A student says that the x-intercept of a line is (0,-10,). Is the student correct? Explain.

nataly862011 [7]

Answer:

Yes, the student is correct

Step-by-step explanation:

Given

$(0,-10)$

Required

Does it represent the x intercept

At the x intercept, the value of x is 0.

So, the function $(x,y)$ becomes $(0,y)$

$(0,-10)$ can be compared to $(0,y)$

Hence, the student is correct

Solve for x.<br> −8x+14≥60 OR −4x+50<58

Reika [66]

Answer: The solution is,

$x\leq -\frac{23}{4}$ or $x>-2$

Step-by-step explanation:

Given compound inequality,

-8x + 14 ≥ 60 or -4x + 50 < 58,

By the subtraction property of inequality,

-8x + 14 - 14 ≥ 60 - 14 or -4x + 50 - 50 < 58 -50,

-8x ≥ 46 or -4x < 8

By the division property of inequality,

$-x \geq \frac{46}{8}$ or $-x < \frac{8}{4}$

Using property a > b ⇒ - a < -b,

$x\leq -\frac{23}{4}$ or $x>-2$
