what is the slop in the equation y=2x+3
Answer:
m = 2
Step-by-step explanation:
the slope intercept form is
y = mx +b, where m is the slope and b is the y-intercept
using the slope intercept form the slope will be two
3 = y intercept
2x = the slope
If f (x)
-3x + 2 and g (2) = x + 1 find g(f(x)) please helppp
[tex]\left \{ {{f(x)=-3x+2} \atop {g(x)=x+1}} \right.[/tex]
To find g(f(x)), Substitute f(x) in g(x).
[tex]g(-3x+2)[/tex]
Then substitute x = -3x+2 in g(x) = x+1
[tex]g(-3x+2)=(-3x+2)+1\\g(-3x+2)=-3x+2+1\\g(-3x+2)=-3x+3[/tex]
Therefore, the answer is [tex]g(f(x))=-3x+3[/tex]
A store sells wrapping paper for $3, greeting cards for $2, and ribbon for $1. The soccer
team buys 15 rolls of wrapping paper, 10 greeting cards, and 12 rolls of ribbon.
a. Write an expression to find the total cost of the soccer team's purchase.
b. How much did the soccer team spend?
Answer:
A) (15 x $3) + (10 x $2) + (12 x $1) = X
B) $77
Step-by-step explanation:
A) Each wrapping paper is 3 dollors, and they bought 15 (15 x 3)
Each greeting card is 2 dollors, and they bought 10 (10 x 2)
Each roll of ribbon is 1 dollors, and they bought 12 (12 x 1)
B) 15 times 3 is 45
10 times 2 is 20
12 x 1 is 12
45 + 20 + 12 = 77

A caterpillar moves across the grass at a rate of 4 feet every 7 minutes. How fast does the caterpillar move in feet per minute?
Answer:
0.57 feet per minute.
Step-by-step explanation:
If the caterpillar moves 4 feet every 7 minutes, it can be written as a ratio: 4/7. When you divide 4 by 7, you'll find the feet per minute rate.
The owner of a grocery store wants to mix two kinds of condy together to make 15lb that he can sell for $5.00 per lb. He wants to use chocolate candies that he sells for $7.00 per lb and sugar candies that he sells for $2.00 per lb. How many pounds of each should the owner use?
Answer: 6 pounds of sugar candy, and 9 pounds of chocolate candy.
Step-by-step explanation:
Let's define the variables:
C = pounds of chocolate candies used.
S = pounds of sugar candies used.
We know that he wants to make a total of 15lb, then:
C + S = 15
We also want that the price per pound to be equal to 5$.
This means that the price of the 15 pounds will be the same as the price of the un-mixed candies.
C*$7.00 + $2.00*S = $5.00*15
Then we have a system of equations:
C + S = 15
C*$7.00 + $2.00*S = $5.00*15
To solve this system, we need to start by isolating one of the variables, i will isolate C in the first equation:
C = 15 - S
now we can replace that in the other equation:
(15 - S)*$7.00 + $2.00*S = $5.00*15
Now we can solve this for S.
$105 - $5.00*S = $75
$105 - $75 = $5.00*S
$30 = $5.00*S
$30/$5 = S = 6
Then there are 6 pounds of sugar candy, and we can use the equation:
C + S = 15
C + 6 = 15
C = 15 - 6 = 9
There are 9 pounds of chocolate candy in the mix.
Answer:
9 pounds of chocolate candy
6 pounds of sugar candy
Step-by-step explanation:
x will represent pounds of chocolate candies used
y will represent pounds of sugar candies used
x + y = 15
x · $7.00 + $2.00 · y = $5.00 · 15
x = 15 - y
(15 - y) · $7.00 + $2.00 · y = $5.00 · 15
105 - $5.00 · y = 75
105 - 75 = $5.00 · y
$30 = $5.00 · y
$30 ÷ $5 = y
$30 ÷ $5 = 6
y = 6
x + y = 15
x + 6 = 15
x + 6 - 6 = 15 - 6
x = 9

Claire correctly solved the proportion StartFraction x over 4 EndFraction = StartFraction 36 over 16 EndFraction for x by using cross products to get the equation 16 x = 144 and then dividing both sides by 16 to get x = 9. She showed that she can use cross products to solve the proportion because she gets the same answer if the solves it as shown.
StartFraction x over 4 EndFraction = StartFraction 36 over 16 EndFraction. StartFraction x over 4 EndFraction times 4 = StartFraction 36 over 16 EndFraction times 4. x = StartFraction 144 over 16 EndFraction. X = 9.
What property allowed her to go from StartFraction x over 4 EndFraction = StartFraction 36 over 16 EndFraction to StartFraction x over 4 EndFraction times 4 = StartFraction 36 over 16 EndFraction times 4 ?
Answer:
The property used here is: Multiplication property of Equality
Step-by-step explanation:
Claire solved the expression [tex]\frac{x}{4}=\frac{36}{16}[/tex] by two ways
Way 1: Solving using proportion:
[tex]\frac{x}{4}=\frac{36}{16}[/tex]
By cross multiplying:
[tex]16x=144[/tex]
Divide both sides by 16
[tex]x=9[/tex]
Way 2:
She also solve the same expression [tex]\frac{x}{4}=\frac{36}{16}[/tex] by using following steps
Multiply both sides by 4
[tex]4\times( \frac{x}{4})=4\times(\frac{36}{16})\\x=\frac{144}{16}\\x=9[/tex]
We need to tell the name of property that allowed her to go from [tex]\frac{x}{4}=\frac{36}{16}[/tex] to [tex]4\times(\frac{x}{4})=4\times(\frac{36}{16})[/tex]
The property used here is: Multiplication property of Equality
The property states that if A , B and C are real numbers then
A = B and AC = BC are equivalent.
