Answer: A is correct

Step-by-step explanation:

Let the missing value be v

100% of v =500

100/100 × v = 500

v = 500%

Check:

100/100 × 500

= 500

Write the equation of the line in fully simplified slope-intercept form.

Nataliya [291]

Answer:

$y=-\frac{1}{4} x-6$

Step-by-step explanation:

The slope-intercept form is $y=mx+c$ , where m is the slope of the line and c is where the line crosses the $y$ -axis.

To calculate $m$ we can use the formula $m = \frac{dy}{dx}$ where $dy$ is the difference in $y$ between two points and $dx$ is the difference between $x$ .

Information we can get from the graph given: $c=-6$ . Since $c$ is the point at which the line crosses the $y$ -axis.

To find $m$ let's get two points from the graph.

Point 1: $(4,-7)$

Point 2: $(8,-8)$

Now use the equation $m = \frac{dy}{dx}$ .

$m = \frac{-7 - (-8)}{4-8} = -\frac{1}{4}$ .

Now we have $m$ and $c$ , let's put them back into the general equation.

$y=-\frac{1}{4} x-6$

NNADVOKAT [17]

Answer:

Step-by-step explanation:

A partir das informações fornecidas, as seguintes equações podem ser modeladas:

$X=5Y\\X+Y=54\\$

Resolvendo o sistema:

$Y+5Y=54\\Y=9\\X=9*5=45$

A diferença entre eles é:

$X-Y=45-9\\X-Y=36$

A diferença entre o maior número e o menor número é 36.
