Answer:
12 dimes and 4 quarters
Step-by-step explanation:
If a quarter is 25 cents and a dime is 10 cents then:
There are at least 8 dimes, so we have at least 80 cents
And we know there is only 8 more dimes than quarters so the ratio 12 dimes: 4 quarters tells us that this expression is correct
Answer:
<h2>8. slope = 2</h2><h2>9. y-intercept = -3</h2><h2>10. in the attachment</h2>
Step-by-step explanation:
The slope-intercept form y = mx + b
m - slope
b - y-intercept → (0, b)
We have the equation
y - 2x = -3 <em>add 2x to both sides</em>
y = 2x - 3
slope m = 2
y-intercept b = -3
We need two points to draw a graph of this linear function.
One is y-intercept (0, -3). The second one is calculated by choosing any value of x and put it to the equation:
for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1).
Answer:
y=-5
Step-by-step explanation:
-10/2=2y/2
-5=y
y=-5
Answer:
A -6 < x ≤ -3
Step-by-step explanation:
21 ≤ - 3(x - 4) < 30
Divide all parts by -3. Remember that flips the inequalities
21/-3 ≥ - 3/-3 (x - 4) > 30/-3
-7 ≥ (x - 4) > -10
Add 4 to all sides
-7+4 ≥ x - 4+4 > -10+4
-3 ≥ x > -6
Rearranging the order
-6 < x ≤ -3
