Answer:
-7/2
Step-by-step explanation:
the slope is the number multiplying x, so in this case it would be -7/2
Remember the formula is y=mx+b where m is slope and b is the y-intercept.
Answer:
B). (-4, 5)
Step-by-step explanation:
-2x – 3y = -7 | ×2 |
-4x + y = 21 | ×1 |
-4x – 6y = -14
-4x + y = 21
____________ --
-7y = -35
y = -35/-7
y = 5
-4x + y = 21
-4x + 5 = 21
-4x = 21 - 5
-4x = 16
x = 16/-4
x = -4
Answer:
Step-by-step explanation:
<u>According to intersecting secants theorem we have the following equation:</u>
- 3x*(3x + 5x) = 2x*(2x + kx)
<u>Solve it for k:</u>
- 3x*8x = 4x² + 2kx²
- 24x² = (4 + 2k)x²
- 24 = 4 + 2k
- 20 = 2k
- k = 10
A fraction you are dividing while a decimal is considered as a number
Answer:
73 markers
Step-by-step explanation:
let b = blue markers
black markers = b+5
red markers = 4* black markers
= 4 * (b+5)
= 4b+20
The total markers is blue + black + red
b + b+5 + 4b+20 = 6b+25
We know she has 8 blue markers
black markers = b+5 = 8+5 = 13
red markers = 4b +20 = 4*8 +20 = 32+20 = 52
The total markers =6b+25= 6(8) + 25 = 48+25 = 73
