the sun of two numbers is 59 and the difference is 15. what are the numbers?
Answer:
1st number: 37
2nd number: 22
Step-by-step explanation:
let n = 1st number
let n-15 = 2nd number
n+(n-15)=59
collect like terms: 2n-15=59
add 15 to both sides
2n=74
divide both sides by 2
n=37
n-15=22

Answer:
h(-2) = 32
[tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex]
Step-by-step explanation:
Given the linear function, h(x) = -7x + 18:
h(-2)In order to evaluate h(-2), simply substitute the value of the given input, x = -2, into the function.
h(x) = -7x + 18
h(-2) = -7(-2) + 18
h(-2) = 14 + 18
h(-2) = 32
Therefore, the output value when x = -2 is: h(-2) = 32.
Find x if h(x) = -2.
This particular problem asks us to find the corresponding domain (x-value) given the range value of y = -2.
Substitute the value of y = -2 into the function to solve for the value of x:
h(x) = -7x + 18
-2 = -7x + 18
Subtract 18 from both sides:
-2 - 18 = -7x + 18 - 18
-20 = -7x
Divide both sides by -7 to solve for x:
[tex]\displaystyle\mathsf{\frac{-20}{-7}\:=\:\frac{-7x}{-7} }[/tex]
[tex]\displaystyle\mathsf{x\:=\frac{20}{7}}[/tex]
Therefore, the value of x when h(x) = -2 is: [tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex].
A line passes through the point (10,-8) and has a slope of -5/2. write an equation in point-slope form for this line.
Answer:
y= -5/2 + 17
Step-by-step explanation:
y=mx+b
-8=-5/2(10)+b
-8=-25+b
17=b
y = -5/2x + 17

What percent of 25 is 10?
10 = x. 25; 40%
10 = x. 25; 250%
25 = x10; 4%
25 = x= 10; 250%
E
Answer:
40
Step-by-step explanation: Make a proportional relationship. Make 25% into a fraction, 25/100. Then make 10 into a fraction using a variable. For example 10/p. Then cross multiply. 100x10=1000. Divide 1000 by 25 and the answer would be 40.
How do i find the slope
Answer:
y=1/2x
Step-by-step explanation:
Its a positive slope so you go up 2 then right 4
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 3) ← 2 points on the line
m = [tex]\frac{3-0}{6-0}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
how many anwsers do you have to miss to master in a math test
Answer:
It depends
Step-by-step explanation:
It depends on how many problems are in the test. If the test has a standard amount of ten questions, you can only miss one question if you want to get a solid 90%. If the test has twenty questions, you can miss two to get that 90%.
If you're going for an 80% (or B), you can miss two on a ten-question test and four on a twenty-question test.
Again, it all depends on the number of questions and what percentage you want to get on the test.
When the domain is restricted, you can pick any value to substitute in for the
independent variable.
True
O False
Answer:Therefore, the domain is restricted to non-negative values of x so that the function values will be defined. The variable x is often referred to as the independent variable, while the variable y is referred to as the dependent variable
Step-by-step explanation:
For 4 weeks, William volunteered as a helper for swimming classes. The first week, he volunteered for 8 hours. He volunteered for 12 hours in the second week, and another 12 hours in the third week. The fourth week, he volunteered for 9 hours. For how many hours did he volunteer per week, on average? (write a sentence answer)
Answer:
He volunteered 10 hrs 15 min on average.
Step-by-step explanation:
The first week: 8 hrs
The second week: 12 hrs
The third week: 12 hrs
The fourth week: 9 hrs
8 + 12 + 12 + 9 = 41 hrs total
41 hours/4 weeks = 10.25 hrs (10 hrs 15 min)
Answer: 10.25 hours/week (On average, William volunteered 10.25 hours per week during these four weeks)
Step-by-step explanation:
To find an average, you need to add up each entity:
8+12+12+9=41
After that, you divide that number by n (the number of weeks)
41/4=10.25 hours

Help pleasee last question
Answer:
1/5
Step-by-step explanation:
it appears as those two distinct points on the graph are (-3,1) and (2,2)
so take the difference of the y-values and put it over the difference of the x-values to get a fraction to represent the slope
2-1 / 2-(-3) = 1/5
if you start from the point (-3,1) you must rise by one unit and then run five units to the right to get to (2,2)
Question 1 What is the slope of the line that is represented by the equation y−15=−6(x+7)?
Step-by-step explanation:
Change the equation to the general form [tex]Ax + By + C = 0[/tex].
[tex]y - 15 = - 6(x + 7) \\ y - 15 = - 6x - 42 \\ 6x + y - 15 + 42 = 0 \\ 6x + y + 27 = 0[/tex]
The slope
[tex] = - \frac{A}{B} [/tex]
[tex] = - \frac{6}{1} [/tex]
[tex] = - 6[/tex]
Answer: Slope is -6
Step-by-step explanation:
We want to rearrange the equation to the form of y=mx+b, where m is the slope and b the y-intercept.
y−15=−6(x+7)
y−15=−6x-42
y=−6x-42+15
y = -6x - 27
The slope is -6

Solve the absolute value equations algebraically
|m+4|+7=11
Answer:
m=0,-8
Step-by-step explanation:
Rearrange this Absolute Value Equation
|m+4|+7 = 11
Another term is moved / added to the right hand side.
|m+4| = 4 STEP 2:
Clear the Absolute Value Bars
The Absolute Value term is |m+4|
For the Negative case we'll use -(m+4)
For the Positive case we'll use (m+4)
STEP3:Solve the Negative Case
-(m+4) = 4
Multiply
-m-4 = 4
Rearrange and Add up
-m = 8 Multiply both sides by (-1)
m = -8
Which is the solution for the Negative Case
STEP4:Solve the Positive Case
(m+4) = 4
Rearrange and Add up
m = 0
Which is the solution for the Positive Case
STEP5:
Wrap up the solution
m=-8
m=0
Solutions on the Number Line
Two solutions were found :

X-4/2 = 4x-9/3
A x=-6
B x=-3/5
C x=6/5
D x =6/11
Answer:
x = 6/5
Step-by-step explanation:
x-4 4x-9
------ = ----------
2 3
Using cross products
3 * (x-4) = 2 ( 4x-9)
Distribute
3x-12 = 8x-18
Subtract 3x from each side
3x-12-3x = 8x-18-3x
-12 = 5x-18
Add 18 to each side
-12+18 =5x-18+18
6 = 5x
Divide by 5
6/5 = 5x/5
6/5 =x

A solid metal sphere with diameter 10cm needs to be covered with a protective material which costs £0.29 per cm2. How much will it cost to cover the sphere with the material? Give your answer rounded to 2 DP.
Answer:
1083.45
Step-by-step explanation:
Diameter = 2r
Radius = 5cm because the diameter is 10.
4 pie r^2 is the surface area. = 314.2.
314.2/0.29 = 1083.45 Pounds
Use the distributive property to remove the parentheses. -6(5y-2u-3)
by multiplying each term in the parentheses by the term outside
-6(5y-2u-3) = (-6 × 5y) + (-6 × - 2u) + (-6 × -3)
= -30y + 12u + 18
What is 3/8 x 2/5 equals to what
Answer:
[tex]=\frac{3x}{20}[/tex]
Step-by-step explanation:
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \:a\cdot \frac{b}{c}\cdot \frac{d}{e}=\frac{a\:\cdot \:b\:\cdot \:d}{c\:\cdot \:e}[/tex]
[tex]=\frac{3x\cdot \:2}{8\cdot \:5}[/tex]
[tex]=\frac{3x}{4\cdot \:5}[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:4\cdot \:5=20[/tex]
[tex]=\frac{3x}{20}[/tex]
Answer:
Do you mean 3/8 times 2/5? It equals 3/20
Step-by-step explanation:
So multiple the top numbers together for the top result and multiple bottom numbers for bottom result. 3 times 2 equal 6, 8 times 5 equal 40. the result is 6 over 40. After simplifying, we have 3 over 20 (dividing both 6 and 40 by 2)

What is the solution set for this inequality? −6x + 30 < −18
Question 4 options:
x < -2
x > 8
x < 8
x > -2
Answer:
B. X > 8
Step-by-step explanation:
when dividing a negative denominator, you are flipping the sign. if the denominator doesn't have a negative sign, the sign isn't flipped.
steps:
subtract 30 by -18.
Soon you receive -48. Divide that by -6.
The signs soon flip giving you X> 8
