Which graph represents this system? 2x-5v=-5 y=-3x+1​

Answers

Answer:

Please check the attached graph.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Given the system of equations

2x - 5y = -5    --- [Equation 1]

y = -3x + 1​      --- [Equation 2]

converting the equation 1 in the slope-intercept form

2x - 5y = -5

5y = 2x+5

divide both sides by 5

y = 2/5x + 1

Thus, the y-intercept  = 1

Now, please check the attached graph below.

The red line represents the equation  2x - 5y = -5

From the graph, it is clear that the red line has the y-intercept y = 1.

Now, considerng the equation 2

y = -3x + 1​  

comparing with the slope-intercept form of line equation

The y-intercept b = 1

Hence, the y-intercept of the line y = -3x + 1​ is y = 1

The green line represents the equation  y = -3x + 1​  

From the graph, it is clear that the green line has the y-intercept y = 1.

Point of Intersection:

It is clear from the graph:

The red line represents the equation  2x - 5y = -5.The green line represents the equation  y = -3x + 1​.

As both lines meet or intersect at the point (0, 1).

Therefore, the point of intersection of both the lines is:

(x, y) = (0, 1)

As we know that the point of intersection of both the lines represents the solution to the system of equations.

Therefore, (0, 1) on the graph represents the solution to the system of equations.

The graph is attached below.

Answer:

The slope of the line passing through (1, 2)  and (3, 8)  is:

Slope = 3

Step-by-step explanation:

Given the points

(1, 2)(3, 8)

Here:

(x₁, y₁) = (1, 2)

(x₂, y₂) = (3, 8)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [8 - 2] / [3 - 1]

               = 6 / 2

               = 3

Thus, the slope of the line passing through (1, 2)  and (3, 8)  is:

Slope = 3

Given f(x)=14(5−x)2 what is the value of f(11)?

Answers

Answer:

I was unsure about the way your question was written so I solved for two equations: f(x)=14(5-x)*2 and f(x)=14(5-x)+2

Step-by-step explanation:

Given f(x) = 14(5−x)², the value of f(11) = 504

The given function is:

f(x) = 14(5 - x)²

To get the value of f(11), substitute x = 11 into the function f(x) = 14(5 - x)²

f(11) = 14(5 - 11)²

Simplify the expression

f(11) = 14(-6)²

f(11) = 14(36)

f(11) = 504

Therefore, given f(x) = 14(5−x)², the value of f(11) = 504

Answer:  [tex](-\infty ,-0.12][/tex]

Curved parenthesis for negative infinity. Square bracket for the -0.12

========================================================

Explanation:

The inequality [tex]x \le -0.12[/tex] is the same as [tex]-\infty < x \le -0.12[/tex]

This says that x is larger than negative infinity, but smaller than or equal to -0.12

Put another way: x is between negative infinity and -0.12, x could also equal -0.12

To write this in interval notation, we would say [tex](-\infty ,-0.12][/tex]

We always use a curved parenthesis for either infinity. The square bracket indicates "include this endpoint as part of the interval".

Answer:

Step1. Slope is zeroStep2. Angles 5, 8, 9 and 12

Step-by-step explanation:

Step 1

Parallel lines have the same slope.

Gray Dr is parallel to Brodie Ln

They both are parallel to x-axis, therefore both have a zero slope.

Step 2

m∠6 = x°

Angles 5 and 8 are supplementary with angle 6, so they have a measure of (180 - x)°.

Also, since Gray Dr is parallel to Brodie Ln and Canon Rd is transversal, the angles 9 and 12 have the same measure. Because ∠6 and ∠10 are corresponding angles.

Answers

$7,425.00 this is because first you have you have to multiply 6 by 4.5%.Then that. answer (27) multiplied by 275.

The simple interest earned by Donna by the end of the sixth year is $74.24

What is simple interest?

Simple interest is the interest charge on borrowing that's calculated using an original principal amount only and an interest rate that never changes.  

Given that, Donna deposits $275 into her savings account for 6 years, the account earns 4.5% simple interest each year,

We need to find the interest earned by the end of the sixth year

Simple Interest = PRT / 100

Where,

P = Principal ($275)

R = rate (4.5%)

T = time (6 years)

SI = 275 × 6 × 4.5 / 100

= 7425 / 100

= 74.25

Hence, the simple interest earned by Donna by the end of the sixth year is $74.24

Find the length of BC, in simplest radical form.

Answers

Answer:

  BC = 16 +12√3

Step-by-step explanation:

In the attached, we see that ∆ABE is a 30°-60°-90° triangle with AB the short side and BE the hypotenuse. Then BE = 2·AB = 12√3.

EC is the side opposite AD in parallelogram ADCE, so is the same length, 16.

The length BC is ...

  BC = EC +BE
