Answer:

y=2x-5

Step-by-step explanation:

y - 2x = -5
add 2x to both sides.
y=-5+2x

Answer:

y = 2x - 5 is a line. determine the two points that this line intersects with the axes then connect these points to graph it.

Step-by-step explanation:

Given y = 2x -5 set y = 0 then solve for the abscissa

y = 2x - 5

0 =2x - 5

2x=5

x = 5/2

we now have the point (5/2,0)

set now x = 0 then solve for ordinate

y = 2x - 5

y = 2(0) - 5

y = -5

we now have the point (0, - 5)

we now simply draw a line passing thru the two points ( 5/2, 0) and (0, - 5)

kindly see the graph of y = 2x - 5 with points (5/2, 0) and (0, - 5)

Hope this helps

By substituting the first equation into the second, we get:

2x + 5*(2x +3) = 3

The correct option is the second one.

Here we have the system of equations:

y = 2x + 3

2x + 5y = 3

You can see that the variable "y" is already isolated in the first equation, so we can just substitute it in the second equation:

2x + 5*(2x +3) = 3

This is what we can see in the second option, so we conclude that the second option is the correct one.

The angle x has a measure of 37

Angles are formed when two or more lines intersect. This in other words means that angles is the measure of space between the intersection of rays or lines

The given parameter is the figure

On the figure, we have the following angle measures

2x, 79, 32 and 5x

The sum of angles in a quadrilateral is 360 degrees

So, we have the following equation

2x + 79 + 32 + 360 - 5x =  360

Evaluate the like terms in the above equation

So, we have the following equation

-3x + 79 + 32  =  0

Evaluate the like terms in the above equation

So, we have the following equation

The greatest common divisor (24,6) is 6 and the least common multiple (24,6) is 24.

As per the question statement, the greatest common divisor of two integers is (x+2) and the least common multiple x(x+2). It is given that one of the integers is 24.

Let us assume that "b" is the value of other one.

greatest common divisor(24,b) = (x+2)

least common multiple(24,b) = x(x+2)

Formula:

greatest common divisor(24,b)*least common multiple(24,b) = 24*b

24*b = (x+2)*x(x+2)

[tex]b = \frac{x(x+2)^{2} }{24} \\[/tex]

Answer:

That’s the answer

Answer:

21 cups oil

14 cups soy sauce

7 cups orange juice

Step-by-step explanation:

Use 1 cup for 1 part. The original recipe as given with its small amounts would make a total of 3 + 2 + 1 = 6 parts, or 6 cups of sauce.

You want to make 42 cups.

42/6 = 7

The amount you want to make is 7 times the amounts in the ratio.

3 parts oil: 3 × 7 = 21: 21 cups oil

2 parts soy sauce: 2 × 7 = 14: 14 cups soy sauce

1 part orange juice: 1 × 7 = 7: 7 cups orange juice

Check: 21 + 14 + 7 = 42

The amounts above do make 42 cups in total.

Given that,

The line is horizontal. It means slope of this line is zero. We can use the point-slope form for a linear equation since we know the slope and the point (15, 21).

Point-slope form: [tex](y-y_{1}) = m(x-x_{1})[/tex]

Where,

m = slope and [tex](x_{1}, y_{1})[/tex] is the points.

For x = 28, the value of [y] such that [x] is directly proportional to [y] will be 112.

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. Mathematically, direct proportionality is represented by a straight line and it equation is of the form -

y = kx

k = y/x

where [k] is the constant

Given is the value of [y], which is directly proportional to the value of [x], and when [x] = 3.5, the value of [y] is 14.

We have the following data -

[y] = 14 at [x] = 3.5

Now, since [y] is directly proportional to [x], we cam write -

y = kx

k = y/x

k = 14/3.5.            [1]

Now, for x = 28, we can write the relation as -

y/x = k

k = y/28            [2]

Now, equating equation [1] and [2], we get -

14/3.5 = y/28

y = (14 x 28)/3.5

y = (140 x 28)/35

y = (140 x 4)/5

y = 28 x 4

y = 112

Therefore, for x = 28, the value of [y] such that [x] is directly proportional to [y] will be 112.

Amount of gas that Lou bought = 8.8 gallons

After adding interest the sum would be worth $657.51 .

Interest is the amount paid over and above the original amount to a lender or depositor by a borrower or deposit-taking financial institution at a predetermined rate in the domains of finance and economics (the amount borrowed).

Interest when the principal is $5 , time is 100 years and rate is 5%.

We know that from compound interest:

Amount = principal (1 + rate)ⁿ

Therefore

Amount = 5 (1 +0.05)¹⁰⁰

Amount = $657.5062...

Amount ≈ $657.51

Answer:

(0, -5)

Explanation:

The function is represented by f(x), and the line graphed would be y= f(x). In slope-intercept form, the equation of a line is given by y= mx +c, where m is the slope and c is the y-intercept.

Since we know that the line is linear, any two points along the line would give us the same slope value. Since y-intercepts occur at x= 0, let the y-intercept be (0, y).

[tex]\boxed{ \text{slope} = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

Slope between (-3, 1) and (1, -7)= slope between (-3, 1) and (0, y)

[tex] \frac{1 - ( -7 )}{ - 3 - 1} = \frac{y - 1}{0 - ( - 3)} [/tex]

[tex] \frac{1 + 7}{ - 4} = \frac{y - 1}{0 + 3} [/tex]

[tex] \frac{8}{ - 4} = \frac{y - 1}{3} [/tex]

[tex] - 2 = \frac{y - 1}{3} [/tex]

Multiply both sides by 3:

-2(3)= y- 1

-6= y -1

Add 1 to both sides:

y= -6 +1

y= -5

Thus, the y-intercept is (0, -5).

__________

Based on the image, however, we are to find the equation of the linear function in slope-intercept form.

The first step would be to find the slope between any two points, which would be -2. This is found using the slope formula, and we have calculated it above.

Substitute the value of the slope into y= mx +c:

y= -2x +c

The y-intercept can be found by substituting a pair of coordinates the line passes through.

When x= -3, y= 1,

1= -2(-3) +c

1= 6 +c

c= 1 -6

c= 5

The intercept is 5 because that is where the graph cuts the y axis.

PLEASE MARK AS BRAINLIEST IF YOU FOUND IT HELPFUL BECAUSE IT MAKES ME FEEL GOOD!

Step-by-step explanation:

y = mx + c;

The m equals the change in y divided by the change in x. If you choose left to right for y then you must do the same for x as well.

Δy = ( - 7 ) - ( - 15 ); Δx = 1 - 5;

Δy = - 7 + 15;

Δy = 8;

Δx = - 4;

m = 8 / - 4;

m = - 2;

y = - 2x + c;

Pick a point (x, y) and sub it into the equation. Make sure to use brackets when subbing.

- 7 = - 2( 1 ) + c;

- 7 = - 2 + c;

Add 2 to both sides.

- 7 + 2 = - 2 + 2 + c;

- 5 = c;

c = - 5;

The c is the intercept.

Based on the median and the centroid theorem, the length of WI is 6 units.

The line that joins the vertex of a triangle to the midpoint of the side it is directly opposite is called the median of a triangle.

According to the centroid theorem, since J is the centroid of triangle XYW, then:

the length of IE is 1/3 of the length of segment EW.

Thus, the equation that relates the length of the segments is;

IE = 1/3(EW)

Given that:

IE = 3 units

Now Substitute the value of IE into the equation:

3 = 1/3(EW)

3(3) = EW
