Choose the inequality that represents the following graph

Strike441 [17]

Answer:

Step-by-step explanation:

1) Check whether the graph is inclusive or exclusive. Inclusive graphs are equal to or greater/less than, whereas exclusive graphs are just greater/less than. A filled circle is inclusive, and a non-filled circle is exclusive. We see that in the graph, the circle is filled meaning it is inclusive. Secondly, we see that the number line goes forever when it is greater than(or equal to) 3. From these two pieces of information, we see that the answer is choice D.

I need help solving for x: log x = 2.46 - 1.12 * log y

Mariulka [41]

$\bf log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)
\\\\\\
% Logarithm of exponentials
log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)
\\\\\\
{{ a}}^{log_{{ a}}x}=x\impliedby \textit{log cancellation rule}\\\\
-----------------------------\\\\$

$\bf log(x)=2.46-1.12log(y)\iff log_{10}(x)=2.46-1.12log_{10}(y)
\\\\\\
log_{10}(x)=2.46-log_{10}(y^{1.12})\implies log_{10}(x)+log_{10}(y^{1.12})=2.46
\\\\\\
log_{10}(x\cdot y^{1.12})=2.46\implies 10^{\cfrac{}{}log_{10}(x\cdot y^{1.12})}=10^{2.46}
\\\\\\
xy^{1.12}=10^{2.46}\implies \boxed{x=\cfrac{10^{2.46}}{y^{1.12}}}$

For each quadratic function, find the domain range vertex and axis of symmetry y=(x-1) squared +1

Arada [10]

$y=(x-1)^2 +1 \\ \\ For \ the \ quadratic \ function \\ \\ f(x) =a(x-h)^2+k \\ \\ where \ a, \ h \ and \ k \ are \ real \ numbers \ with \ a \neq 0 , \\ \\ the \ vertex \ is \ (h,k) =(1,1) \\ \\ a \ symmetry \ about \ the \ vertical \ line \ x = h \\ \\ x= 1$

Determine the intercepts of the line.

spayn [35]

ANSWER:
y intercept = (0,-6/5)
x intercept = (-3,0)

EXPLANATION:
To find the y intercept you have to substitute the x with zero because the y intercept always lies on the y axis which means that they will always have the coordinates (0,y)
The same goes for the x intercept. To find the x intercept you have to substitute the y with zero because the x intercept always lies on the x axis which means that they will always have the coordinates (x,0)

WORKING OUT:
Given=2x+5x= -6

The y intercept)
x=0
2(0)+5y= -6
5y= -6
y = -6/5 (divide each side of the equation by t to get the y alone)
y intercept = (0,-6/5)

The x intercept)
y=0
2x+5(0)= -6
2x= -6
x = -3 (divide each side of the equation by t to get the x alone)
x intercept = (-3,0)
