It’s false because, a system of linear equations has one solution when the graphs intersect at a point.
Answer:
HJ is diameter.
Step-by-step explanation:
Given Triangle HKJ is inscribed in the circle. we have to conclude about HJ if the triangle is a right triangle.
All the three sides are chord of the circle.
As given HKJ is right angled triangle i.e∠HKJ=90° and angle subtended by diameter in the semicircle is 90° implies HJ is diameter because if the HJ moves towards the angle then the given angle becomes acute and if moves away from the angle then the angle becomes obtuse which contradict the given information.
hence, the only possibility about the line HJ is that it is a diameter.
Answer
Find out the what is the ratio of students with pets to students without pets .
To prove
As given
of 60 students, 24 students have a pet.
Thus Total number of student = 60
students have pets = 24
students without pets = 60 - 24
= 36
Now ratio of students with pets to students without pets .

simplify the above

Therefore the ratio of students with pets to students without pets be 2:3 .
Hence proved
Answer:
The surface area of the red square is 180, and the surface area of the blue square is 328. So the full answer is 508.
Step-by-step explanation:
A = 2( width times length +height times length +height times width ) = 2(6 times 3 + 8 times 3 + 8 times 6)=180
A = 2(width times length + height times length + height times width) = 2(2 times 12 + 10 times 12 + 10 times 2) = 328
And 328 + 180 = 508.
