Set up a ratio:
5/3 = 40 / 2x+10
Cross multiply:
5(2x+10) = 3(40)
Simplify:
10x+50 = 120
Subtract 50 from each side:
10x = 70
Divide both sides by 10:
x = 70/10
x = 7
Answer:
Y x 2
Step-by-step explanation:
2 x 1 simplified is 2 so 1 will be eliminated
Answer:
The upside down V symbol is known as a wedge. It represents a conjunction which is informally the "and". In other words,
Note how we can replace p with "the taxes are high" and replace q with "the job pays well" to arrive at the overall compound statement "The taxes are high and the job pays well".
Some logic textbooks will use an ampersand symbol & to be used in place of a wedge. It will depend on the notation that they, or your teacher, has set up.
Answer:
to find the x-intercept, set y to 0.
0 = 1/5x - 7
7 = 1/5x
35 = x
(35, 0)
to find the y-intercept, set x to 0.
y = 1/5(0) - 7
y = 0 - 7
y = -7
(0, -7)
The rule for is that the lines never meet THEYRE patroller
