This table models a linear function.
x -8 -4 4 8
y -1 0 2 3
Enter the coordinates of the y-intercept in the boxes.
Answer:
[tex](x,y) = (0,1)[/tex]
Step-by-step explanation:
Given
The above table
Required
Determine the coordinates of the y intercept
Represent points on the table as:
[tex](x_1,y_1) = (4,2)[/tex]
[tex](x_2,y_2) = (8,3)[/tex]
First, calculate slope (m):
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{3-2}{8 - 4}[/tex]
[tex]m = \frac{1}{4}[/tex]
For y intercept, the following coordinate point exist:
[tex](x_3,y_3) = (0,y)[/tex]
Because x = 0 at y intercept
Calculate the slope as:
[tex]m = \frac{y_3 - y_1}{x_3 - x_1}[/tex]
The equation becomes
[tex]\frac{1}{4} = \frac{y - 2}{0 - 4}[/tex]
[tex]\frac{1}{4} = \frac{y - 2}{- 4}[/tex]
Cross Multiply:
[tex]4(y-2) = -4 * 1[/tex]
Divide through by 4
[tex]y - 2 = -1 * 1[/tex]
[tex]y - 2 = -1[/tex]
Make y the subject:
[tex]y = 2-1[/tex]
[tex]y = 1[/tex]
Hence, the coordinates of the y intercept is:
[tex](x,y) = (0,1)[/tex]

The fastest time for completing an obstacle course is 218 seconds. Artest completed the first half of the course in 95 seconds. It took him 124 seconds to finish the second half. a. What is Artest's total time? b. How does his time compare to the fastest time?
Answer:
219 Seconds ; He was 1 second faster
Step-by-step explanation:
Two halfs equal one whole, meaning both of the times added will equal the full time he took:
95+124=219
219 Seconds
He was 1 second faster because:
219-218=1
1. Identify the domain of the graphed function
Contestants in the Run-and-Bike-a-thon
run for a specified length of time, then bike for a specified length of time. Jason ran at an average speed of 5.2 mi/h
and biked at an average speed of 20.8 mi/h,
going a total of 14.4 miles. Seth ran at an average speed of 10.4 mi/h and biked at an average speed of 18.2 mi/h,
going a total of 18 miles. For how long do contestants run and for how long do they bike? Round to the nearest hundredth if necessary.
Contestants run__hour and bike___hour.
Answer:
They ran for 0.923 hrs and biked for 0.46 hrs
Step-by-step explanation:
First thing to do is write down the inequality of the question
5.2x + 20.8y = 14.4
10.4x + 18.2y = 18
Multiplying the whole equation by 10, so as to eliminate the decimal places, we have.
52x + 208y = 144
104x + 182y = 180
Multiplying the first equation by 2, we have
104x + 416y = 288, next we solve it simultaneously with the second equation
104x + 416y = 288
104x + 182y = 180
Subtract 2 from 1, and we have..
416y - 182y = 288 - 180
234y = 108
y = 0.46
Now, we go back and substitute for y in the earlier equation, so that
52x + 208(0.46) = 144
52x + 95.68 = 144
52x = 144 - 95.68
52x = 48.32
x = 48.32/52
x = 0.929
A type of rope weighs 4 ounces per inch.
What does it weigh in pounds per foot?
0.25 pounds per foot
64 pounds per foot
0.02 pounds per foot
3 pounds per foot
Answer:
Answer:3 pounds per foot
The required weight of the rope in pounds per foot is given as 3 pounds per foot.
Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.
here,
As of the conversion of the unit,
45 ounces = 0.25 pound
12 inch = 1 foot
Weigh of rope, in 12-inch rope,
= 12 × 0.25
= 3 pounds per foot
Thus, the required weight of the rope in pounds per foot is given as 3 pounds per foot.

What is the midpoint of the segment shown below?
Answer:
We conclude that the midpoint of the segment is:
[tex]\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]Hence, option D is correct.
Step-by-step explanation:
Given the points
(-6, -1)(-3, 4)Finding the midpoint of the segment using the formula
[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(-6,\:-1\right)[/tex]
so
[tex]=\left(\frac{-6-3}{2},\:\frac{-1+4}{2}\right)[/tex]
[tex]=\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]
Therefore, we conclude that the midpoint of the segment is:
[tex]\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]Hence, option D is correct.

am I right to think that this is multiplication
if not then use the 2 numbers and their sign whatever it may be.
There are 1200 students at a school.
Each student has either a packed lunch or a school dinner.
62% of the students have school dinners.
55% of the students are girls.
45% of the girls have packed lunches.
How many boys have school dinners?
You must show all your working.
Answer:
The number of boys that have school dinners is 381.
Step-by-step explanation:
First, we need to find how many students have school dinners:
[tex] SD = 1200*0.62 = 744 [/tex]
The percent of girls that have school dinners:
[tex] \%SD_{g} = 100\% - 45\% = 55\% [/tex]
Now, we need to find the number of boys (b) and girls (g) at a school:
[tex] g = 1200*0.55 = 660 [/tex]
[tex]b=1200 - 660 = 540[/tex]
Hence. the percent of boys that have school dinners is given by:
[tex] SD = g*\%SD_{g} + b*\%SD_{b} [/tex]
[tex]\%SD_{b} = \frac{SD - g*\%SD_{g}}{b} = \frac{744 - 660*0.55}{540} = 0.706[/tex]
[tex] \%SD_{b} = 70.6\% [/tex]
Finally, the number of boys that have school dinners is:
[tex]B = 540*0.706 = 381[/tex]
Therefore, the number of boys that have school dinners is 381.

the height of a shed is 6cm. a ladder leans agaisnt the shed with its base 4.5 m away, and its top just reaching the roof. what is the length of the ladder?
Answer:
4.5m
Step-by-step explanation:
The set up is a right angles triangle
Height of the shed = opposite side = 6cm
Distance of the ladder from the shed = adjacent = 4.5m
Lenght of the ladder = Hypotenuse = x
Using pythegoras theorem to find the length of the ladder
hyp² = opp²+adj²
hyp² = 0.06² + 4.5²
hyp²= 0.0036+20.25
hyp² = 20.2536
hyp = √20.2536
hyp = 4.50m
Hence the length of the ladder is 4.5m

Function NotationStep-by-step explanation:
Step 1: Define
h(t) = -20 + 11t
h(11) is t = 11
Step 2: Evaluate
Substitute: h(11) = -20 + 11(11)Multiply: h(11) = -20 + 121Add: h(11) = 101determine the value of p if one root of equation x^2+px+1=0 is the square of other.
Answer:
-2
Step-by-step explanation:
Given equation is x²+px+1=0
comparing the equation with ax²+bx+c=0
then a=1,b=p,c=1
let the roots one root of the equation be A then
by question, another root is A².
we know
A(ALPHA)+A²(beta)=-b/a
A+A²=-p/1
A+A²=-p......1
again
A*A²=c/a
A³=1/1
A³=1
A=1
Now,
substituting A=1 in equation 1
1+1²=-p
2=-p
Therefore p=-2.

Please answer this 7/8 - 6/7
Answer: [tex]\frac{1}{56}[/tex].
Step-by-step explanation:
First, we need to find a common denominator. Which is 56.
So the fraction for 7/8 will be [tex]\frac{49}{56}[/tex] and 6/7 will be [tex]\frac{48}{56}[/tex].
[tex]\frac{49}{56} - \frac{48}{56} = \frac{1}{56}[/tex].

Please help it’s a slope from graph
Answer:
[tex]\displaystyle m=1[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Find points from graph.
Point (-1, 0)
Point (0, 1)
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
Substitute [SF]: [tex]\displaystyle m=\frac{1-0}{0+1}[/tex][Frac] Subtract/Add: [tex]\displaystyle m=\frac{1}{1}[/tex][Frac] Divide: [tex]\displaystyle m=1[/tex]Answer:
1
Step-by-step explanation:
To do this you just need to know the slope equation y2 - y1 over x2- x1 so if you plug in 2 coordinates you can do (0,1) and (-1,0) and when you plug it into the formula you get 1/1 which is 1 so the slope is 1
