Solve using elimination?

Mathematics
1 answer:
Hatshy [7]3 years ago
3 0
Y-x=3
-y-4x=2 (I multiplied this equation by -1 so when I add I can eliminate a                            variable.) 
Now add them together. 
-5x=5
x=-1 now plug in x to solve for y
-y-4(-1)=2
y=2 so your answer is    (-1,2)

Which function models the area of a rectangle with side lengths of 2x – 4 units and x + 1 units? What is the area when x = 3?
Bingel [31]

Answer:

8

Step-by-step explanation:

Length = 2x-4

Width = x+1

Let x=3 and find the length and width

Length = 2*3-4 = 6-4 =2

Width = x+1= 3+1 =4

The  area is given by

A = l*w = 2*4 = 8

3(x - 4) = -3. Solve for x.
marshall27 [118]

Answer:

x = 3

Step-by-step explanation:

3(x - 4) = -3

Divide by 3

3/3(x - 4) = -3/3

x-4 = -1

ANSWER

y=\frac{2}{3}x+\frac{4}{3}

EXPLANATION

We want to find the equation of the straight line given on the graph.

The general form of a linear equation is given as:

y=mx+b

where m = slope; b = y-intercept

To find the slope, we apply the formula for slope:

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

where (x1, y1) and (x2, y2) are two points on the line

Let us pick (1,2) and (4,4)

Therefore, the slope is:

m=\frac{4-2}{4-1}=\frac{2}{3}

To find the equation, we now apply the point-slope formula:

y-y_1=m(x-x_1)

Therefore, we have that the equation of the line is:

\begin{gathered} y-2=\frac{2}{3}(x-1) \\ y-2=\frac{2}{3}x-\frac{2}{3} \\ y=\frac{2}{3}x-\frac{2}{3}+2 \\ y=\frac{2}{3}x+\frac{4}{3} \end{gathered}

That is the equation of the line.
