9) ** The sum of the digits of a certain two-digit number is 7. Reversingits agits decreases the
number by 63. Find the number.
The number is
Answer:
The required number is 70.
Step-by-step explanation:
let the no. be 10y + x where x is unit digit and y is ten's digit.
given , sum of the digit is 7
x + y = 7 ...(1)
also , reversing the no. we get 10x + y ,where x is ten's digit and y is unit digit.
given reversed digit decreases the number by 63 .
so, 10y + x - ( 10x + y ) = 63
9y -9x = 63
( dividing both side by 9 )
y - x = 7 ....(2)
adding 1 and 2 [ refer attachment ]
so the required original number is
10y + x = 10×7+0 = 70

Answer:
Step-by-step explanation:
Use DESMOS to plot both lines (attached).
If you make your own lines on the graph paper, pick two points for each line and connect them with a ruler. Both are straight lines, so we only need two points.
Pick any two values of x and solve each equation for y. I picked x = 1 and 3
EQ1: y=2x-2
EQ2: y=-x+4
Value of y EQ1 EQ2
x =1 0 3
x =3 4 1
Plot the points (1,0) and (3,4) for EQ1.
Do the same for EQ2: (1,3) and (3,1)
The attached graph shows these points. Note that one can draw stright lines for both equations using only these two points.

Which of the following is a solution to the inequality below?19 ≥ 5k + 6
Answer:
k ≥ 13/5 or k ≥ 2.6 ( same thing )
Step-by-step explanation:
symbol stays the same throughout (≥)
subtract 6 from both sides of the symbol ( 13 ≥ 5k)
divide both sides by 5 (13/5 ≥ k )
your answer can be written as k ≥ 13/5 or k ≥ 2.6

Answer:
-47
Step-by-step explanation:
First term in the sequence is given as 30. The common difference (difference between first term and next term) is -7. Since we are looking for the 12th term we can do 30 - (11 * -7) = -47. It's 11 * -7 because we already are given one term in the problem statement.

Step-by-step explanation:
[tex]81x^{3}-36x[/tex]
9(9x³ - 4x)
9x(9x² - 4)
Since both terms are perfect squares factor using the difference of squares formula, a² - b² = (a + b) (a - b)
Therefore, 9x(3x-2) (3x+2)
Answer:
81z^3-36z = 9z(3z-2)(3z+2)
Step-by-step explanation:
(81z^3-36z)=9z(9z^2-4)
9z(9z^2-4)=9z(3z-2)(3z+2)
81z^3-36z=9z(3z-2)(3z+2)

Find the value of y to the nearest tenth.
Step-by-step explanation:
the easiest approach seems to be the law of sines :
a/sin(A) = b/sin(B) = c/sin(C)
where the sides and the angles are always opposite of each other.
we have here a right-angled triangle, so the angle opposite of 10 is 90 degrees.
10/sin(90) = 10/1 = 10 = y/sin(37)
y = 10×sin(37) = 6.018150232 ≈ 6.0

1. Fill in the blanks with <,> or =
(a) 7/-13 □ -8/15
(b) 5/8 □ -9/14
(c) -11/16 □ 13/-16
(d) -9/-13 □ 36/52
Step-by-step explanation:
(a)→ Given numbers are 7/-13 and -8/15
LCM of 13 and 15 = 195
7/-13
= -7/13
= (-7/13)×(15/15)
= (-7×15)/(13×15)
= -105/195
and
-8/15
= (-8/15)×(13/13)
= (-8×13)/(15×13)
⇛ -104/195
So,
-105/195 < -104/195
-7/13 < -8/15
(b)→ Given numbers are 5/8 and -9/14
We know that
Negative numbers are always less than positive numbers
5/8 > -9/14
(c).→Given numbers are -11/16 and 13/-16 = -13/16
-11/16 >-13/16
(d)→Given numbers are -9/-13 = 9/13 and
36/52 = 9/13
Both are same
-9/-13 = 36/52

Answer:
Step-by-step explanation:
Let's start by looking at the graph of the two equations.
Since you are not looking for where the lines cross, I have chosen any 3 points for each equation almost randomly. I have not used either the x or y intercepts except once.
As a sample for the method of calculation
Let x -2y = 4
Let x = -2. Find y and put it in the table
-2 - 2y = 4 Add 2 to both sides
-2+2-2y = 4 + 2 Combine
-2y = 6 Divide by -2
y = 6/-2
y = - 3
Put that in the table under the first equation.
The other 5 points are done the same way.

Solve the equation: [tex]x^{2} +5x+6=0[/tex]
I know [tex]x^{2} +5x+6=(x+3)(x+2)[/tex] (that was part a) but I don't know where to go from here!
Step-by-step explanation:
but then you did already the most work.
because just think : when is the expression
(x+3)(x+2) equal to 0 ?
only, if at least one factor of the multiplication is equal to 0.
you know, for example, 5×0 = 0, or 0×3 = 0.
that means either (x+3) or (x+2) must be 0.
x + 3 = 0
x = -3
and
x + 2 = 0
x = -2
and there you have it.
a quadratic equation (with the highest x exponent is 2) has 2 solutions for being 0.
and this one here has the 2 solutions
x = -3 and
x = -2
again, by finding the factors you did already the biggest and most difficult part yourself. congratulations !
Corrine ran 4 miles in 28 minutes yesterday and
5 1/2 miles in 32 minutes
todoy Did she run
foster today or
yesterday?
Answer:
Step-by-step explanation:
First things first, you need to find out how many minutes it took Corrine to run one mile each day. To do this, you divide 4 by 4 and 28 by 4
4 ÷ 4 = number of miles
4 ÷ 4 = 1 mile
28 ÷ 4 = number of minutes for one mile
28 ÷ 4 = 7 minutes for one mile
Next, you need to divide 5.5 by 5.5 and 32 by 5.5
5.5 ÷ 5.5 = number of miles
5.5 ÷ 5.5 = 1 mile
32 ÷ 5.5 = number of minutes for one mile
32 ÷ 5.5 = 5.81818181818
So, Corrine ran one mile in 7 minutes yesterday and ran one mile in 5.81818181818 today.
All in all, Corrine ran faster today than yesterday.
Hope this helps!
