Answer:
Third bar graph.
Step-by-step explanation:
Given : 5x + 7.5 = 15.
To find : Which bar diagram represents the equation.
Solution : We have given 5x + 7.5 = 15
In the equation we can see sum of 5x and 7.5 is 15 .
By the bar graph combination box of 5x and box of 7.5 is equal to the box of 15.
Then Third bar graph represent the equation .
Two pink boxes of 5x and 7.5 and one blue box of 15.
Therefore, Third bar graph.
What do you mean by "solve this?" Until you set f(x) = to some constant number, you don't have an equation and thus can't expect to find solutions.
Why don't we take <span>3x^2-18x+27 and set it = to 0, and only then try to solve this equation?
</span><span>3x^2-18x+27 = 0. Dividing both sides by 3, we get x^2 - 6x + 9= 0, which can be factored as
(x-3)^2 = 0. Taking the sqrt of both sides, we get x-3 = 0. Actually, there are 2 roots: 3 and 3. Again, this statement is true only if we set </span><span>3x^2-18x+27 = to 0.</span>
Answer: 6 = t
Step-by-step explanation: To get <em>t</em> by itself since -3 is being multiplied by <em>t</em>, divide both sides of the equation by -3.
On the left, -18 divided by -3 is 6 and on the right, the -3's cancel.
So <em>6 = t</em>.
