Answer:
k = -10.5
Step-by-step explanation:
k + 7.5 = -13
Subtract 7.5 from both sides
k + 7.5 - 7.5 = -13 - 7.5
k = -20.5
Write an equation of the line in slope-intercept form. (0,2) (3,3)
i dont see an image
Step-by-step explanation:
Answer: y = 1/3x +2
Step-by-step explanation:
The slope-intercept form of an equation looks like this:
y=mx+b
The m stands for the slope and the b stands for the y-intercept. We need two points on the line to write out this equation.
We have the two points you entered, so let's start by getting the slope. (1/3)
Now that we have the slope, we can plug it into our equation: y = 1/3x+b
To get b, our y-intercept, we just need to plug in one of the points you entered and solve. Now that we have both our m and b values, we can plug them in to get our equation: Y= 1/3x+2
Hope it helps.

This question is essentially asking one to find the vertex of the parabola formed by the given equation. One could plot the equation, but it would be far more efficient to complete the square. Completing the square of an equation is a process by which a person converts the equation of a parabola from standard form to vertex form.
The first step in completing the square is to group the quadratic and linear term:
[tex]h(t)=-5t^2 + 10t + 6\\\\h(t) = (-5t^2 + 10t) + 6[/tex]
Now factor out the coefficient of the quadratic term:
[tex]h(t)=-5(t^2 -2t) + 6[/tex]
After doing so, add a constant such that the terms inside the parenthesis form a perfect square, don't forget to balance the equation by adding the inverse of the added constant term:
[tex]h(t) = -5(t^2 -2t) + 6\\\\h(t) = -5(t^2 -2t + 1 -1 ) + 6[/tex]
Now take the balancing term out of the parenthesis:
[tex]\\\\h(t)=-5(t^2 -2t + 1) + 6 + ((-1)(-5))[/tex]
Simplify:
[tex]h(t) = -5(t^2 -2t + 1) + 6 + 5\\\\h(t) = -5(t-1)^2 + 11[/tex]
The x-coordinate of the vertex of the parabola is equal to the additive inverse of the numerical part of the quadratic term. The y-coordinate of the vertex is the constant term outside of the parenthesis. Thus, the vertex of the parabola is:
[tex](1, 11)[/tex]

Supplementary Angles: Angles that add up to 180°Step-by-step explanation:
Step 1: Define
We can see from the diagram that the 2 angles are supplementary
(6x - 10)° + (7x + 8)° = 180°
Step 2: Solve for x
Combine like terms: 13x - 2 = 180[Addition Property of Equality] Add 2 on both sides: 13x = 182[Division Property of Equality] Divide 13 on both sides: x = 14Write the equation(y=mx) for the line that contains the points (6,6) and (10,14). No picture

Which linear function is graphed on the grid?
a - g(x) = 2/15x - 6
b - g(x) = 2/15x + 45
c - g(x) = 15/2x - 6
d - g(x) = 15/2x + 45
Answer:
G(x)=2/15x-6
Step-by-step explanation:
The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
x/a + y/b = 1
Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.
From the graph, the x-intercept is - 6, and the y-intercept is 45. Then the equation is given as,
x/(-6) + y/45 = 1
- 15x + 2y = 90
y = (15/2) x + 45
g(x) = (15/2) x + 45
The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

The points (-7, -1) and (r, 1) lie on a line with slope 1/4
Find the missing coordinater.
r =
Answer:
r = 1
Step-by-step explanation:
Find the missing x-coordinate r.
Use the point-slope formula y - k = m(x - h). We are given the point (-7, -1) on the line and the slope of the line 1/4, and so this general formula becomes
y + 1 = (1/4)(x + 7)
Now substitute the coordinates of the other point (r, 1) to solve for r:
1 + 1 = (1/4)(r + 7)
Multiplying both sides by 4 eliminates the fractional coefficient:
8 = r + 7
It is readily apparent that r must be 1.
Check: If r = 1, then (r, 1) becomes (1, 1). use the point-slope formula again, this time to see if we are correctly predicting the r value 1:
y + 1 = (1/4)(x + 7) becomes 1 + 1 = (1/4)(r + 7), or
2 = (1/4)(r + 7). Multiplying both sides by 4, we get 8 = r + 7, and so r = 1.

what is ratio?
what is rote?
write each of ffg ratio in its simplest form . first make the units the same in each case
a)90 sec to 7min
b)48min to 3hours
c)2,5 days to 80hours
d)3 800mm to 3m
e)2,5 to 7am
f)5 300m to 2,5km
Answer:
a) 3 : 14
b) 4 : 15
c) 3: 4
d) 19 : 15
e) 53 : 25
Step-by-step explanation:
a)90 sec to 7min
We convert 7 mins to seconds
1 minute = 60 seconds
7 minutes = x seconds
Cross Multiply
x = 7 × 60 seconds = 420 seconds
Hence,
Our ratio is
90 seconds : 420 seconds
Divide both sit by 30
= 3 : 14
b)48min to 3hours
We convert 3 hours to minutes
1 hour = 60 minutes
3 hours = x minutes
Cross Multiply
x = 3 × 60 minutes = 180 minutes
Hence,
Our ratio is
48 minutes : 180 minutes
Divide both sides by 12
4 : 15
c)2.5 days to 80hours.
We are converting 2.5 days to hours
1 day = 24 hours
2.5 days = x
Cross Multiply
x = 2.5 × 24 hours = 60 hours
Hence,our ratio
60 hours : 80 hours
Divide both sides by 20
3: 4
d)3 800mm to 3m
We convert 3 m to mm
1 m = 1000 mm
3 m = x mm
Cross Multiply
x mm = 3 × 1000 mm
x mm = 3000mm
Hence, ratio is
3800 mm : 3000mm
Divide both sides by 200
19 : 15
e)5300m to 2.5km
We convert km to m
1 km = 1000 m
2.5 km = x m
Cross Multiply
x m = 2.5 × 1000m
x = 2500m
Hence, our ratio
5300m : 2500m
Divide both sides by 100
53 : 25
