What is the solution of the equation?-10 + sqrt x+8 = -4

Answers

Answer 1

Answer: $D:x+8\geq0\to x\geq-8\n\n-10+√(x+8)=-4\ \ \ /+10\n\n√(x+8)=-4+10\n\n√(x+8)=6\iff x+8=36\n\nx=36-8\n\nx=28\in D$

I tried doing the way I did in school but also on ---- and got the same answer so sorry if it's wrong

Answer:

-3/2

Step-by-step explanation:

4x-6y=12

-6y=12-4x

6y=4x-12

y=2/3x-2

Slope= 2/3

Perpendicular Slope= -3/2

The perpendicular line's slope is the opposite reciprocal of the original slope, so you answer is -3/2.

Answer:

The first and 3rd are functions, but the second and fourth are not functions.

Step-by-step explanation:

To see if something is a function, use the vertical line test. If there are multiple y coordinates for a singular point for x, it is not a function.

What is the y-intercept of the line y + 11=2(x+1.5)

Answers

Answer:

-8

Step-by-step explanation:

Turn the equation into slope intercept form [ y = mx + b ]

y + 11 = 2(x + 1.5)

~Distribute right side

y + 11 = 2x + 3

~Subtract 11 to both sides

y = 2x - 8

"b" represents the y-intercept, so, the y-intercept is -8.

Diep bought a baguette loaf of bread 65 centimeters long. For lunch every afternoon, he cuts 15 centimeters of bread for his sandwich. Diep wants to determine the length of the loaf of bread, l, after d days. What is the equation of the scenario? Is the graph of the equation continuous or discrete?

Answers

Given that the original length of the baguette is 65, and for each day 15 gets cut off, we have the functionl(d) = 65 - 15dwhere d is a positive integer representing the nth day. As a matter of fact, the possible vaalues for d are 0, 1, 2, 3, and 4. Since on the 5th day, there won't be enough baguette anymore. This shows that the function l(d) is not continous since only certain points satisfy the condition.Thus, the function is l(d) = 65 - 15 where {d| 0 ≤ d ≤ 4} and it is discrete.
