Answer:
14x+35
Step-by-step explanation:
Answer:
x=3 and y=−4
Step-by-step explanation:
Solve4x+y=8for y:
4x+y=8
4x+y+−4x=8+−4x(Add -4x to both sides)
y=−4x+8
Step: Substitute−4x+8 for y in 5x+2y=7:
5x+2y=7
5x+2(−4x+8)=7
−3x+16=7(Simplify both sides of the equation)
−3x+16+−16=7+−16(Add -16 to both sides)
−3x=−9
-3x/-3=-9/-3
(Divide both sides by -3)
Step 2: Substitute 3 for x in y=−4x+8:
y=−4x+8
y=(−4)(3)+8
y=−4(Simplify both sides of the equation)
<span>P(4, -4) ----> (-4, 7)
x- axis from 4 to -4 ; move to the left 8 units.
y-axis from -4 to 7 ; move up 11 units
</span><span>D. left 8; up 11
</span><span>C(3, -1) translated to the left 4 units and up 1 unit.
from 3 of x-axis move to the left 4 units to arrive at -1
from -1 of y-axis move up 1 unit is to arrive at 0.
(xy) </span>→ (x-4, y + 1) (-1,0) Choice D.
Answer:
(a)h(g(133))
(b)f(j(6.82))
Step-by-step explanation:
(a)Area of a circle whose circumference is 133 cm.
Since g(C) represents the radius (in cm) of a circle whose circumference is C cm.
- The radius of the circle whose circumference is 133 cm = g(133)
h(r) represents the area of a circle whose radius is r cm.
Therefore, the area of a circle whose circumference is 133 cm is:
h(g(133))
(b)Circumference of a circle whose area is
j(A) represents the radius (in cm) of a circle whose area is A .
- The radius of the circle of area = j(6.82)
f(r) represents the circumference (in cm) of a circle whose radius is r cm.
Therefore:
- Circumference, f(r) = f(j(6.82))
The circumference of a circle whose area is =f(j(6.82))
