Answer:

-4.1

Step-by-step explanation:

Answer:

-17 - 13.9 = -30.9

Step-by-step explanation:

when subtracting negative and positive numbers you get a negative:

- -  +  =  -

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:

(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).

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)

Answer: -7/11

Step-by-step explanation:

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.

Use the given functions to set up and simplify

7B.4=f(1)=2=Always(true)n=Always(true)1A⋅1=A3=A5=A7B=A

Step-by-step explanation:

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°.

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°.

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:

Answer:

50

Step-by-step explanation:

180 - 65 = 115----> 115 - 65 = 50

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°
