Answer:
x-intercepts are (-3,0) and (-4,0).
y-intercept is (0,12).
Step-by-step explanation:
x-intercept is a point where the value of y is zero.
y-intercept is a point where the value of x is zero.
Given equation is :
y=x²+7x+12
put x=0 in given equation to find y-intercept.
y=(0)²+7(0)+12
y= 0+0+12
y= 12
hence, y-intercept is (0,12).
put y=0 in given equation to find x-intercept.
0=x²+7x+12
split the middle term of above equation to make the equation into two groups such that the sum of two numbers should be 7 and their product be 12.
x²+3x+4x+12=0
making two groups and taking common out:
x(x+3)+4(x+3)=0
take (x+3) common,
(x+3)(x+4)=0
x+3=0 or x+4=0
x=-3 or x=-4
hence, x-intercepts are (-3,0) and (-4,0).
The question ask to solve and compute the said problem if x = 2 and the equation is y=0.7x. In that alone, the value of y is 1.4 so it means its solution, by means of representing it coordinate, it should be (2,1.4). I hope you are satisfied with my answer and feel free to ask for more
Answer:
C
Step-by-step explanation:
You can reason your way through this without a calculator:
A: the absolute function turns everything positive, then you can see that 5/6 cannot be larger than 1 5/6
B: Realizing that √25=5, √18 cannot be larger than 5
C: 5.6x10³ means shifting to the left 3 positions: 5600 > 1000 so this one is true.
D: A negative number is always smaller than a positive number.
Answer:
$8475
Step-by-step explanation:
13% of 7500 is 975 so i then added 975 7,500 and got $8,475
