PLS HELP ILL GIVE BRAINLIEST

Mathematics
1 answer:
Blizzard [7]3 years ago

Hi there.

The answer is f(0) = 3.

Explanation:

Given 2 functions with given domains.

f(x) = 5x - 1

where x < -2

f(x) = x + 3

where x >= -2

Evaluate the value of f(x) when x = 0. Therefore, f(x)= 5x-1 cannot be used as the given x = 0 is greater than its domain.

Thus, our main function is f(x) = x+3

Evaluate the value by substituting x = 0 in the function.

f(0) = 0 + 3 \\ f(0) = 3

Thus, the answer is f(0) = 3

Please Help.<br> Write the equation of linear Inequalities to represent each graph.
DerKrebs [107]

Green Line:

This is a horizontal line at x = 0, so it would be:

x ? 0      

Since the shaded area is going to the left of 0 (this means x is negative):

x ≤ 0


Blue Line:

The shaded area is below the line, so:

y ≤ mx + b

When x = 0, y is -5.

y ≤ mx - 5

From each point, you go up 3 units, and to the right 4 units, so the slope is \frac{3}{4}.


y\leq \frac{3}{4}x-5

How do you factor x squared minus 100
Alina [70]

Answer:

(x - 10)(x + 10)

Step-by-step explanation:

x² - 100 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Hence

x² - 100

= x² - 10² = (x - 10)(x + 10)

Help me please ASAP
Mashutka [201]

Answer: \frac{5}{35}

Step-by-step explanation:

Since, the total number of contestant = 7,

Thus, the probability that out of 3 contestant, me and my friend is chosen

= \frac{2_C_2\times 5_C_1}{7_C_3}

= \frac{\frac{2!}{2!0!}\times \frac{5!}{1!\times 4!}}{\frac{7!}{4!\times 3!}}

= \frac{1\times 5}{\frac{7\times 6\times 5\times 4!}{4!\times 6}}

=  \frac{5}{35}

⇒ Third Option is correct.
