Answer:
23, 5, 3
Step-by-step explanation:
Following the order of operations as stated in PEMDAS , then
(a)
5 + 2 × 3² ← evaluate exponent
= 5 + 2 × 9 ← perform multiplication
= 5 + 18 ← perform addition
= 23
---------------------------------------
(b)
[tex]\frac{7+8}{5-2}[/tex] ← perform calculations on numerator/denominator
= [tex]\frac{15}{3}[/tex] ← perform division
= 5
-------------------------------------------
(c)
[tex]\frac{18-3(2)}{5-1^2}[/tex] ← evaluate numerator/denominator using PEMDAS
= [tex]\frac{18-6}{5-1}[/tex]
= [tex]\frac{12}{4}[/tex]
= 3

Y=
Answers
Answer:
y=55x+160
Step-by-step explanation:
i might be wrong, but i think it would be y=55x+160
Answer:
y=55x+160
Step-by-step explanation:
she starts at 160 mi which is like your y-intercept so the "b" in y=mx+b. the slope or "m" would be 55 because thats how much she's travelling per 1 x or 1 hour
For football tryouts at a local school, 16 coaches and 44 players split into groups. Each group will have the same numbers of coaches and players. How many players will be in each group?
Answers
Answer:
11 players
Step-by-step explanation:
In a football tryouts at a local school there are 16 coaches and 44 players
Therefore spilliting then into group with similar numbers can be illustrated as follows
= 16/4
= 4 coaches each
= 44/4
= 11 players each
Hence sharing them into groups will result in 4 coaches and 11 players for each group

m is the slope
b is the y-intercept
Now, what is the slope?
Hint:- The slope is the coefficient of x, and the y-intercept is the constant.

7/2x + 1/2x = 2 1/2 + 9/2x
solve.
Answers
Answer:
x = -121
Step-by-step explanation:
(7/2)*x+(1/2)*x = (9/2)*x+121/2 // - (9/2)*x+121/2
(7/2)*x+(1/2)*x-((9/2)*x)-(121/2) = 0
(7/2)*x+(1/2)*x+(-9/2)*x-121/2 = 0
-1/2*x-121/2 = 0 // + 121/2
-1/2*x = 121/2 // : -1/2
x = 121/2/(-1/2)
x = -121
How many solutions does the equation 5x + 3x − 4 = 10 have?
a
Zero
b
One
c
Two
d
Infinitely many
Answers
Answer:
1.75
Step-by-step explanation:
5x + 3x - 4 = 10
Add Four To Both Sides To Begin Simplifying.
5x + 3x = 14
Now, Combine Like Terms.
8x = 14
Divide:
8x/8 = 1X = X
14/8
X = 14/8
14/8 = 1.75
X = 1.75
Check:
(5 * 1.75) + (3*1.75) - 4 = 10
8.75 + 5.25 - 4 = 10
14 - 4 = 10
10 = 10. This Is True, So X Does Equal 1.75

What is the answer to (m^2-7m-11)/(m-8)
Answers
Answer:
The final quotient is [tex]\bold{m+1-\frac{3}{m-8}}[/tex].
Step-by-step explanation:
This problem can be solved using two methods: long polynomial division and synthetic division.
Method 1: Long Polynomial Division
We can use long polynomial division to solve the equation. The steps are detailed below the work.
[tex]\displaystyle{\begin{array}{r}\bold{m+1-\frac{3}{m-8}\phantom{)}\\m-8{\overline{\smash{\big)}\,m^2-7m-11\phantom{)}}}\\\underline{-~\phantom{(}m^2-8m\phantom{-b)}}\\m-11\phantom{)}\\\underline{-~\phantom{()}m-8}\\-3\phantom{)}\end{array}}[/tex]
Steps
Set up your division. Place the divisor (the binomial) on the left hand side of the division symbol and the trinomial (or polynomial depending on the amount of terms) on the right hand side of the equation.Divide the divisor by the first term of the trinomial: [tex]\frac{m^2}{m}=m[/tex]Place the result above the first term of the trinomial (above the bar and directly above the first term of the polynomial.Multiply the m by the divisor: [tex]m(m-8) = m^2-8m[/tex]. Subtract this from the original trinomial: [tex](m^2-7m-11)-(m^2-8m)=m - 11[/tex]. Set this below the equation and then divide the leading term of the divisor by the leading term of the remainder: [tex]\frac{m}{m}=1[/tex].Place this to the right of the m located above - in this case, we add because our result is positive.Multiply that by the divisor: [tex]1(m-8)=m-8[/tex].Set this below the remainder from the previous division and subtract: [tex](m-11)-(m-8)=-3[/tex].Finally, divide the original divisor by the remainder: [tex]\frac{-3}{m-8}[/tex]. This divisor needs simplified: [tex]-\frac{3}{m-8}[/tex].Our final new polynomial (once evaluated), is [tex]\bold{m+1-\frac{3}{m-8}}[/tex].Method 2: Synthetic Division
We can also use synthetic division to solve the polynomial.
Table 1 (actual) Table 2 (model)
[tex]\begin{array}{c|ccc}8 & 1 & -7 & -11 \\ & \downarrow & 8 & 8 \\ \cline{2-4} \multicolumn{1}{c}{} & 1 & 1 & -3\end{array}[/tex] [tex]\begin{array}{c|ccc}a & b & c & d \\ & \downarrow & e & f \\ \cline{2-4} \multicolumn{1}{c}{} & g & h & i\end{array}[/tex]
Steps
Determine the coefficients of the polynomial: [tex]m^2-7m-11[/tex]. These are 1, -7, and -11. We need to determine the zero. We do this by setting the divisor equal to zero: [tex]m-8=0\rightarrow m=8[/tex]. Place this value in the upper left hand corner (in place of a).For the first term, we just drop the coefficient below the bar. Therefore, g becomes 1.Multiply a by g to get e : [tex]8 \times 1 = 8[/tex]. Therefore, e becomes 8.Add c to e : [tex]-7 + 8 = 1[/tex]. Therefore, h becomes 1. Multiply a by h to get f : [tex]8 \times 1 = 8[/tex]. Therefore, f becomes 8.Add d to f to get i : [tex]-11 + 8 = -3[/tex]. Therefore, i becomes -3.Our new coefficients are 1, 1, and -3. We lose one power (if the first term is squared, it now does not have an exponent).Use the new coefficients to get our new equation: [tex]m+1-3[/tex].Finally, the last term is the remainder. So, we divide this by the divisor: [tex]m+1-\frac{3}{m-8}[/tex].Our final expression is [tex]\bold{m+1-\frac{3}{m-8}}[/tex].Which one is bigger -4 or -3
Answers
Answer:
the answer is -3 because -3 is closer to 0 than -4
1,900 + 76x. Use the Distributive Property to factor the expression.
Answers
The length of the rectangle is 76 feet and the width of the rectangle was 25 feet that is extended by x feet.
Step-by-step explanation:
The total area, in square feet, of a rectangular stage that has been widened by x feet, is represented by 1,900 + 76x.
Now, factorizing the expression for the area we get,
A = 1900 + 76x
⇒ A = 76(25 + x)
Therefore, from the above expression, we can assume that the length of the rectangle is 76 feet and the width of the rectangle was 25 feet that is extended by x feet. (Answer)
identify the equation in the point-slope form the line parallel to y=3/4x-4 that passes through (-1,7)
Answers
The slope is 3/4 since it is written in the form y =mx+b where m is the slope
We want a line that is parallel so it will have the same slope
We know the slope of the new line (3/4) and a point (-1,7)
So we can use the point slope form of the equation
y-y1 = m(x-x1)
y-7 = 3/4(x--1)
y-7=3/4(x+1)
Which ratio is proportional to 18/28 ?
Help me plzzzz i will give brainliest
Answers
Answer:
18/21 = 30/35
Step-by-step explanation:
so the problem says 18/21 so if that's the correct ratio to proportion to the answer would be. 30/35. the reason is that you can divide 18 and 21 by 3 to get 6/7 then if you multiply by 5 you get 30/35. Dividing and multiplying both the denominator and numerator keeps the ratio proportional.
