Please help meeee I don't know this

Vanyuwa [196]

Answer:

$\boxed {m = -\frac{5}{7}}$

Step-by-step explanation:

Use the <u>Slope Formula</u> to determine the slope of two given points:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

First Point: $(x_{1} , y_{1})$

Second Point: $(x_{2}, y_{2})$

-Substitute both points:

First Point: $(5, 11)$

Second Point: $(19, -1)$

$m = \frac{-1 - 11}{19 - 5}$

-Solve for the slope:

$m = \frac{-1 - 11}{19 - 5}$

$m = \frac{-10}{14}$

$\boxed {m = -\frac{5}{7}}$

Therefore, the slope is $-\frac{5}{7}$

Find the value of a and YZ if Y is between X and Z. XY = 7a, YZ = 5a, XZ = 6a + 24 = YZ =

Aleksandr-060686 [28]

x-y-z

$\\ \sf\longmapsto XY+YZ=XZ$

$\\ \sf\longmapsto 7a+5a=6a+24$

$\\ \sf\longmapsto 12a=6a+24$

$\\ \sf\longmapsto 12a-6a=24$

$\\ \sf\longmapsto 6a=24$

$\\ \sf\longmapsto a=\dfrac{24}{6}$

$\\ \sf\longmapsto a=5$

YZ=5a=5(5)=25

Use this expression to name each item. 7m3 + 6r2 – 3r - 8

Vitek1552 [10]

Answer:

In the given expression $7m^3 + 6r^2 - 3r - 8$

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

Step-by-step explanation:

We are given the expression $7m^3 + 6r^2 - 3r - 8$

We need to give variable, coefficients and constant.

Variable: The value of variable may change. It can be represented by x, y or any other letter

Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient

Constant: It is fixed value. It cannot be changed.

So, in the given expression $7m^3 + 6r^2 - 3r - 8$

Variables = m, r

Coefficients = 7, 6 and -3

constant= -8

What is the distance between (5, -1) and (5,-4)

jarptica [38.1K]

Answer:

Step-by-step explanation:

To evaluate for such, the following comprehension is required,

Equation Required: Distance Formula: d(P, Q) = √ (x2 − x1)^2 + (y2 − y1)^2

Denote the configurations as the following,

(5, -1). (5, -4)

X1 Y1. X2. Y2

D(P, Q) = √(5 - 5)^2 + (-4 +1)^2. <== Since the double negative is present, the operation is acknowledged as positive.

D(P, Q) = √(0)^2 + (-3)^2

D(P, Q) = √9 = 3

Thus, the agglomerate distance between the points situated in the Cartesian plane is disclosed, and is, henceforth, disseminated as 03 units.
