What is a Linear equation?A linear equation is a equation that has degree as one.To find the solution of n unknown quantities n number of equations with n number of variables are required. A linear equation can be solved by doing operations with the same number on both sides of the equation.
Suppose the length of the rectangle be x.
Then, its width is given as 70% × x = 0.7x.
Since, the area of the rectangle is the product of length and width, the following equation can be written as,
x × 0.7x = 0.7x².
Hence, the required expression for the area of the rectangle is given as 0.7x².

When three squares are joined at their vertices to form a right triangle, the combined area of two smaller squares is the same as the area of the largest square find the side of the third square
Answer:
b = 12 cm
Step-by-step explanation:
The Pythagora's Theorem
The area of a square of side length x is
[tex]A = x^2[/tex]
We have three squares, two of which have side lengths of a=5 cm and b= 13 cm.
The combined area of the smaller squares is the same as the area of the largest square. We cannot say at first sight which square is the largest, we'll assume the square of side length of 13 cm is the largest one. Thus:
[tex]5^2+b^2=13^2[/tex]
Where b is the unknown side length.
The above expression corresponds to the Pythagora's Theorem formula. Solving for b:
[tex]b^2={13^2-5^2=169-25=144[/tex]
[tex]b=\sqrt{144}[/tex]
b = 12 cm

Which relation is a function?
Answer:
A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Answer:
244 ft²
Step-by-step explanation:
Rectangle Base Area: 6•4=24
Rectangle Side Area: 8•10=80; 80•2(sides) = 160
Triangle Sides Area: (10•6=60); 60/2(area of triangle) = 30; 30•2(sides)=60*

Draw
Click or tap the graph to plot a point.
Step-by-step explanation:
Given system of equations are :
-3y = x+5 ....(1)
y = 2x+2 ...(2)
We need to find the solution of the equations.
Multiply equation (2) by 2.
-6y = 2x+10 ...(3)
Subtract equation (2) and (3).
y-(-6y)= 2x+2-(2x+10)
7y=2x+2-2x-10
7y=-8
y = 8/7
Put the value of y in equation (2)
[tex]\dfrac{8}{7}=2x+2\\\\\dfrac{8}{7}-2=2x\\\\x=\dfrac{\dfrac{-6}{7}}{2}\\\\x=\dfrac{-3}{7}[/tex]
Hence, this is the required solution.

What is the slope? (IXL)
Answer: a=mx+b
Step-by-step explanation:
PPLSS HELLP!! y=___x+___
Answer:
y= 1x-5
Step-by-step explanation:
This grpah shows a linear equation, for which the formula is y=mx+b. M is the slope, and b is the y-intercept, which means the point on the y-axis when x is zero.
So far= y=_x-5
Now to find the slope, you can take 2 points and use the slope formula, which is [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
I used the points (1,-4) and (0, -5)
(1,-4)
[tex]x_{2} , y_{2}[/tex]
(0,-5)
[tex]x_{1} ,y_{1}[/tex]
Plug into formula
[tex]\frac{-4-(-5)}{1-0}[/tex]
negative minus negative becomes a positive
[tex]\frac{-4+5}{1}[/tex]
[tex]\frac{1}{1}[/tex]
The slope is 1, so the equation of the graph is
y= 1x-5

Pascha is factoring the polynomial, which has four terms.
3x3 – 15x2 + 8x – 40
3x2(x – 5) + 8(x – 5)
Which is the completely factored form of her polynomial?
(3x2 – 5) (x + 8)
(3x2 – 8) (x + 5)
(3x2 + 8) (x – 5)
(3x2 + 5) (x – 8)
Answer:
[tex](3x^2 + 8)(x - 5)[/tex]
Step-by-step explanation:
Given
[tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
Required
Complete the factorization
[tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
When an equation is factorized as:
[tex]a(b + c) + d(b + c)[/tex]
The complete expression is:
[tex](a + d)(b + c)[/tex]
Apply this logic in [tex]3x^3 - 15x^2 + 8x - 40 = 3x^2(x - 5) + 8(x - 5)[/tex]
By comparison:
[tex]a = 3x^2; b = x; c = -5; d = 8[/tex]
So, we have:
[tex]3x^3 - 15x^2 + 8x - 40 = (3x^2 + 8)(x - 5)[/tex]
Hence,
[tex](3x^2 + 8)(x - 5)[/tex] is the complete factor

what is the slope-intercept equation of the line that goes through the points 1, 5 and 2, 8
Answer:
The slope-intercept equation of the line that goes through the points (1, 5) and (2, 8) is [tex]\mathbf{y=\frac{3}{2}x+\frac{7}{2} }[/tex]
Step-by-step explanation:
We need to find the slope-intercept equation of the line that goes through the points (1, 5) and (2, 8)
The general equation for slope intercept form is [tex]y=mx+b[/tex] where m is slope and b is y-intercept
Finding slope
Slope can be found using formula [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x _1=1, y_1=5, x_2=2, y_2=8[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-5}{2-1}\\Slope=\frac{3}{2}[/tex]
So, we get slope [tex]m=\frac{3}{2}[/tex]
Finding y-intercept
y-intercept can be found using slope [tex]m=\frac{3}{2}[/tex] and point (1,5)
[tex]y=mx+b\\5=\frac{3}{2}(1)+b\\b=5- \frac{3}{2}\\b=\frac{10-3}{2}\\b=\frac{7}{2}\\[/tex]
So, we get y-intercept [tex]b=\frac{7}{2}[/tex]
Equation of line
So, equation of line having slope [tex]m=\frac{3}{2}[/tex] and y-intercept [tex]b=\frac{7}{2}[/tex] is:
[tex]y=mx+b\\y=\frac{3}{2}x+\frac{7}{2}[/tex]
The slope-intercept equation of the line that goes through the points (1, 5) and (2, 8) is [tex]\mathbf{y=\frac{3}{2}x+\frac{7}{2} }[/tex]

Naomi wants to buy a new computer for $840. She is considering two payment plans that require weekly payments.
Part A:
Write a linear equation that models each payment plan. Write your answers in slope intercept form. Explain why you decided which one is your slope and which one is your y-intercept.
Plan A: $180 down $60/wk payments
Plan B: $0 down $70/wk payments
Answer:
Linear equations take the form: y = mx + c
y is the dependent variable i.e the money that Naomi has to pay in total.
x is the independent variable which in this case is weeks.
m is the slope and this shows the change as a result of x. It should therefore represent the weekly payment as this is increases per week.
c is a the y-intercept which means its a fixed figure that doesn't change. It will therefore be the down payment because that does not change.
Plan A:
Naomi wants to pay $840. Using the formula format and explanation above (replace x with w so it makes more sense), the formula will be:
840 = 60w + 180
Plan B:
This has no down payment so there will be no y-intercept.
840 = 70w
