Answer:
x = 23/7
Step-by-step explanation:
7 x + 15 equals 38
7x+15 = 38
Subtract 15 from each side
7x+15-15 = 38-15
7x = 23
Divide each side by 7
7x/7 = 23/7
x = 23/7
Answer:
The intercept are the number of each of the pots used when no soil was put in the other pot.
When no soil was put in the large pots, then 120/5 = 24 small pots will be filled.
When no soil was put in the small pots, then 120/12 = 10 large pots will be filled.
Therefore, the points Labelled are (24, 0) and (0, 10)

Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
f(x) = - 0.6x² + 4.2x + 240 ← factor out - 0.6 from the first 2 terms
= - 0.6(x² - 7x) + 240
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² - 7x
f(x) = - 0.6(x² + 2(- 3.5)x + 12.25 - 12.25 ) + 240
= - 0.6 (x - 3.5)² + 7.35 + 240
= - 0.6(x - 3.5)² + 247.35
with vertex = (3.5, 247.35 )
The maximum value is the y- coordinate of the vertex
Then
f(x) = - 0.6(x - 3.5)² + 247.35 has a maximum value of 247.35
Answer:∠M in the pre-image corresponds to ∠B in the image.
Step-by-step explanation:
When we look at the figures , we can see that the three vertices B , C , D are one side as vertices to M , N ,O .
Clearly , vertex C corresponds to vertex N ( presents in the middle )
Also, point B is at the right from point C .In Figure L M N O P , vertex M is at the right from vertex N .Thus , vertex M corresponds the vertex B.
It means ∠M in the pre-image corresponds to ∠B in the image.
brain list this answer thankyou:)
