Write an equation for each line in slope-intercept form.

Answers

Answer:

y = x + 7

Step-by-step explanation:

The slope-intercept form of a line is:

y = mx + b

where m is the slope and b is the y-intercept.

Looking at the graph, we can see that the line intersects the y-axis at y = 7. So 7 would be our y-intercept.

To find the slope, we would divide the rise of the line by the run. Or m = rise/run. From looking at the graph, we can see that for every 1 unit the line moves in the x-direction, the line moves in the y-direction by 1 unit. Therefore, the rise would be 1 and the run would be 1. 1/1 = 1 so the slope of the line would be 1.

Plugging in 7 for b and 1 for m into the equation for the slope-intercept form, we get:

y = x + 7

So that would be the equation for the line in slope-intercept form.

Answer:

Therefore, the y-intercept is (0,2.5) and x-intercept is (3.5,0) .

Step-by-step explanation:

Intercept means the line touching the axis. As you look at the graph, y-intercept (line touching y-axis) is (0,2.5) and the x-intercept is (3.5,0) .

Take note :

When finding y-intercept, x-coordinate must be 0.

Sultan measures the distance he drives to work each day using the odometer on his car, which measures distance in


miles, accurate to the nearest tenth of a mile. If the odometer reads 11.7 miles, what between what two quantities can


you be certain that the exact distance lies?


in two or more complete gfsentences, explain your reasoning,

Answers

Answer:

We can be sure that the actual distance lies between 11.65 and 11.74

Step-by-step explanation:

Here. we are told that the odometer measures to the nearest tenth.

The nearest tenth means to the nearest first digit after the decimal point

So the range of values we shall be writing will be the range that includes the smallest number that can be approximated to 11.7 and the largest number that can be approximated;

Thus, we have;

11.65 to 11.74

The reasoning is because the smallest number that can be approximated to 11.70 is 11.65 while the largest that can be approximated to 11.70 is 11.74. So the actual distance we need from the odometer is between 11.65 and 11.74

Correct answer is: Alternate Exterior Angles Theorem

Step-by-step explanation:

See attached picture.

The angles ∠1≅∠11 are equal by alternate exterior angles theorem and corresponding angles postulate. The correct options are A and D.

What is an alternate exterior angle?

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

According to the alternate outside angle theorem, alternate exterior angles are regarded as congruent angles or angles of equal measure when two parallel lines are intersected by a transversal.

In the given image there are two parallel lines and one line is intersecting the two parallel lines at some angle.

Angle 1 and angle 11 will be equal to each other because of the two properties of angles that are alternate exterior angles theorem and corresponding angles postulate.

Therefore, the angles ∠1≅∠11 are equal by alternate exterior angles theorem and corresponding angles postulate. The correct options are A and D.

What is the slope of a line perpendicular to the line whose equation is
15x + 12y = -144. Fully reduce your answer.

Answers

Step-by-step explanation:

Hey there!

Let the unknown slope be M2.

The given equation is;

15x + 12y = -144

From equation;

[tex]slope( m) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]

[tex]m = \frac{ - 15}{12} [/tex]

[tex]m = \frac{ - 5}{4} [/tex]

For the condition of perpendicular lines;

[tex]m \times m2 = - 1[/tex]

[tex] \frac{ - 5}{4} \times m2 = - 1[/tex]

[tex] - 5m2 = - 4[/tex]

[tex]m2 = \frac{ - 4}{ - 5} [/tex]

Therefore, the slope is 4/5.

All right triangles are similar. C. Both triangles are right and scalene. OD The Pythagorean theorem states that a + b = c2. Thus, the corresponding sides are proportional. Find the missing length 2 X= m​

Answers

Answer:

A. Both triangles contain right angles and a corresponding angle of equal measure. Thus, two angles of the large triangle are equal in measure to two angles of the small triangle

x = 3 m

Step-by-step explanation:

The figure given shows two right angles triangles having corresponding angles that are congruent and of the same measure.

If we find the ratios of their given corresponding side lengths, their ratios would be the same.

Thus: ratio of the side of the smaller ∆ to the larger ∆ = 4:8 = 5:10 = 4/8 = 5/10 = ½

½ is the scale factor. Therefore, both triangles are similar.

To find x, multiply the corresponding side length of the other triangle by the scale factor.

x corresponds to side length that is 6 m in the other triangle.

Therefore,

x = 6*½ = 3 m

The value of 'x' in the smaller triangle is 2 and both the triangles are similar because triangles contain right angles and a corresponding angle of equal measure. Therefore, two angles of the large triangle are equal in measure to two angles of the small triangle.

Given :

Two triangles are given in the figure.

The Pythagorean theorem can be used in order to determine the value of 'x' in the smaller triangle.

[tex]5^2=4^2+x^2[/tex]

[tex]x^2= 25-16[/tex]

x = 3

According to the given figure of the triangles, both triangles contain right angles and a corresponding angle of equal measure. Therefore, two angles of the large triangle are equal in measure to two angles of the small triangle. Hence both the triangles are similar.

Therefore, the correct option is A).
