Choose the quadratic equation that has a leading coefficient of 1 and solutions 3 and -2.

ss7ja [257]

Answer:

Option D $x^{2} -x-6=0$

Step-by-step explanation:

Verify each quadratic equation

case A) we have

$x^{2} +x+6=0$

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

$(3)^{2} +(3)+6=0$

$18=0$ ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case B) we have

$x^{2} -x-5=0$

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

$(3)^{2} -(3)-5=0$

$1=0$ ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case C) we have

$x^{2} +x+5=0$

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

$(3)^{2} +(3)+5=0$

$17=0$ ----> is not true

therefore

x=3 is not a solution of the quadratic equation

case D) we have

$x^{2} -x-6=0$

This quadratic equation has a leading coefficient of 1

Substitute the value of x=3 and x=-2 in the equation

For x=3

$(3)^{2} -(3)-6=0$

$0=0$ ----> is true

therefore

x=3 is a solution of the quadratic equation

For x=-2

$(-2)^{2} -(-2)-6=0$

$4+2-6=0$

$0=0$ ----> is true

therefore

x=-2 is a solution of the quadratic equation

What equation in slope-intercept form represents the line that passes

4vir4ik [10]

Answer:

2y = x - 7

Step-by-step explanation:

The general equation of the line is;

y = mx + b

where m is the slope and b is the y-intercept

To get the slope, we use the slope formula

m = (y2-y1)/(x2-x1)

(x1, y1) = (3,-2)

(x2,y2) = (1,-3)

m = (-3+2)/(1-3) = -1/-2 = 1/2

So we have the equation as;

y = x/2 + b

Multiply through by 2

2y = x + 2b

To get the y-intercept value, we substitute any of the points

Let us use the first point

While 3 will go for x , -2 will go for y; thus we have;

2(-2) = 3 + 2b

-4 = 3 + 2b

2b = -4-3

2b = -7

b = -7/2

So the equation is;

2y = x -7

3/8 of a scholarship fund was 1500 find the full amount of the scholarship fund

N76 [4]

Answer:

The full scholarship fund will be 4000

Step-by-step explanation:

When doing these types of problems I like to do this.

1500 ÷ 3 = 500 (We do this because you want to find out what 1/8 is)

Since 500 is 1/8 of the part, all you have to do is multiply 500 by 8

500 × 8 = 4000
