Mathematics
1 answer:
Korvikt [17]3 years ago

Answer:

g=79

h=55

j=75

Step-by-step explanation:

1. When a transversal intersects two parallel lines corresponding angles, angles that are located in the same relative position an intersection of transversal and two or more straight lines, are congruent. Therefore g=79.

2. Since the two lines are parallel same side interior angles are supplementary. This means they add up to 180. So to find h solve the equation h+125=180. Once solved you get 55.

3. Like question 2, these angles are same side interior and therefore supplementary. To find j solve the equation j+105=180, which gets j=75.

Y varies directly as the cube of x. When x = 3, then y = 7. Find y when x = 4.
LUCKY_DIMON [66]

Answer:

y \:  \alpha   \: {x}^{3} \ \\ y \:  = k {x}^{3}   \\ where \: y = 7 \: and \:x = 3 \\ y = k {x}^{3} \\ 7 = k ( {3)}^{3} \\ 7 = 27k \\ k =  \frac{7}{27}  \\  \\ so \:  \: y =  \frac{7}{27}  {x}^{3}  \\  \\ y =  \frac{7}{27}  {4}^{3}  \\ y =  \frac{448}{27}

Analyze the pre-image ABCD. What are the vertices of the final image if T-1, -2 •Ty=x is applied to figure ABCD? B"(3, 2) D - 2
schepotkina [342]

In Mathematics, it is possible to describe a graph as a pictographic depiction of a chart that helps to shape represents data or values, and in this question, the missing graph is defined in the attachment, and the solution can be defined as follows:

  • In the first place, we reflect on y=x.
  • The X and Y coordinates are changed in this reflection, which is given in the map:

                         A(2, 4)\to A'(4, 2)\\\\B(4, 4)\to B'(4, 4)\\\\C(3, 2) \to  C'(2, 3) \\\\D(1, 2)\to D'(2, 1)

  • We're doing the translation next.
  • The translation shifts figure 1 from the left and 2 from the y-coordinate by removing one at the x-coordinate and two that are:

                 A'(4, 2)\to A''(3, 0) \\\\B'(4, 4)\to B''(3, 2) \\\\C'(2, 3)\to C''(1, 1)\\\\D'(2, 1)\to D''(1, -1) \\\\

Therefore the final answer is "A''(3, 0); B''(3, 2); C''(1, 1); D''(1, -1)"

  • please find the image file into the attachment.

An electrician charges a set fee of $100 for every house call and then charges an additional hourly rate. One day, the electrici
DIA [1.3K]

Answer:

C=75t+100

Step-by-step explanation:

Let

C(t) ---->the total cost of the electrician's services in dollars

t ---> the number of hours

we know that

The linear function in slope intercept form is equal to

C=mt+b

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

the y-intercept is equal to

b=\$100 ----> set fee

we have the ordered pair (2,250)

substitute the given values

250=m(2)+100

Solve for m

2m=250-100

2m=150

m=\$75\ per\ hour

The linear function is equal to

C=75t+100
