For #1 the answer would be ; " y = - x - 4 "
( you just have to plug in the given numbers to the slope intercept form )
Answer:
.9-1.5x
Step-by-step explanation:
Answer:
(-45,45,14)
Step-by-step explanation:
(r+v)*w=((9,8,3)+(6,7,-1))*(-3,3,7)=(15,15,2)*(-3,3,7)=(-45,45,14)
Does this help (I'm not sure of the rightness of this answer), if it did, please mark brainliest
Answer:
Feel free to copy and paste:
Use the slope-intercept form to find the slope and y-intercept. To do this, use y=mx+b. Plug the variables where m=1 and b=2. Slope of the line is m and y-intercept is value of b, so the slope is 1 while the y-intercept is (0,2). Any line can be graphed using two points, and using two x values to plug them into the equation to find the corresponding y values: 0=x+2 is (-2,0). Y-intercept is already known, so use the known values and make a table where x= -2,0 and y = 0,2. Now, graph the line using the slope, y-intercept, and known points (-2,0), (0,-2) to plot the graph. Coincidingly, the answer to solve your system of equations will be the x-intercept: (-2,0).

Step-by-step explanation:
<u>Step 1: Define</u>
f(x, y) = 2x - 3y + xy²
(3, -1) is x =3 and y = -1
<u>Step 2: Evaluate</u>
- Substitute: f(3, -1) = 2(3) - 3(-1) + 3(-1)²
- Exponents: f(3, -1) = 2(3) - 3(-1) + 3(1)
- Multiply: f(3, -1) = 6 + 3 + 3
- Add: f(3, -1) = 9 + 3
- Add: f(3, -1) = 12
