Can someone help me solve this triangle please?
what are the x-intercepts of the parabola? y=-3(x+5)(x-9)
Answer:
-5 and 9
Step-by-step explanation:
Graph the equation on a graph.
You can also simplify the equation into y=mx+b form and then graph:
y=-3(x+5)(x-9)
y=(-3x-15)(x-9)
y=-3x^2+27x-15x+135
y=-3x^2+12x+135

A man discovered he had only $5 bills and $1 bills. The number of $1 bills was 4 more than 3 times the number of $5 bills. He had a total of $36. How many of each kind of bill did he have?
The man had 4 $5 bills and 16 $1 bills.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let x be the number of $5 bills and y be the number of $1 bills.
From the problem, we know that:
y = 3x + 4 (since the number of $1 bills was 4 more than 3 times the number of $5 bills)
The total amount of money the man had is $36, so we can write:
5x + 1y = 36
Substituting the first equation into the second equation, we get:
5x + 1(3x + 4) = 36
Simplifying and solving for x, we get:
5x + 3x + 4 = 36
8x = 32
x = 4
So the man had 4 $5 bills.
Using the first equation, we can find the number of $1 bills:
y = 3x + 4 = 3(4) + 4 = 16
Therefore,
The man had 4 $5 bills and 16 $1 bills.

Donna is putting money into a savings account. She starts with $450 in the savings account, and each week she adds $70.
Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Donna has been adding money. Write
an equation relating to W. Then use this equation to find the total amount of money in the savings account after 14 weeks.
Answer:
1430
Step-by-step explanation:
S=450+70T
S= 450 + 70(14)
S=450+980
S=1430
Which expression is equivalent to 2 (a + 2 b) minus a minus 2 b? 3 a + 2 b 3 a minus 2 b a minus 2 b a + 2 b
Answer:
a + 2b
Step-by-step explanation:
Given the expression
2(a+2b) - a-2b
Open the bracket
2a+(2)2b- a-2b
2a+4b - a-2b
Collect the like terms
2a-a+4b-2b
a + 2b
Hence the equivalent expression is a + 2b

Monica has this recipe for fruit salad. 2 1/2 cups of pers, 2/3 cups of grapes, 1 1/4 cups of apples, and 1/2 of orange slices. How many cups for fruit is it in total?
Answer:
[tex]3\frac{11}{12}[/tex] cups
Step-by-step explanation:
[tex]2\frac{1}{2} = \frac{5}{2}[/tex] of pears
[tex]\frac{2}{3}[/tex] of grapes
[tex]\frac{1}{4}[/tex] of apples
[tex]\frac{1}{2}[/tex] of orange
when adding fractions, make sure all denominators are the same:
[tex]\frac{5}{2} = \frac{30}{12}[/tex] of pears
[tex]\frac{2}{3} = \frac{8}{12}[/tex] of grapes
[tex]\frac{1}{4} = \frac{3}{12}[/tex] of apples
[tex]\frac{1}{2} = \frac{6}{12}[/tex] of orange
add all of the fractions:
[tex]\frac{30}{12} + \frac{8}{12} + \frac{3}{12} + \frac{6}{12} = \frac{47}{12}[/tex]
convert to mixed fraction:
[tex]\frac{47}{12} = 3\frac{11}{12}[/tex]

After 32 years from now a boy will be 5 times as old as he was 8 years back.How old is the boy now?
Answer:
18 years
Step-by-step explanation:
Transforming the question in form of equation:
Let x be the current age.
x + 32 = 5(x-8)
x + 32 = 5x - 40
5x - x = 40 + 32
4x = 72
x = 18
Answer: look at this! He’s 18
Step-by-step explanation:
equation = x+32=5(x-8)
X+32=5x-40
5x-x=32+40
4x=72
X=72/4
=18

6. Which trig function would you use to solve for h? *
sine
cosine
tangent
Answer:
tan
Step-by-step explanation:
you can use this equation
[tex]tan(18) = \frac{h}{100} [/tex]
to solve for h
Answer:
Tangent
Step-by-step explanation:
Tangent=opposite/adjacent
For the angle that's 18°, it's opposite side is h, and the side that is next to, or adjacent to it is 100. It's not the other side because that's hypotenuse.
When you plug those in, you'll have:
[tex]tan(18)=\frac{h}{100}[/tex]
Solve for h by multiplying both sides by 100 to get:
[tex]100*tan(18)=h[/tex]
Put [tex]tan(18)[/tex] into calculator to get .324919. When you do so, make sure you're in degrees, not radians.
Since we are multiplying that by 100, the final answer is 32.4919

The length of Rectangle A is 20 inches and the width is 4 inches. The length of Rectangle B is
40 inches. Find the width of Rectangle B if the rectangles are similar.
Answer:
8 inches
Step-by-step explanation:
Let w be the width of rectangle B.
Since, both rectangles are similar.
Therefore, corresponding lengths and widths of rectangles A and B will be in proportion.
[tex] \therefore \frac{20}{40} = \frac{4}{w} \\ \\ \frac{1}{2} = \frac{4}{w} \\ \\ w = 2 \times 4 \\ \\ w = 8 \: inches[/tex]
Answer:
8"
Step-by-step explanation:
Lᵃ/Wᵃ = Lᵇ/Wᵇ
20"/4" = 40"/Wᵇ
Wᵇ = (4"×40")/20"
Wᵇ = 160" ÷ 20"
Wᵇ = 8"
Width of rectangle B = 8 inches
