Answer:
29.17 hours
Step-by-step explanation:
to find the zero of the function, set d to equal zero, so
0 = 70 - 2.4t
-70 = -2.4t
-70/-2.4 = t
29.17 = t

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
--5x - 9y = 33
-y - 1 = x
Step 2: Simplify systems
5x - 9y = 33
-y - 1 = x
Step 3: Solve for y
Substitute: 5(-y - 1) - 9y = 33Distribute 5: -5y - 5 - 9y = 33Combine like terms: -14y - 5 = 33Isolate y term: -14y = 38Isolate y: y = -19/7Step 4: Solve for x
Define: -y - 1 = xSubstitute: -(-19/7) - 1 = xSimplify: 19/7 - 1 = xSubtract: 12/7 = xRewrite: x = 12/7And we have our final answer!
Which equation in standard form has a graph that passes through the point (5,-2) and has a slope of 7/2
A:7x - 2y=35
B:7x - 2y=39
C:7x - 2y=-31
d:7x - 2y=-24
Answer:
B
Step-by-step explanation:
Since it's MCQ and it's LHS is all 7x - 2y, you can simply sub in (5, -2) into each option and see which one has its LHS = RHS.
7(5) - 2(-2) = 35 + 4 = 39
Hence, option B is the answer.

y=-x+12
G
J
Answer:
The equation of new line is: [tex]\mathbf{y=\frac{3}{4}x-12}[/tex]
Option H is correct.
Step-by-step explanation:
We need to write an equation for the line that is parallel to the given line [tex]y=\frac{3}{4} x-9[/tex] and point (-8,-18)
The equation of required line will in in form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope m and b y-intercept for new line.
Finding slope:
When two lines are parallel, they have the same slope.
The slope of given line can be found by comparing the equation [tex]y=\frac{3}{4} x-9[/tex] with [tex]y=mx+b[/tex]
So, m = 3/4
The slope of new line will be: [tex]m=\frac{3}{4}[/tex]
Finding y-intercept:
Using slope m = 3/4 and point (-8,-18) we can find y-intercept
[tex]y=mx+b\\-18=\frac{3}{4}(-8)+b\\-18=-6+b\\b=-18+6\\b=-12[/tex]
So, y-intercept is b=-12
The equation of new line having m = 3/4 and b=-12 is:
[tex]y=mx+b\\y=\frac{3}{4}x-12[/tex]
So, the equation of new line is: [tex]\mathbf{y=\frac{3}{4}x-12}[/tex]
Option H is correct.
pls helpp i’m confused
Answer:
D.
Step-by-step explanation:
it can't be B or C since Function A has a greater y-intercept of 2. and if you graph function A you can see that Function B has a greater rate of change
Answer:
D
Step-by-step explanation:
The rate of change for the graph is 2 so we can rule anything out that shows A has a larger rate of change. Now we look at the y intercept on the graph which is -2. The one in the function is 2 so we eliminate anything that says B has a greater y intercept this should give you the answer

Maya is interning at a law firm over the summer and is paid by the hour. Her hourly wage is $52. Write two equations represent the proportional relationship between the wages she earns (w) and the number of hours (h).
Answer:
The two equations are;
w = 52 h
and h = w/52
Step-by-step explanation:
From the question, we are told that she earns $52 in an hour
So therefore ,
W(h)= 52h
where h is the number of hours she has worked and w is the wages earned for the number of hours worked
The two equations are;
w = 52h
or w/h = 52

At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75. The sales tax is $0.98 and they leave a tip of $5.85. How much did Brianna and Naomi spend in all?
Given :
At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75.
The sales tax is $0.98 and they leave a tip of $5.85.
To Find :
How much did Brianna and Naomi spend in all.
Solution :
Total expenses, T = Food + tax + tip
T = $( 6.50+9.75) + $0.98 + $5.85
T = $( 16.25 + 0.98 + 5.85 )
T = $23.08
Therefore, total expenses is $23.08 .
Hence, this is the required solution.

3.It usually takes Claude 40 minutes driving at 48 miles per hour to go from home to work. But due to road maintenance today, Claude has to take a detour, which makes the trip 8 miles longer than usual. What is the minimum speed Claude should travel so that he can reach the destination in less than 48 minutes?
A.30 miles per hour
B.56 miles per hour
C.50 miles per hour
D.64 miles per hour
*please make sure you answer all the questions please and thank you.
Answer:
x and y can be any two numbers greater than zero such that y is also greater than x
D.no more than 45
C.50 miles per hour
Step-by-step explanation:
Let the two numbers be such that x< y because we have been given y/x>1 and x/y< 1 .
Suppose we take y= 9 and x= 3 then
9/3 > 1
3>1
Also
3/9 < 1
1/3 < 1
x and y can be any two numbers greater than zero such that y is also greater than x
2. Total weight that can be carried is 3000 pounds.
The big machine is 300 pounds. The weight that the truck can carry beside the big machine is 3000-300= 2700 pounds.
The smaller machines weigh 60 pounds
The number of smaller machines that can be carried is 2700 ÷ 60= 45 other than the big machine.
3. Total distance = Speed * time
= 48 * (40/60) = 32 miles
New distance = 32+ 8= 40 miles
New time = 48 minutes
Speed = distance / time = 40/ 48/60= 50 miles per hour
