Which of the equations are true identities? \begin{aligned} \text{A. }&(y+6)(y-7)+42=y^2-y \\\\ \text{B. }&(x+3)(x-8)=x^2-5x \end{aligned} A. B. (y+6)(y−7)+42=y 2 −y (x+3)(x−8)=x 2 −5x
Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.

A bakery has 36 glazed donuts on display. This is 80% of the total number of donuts. What is the total number of donuts in the bakery?
Answer:
it is 64.8, but you have to round to the nearest number, so i would say 65 :)
Step-by-step explanation:
Answer:
45
Step-by-step explanation:
% means out of 100, so 80% is 80/100
Let's divide 100/80 to find a scale we can use to multiply 36, 100/80 =
36 times 1.25 = 45
There's 45 donuts
Double check:
45(80/100) = 36, we're right

Answer:
D
Step-by-step explanation:
The equation of the line that passes through the point begin ordered pair, negative 6, 1, end ordered pair and has a slope of begin fraction . . . negative 1 over 2 . . . end fraction is y=-1/2x-2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Slope is -1/2
Using point-slope form, the equation of the line can be written as:
y - y₁ = m(x - x₁)
Substituting the values given in the problem, we get:
y - 1 = (-1/2)(x - (-6))
y-1=-1/2(x+6)
y-1 = -1/2x -3
y=-1/2x-2
Hence, the equation of the line that passes through the point begin ordered pair, negative 6, 1, end ordered pair and has a slope of begin fraction . . . negative 1 over 2 . . . end fraction is y=-1/2x-2.

5/3y=-(x-5) in slope intercept form
Required slope intercept form is [tex]y = - \frac{3}{5} x + 3[/tex]
What is slope ?
The slope of a line is a measure of the steepness and direction of the line. Finding the slope of lines in a coordinate plane can help predict whether the lines are parallel, perpendicular, or missing without using a compass.
The slope of any straight line can be calculated using two points on the line. The slope of the line formula calculates the ratio of "vertical change" to "horizontal change" between two different points on the line. In this article we will understand the slope finding method and its applications.
The slope of a line is defined as the change in the y-coordinate relative to the change in the x-coordinate of that line. The net change in the y-coordinate is Δy, while the net change in the x-coordinate is Δx. Thus, the change in the y-coordinate with respect to the change in the x-coordinate can be written as: m = Δy/Δx
Here given,Equation of line [tex] \frac{5}{3}y = - (x - 5)[/tex]
We want to find what is 5/3y=-(x-5) in slope intercept form ?
We want to simplify the equation.
[tex]5y = - 3(x - 5) \\ 5y = - 3x + 15 \\ y = \frac{ - 3x + 15}{5} \\ y = - \frac{3}{5} x + \frac{15}{5} \\ y = - \frac{3}{5} x + 3....(1)[/tex]
We know slope in line y = mx+c is m.
We are comparing equation (1) with y = mx + c and get [tex]m = - \frac{3}{5} [/tex]
Equation (1) is slope intercept form of 5/3y=-(x-5).
Therefore,required slope intercept form is [tex]y = - \frac{3}{5} x + 3[/tex]

Lucinda lives .6 miles from the park. Angie lives 10 times as far from the city park as Lucinda. Stacy lives 1/10 of a mile further from the park than Angie. However, she lives 3/10 of a mile closer to the park than Gabriel. How far from the park does Gabriel live?
Answer: 6.4 miles
Step-by-step explanation:
Lucinda lives 0.6 miles from the Park and Angie lives 10 times as far as this.
= 0.6 * 10
= 6 miles
Stacy lives 1/10 miles further than Angie;
= 6 + 1/10
= 6.1 miles
She lives 3/10 of a mile closer than Gabriel which means that Gabriel lives 3/10 of a mile further from the park than Lucinda;
= 6.1 + 3/10
= 6.4 miles
Divide 6 divided by 3/5

If Triangle ABC ≈ Triangle DBE, find the value of x.
Answer:
x = 49
Step-by-step explanation:
The sum of angles in a triangle add up to 180°.
∠CBA = ∠EBD (Vertically opposite angles are equal)
= 52°
Since in the triangle DBE, you already know two of the angles, you can find ∠BDE which is equal to ∠CAB (x + 9)°.
∠BDE = 180° - 70° - 52°
= 58°
∠BDE = ∠CAB
= ∠(x + 9)°
= 58°
x + 9 = 58
x = 58 - 9
x = 49

The length of a room is 4 feet less than twice its width. The perimeter of the room is 58 feet. What is the length of the room?
Answer:
Length = 18
Step-by-step explanation:
Length= 2w - 4
Perimeter= 58
Perimeter= 2L + 2w
58 = 2(2w-4) + 2w
58 = 4w -8 + 2w
58 = 6w - 8
66 = 6w
11 = w
Plug in width to find the variable L
58 = 2L + 2(11)
58 = 2L + 22
36 = 2L
18 = L
