Answer:
Step-by-step explanation:
Analyze the function:
f(x)=
+19.8x+58
To find the x-intercept, set y=0:
+ 
+ 58 = 0
Convert decimal to fraction:
+ 
x+58=0
Reduce the fraction:
+ x + 58 = 0
Multiply both sides of the equation by the common denominator:
×+
× + 58 × 10 = 0 × 10
Reduce the fractions:
+ 58 × 10 = 0 × 10
Calculate the product or quotient:
-49
Make the leading coefficient positive:
49
Identify the coefficients:
a = 49, b = -198, c = -580
Substitute into x = 
or
Combine the results:
Answer:
hmm bro it's kinda blurry can u retake the pic? i will help u to solve it
1 m = 100 cm....so 2.5 m = (2.5 * 100) = 250 cm
a = 1st shelf
b = 2nd
c = 3rd
d = 4th
a + b + c + d = 250
b = 2a + 18
c = a - 12
d = a + 4
a + (2a + 18) + (a - 12) + (a + 4) = 250
5a + 10 = 250
5a = 250 - 10
5a = 240
a = 240/5
a = 48 cm <== 1st shelf
b = 2a + 18 = 2(48) + 18 = 114 cm <== 2nd shelf
c = a - 12 = 48 - 12 = 36 cm <== 3rd shelf
d = a + 4 = 48 + 4 = 52 cm <== 4th shelf
so 2nd shelf is 114 cm
Answer:
-3x - 9y = 36
If x = 0
Step-by-step explanation:
1. Plug 0 to x:
-3(0) - 9y = 36
2. Simplify
0 - 9y = 36
3. Cross out the 0 to make the question faster to solve, which now you are left with:
-9y = 36
4. Divide both sides by -9:
-9y/-9 = 36/-9
5. Simplify:
y = -4 <--------Answer
Hope this Helped!!!!!
