Answer:
Val is right
Step-by-step explanation:
One of the solutions to k < 3 is k = -4. When you square that, you get ...
k² = (-4)² = 16
which is not less than 9.
_____
k < 3 and k² < 9 will have the same solution set for |k| < 3, but their solution sets will differ for k ≤ -3.
When performing operations on inequalities, one needs to be aware of the order preserving/changing effects of the operation. Whether squaring a value preserves order or not depends on the relative magnitudes:
- 2 > 1; 2² > 1²
- -1 < 1; (-1)² = 1²
- -2 < 1; (-2)² > 1²
- -2 < -1; (-2)² > (-1)²
Answer:
Step-by-step explanation:
First, we need to convert the equation into y-intercept form.
Divide all of the equation by 3.
y = 2/3x + 3
Now 3 is the y intercept, which is (0,3). Start graphing by making a point at (0,3). Next, we have the slope which is 2/3. Go up 2 units and then go 3 units to the right and plot your point. Repeat the second step where you go up 2 points and go 3 points to the right until you reach the end of the graph. Connect all the points with a straight line and you have your line. Hope this helps
Answer:
10.5 miles
Step-by-step explanation:
75 divided by 50 is 1.5
1.5 times 7 is 10.5
Answer:
x = 0 and x = 1
Step-by-step explanation:
When x = 0 and x = 1 both f(x) and g(x) have the same value, that is
f(0) = g(0) = 1 and
f(1) = g(1) =
The solution to f(x) = g(x) is x = 0 and x = 1
Y = 3x - 2
I assume this is what they mean;
3(1)- 2 = 1 for <span><span>x = 1
</span>Fill in the x's with the following numbers. so first... (x = 2)
</span>y = 3x - 2
3(2) - 2
multiply 3 and 2 and then minus 2
which equals 4 all together
y=4
therefore;
3(2) - 2 = 4
For x = 3
Fill in the x with 3 in the equation
3x - 2 = y
3(3) - 2 = y
9 - 2 = y
equals 7
so...
3(3) - 2 = 7
Do the same rule with number 4 :)
