Let the missing value = x
Slope is the change in y over the change in x:
3 = (x-2)/ (8-3)
3 = (x-2) / 5
Multiply both sides by 5:
15 = x-2
Add 2 to both sides:
X = 17
The missing coordinate is 17

3(x-5) – 1/2(10x + 10) I don’t understand and I need the answers
Answer:3x-15-5x-5
-2x-20
Step-by-step explanation:
Answer:
-2x-20
Step-by-step explanation:
Expand 3(x-5) : 3x-15
Do not forget there is a subtraction sign in the middle.
Expand 1/2(10x+10) : 5x+5 : 5(x+1)
= 3x - 15 - 5(x+1)
Expand -5(x+1) : -5x-5
= 3x-15 - 5x - 5
Simplify 3x-15-5x-5 by adding like terms: -2x-20
= -2x-20
The sum of two numbers is 82. One number is three less than four times the other. Find the two numbers.
Answer:
17 , 65
Step-by-step explanation:
x+ y = 82
y = 4x - 3
=====================
Put the second equation into the first.
x + 4x - 3 = 82
5x = 85
x = 85/5
x = 17
17 + y = 82
x = 82 - 17
x = 65

Quadrilateral EFGH is a scaled copy of quadrilateral ABCD. Select ALL of the true statements.
Segment EF is twice as long as segment AB.
True/false
B. Segment CD is twice as long as segment FG.
True/false
C. The measure of angle HEF is twice the measure of angle DAB.
True/false
D. The length of segment EH is 16 units.
True/false
E. The measure of angle BCD is the same as the measure of angle GFE.
True/false
Answer: True, False, False, True, False
Step-by-step explanation:
Since the two quadrilaterals are similar, for question A your answer of True is correct since EF would scale to be twice as long as AB. For the second question the reverse logic applies. For Question C EH is 16 units since 8x2 is 16. For the last question, since BCD does not corresponds to GFE, it is false. Angle BCD has a vertex at point C and GFE has a vertex at point F. Since C does not correspond to F, the angles are not the same.

What is the value of x, when -25(x - 4) = -55(x - 10)?
Answer:
-25(x - 4) = -55(x - 10)
-25x+100= -55x+550
-25x+55x=550-100
30x=450
x=15
Answer:
x= 15
Step-by-step explanation:
Step 1- Distribute into the parenthesis
-25x-(-25)4= -55x-(-55)10
Step 2- Multiply to simplify
-25x+100= -55x+550
Step 3- Add -55x to both sides
-25x+100= -55x+550
+55x +55x
Step 4- Subtract 100 to both sides
30x+100= 550
-100 -100
Step 5- Divide both sides by 30
30x= 450
30 30
x= 15
What is the domain and range for y=x3 – 4x² + x + 6
Answer:
Domain: set of Real numbers
Range{ set of Real numbers
Step-by-step explanation:
Since this is a cubic function, its domain and range are both the set of Real numbers.
The domain of any polynomial function is the set of Real numbers, And as far as the Range, we decide based on its end-behavior: since this is a polynomial with leading term [tex]x^3[/tex], then it has the property of getting to infinitely large values for increasing values of x, and infinitely negative values for decreasing values of x.
HELPPPP PLEASE !!! I do not get this someone help
Answer:
20
Step-by-step explanation
not sure but looks like you need help as fast as possible here my answer the way i thought about is you have 70 degree angle and y looks like a right angle which = 90 degree
x = 180 - 70+90
x = 180 - 160
x = 20
The value of the angle x for the given triangle will be 20°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
As per the given triangle,
m∠y = 90°
The exterior angle = sum of two interior angles except for the adjacent angle of the exterior angle.
110° = x + y
110° = x + 90°
m∠x = 20°
Hence "The value of the angle x for the given triangle will be 20°".

how many fourths are in one third?
Answer:
there is one fourth in one third
Step-by-step explanation:
1/3 < 1/2
one third is less than two fourths (one half)
1/3 > 1/4
but it is more than one fourth, so one fourth fits in one third.

Can somebody help me out on this question I would really appreciate it so much . Please and thank you .
Step-by-step explanation:
AB = AC, so mark the two sides with single tick marks.
m∠ACD = 128°, so label the angle 128°.
∠ACB is supplementary to ∠ACD, so:
m∠ACB + m∠ACD = 180°
m∠ACB + 128° = 180°
m∠ACB = 52°
ΔABC is an isosceles triangle, so m∠B = m∠ACB.
m∠B = m∠ACB
m∠B = 52°
Angles of a triangle add up to 180°, so:
m∠A + m∠B + m∠ACB = 180°
m∠A + 52° + 52° = 180°
m∠A = 76°

The quotient of a number and 17 is 118.82.
A. it can be solved with division property of equality.
B. It can be solved with the multiplication property of equality
C. The equation should x/17=118.82
D.x=7
E. X=2020
Answer:
C. The equation should x/17=118.82
Step-by-step explanation:
We know that
Dividend ÷ Divisor = Quotient
Dividend/Divisor = Quotient
From the question, we are told that:
The quotient of a number and 17 is 118.82
Let us represent the unknown number as x = Dividend
17 = Divisor
Quotient = 118.82
Hence,
x / 17 = 118.82
Cross Multiply
x = 17 × 118.82
x = 2019.94
The correct answer = Option C. The equation should x/17=118.82

7. Identify the explicit formula for the sequence given by the recursive formula
Answer: B) f(n) = 30 - 8(n - 1)
Step-by-step explanation:
Explicit formula is of the form: [tex]a_n=a_1+d(n-1)[/tex] where
[tex]a_1[/tex] is the first term d is the difference between consecutive termsGiven: f(1) = 30 --> this represents the first term [tex]a_1[/tex] = 30
f(n - 1) - 8 --> this means the previous term minus 8 thus d = -8
[tex]a_n[/tex] = 30 + (-8)(n - 1)
= 30 - 8(n - 1)

If UV=5x, VW = 8x - 17, and UW = 11x+11, what is UW
Answer:
UW=165
Step-by-step explanation:
UV + VW =UW
5x + 8x-17= 11x +11
13x - 17 = 11x + 11
Subtract 11x and add 17 to both sides:
2x= 28
Divide 2 both sides:
x=14
Plug in x to the equation of UW:
11 (14) +11
165
