It’s c just to let you know I have done this before
To find the intersecting point, you have to put the two formulas equal to each other
First isolate the same variable, in this case y
So y=x-4
Now we can say
2x + 7 = x - 4
Now solve for x
X= 3
Now fill this in in either one of the formulas
Y= 2 (3) + 7
Y= 13
So they’ll intersect at (3,13)
Answer:
A. 99 cm^2
Step-by-step explanation:
The entire area including the non shaded part is equivalent to
15 x 9 cm
the entire area is 135 cm^2
The area of the square is equivalent to 6 x 6
the non shaded area is 36 cm^2
To find the shaded area you subtract the non shaded area from the shaded area
135-36
You are left with 99 cm^2 as the area of the shaded part of the figure.
Answer:
Step-by-step explanation:
Make an x and y table, and pick any values to plug in for x in the equation.
I will use the numbers from -2 to 2
Now plug in the values you picked for x into the equation to find its y-value
x = -2
y = 3x - 1 Plug in -2 for x
y = 3(-2) - 1
y = -6 - 1
y = -7
x = -1
y = 3x - 1
y = 3(-1) - 1
y = -3 - 1
y = -4
Do the same for the rest of the numbers, and graph each point and draw a line connecting them.
