Answers

Answer 1

9514 1404 393

Answer:

road bike: $650mountain bike: $700

Step-by-step explanation:

If r is the cost of a road bike, then the cost of a mountain bike is r+50. The total cost of the 7 bicycles is ...

  4r +3(r+50) = 4700

  7r +150 = 4700 . . . . . . eliminate parentheses

  7r = 4550 . . . . . . . . . . . subtract 150

  r = 650 . . . . . . . . . . . . . divide by 7; price of a road bike

  r+50 = 700 . . . . price of a mountain bike

The price of a road bike is $650; the price of a mountain bike is $700.

Answer:

y [tex]\geq[/tex] 3x + 3

y < -x - 2

Step-by-step explanation:

For the first one, you can see that the slope is 3 and the y-intercept is 3, so the equation of the line would be y = 3x + 3. Then, since the shaded area is above the line it would be greater than and since the line isn't dashed it is greater than or equal to.

The completed equation is y [tex]\geq[/tex] 3x + 3

For the second one, you can see that the slope is -1 and the y intercept is -2, so the equation of the line would be y = -x - 2. Then, since the shaded area is below the line and the line is dashed, the completed equation is y < -x -2

(I really need help) FGHIJ ~ YUVWX. Find UY and GH.

Answers

Answer:

UY = 90

GH = 4

Step-by-step explanation:

Given that FGHIJ ~ YUVWX, therefore, their corresponding side lengths would be proportional to each other. Thus:

UY/GF = VW/HI

UY/10 = 63/7 (Substitution)

UY/10 = 9

UY = 10*9

UY = 90

In the same vein, we have:

VW/HI = UV/GH

63/7 = 36/GH (Substitution)

9 = 36/GH

GH*9 = 36

GH = 36/9

GH = 4

Solve the Equation. 14x+28=14

Answers

Answer:

x= -1

Step-by-step explanation:

1. First, you need to combine like terms. Constants with constants and variables with variables. Since there is only one variable, there is nothing to combine it with so nothing happens to it. The constants, on the other hand, can combine.

2. You have to subtract 28 from 28 and 14 so that +28 can cancel out on the left side and combine on the right.

3. That will leave you with 14x= -14.

4. Now you need to get x on its own so you need to divide 14 (opposite of multiplication to cancel out) on both sides.

5. That will leave you with x= -1. That is your final answer.

A rectangle is 30 inches long. The diagonal is 50 inches how wide is the rectangle?

The answer is 1,500. You have to multiply 30 and 50.

Answer:

40

Step-by-step explanation: A rectangle is  a quadralaterial with 4 90 degree angles made up of two diagonals. If we draw one diagonal, it would split the rectangles into two right triangles. Since a rectangle has a right angle, we can use pythagorean theorem to solve the missing side.              

[tex]a^{2} +b^{2} =c^{2}[/tex]   where a and b are the length and widith  and c is the diagonal length. Let plug it in

Please helppp, I'm using all my points!! Line A passes through the points (-3,-4) and (-6,-5). Write the equation of the image of A after a dilation with a scale factor of 2. Write your in answer in slope-intercept form.

y=

Answers

Answer:

The equation of the image of A after a dilation with a scale factor of 2 will be:

[tex]y\:=\:\frac{1}{3}x\:-6[/tex]

Step-by-step explanation:

Some background Knowledge about dilation.

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

If the scale factor > 1, the image is enlargedIf the scale factor is between 0 and 1, it gets shrunkIf the scale factor = 1, the object and the image are congruent

Rule to calculate the dilation by a scale factor 2 centered at the origin

P(x, y) → P'(2x, 2y)

Here, P'(2x, 2y) is the image of P(x, y).

It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 2.

Now, let us solve our case:

Given the points

(-3, -4)(-6, -5)

Let say the points are X(-3, -4) and Y(-6, -5)

Rule to calculate the dilation by a scale factor 2 centered at the origin

P(x, y) → P'(2x, 2y)

so

X(-3, -4)    →   X' (2(-3), 2(-4))    →    X'(-6, -8)

Y(-6, -5)    →   Y' (2(-6), 2(-5))    →    Y'(-12, -10)

Thus, after the dilation scale of factor 2, now the image line will through the points X'(-6, -8) and Y'(-12, -10)

so we have the points of the image line

X'(-6, -8)Y'(-12, -10)

Determining the slope between X'(-6, -8) and Y'(-12, -10)

[tex]\left(x_1,\:y_1\right)=\left(-6,\:-8\right),\:\left(x_2,\:y_2\right)=\left(-12,\:-10\right)[/tex]

[tex]m=\frac{-10-\left(-8\right)}{-12-\left(-6\right)}[/tex]

[tex]m=\frac{1}{3}[/tex]

The slope-intercept form of the line equation

y = mx+b

where

m is the slopeb is the y-intercept

now substituting m = 1/3 and (-6, -8) in the slope-intercept form of the line equation

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

[tex]-8\:=\:\frac{1}{3}\left(-6\right)\:+\:b[/tex]

[tex]-2+b=-8[/tex]

Add 3 to both sides

[tex]-2+b+2=-8+2[/tex]

Simplify

[tex]b=-6[/tex]

now substituting b = -6 and m = 1/3 in the slope-intercept form of line equation

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

[tex]y\:=\:\frac{1}{3}x\:+\:\left(-6\right)[/tex]

[tex]y\:=\:\frac{1}{3}x\:-6[/tex]

Therefore, the equation of the image of A after a dilation with a scale factor of 2 will be:

[tex]y\:=\:\frac{1}{3}x\:-6[/tex]

The answer to this question is true.

It is worthy to note that in any two points, we have exactly one line segment that connects them together. Now the The distance that lies between both of these points is the length of this line segment which connects them. Also this distance is never negative. It is always positive.

A)0 real solutions
B) 1 real solution
C) 2 real solutions
D) infinitely many real solutions

A) 0 real solutions

Step-by-step explanation:

-2x +12 = x² +16

change side ;

x²+2x+16-12 = 0

x²+2x+4 = 0

(x+2)(x+2) = 0

x = -2
