Answer:

4x+y=17 that the answer  

Step-by-step explanation:

Answer:

-4x-17=y

Step-by-step explanation:

Distribute the -4 into the parenthises. Then subrtract the 1 from both sides.

The equation should be [tex]y = 2\div 5x + 2[/tex]

Given that,

Based on the above information, the calculation is as follows:

here we need to find the slope.

[tex]= (y_2-y_1)\div (x_2-x_1)\\\\= (0-4)\div (-5-5) \\\\= -4\div -10 \\\\= 2\div 5\\\\Y = 2\div 5x + b[/tex]

Now  

Put in one point

[tex]4 = 2\div 5(5) + b, b = 2[/tex]

So,

[tex]y = 2\div 5x + 2[/tex]

Answer:

All but the second one

Step-by-step explanation:

Find the inverse of each function:

b(x)=x^2+3

y=x^2+3

x=y^2+3

x-3=y^2

sqrt(x-3)=y

This inverse function is a function

d(x)=-9

y=-9

This doesn't have an inverse function

m(x)=-7x

y=-7x

x=-7y

-1/7x=y

This inverse function is a function

p(x)=|x|

y=|x|

x=|y|

x=y

This inverse function is a function

Therefore, all but the second function have inverses that are functions

y=-f(x)-3

Step-by-step explanation:

when f is negative it is reflected over the x-axis and -3 means to translate 3 units down

y = -f(x) – 3 describes the graphed function.

When f is negative it is reflected over the x-axis.

-3 means to translate 3 units down.

Answer:

4 bottles of Water

Step-by-step explanation:

First, we need to find how much each water costs. So, I created this equation below.

9/12=?

The answer to the equation is .75, or 75 cents.

So, we can now make yet another equation to find the amount to buy with 3 dollars.

3/.75=?

The answer to that equation is 4.

Thus, the answer is 4 bottles of water.

The cost of 9/16 pounds of tea is $13.50.

In order to determine the cost of 9/16 pounds of tea, the cost of a pound of tea would be multiplied by 9/16 pounds.

Cost of 9/16 pounds of tea = 9/16 x 24

= $216/16

= $13.50

Answer:

y= -7x+7

Step-by-step explanation:

y= mx+b

y= slope x+ y intercept

The equation of the line having the slope -7 and y-intercept  is 7 is: y = -7x + 7

A straight line's equation is a relationship between its x and y coordinates, and it is written as y = mx + c, where m is the line's slope and c is its y-intercept.

We are given that the slope m is -7,

and the line crosses the y-axis at 7.

so the value of c = 7

Therefore, we can substitute these values into the slope-intercept form to get:

y = -7x + 7

So the equation of the line is y = -7x + 7.

Answer:   1.50+5m=76.50 m=15

Step-by-step explanation:

The required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

pick-up fee = $1.50 plus $5 per mile

Since, m is the number of miles in the taxi ride

So, equation for pick-up fee for m miles,

pick-up fee = $1.50 + $5m

Now total fare = $76,50

Thus, required equation to determine m is given as,

1.50 + 5m = 76.50

Subtracting 1.5 both the side we get,

1.50 + 5m - 1.5 = 76.50 - 1.5

⇒ 5m = 75

or, m = 75/5

⇒ m = 15

Thus, the required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

Answer:

Step-by-step explanation:

to find x we can use tangent function

tan 31= x/9

0.60=x/9

x=0.60*9=5.4 choice B

The measure of x side.

We have given a right angle triangle whose angle A=31 degrees and two sides that is x and 9.

We have to determine the value of x.

Therefore we use here the trigonometric ratio

[tex]tan\theta=\frac{opposite side}{adjacent side}[/tex]

Therefore we get

tan 31= x/9

tan(31)=0.60

0.60=x/9

Isolate the x

x=0.60*9

x=5.4

Therefore option B is correct.

Answer:

D) 4/3 x + 4

Step-by-step explanation:

The y-intercept is at point (0, 4) and the x--intercept is at point (-3, 0).

The equation for every straight line is y = mx + b. y is y, m is the slope, x is x, and b is the y value in the y-intercept

Now we will use the formula for slope, which is rise/run or more understandable , the change in y/change in x.

y2 - y1/x2 -x1

0 - 4/-3 - 0

-4/-3 = 4/3

Remember when I said the y-intercept was (0, 4) and b was the value of the y in the y-intercept? 4 is the value of y in the y-intercept.

The answer is 4/3x + 4.

Long arc QR is twice the measure of inscribed angle QSR, so is 2×95° = 190°. That, together with the remaining short arcs ? and RS will make up the total circle of 360°.

  arc QR + arc RS + ? = 360°
