Answer:
-15 Is the answer
Step-by-step explanation:
(-5)(7)+4×5
= -15
(-5)(7) + 4×5 = -15/1 = -15
Multiple: -5 * 7 = -35
Multiple: 4 * 5 = 20
Add: the result of step No. 1 + the result of step No. 2 = -35 + 20 = -15

Let L = length and W = Width
The problem says L = 2W
and
Area = LW = 21
Substitute
2W2 = 21
W2 = 10.5
W = 3.24

Given x + y = x ∙ y = 3, determine x3 + y3 ?
Answer:
Step-by-step explanation:
x³ + y³ = (x + y)(x² - xy + y²)
= (x + y)(x² + 2xy + y² - 3xy)
= (x + y)[(x + y)² - 3xy]
= 3(3² - 3(3)) = 3(0) = 0
Polygon LMNPQR is shown on the coordinate grid and models the shape of a garden in a park,
Polygon LMNPQR will be dilated with the origin as the center of dilation to create polygon
L'M'N'P/Q'R'. The vertex Q' will be located at (21, 7).
Which rule best represents the dilation?
Dilation involves changing the size of the polygon
The best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]
How to determine the ruleThe coordinates of vertices Q and Q' are given as;
Q = (6,2)
Q' = (21, 7)
The scale factor of dilation is then calculated as:
[tex]k = \frac {Q'}{Q}[/tex]
So, we have:
[tex]k = \frac {(21,7)}{(6,2)}[/tex]
Factorize
[tex]k = \frac {7/2(6,2)}{(6,2)}[/tex]
Divide
[tex]k = \frac {7}2[/tex]
So, the transformation rule is:
[tex](x,y) \to \frac 72(x,y)[/tex]
Hence, the best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]

Leo practices piano for a
minimum of 90 minutes each
week. On Monday, he
practiced 10 minutes. For the
rest of the week, he practiced
in 20-minute sessions. How
many sessions would it take to
meet his goal?
Answer:
4 sessions.
Step-by-step explanation:
He starts with 10 minutes practiced and has to finish his quota in 20 minute sessions, so we can represent that with the equation 90=20x+10. Then solve for x.
90=20x+10
Subtract 10
80=20x
Divide by 20
x=4
It would take 4 sessions.
Answer:
1 10 min session + x 20 min sessions = 90 min
10+20x=90
20x=80
x=4 sessions

f(n+1)=5f(n), where f(1)=3 and n>1
Answer:
[tex]f(n) = \frac35 5^n[/tex]
Step-by-step explanation:
Let's assume the solution is of the form [tex]f(n) = \alpha k^n[/tex], where [tex]\alpha[/tex] is to be determined on the starting condition, and [tex]k \in \mathbb{R} \ne 0[/tex]
[tex]f(n+1) -5f(n) = 0\\\alpha k^{n+1} -5 \alpha k^n=0\\\alpha k^n (k-5) = 0 \rightarrow k= 5[/tex]
at this point we can use our starting condition to determine the value of [tex]\alpha[/tex]:
[tex]f(1)=3 \rightarrow \alpha 5^1 =3 \rightarrow \alpha =\frac 35[/tex]
Our solution is, thus [tex]f(n) = \frac35 5^n[/tex]

If 50% of some number is 75, what is 200% of that same number?
Answer:
300
Step-by-step explanation:
A percentage is a unit of proportion that represents a ratio.
For this question let the unknown number be represented by the variable x. We know that 75 is 50% of x, or half of x. This means that we can find the unknown number by doubling 75.
75*2=150This means that x is 150. Next, we need to find 200% of 150. 200% of any number is that number times 2. So, to find the final answer we must once again double 150.
150*2=300So, the final answer is 300.
Answer:
Step-by-step explanation:
270
50% equals to 1/2 so 1/2x=75. Times 2 on both sides you get x=135.
So 135 is x and you multiply 135 by 200%. Which get you 270.
