Answer:
10/18 Hours
Step-by-step explanation:
Clair Mowed 5 lawns last week
Time Taken last week= 5×7/18
=35/18 Hours
Clair Mowed 5 lawns this week
Time taken this week=5×5/18
=25/18 Hours
Clair takes: 35/18 - 25/18 = 10/18 times longer.
∠1 and ∠2 are supplementary angles. If m∠1 = 77°, then m∠2 =
Answer:
m∠2 = 103°
Step-by-step explanation:
Since ∠1 and ∠2 are supplementary angles, together they equal 180. So, you would just subtract 180-77 and get 103. To check if you are correct just add ∠1 and ∠2 ( 77+103) and you'll get 180 :)

the ratio of red marbles to yellow marbles placed in a bag is 2:7. More marbles are added to the bag: 3 red and 3 yellow marbles. Maria states that the ratio is still the same since equal amounts of red and yellow marbles were added to the bag
Answer: False.
Step-by-step explanation:
Initially, the ratio is 2:7
This means that if we have 2 red marbles, we must have 7 yellow ones.
The quotient here is 7/2 = 3.5
Now, if you add 3 marbles of each colour, then we have:
2 + 3 = 5 red marbles
7 + 3 = 10 yellow marbles.
Now the ratio is 5:10
This means that for every 5 red marbles, we have 10 yellow ones.
But now we can divide both numbers by the same positive integer, because they have a common factor equal to 5.
5/5 = 1
10/5 = 2
Then we have:
5:10 = 1:2
So the new ratio is 1:2
Then the ratio changed when we added the new marbles, which means that Maria was wrong.

Given points A(0, 0), B(3, 2), and C(−2, 3), which statement is true?
BC is perpendicular to CA.
AB is perpendicular to AC.
AB is parallel to AC.
AB is longer than BC.
Answer:
AB is parallel to AC
Step-by-step explanation:
the product of the gradients of perpendicular line should be -1
AB=2/3
AC=-3/2
2/3*-3/2=-1
=-1
The correct statement is,
⇒ AB is perpendicular to AC.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
We have to given that;
Points are,
A(0, 0), B(3, 2), and C(−2, 3),
Now, We can find slopes as;
AB = (2 - 0) / (3 - 0)
AB = 2/3
AC = (3 - 0)) / (- 2 - 0)
AC = - 3/2
Hence, AB is perpendicular to AC.
Thus, The correct statement is,
⇒ AB is perpendicular to AC.

what is the constant of the function f(x)=8x(squared 2) - 7x+6
Answer:
6
Step-by-step explanation:
A constant has no variables multiplied to it.
f(x) = 8x² - 7x + 6
8x² and -7x would have variables and would be terms.
6 would just be a constant cause it doesn't change.

A family has two cars. During one particular week, the first car consumed 30 gallons of gas and the second consumed 20 gallons of gas. The two cars drove a
combined total of 1050 miles, and the sum of their fuel efficiencies was 45 miles per gallon. What were the fuel efficiencies of each of the cars that week?
Answer:
30 mpg15 mpgStep-by-step explanation:
Let x represent the fuel efficiency of one of the cars. Then 45-x is the fuel efficiency of the other. The total miles driven is then ...
miles = (gallons)×(miles/gallon)
20x +30(45-x) = 1050
-10x +1350 = 1050 . . . simplify
300 = 10x . . . . . . . . . . add 10x-1050
x = 30 . . . . . . . . . . . . . divide by 10
45-x = 45-30 = 15
The car using 20 gallons got 30 miles per gallon; the car using 30 gallons got 15 miles per gallon.

Evaluate f(x) = -4x + x2 + 16 for f(-4).
Answer:
[tex]f(-4)=48[/tex]
Step-by-step explanation:
Value of functions
To evaluate a function for a given value of x, we replace the x for the value and perform the resulting operations.
The given function is (corrected):
[tex]f(x)=-4x+x^2+16[/tex]
We need to find f(-4), so we use x=-4:
[tex]f(-4)=-4*(-4)+(-4)^2+16[/tex]
[tex]f(-4)=16+16+16[/tex]

The area of a rectangle is greater than 60 ft. The width of the rectangle is 2x - 3 ft and the
length is 12 ft. Write an inequality and solve for x
Answer:
Inequaliy: 2x-3(12)>60
X>48
Step-by-step explanation:
Since area of a rectangle is W(L)=A
The inequality given right here including length And width and area Plugged in would be
2x-3(12)>60. (It’s >60 because the area stated in the problem said to be greater then 60 so we put a Greater then sign)
Combine like terms and solve
2x-36>60
Add 36 on both sides
2x>96
Divide 2 on both sides to isolate variable
x>48
Check:
2(50)-36>60 ( I used 50 because it’s greater then 48 and it’s a easy number to work with for just a check)
solve:
100-36>60
64>60✔️

Which of the following functions could be f(x) ?
Answer:
B. f(x) = -x^3 - x^2 + 7x - 4
Step-by-step explanation:
For this problem, we want to find the fastest-growing term in our given expressions and equate them when x is - infinite and when x is infinite to see the given trends.
For each of these equations, we will simply take the terms with the highest power and consider those. The two cases we need to consider is + infinite for x and - infinite for x. Let's check each of these equations.
Note, any value raised to an even power will be positive. Any negative value raised to an odd power will be negative.
[A] - x^4
When x is +∞ --> - (∞)^4 --> f(x) is -∞
When x is -∞ --> - (-∞)^4 --> f(x) is -∞
[B] - x^3
When x is +∞ --> - (∞)^3 --> f(x) is -∞
When x is -∞ --> - (-∞)^3 --> f(x) is ∞
[C] 2x^5
When x is +∞ --> 2(∞)^5 --> f(x) is ∞
When x is -∞ --> 2(-∞)^5 --> f(x) is -∞
[D] x^4
When x is +∞ --> (∞)^4 --> f(x) is ∞
When x is -∞ --> (-∞)^4 --> f(x) is ∞
Notice how only option B, when looking at asymptotic (fastest-growing) values, satisfies the originally given conditions for the relation of x to f(x).
