Answer:
B. TRUE.
(3, 2) is the intersection point of the graphs of
x + y = 5 and x - y = 1.
Step-by-step explanation:
Option B is TRUE because intersection point should satisfy both the equation
and in option be it comes true.
i.e x = 3 and y = 2 we have
3 + 2 = 5 and 3 - 2 = 1
5 = 5 and 1 = 1
Hence TRUE
A.
(3, 2) is the intersection point of the graphs of
3x + 2y = 5 and 3x - 2y = 1.
i.e x = 3 and y = 2 we have
3×3 + 2×2 = 5 and 3×3 - 2×2 = 1
13 ≠ 5 and 5 ≠ 1
Hence FALSE
C.
(5, 1) is the intersection point of the graphs of
3x + 2y = 5 and 3x - 2y = 1.
i.e x = 5 and y = 1 we have
3×5 + 2×3 = 5 and 3×5 - 2×3 = 1
21 ≠ 5 and 9 ≠ 1
Hence FALSE
D.
(5, 1) is the intersection point of the graphs of
x + y = 5 and x - y = 1.
i.e x = 5 and y = 1 we have
5 + 1 = 5 and 5 - 1 = 1
6 ≠ 5 and 4 ≠ 1
Hence FALSE
Dilation as it affects the size of a figure.
Volume of cube=side³
ok, so you need to know the difference or sum of cubes
a³+b³=(a+b)(x²-xy+y²)
so
(4p)³+(2q²)³=
(4p+2q²)((4p)²-(4p)(2q²)+(2q²)²)=
(4p+2q²)(16p²-8pq²+4q⁴)
3rd option
Answer:
Step-by-step explanation:
let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let 
be temperature at time t The temperature relative to time of waking up can be expressed as:
Hence, temperature relative to time of waking up is expressed as
Answer:
1 hour (60 minutes)
Step-by-step explanation:
If his speed remains the same, that means that this is a linear relationship. y increases at the same rate as x increases. Direct variation and all of that. Because this is a linear relationship, it can be solved using proportions. Set up the given info in a ratio with miles on the top and minutes on the bottom:
Now we want to know how long (unknown number of minutes) it will take him to go 12 miles. Keep miles with miles and minutes with minutes:
=
We can cross multiply now to get 4x = 12(20) and 4x = 240. That means that x=60. It will take him 60 minutes (1 hour) to go 12 miles.
