Answer:

-7

Step-by-step explanation:

Since we have 2 points, we can use the slope formula

m = ( y2-y1) /(x2-x1)

= ( 8-1)/( -7 - -6)

= ( 8-1) / ( -7+6)

= 7/ -1

= -7

Hello!

Slope formula:

y2-y1/x2-x1

y2: 8

y1: 1

x2: -7

x1: -6

Plug given values into the equation:

8-1/-7 - (-6)

Subtract

7/-1

Divide

-7

The slope is -7

If ethans monthly expenses are 1160 and his debt to income ratio is 0.8 what is his monthly salary

lukranit [14]

Answer:

$1450$

Step-by-step explanation:

Based on the given conditions, formulate: $\frac{1160}{0.8}$

Convert decimal to fraction: $\dfrac{1160} {\dfrac{8}{10}}$

Divide a fraction by multiplying its reciprocal: $1160 \times \dfrac{10}{8}$

Cross out the common factor: $145 \times 10$

Calculate the product or quotient: $1450$

get the result: $1450$

Answer: $1450$

What is the value of x?

antoniya [11.8K]

Since the figure is a rhombus, the diagonals cut each other at right-angles and bisect each other, namely cut their vertices in equal halves.

what the dickens does all that mean? well, the angles at vertex C and vertex A are all twins, and therefore, ∡BCA = x, therefore

$\bf (3x-26)+(x)+(90)=180\implies 4x+64=180\implies 4x=116
\\\\\\
x=\cfrac{116}{4}\implies x=29$

Can someone please explain to me how to solve a problem like:

Nadya [2.5K]

27x + 9
------------
3

Break down the fraction. 3 is the common denominator, so it is the denominator of both numerators.

27x/3 + 9/3 = 0
9x + 3 = 0
9x = -3
x = -3/9 simplified to x = -1/3

Or simply multiply the fraction with 3/1 to remove the denominator, which is 3.

27x + 9 3 27x + 9
----------- x ------- = ----------------- or 27x + 9 = 0 ; look for x.
3 1 1

To check: Substitute x by its value:
(27x + 9) / 3 = 0 ⇒ ((27 * -1/3) + 9) / 3 = 0
⇒ (-9 + 9)/3 = 0 ⇒ 0/3 = 0 ⇒ 0 = 0

Find the nonpermissible replacement for a in this expression 6/-5a

Mademuasel [1]

Find the nonpermissible replacement for a in this expression 6/-5a

Denominator cannot be zero or else undefined so set the denominator to zero and solve for the a that will cause the denominator to be zero.
-5a=0
-5/-5x=0/-5
x=0

Nonpermissable replacement is 0.
