Answer: x intercept is (-6,0) and y intercept is (0,-3)
Step-by-step explanation: the y intercept is when x=0. the x intercept is when y=0.
to solve this for the y intercept, we set x=0 in the equation y=-1/2x-3. so it would be y=-1/2(0)-3 therefore y= 0-3 and y=-3. the y intercept is (0,-3)
to solve for the x intercept, we set y=0. we plug it into the equation y=-1/2x-3 so 0=-1/2x - 3. this means we can change the sign of -1/2x from negative to positive and move it to the other side. so 1/2x=-3 to solve for x, we divide both sides by 1/2 so x=-6. so the x intercept is (-6,0)
The perimeters of two squares in the model are given. Find the perimeter of the third square. P=12 units p=16 units
Answer:
20 units
Step-by-step explanation:
1) find the side of the first square
side = P / 4 = 12:4 = 3 units
2) find the side of the second square
side = P / 4 = 16 : 4 = 4 units
3) use the Pythagorean theorem to find the hypotenuse of the right triangle
[tex]\sqrt{4^2 + 3^2} = \sqrt{16 + 9} = \sqrt{25} = 5[/tex] units
4) find the perimeter of the third square
P = side x 4 = 5 x 4 = 20 units
Answer:
20 units

the stove you have to bake in is an old one and only has the temperature in ° Fahrenheit. You are making rusks and have to dry them overnight at a temperature of 176°.Convert this temperature to ° Celsius
Answer:
[tex]80^{\circ} C[/tex]
Step-by-step explanation:
You are making rusks and have to dry them overnight at a temperature of 176° F.
The given temperature is in Fahrenheit. We need to convert it into °C.
The relation between Fahrenheit and °C is given by :
[tex]C=\dfrac{5}{9}(F-32)[/tex]
Put F = 176
So,
[tex]C=\dfrac{5}{9}(176-32)\\\\C=\dfrac{5}{9}\times 144\\\\C=80^{\circ} C[/tex]
So, the temperature is equal to [tex]80^{\circ} C[/tex].

which of the following lengths cannot be the lengths of a triangle? 4,6,9 a.) 3,4,2 b.) 2,2,3 c.) 1,1,2 d.)
Answer:
D. 1, 1, 2
Step-by-step explanation:
A triangles sides have to have the two smallest side's sum add up to be greater than the largest number. In D, 1+1 = 2, and 2 is the largest number, since 2 is not greater than 2, It cannot be a triangle.

I really need help on this question, because I forgot of how to find the angle of each variable.
Answer:
a = 38 degree
b = 54 degree
c = 54 degree
Step-by-step explanation:
a = 180 - 142 = 38 ( angle on a straight line is equal to 180)
To determine the value of b, we have to find the other missing angle in the triangle.
the value of the missing angle is 38
Alternate angles are equal. the missing angle is alternate to angle b which has a value of 38
b = 180 - (38 + 88) = 54
c = 54
What is the value of x in the equation −8 + x = −2?
Can the sides of a triangle have lengths of 3, 8, and 3
Explain??
Answer:
no
Step-by-step explanation:
the triangle rule is the sum of any two sides of a triangle MUST be larger than the third, in this case 3+8 > 3, but 3+3 < 8 so it cannot be a triangle
Answer:
An isosceles triangle has two side lengths that are the same and one side length that is different. Soo... basically to sum it up in a word, yep.

what is -2.3 -1.2
explain your answer
Answer:
-2.3 - 1.2 = -3.5
Step-by-step explanation:
when we’re doing negative adding means subtracting so what I idi was add 2.3 and 1.2 and I got 3.5 so I think what number is bigger it’s -2.3 so since it’s negtive I put a negative that’s how I got it
Will mark brainliest if done within 20 minutes of this being posted! NO LINKS NO FILES. Solve the radical equations and show your work, check your solutions too.
Step-by-step explanation:
5√x+3 = -20
÷5. : √x+3 = -4
square: x+3 = 16
-3: x = 13
√x+18 -2 = x -4
+2 : √x+18 = x -2
square: x+18 = x^2 - 4x +4
-18: x = x^2 -4x -14
-x : 0 = x^2 -5x - 14
foil: (x- 7) (x+2) = 0
x = 7, -2
Slope is written as a ratio of the vertical change (run) to the horizontal change (rise) between any two points on a line.
Answer:
Step-by-step explanation:
Yeah the equation is change in y over change in x; change in is represented with the delta sign, so y2-y1/x2-x1
