Solve for the values of x:
(2x-1)(x+4) = 0
Step-by-step explanation:
x = -4, 1/2 is the value of x
The values of x that satisfy the equation (2x - 1)(x + 4) = 0 are
x = 1/2 and x = -4.
Here, we have,
To solve for the values of x in the equation (2x - 1)(x + 4) = 0, we can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero.
So, we set each factor equal to zero and solve for x:
2x - 1 = 0
Adding 1 to both sides:
2x = 1
Dividing both sides by 2:
x = 1/2
x + 4 = 0
Subtracting 4 from both sides:
x = -4
Therefore, the values of x that satisfy the equation (2x - 1)(x + 4) = 0 are x = 1/2 and x = -4.

Answer:
77 degrees.
Step-by-step explanation:
All triangles equal up to a measure of 180 degrees.
If one side is 26 degrees, and the other sides are congruent, meaning the same, then:
1. 180-26 = 154
2. 154/2 = 77
The measures of the other sides are 77 degrees.

A unit rate is a special kind of ratio, where the second number, or the denominator, is equal to one. With a unit rate, you are comparing a quantity to one. Some common unit rates are miles per gallon, price per pound, and pay rate per hour. ... Next, divide the price by the pounds so you can find the unit rate.

Lines AB and CD are parallel. Find the measures of the three angles in triangle ABF.
What is the angle measurement for A, B, and F. (Make sure they are degrees)
Can you help me with this math question?
A = 42°
B= 23°
F = 115°
Step-by-step explanation:
The required measures of the three angles in triangle ABF are A = 23°, B = 42°, and F = 115°.
What are Alternate Interior Angles?Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines
Given that Lines AB and CD are parallel.
To determine the measures of the three angles in triangle ABF.
For finding ∠F,
∠CDF = 180° - 157° = 23°
∠F = 180° - ∠C - ∠CDF
∠F = 180° - 42° - 23°
∠F = 115°
However, if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.
So ∠A = ∠CDF = 23°
And ∠B = ∠C = 42°
Thus, the required measures of the three angles in triangle ABF are A = 23°, B = 42°, and F = 115°.

pls help with geometry!! will mark brainliest
Answer:
x = 6°
y = 15°
Step-by-step explanation:
90 + 6y = 180 (linear pair, supplementary)
6y = 90 (180 - 90)
y = 15°
6y and 5x + 60 are corresponding angles. Corresponding angles are equal
Hence:
6y = 5x + 60
Sub y = 15° into equation
90 = 5x + 60
90 - 60 = 5x
5x = 30
x = 6°

Step-by-step explanation:
i will use the last one as an example, first reduce, so you would find the common denominator, in this case its 6, so you simplify 6/30 to 1/5. then you have 4/5+1/5, so since u have the same denominator, you can add the two numerators above the common denominator, so it would look like 4+1/5. then add the numbers. so you are left with 5/5 which in other words is 1. i hope this helps!

A young sumo wrestler decided to go on a special high − -protein diet to gain weight rapidly. After 1 1 11 months, he weighed 1 4 0 k i l o g r a m s . 140 kilograms. He gained weight at a rate of 5 . 5 k i l o g r a m s 5.5 kilograms per month. Let y y represent the sumo wrestlers weight ( i n k i l o g r a m s ) (in kilograms) after x months. Whats the y-intercept?
Given:
After 11 months, sumo wrestler weighed 140 kilograms.
He gained weight at a rate of 5.5 kilograms per month.
To find:
The y-intercept of the equation which represents y the sumo wrestlers weight (in kilograms) after x months.
Solution:
Let y represent the sumo wrestlers weight (in kilograms) after x months.
It is given that he gained weight at a rate of 5.5 kilograms per month.
So, slope of the line is 5.5.
After 11 months, sumo wrestler weighed 140 kilograms. It means the line passes through the point (11,140).
The point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope of the line.
[tex]y-140=5.5(x-11)[/tex]
[tex]y-140=5.5x-60.5[/tex]
Add 140 on both sides.
[tex]y-140+140=5.5x-60.5+140[/tex]
[tex]y=5.5x+79.5[/tex]
Therefore, the required equation is [tex]y=5.5x+79.5[/tex].
Substitute x=0, to find the y-intercept of this equation.
[tex]y=5.5(0)+79.5[/tex]
[tex]y=79.5[/tex]
Therefore, the y-intercept is 79.5. It means initial weight of sumo is 79.5 kilograms.

Using the graph, determine the coordinate of the y-intercept of the parabola.
Answer:
(0,8)
Step-by-step explanation:
The parabola intercepts at 8 on the y axis, and since the interception has zero x value, x=0.
The graph the coordinate of the y-intercept of the parabola is (0, 8).
What is Intercept?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilise the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.
Given:
From the parabolic graph we can see that the intersecting point (0, 8)
Now, the y- intercept is the point in the vertical axis.
As, from the graph the coordinate of the y-intercept of the parabola is (0, 8)
