An angle measures 10° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
50º & 40º
Step-by-step explanation:
complementary anlges add up to 90º. so, we can make an equation:
x+x-10=90
2x=100
x=50
so the angles are 50º and 40º.

Answer: I think so
Step-by-step explanation:
A cell phone normally sells for $500, but it is marked down 30% and you have a coupon for an additional 15% off. How much would it cost you to purchase the cell phone?
Answer:
$275
Step-by-step explanation:
30% + 15%=45%
45% of 500 is 225, because 500 x 0.45=225. Then subtract the discount from the total, 500 - 225, and you get 275
Can someone answer these two questions I submitted a photo of them it’s worth 50 points
Answer:
Step-by-step explanation:
1). Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Slope of a line passing through two points,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We take two points from the table given (-3, -19) and (0, -1)
m = [tex]\frac{-19+1}{-3-0}[/tex]
m = 6
y - intercept 'b' = -1 [For x = 0]
Therefore, equation of the line will be,
y = 6x - 1
2). Equation of a line passing through a point (x', y') is,
y - y' = m(x - x')
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We take two points from the given table as (2, 12) and (3, 18).
Slope of the line passing through these points will be
m = [tex]\frac{18-12}{3-2}[/tex] = 6
Equation of the line passing through (2, 12) will be,
y - 12 = 6(x - 2)
y = 6x - 12 + 12
y = 6x
By using a graphing tool we can graph these lines representing the tables.

Answer:
C
Step-by-step explanation:
You have to distribute the negative into the second set of parentheses first, and since 2x is positive, it will be negative, -3 is negative so it will be positive, and 18 is positive so it will be negative

On that day the bakery gave away a total of 29 free gingerbread man cookies what was the total number of free candy canes the bakery gave away on that day show how or explore how you got your answer
Answer: 19 people
Step-by-step explanation:
If every 4th customer received a free gingerbread man cookie and 29 cookies were given away then the number of customers that came were:
= 4 * 29
= 116 customers
Because 116 customers came, they were able to give 29 cookies by giving one to every 4th customer.
If there were 116 customers, the number of customers who got the free candy canes would be:
= 116/6
= 19.3
= 19 people
x^6+3x^3-5
write the expression in quadratic form
Step-by-step explanation:
[tex]v = {x}^{3} \\ {v}^{2} + 3v - 5 = 0 \\ [/tex]
Solving this equation using the quadratic formula, we get two real solutions :
1.1926 or -4.1926
Now we know the values of v , we can calculate x since x is ∛ v
[tex] {x}^{6} + 3 {x}^{3} - 5 = 0[/tex]
[tex]x = \sqrt[3]{1.1926} = 1.0605 \\ x = \sqrt[3]{ - 4.1926} = - 1.6125[/tex]

2x+y=17 in slope intercept form
Answer:
y=-2x+17
Step-by-step explanation:
So the problem is 2x+y=17, we know that slope intercept form is y=mx+b where m is the slope and b is the y-int.
All you have to do is isolate the y.
2x+y=17
-2x on both sides so you can leave the y alone.
y=-2x+17 should be the answer. Hope this helps!
If f(x) = 5 + 4(x - 4)?,
what is f(7)?
Answer:
Let's solve for f.
x=5+4(x−4)f(7)
Step 1: Flip the equation.
28fx−112f+5=x
Step 2: Add -5 to both sides.
28fx−112f+5+−5=x+−5
28fx−112f=x−5
Step 3: Factor out variable f.
f(28x−112)=x−5
Step 4: Divide both sides by 28x-112.
f(28x−112)28x−112=x−528x−112
f=x−528x−112
Answer:
f=x−528x−112
