Slope intercept form

Mathematics
1 answer:
sergij07 [2.7K]2 years ago
4 0

Answer:

9) y=-\frac{1}{8} x+\frac{13}{8}

10) y = -1

11)  y=-\frac{5}{2}x

12) y= -\frac{4}{3}x+1

Step-by-step explanation:

Parallel lines have same slope and slopes of perpendicular lines are negative reciprocals of each other.

<u>9) through (-3, 2), parallel to   </u>y=-\frac{1}{8} x +4<u />

y-y_1=m(x-x_1)

y-2=-\frac{1}{8} (x+3)

y=-\frac{1}{8} x-\frac{3}{8} +2

<u>10) through (-5, -1), parallel to   </u>y=0<u />

y+1=0 (x+5)

y = -1

<u>11) through (2, -5), perpendicular to   </u>y= \frac{2}{5} x +5<u />

y+5=-\frac{5}{2} (x-2)

y=-\frac{5}{2}x+5-5\\y=-\frac{5}{2}x

<u>12) through (-3, 5), perpendicular to   </u>y= \frac{3}{4} x<u />

y-5=-\frac{4}{3} (x+3)

y= -\frac{4}{3}x-4 +5

y= -\frac{4}{3}x+1

Find x and y intercept and plot
set x to zero and find y
set y to zero and find x
tada, 2 points

if x=0, then y=-4
if y=0, then x=-16
we havee the points
(0,-4) and (-16,0)

or

A cross country skier reaches the 3km mark of a race in 15 min and 12 km mark 45 min later. Assuming a contrast rate find the sp
melomori [17]
To find the speed you must write S= d/t so for the first one we will chang 15 m to b so it is = 0.25h so s=3/0.25h = 12km/h an why secand is 45 m to h = 0.75h so S=d/t S =12/0.75 =16 km/h the to find the totel speed we should + the speed together so 12 + 16 = 28 km/h

Gia opened two savings accounts at two diffrent banks. One account earns an annual 3.4% simple interest, and the other earns hal
dsp73

Interest from first account is :

I_1 = \dfrac{p\times r \times t}{100}\\\\I_1 = \dfrac{509\times 3.4\times 3}{100}\\\\I_1 =\$ 51.918

Interest form second account is :

I_2 = \dfrac{p\times r\times t}{100}\\\\I_2 = \dfrac{509\times 1.7\times 3}{100}\\\\I_2 =  \$25.959

So, total interest is :

I = I_1 + I_2 \\\\I = 51.918 + 25.959\\\\I = \$77.877

Therefore, total interest is $77.877 .

WILL GIVE BRAINLIEST
Olegator [25]
The answer is A.
We can first eliminate D since it uses these (<, >) signs and the lines are shaded, indicating the points on those lines are solutions.
We can also eliminate C because the y intercept in C’s lines is 2, while in the graph, they are both 3.
Finally, we can look at both inequalities on the graph and see that the shaded areas are both underneath the line. This means that y is less than the equation for the line, eliminating B
So, the answer is A
Hope this made sense!!

If 2a+3b=12 and ab=6 find the value of 8a^3+27b^3
Alex17521 [72]
<span>A) 2a + 3b = 12
B) ab = 6 solving for a
B) a = 6 / b then we substitute this into equation A)
</span><span>A) 12 / b + 3b = 12  </span><span>multiplying this by "b"
A) 12 + 3b^2 = 12b
A) 3b^2 -12b +12= 0 dividing by "3"
A) b^2 -4b + 4 = 0
Factoring
(b-2) * (b-2) = 0
b = 2
Since b = 2 then a = 3

</span>NOW, we put these numbers into:
<span>8a^3 +27b^3 </span>
8*3*3*3 + 27*2*2*2
216 + 216
The answer is 512
