Make the equations equal to each other to find x.
21.2x+c=5.3(4x-4.6)
Now distribute.
21.2x+c=21.2x-24.38
So c= -24.38
Answer:
C: H <u>> </u> 60
Step-by-step explanation:
H is 60 in or taller, underlined indicates that it's also 60 in, not just above it.
The initial value of a function is the y value when x = 0. For the first function, you can plug in the value of x =0 and you'll get 2/3. Function 2 has an initial value of 3 (you can look at the table). Since 3 > 2/3, function 2 has a greater initial value.
Note: I'm guessing that the table refers to Function 2.
Answer:
y = -1/7 x + 16/7
Step-by-step explanation:
Write in standard form of the equation of the line through the given points: through (2,2) and (-5,3)
Given the point (2,2) and (-5,3). The standard form of an equation passing through the points is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope
m = y2-y1/x2-x1
m = 3-2/-5-2
m = 1/-7
m = -1/7
Get the intercept. Substitute m = -1/7 and one of the point (2,2) into the expression y = mx+c
2 = -1/7(2) + c
2 = -2/7 + c
c = 2 + 2/7
c = (14+2)/7
c = 16/7
Substitute m = -1/7 and c = 16/7 into the expression y = mx+c
y = -1/7 x + 16/7
Hence the required equation is y = -1/7 x + 16/7
Answer:
C. An increase of 20%
Step-by-step explanation:
50/100 = 60/x
Cross products
50
x = 6000
Divide 50 by both sides
x = 120
60 is 120% of 50, so there is a 20% increase
Hope this helps!
