Carlos has 2 dollars more than half of the total amount of money his brother has. If x represents the amount of money Carlos's brother has, which expression can be used to represent this situation?
Answer:
[tex]y = 2 + \frac{1}{2}x[/tex]
Step-by-step explanation:
Given
Represent Carlos with y and his brother with x.
Analysing the statement one after the other:
Half of his brother's amount is: [tex]\frac{1}{2}x[/tex]
$2 more: means we add 2 to [tex]\frac{1}{2}x[/tex]
So, we have: [tex]2 + \frac{1}{2}x[/tex]
The above represent Carlos's amount.
So, the expression is:
[tex]y = 2 + \frac{1}{2}x[/tex]
Find the measure of angle b
what does x equal in this equation -5x + 8 = -2
Answer:
x = 2
Step-by-step explanation:
-5x + 8 = -2
-5x + 8 - 8 = -2 -8
-5x = -10
-5x/5 = -10/5
-x = -2
x=2
Simplify the equation:
-5x = 2 + 8
-5x = 10
x = -2
Write the slope intercept form of the equation of each line
Answer:
The slope is 1/4 so the slope intercept form is y=1/4+3
Step-by-step explanation:
To find the slope the easiest way from looking at a graph is just to find the rise over run. From looking at the graph we can see that the next point from 0,3 is 4,4. The y here is increased by 1, which means the rise is 1. The x is increased by 4 so the run is 4. From putting rise (1) over run (4) the slope is 1/4. The formula for slope intercept is y=mx+b. m is slope so we substitue that for 1/4 so now we have y=1/4x+b. Then the b is the y intercept, or, at what point the line crosses the y line. Which in this case is 0,3 so the y intercept would be 3 because that is what height it crosses the y line.

What is the slope of this line?
(sorry for the quality.)
Answer:
slope = - 1
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 ) = (- 8,6) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line
m = [tex]\frac{-2-6}{0+8}[/tex] = [tex]\frac{-8}{8}[/tex] = - 1

Si un hombre de 1.75m de altura proyecta una sombra de 3.50m que sombra aproximada proyecta un poste de 8.25m
Answer:
4.25 m
Step-by-step explanation:
Resolvemos esta pregunta usando la fórmula:
Altura del hombre / Sombra de un hombre = Altura del palo / Sombra del palo
Sombra del hombre = 3.50 m
Altura de un hombre = 1.75 m
Sombra del palo = 8.50 m
Altura del palo = x
Por lo tanto:
1.75 / 3.5 = x / 8.5
Cruz multiplicar
1.75 × 8.5 = 3.5 × x
14.875 = 3.5x
x = 14.875 / 3.5
x = 4.25 metros
Por tanto, la altura del palo = 4.25 m

A line passes through the point (8, -2) and has a slope of 5/4. Write an Equation in point-slope form for this line
Answer:
y=5/4x-8
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
General Point Slope Form is:
[tex]y-y_1=m(x-x_1)\\\\\rightarrow \text{m - slope}\\\\\rightarrow (x_1,y_1)\text{ - given point}[/tex]
We are given the slope of (5/4) and the point of (8, -2).
Replace the variables with their appropriate values:
[tex]x_1 \rightarrow8\\\\y_1\rightarrow-2\\\\m\rightarrow\frac{5}{4}\\\\\text{Replace } x_1, y_1, \text{and } m \text{ with the appropriate values.}\\\\y-y_1=m(x-x_1)\rightarrow y-(-2)=\frac{5}{4}(x-8)\\\\\text{Simplify:}\\\\y-(-2)=\frac{5}{4}(x-8)\rightarrow y+2=\frac{5}{4}(x-8)\\\\\\\text{Our final answer is:}\\\\ \huge\boxed{y+2=\frac{5}{4}(x-8)}[/tex]

A principal of $2900 is invested at 6.25% interest, compounded annually. How much will the investment be worth after 14 years?
Answer:
$6774.4
Step-by-step explanation:
Given data
P=$2900
r= 6.25%
t= 14 years
A=???
The compound interest formula is given as
A=P(1+r)^t
substiute
A= 2900(1+0.0625)^14
A= 2900(1.0625)^14
A= 2900*2.336
A= $6774.4
Hence the final amount is $6774.4

(6y + 10) - (2y + 3)
Answer:
4y+7
Step-by-step explanation:
First, remove the unnecessary parenthesis. Add like terms (In this case it’s y) So it will be 6y-2y. Which gives you 4y. And then after that 10-3, which gives you 7. So your final answer is 4y+7!!

the cost of the remaining amount. How much does sheet metal cost per square foot?
Sheet metal costs $ per square foot.
ANSWER=30
because if you 8.2-2.3 you get 5.9 and if you divide by 177 it is 30
