Answer:
D
Step-by-step explanation:
4x²= 32
x²= 32 ÷4 <em>(</em><em>÷</em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x²= 8
x= ±√8 <em>(</em><em>square</em><em> </em><em>root</em><em> </em><em>bith</em><em> </em><em>sides</em><em>)</em>
☆ A '±' symbol has to be added whenever we introduce a square root as the square of any number, positive or negative, would result in a positive number.
Step-by-step explanation:
800 times .035 (year 1) = 828
828 times .035 (y2) = 28.98 (add to 828)
856.98 times .035 = 29.99 (add to 856.98)
886.97 times .035 = 31.04 (add to 886.97)
918.01 times .035 = 32.13
918.01 plus 32.13 = 950.14
950.14
Answer:
4 is A
3 is C
Step-by-step explanation:
Answer:
y = -3x - 5
Step-by-step explanation:
The equation of a line is given as either:
where m is the slope, and b is the y-intercept.
or
where given that you have a point (x, y), y₁ is the y-value of the point, m is the slope, and x₁ is the x-value of the point.
We can just plug in the point (0, -5) into the second equation and -3 for the slope.
<em>However,</em> (0, -5) tells us that this point must be a <u>y-intercept</u>, since the x-value of that point is 0. So, we can also just plug into the first equation -5 for the y-intercept and -3 for the slope.
So, we get:
y = -3x + (-5)
Which simplifies into:
y = -3x - 5
