The given point (2,5) is in the form (x,y). So x = 2 and y = 5.
Plug x = 2 into the equation given to find the predicted y value
y = 2.5x - 1.5
y = 2.5(2) - 1.5
y = 5 - 1.5
y = 3.5
We get a predicted y value of 3.5, and the actual y value is 5. Subtract the two values in this exact order
residual = (actual) - (predicted) = 5 - 3.5 = 1.5
A positive residual means that our predicted value is too small. A negative residual would be that the predicted value is too large.
Answer:
d=1.5
Step-by-step explanation:
y=2.5x-1.5 point (2,5)
f(2)=2.5(2)-1.5
f(2)=3.5 now we have two point , find the distance between them
(2,5) and (2,3.5)
d=√(x2-x1)²+(y2-y1)²
d=√(2-2)²+(3.5-5)²=
d=√1.5²=1.5
tried different way, it is 1.5

If you wrote the numbers from 1-8, and it equals to three, how do you make the statement true if you can't change the 3 but you could connect two or more numbers to make the statement true if you also can only do subtraction?
Answer:
Just add 6 to the right side of 3 which will make as 36
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36

Please help! I know its either B or D but im not sure how to tell
Answer:
D.
Step-by-step explanation:
To find the equation of g(x), we can substitute the point into each of the equations.
A. g(x) = (1/4x)^2
1 = (1/4 * 2)^2
1 = (1/2)^2
1 = 1/4
This statement is false, so this is not the equation.
B. g(x) = 1/2 * x^2
1 = 1/2 * (2)^2
1 = 1/2 * 4
1 = 2
This statement is false, so this is not the equation.
C. g(x) = 2x^2
1 = 2 * 2^2
1 = 2 * 4
1 = 8
This statement is false, so this is not the equation.
D. g(x) = (1/2x)^2.
1 = (1/2 * 2)^2
1 = 1^2
1 = 1
This statement is true, so this is your answer.
Hope this helps!

V=4
B.
Oc. v=1
V = 1/2
v=1
D.
3
.
Answer:
[tex]\frac{4}{3} \pi r^3[/tex].
Step-by-step explanation:
Let's say that the radius is r. The base diameter is two times the radius, or 2r.
Since the height is two times the diameter, the height is 2 * 2r = 4r.
The volume of a cone is 1/3 * h * pi * r^2. So, the volume of the cone is 1/3 * 4r * pi * r^2 = 1/3 * pi * 4r^3 = 4/3 * pi * r^3.
So, the volume of the cone is [tex]\frac{4}{3} \pi r^3[/tex].

A cycling race is 17 miles long. The cyclists will begin at point S and ride a number of laps around a neighborhood block. After the last lap, the cyclists will sprint 2.0 miles to the finish line. A rectangle with a width of 0.75 miles and height of 0.5 miles. The 2 mile finish comes out of one corner. Using the equation w (1.5 + 1) + 2 = 17, the race's organizer determined the cyclists will need to ride 9 laps before the sprint to the finish. Which explains the error? The equation should be 0.75 w + 0.5 w + 2 = 17, and the cyclists will need to ride 12 laps before the sprint to the finish. The equation should be 2 (0.75 w + 0.5) + 2 = 17, and the cyclists will need to ride 21 laps before the sprint to the finish. The solution should be 6, and the cyclists will need to ride 6 laps before the sprint to the finish. The solution should be 8, and the cyclists will need to ride 8 laps before the sprint to the finish.

A) 12x + y = 4
B) 9x - 3y = 11
C) 6x + 2y = 8

B.) 3.5-100
C.) 3.5-10
D.) 3.5x 10
Answer:b
Step-by-step explanation:
C and D are wrong because both of them should be divided and by 100. A is wrong because you are supposed to divide because if you multiply 3.5 x 100 its 350 and it just doesn’t make any sense because milli is smaller than deci. So by process of elimination b is the right answer.

Greetings from Brasil...
Here we don't have much to go
∛Y = A.(C + 1/X)
∛Y = (AC + A/X)
raising both members to the cube.....
(∛Y)³ = (AC + A/X)³
from Notable Products: (a + b)³ = a³ + 3a²b + 3ab² + b³
Y = (AC)³ + 3(AC)².(A/X) + 3AC(A/X)² + (A/X)³
Y = A³[C³ + (3C²/X) + (3C/X²) + (1/X³)]
variance of 147,141,120,124,128
Answer:
Variance population of 147,141,120,124,128 = 106
Variance sample of 147,141,120,124,128 = 132.5
Hope this helps and PLSSS MARK AS BRAINLIEST :)
Answer:
See below.
Step-by-step explanation:
The mean = (120+124+128+141+147) / 5
= 660 / 5
= 132
Difference between the values and the mean = -12, -8, -4, 9, 15.
Squares of these differences = 144, 64, 16, 81, 225
Sum of these squared differences = 530
So the variance = 530 / 5
= 106.
This is the population variance.
The sample variance = 530 / (5-1)
= 132.5.

Which graph shows the solution to the system of linear inequalities? 2x -3y ≤ 12 y < -3
Answer: The third graph (the one on the right side)
Step-by-step explanation:
The inequalities are:
2x -3y ≤ 12
y < -3
First, for the second inequality, we can see that y must be strictly less than -3, so we should see a dotted line at y = 3, and a shaded section under that line.
From this, we can discard the second graph (the middle one).
The first inequality can be rewritten as:
2x - 3y ≤ 12
-3y ≤ 12 - 2x
Now we divide by -3 on both sides, as we are dividing by a negative number, the direction of the ≤ sign changes:
y ≥ (12/-3) + (-2/-3)x = -4 + (2/3)*x
This means that the shaded section must be above the line:
y = -4 + (2/3)*x
Then the correct option is the third graph (rightmost graph).

Step-by-step explanation:
For the first triangle which is triangle <KJL
Hypotenuse= 8✓2
Angle=30°
Opposite = ?
Therefore we will use Sine formula
Sin30° = Y/8✓2
Y=4✓2
For the second triangle which is triangle <JML
Hypotenuse= 4✓2
Opposite=X
Angle=45°
Therefore we will use Sine formula again
Sin45°=X/4✓2
X=4
Answer:
x = 4Step-by-step explanation:
ΔJKL is half of equilateral triangle and ΔJML is half of square.
We can use properties of these triangles (picture):
m∠KJL=90° and m∠JKL = 30° ⇒ JL = 0.5KL = 0.5•8√2 = 4√2
m∠JML=90° and m∠MJL = 45° ⇒ JL = ML√2
4√2 = x√2
x = 4
Which is the solution to the equation 3.5 (2 h + 4.5) = 57.75? Round to the nearest tenth if necessary.
Answer:
h = 6
Step-by-step explanation:
Step 1: Distribute
7h + 15.75 = 57.75
Step 2: Subtract 15.75 on both sides
7h = 42
Step 3: Divide both sides by 7
h = 6

elogram ABCD, diagonals AC and BD intersect at point E. AE=2x, BE=y+10, CE=x+2 and DE=4y−8. Find the length of BD. A. 6 B. 16 C. 18 D. 32
Answer:
D
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, thus
DE = BE , substitute values
4y - 8 = y + 10 ( subtract y from both sides )
3y - 8 = 10 ( add 8 to both sides )
3y = 18 ( divide both sides by 3 )
y = 6
Thus
BD = y + 10 + 4y - 8 = 5y + 2 = 5(6) + 2 = 30 + 2 = 32 → D

Note: we're looking for two numbers that multiply to 12 and add to -7. Those two numbers are -3 and -4, so that's where the factorization (x-3)(x-4) comes in. After this step, you set each factor equal to zero and solve for x.
Answer:
x=3 x=4
Step-by-step explanation:
x^2 − 7x = −12
Add 12 to each side
x^2 - 7x +12 =0
Factor
What 2 numbers multiply to 12 and add to -7
-3*-4 = 12
-3+-4 = -7
(x-3)(x-4) =0

Explain how the distributive property helps us multiply the following polynomials and why and how the final products differ: (a + b)^2, (a – b)^2, and (a - b)(a + b).
Answer:

(a-b)^2 = a^2 - 2ab + b^2
(a-b)(a+b) = a^2 - b^2

A spinner has six spaces that are all the same size. Three spaces are yellow, two are red, and one is blue. If the spinner is spun 150 times, it should land on yellow about ___ times, on red about ___ times, and on blue ___ times.
The spinner should land on yellow about 75 times, on red about 50 times, and on blue about 25 times.
How to solve the probabilityYellow: 3 spaces out of 6, so the probability is 3/6 = 1/2
Red: 2 spaces out of 6, so the probability is 2/6 = 1/3
Blue: 1 space out of 6, so the probability is 1/6
multiplying the probability of each color by 150:
Yellow: 1/2 * 150 = 75 times
Red: 1/3 * 150 = 50 times
Blue: 1/6 * 150 = 25 times
Terefore The spinner should land on yellow about 75 times, on red about 50 times, and on blue about 25 times.
