A line that passes through the point (–1, 3) has a slope of 2. Find another point on the line.

1 answer:

5 0

Easy, find the equation of the line,

Using y=mx+b form:

(-1,3) m=2

3= 2(-1)+b

3= -2+b
+2 +2

5=b

y=2x+5. This is your equation.

Now, plug in the coordinates:

(-3,2)

2= 2(-3)+5
2= -6+5
2= -1

NO

(0,5)

5= 2(0)+5
5=5

YES

(1,5)

5= 2(1)+5
5= 2+5
5=7

NO

(1,4)

4= 2(1)+5
4= 2+5
4=7

NO.

Thus, B, is your answer.

Solve 1. x2 + x - 6 = 0

ololo11 [35]

Answer:

x = -3 x=2

Step-by-step explanation:

x^2 + x - 6 = 0

Factor

What two numbers multiply to -6 and add to 1

3*-2 =-6

3+-2 =1

(x+3) (x-2) = 0

Using the zero product property

x+3 = 0 x-2 = 0

x = -3 x=2

Factor each completely. 10a² - 9a + 2

Sophie [7]

Answer:

a= $\frac{2}{5}$ or $\frac{1}{2}$

Step-by-step explanation:

Equate the equation to zero

$10a^{2}$ -9a+2=0

$10a^{2}$ -5a-4a+2=0

5a(2a-1)-2(2a-1)=0

Write out the factors

(5a-2)(2a-1)=0

Then equate each factor to zero

5a-2=0 OR 2a-1=0

5a=2 OR 2a=1

a= $\frac{2}{5}$ OR a= $\frac{1}{2}$

a= $\frac{2}{5}$ or $\frac{1}{2}$

Doria swam the 100-meter backstroke in 58.329 second. How do you express this time in words.show your work:

alex41 [277]

To solve this problem you must apply the proccedure shown below:

1. You have that the time, given in the problem above, is written in decimal form.

2. To express this time in words, you must begin from left to right. First, write the digits before the point (58) and after the points (329) as whole numbers. Then, finish it writting the place name of the last digit, as following:

(Note: The point is expressed as "and").

58.329: Fifty eigth and three hundred twenty nine thousandths.

Therefore, the answer is: Fifty eigth and three hundred twenty nine thousandths.

Find the center and the radius of the circle with the equation: x^2 +2x + y^2-2y-14 =0

FrozenT [24]

We need to convert the equation of the circle to standard form only then we can find the radius and the center of the circle.

$x^{2} +2x+ y^{2}-2y-14=0 \\ \\ 
x^{2} +2x+ y^{2}-2y=14 \\ \\ 
x^{2} +2(x)(1)+ y^{2}-2(y)(1)=14 \\ \\ 
 x^{2} +2x+1 + (y^{2}-2y+1)=14+1+1 \\ \\ 
(x+1)^{2}+(y-1)^{2} =16 
$

From this equation we can write:

Center of the circle is (-1,1) and the radius of the circle is 4.
