Answer:
![y = {x}^{2} + 4](https://tex.z-dn.net/?f=y%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%204)
Step-by-step explanation:
First you can notice the y-intercept is 4. Then notice how the y value increases exponentially based on the x valie, making it non-linear, rather a porabla.
Answer:
personally none but it would be 35%-25%
(-5, 2) ⇒ x₁ = -5, y₁ = 2
(7, -1) ⇒ x₂ = 7, y₂ = -1
Slope:
![\bold{m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-1-2}{7+5}=\dfrac{-3}{12}=-\dfrac14}](https://tex.z-dn.net/?f=%5Cbold%7Bm%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cdfrac%7B-1-2%7D%7B7%2B5%7D%3D%5Cdfrac%7B-3%7D%7B12%7D%3D-%5Cdfrac14%7D)
Slope intercept form:
y = mx + b
Plug <em>m</em> and (7, -1) :
-1 = -¹/₄(7) + b
-1 + ⁷/₄ = b
<h3>b = ³/₄ ← y-intercept</h3>
Therefore slope intercept form of h(x):
<h3>h(x) = -¹/₄x + ³/₄</h3>
Answer:
8. 133°
9. 124°
Step-by-step explanation:
Because all triangles add up to 180°, the sum of all interior angle will add up to 180°.
8) 94 + 39 = 133
180 - 133 = 47
47° is the measure of the unknown interior angle, but we need the exterior and all straight lines are 180° angles, so we need to subtract.
180 - 47 = 133°
9)
81 + 43 = 124
180 - 124 = 56 (interior angle)
180 - 56 = 124° (exterior angle)
