Answer:
a) x = -3
b) y = (28/27)x -27
Step-by-step explanation:
a) College street has a slope of 0, so is a horizontal line. 2nd Ave is perpendicular, so is a vertical line, described by an equation of the form ...
x = constant
For 2nd Ave to intersect the point (-3, 1), the constant must match that x-coordinate. The equation is ...
x = -3
__
b) Since Ace Rd is perpendicular to Davidson St, its slope will be the opposite reciprocal of the slope of Davidson St. The slope of Ace Rd is ...
m = -1/(-27/28) = 28/27
Using the point-slope equation for a line, we can model Ace Rd as ...
y -y1 = m(x -x1)
y -1 = (28/27)(x -27)
y = (28/27)x -27
Answer:
width equals fifteen times one hundred sixty five
is that right or is that ok or good enough?? sorry if i am wrong....
We know opposite angles in the parallelogram is congruent:
let x to be the unknown angle:
360=2(110)+2x
360=220+2x
140=2x
x=70
ECF is also 110 because of parallel lines and corresponding angles:
110+x+y=180
110+30+y=180
y=40
so DAE is 40
Pretty sure it’s -12 but I could be reading the question wrong since it’s pretty late
Answer:
B
Step-by-step explanation:
<em>a/b × d/c = a×d / b×</em><em>c</em>
Multiply the numerators 1st.
x × x = x^2
Next is the Denominator.
x+3 × x+2
now try to multiply each term of the 1st expression with the 2nd.
x × x + x × 2 + 3 × x + 6
x^2 + 2x + 3x + 6
x^2 + 5x + 6
Write the numerator & denominator in their respective places.
x^2 / x^2 + 5x + 6
