Answer:
x = -175
Step-by-step explanation:
Step 1: Define
h(x) = -25
h(x) = 1/5x + 10
Step 2: Substitute and Evaluate
-25 = 1/5x + 10
-35 = 1/5x
x = -175

Answer:
The computer can perform 1051050 calculations in 10 seconds.
Step-by-step explanation:
1. Put the quantity of calculations the computer can perform in 1 second:
2. Multiply the quantity of calculations by 10 seconds:
Note that the units of seconds are cancelled as they appear on the numerator and the denominator, and the final response unit is given in calculations number.
The computer can perform 1051050 calculations in 10 seconds.
Answer:
False
Step-by-step explanation:
We first write the equation in the form ax² + bx + c=0 which gives us:
3x² - 6x + 9=0
Given the quadratic formula,
x= [-b ±√(b²- 4ac)]/2a ,the discriminant proves whether the equation has real roots or not.
The discriminant, which is the value under the root sign, may either be positive, negative or zero.
Positive discriminant- the equation has two real roots
Negative discriminant- the equation has no real roots
Zero discriminant - The equation has two repeated roots.
In the provided equation, b²-4ac results into:
(-6)²- (4×3×9)
=36-108
= -72
The result is negative therefore the equation has no real solutions.
