Answer:
The area of the trapezoid is 57.5 in.²
Step-by-step explanation:
The given information of the trapezoid are;
The vertices of the trapezoid = QRST
The altitude of the trapezoid = 5 in.
The shape the altitude divides the trapezoid into = A square and an isosceles right triangle
The long side of the rectangle = 9 in.
Therefore, we have;
The legs of an isosceles right triangle are equal
Given that one of the legs of the isosceles right triangle = The altitude of the triangle = 5 in.
Therefore, for the isosceles triangle, the length of the other leg = 5 in.
Therefore;
The area of the right triangle = 1/2 × Base × Height (altitude)
The area of the right triangle = 1/2 × Leg × leg = 1/2 × (Leg)²
∴ The area of the right triangle = 1/2 × 5 in. × 5 in. = 12.5 in.²
The length of the rectangle is given as l = 9 in.
The height of the rectangle, h = The altitude of the rectangle = 5 in.
The area of the rectangle, A = l × h
∴ The area of the rectangle, A = 9 in. × 5 in. = 45 in.²
The area of the trapezoid = The area of the right triangle + The area of the rectangle
The area of the trapezoid = 12.5 in.² + 45 in.² = 57.5 in.²

Solve the system by substitution.
x=-6y 4x + 10y = 14
Answer:
x = 6
y = -1
Step-by-step explanation:
x = - 6y ----------------------(I)
4x + 10y = 14 ------------------(II)
Substitute x = -6y in equation (II)
4*(-6y) + 10y = 14
-24y + 10y = 14 {Combine like terms}
-14y = 14 {Divide both sides by 1-4}
y = 14/-14
y = -1
Now, substitute y = -1 in equation (I)
x = - 6*(-1)
x = 6

Answer:
I am confused what the question is asking
Step-by-step explanation:
Could you please comment down below and restate the question?
Answer: ok so.. exponential function's is kinda the same process as slopes and linear equations and functions ok so........
For slopes its rise over run but for this question its...... TO BE CONTINUED LOL (go to the explanation)
Step-by-step explanation:
So for the run on the x axis its 7 you can see it goes upward a little bit on the 7 but the 7 still counts :D
ok so we got 7 and as the line rises 9go to the picture added for more understanding) So as the line rises we can see from were i marked it in the picture that it touches the 2. So we got 2 as the rise and 7 as the run but remember this is not slopes lol so its kinda different.

the straight line L passes through the points (0 , 12) and (10 , 4).
Find an equation of the straight line which is parallel to L and passes through the point (5 , -11).
Answer:
y = - [tex]\frac{4}{5}[/tex] x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 12) and (x₂, y₂ ) = (10, 4)
m = [tex]\frac{4-12}{10-0}[/tex] = [tex]\frac{-8}{10}[/tex] = - [tex]\frac{4}{5}[/tex] ← slope of line L
Parallel lines have equal slopes , then
y = - [tex]\frac{4}{5}[/tex] x + c ← is the partial equation
To find c substitute (5, - 11) into the partial equation
- 11 = - 4 + c ⇒ c = - 11 + 4 = - 7
y = - [tex]\frac{4}{5}[/tex] x - 7 ← equation of parallel line
The equation of the straight line which is parallel to L and passes through the point (5 , -11) will be;
⇒ y = - 4/5x - 7
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The straight line L passes through the points (0 , 12) and (10 , 4).
And, The equation of the straight line which is parallel to L and passes through the point (5 , -11).
Now,
Since, The straight line L passes through the points (0 , 12) and (10 , 4).
So, Equation of line L is,
⇒ y - y₁ = (y₂ - y₁) / (x₂ - x₁) (x - x₁)
⇒ y - 12 = (4 - 12) / (10 - 0) (x - 0)
⇒ y - 12 = - 8 / 10x
⇒ 10 (y - 12) = - 8x
⇒ 10y - 120 = - 8x
⇒ 10y = - 8x + 120
⇒ y = - 8/10x + 12
⇒ y = - 4/5x + 12
And, The equation of the straight line which is parallel to L and passes through the point (5 , -11).
So, We need to find the slope of the line.
Since, The slope of the parallel line is same.
Hence, Slope of the line is,
y = -4/5x + 12
m = dy/dx = - 4/5
m = - 4/5
Thus, The equation of line with slope 1- 4/5 is,
⇒ y - (-11) = - 4/5 (x - 5)
⇒ y + 11 = - 4/5 (x - 5)
⇒ 5 (y + 11) = - 4x + 20
⇒ 5y + 55 = - 4x + 20
⇒ 5y = - 4x + 20 - 55
⇒ 5y = - 4x - 35
⇒ y = - 4/5x - 7
Thus, The equation of the straight line which is parallel to L and passes through the point (5 , -11) will be;
⇒ y = - 4/5x - 7
