Answer:
-29
Step-by-step explanation:
-5x^2-6y^2
substitute the x and y values
-5(1)^2-6(2)^2
-5-6*4
-5-24
-29
Yes it is. "To the power of" just means you are multiply a number by itself how many times.

Answer:
Step-by-step explanation:
When the equation of the line is in the form ...
y = mx + b
the coefficient 'm' is the slope of the line, and the value 'b' is the y-intercept, the point on the y-axis where the line crosses.
We say the line is "steeper" when the magnitude of the slope is greater. Line B, with its slope of 7 will be steeper than line A, with its slope of 3.
the new slope is steeper
__
The y-intercept of line A is -3. The y-intercept of line B is +1, so it crosses the y-axis above the point where line A crosses. One could say that line B is shifted up, when referring to the y-intercept.
Answer:
Apply inverse law
a a⁻¹ = 1
The solution of the given linear equation is x = -6
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given equation -3 x-5=13
Adding '5' on both sides, we get
- 3 x - 5 + 5 = 13 + 5
- 3 x = 1 8
<u><em>step(ii):-</em></u>
apply inverse law
a a⁻¹ = 1
(- 3)(-3)⁻¹ x = 18 (-3)⁻¹
x = 18/-3 = -6
(or)
Dividing '-3' on both sides , we get
x =- 6
