There is a line that includes the point(10, 5)and has a slope of 1 What
ziro4ka [17]

Answer:

y = x - 5

Step-by-step explanation:

Given the point, (10, 5), and the slope, m = 1:

Substitute these values into the <u>slope-intercept form</u> to solve for the y-intercept, <em>b</em>:

y = mx + b

5 = 1(10) + b

5 = 10 + b

Subtract 10 from both sides to isolate b:

5 - 10 = 10 - 10 + b

-5 = b

The y-intercept of the line is: b = -5. This represents the y-coordinate of the y-intercept, (0, -5), which represents the point on the graph where it crosses the y-axis. Along the y-axis, the value of x = 0. Hence, the y-intercept is (0, -5).  

Therefore, given the slope, m = 1, and the y-intercept, b = -5:

The equation of the line in slope-intercept form is:  y = x - 5.

Finding value of x. PQR <br> P- 2x° <br> 3<br> 3 <br> 3
Mrrafil [7]

\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the Equilateral Triangles.

Since, we know that, all the sides of a triangle are equal, hence it is a Equilateral triangle.

Equilateral triangle has one all angles equal to 60°.

so, major angle P = 60°

hence, 2x=60°

===> x = 30°

The following statement is either true​ (in all​ cases) or false​ (for at least one​ example). If​ false, construct a specific e
matrenka [14]

Answer:

False, counterexample below

Step-by-step explanation:

Denote the unit vectors of R^3 by e_1=(1,0,0), e_2=(0,1,0), e_3=(0,0,1). Now consider v_1=e_1, v_2=2e_1 and v_3=e_3. We have that v_1, v_2,v_3 \in \mathbb{R}^3. Also, the vector v_3 is not a linear combination of v_1, v_2 because any linear combination of these two vectors will have third coordinate zero, but v_3 has third coordinate 1 so they can't be equal.

However, the set \{v_1, v_2,v_3\} is not linearly independent, because 2v_1-v_2+0v_3=0 is a non-trivial linear combination of these vectors that equals zero.

PLEASE HELP ASAP WILL MARK BRAINLIEST!!
Papessa [141]

Answer:

Prime.

Step-by-step explanation:

x^2-7x+8\\

First let's multiply our outer coefficients in this case 1 and 8, so we have 1x8=8.  Now the point of this is to get the factors of 8 and see if we can get that middle term -7.  Factors of 8 are 1x8, 2x4 and that's it.  From there I notice that -8+1 = -7 and so:

x^2-7x+8 = x^2-8x+x+8 = x(x-8)+(x+8)

Notice that the (x-8) and (x+8) are not the same factors, therefore the factors are not any of those answer choices and so it's prime.  You can calculate the factors by using the quadratic formula, however I think that is beyond the scope of this question.
