Answer:
infinite
Step-by-step explanation:
Let the linear equation in two variables be ax+by+c=0
Put values
![\\ \sf\longmapsto 1a+3b+c=0](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%201a%2B3b%2Bc%3D0)
![\\ \sf\longmapsto a+3b+c](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20a%2B3b%2Bc)
Hence for any values it has infinite number of solutions .
including x=1 and y=3
Answer:
1/2 but unsure
Step-by-step explanation:
I solved for X and I got 1/2 I want to verify what you are solving for so I could further help you
2 acute and 2 obtuse and 0 right angles
So let's start with the slope-intercept form of a linear equation. That is y = mx+b where m is slope and b is the y intercept. But, this is an inequality. So first we have to look at the way the graph is shaded. Since it is shaded upwards, you know that it is in the form of y ≥ mx + b. It tells you that the y-intercept is c because the line hits the y-axis at (0,c). Hence the equation is now y ≥ mx + c. But now, we have to find the slope of the graph. This is found by "rise over run" (I am sure you have heard of this). Count how many units the graph went down/up and how many units the graph went left/right and put it in fraction form of (units down or up) / (units left or right). Well it moves 2 units down so plug -2 into the top. It moved 1 unit right, so plug +1 into the denominator. So, the slope is -2. Hence we finally have our formula: y ≥ -2x + c which is the 5th choice.
Answer:
3, 3rd, 9
Step-by-step explanation:
The index of a radical is the small number next to it:
The radical has an index of 3.
This means that you must find the 3rd root:
To solve for x, find the 3rd root of 729.
This means what number multiplied by itself 3 times equal 729:
x = 9
