Answer:
x = (4 + 2√34)/10, x = (4 - 2√34)/10
Step-by-step explanation:
5x² - 4x = 6
Subtract: 5x² - 4x - 6 = 0
Quadratic formula: x = (4 ± √(16 - 4*5*(-6)))/10
Multiply: x = (4 ± √(16 + 120))/10
Simplify: x = (4 ± 2√34)/10
Hello :)
Answer: x=11
Measure angel BAD= 122
Explanation:
To find X you have to make an equation
10x-49=5x+6
And then you solve for x
To find the angel measure of BAD, you have to add bac and cab to get bad
Bac= 10(11)-49 which equals 61
Cab= 5(11)+6=61
61+61= 122
Which is the measure of BAD
I hope this helps and have a wonderful rest of your night
Answer:
Step-by-step explanation:
We can solve the first equation, f of -3. The value of the function f is , and plugging in -3 gets us , this results in 10 divided by negative 2, which is negative 5.
Now, we must solve g of negative one third. The function g is defined as . Plugging in negative one third into the question gets us
9 times negative one third is -3, and -3 minus 15 is -18. The absolute value of -18 is 18.
Now, we must solve h of negative 2, and h is defined as . Plugging in negative 2, we have . Negative 8 times negative 2 is positive 16, and 16 minus 3 is 13. The answer is the square root of 13
1/2 as a decimal is .5 ( it means .50) hoped it helped
Every angle of a square equals 90 degrees.
2x - 4 = 90 3y + 6 = 90
2x = 90 + 4 3y = 90 - 6
2x = 94 3y = 84
x = 94/2 y = 84/3
x = 47 y = 28
so x = 47 and y = 28
