Just plug in the numbers! it gives you the slope and the y-intercept right in the question so no math required. The slope is -6, and the y-int is 3, therefore y = -6x + 3 is the answer
Answer:
y- intercept = - 13 , x- intercept =
Step-by-step explanation:
To find the y- intercept, substitute x = 0 into the equation and solve for y
y = 5(0) - 13 = 0 - 13 = - 13 ← y- intercept
To find the x- intercept substitute y = 0 into the equation and solve for x
0 = 5x - 13 ( add 13 to both sides )
13 = 5x ( divide both sides by 5 )
= x
x- intercept = = 2 = 2.6
Answer:
D = -6, E = -8 , F = 0
Step-by-step explanation:
standard form =
now, when circle passes through (3,-1);
⇒
⇒ ...............( equation 1)
when circle passes through (-2,4);
⇒
⇒ ...............( equation 2)
when circle passes through (6,8);
⇒
⇒ ................( equation 3)
by solving these 3 equations , we get;
D = -6, E = -8, F = 0
hence,
standard form =
=
Answer:
84.85
Step-by-step explanation:
1.5[3(14.5+7)-3]-7.4
1.5[3*21.5-3]-7.4
1.5*61.5-7.4
=84.85
Answer:
Yes, her calculation is correct. The value of 40% of 75 is 30.
Step-by-step explanation:
The value of 40% of 75 is
The value of of 75 is
From the above calculation it is noticed that the value of 40% of 75 and of 75 are same, therefore the calculation is correct and the value of 40% of 75 is 30.
