−2x+5y=−17 3x-10y=283x−10y=28

Mathematics
1 answer:
AURORKA [14]3 years ago
4 0

Answer:

x = 6

y = -1

Step-by-step explanation:

-2x + 5y = -17 ------ equation 1

3x- 10y = 28 ------- equation 2

equation 1× 2

-4x + 10y = -34 ------- equation 3

equation 2 + equation 3

-x = -6

x = 6

x = 6 substitute for equation 1

-12 + 5y = -17

5y = -5

y = -1

Line with a slope of 0 that passes through the point (6,-11)
Finger [1]

Answer: The equation of a line with a slope of 0 that passes through the point (6,-11) will be y = - 11

Step-by-step explanation:

We want to determine the equation of a line with a slope of 0 that passes through the point (6,-11)

Slope of the line = change in the value of y on the vertical axis / change in the value of x on the x axis.

Recall,

The the equation of a straight line is represented in the slope intercept form is

y = mx + c

Where

m = slope

c = intercept on the y axis

From the equation information given,

slope, m = 0

y = -11

x = 6

To get the intercept, c,

y = mx + c

-11 = 0 × x + c

-11 = c

c = -11

The equation of a line with a slope of 0 that passes through the point (6,-11) will be

y = 0x - 11

y = - 11

I don’t know how to do this I have to create a equation
Vilka [71]

Answer

Explanation

Given the word problem, we can deduce the following information:

m=0

(-2,-5)

To determine the equation of the line, we note first that the standard slope intercept form is:

y=mx+b

where:

m=slope

b=y-intercept

Since (-2,-5) is given, we plug in x=-2, y=-5 and m=0 into y=mx+b. So,

\begin{gathered} y=mx+b \\ -5=(0)(-2)+b \\ \text{Simplify and rearrange} \\ b=-5 \end{gathered}

Next, we plug in m=0 and b=-5 into y=mx+b:

\begin{gathered} y=mx+b \\ =(0)x-5 \\ \text{Simplify} \\ y=-5 \end{gathered}

Therefore, the equation of the line is:

y=-5

Tyler simplified the expression x Superscript negative 3 Baseline y Superscript negative 9. His procedure is shown below.
Dmitriy789 [7]

Answer:

D. The power y Superscript 9 should be in the numerator and the power x cubed in the denominator.

Step-by-step explanation:

The correct simplification is the following:

\frac{x^{-3}}{y^{-9}} =

= \frac{1}{x^3} \times \frac{1}{y^{-9}} =

= \frac{1}{x^3} \times y^{9} =

= \frac{y^{9}}{x^3}
