1-104. Solve each equation. Give solutions in both exact and approximate forms. HomeworkHelpa. X2+3x-3=0b. 3x2-7x=12
1 answer:
According to the given question we have the following equations:
a. x2+3x-3=0
b. 3x2-7x=12
a. X2+3x-3=0
The first step to calculate this equation is:
Move the -3 to the other side:
So, the equation would be:
X2+3x=3
x2+3x=5x
Therefore:
5x=3
x=3/5
a. The value of x would be 3/5
b. 3x2-7x=12
First step:
Multyply 3x to 2, so:
3x*2=6x
Next we can proceed to calculate the value of x:
6x-7x=12
-x=12
x=-12
b. The value of x would be -12

Answer:
Step-by-step explanation:
For this exercise is necessary to remember the following formula:
Where "V" is the speed, "d" is the distance and "t" is the time.
In this case you must solve for the time, then:
Based on the information provided in the exercise, you can identify that:
Therefore, knowing this, you can make the substitution into the formula .
Through this procedure you get that the equation that can be used to find the amount of hours "h" that it will take Sandra to drive "m" miles at her constant speed, is:
Answer:
11.2 feet
Step-by-step explanation:
Given: Height of platform (Opposite)= 5 foot
Distance of slope from the base of platform (adjacent)= 10 feet
Picture drawn to show the measurement.
Lets find the length of slope.
Using the Pythagorean theoram.
Subtituting the value in the formula.
⇒
⇒
Putting square root on both side
We know, √a²= a
⇒
∴ hypotenous= 11.18
Hence, the slope is 11.2 feet
