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.

Find the range of this function
Answer:
Not sure!
Step-by-step explanation:
ort each equation according to whether it has one solution, infinitely many solutions, or no solution
-3(X - 4) = – 3x + 12
4(x + 1) = 3x + 4
-2(x-3) = 2x - 6
6(x + 5) = 6x + 11
5(x-2)=5x-7
-3(X - 4) = – 3x + 12 infinite solutions
4(x + 1) = 3x + 4 one solution
-2(x-3) = 2x - 6 one solution
6(x + 5) = 6x + 11 no solution
5(x-2)=5x-7 no solution

The graph shows a function
Answer:
E, D
Step-by-step explanation:
rate of change is the slope
slope is change in y over change in x
the slope of the graph is (3/2)
E has a slope of 1/2 which is less than 3/2
D has a slope of 1 which is also less than 3/2

The value of y varies directly with x. When y = 75,x= 2. What is the value of y when
xis 2 1/4
Answer:
y = 337.5
Step-by-step explanation:
Given:
y = 75
x = 2
Solve:
Direct variation is y = kx
75 = k/2
k = 150
y = 150x
x = 2 1/4 or 2.25
y = 150(2.25)
y = 337.5 or 337 1/2
3х + 2y = 14
3х - 2y = 10
Answer:
(4, 1 )
Step-by-step explanation:
Given the 2 equations
3x + 2y = 14 → (1)
3x - 2y = 10 → (2)
Adding the 2 equations term by term, eliminates y , that is
6x = 24 ( divide both sides by 6 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
3(4) + 2y = 14
12 + 2y = 14 ( subtract 12 from both sides )
2y = 2 ( divide both sides by 2 )
y = 1
Solution is (4, 1 )

We are going to define two equations where b means bagels and m will be muffins, First equation: 10*b + 4*m = 13 Second equation: 5*b + 8*m = 14 From the second equation, we can isolate b: b = (14 - 8*m)/5 In the second equation 10*(14 - 8*m)/5 + 4*m = 13 2*(14 - 8*m) + 4*m = 13 28 - 16*m + 4*m = 13 28 -13 = 16*m - 4*m 15 = 12*m m = 15/12 = 1.25 Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8 So one bagel costs $0.8 and one muffin $1.25
Answer:
Muffins: $1.25
Bagels: $0.80

1) 32
2) 12
3) 14
4) 10
please HELP
Answer:
3) 14
Step-by-step explanation:
in the given equation replace the "g(x)" with the provided "20"
20=2(x-4) solve as usual
divide each side by 2
10=x-4
add 4 to each side
14=x
the value of x is 14
Please help me w the equation and please don’t take advantage of the points.
Answer:
y = 6x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 6 and given point (0, 4 ) ⇒ c = 4
y = 6x + 4 ← equation of line

50 POINTSSS Let f (2) represent a function.
Which descriptions match the given transformations?
Drag and drop the answers into the boxes.
For f(x - 3.5) the answer is that f(x) is translated 3.5 units right
You can figure that out by thinking that for x = 3.5 (which is 3.5 units to the right of x = 0, f(3.5 - 3.5) is the same that f(0), ... for x = 10.5 (which is 3.5 units to the right of x = 7, f(10.5 - 3.5) = f(7) ... and so for every value of x.
For 3.5 f(x) the answer is that f(x) is vertically stretched by a factor of 3.5 which you figure out from a table like this:
f(x) 3.5 f(x)
0 0
1 3.5
2 7
10 35
And from that you can see the 3.5 f(x) is horizontally compressed and vertically stretched respect to f(x).
