The input is the x-coordinate and the output is the y-coordinate. If the input is 4, plug 4 into the x variable to find the output, y.
y=3(4)-5
y=12-5
y=7
The output is 7.
-2x^2 + 5x -3 =0
Find the discriminate:
In the given formula a = -2, b = 5 and c = -3
The discriminate is found using the formula b^2 - 4(ac)
Replace the letters with their values:
5^2 - 4(-2*-3)
25 - 4*6
25-24 = 1
When the discriminate is greater than or equal to 0, there are two real solutions.
The answer is c) 2
Answer:
570 cm³
Step-by-step explanation:
Check the rule in your picture about Calculating the volume of a prism:
Volume = (2×15)×19
= 570
Answer:
90°
i went on a whim and guessed it was a right angle, sorry I can't provide reasoning! but it is for sure 90°
Step-by-step explanation:
14x + 5 + 90 = 165
14x + 95 = 165
-95 -95
14x = 70
/14 /14
x = 5
14(5) + 5 +90 = 165
70 + 95 = 165
165 = 165
