Answer:
I think the first one
Step-by-step explanation:
because the first equation is written correctly
The ratio is 4:9 to get from 4 to 36, you need to multiply 4 by 9. Now you need to do the same to 9. multiply 9x9 to get 81. The new ratio is 36:81, with 3 point tries being 81.
Hope this helped :)
Sloope intercept form is
y=mx+b
m=slope
b=y intercept =where the line passes through the y axis
we are given
line M has slope of 1 and passes through y axis at -2 (y intercept=-2)
equaton is therefor y=1x-2 or y=x-2
line N has slope of 1 and passes through y axis at -2 (y intercept=-2)
equaton is therefor y=1x-2 or y=x-2
compare
line M: y=x-2
line N: y=x-2
they are the same line and lines extend infinitely so therefor there are infinite number of solutions
Answer:
<h3>
x-intercepts: (-7, 0) and (7, 0)</h3><h3>
y-intercept: (0, -49)</h3>
Step-by-step explanation:
x-intercepts: f(x) = 0
x² - 49 = 0
x² = 49
x = -7 ∨ x = 7
Points: (-7, 0) and (7, 0)
y-intecept: y = f(0)
f(0) = 0² - 49 = -49
Point: (0, -49)
