Answer:y = 3x + 5 is a linear equation in two variables and it has infinite possible solutions.
Step-by-step explanation:
To do this, we plug -1 in as x and -3 in as y. If the two sides are equal, (-1, -3) would satisfy y = x + -2. If they aren't equal, it doesn't satisfy the equation. We get:
-3 ? -1 + (-2);
and so,
-3 does indeed equal -3.
Thus, the point (-1, -3) satisfies the equation y = x + -2
Answer:
Step-by-step explanation:
For a, you need to plugin -9 into the equations inside the boxes and solve.
y = x^2 + 3, y = 9^2 + 3, y = 81 + 3, y = 84.
y = √x - 2, y = √9 - 2, y = 3 - 2, y = 1.
For b, It's only possible for the second equation to output 0, as for the first, it's impossible for x^2 to equal -3 and add to 3 to get 0. For the second equation you can plug in 4 to get 2 - 2, which gives 0.
Answer:
-5/7
Step-by-step explanation:
remember slope is eqaul to rise over run.
6-11 = -5 so it rose down by 5 units
10 - 3 = 7 so it ran 7 units
thus
slope= -5/7
Look at the key to figure out which colors represent taxes. 29% and 6% are the percentages for federal and state taxes. To find the percentage of all the expenses other than taxes, just subtract them from 100%
100-29-6= 65%
