Find the missing factor 5y^2-4y-9=(y+1)

Mathematics
1 answer:
disa [49]3 years ago
8 0

Answer:

y = {1,2}

Step-by-step explanation:

5y^2 - 4y - 9 = y + 1

5y^2 - 5y - 10 = 0

5(y^2 - y - 2) = 0

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

y = {1,2}

PLZ HELP ASAP FEATURES OF A CIRLE FROM EXPANDED EQUATION
Lana71 [14]
First we need to convert the given equation to standard form, only then we can find the center and radius of the circle.

x^{2} + y^{2} +18x+14y+105=0 \\  \\ 
 x^{2} +18x+ y^{2}+14y=-105 \\  \\ 
 x^{2} +2(x)(9)+ y^{2}+2(y)(7)=-105 \\  \\ 
x^{2} +2(x)(9)+ 9^{2} + [y^{2}+2(y)(7)+7^{2}]  =-105+9^{2}+7^{2}  \\  \\ 
 (x+9)^{2}+ (y+7)^{2}=25  


The standard equation of circle is:

(x-a)^{2} + (y-b)^{2}= r^{2}

with center (a,b) and radius = r

Comparing our equation to above equation, we can write

Center of circle is (-9, -7) and radius of the given circle is 5

A parallelogram has a perimeter of 42 meters. Two sides are each 19.8 meters long. What is the length of the other two sides?
ValentinkaMS [17]
We first add both 19.8 by 19.8 and therefore, that would give us 39.6.

42 - 39.6 = 2.4.

2.4 ÷ 2 = 1.2

1.2 would be the length of each sides.

On a map, the scale shown is 1 inch: 20 miles. If a city is 900 square miles, what is the area of the city on the map?
WITCHER [35]

Answer:

2.25 square inches

Step-by-step explanation:

we know that

The scale is 1\ inch: 20\ miles

That means

1 inch on a map represent 20 miles in the city

so

An area of (1)(1)=1\ in^2 on a map represent an area of (20)(20)=400\ mi^2 in the city

Applying proportion

\frac{1}{400}\ \frac{in^2}{mi^2}=\frac{x}{900}\ \frac{in^2}{mi^2}\\\\x=900/400\\\\x=2.25\ in^2
