Answer: The slope is 5/2.
Step-by-step explanation:
Convert the equation into slope intercept form, ( y=mx+b)
2y = 5x + 4 Divide each side by 2
y = 5/2x + 2 In this form the slope will be the coefficient of x variable.
The coefficient is the number that comes before x.
In this case, the slope is 5/2.
Which value is a solution of the equation 3 - 2x=-5?
02
04
0-2
01/5
Answer:
4
Step-by-step explanation:
answer is four don't worry it's correct
The value is a solution of the equation is x= 4.
The correct option is B.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have an Equation as 3- 2x = -5.
Now, solving the above equation for x
Subtract 3 from both side
3- 2x - 3 = -5 -3
-2x = -8
Now, divide both by (-2) we get
-2x/(-2) = -8/(-2)
x = 4
Thus, the value of x is 4.

Hayden likes building radio-control sailboats with his dad.One of the sails shaped like a triangle has side lengths measuring 6 inches 8 inches and 10 inches. To log her activity Hayden creates and collects drawings of all the boats she and her father built together. Using the scale factor of 1/4 creat a scale drawing of the sail.
Answer:
1.5 inches ; 2 inches ; 2.5 inches
Step-by-step explanation:
Given that the original measurement of the triangular sail is :
6 inches, 8 inches and 10 inches
Scale factor = 1/4
Hence, scaled diagram of the triangular sail :
1/4 * (6 inches, 8 inches, 10 inches)
1/4 * 6 = 1.5 inches
1/4 * 8 = 2 inches
1/4 * 10 = 2.5 inches

A truck can be rented from company A for $120 a day plus $0.50 per mile. Company b chargers $80 a day plus $0.70 per mile to rent the same truck. Part A write a equation. To find the number of miles in a day at which the rental costs for company A and company B are the same Part b solve the equation
Answer:
Part A: [tex].50x+120 = .70x+80[/tex]
Part B: [tex]200[/tex] miles
Step-by-step explanation:
So to start, we need to put this information into slope-intercept form. Slope intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] represents the slope of a line and [tex]b[/tex] represents the y-intercept. In this question [tex]y[/tex] represents the total cost of the rental, [tex]x[/tex] represents the number of miles driven, [tex]m[/tex] represents the price per mile, and [tex]b[/tex] represents the base price of the rental. Now that we know the variables, we need to plug in the information we have.
Since we know that company A charges $125 a day and $0.50 per mile we would have [tex]y=.50x+120[/tex]
Since we know that company B charges $80 a day and $0.70 per mile we would have [tex]y=.70x+80[/tex]
Now that we have two equations we can move onto the next step. We're looking to know the number of miles ([tex]x[/tex]) that would make the total cost ([tex]y[/tex]) equal. To do this we can make the equations equal each other since we know that [tex]y[/tex] will be the same.
Written out, the equation will look like this: [tex].50x+120 = .70x+80[/tex]
Now, we are trying to find [tex]x[/tex] so we need to isolate the variable.
To start we need to put [tex]x[/tex] on the same side so we'll subtract [tex].70x[/tex] from both sides to get [tex]-.20x+120=80[/tex]
Next, we'll subtract [tex]120[/tex] from both sides of the equation to get [tex]-.20x=-40[/tex]
Finally, we'll divide both sides by [tex]-.20[/tex] to get [tex]x=200[/tex]
This means that at [tex]200[/tex] miles, both companies will cost the same amount.

Use the figure to find the measures of the numbered angles.
Answer:
95 degrees is the measure of 3 just like the other angle because they equal each other the angle of 4 you would find out by subtracting 180-95=85. so the measure of 3 is 95 and the measure of 4 is 85
Souvenir hats, T-shirts, and jackets are sold at a rock concert. Three hats, two T-shirts, and one jacket cost $40. Two hats, two T-shirts, and two jackets cost $60. One hat and three T-shirts cost $10. Find the prices of the individual items. (you have to use substitution and/or elimination method, NO matrix or Graph.)
Answer:
j = 24
t = 2
h = 4
Step-by-step explanation:
Three hats, two T-shirts, and one jacket cost $40.
3h + 2t + j = 40
Two hats, two T-shirts, and two jackets cost $60.
2h + 2t + 2j = 60
One hat and three T-shirts cost $10.
h + 3t = 10
3h + 2t + j = 40 (1)
2h + 2t + 2j = 60 (2)
h + 3t = 10. (3)
From (3)
h = 10 - 3t
Substitute into (1) and (2)
3(10 - 3t) + 2t + j = 40 (1)
2(10 - 3t) + 2t + 2j = 60 (2)
30 - 9t + 2t + j = 40
20 - 6t + 2t + 2j = 60
- 7t + j = 40 - 30
-4t + 2j = 60 - 20
-7t + j = 10 (1a)
-4t + 2j = 40 (1b)
Multiply (1a) by 2
-14t + 2j = 20
-4t + 2j = 40
Subtract to eliminate j
-4t - (-14t) = 40 - 20
-4t + 14t = 20
10t = 20
t = 20/10
t = 2
Substitute t = 2 into
h = 10 - 3t
h = 10 - 3(2)
= 10 - 6
= 4
h = 4
Substitute t = 2 and h = 4 into
3h + 2t + j = 40
3(4) + 2(2) + j = 40
12 + 4 + j = 40
16 + j = 40
j = 40 - 16
= 24
j = 24

She hike 1.5 miles per hour.A common unit of measurement is the mile (mi).
How to fast she hike per hour?1.609344 kilometers are exactly one unit of length. mile, any of several different measures of distance, such as the statute mile, which has a length of 5,280 feet, is also equivalent to 1,760 yards (1.609 km). It derives from the mile passus, or "thousand paces," of the Romans, which was equivalent to 5,000 Roman feet.
A common unit of measurement is the mile (mi). It is typically used to express the distance between cities, the length of rivers, and the distance between roadways. The letter "mi" stands for the unit mile in writing. Therefore, a marathon race would be roughly 26.3 miles or 26.3 mi in length.
Given ,
1/4hrs=15mins
15mins=3/8miles
60mins=more

solve 2x-4y=10 and x+5y=40
Answer:
y = 1/2x + 2.5 and y = -1/5x + 8
Step-by-step explanation:
2x - 4y = 10 (subtract 2x on each side)
-4y = -2x + 10 ( divide by - 4 on both sides)
y = 1/2x + 2.5
x + 5y = 40 (subtract x on both sides)
5y = -x + 40 (divide by 5 on both sides)
y = -1/5x + 8

use the zero product property to find the solutions to the equation (x+2)(x+3)=12
Answer:
x=-6, x=1
Step-by-step explanation:
The zero product property
It states that if a.b=0, then it must be satisfied that a=0 or b=0. It's commonly used to solve equations where one of the sides is 0.
The given equation is:
(x+2)(x+3)=12
Since neither side is 0, we operate the expression:
x^2+3x+2x+6=12
Moving 12 to the left side and simplifying:
x^2+3x+2x+6-12=0
x^2+5x-6=0
Factoring:
(x+6)(x-1)=0
Now, since there is zero on the right side, we apply the property to solve:
x+6=0, or x-1=0
The two solutions come directly:
x=-6, x=1
6+4=210
9+2=711
8+5=313
3+2=15

has a length of 3.5 inches and width of 2.5 inches. If the scale of the
drawing is 1 inch = 5 feet, what is the actual perimeter of the fenced
area?
Answer: 73 feet
Step-by-step explanation:
1inch =5feet
L=3.5 inches W=2.5 inches
P= L1+L2+W1+W2
L=3.5(5) =17.5
W= 2.5(5) = 12.5

Two numbers that are the same distance from zero on a number line are called ___ numbers
Answer:
They are called opposites.
Step-by-step explanation:
"Zero is called the origin, and it's neither negative nor positive. For every positive integer, there's a negative integer an equal distance from the origin. Two integers that lie the same distance from the origin in opposite directions are called opposites. For example, negative 5 is the opposite of positive 5."
