Answer:
The correct option is;
a > 1
Step-by-step explanation:
An exponential function can be expressed in the following general form;
f(x) = b·aˣ + k
Where;
b = The coefficient term
a = The base
x = The exponent
k = The vertical shift
The characteristic of an exponential function is that it increases if a > 1
From the graph, we have;
As 'x' increases to the right of the graph, f(x) = aˣ increases (upwards), therefore, a > 1
1) 4(x-6)<2
2) 7n+19<8
3) 3(11+x)>=15
4) 4n-12<6
5) 2n+14>=1
6) 2(x+7)>=10
7) 11n-3>9
8)8x+4<=13
9)5n+16>=9
10) 4(x+2)<14
Answer:
1/7
Step-by-step explanation:
You have to multiply across the top then the bottom.
Answer:
Step-by-step explanation:
What he did at the end of the given equations is solve for x in x + 8y= 21
x = 21 - 8y Substitute that result in the top equation.
<u><em>7(21 - 8y) + 5y = 14 </em></u> is the correct step To continue Remove the brackets
147 - 56y + 5y = 14 Combine
147 - 51y = 14 Add 51y to both sides.
147 = 51y + 14 Subtract 14 from both sides.
133 = 51y divide by 51
y = 2.61 rounded.

Answer:
Step-by-step explanation:
y + 6 = -4(x + 2) is the point-slope form
y + 6 = -4x - 8
y = -4x - 14
