Answer:

y=1/2x+4

Step-by-step explanation:

to find the slope you need to know the change in y over the change in x

(0,4) and (8,8)

8-4/8-0

slope is 1/2

1.5/4x+1=0.4/x+4 PLEASE HELP ITS PROPORTIONS

Serhud [2]

Answer:

Proportion states that the two fractions or ratios are equal

Given the equation: $\frac{1.5}{4x+1} = \frac{0.4}{x+4}$

By cross multiply we get;

$1.5(x+4) = 0.4(4x+1)$

Using distributive property; $a\cdot (b+c) = a\cdot b+ a\cdot c$

$1.5x + 6= 1.6x + 0.4$

Subtract 0.4 from both sides we get;

$1.5x +5.6= 1.6x$

Subtract 1.5x from both sides we get;

$5.6= 0.1x$

Divide both sides by 0.1 we get;

$x = \frac{5.6}{0.1}$

Simplify:

x = 56

Therefore, the value of x that satisfy the equation $\frac{1.5}{4x+1} = \frac{0.4}{x+4}$ is, 56

For this case we have that by definition, the point-slope equation of a line is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

m: It's the slope

$(x_ {0}, y_ {0}):$ It is a point through which the line passes

According to the statement data we have:

$m = 5\\(x_ {0}, y_ {0}): (- 8,1)$

Substituting we have:

$y-1 = 5 (x - (- 8))$

By law of signs of multiplication we have to:

$- * - = +\\y-1 = 5 (x + 8)$

Answer:

The requested equation is: $y-1 = 5 (x + 8)$

Pls help I don’t understand

dmitriy555 [2]

The answer is c. $\frac{46}{9}$

a. $\frac{11}{5}=2.2$ (2.2≠5.11) (2.2 is not equal to 5.11)

b. $5\frac{1}{8}=\frac{5}{8}$ or 0.625 (0.625≠5.11) (0.625 is not equal to 5.11)

c. $\frac{46}{9} =5.11$ (5.11=5.11) (5.11 is equal to 5.11)

Therefore c is the answer

Find the area of the irregularly-shaped hexagon below

Ber [7]

let each box length be 1

for white triangle

area = ½bh

=½(4)(2)

for orange triangle

area=½(2)(3)

for blue marked boxes

each of the box

area=l²

=(1)²

there are 16 boxes

so the total area will be 16

total area of the hexagon = 4+3+16

=23 square units
