Answer:
30
Step-by-step explanation:
Original Equation: 2(7 + 8)
So you have to multiply 2 by 7 which equals 14
Then you multiply 2 by 8 which equals 16
Your equation should now look like this: 14 + 16
Add 14 and 16 together.
Your answer is 30

write y=x²+6x-1 in terms of r, given x/r=-3
Given:
[tex]y=x^2+6x-1[/tex]
[tex]\dfrac{x}{r}=-3[/tex]
To find:
The given equation in terms of r if [tex]\dfrac{x}{r}=-3[/tex].
Solution:
Given that,
[tex]\dfrac{x}{r}=-3[/tex]
[tex]x=-3r[/tex]
We have,
[tex]y=x^2+6x-1[/tex]
Substitute x=-3r in the above equation.
[tex]y=(-3r)^2+6(-3r)-1[/tex]
[tex]y=9r^2-18r-1[/tex]
Therefore, the required equation in terms of r is [tex]y=9r^2-18r-1[/tex].
Write an equation of the line passing through point$P(4,-6) that is perpendicular to the line y=-3 . x=
Answer:
x = 4
Step-by-step explanation:
y = - 3 is the equation of a horizontal line parallel to the x- axis.
A line perpendicular to it will therefore be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (4, - 6) with x- coordinate 4, thus
x = 4 ← equation of perpendicular line
write the standard form of the equation that is perpendicular to y = 5x + 4 and goes through point (3, -2).
Answer:
y=-1/5x-7/5
Step-by-step explanation:
y=5x+4
(y+2)=-1/5(x-3)
y+2=-1/5x+3/5
y+10/5=-1/5x+3/5
y=-1/5x-7/5
Answer: x+5y= -7

An entertainment reporter examines the average ticket prices of Broadway shows, comparing them to the number of total performances the shows have had. A resulting scatterplot shows a strong, positive relationship. The value of r for the scatterplot is 0.763. Which statement best explains the relationship between the variables?
Lower ticket prices cause fewer performances to be offered.
Higher ticket prices cause more performances to be offered.
Less popular shows have higher ticket prices and offer fewer performances.
More popular shows have higher ticket prices and offer more performances.
It can be inferred that Broadway shows with higher ticket prices tend to be more popular and offer more performances.
Now,
Since, More popular shows have higher ticket prices and offer more performances.
Hence, Based on the information given, the best explanation for the relationship between ticket prices and the number of performances is that more popular shows tend to have higher ticket prices and offer more performances.
This is supported by the strong, positive relationship indicated by the value of r being 0.763, which suggests that as ticket prices increase, the number of performances tends to increase as well.
Therefore, it can be inferred that Broadway shows with higher ticket prices tend to be more popular and offer more performances.

THINK SMARTER Margot wants to use partial products to find 22 X 17.
Write the numbers in the boxes to show 22 X 17-
Answer:
( 20 × 10 ) + ( 20 × 7 ) + ( 2 × 10 ) + ( 2 × 7 )
Step-by-step explanation:
To create partial products when multiplying two numbers, first break the numbers up into a sum of two numbers. The order that these numbers are multiplied does not necessarily matter as long as they are multiplied with the correct numbers.
22 × 17 = (20 + 2)(10 + 7) = 20 (10 + 7) + 2 (10 + 7) =
( 20 × 10 ) + ( 20 × 7 ) + ( 2 × 10 ) + ( 2 × 7 )
= 374
You can check this method works by using your calculator, and multiplying 22 by 17 to get 374 again!
Then just add like you would if when you distribute.
Remember FOIL (First, Outer, Inner, Last)
when multiplying two binomials(2 terms) or distributing factors with two terms.
For example:
(a + b)(c + d) =
F F
O O
I I
L L
(a × c) + (a × d) + (b × c) + (b × d)

Answer:
C
Step-by-step explanation:
21 - (-5) A negative minus a negitive turns into a +
21 + 5 = 26
A. -21 + 5 = -16 NO
B. 21 - 5 = 16 NO
C. 21 + 5 = 26 YES
D. -21 - 5 = -26 NO
Answer:
C
Step-by-step explanation:
When subtracting a negative, the two negatives cancel out. The rule is that two like signs become positive.
Therefore, +(+) =+ and -(-) = +
So, the equation would be 21 + 5.

is 8/4 equivalent to 10/5?
These are just some equivalent fractions of 8/4:
2/1 = 4/2 = 6/3 = 8/4
= 10/5 = 12/6 = 14/7 = 16/8
= 18/9 = 20/10 = 22/11 = 24/12
= 26/13 = 28/14 = 30/15 = 32/16
= 34/17 = 36/18 = 38/19 = 40/20
= 42/21 = 44/22 = 46/23 = 48/24
= 50/25 = 52/26 = 54/27 = 56/28
= 58/29 = 60/30 = 62/31 = 64/32
= 66/33 = 68/34 = 70/35 = 72/36
= 74/37 = 76/38 = 78/39 = 80/40
= 82/41 = 84/42 = 86/43 = 88/44
= 90/45 = 92/46 = 94/47 = 96/48
= 98/49 = 100/50 = 102/51 = 104/52
= 106/53 = 108/54 = 110/55 = 112/56
= 114/57 = 116/58 = 118/59 = 120/60
= 122/61 = 124/62 = 126/63 = 128/64
= 130/65 = 132/66 = 134/67 = 136/68
= 138/69 = 140/70 = 142/71 = 144/72
= 146/73 = 148/74 = 150/75 = 152/76
= 154/77 = 156/78 = 158/79 = 160/80
= 162/81 = 164/82 = 166/83 = 168/84
= 170/85 = 172/86 = 174/87 = 176/88
= 178/89 = 180/90 = 182/91 = 184/92
= 186/93 = 188/94 = 190/95 = 192/96
= 194/97 = 196/98 = 198/99 = 200/100
So, yes.

What is 6.92 x 10-3 written in standard form?
There are two approaches to solving the equation -3x + 10 = 4x - 20
Subtract 4x from both sides. OR Add 3x to both sides.
–7x + 10 = –20 OR 10 = 7x – 20
Solve the equation using both approaches.

I really don't understand how to do this because I have never been taught this before. Could someone help me out?
Answer: (-6,0) and (-8,0)
!!!!!!Also it's fixed now so ignore my comment about this being wrong!!!!!!
Step-by-step explanation:
To find roots you're basically looking for the points on the graph where they touch the x axis. Those are your roots. You can also plug 0 and -0 in for x and find the coordinates that way with the equation.
Answer:
Two points.
(-8, 0) and (-6, 0)
Step-by-step explanation:
The roots of a graph are another word for the zeros of a graph. In other words, the roots or zeros of a graph are whenever the graph touches or crosses the x-axis. Another way to think about roots are that the roots of a graph are simply its x-intercepts.
From the graph, we can see that it does this twice: once at [tex]x=-8[/tex] and again at [tex]x=-6[/tex]. At both of these points, the graph crosses the x-axis.
Therefore, we will have two roots in this case: one at (-8, 0) and another one at (-6, 0).
So, our answer is two points, being: (-8, 0) and (-6, 0).
And we're done!

What are the steps for using a compass and straightedge to construct a line through point X that is parallel to line r?
Answer:
What are the steps for using a compass and straightedge to construct a line through point X that is parallel to line r? Drag the steps and drop them in order from start to finish. Use the straightedge to draw a line s that passes through X and intersects line r. Label the point of intersection as point Y.
Step-by-step explanation:
Answer:
1. Use the straightedge to draw a line s that passes through X and intersects line r. Label the point of intersection as point Y.
2. Place the point of the compass on point Y and draw an arc that intersects lines r and s. Label the intersections as points M and N.
3. Without changing the width of the compass opening, place the point of the compass on point X and draw an arc that intersects line s. Label the intersection as point P.
4. Place the point of the compass on point M and open it to width MN.
5. With the compass opening set to width MN, place the point of the compass on point P and draw an arc that intersects the arc that was drawn from point X. Label the intersection of the arcs as point Z.
6. Use the straightedge to draw XZ.
