Answer:

X = 3

Step-by-step explanation:

$5x+4=-10x+19 \\ 4 - 19 = - 10x - 5x \\ - 15 = - 5x \\ - 5x = - 15 \\ x = \frac{ - 15}{ - 5} \\ x = 3$

Option C: -3 is the average rate of change between $x=-1$ and $x=1$

Explanation:

The formula to determine the average rate of change is given by

Average rate of change = $\frac{y_2-y_1}{x_2-x_1}$

We need to find the average rate of change between $x=-1$ and $x=1$

Thus, from the table, we have,

$x_1=-1$ , $y_1=5$

$x_2=1$ , $y_2=-1$

Thus, substituting these values in the formula, we get,

Average rate of change = $\frac{-1-5}{1+1}$

$=\frac{-6}{2}$

$=-3$

Thus, the average rate of change between $x=-1$ and $x=1$ is -3.

Hence, Option C is the correct answer.

Twins issac and isaiah were just born issac weighs 6 pounds 2 ounces and isaiah weighs 5 pounds 4 ounces.How many ounces do issa

Ivanshal [37]

Answer: $11\ \text{pounds}\ 6\ \text{ounces}$

Step-by-step explanation:

Given

Issac and Isaiah born weighing 6 pounds 2 ounces and 5 pounds and 4 ounces.

1 Pound is equivalent to 16 ounces

Issac weighs

$\Rightarrow 6+\dfrac{2}{16}\ \text{Pounds}$

Isaiah weighs

$\Rightarrow 5+\dfrac{4}{16}\ \text{Pounds}$

Their combined weight is

$\Rightarrow 6+5+\dfrac{2}{16}+\dfrac{4}{16}\\\\\Rightarrow 11+\dfrac{6}{16}\ or\\\\\Rightarrow 11\ \text{pounds}\ 6\ \text{ounces}$

Pls help!!!!The probability of hitting a target on a single trial is 40%,Find the probability of hitting the same target 5/8 tim

azamat

Probability hit=40%=4/10
probability no hit=1-p (hit)=1-4/10=6/10
probability= p(hit)+p(hit)+p(hit)+p(hit)+p(hit)+p (no hit)+p (no hit)+p (no hit)
probability=4/10×4/10×4/10×4/10×4/10×6/10×6/10×6/10
=0.0022
( I think but I'm not 100% sure)

Can someone help me with this problem please? Thank you!

Olenka [21]

Answer:

Step-by-step explanation:

since the Pythagorean theorem is

$c=$ √ $a^2+b^2$

b is the bottom line (48)

a is the right line (14)

c is the top line (c)

plug that in

$c =$ √ $14^2 + 48^2$

then do the exponets

$14^2$ = 14 * 14 = 196

$48^2$ = 48 * 48 = 2304

then add them together

196 + 2304 = 2500

$c =$ √2500

the sqrt of 2500 is 50 (50 * 50 = 2500)

c = 50

your answer is 50

hope this helps:)
