Answer:
13m
Step-by-step explanation:
this is because she needs 130
Answer:
13 months
Step-by-step explanation:
subtract 120 from 250 because that is how much she already has and then divide that answer by ten which will give you the number of months
What is the equation of the line that passes through the point (8,-4) and has a slope of 1/2
The equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
This is the required equation of a line in a point-slope form.
We know that Point-Slope Form:
y - y₁ = m(x- x₁)
Where x₁ - x coordinate and y₁ - y coordinate
m - slope
Point (8,-4)
Then Slope m = 1/2
Now the equation as;
y + 4 = 1/2(x - 8)
y = -1/2(x -4) - 4
y = -x/2 + 2 - 4
y = -x/2 - 2
Hence, the equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2

#SPJ2
Is the ratio 4.2:1.5 proportional to the ratio12.6:4.5? Explain.
Answer:
No
Step-by-step explanation:
All the numbers have to be multiplied by the same amount for it to be proportional
A proportional amount to 4:2:1:5 would be 12:6:3:15
They have all been multiplied by the same number 3
Answer:
Yes, the ratio is proportional
Step-by-step explanation:
given 4.2 : 1.5 =? 12.6 : 4.5 is it proportional
it must follow the means extremes property
[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex]
a*d = b*c, so let's plug in the values
[tex]\frac{4.2}{1.5}[/tex] =? [tex]\frac{12.4}{4.5}[/tex]
(4.2)*(4.5) =? (1.5)*(12.6)
18.9 = 18.9 which is true; therefore the ratio is proportional
Is this graph a function or not a function
Answer:
In the graph of a circle, we can easily draw a straight vertical line passing through its center. This will hit the top and the bottom of the shape. Since this line hits two points, a circle's graph is not a function. We can also observe the equation of a circle.
Answer:
No
Step-by-step explanation:
Do a vertical line test.
First, put your pencil or ruler up against the screen.
Move it down the graph and if there are two points in one x point, it is not a function. For example, look at 0, 3 and 0, -2.5. They share the same x point.
Therefore, it is not a function.
Find each numbered angle measure:
Answer:
m∠1=77°
m∠2=36°
m∠3=30°
Step-by-step explanation:
First, find angle 1 by adding 66 and 37 and subtracting them from 180 because there are 180 degrees in an angle.
180-(66+37)=77°
You can then find angle 2 by finding the other angle not given. You can find this angle by subtracting 77 from 180, giving you 103. To find angle 2, add 103 and 41 and subtract them from 180.
180-(103+41)=36°
You can then find angle 3 by adding the angle 103 and the angle 47, and subtracting them from 180
180-(103+47)=30°

If 1 yard = 3 feet and 1 mile = 5,280 feet, how many yards are there in 5 miles? (3 points)
A. 79,200 yards
B. 26,400 yards
C. 8,800 yards
D. 352 yards
Answer:
there are 8800 yards in 5 miles
Step-by-step explanation:
there are 1760 yards in a mile and multiply that by 5 to get 8800
its C because if you multiply 5280 by 5 is 26400 feet in 5 miles but we need yards so then we divide 26,400 by 3 witch is
Awnser: 8,800 yards or C

Answer:
A. {1, 7, 11}
Step-by-step explanation:
The constant in the equation is 1, so that is the value when x=0. No answer choice can be correct unless it includes the value 1. The only viable choice is A.
_____
If you want to go to the trouble to evaluate the expression for the different values of x, you can. It often works well to rewrite the expression to "Horner form":
(2x -1)x +1
For x = -2, this is (2(-2) -1)(-2) +1 = (-5)(-2) +1 = 11
For x = 0, this is 1
For x = 2, this is (2(2) -1)(2) +1 = (3)(2) +1 = 7
So, the range for the given domain is {1, 7, 11} . . . . . matches choice A
