Answer:

$\sqrt{13}$

Step-by-step explanation:

<u>The two points:</u>

(0, 0) and (-3, -2)

<u>The distance:</u>

d = $\sqrt{(x2- x1)^2 + (y2 - y1)^2 }$
d = $\sqrt{(-3)^2 + (-2)^2}$ = $\sqrt{13}$

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4 by substituting x = 1 and x = 2. 6x + 11 3(x + 7) 2(3x + 16) 3x

2(3x+16)

Step-by-step explanation:

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4

4(x + x + 7) − 2x + 8 − 4

When x=1 , the expression becomes 4(1+1+7)-2(1)+8-4=38

When x=2 , the expression becomes 4(2+2+7)-2(1)+8-4=44

Plug in x=1 and check with each expression

6x + 11 =6(1) +11= 16

3(x + 7) = 3(1+7)= 3(8)= 24

2(3x + 16) = 2(3(1)+16)= 38 , we got same answer when x=1, now check with x=2

2(3x + 16) = 2(3(2)+16)= 44

3x + 16= 3+16= 19

If a line with a slope of -2 crosses the y-axis at (0, 3), what is the equation of the line?

Karo-lina-s [1.5K]

Answer: Option D

$y +2x = 3$

Step-by-step explanation:

The equation of a line in the form of "slope-interception" has the following form:

$y = mx + b$

Where m is the slope of the line and b is the interception of the line with the y axis.

In this case we know that the line has a slope of -2. Then $m = -2$ .

We also know that the line intercepts the axis y at the point (0, 3) therefore we know that:

$b = 3$ .

Finally the equation of the line will be:

$y = -2x + 3$

If we add 2x on both sides of the equation we get:

$y +2x = 3$

The answer is the option D

Are the two figures below similar? If so, how do you know?

artcher [175]

No because the scale factor is inconsistent while it would be neccecary to be consistent if it was similar. 19.9/15.3=1.3 while 29/25=1.16 which proves that they have an inconsistent scale factor.

PLEASE HELP This is solving Exponential and Logarithmic Equations I got the other ones, but I don’t even know what this says to

QveST [7]

Answer:

Step-by-step explanation:

We have

$e^\frac{x}{2}^l^n^3 = 5\\$

$ln(e^\frac{x}{2}^l^n^3) = ln(5)\\\frac{x}{2}ln(3) = ln(5)\\\frac{x}{2} = \frac{ln(5)}{ln(3)} \\x = \frac{2ln(5)}{ln(3)}$

$x = 2.929947041$

to the third decimal is 2.930 (i might be wrong on the rounding part)
