Step-by-step explanation:
The y-intercept is the y-value for when the line intersects with the y-axis. Another way to put this is also the y-value when x=0. This is easy to find when you have a graph because you can simply look to see where on the graph the line intersects with the axis. If you don't have the graph then you can plug 0 in for x in the equation and solve.

if h(t) = -3t + 6 + 7t, What is h(3)
Answer:
h(3) = 18
Step-by-step explanation:
Step 1: Define
h(t) = -3t + 6 + 7t
h(3) is x = 3
Step 2: Simplify
h(t) = 4t + 6
Step 3: Substitute and Evaluate
h(3) = 4(3) + 6
h(3) = 12 + 6
h(3) = 18

slope of 1?
Answer:
y = x + 3
Step-by-step explanation:
y = mx + b
-4 = -7 * 1 + b
-4 = -7 + b

On a coordinate plane, 2 trapezoids are shown. Trapezoid 1 has points A (negative 4, 3), B (1, 3), C (0, 0), and D (negative 3, 0). Trapezoid 2 has points A prime (negative 1, 1), B prime (4, 1), C prime (3, negative 2), and D prime (0, negative 2).
Which rule describes the translation?
it is c
Answer:
Horizontal shift by 3 units right and vertical shift by 2 units down or(x, y) → (x + 3, y -2)Step-by-step explanation:
GivenTrapezoid 1 with vertices
A(-4, 3), B(1, 3), C(0, 0), D(-3, 0)and
Trapezoid 2 with vertices
A'(-1, 1), B'(4, 1), C'(3, -2), D'(0, -2)It can be observed by comparison that:
x-values have increased by 3 unitsand
y-values have decreased by 2 unitsSo the rule of translation is:
Horizontal shift by 3 units right and vertical shift by 2 units down(x, y) → (x + 3, y -2)Answer:
3 units right, 2 units down(x, y) = (x + 3, y - 2)Step-by-step explanation:
another way is by graphing. (see attached)
the translation is:
3 units right, 2 units down.
or (x, y) = (x + 3, y - 2)

What are the two values on a number line that are a
distance of 5 from 0?
Answer:
the two values that are a distance of 5 from 0 are -5 and 5.
Step-by-step explanation:
if you look at a number line, you will see that the number 0 is in the middle. if you count 5 from each side, it's -5 and 5. any other number would have a greater distance than 5 from 0. hope this helps.

f(x)=5(2-x) if f(-6)?
Answer:
f(-6) = 40
Step-by-step explanation:
Step 1: Define
f(x) = 5(2 - x)
f(-6) is x = -6
Step 2: Substitute and Evaluate
f(-6) = 5(2 - (-6))
f(-6) = 5(2 + 6)
f(-6) = 5(8)
f(-6) = 40

How many 1/8 teaspoons are equal to 4 3/4 teaspoons?
1. Convert fraction into same decimal.
To find this answer, we want to first convert the fraction so that the denominators are the same:
3/4 = ?/8
Divide the original denominator by the needed-to-be denominator.
8 / 4 = 2
Do reversal calculations
4 x 2 = 8
So, now that we know to multiply the original denominator by 2 to get the new denominator, multiple the numeriator by the same.
3 6
_ x 2 = _
4 8
So now, the new equation is:
How many 1/8 teaspoons are equal to 4 6/8 teaspoons.
(The reason why you must convert is because then you can simply say that the fraction is 6 1/8's, which means you just have to worry about the whole numbers.
2. Convert the whole numbers into a fraction to make it easier.
In order to convert whole numbers into fractions, first find the denominator your using. Which in this case, it is 8.
?/8
Now remember, for it to be a whole number, the numeriator and denominator MUST be the same.
8/8 = 1
Now remember, there are four 1's. Multiply the numeriator by 4, but keep the denominator the same or else the equation is ruined.
32/8 = 4
3. Add all your information together.
DO NOT forget to add the information you collected during the equation, or else you will get a wrong answer. Add the equation's final answer to the whole numbers final answer.
32 / 8 + 6 / 8 = ?
32 / 8 + 6 / 8 = 38 / 8
Well now, remember something. It is asking us, how many 1/8's were in the equation 4 3/4. We have transformed 4 3/4 into a whole equation, 38/8.
Now, all you need to do is look at the numeriator.
What number do you see?
You see 38.
The denominator is the correct denominator that you need. So, the number of the numeriator is the answer to the equation.
So, how many 1/8 are in 38/8?
38!
The number of ⅛ teaspoons will equal 4¾ teaspoons is; 38 teaspoons
We want to find how many ⅛ teaspoons will equal 4¾ teaspoons.
To start with, let us convert 4¾ teaspoons from mixed fraction to improper fraction to get;
4¾ teaspoons = 19/4 teaspoons
Now to find out how many ⅛ teaspoons will equal 19/4 teaspoons, all we need to do is to divide 19/4 by ⅛
Thus;
19/4 ÷ 1/8
>> 19/4 × 8/1
>> 38 teaspoons
In conclusion the number of ⅛ teaspoons that are equal to 4¾ teaspoons is 38 teaspoons.

A researcher is exploring the notion that there is an economy of scale in raising children. While having one child might add to a family's financial stress, the second or third one might not be as "expensive" since they would already be sharing one roof, could share clothing, etc. The researcher has access to a large community of parents where 15% have one child under 18 in their home, 65% of parents have two children, and 20% of parents have three or more children. Rounded to the nearest whole number, the probability that any given family who is selected has two or more children at home is ________ %?
Answer:
The probability is [tex]G = 85% [/tex]
Step-by-step explanation:
From the question we are told that
The percentage of parents that have one child under 18 in their homes is k = 15%
The percentage of parents that have two children is T = 65%
The percentage of parents that have three or more children is Y = 20%
Generally the probability that any given family who is selected have two or more children at home is mathematically evaluated as
[tex]G = T + Y[/tex]
=> [tex]G = 65% + 20% [/tex]
=> [tex]G = 85% [/tex]
what are the measures of angles a,b,c ?
Answer:
a=30 , b=60, c=105
Step-by-step explanation:
a=30 [Being vertically opposite angle]
Now,
a+b+90=180 [Being the sum of interior angles of a triangle]
or, 30+b+90=180
or, b+120=180
or, b=180-120
so, b= 60
Again,
c+75= 180 [Being linear pair]
or, c=180-75
so, c= 105
What is the slope, y-intercept, and x-intercept of (7,-6) and (10,9)
Answer:
Slope: 5
X Intercept: (8.2,0)
Y Intercept: (0, -41)
Step-by-step explanation:
Slope:
y2-y1/x2-x1=9-(-6)/10-7=9+6/10-7=15/3=5
y=5x-41 - the slope intercept form
X Intercept:
if y=0

41=5x
8.2=x
(8.2,0)
Y Intercept:

What is the 50th term for -7,-2,3 ...?
a(50) = 238
Step-by-step explanation:The constant (diference) = 5
-2 - (-7) = - 2 + 7 = 5
3 - (-2) = 3 + 2 = 5
use formula
a(n) = a + (n - 1)d
a = - 7
n = 50
d = 5
a(50) = - 7 + (50 - 1)5
= - 7 + 49ₓ5
= - 7 + 245
= 238
