HELP PELASE ILL MARK BRAINLIEST AND POINTS!

Mathematics
1 answer:
UNO [17]2 years ago
5 0

\qquad\qquad\huge\underline{{\sf Answer}}

Both the given lines in graph intersect at point (5 , -2), the point must satisfy both the equations.

and if we check the options, we will observe that D. option has both the equations that satisfy the given conditions.

that is ~

\qquad \sf  \dashrightarrow \: x + y = 3

put y = - 2,we will get :

\qquad \sf  \dashrightarrow \: x - 2 = 3

\qquad \sf  \dashrightarrow \: x = 5

so, 1st equation satifys the condition. let's check out 2nd one.

\qquad \sf  \dashrightarrow \: x + 2y = 1

put y = -2

\qquad \sf  \dashrightarrow \: x + (2 \times  - 2) = 1

\qquad \sf  \dashrightarrow \: x - 4 = 1

\qquad \sf  \dashrightarrow \: x = 5

Hence, we can conclude that the Correct choice is D

How do I solve 3/10+2.125 <br> Converted into fractions
ahrayia [7]

Answer:

97/40

Step-by-step explanation:

so 2.125= 17/8

3/10+17/8 need to find common denominator so

times 8/8 to 3/10

times 10/10 to 17/8

24/80+170/80= 194/80 (common denominator so can add)

divide 194/80 because want reduce form

97/40 is the answer

(When i look at it now i can just time 4/4 and 5/5 but its ok this still gets the answer)

Find the equation of the circle that has a diameter with endpoints (7,3) and (7,-5)
muminat

Answer:

(x-7)² + (y+1)² = 4² or (x-7)² + (y+1)² =16

Step-by-step explanation:

1) coordinates of the center

x0=(x1+x2)/2=(7+7)/2=7

y0=(y1+y1)/2=(3-5)/2 = -1

(7, -1) - coordinates of the center

2) radius of the circle

length of the diameter =√((x2-x1)²+(y2-y1)²)=√((7-7)²+(-5-3)²)=√(8)²= 8

r = length of the radius = length of the diameter / 2 = 8/2 = 4

3) the equation of the circle

(x-x0)² + (y-y0)²= r²

(x-7)² + (y+1)² = 4²=16
