Answer:
x intercept is (3.75, 0) and y intercept is (0, 2.5)
Step-by-step explanation:
4x + 6y - 15 = 0
x int = (3.75, 0)
0*6 = 0
4x - 15 = 0
0 + 15 = 4x = 15
15/4 = 4x
x = 3 3/4 or 3.75
y int = (0, 2.5)
0*4 = 0
6y - 15 = 0
15 = 6y
15/6 = y
y = 2.5

Step-by-step explanation:
<u>Step 1: Define Equation</u>
7(2x - 5) = 21
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 7: 2x - 5 = 3
- Isolate <em>x</em> term: 2x = 8
- Isolate <em>x</em>: x = 4
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 7(2(4) - 5) = 21
- Multiply: 7(8 - 5) = 21
- Subtract: 7(3) = 21
- Multiply: 21 = 21
Here we see that 21 does indeed equal 21.
∴ x = 4 is the solution to the equation.
Setup: cos48 = x/25
25(cos48) = x
