Write an equation to represent eachrelationship. SOLVE THE EQUATION 6 less than three times a number equals eighteen.
Answer:
Equation = 3x - 6 = 18
Solving of equation =
x = 8
Step-by-step explanation:
let the number be x
Now let us first set an equation
less than means - subtraction
3x - 6 = 18
Now let us solve the equation and find the value of x
3x - 6 = 18
Transpose
3x = 18 +6
3x = 24
x = 24 ÷ 3
x = 8
Equation = 3x - 6 = 18
Solving of equation =
x = 8
A line passes through the points (-2,-4) and (3, 5). Which equation best represents a line
parallel to this line?
A) y = -5/9x+ 4
B) y = 9/5x + 4
C) y = 1x + 4
D) y = -4/3x + 4
The equation best represents a line parallel to the given line is y = 9/5x - 2/15.
What is the equation of line?The general equation of a straight line is
y = mx + c,
where m is the gradient, and y = c is the value where the line cuts the y-axis.
This number c is called the intercept on the y-axis.
Now it is given that the line passes through (-2,-4) and (3,5).
So here,
x1 = -2;
y1 = -4;
x2 = 3;
y2 = 5
Hence slope of the line is given as,
m1 = (y2 - y1)/(x2 - x1)
⇒ m1 = {5-(-4)}/{3-(-2)}
⇒ m1 = (5+4)/(3+2)
⇒ m1 = 9/5
Since both the lines are parallel, hence
m1 = m2 = 9/5
Therefore equation of line parallel to the given line will be,
(y - y1) = m2( x - x1)
⇒ {y-(-4)} = 9/5{x - (-2)}
⇒ y + 4 = 9/5(x +2)
⇒ y + 4 = 9/5x + 18/5
⇒ y = 9/5x + 18/5 - 4
⇒ y = 9/5x - 2/15
Hence, The equation best represents a line parallel to the given line is y = 9/5x - 2/15.

Find the missing angle measures.
Y = 63
Z = ?
X = ?
Answer:
Step-by-step explanation:
y = 63 {Vertical angles are congruent}
y + z + 85 = 180 {Angle sum property of triangle}
36 + z + 85 = 180
z + 121 = 180
z = 180 - 121
z = 59
63 + x = 130 {External angle property of triangle}
x = 130 - 63
x = 67

find all of the zeros of
If f(x) = x3 + 13x2 + 32x + 20 and f(-10)=0
pls help with this problem !
Answer:
Step-by-step explanation:
Well you have one of the roots -- -10. Just by looking at it, -1 would seem to be another x intercept.
f(x) = (-1)^3 + 13(-1)^2 + 32(-1) + 20
f(x) = -1 + 13 - 32 + 20
f(x) = 0
So - 1 is also a root.
You should try -2
-2 * -10 - 1 = - 20
f(-2) = (-2)^3 + 13(-2)^2 + 32(-2) + 20
f(-2) = -8 + 13 * 4 - 32(2) + 20
f(-2) = - 8 + 52 - 64 + 20
f(-2) = -72 + 72
f(-2) = 0
The zeros are
x = -10
x = -1
x = -2

Answer:
1/20 is the correct answer
Step-by-step explanation:
65/100 diet
30/100 caffeine
Of the 65/100, 22 are caffeine free but that is unnecessary info for the question. The 22 caffeine free would fall under the 65/100 anyways.
So 65 + 30 = 95
100-95 = 5
5/100 simplified is 1/20
Yes, you are correct . Since we know 65 sodas are diet and 30 are caffeine-free.
65 + 30 = 95
What plus 95 equals 100?
95 + x = 100
Or 100 - 95 = 5
= 5/100
When 5/100 is simplified, it equals 1/20.

what does x equal in the equation
-4(x-1) + 6x = 2(17-x)
Step-by-step explanation:
since -4(x-1) + 6x = 2(17-x) [expand the bracket]
⇒ -4x +4 + 6x = 34 - 2x [group like terms across the equal sign]
⇒ -4x + 2x + 6x = 34 - 4 [simplify like terms]
⇒ 4x = 30 [divide both sides by 4]
⇒ x = ³⁰/₄ [simplify RHS to lowest possible fraction]
⇒ x = ¹⁵/₂Check:
-4((¹⁵/₂) - 1) + 6(¹⁵/₂) = 2(17-(¹⁵/₂))

A number x is no less than -42
Step-by-step explanation:
It mean more than -42 or equal to -42
please give me a brainliest answer
The inequality that represents the statement "A number x is no less than -42" is x ≥ -42.
The inequality that represents the statement "A number x is no less than -42" can be expressed as:
x ≥ -42
In this inequality, the symbol "≥" stands for "greater than or equal to." It indicates that "x" can take any value that is equal to -42 or any value greater than -42. If "x" equals -42, the condition is satisfied, and if "x" is greater than -42, the condition is also satisfied.
For instance, if "x" is -40, the inequality holds true, as -40 is greater than -42. Similarly, if "x" is 0 or any positive number, the inequality remains true, as all these values are greater than -42.

All I know is that it is acute and less than 51 degrees
Answer:
AOB is 39 degrees.
Step-by-step explanation:
Given that ∠DOE is 51 degrees we know that ∠AOE is 180 degrees as it is a straight line.
∠BOD is a right angle given the ∟symbol so therefore ∠BOD is equal to 90 degrees.
m∠DOE + m∠BOD = 141 degrees (because 51 + 90)
Therefore m∠AOB = 39 because 180 - 141 = 39
Straight angles are equal to 180! Hope this helped
