Answer:
<h2>y-intercept = -2 → (0, -2)</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b </em><em>- y-intercept</em>
<em />
We have the equation:
Therefore
slope: <em>m = 4</em>
y-intercept: <em>b = -2</em>
Answer:
flour $42 , bag of sugar $58
Step-by-step explanation:
let f represent flour and s represent sugar, then
7f + 5s = 584 → (1)
5f + 3s = 384 → (2)
Multiplying (1) by 3 and (2) by - 5 and adding will eliminate s
21f + 15s = 1752 → (3)
- 25f - 15s = - 1920 → (4)
Add (3) and (4) term by term to eliminate s , that is
- 4f = - 168 ( divide both sides by - 4 )
f = 42
Substitute f = 42 into either of the 2 equations and solve for s
Substituting into (1)
7(42) + 5s = 584
294 + 5s = 584 ( subtract 294 from both sides )
5s = 290 ( divide both sides by 5 )
s = 58
The cost of a bag of flour is $42 and cost of sugar is $58
Answer: 11
6*2 = 12
5*2=10
10= x - 1
x = 11
Answer:
35x^2+29x+6=0
Step-by-step explanation:
Answer:
11.81
Step-by-step explanation:
5 1/4 per 20 min (1/3 of an hour)
5.25 (5 1/4) * 3 = 15.75 pounds per hour
$0.75 earned per pound
So, 15.75 * $0.75 = $11.81
