2x+ 3 / 5= y<br> rearrange to make x the subject

Elza [17]

Answer:

Step-by-step explanation:

Given the equation 2x+ 3 / 5= y

Cross multiply

2x+3 = 5 * y

2x+3 = 5y

Subtract 3 from both sides

2x+3-3 = 5y - 3

2x = 5y-3

Divide both sides by 2

2x/2 = (5y-3)/2

x = (5y-3)/2

Hence the value of x is (5y-3)/2

Please answer correctly it’s urgent!!

bearhunter [10]

Answer:

Perimeter: 26 units

Area: 36 units

Step-by-step explanation:

EH = 4 units

HG = 9 units

GF = 4 units

FE = 9 units

Add them all up to find the perimeter

4 + 4 + 9 + 9 = 26

Then multiply the side by length to get the area

4 * 9 = 36

Graph the function shown g(x)=-|x-4|

il63 [147K]

Using translation concepts, the graph of g(x) = -|x - 4| is shown at the end of the answer.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The graph of g(x) = -|x - 4| is the graph of f(x) = |x| with these following changes:

Reflection over the x-axis.

Shift right of 4 units.

At the end of the answer, the graph shows functions f(x) in red and g(x) in blue.

Write an equation in point-slope form of the line through point P(-4, 7) with slope -4.

IrinaVladis [17]

Answer:

y - 7 = -4(x + 4)

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-4,7) and has a slope of -4.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was -4. So you can right away fill in the equation for a line somewhat to read:

y=-4x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-4,7). When x of the line is -4, y of the line must be 7.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,7).

So, why not plug in for x the number -4 and for y the number 7? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-4,7). y=mx+b or 7=-4 × -4+b, or solving for b: b=7-(-4)(-4). b=-9.
