Which ordered pair is a solution of the equation?
y=-2x-5
Choose 1 answer:
A. Only (1,7)
B. Only (2,-7)
C. Both (1,7) and (2,-7)
D. Neither
Answer:
D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Just plug the numbers in.
y=-2x-5
(Plug in 1,7)
7=-2(1)-5
7=-7
So not (1,7)
y=-2x-5
(Plug in 2,-7)
-7=-2(2)-5
-7=-9
So not (2,-7)
Which means none of these answers are correct.
The only correct solutions to this equation are (0,-5) and (1,-7)

The formula V=R-N describes the variation V of the recorded temperature R from the normal temperature N. If the recorded temperature is -4.6 degrees F and the normal temperature is 3.2 degrees F, what is the variation from the normal temperature?
Answer:
-7.8
Step-by-step explanation:
We will substitute the recorded temperature (-4.6) in the “R” (in the formula) and we will substitute 3.2 in the normal temperature “N”. So you should have V= -4.6 - 3.2 (negative Four point six subtracted by three point two) then solve. This should give you -7.8. Remember your integers!

Which situation can be represented by this inequality?
135 ≤ 10r + 15
Question 8 options:
A Hugo has 10 songs in his music player. He will add 15 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at most 135 songs?
B Hugo has 10 songs in his music player. He will add 15 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at least 135 songs?
C Hugo has 15 songs in his music player. He will add 10 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at most 135 songs?
D Hugo has 15 songs in his music player. He will add 10 songs every month. Hugo collects songs for r months. For what values of r will Hugo have at least 135 songs?
Answer:
D
Step-by-step explanation:
So the key to figuring this equation is writing it out. If Hugo already has 15 songs, then he will add 15 at the end for his collection. If he gets 10 every month, for r months, you must multiply them for 10r. You do this because you get 10 for r, the amount of months. This is where you add the 15, since it is your collection total.
so far we have 10r + 15
For teh last part we see that the equation, 135 ≤ 10r + 15, says that 135 is less than or equal to our 10r +15. This means that D has to be the answer since nothing else will fit.
Gary purchased a dvd that was on sale for 15% off the sales tax in his county is 5% let X represent the original price of the dvd. Write a expression that can be used to find the final cost of the dvd
Detailed explanation please :) that way I’ll understand it if I come along a problem like this again
Answer: 0.8925 x
Step-by-step explanation:
First, he gets it on sale, so (x-0.15x = 0.85 x)Then, take that 0.85x and multiply it by 1.05 (to add the sales tax). So the result is (0.85 x)(1.05) = 0.8925 x

Solve Equations by Substitution
f
Determine whether the given value for the variable is the solution to the equation.
2n+5=27; n=11
Substitute the value for the variable.
2⋅11+5=?27
The value for n is 11, so replace n with 11.
Think About ItWhy does the equals sign have a question mark above it?
While the expression on the left has a variable, the expression has no value. Once we replace the variable with a number, the expression immediately has a value. Until we simplify that expression, we don’t know what this value is and whether or not it’s the same value as the expression on the right. Therefore, we place a question mark over the equals sign to show that we don’t know whether the expressions are equal.
Simplify.
2⋅11+5=?27
22+5=?27
27=27
The left side of the equation has an expression that must be simplified. Follow the order of operations. First, multiply 2 by 11 to get 22. Then, add 22 and 5 to get 27. Since the expression on the left is the same as the expression on the right, the expressions are equal.
Conclude.
n=11 is the solution to the equation.
Since substituting 11 for n resulted in the expression on the left equaling the expression on the right, 11 is the solution to the equation.

What are the x-intercepts of the function g(x) = 4(x + 1)(x – 2)?
Answer:
Option A. (4,0) and (-1,0)
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to

a is a coefficient
x_1 and x_2 are the zeros or x-intercepts of the function
In this problem we have
we have
The leading coefficient is negative, that means the parabola open downward
The zeros of the function are
Remember that the x-intercepts are the values of x when the value of the function is equal to zero
therefore

Callie evaluated the expression 0.42 times 4.73 using the steps shown below.
0.42 times 4.73 = 1.26. 1.26 + 29.40 + 168.00 = 198.66
Which best explains Callie’s error?
Callie incorrectly placed the decimal.
Callie multiplied incorrectly.
Callie added incorrectly.
Callie incorrectly used placeholder zeros.
Answer:
Callie multiplied incorrectly
Step-by-step explanation:
Here we have 0.42 × 4.73 = 1.9866 then
1.9866 + 29.4 + 168 = 199.3866
we had 0.42 × 4.73 = 1.26 which is incorrect meaning that Callie multiplied incorrectly
Callie multiplied as follows
0.42 × 3 = 1.26 but what was in the question was
0.42 × 4.73 which is equal to 1.9866.
Answer:Callie multiplied incorrectly

Answer:
x < 10
Hope this helps lovely!~
Answer: < 10
Step-by-step explanation:
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
it can be 5 , or any number greater than 5 . So, the phrase 'x is at least 5 ' means 'x≥5 x ≥ 5 '.

Parker runs a farm stand that sells strawberries and peaches. Each pound of strawberries sells for $1 and each pound of peaches sells for $1.50. Parker sold 3 times as many pounds of strawberries as pounds of peaches and he made $54 altogether. Graphically solve a system of equations in order to determine the number of pounds of strawberries sold, x,x, and the number of pounds of peaches sold, yy.
Answer:
12 peaches, 36 strawberries
Step-by-step explanation:
let's say he sold x peaches, so 3x strawberries
3x + 1.5x = 54
4.5x = 54
x = 12
12 x 3 = 36
A value Parker runs a farm stand that sells strawberries and peaches. Parker sold 36 pounds of strawberries and 12 pounds of peaches
Let's denote the number of pounds of strawberries sold as "x" and the number of pounds of peaches sold as "y".
Each pound of strawberries sells for $1.
Each pound of peaches sells for $1.50.
We also know that Parker sold 3 times as many pounds of strawberries as pounds of peaches:
Equation 1: x = 3y
And the total amount made was $54:
Equation 2: 1x + 1.5y = 54
these equations to find the point of intersection, which represents the solution:
Equation 1: x = 3y
Equation 2: 1x + 1.5y = 54
First, we'll rearrange Equation 1 to solve for y: y = x/3.
Now, let's substitute this value of y into Equation 2:
1x + 1.5(x/3) = 54
1x + 0.5x = 54
1.5x = 54
x = 36
The value of x find y using the equation y = x/3:
y = 36/3
y = 12
These equations to visually confirm the solution:
x-axis: Pounds of strawberries (from 0 to 40)
y-axis: Pounds of peaches (from 0 to 20)
Plot the line y = x/3 (this represents the relationship x = 3y), and plot the line 1x + 1.5y = 54. The point where these lines intersect is the solution (36, 12).
