Answer:
y=-2x+11
Step-by-step explanation:
Slope-intercept form is y=mx+b.
Slope is rise/run, which is y2-y1/x2-x1. Using these points, that's (13-5)/(-1-3). This is 8/-4, or -2.
You can plug this into y=mx+b to get y=-2x+b.
To solve for b, you can use one of the original points and plug it back into the formula:
y=-2x+b
5=-2(3)+b
5=-6+b
b=11
So, putting it all together, you get y=-2x+11.
Let m = slope
m = (13 - 5)/(-1 - 3)
m = 8/-4
m = -2
Now use the point-slope formula.
Here is the formula: y - y_1 = m(x - x_1).
y - 5 = -2(x - 3)
y - 5 = -2x + 6
y = -2x + 6 + 5
y = -2x + 11
Done.

how many solutions will this quadratic equation x^2+8x+16 has?
Answers
Answer:
one solution
Step-by-step explanation:
to find out how many solutions a quadratic equation (with the equation ax²+bx+c) will have, we need to find the discriminant, which is b²-4ac
first, we can label the coefficients as a, b, and c
a=1 (1 is in front of x²)
b=8
c=16
now substitute into the formula
D=(8)²-4(1*16)
D=64-64
D=0
the discriminant is 0
when the discriminant is 0, that means the quadratic equation only has one solution.
Hope this helps!

A full tub of water weighs 3 1/8 pounds. If the tub is filled up only 1/7 full how much would it weigh?
Answers
Answer:
[tex]\frac{25}{56}[/tex] pounds
Step-by-step explanation:
By using unitary method,
∵ 1 full tub of water weighs = [tex]3\frac{1}{8}[/tex] pounds
∴ [tex]\frac{1}{7}[/tex] of a water tub will weigh = [tex]3\frac{1}{8}\times \frac{1}{7}[/tex]
= [tex]\frac{(24+1)}{8}\times \frac{1}{7}[/tex]
= [tex]\frac{25}{56}[/tex] pounds
Therefore, water filled in [tex]\frac{1}{7}[/tex]th part of the tub will weigh [tex]\frac{25}{56}[/tex] pounds.
The weight of the tub if filled up to 1/7 full is 25/56 pounds
How to find product of fractionGiven:
Full weight of tub = 31/8 poundsIf filled halfway:
= 1/7 × 3 1/8
= 1/7 × 25/8
= (1 × 25) / (7 × 8)
= 25/56 pounds
Therefore, the weight of the tub if filled to 1/7 of the capacity is 25/56 pounds

Jean can pack 5 cartons in 15 minutes. Which expression can be used to show the number of cartons Jean can pack in x hours? Group of answer choices
Answers
Answer: 20x
Step-by-step explanation:
First we should note that 60 minutes = 1 hour. Therefore, 15 minutes = 15/60 = 1/4 hour
Since Jean can pack 5 cartons in 1/4 hours, the number of carton that he can pack in one hour will be:
= 5 ÷ 1/4
= 5 × 4
= 20 cartons.
Therefore, to get the number of cartons that Jean can pack in x hours, we will multiply 20 by x. This will be:
= 20 × x
= 20x

Step-by-step explanation:
Mr. Jackson has just finished building his treehouse and still needs to buy a ladder to be attached to the ledge of the treehouse and anchored at a point on the ground, as modeled below. Mr. Jackson is standing 1.3 meters from the stilt supporting the treehouse. This is the point on the ground where he has decided to anchor the ladder. The angle of elevation from his eye level to the bottom of the treehouse is 56 degrees. Mr. Jackson's eye level is 1.5 meters above the ground. Determine and state the minimum length of a ladder, to the nearest tenth of a meter, that Mr. Jackson will need to buy for his treehouse. (do not round until the very end)
Answers
Answer:
The length of the ladder Mr. Jackson will need to buy for his treehouse is approximately 3.7 meters
Step-by-step explanation:
The parameters given in the question are;
The horizontal distance from the point Mr. Jackson has decided to anchor the ladder to the the stilt supporting the tree house = 1.3 meters
The angle of elevation from Mr. Jackson's eye level to the bottom of the treehouse = 56°
The height of Mr. Jackson's eye level from the ground = 1.5 meters
From the question, we can draw the geometry of the ladder attached to the treehouse using Microsoft Visio as shown in the attached diagram
From the diagram, by trigonometric ratios, we have;
tan(56°) = a/1.3
∴ a = 1.3 × tan(56°) ≈ 1.927
By Pythagoras' theorem, we have;
The length of the ladder = √((a + b)² + 1.3²)
From the drawing, b = 1.5 m
Therefore, we have
The length of the ladder = √((1.927 + 1.5)² + 1.3²) ≈ 3.6653
The length of the ladder without rounding = √((1.3 × tan(56°) + 1.5)² + 1.3²) = 3.66559488352
∴ The length of the ladder given to the nearest tenth of a meter ≈ 3.7 m
The length of the ladder Mr. Jackson will need to buy for his treehouse ≈ 3.7 m.
