Y -7=2
6. Help me please ayuda
Answer:
54
Step-by-step explanation:
First add 7 to both sides to cancel out the -7
y/6-7(+7)=2(+7)
Then, multiply 6 to both sides to cancel the 6
y/6(6)=9(6)
y=54

3.4 code practice: Question 1
Answer:
color = input("What color? ")
if (color == "yellow"):
print("Correct!")
else:
print("Nope")
Can you solve this by explaining.
Answer:
The answer is 1
Step-by-step explanation:
Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.
f the line with equation y=−2x+7 is rotated 90° clockwise about the origin, what are the coordinates of the image of its y-intercept?
A. (2,0)
B. (7,0)
C. (0,−7)
D. (−7,0)
Answer:
B
Step-by-step explanation:
I looked it up
The line with equation y=−2x+7 is rotated 90° clockwise about the origin, the coordinates of the image of its y-intercept is D (−7,0).
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
To find the y-intercept of the line y=-2x+7. When x=0 we have that y=-2·0+7, y=7,
then point (0,7) is the y-intercept.
When we rotate this line 90° clockwise about the origin, then point (0,7) will be placed on the x-axis in positive x-direction.
Rotation preserves the distances, then the coordinates of the image are (7,0).
The correct choice is D (−7,0).

18 students took the bus to school.
Step-by-step explanation:
If 1/4 of the students walked, that leaves 3/4 of the students who did not walk. That leaves 22.5 students. Out of these students 22.5, 4/5 of them take the bus, and 4/5 of 22.5 is 18.

[tex]\overline W\overline X = \overline Y\overline Z[/tex] (given)
[tex]\angle WXZ = \angle YZX[/tex] (alternate angles are equal, [tex]\overline W\overline X\parallel \overline Y\overline Z[/tex])

Please help me circles.....
Answer:
95
Step-by-step explanation:
The equation is
x×2=285-x
3x=285
x=95
Answer:
x = 75°
Step-by-step explanation:
There are many Circle Geometry Rules. We will be using the following:
The angle at the centre of the circle is twice the angle at the circumference.
x = the angle opposite 285 - x.
This means that 360 - (285 - x) = 2x
360 - 285 + x = 2x
75 + x = 2x
We can simplify this by taking away x from both sides.
75 = x
We can check this by substituting x into the orginal equation.
360 - (285 - x) = 2x
360 - (285 - 75) = 2 * 75
360 - 210 = 2 * 75
150 = 2*75
150 = 150

Emma's grandmother sent her an $80 bookstore gift card for her birthday. Emma wants to make sure that her purchases don't exceed the amount of her gift card. So far, she has selected books that cost $8.95, $11.95, $22.25, and $24.95. She has also found a calendar she likes for $8.25. Round each item up to the next dollar to overestimate the total cost of the items in Emma's shopping basket.
Answer: total cost of the estimated items = $76
Step-by-step explanation:
Step 1
Rounding up each item to the next dollar
Book 1 = $8.95 ≈ $9.00
Book 2 = $11.95≈ $12.00
Book 3 = $22.25≈$22.00
Book 4 = $24.95≈$25.00
Calendar = $8.25 ≈$8.00
Step 2
The total estimated cost of items in Emma's shopping basket =$9.00+$12.00+$22.00+$25.00+$8.00
=$76 which did not exceed the amount of bookstore gift card of $80 sent by her grandmother.
Answer: 78$
Actual Estimate
$8.95 --------------------------$9.00
$11.95--------------------------$12.00
22.25--------------------------$23.00
$24.95------------------------$25.00
$8.25--------------------------$9.00
Then add the estimate numbers to get $78

Evaluate the expression 15g if g = 1/5.
Answer:
3
Step-by-step explanation:
15g
g=1/5
15×1/5
15/1×1/5=3
Answer:
3
Step-by-step explanation:
This is the answer because:
1) We have to substitute the value into the equation:
15(1/5)
2) Next, we have to mutiply 15 and 1/5 together since the g is just a variable that is supposed to be mutiplied with 15:
15(1/5) = 15/5 = 15 ÷ 5 = 3
Therefore, the answer is 3.

Jerry has a part-time job at a supermarket. The ordered pairs show the number of hours he worked for (input values) and the number of dollars (output values) he earned over a five week period. (6,72) (8,96) (5.5, 66) (9,108) (7,84) Are the ordered pairs a relation?
Answer:
Yes
Step-by-step explanation:
The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).
The number of hours worked is [tex]x[/tex] and the money earned is [tex]y[/tex].
Let us divide the values of [tex]y[/tex] by [tex]x[/tex]
[tex]\dfrac{72}{6}=12[/tex]
[tex]\dfrac{96}{8}=12[/tex]
[tex]\dfrac{66}{5.5}=12[/tex]
[tex]\dfrac{108}{9}=12[/tex]
[tex]\dfrac{84}{7}=12[/tex]
The fuction which defines the above ordered pairs is [tex]y=12x[/tex]
It can be seen that the amount of money earned is 12 times the number of hours worked.
So, per hour Jerry earns 12 dollars.
Hence, the ordered pairs are relation.

Step-by-step explanation:
Josie has $30 to spend at a festival .It cost $5 to enter the festival and the game she wants to play cost $1.40 .Write the inequality and use it to determine the number of games that Josie can play
Answer:
At the maximum Josie can be 17 games.
Step-by-step explanation:
Given that:
Total money available with Josie to be spent at a festival = $30
Entry ticket for the festival = $5
Ticket for each game = $1.40
To find:
The inequality to represent the situation and the number of games that Josie can play.
Solution:
Ticket for 1 game = $1.40
Let [tex]n[/tex] number of games can be played.
So, Ticket for [tex]n[/tex] games = $1.40[tex]n[/tex]
Total money spent = $1.40[tex]n[/tex] + $5
It is should be lesser than or equal to $30.
[tex]1.40n + 5 \leq 30\\\Rightarrow 1.40n \leq 25\\\Rightarrow n \leq 17.8[/tex]
Therefore, at the maximum Josie can be 17 games.
