Answer:
Option C. Side a 1.5 inches long, side b is 2 inches long and side c is 2.5 inches long
Step-by-step explanation:
The scale factor=4:1=4/1
Scale factor=(Scale drawing)/object
4/1=6/a
4a=6
a=6/4
A=1.5 inches
4/1=8/b
4b=8
b=8/4
B= 2 inches
4/1=10/c
4c=10
c=10/4
C=2.5 inches
Therefore, side a is 1.5 inches long and side b is 2 inchea long and side c is 2.5 inches long
Answer:
C
Step-by-step explanation:
with the scale factor being 4:1 (meaning shape A is bigger then shape B by 4 times) we can divide the larger shapes dimensions by 4 to get ur answer
2x2-12x +8=3 rounding to the nearest hundredth
Answer:
x=3/4 as fraction form.
x=0.75 as decimal form.
Step-by-step explanation:
Step 1.
2x2-12x+8=3
2x2=4
Step 2.
4-12x+8=3
4+8=12
12-12x=3
Step 3.
12-12x=3
(Subtract 12 from both sides.)
-12x=3-12
-12x=-9
Step 4.
-12x=-9 will equal:
0.75 or 3/4
But rounded up will equal 1 whole.
I hope this helps. :)

PLZ answer this question y-5 ≥ -15
Answer:
y (is less than or equal to) 3
Step-by-step explanation:
i hope this helps :)
The value of the inequality will be : y ≥ -10 .
Given ,
y-5 ≥ -15
Here,
y-5 ≥ -15
To solve the given inequality,
Take -5 from LHS to RHS of inequality,
y ≥ -15 + 5
y≥ -10
Thus the value of y will be equal to or greater than -10 .

solve the following equation
Answer: I think it is x= 3/74
Step-by-step explanation:
Answer:
x=3/74
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20/3x=1/2x+1/4
Step 2: Subtract 1/2x from both sides.
20/3x-1/2x=1/2x+1/4-1/2x
37/6x=1/4
Step 3: Multiply both sides by 6/37.
(6/37)*(37/6x)=(6/37)*(1/4)
x=3/74
Thus, your answer will be x=3/74.

Step-by-step explanation:
What is the slope of the line that passes through the points (5, 1) and (2, -7)?
Answer:
m [ slope ] = 8/3
Step-by-step explanation:
What is the slope of the line that passes through the points (5, 1) and (2, -7)?
m = ∆y / ∆x
m = y₂ – y₁ / x₂ – x₁
| (5, 1) → (x₁, y₁) | (2, -7) → (x₂, y₂) |
[each coordinate will correspond (directly go to) to the variables shown]
m = (-7) – (1) / (2) – (5)
m = -8 / -3
m = 8 / 3
This means that this line has a rise of 8 and a run of 3.
Up 8 and right 3 proportionally, it would touch the opposite corners of a plane that was 8 by 3 units.
Slope can be thought of as the steepness of a line, the greater the slope, the greater the steepness.
These points are generally known as cartesian coordinates.
____________
Once you have the slope, you can back track from one of the coordinates to find the equation of the line.
Just multiply the slope by the x of either coordinate, make it opposite, and then add that to the y of that coordinate to get b [the y-intercept; where it crosses the y axis, x is always 0]
Since (2, -7) is closer to the y axis than (5, 1) it is more convenient.
In (2, -7), 2 is the x variable and -7 is the y variable.
-mx + y = (-8/3)(2) + (-7) = -16/3 + (-21/3)
21/3 is the same as 7 [so it will have a common denominator].
-16 + -21 / 3 = -37/3 = b
Thus this line has an equation of
y = mx + b
↓ ↓
y = 8/3x – 37/3.
__________________________
Or you can refer to point slope which is what is taught:
y – y₁ = m(x – x₁).
You can tell that there are some similarities to this and the slope formula.
m = ( y₂ – y₁ / x₂ – x₁ ) →
m × ( x₂ – x₁ ) =
( y₂ – y₁ / x₂ – x₁ ) × ( x₂ – x₁ )
[multiply the denominator by both sides]
m ( x₂ – x₁ ) = y₂ – y₁
[x₂, and y₂ can just be x and y since you only need the initial coordinate and slope, because the second coordinate can be anything along that line]
m ( x – x₁ ) = y – y₁ →
y – y₁ = m(x – x₁)
[symmetric property of equality]
if a = b, b = a.

Answer:
f(x)=-2x^2+32x-114
Step-by-step explanation:
Answer:
f(x) = -2x^2 + 142
Step-by-step explanation:
f(x) = -2(x - 8)^2 + 14
f(x) = -2(x)^2 - (-2)(-8)^2 + 14
f(x) = -2x^2 - (-2)(64) + 14
f(x) = -2x^2 - (-128) + 14
f(x) = -2x^2 + 128 + 14
f(x) = -2x^2 + 142
