It’s 44.9ft
——————
——————-

EXPLANATION:

The person and the tree both cast shadows. The triangles which form are similar triangles, because the sun is shining from the same angle in the sky.
You can write this as a direct proportion. (height : shadow)

4. Write an equation for the line that is parallel to the given line and that passes

pentagon [3]

Answer:

$y=\frac{5}{2}x-14$

Step-by-step explanation:

Hi there!

<u>What we need to know:</u>

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

<u>1) Determine the slope (m)</u>

$y=\frac{5}{2}x-10$

In the given equation, $\frac{5}{2}$ is in the place of m, making it the slope. Because parallel lines have the same slope, the line we're currently solving for therefore has a slope of $\frac{5}{2}$ . Plug this into $y=mx+b$ :

$y=\frac{5}{2}x+b$

<u>2) Determine the y-intercept (b)</u>

$y=\frac{5}{2}x+b$

Plug in the given point (-6,-29) and solve for b

$-29=\frac{5}{2}(-6)+b$

Simplify -6 and 2

$-29=\frac{5}{1}(-3)+b\\-29=(5)}(-3)+b\\-29=-15+b$

Add 15 to both sides to isolate b

$-29+15=-15+b+15\\-14=b$

Therefore, the y-intercept is -14. Plug this back into $y=\frac{5}{2}x+b$ :

$y=\frac{5}{2}x-14$

I hope this helps!

Y+2 = -3(x – 4)<br> Complete the missing value in the solution to the equation. <br><br> (?, -2)

ss7ja [257]

Answer:

The missing value in the solution to

the equation will be:

$x=4$

Step-by-step explanation:

Given the equation

$y+2\:=-3\left(x\:-\:4\right)$

As the value of y = -2 is given.

so substituting the value y = -2 in the equation to find the missing value

$\left(-2\right)+2\:=-3\left(x\:-\:4\right)$

switch the sides

$-3\left(x-4\right)=\left(-2\right)+2$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$-3\left(x-4\right)=-2+2$

$-3\left(x-4\right)=0$

$\mathrm{Divide\:both\:sides\:by\:}-3$

$\frac{-3\left(x-4\right)}{-3}=\frac{0}{-3}$

$x-4=0$

$x=4$

Therefore, the missing value in the solution to

the equation will be:

$x=4$
