The coordinates of the endpoints of line segments T'V' are; T'(-1, 2) and V'(0, 1).
What are the coordinates of the endpoints of the segment T'V'?It follows from the task content that the transformation involved in the formation of the image from the pre-image is dilation by a scale factor of 1/4.
It follows therefore that, given the coordinates of T and V from the task content are; (-4, 8) and (0,4), it follows that the coordinates of the endpoints as required are; T'(-1, 2) and V'(0, 1).

Answer:
∠C and ∠F are right angles
Step-by-step explanation:
To prove that two triangles are congruent using HL, one must have:
a right angle congruent,a leg congruent, and the hypotenuse (the side across from the right angle) congruent.For this problem, there are two sides of the triangle already congruent: one could be the hypotenuse (if the right angle were across from it), and the other congruent side could be a leg. So, if we can prove either that angles C & F are right angles, or that angles A & D are right angles, that would be enough to use HL congruence.
Hence, from the answer choices provided, proving that angle C and angle F are both right angles would be sufficient to prove the triangles are congruent via HL congruence.
Side note: Proving angles B and E would not be enough to use HL congruence, because the hypotenuse is always across from the right angle. So, if angle B were a right angle, it would mean that side AC was the hypotenuse (which hadn't yet been proven or stated to be congruent).
While not enough to prove triangle congruence via HL, if angle B and E were congruent at all (right angles or not), it would be enough to prove that the triangles were congruent by SAS (side-angle-side) because it would have proven that two sides and the included angle were congruent.

find the value of p in the given figure
The value of p is 60°
How to determine the valueThe figure given is a triangle and it is important to note that sum of angles in a triangle = 180 degrees
The other sides are gotten by;
Angle on a straight line = 180
110 + x = 180
x = 180 - 110
x = 70
The other interior angle
130 + y = 180
y = 180 - 130
y = 50
We have,
x + y + p = 180
70 + 50 + p = 180
120 + p = 180
p = 180 -120
p = 60°

Solving simultaneous equationsFrom the question, we are to solve the given system of equations
-7x + 4y = -32 -------- (1)
9x - 2y = 38 -------- (2)
From equation (2)
9x - 2y = 38
2y = 9x - 38
y = 4.5x - 19 -------- (3)
Substitute this into equation (1)
-7x + 4y = -32
-7x + 4(4.5x -19) = -32
-7x + 18x - 76 = -32
-7x + 18x = -32 + 76
11x = 44
x = 44/11
x = 4
Substitute the value of x into equation (3)

25) lan bikes 18 mph for 15 miles. Which is true? a. lan rode exactly 1 hour b. lan rode more than 1 hour C. lan rode less than 1 hour
Answer:
C. Ian rode less than 1 hour
Step-by-step explanation:
It never hurts to think about what the problem statement is telling you. Ian rode at a speed that would take him 18 miles in 1 hour.
InterpretationClearly, Ian would pass the 15-mile mark in a 1-hour ride before an hour had elapsed. If he only rode 15 miles, he rode less than 1 hour.
The actual time Ian rode is given by the relation between speed, time, and distance.
time = distance/speed
time = (15 mi)/(18 mi/h) = (15/18) h = 5/6 h
Ian's riding time was 5/6 of an hour, which is less than 1 hour.

Answer:
the answer to this problem is D:(-2,4)(1,1)
Answer:
B
Step-by-step explanation:
y = x² → (1)
y = 3x - 2 → (2)
substitute y = x² into (2)
x² = 3x - 2 ← subtract 3x - 2 from both sides
x² - 3x + 2 = 0 ← in standard form
(x - 1)(x - 2) = 0 ← in factored form
equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 2 = 0 ⇒ x = 2
substitute these values into (2) for corresponding values of y
x = 1 : y = 3(1) - 2 = 3 - 2 = 1 ⇒ (1, 1 )
x = 2 : y = 3(2) - 2 = 6 - 2 = 4 ⇒ (2, 4 )
