The answer is C.
Note when Soro divides both sides by -2.5 to solve the equation. When multiplying/dividing by a negative number, one should always reverse the inequality sign, but Soro forgot to do this.
-2.5x≥-30
After this step, the answer SHOULD HAVE been:
x≤12
Let me know if you need any clarifications, thanks!
Step-by-step explanation:
When the inequality uses < or >, it is a broken line.
For the point (0, 0) it means that x = 0 and y = 0.
Since (0) < (0)² + 4(0) + 5 is true, the point is part of the solution.
Answer:
y=-5/3x-6.5
Step-by-step explanation:
Answer:
1, -5, -14
Step-by-step explanation:
Domain is the x-axis, and range is the y axis.
So plug in the x values (domain values) to the equation.
The value of x according to the equation in the task content is; -5.35 or -10.65.
<h3>What is the value of x in the equation?</h3>
The equation given in the task content is; (x + 8)² -7 = 0.
Hence, the equation can be solved as follows;
(x + 8)² - 7 = 0
x² + 16x +64 -7 = 0
x²+ 16x +57 = 0
By solving by means of the quadratic formula, we have;
x = -5.35
x = -10.65
