Answer:
(c) BK = 65
Step-by-step explanation:
Corresponding sides are proportional in similar triangles, so ...
ZT/ZQ = KF/KB
27/(2x +7) = 45/(4x+1)
27(4x+1) = 45(2x +7) . . . cross-multiply
3(4x +1) = 5(2x +7) . . . . divide by 9
12x +3 = 10x +35 . . . . . eliminate parentheses
2x = 32 . . . . . . . . . . . . . subtract 10x+3
x = 16 . . . . . divide by 2
Then the length of BK is ...
BK = 4x+1 = 4·16 +1
BK = 65
Answer:
a. y = 3 × 0 + 15
y= 0+15
y= 15
Step-by-step explanation:
Subtitute the variables into the place they are denoted with and solve it
And the place where the equation will cross the y axis is just the last numbers i.e. 15 and 3z which is 6
Answer:
The x-intercept is 5.
Some people prefer you right it as a point (5,0).
Step-by-step explanation:
The x-intercept can be found by setting y=0 and solving for x.
Just like to find the y-intercept you can set x=0 and solve for y.
Let's find the x-intercept.
So we will set y=0 and solve for x:
3x-9y=15
3x-9(0)=15
3x-0 =15
3x =15
Divide both sides by 3:
x =15/3
x =5
So the x-intercept is (5,0).
7 x 6 is 42 hope that helps
