Answer:
y = 10
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 20 when x = 4 and z = 3 , then
20 = k × 4 × 3 = 12k ( divide both sides by 12 )
[tex]\frac{20}{12}[/tex] = k , that is
k = [tex]\frac{5}{3}[/tex]
y = [tex]\frac{5}{3}[/tex] xz ← equation of variation
When x = 2 and z = 3 , then
y = [tex]\frac{5}{3}[/tex] × 2 × 3 = 5 × 2 = 10

Answer:
2 <= x < 8
Step-by-step explanation:
2 is less than or equal to x and the symbol for that is <=
the least number should also be on the left side
8 is greater than x so the symbol is <
8 is the biggest number and goes on the right
COS Find the quotient when the polynomial expression is divided by a binomial Find the quotient ANSWER SOLUTION CHOICES X2+11x+ 10) = (x+1) = Long Division Synthetic Division Answer: X2 + 5x + 1
Answer:
x=−1 or x=−9
Step-by-step explanation:
x2+11x+10=x+1
Step 1: Subtract x+1 from both sides.
x2+11x+10−(x+1)=x+1−(x+1)
x2+10x+9=0
Step 2: Factor left side of equation.
(x+1)(x+9)=0
Step 3: Set factors equal to 0.
x+1=0 or x+9=0
x=−1 or x=−9
what is the difrence between domain and range
Answer:
Domain is the set of all possible input values is any relation. It means the output value in a function depends upon each member of domain. Domain value vary in different mathematical problems and depends upon the function for which is it solved. If we talk about cosine, then domain is the set of all possible real numbers either above the 0 value or below the 0 value, it could also be 0. While for square root, the domain value could not be less than 0, it should be minimum 0 or above 0. In other words, you can say that domain of square root is always 0 or positive value. For complex and real equations, the domain value is a subset of complex or real vector space. If we want to solve a partially differential equation for finding the value of domain, then your answer should lie within three dimensional space of Euclidean geometry.

six times the difference of a number and three is -42 (write and equation and solve)
Here's ur perfect answer
Hello!
6(3-x)=-42
Use the Distributive Property:
18-6x=-42
-6x=-42-18 (move all the constants (numbers) to the right side, using the opposite operation)
-6x=-60
6x=60
Divide both sides by 6:
x=10

1/4(2x + 1.2) = 3(0.7x + 3) - 5 1/2
Answer:
x=-2
Step-by-step explanation:
Simplify parentheses : 0.5x+0.3=2.1x+9-5.5
Combine like terms : 0.5x+0.3=2.1x+3.5
Isolate the variable : -1.6x=3.2
Divide by -1.6 on both sides : x=-2
Answer:
x=-2
Step-by-step explanation:
1/4(2x + 1.2) = 3(0.7x + 3) - 5 1/2
multiply both sides of the equation by 4 to get rid of the fraction 1/4
2x+1.2=12(0.7x+3)-4*5 1/2
distribute 12 into parenthesis
2x+1.2= 8.4x+36-4*5 1/2
multiply -4 with 5 1/2
2x+1.2=8.4x+36-22
subtract numbers
2x+1.2= 8.4x+14
move X's to one side and numbers to another
2x-8.4x=14-1.2
collect like terms
-6.4x=12.8
divide by -6.4 to get x
x= -2

Cherries cost $4.35 per pound and onions cost $0.98 per pound. Lacey has $21.45 to spend. How many pounds of cherries can Lacey afford if she
has to buy 3 pounds of onions?
Answer:
Lacey could afford 4.25lb of cherries
Step-by-step explanation:
Cost of onions= 3 lb x 0.98/1=2.94
21.45-2.94=18.48$
1 lb=4.35
18.48 x 1lb of cherries/4.35=4.25lb of cherries.

Which quadratic function shows a y-intercept of 4 and a maximum value of 5
Answer:
The 4th graph
Step-by-step explanation:
To have a maximum value, your parabola would have to open downwards. So the first 2 are wrong. Since your y-intercept is positive 4, your graph would have to touch the y axis at 4. The 3rd graph is wrong since it touches the y-axis at a negative point. The correct answer would be the 4th answer choice.
There is a line that includes the point (-20, -7) and has a slope of 1. What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y=1x+13
Step-by-step explanation:
we can plug in the two points into the slope-intercept formula
-7=-20(1)+b
solve for the right side
-7=-20+b
add 20 to both sides
13=b
plug the y intercept into the equation
y=1x+13

To find this we can look for the [tex]LCD[/tex] between all the numbers
Here are our [tex]LCD's[/tex] (Least Common Denominator)

It wouldn't be -1 because it isn't in between those numbers
It isn't -7/10 because if we turn it into our [tex]LCD[/tex] it would be -21/30 which isn't in between those numbers
It is -4/5 because if we turn in into our [tex]LCD[/tex] it would be -24/30 which is between those numbers
