X=17-4y y=x-2 answer by substitution

Mathematics
1 answer:
sashaice [31]3 years ago

Answer:

x=5,y=3

Step-by-step explanation:

the first step is to decide whether you want to substitute y and find x, or substitute x and find y.

(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).

for example, let's substitute y into the first equation:

x=17-4*(x-2)

so now,we will organize the equation:

x+4x=17+8

5x=25/(÷5)

x=5

now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:

y=5-2

y=3

Find a solution of the linear inequality.<br> y&gt;_4x-5
irga5000 [103]

Answer:

(0,0) is among the solutions

Step-by-step explanation:

The given inequality is y\ge4x-5

A solution to this inequality is any ordered pair that satisfies the inequality.

Let us check for x=0 and y=0

We substitute to get:

0\ge4*0-5

0\ge-5....This is true.

Therefore (0,0) is a solution to the given inequality.

There are infinitely many solutions.

Will Mark The Brainliest. Write an equation of the line graphed in slope-intercept form using the variables x and y.
baherus [9]

Answer:

\boxed{y=-2x+5}

Step-by-step explanation:

The equation in slope-intercept form is given by:

y=mx+c

where m is the slope and c is the y-intercept.


The given line passes through so many points. We can use any two these points to find the slope of the line.

The line passes through (x_1,y_1)= (1,3) and (x_2,y_2)=(2,1).

The slope is given by;

m=\frac{y_2-y_1}{x_2-x_1}.


\Rightarrow m=\frac{1-3}{2-1}.


\Rightarrow m=\frac{-2}{1}=-2.

The y-intercept from the graph is c=5


Our equation finally becomes;

y=-2x+5

A certain forest covers an area of 3100. Suppose that each year this area decreases by 4.75% . What will the area be after 7 yea
e-lub [12.9K]

Answer:

Step-by-step explanation:

This can be represented as exponential decreasing function.

   y = a(1 - r)t

       a = starting amount

       r = rate

       t = years

   y = 1600(1 - .0725)15

     = 1600(.9275)15

     = 1600(.32337673)

     = 517.40

In 15 years,  the forest will shrink in size to 517.40 km2

Can i please get help with this
geniusboy [140]

Step-by-step explanation:

Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.

52 = ½ (x − 38)

x = 142

Arc angles add up to 360.

360 = 80 + 38 + z + x

z = 100

Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.

y = x/2

y = 71
