Answer:
y = 2x + 12
Step-by-step explanation:
You can check this by plugging any of the values from the table into the equation. You can find the answer by finding the slope and then using that to find the y-intercept.
y2-y1/x2-x1
16-14/2-1 = 2/1 = 2. So our slope equals 2.
If we set x = 0 to find our y-intercept, and we know that we have a slope of 2 we can subtract 2 from 14 to get the y-intercept.
14-2 = 12. --> (0, 12) which is true because we know that the slope is 2.
Answer:
y=60° b=60°
Step-by-step explanation:
the sum of all degrees of interior triangle is 180
in the first one, 30° and 90° have been given.(that small square represent 90°)
so 180°-90°-30°=60°
in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°
Answer:
$51.50
Step-by-step explanation:
<em>Let the amount that Phil give to her sister be
</em>
<em><u>After Phil's sister pays her debt of 10, Phil and her sister should have EQUAL amount. </u></em>So we can write the equation as:

Now solving this for x, we have:

Hence, Phil must give $51.50 to her sister.
3.6 / 0.2 = 18 liter glasses :))
A) D + Q = 124
B) .10D + .25Q = 20.50
Multiply B) by -4
B) -.40D + -Q = -82.00 then add to A)
A) D + Q = 124
.60 D = 42
D = 70 Dimes
Q = 54 Quarters
A roll of quarters = $10 = 40 Quarters so there will be 14 "extra" quarters.
