Answer:
infinitely many solutions
Step-by-step explanation:
1) distribute 9 to each term inside parenthesis on left side of equation
18x+90=2(9x+45)
2)now distribute 2
18x+90=18x+90
these equations are exactly the same! this means that this equation has infinitely many solutions
Hope this helps!
Step-by-step explanation:
Kym teaches sixth grade students in an urban school where most of the families in the community live below the poverty line. Each year the majority of the students in her school fail the statewide tests. Kym follows school district teaching guides and typically uses direct instruction in her Language Arts and Social Studies classes. The classroom assessments are designed to mirror those on the statewide tests so the students become familiar with the assessment format.
height=x
length=20-2(what u cut out)=20-2x
width=30-2(what u cut out)=30-2x
so v(x)=l*w*h=x(20-2x)(30-2x)
b) (0,10)
Answer:
a) t-4 = 3 (i - 1/4h) = h = 3i - 3 3/4h
= t = -0.75
= h = 4
b) 3.30am = 1 inch.
Step-by-step explanation:
a) formula for point slope form = y - y1 = m(x-x1)
a) t-4 = 3(i - 1/4h) converts to t-4 = 3i - 3/4h = t = 3i- 3 3/4
x = - 0.75 y = 4 = t= -0.75 and h = 4
b) 12.15am = 4 inches
1.15am = 3.25 inches
2.15am = 2.5 inches
3.15am = 1.75inches
3.30 = 1 inches
3.15 + 15mins = 1 inch
