Urgent!!!!! Which equation describes the graphed line

Answers

Answer 1

Answer:

Answer: Hello, this is Bing. I can help you with your math problem.

To find the equation of the graphed line, we need to identify its slope and y-intercept. The slope is the ratio of the vertical change to the horizontal change between any two points on the line. The y-intercept is the point where the line crosses the y-axis.

Looking at the image, we can see that the line passes through the points (-3, 4) and (3, -2). We can use these points to calculate the slope:

slope = (y2 - y1) / (x2 - x1) slope = (-2 - 4) / (3 - (-3)) slope = -6 / 6 slope = -1

The slope of the line is -1. This means that for every unit increase in x, the y value decreases by 1 unit.

To find the y-intercept, we can use either of the points and plug them into the equation y = mx + b, where m is the slope and b is the y-intercept. For example, using the point (-3, 4), we have:

4 = -1 * (-3) + b 4 = 3 + b b = 1

The y-intercept of the line is 1. This means that the line crosses the y-axis at (0, 1).

Therefore, the equation of the graphed line is:

y = -x + 1

This equation matches with one of the options given below the graph: y = -1/2x + 4. This is because we can multiply both sides of the equation by 2 and get:

2y = -2x + 2 y = -1/2x + 4

Answer: The equation that describes the graphed line is y = -1/2x + 4.

What do 20-(12+6) equal

Answers

Answer:

Step-by-step explanation:

Since the 12 + 6 are parenthesis, we do these first

12 + 6 = 18

Then will solve the rest, 20 - 18

20 - 18 = 2, therefore leaving us with the answer of 2

A figure is part blue and part red.it is 5/8 red what part of the figure is blue

If $(5)/(8)$ is red, than the remaining $(3)/(8)$ would be blue. $(5)/(8)$ + $(3)/(8)$ would give you $(8)/(8)$ .

Evita lives 0.85 mile from her school . write this distance as a fraction in simplest form

Answers

Answer:

$(17)/(20)\text{ miles }$

Step-by-step explanation:

When we write a terminating decimal as a fraction,

Then we follow the below steps,

Step 1 : Write the number with denominator 1,

Step 2 : multiply numerator and denominator by an exponent of 10 ( like 10, 100, 100 etc ) to eliminate the decimal,

Step 3 : simplify the fraction by dividing both numerator and denominator by the HCF of numerator and denominator,

Here, the given number,

0.85

$=(0.85)/(1)$

$=(0.85* 100)/(100)$

$=(85)/(100)$

$=(85/ 5)/(100/ 5)$ ( HCF (85, 100) = 5 )

$=(17)/(20)$

.85 is in the hundredths place so your fraction will be 85/100 then you divide it by 5 and get 17/20 as your answer. Hope this helps

Which is equivalent to (4xy – 3z)2, and what type of special product is it?16x2y2 + 9z2, the difference of squares
16x2y2 + 9z2, a perfect square trinomial
16x2y2 – 24xyz + 9z2, the difference of squares
16x2y2 – 24xyz + 9z2, a perfect square trinomial

Answers

Answer:

$16x^2y^2-24xyz +9z^2$

Step-by-step explanation:

$(4xy - 3z)^2$

Given expression has exponent 2, so we multiply it twice

$(4xy - 3z)(4xy-3z)$

Apply FOIL method to multiply the parenthesis

multiply 4xy inside the second parenthesis

and multiply -3z inside the second parenthesis

$4xy(4xy-3z)=16x^2y^2-12xyz$

$-3z(4xy-3z)=-12xyz+9z^2$

$16x^2y^2-12xyz-12xyz+9z^2$

Combine like terms

$16x^2y^2-24xyz +9z^2$

What is the range of possible values for x?

Answers

The minimum value for 2x is 0
the maximum value is achieved when A, D and C are collinear and the quadrilateral ABCD becomes an isosceles triangle ABC
base AB = 52 and vertical angle 2x + 34°

For the sine law
(sin 2x)/22 = (sin ADB)/AB
(sin 34°)/30 = (sin BDC)/BC

is given that AB = BC, and sin ADC = sin BDC because they are supplementary, so from
(sin ADC)/AB = (sin BDC)/BC

it follows
(sin 2x)/22 = (sin 34°)/30

sin 2x = 22 (sin 34°)/30

2x = asin(22 (sin 34°)/30) ≈ 24.2°

x = 0.5 asin(22 (sin 34°)/30) ≈ 12.1°

0 < x < 12.1°
