Answer:
Y=1
Step-by-step explanation:
Plug in 3 for x
y=2(3)²-4(3)-5
y=18-12-5
y=1
Answer:
width 5
length 7
Step-by-step explanation:
W * L = 35
L = 4 * W - 13
W * (4W-13) = 35
4 W^2 - 13 W - 35 = 0
delta = 169 + 4*4*35 = 729 = 27^2
W = (13 + 27) / 8 = 5 (its the only solution since 13 - 27 is less than 0 which makes no sense)
L = 4 * 5 - 13 = 7
Answer:
Measure of angle ADC is 70°
Step-by-step explanation:
So, we know that the overarcing angle BDA equals 110°. And then, we have these two equations that split up this overarcing angle. To solve for x, all we need to do is say is that the sum of these two equations are equal to 110°
2x+10+3x+25=110
Combine like terms
5x+35=110
Subtract 35 from both sides
5x=75
Divide by 5 on both sides
x=15
Now, to find the measure of angle ADC, simply plug 15 in for x on that equation:
3(15)+25
So, the measure of angle ADC is 70°
Answer: About x=1.122. Exactly x=1.121723
Step-by-step explanation:
Calculator work.
Step 1: Simplify both sides of the equation.
1.5(12x−10)=0.33(9+6x)
(1.5)(12x)+(1.5)(−10)=(0.33)(9)+(0.33)(6x)(Distribute)
18x+−15=2.97+1.98x
18x−15=1.98x+2.97
Step 2: Subtract 1.98x from both sides.
18x−15−1.98x=1.98x+2.97−1.98x
16.02x−15=2.97
Step 3: Add 15 to both sides.
16.02x−15+15=2.97+15
16.02x=17.97
Step 4: Divide both sides by 16.02.
16.02x/16.02=17.97/16.02
x=1.121723
