Answer:
100
Step-by-step explanation:
We have the number 91 and are asked to round to the nearest 100.
When we round to a certain number, we always have to look at the number to the right of the place value being rounded to, if the numbers is 0-4, you will round down, if the number is 5-9, you round up.
Right now we have 094, 0 being the hundreds place, look to the right and see that we have 9. Therefore we round up.

Answer:
㏒(2x²) = ㏒(2) + 2㏒(x)
Step-by-step explanation:
As given, ㏒(2x²)
As we know that ㏒(MN) = ㏒(M) + ㏒(N)
⇒㏒(2x²) = ㏒(2) + ㏒(x²)
As we know that ㏒(xⁿ) = n㏒(x)
⇒㏒(2x²) = ㏒(2) + 2㏒(x)
∴ we get
㏒(2x²) = ㏒(2) + 2㏒(x)

luca sells muffins and juice boxes. muffins are $1.50 each and jucie boxes are $1.25 each. write an algebraic expression for the total income luca received from the sale of muffins and juice boxes
Answer:
1.5m+1.25j
Step-by-step explanation:
m equals the number of muffins sold, and because each muffin sells for $1.50, 1.5m represents the income made from the muffins.
Same thing with the juice boxes, j equals the number of juice boxes sold, and because each juice box sells for $1.25, 1.25j represents the income made from the juice boxes.
Add the income from both of them to get the total income, and you get 1.5m+1.25j.
Find the value of c so that the polynomial p(x) is divisible by (x-3). p(x) =-x^3+cx^2-4x+3. c=?
Answer:
[tex]\boxed{\textsf {The value of c is $\sf \dfrac{-14}{3}$. }}[/tex]
Step-by-step explanation:
A polynomial is given to us . We need to find the value of c so that it is divisible by (x-3 ) .The given polynomial to us is ,
[tex]\sf \implies p(x)=- x^3+cx^2-4x+3 [/tex]
And the factor is ,
[tex]\sf \implies g(x) = x + 3 [/tex]
Now , according to factor theorem , p(x) will be divisible by g(x) if p(-3) = 0
[tex]\sf \implies p(x)= - x^3+cx^2-4x+3 \\\\\implies\sf p(-3) = 0 \\\\\sf\implies -(-3)^3+c(-3)^2-4(-3)+3 = 0 \\\\\sf\implies 27 + 9c +12+3=0 \\\\\sf\implies 9c +42=0 \\\\\sf\implies 9c = (-42) \\\\\sf\implies c = \dfrac{-42}{9}\\\\\sf\implies \boxed{\pink{\sf c = \dfrac{-14}{3}}}[/tex]
Hence the value of c is (-14)/3 .The value of c will be equal to -14/3.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is p(x) =-x³+cx²-4x+3. The value of c will be calculated as,
p(x) =-x³+cx²-4x+3
p(-3) =-(-3)³+c(-3)²-( 4 x -3) +3
p(-3) = 27 + 9c +12 + 3
27 + 9c +12 + 3 = 0
9c = -42
c = -42/9
c = -14/3
Therefore, the value of c will be equal to -14/3.

What is the solution set of 4x = y and [tex]2x^{2} -y=0[/tex]
A.
{(0.5, -0.5), (2, -8)}
B.
{(0, 0), (2, 8)}
C.
{(1.5, 2), (8, 2)}
D.
{(-1.5, -2), (2, 8)}
Answer:
B.
{(0, 0), (2, 8)}
Step-by-step explanation:
Substitute 4x in for y in the second equation.
[tex]2x^{2} - 4x = 0\\[/tex]
2x(x - 2) = 0
x = 0 or x - 2 = 0
x = 2
Substitute x = 0 and x = 2 in the first equation to get the corresponding values for y
4(0) = y and 4(2) = y
y = 0 or y = 8
So, B is the correct answer
2. A bag of dog food weighs 40 lb. By weight, 16% of the ingredients is turkey. Find the weight of turkey in the

Answer:
Pretty sure it's 6.4 lbs
Step-by-step explanation:
We have to set up a proporion. So ?/40 and 16/100 because 16% of 100. Since we can't cross multiply 100 and ?, we have to cross multiply 16 × 40 = 640. We have 100 leftover, so 640÷100=6.4

Identify a set of parallel lines and a set of perpendicular lines in this image
Answer
It is the first answer.
Step-by-step explanation:
Parallel lines are lines that will never cross each other.
Perpendicular lines are lines that cross each other at 90 degree angles (represented by the box in the corner).
A set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since Parallel lines are lines that will never cross each other.
We know that Perpendicular lines are lines that cross each other at 90 degree angles.
The parallel lines are AB and CD, the perpendicular are AB and EF because the first sets are side by side and the second sets cross each other at a certain point.
Therefore the set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF

Solve the system by substitution.
x= -5y - 6
5x – 3y = -2
What’s is the solution?
The value of x is -1 and value of y is -1.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are
x+5y=-6...(1)
5x – 3y = -2...(2)
Multiply equation 1 with 5
5x+25y=-30..(3)
Subtract equation 2 and equation 3
5x-3y-5x-25y=-2+30
-28y=28
Divide both sides by 28
y=-1
Now plug in y value in equation 1
x=5-6
x=-1
Hence, the value of x is -1 and value of y is -1.
