Answer: y = 23 x = 28
Step-by-step explanation:
First find the value of y.
The angle (5y -4) and 3y forms a straight line which means that if you add them together they will equal 180 degrees. Add them and set them equation to 180 to solve for y.
5y-4 + 3y = 180
8y -4 = 180
+4 +4
8y = 184
y= 23
Since y is equal to 23, then input y into the expression (5y-4) to find the main angle value and then add it with the angle (2x+13) to equal to 180 degrees because they also form a straight angle.
5(23) - 4
115 - 4 = 111
111 + (2x + 13) = 180
124 + 2x = 180
-124 -124
2x = 56
x = 28
x is equal to 28 degrees.
Check.
111 + 2(28) + 13 = 180
111 + 56 + 13 = 180
180 = 180

Given:
[tex]y=x^2+6x-1[/tex]
[tex]\dfrac{x}{r}=-3[/tex]
To find:
The given equation in terms of r if [tex]\dfrac{x}{r}=-3[/tex].
Solution:
Given that,
[tex]\dfrac{x}{r}=-3[/tex]
[tex]x=-3r[/tex]
We have,
[tex]y=x^2+6x-1[/tex]
Substitute x=-3r in the above equation.
[tex]y=(-3r)^2+6(-3r)-1[/tex]
[tex]y=9r^2-18r-1[/tex]
Therefore, the required equation in terms of r is [tex]y=9r^2-18r-1[/tex].
Write the equation of the line that passes through the points (4,9) and (9,1). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answers
Answer:
y=-8/5x+77/5
Step-by-step explanation:
The equation of line that passes through the points (4, 9) and (9, 1) is y=-8/5x+77/5. Hope it helps!
The equation of line passes through the points (4, 9) and (9, 1) will be;
⇒ y = - 8/5x + 77/5
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (4, 9) and (9, 1)
Now,
Since, The equation of line passes through the points (4, 9) and (9, 1)
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 9) / (9 - 4)
m = - 8 / 5
Thus, The equation of line with slope - 8/5 is,
⇒ y - 9 = - 8/5 (x - 4)
⇒ y - 9 = - 8/5x + 32/5
⇒ y = - 8/5x + 32/5 + 9
⇒ y = - 8/5x + 77/5
Therefore, The equation of line passes through the points (4, 9) and (9, 1) will be;
⇒ y = - 8/5x + 77/5

If wrapping paper comes in packages of 300 cm2. How many packages will Sally need?
Answers
Answer:
she needs 3 packages
Step-by-step explanation:
the total area of the cd is 27 cm
so like
she needs to wrap 27 cm of area
because 0.5 cm by 14 cm by 12.5 cm added all together is 27
then
27 cm equals 10.6 inches
so now we need to find how many 300cm2 will fit into that 11 inch space
There are 0.00107639 square feet in a square centimeter.
but we want to know how many feet not square feet
0.00107639 × 27 =
0.02906253
2.906253
there are 2.906253 feet per suare foot

GiveN:
-4(w + 1) = -24wWhat to do?
We have to solve for wStep-by-step explanation:
For solving the Equation, we need to simplify it first. Expanding the parentheses.
⇒ -4w - 4 = -24 w
Shifting -24 w to the LHS to isolate m and shifting 4 to the RHS[tex].[/tex]
⇒ -4w + 24w = 4
⇒ 20w = 4
Dividing the equation by 20, So that we will get w in the LHS of the equation.
⇒ w = 4/20
⇒ w = 1/5
The required value of w is 1/5.

Angle C and angle D are vertical angles with m angle C = -x + 26 and m angle D = 2x - 10.
What is m angle D?
Answers
Answer:
m∠D = 14
Step-by-step explanation:
According to the vertical angle theorem, both of these angles are congruent.
This means that they are equal (m∠C = m∠D) and we can solve for x:
m∠C = m∠D
-x + 26 = 2x - 10 (substitute in the equations)
-3x + 26 = -10 (subtract 2x from both sides)
-3x = -36 (subtract 26 from both sides)
x = 12 (divide both sides by -3)
Now that we know what x is, we can find m∠D by plugging it back into the equation:
m∠D = 2x - 10
m∠D = 2(12) - 10 (substitute the value for x in)
m∠D = 24 - 10
m∠D = 14
The value of the variable 'x' will be 12. Then the measure of the angle D will be 14°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Angle C and angle D are vertical angles with m∠C = -x + 26 and m∠D = 2x - 10.
∠C = ∠D
-x + 26 = 2x - 10
3x = 36
x = 12
Then the measure of the angle D will be
m∠D = 2x - 10
m∠D = 2(12) - 10
m∠D = 24 - 10
m∠D = 14°
The value of the variable 'x' will be 12. Then the measure of the angle D will be 14°.
