ ----> (-20/3,0) and (0,4)

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

The x-intercept is the value of x when the value of y is equal to zero

Part 1) we have

$x-2y=2$

1) Find the x-intercept

For y=0

$x-2(0)=2\\x=2$

the x-intercept is (2,0)

2) Find the y-intercept

For x=0

$0-2y=2\\y=-1$

the y-intercept is (0,-1)

Part 2) we have

$-3x+3y=7$

1) Find the x-intercept

For y=0

$-3x+3(0)=7\\x=-\frac{7}{3}$

the x-intercept is (-7/3,0)

2) Find the y-intercept

For x=0

$-3(0)+3y=7\\y=\frac{7}{3}$

the y-intercept is (0,7/3)

Part 3) we have

$7x-y=21$

1) Find the x-intercept

For y=0

$7x-(0)=21\\x=3$

the x-intercept is (3,0)

2) Find the y-intercept

For x=0

$7(0)-y=21\\y=-21$

the y-intercept is (0,-21)

Part 4) we have

$3x-5y=-20$

1) Find the x-intercept

For y=0

$3x-5(0)=-20\\x=-\frac{20}{3}$

the x-intercept is (-20/3,0)

2) Find the y-intercept

For x=0

$3(0)-5y=-20\\y=4$

the y-intercept is (0,4)

Which ordered pair describes the location of point P?

Reptile [31]

Coordinates are written (x,y). So find P on the graph. Start at the origin, (0,0), and go left 2 units, sp you're right under P. Since you went left, it's negative, x=-2. Then just go up until you get to P, y=3. So you end up with P is at (-2,3). Hope this helps!

Find the equation of a line that is perpendicular to a line whose equation is 6x - y = -1 and passes through the point ( -1, 5 )

Svet_ta [14]

-y=-6x-1
-1(-y=-6x-1)
y=6x+1
5=6(-1)+b
5=-6+b
b=11

Solve the quadratic equation by factoring. 9x^2-16=0

Harman [31]

Answer:

x= +- 4/3

Step-by-step explanation:

(3x+4)(3x-4)=0

make each equation set to 0 and solve

3x+4=0

subtract 4 from both sides

3x=-4

divide both sides by 3

x=-4/3

3x-4=0

add 4 to both sides

3x=4

divide both sides by 3

x=4/3
