Answer:
C) Addition property of equality and division property of equality
Step-by-step explanation:
To find the answer, let's first solve the equation for x...
3x-6=12
Add 6 to both sides (Addition property of equality)
3x=6
Divide both sides by 3 (Division property of equality)
x=2
We used both the addition property of equality and the division property of equality therefore the answer is C
Find the first four terms of the sequence given by the following.
aₙ=43-3(n-1) n=1,2,3. . .
Given :-
The general term of a sequence is given by aₙ=43-3(n-1) .To Find :-
The first four terms of the sequence.Solution :-
The given expression is [tex] /[/tex]
→ aₙ=43-3(n-1)
where n > 0
Finding the first term :
Substituting n = 1 , we have ,
→ T1 = 43 - 3(1-1)
→ T1 = 43 - 3*0
→ T1 = 43 - 0 = 43
Finding the second term :
Substituting n = 2 , we have,
→ T2 = 43 -3(2-1)
→ T2 = 43 -3*1
→ T2 = 43 -3 = 40
Finding the third term :
Substituting n = 3 , we have,
→ T3 = 43 -3(3-1)
→ T3 = 43 -3*2
→ T3 = 43 -6 = 37
Finding the fourth term :
→ T4 = 43 -3(4-1)
→ T4 = 43 -3*3
→ T4 = 43-9 = 34
Hence the first four terms of the sequence are 43 , 40 , 37 and 34 .

Solve for m
bm + h = 93
Answer:
m = 93 - h / b
Step-by-step explanation:
bm + h = 93
bm = 93 - h
m = 93 - h / b
Hope it helps ⚜
Answer:
[tex]bm + h = 93 \\ add \: h \: to \: both \: sides \\ bm + h + - h = 93 + - h \\ bm = - h + 93 \\step2 \: \: divide \: both \: sides \: by \: b \\ \frac{bm}{b } = \frac{ - h + 93}{b} \\ m = \frac{ - h + 93}{b} [/tex]

Answer:
5. (x,y) = (2.3)

{3 = 1/2 x 2 + 2
{3 = 2 + 1
{3 = 3
{3 = 3
Answer:
3. no solution
5. (x, y) = (2, 3)
Step-by-step explanation:
3.-5x +y = 1
-10x +2y = -2
Multiply the first equation by -2 and add the second equation:
-2(-5x +y) +(-10x +2y) = -2(1) +(-2)
10x -2y -10x +2y = -2 -2 . . . . eliminate parentheses
0 = -4 . . . . . . . . . no variable values will make this true: NO SOLUTION
(The lines graph as parallel lines.)
__
5.y = 1/2x +2
y = x +1
Subtract the first equation from the second:
(y) -(y) = (x +1) -(1/2x +2)
0 = 1/2x -1
0 = x -2
2 = x
y = x +1 = 2 +1 = 3 . . . . use the second equation to find y
The solution is (x, y) = (2, 3).

Step-by-step explanation:
Please Factor -5x²+13x+6
Answer:
[tex](x-3)(-5x-2)[/tex]
or [tex]-(x-3)(5x+2)[/tex]
Step-by-step explanation:
quadratic equation format: [tex]a^2+b^2+c[/tex]
Therefore, for [tex]-5x^2+13x+6[/tex], a = -5, b = 13 and c = 6
Multiply the coefficient of [tex]x^2[/tex] ([tex]a[/tex]) by the constant term ([tex]c[/tex])
[tex]\implies -5 \times 6 = -30[/tex]
Find two numbers which have a product of -30 and a sum of [tex]b[/tex] (13)
Factors of 30: 1 and 30, 2 and 15, 3 and 10, 5 and 6
So -2 and 15 have a product of -30 and sum of 13.
Rewrite [tex]13x[/tex] as [tex]15x-2x[/tex] and substitute into the equation:
[tex]\implies -5x^2+15x-2x+6[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies-5x(x-3)-2(x-3)[/tex]
The bracket created should always be the same.
The two brackets have now been found. The first bracket is the common factor of (x - 3). The second bracket is the factorized terms outside of each bracket (-5x - 2).
[tex]\implies (x-3)(-5x-2)[/tex]
Additionally, we can write (-5x - 2) as -(5x + 2)
[tex]\implies -(x-3)(5x+2)[/tex]

what is the area of the shaded triangle?
steps please
Answer:
area of shaded: 30 m²
Explanation:
Here triangle is inscribed in a rectangle.Rectangle area: Length * WidthTriangle area: (1/2) * base * heightThe triangle here is shaded.Steps:
Rectangle area: 6 * 10 = 60 m²
Triangle area: (1/2) * 6 * 10 = 30 m² .......this is the area of shaded.
Answer:
30m²
Step-by-step explanation:
Let's derive the area of a triangle
We know the formula for the area of a rectangle:
[tex]\text{A = l * w}[/tex]Here, we can see that the area of the triangle is the rectangle's are divided by 2, or half of the rectangle's area.
Here's the formula for the area of a triangle:
[tex]\text{A} = \frac{1}{2}\text{b * h}[/tex]B is the base, the same as the length
H is the height, the same as the width
Solve:
[tex]\text{A} = \frac{1}{2}\text{b * h}[/tex][tex]\text{A} = \frac{1}{2}(10 * 6)[/tex][tex]\text{A} = \frac12(60)[/tex][tex]\text{A} = 30\\[/tex]The units is m * m, or m²

A rectangle with a length of 3 and a height of 8 has two right triangles on each side of it with short leg lengths of 7.
Answer:
80 squared units.
Step-by-step explanation:
7 × 8 = 56 u squared for the triangles
you don't need to divide by two because there are two triangles.
3 × 8 = 24 u squared for the rectangle
56 + 24 = 80 squared u

Joy and Willa left $3 each for a tip on a $44 restaurant bill. They are sharing the bill. How much does each person owe??
Over the last three evenings, Ann received a total of 70 phone calls at the call center. The first evening, she received 6 more calls than the third evening. The second evening, she received 2 times as many calls as the third evening. How many phone calls did she receive each evening? Number of phone calls the first evening: Number of phone calls the second evening: Number of phone calls the third evening:
Let x represent the number of calls received on the second evening.
The number of calls received on the first evening is x - 10.
The number of calls received on the third evening is 2x.
The sum of calls received on the three evenings is (x - 10) + x + 2x, and this is equal to 50:
(x - 10) + x + 2x = 50
4x - 10 = 50
4x = 50 + 10
4x = 60
x = 60/4
x = 15
The number of calls received on each evening is then:
First evening: x - 10 = 15 - 10 = 5
Second evening: x = 15
Third evening: 2x = 2(15) = 30
Check: 5 + 15 + 30 = 60

The average value of a function f over the interval [−1,2] is −4, and the average value of f over the interval [2,7] is 8. What is the average value of f over the interval [−1,7] ?
The average value of a continuous function f(x) over an interval [a, b] is
[tex]\displaystyle f_{\mathrm{ave}[a,b]} = \frac1{b-a}\int_a^b f(x)\,dx[/tex]
We're given that
[tex]\displaystyle f_{\rm ave[-1,2]} = \frac13 \int_{-1}^2 f(x) \, dx = -4[/tex]
[tex]\displaystyle f_{\rm ave[2,7]} = \frac15 \int_2^7 f(x) \, dx = 8[/tex]
and we want to determine
[tex]\displaystyle f_{\rm ave[-1,7]} = \frac18 \int_{-1}^7 f(x) \, dx[/tex]
By the additive property of definite integration, we have
[tex]\displaystyle \int_{-1}^7 f(x) \, dx = \int_{-1}^2 f(x)\,dx + \int_2^7 f(x)\,dx[/tex]
so it follows that
[tex]\displaystyle f_{\rm ave[-1,7]} = \frac18 \left(\int_{-1}^2 f(x)\,dx + \int_2^7 f(x)\,dx\right)[/tex]
[tex]\displaystyle f_{\rm ave[-1,7]} = \frac18 \left(3\times(-4) + 5\times8\right)[/tex]
[tex]\displaystyle f_{\rm ave[-1,7]} = \boxed{\frac72}[/tex]
