write the equation of each line in slope-intercept form slope=4 y-intercept=-5
Answers
Answer:
Y=4X-5
Step-by-step explanation:
The Slope is a positive 4 so you will already have the equation Y=4X and the y-intercept is the Y when X is at the origin. Since the y-intercept is negative you have to subtract from the slope instead of adding. Then you get Y=4X-5.

Step-by-step explanation:
(1)(1) + 5(1) - 6 = 1 + 5 - 6 = 6 - 6 = 0
(-6)(-6) + 5(-6) - 6 = 36 - 30 - 6 = 6 - 6 = 0
Answer:
B
Step-by-step explanation:
Let's solve using factoring.
x²+5x-6=0
5 is the sum of the numbers, while -6 is their product.
Think: which two numbers add up to 5, but when multiplied, equal -6?
Those numbers are -1 and 6.
Now factor the polynomial:
(x-1)(x+6)=0
split into parts:
(x-1)=0
x-1=0
x=1
(x+6)=0
x+6=0
x=-6
So B

Answers
Answer:
50m
Step-by-step explanation:
Calculation for the height of the building
First step:
Let x represent the building height
Second step:
100m/8m = x/4
Third step is to Cross multiply:
100m(4) = 8x

Tim rolls a number cube labeled 1 through 6 and flips a coin. Which is the
probability that Tim rolls a number greater than 3 and flips tails?
Answers
There are 3 numbers on the cube greater than 3 ( 4, 5, & 6)
This means he has a 3/6 = 1/2 chance of doing that.
He has a 1/2 chance of getting tails on the coin.
The probability of doing both would be the probability of the cube roll x the probability of the coin toss:
1/2 x 1/2= 1/4
The answer is 1/4

b. In the diagram, the measure of angle PQR = 130°, the measure of angle RQS = 84°, and the measure of angle TSR = 121°. Find the other angle measures in the diagram.
Answers
First off, we can see already that there are congruent symbols in the diagram (the single and double red lines correspond to the other one that looks alike to it)
Measure QRS is like measure QPT and since QRS = 84°, then QPT also equals 84°
Measure TSR is like measure STP and since TSR = 121°, then STP also equals 121°

m∠1 = m∠6 =
m∠2 = m∠7 =
m∠3 = m∠8 =
m∠4 = m∠9 =
Answers
Answer:
See below
Step-by-step explanation:
Kites have perpendicular diagonals, two pairs of congruent angles and sides.
Angles 1, 2, 3, 4 are all right angles∠6 and 37 are congruent, ∠5 and 43 are congruent, ∠7 and ∠9 congruent, ∠8 and ∠10 are congruentRequired measures:
m∠1 = 90 ° m∠6 = 37°m∠2 = 90 ° m∠7 = 90° - 37° = 53° m∠3 = 90 ° m∠8 = 90° - 43° = 47 ° m∠4 = 90 ° m∠9 = 53°m∠5 = 43 ° m∠10 = 47 °The angles are m∠1 =m∠2 =m∠3 =m∠4 = 90 degrees.
m∠9=m∠7 =m∠8= m∠10 = 53 degrees.
m∠5 = m∠6 =37 degrees
Let us find the angles.
m∠1 , m∠2, m∠3 and m∠4 are right angles.
m∠1 =m∠2 =m∠3 =m∠4 = 90 degrees.
Now let us find m∠9.
By angle sum property, the sum of three angles is 180 degrees.
m∠1 + 37 + m∠9 =180
37+90+m∠9=180
127+m∠9=180
m∠9=180-127
m∠9=53
m∠9=m∠7 = 53 degrees.
Now let us find m∠6.
53+90+m∠6=180
143+m∠6=180
m∠6=37 degrees.
m∠5 = 37 degrees as it is congruent to m∠6.
Now let us find m∠8.
m∠8 + 90+ 37=180
m∠8 +127=180
m∠8 =53 degrees.
m∠10 = 53 degrees.

How does graphing help you solve a system of linear equations? i need the answer asap please

In the function y = x, if y = -8, what is x equal to?
Answers
Answer:
x = -8
Step-by-step explanation:
[tex]y =x[/tex]
If y = -8 — Substitute y = -8 in the equation.
[tex] - 8 = x[/tex]
Therefore, our x is -8 when y = -8
Answer:
x=-8
Step-by-step explanation:
Let's solve your system by substitution.
y=x; y=−8
Rewrite equations:
y=−8; y=x
Step: Solve y=−8 for y:
y=−8
Step: Substitute −8 for y in y=x:
y=x
−8=x
−8+−x=x+−x(Add -x to both sides)
−x−8=0
−x−8+8=0+8(Add 8 to both sides)
−x=8
-x/-1 = 8/-1
x=-8

Phil Lanthropist won a great deal of money in a contest. He gave 20% of his winnings to his parents, 25% of the remaining money to his children, and the remaining $900,000 to his favorite charity. What was the total number of dollars that Phil won?
Answers
Answer:
$1,636,363.64
Step-by-step explanation:
let x = total amount of money received
the total amount he received is 100%
Percent remaining after giving a percent of the money to family = 100% - 20% - 25% = 55%
This means that 55% of x = $900,000
To find the value of x, divide both sides by 55% or 0.55
x = $900,000 / 0.55 = $1,636,363.64

On a softball field, home plate is 43 feet from the pitcher's mound. A ball is hit at an angle of 27° east of the pitcher's mound. The ball travels 162 feet before it is caught by an outfielder. A triangle is drawn on a baseball field. A point is at home plate, another point is at the pitcher apostrophe s mound, and another point is at an outfielder. The distance from home plate to the pitcher is 43 feet. The distance from home plate to the outfielder is 162 feet. The angle between the 2 sides is 27 degrees. Law of cosines: How far must the outfielder throw the ball to return it to the pitcher? Round to the nearest foot. 112 feet 125 feet 145 feet 156 feet
Answers
Answer:
c = 125 f
Step-by-step explanation:
Let´s call points A ( home plate ) B (pitcher´s place ) and C ( outfielder place)
these three points form a triangle in which according to cosine law, one side of a triangle c can be calculated by the equation:
c² = a² + b² - 2a*b*cos∡a,b
a and b are the other sides of the triangle and ∡a,b is the angle between sides a and b
All distances are in feet then the distance between outfielder and pitcher (c) is in feet:
c² = (43)² + ( 162)² - 2*(43)*(162)*cos 27° cos 27° = 0,891
c² = 1849 + 26244 - 12413,4
c² = 15679,6
c = √15679,6
c = 125 f

At the local dairy farm, Kareem buys a 32-oz container of yogurt for $2.56. Jonah buys a 6-oz container of yogurt for $0.48. Are the cost, y, in dollars and the amount of yogurt, x, proportional? Explain. Write an equation to represent this relationship.
Answers
Answer:
Yes, the cost y in dollars and the amount of yogurt are proportional.
The equation is: y = 0.08x
Step-by-step explanation:
1. If y varies directly as x, you can write it as following: y = kx
Where k is the constant of proportionality.
2. Let's calculate the value of the constant of proportionality. If y = 2.56 and x = 32, you have:
y = kx
k = y/x
k = 2.56/32
k = 0.08
3. Then, the equation is: y = 0.08
4. Let's verify if they are directly proportional. Substitute which is the amount of yogurt bought by Jonah. The result must be $0,48:
y = 0.08 (6)
y = 0.48
5. They are directly proportional.
