FIND THE equation of the linear function represented by the table below in slope intercept form
Answer:
y= -2x - 1
Step-by-step explanation:
Take two of the points given by the data in the table.
Using the x-values 1 and 2, they have a y-value of -3 and -5, respectively.
Therefore, we can write these out as coordinate points: (1, -3) and (2, -5).
The equation to find the slope of a line is:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]Substitute these points into this formula to find the slope of this linear function.
[tex]\displaystyle m= \frac{-5-(-3)}{2-1}[/tex]Simplify and solve for the slope m.
[tex]\displaystyle m=\frac{-2}{1} =-2[/tex]The slope of this linear function is -2. Now, we can use this slope and substitute it into the point-slope equation along with another one of the points on the function.
Point-slope equation:
[tex]y-y_1=m(x-x_1)[/tex]Substitute m = -2 and the point (1, -3) into this equation.
[tex]y-(-3)=-2(x-1)[/tex]Simplify this equation and put it into slope-intercept form: [tex]y=mx+b[/tex].
[tex]y+3=-2x+2[/tex] [tex]y=-2x-1[/tex]The equation of the linear function represented by the table is y = -2x - 1.
Answer:
y= -2x - 1
Step-by-step explanation:
Take two of the points given by the data in the table.
Using the x-values 1 and 2, they have a y-value of -3 and -5, respectively.
Therefore, we can write these out as coordinate points: (1, -3) and (2, -5).
The equation to find the slope of a line is:
Substitute these points into this formula to find the slope of this linear function.
Simplify and solve for the slope m.
The slope of this linear function is -2. Now, we can use this slope and substitute it into the point-slope equation along with another one of the points on the function.
Point-slope equation:
Substitute m = -2 and the point (1, -3) into this equation.
Simplify this equation and put it into slope-intercept form: .
The equation of the linear function represented by the table is y = -2x - 1.
How many times bigger is 315 compared to 312?
Do not include units (times bigger) in your answer.
Answer:
105/104
Step-by-step explanation:
you divide 315 divided by 312 and you get 105/104.
to check it you do 312 times 105/104 and you get 315 to be your answer! Hope this helps ;)
105/104 times the number 315 bigger than the number 312.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
The given numbers are 315 and 312.
Number of times 315 is bigger compared to 312 is
315/312
= 105/104
Hence, 105/104 times the number 315 bigger than the number 312.

What is the slope and y-intercept of y-6x=4?
Answer:
Slope: -6 Y-intercept: -4
Step-by-step explanation:
You have to put the 4 on the same side as the expression so that y-6x-4=0 so the -6x is the slope and the -4 is the y-int because of y=mx+b

rate of change y=5x+10
Answer:
5
Step-by-step explanation:
The equation [tex]y=5x+10[/tex] is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format [tex]y=mx+b[/tex], such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,
[tex]y = mx + b\\\\m=slope\\b = y-intercept.[/tex]
The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation [tex]y=5x+10[/tex] is given in the slope-intercept form, and the coefficient ([tex]m[/tex]) equals ([tex]5[/tex]), therefore the slope is ([tex]5[/tex]).

Answer:
the measure of the angle is 72
x=36
Step-by-step explanation:
we can make an algebraic equation using the info given
2x+80=152
2x=72
x=36
the measure of the angle is 72
Answer:
x = 36, the measure of the angle is 72
Step-by-step explanation:
We can see this because Angle 2x and Angle 72 are verticle angles. Based on this information we know that verticle angles are congruent to each other, meaning the are the same. So that leaves us with an equation to figure out x.
2x = 72
[tex]\frac{2x}{2}[/tex] = [tex]\frac{72}{2}[/tex]
x = 36

Find the measure of the inscribed angle.
Answer:
41°Step-by-step explanation:
Measure of the inscribed angle is half the arc measure:
x = m∠ABC = 1/2mAC x = 1/2(82°) = 41°-12 - 12x = 36 please help me with this problem due today.
Answer:
x = -4
Step-by-step explanation:
-12 -12x = 36
add 12 to each side of the equation
-12x = 48
divide both sides by -12
x = -4
Find the area of a sector with a central angle of 7.2 radians and a radius of 14 units
Please include steps
Answer:
[tex]\boxed {\boxed {\sf a= 705.6 \ units^2 }}[/tex]
Step-by-step explanation:
Since we are given the central angle in radians, we should use this formula for the sector area:
[tex]a=\frac{1}{2}r^2 \theta[/tex]
where r is the radius and θ is the angle in radians.
The radius is 14 units and the angle is 7.2 radians.
[tex]r= 14 \ units \\\theta= 7.2[/tex]
Substitute the values into the formula.
[tex]a= \frac{1}{2} (14 \ units)^2 (7.2)[/tex]
Solve the exponent.
(14 units)²= 14 units* 14 units =196 units²[tex]a=\frac{ 1}{2} (196 \ units^2)(7.2)[/tex]
[tex]a=\frac{ 1}{2}(1411.2 \ units^2)[/tex]
Multiply by 1/2 or divide by 2.
[tex]a= 705.6 \ units^2[/tex]
The area of the sector is 705.6 square units.

Joanne earned $57 in tips yesterday. Her earnings were $13 less than 7/8 of Erin's earnings.
1. Write an equation to represent Erin's earnings, x.
2. How much did Erin earn in tips?
9514 1404 393
Answer:
57 = (7/8)x -13$80Step-by-step explanation:
1. I find it convenient to use variable names that remind me what they stand for. Here, we can use "j" to represent Joanne's earnings, and "e" to represent Erin's earnings.
j = 57 . . . . . Joanne earned $57
j = (7/8)e -13 . . . . . Joanne's earnings were $13 less than 7/8 of Erin's
Substituting for j, we get one equation for Erin's earnings
57 = (7/8)e -13
Using 'x' for Erin's earnings, this is ...
57 = (7/8)x -13
__
2. We can solve the equation as follows:
70 = 7/8x . . . . . . add 13
80 = x . . . . . . . . . multiply by 8/7
Erin earned $80 in tips.
Answer:
Step-by-step explanation:
57 = ⅞x - 13
x= 70(8/7) = $80

17% - 50
9514 1404 393
Answer:
x = 21

The ratio of girls to boys in a sports club is 3: 5
There are 27 girls in the club. How many boys are there?
Answer:
45 boys
Step-by-step explanation:
The 3 part of the ratio refers to the number of girls.
Divide number of girls by 3 to find the value of one part of the ratio
27 ÷ 3 = 9 ← value of 1 part of the ratio, then
5 parts = 5 × 9 = 45 ← number of boys
Answer:
Their are 45 boys.
Step-by-step explanation:
Let's represent Girls by G,and Boys by B
so G = 27 and B = ? and G/B = 3:5 or 3/5
3 = 27
5. B
3B = 135
3. 3
B = 45
